PETITION FOR WRIT OF CERTIORARI TO THE
UNITED STATES COURT OF APPEALS FOR
THE NINTH CIRCUIT

Petitioners pray that a Writ of Certiorari issue to review
the Judgment of the United States Court of Appeals for
the Ninth Circuit entered on June 14, 1977, affirming the
Judgment of the United States District Court for the

onli

District of Oregon and the Order denying petitioners’
Petition for Rehearing entered August 4, 1977.

Opinions Below

The opinion of the District Court is reported unofficially
at 185 United States Patents Quarterly 807 and appears
at Appendix 1 herein. The opinion of the United States
Court of Appeals for the Ninth Circuit is reported
unofficially at 194 United States Patents Quarterly 415
and appears at Appendix 2 herein. The Order of the
Appeals Court denying petitioners’ Petition for Rehearing
appears at Appendix 3 herein.

Jurisdiction

The Judgment of the Court of Appeals was entered on
June 14, 1977, a timely decision for rehearing was denied
August 4, 1977, and this Petition for a Writ of Certiorari
was filed within 90 days of that date.

The jurisdiction of this court is invoked under 28 U.S.C.
§ 1254(1).

Questions Presented

1. Did the Court of Appeals deprive petitioners of their
property (the patent in suit) without due process of law in
violation of the Fifth Amendment by refusing to interpret
Section 103 of Title 35 of tae United States Code in
accordance with this Court’s direction set forth in Graham
v. Deere, Anderson’s-Black Rock v. Pavement Salvage Co.
and Sakraida v. Ag Pro.

_

2. Did the conduct of the Court of Appeals call for an
exercise of this court’s power of supervision to prevent a
grave miscarriage of justice, not only in this case but also in
future patent cases.

Constitutional and Statutory Provisions
and Rules Involved

This case involves the Due Process clause of the Fifth
Amendment of the Constitution of the United States and
Section 103 of Title 35 of the United States Code.

Statement of the Case

This is an action for infringement of Claim 5 of Dial
et al United States Letters Patent No. 3,313,433, filed
June 26, 1964, and issued April 15, 1967, for a “Floating
Cover For A Liquid Storage”’ (Appendix 6). The invention
was developed by plaintiff Globe Linings, Inc., a small
business located in Long Beach, California. The invention
consists of a floating cover for an open water reservoir to
prevent contamination of the stored water by deleterious
substances such as dirt, falling leaves, chemical sub-
stances in the air, bird and animal waste and refuse thrown
in by vandals. Although smaller water reservoirs can be
provided with fixed protective roofs, such a roof construc-
tion is too expensive for reservoirs of large surface area.
The patented invention solved the vexing problem of
removing rainwater from a flexible floating reservoir
cover.

This action arose when the defendant City of Corvallis,
Oregon, had an infringing cover constructed for its Baldy

—

Reservoir by defendant contractor S & T Construction
Co., Inc. The latter defendant utilized materials and

engineering provided by defendant Firestone Tire and
Rubber Co.

For the purpose of this Writ, it is important to note that
the invention of the patent in suit had no trouble meeting
the ‘“‘secondary considerations” referred to in this Court’s
direction in Graham v. John Deere Co., 383 U.S. 1, at 35-
36. Undoubtedly, the most striking evidence in this regard
was the failure of the U.S. Army and large manufacturers
(including the defendant Firestone herein) to solve the
problems inherent to a floating roof cover. Such failure
was well documented by a confidential Army Report which
detailed the unsuccessful attempts to solve such problems
from 1943 to the subsequent abandonment of the project
in approximately 1965. The Army Report summarized the
failure of the whole project as follows:

‘There does not appear to be a simple method of
handling water removal” (page 129); and “patterns
of rainwater accumulations on the surface of a
reservoir cannot be predicted or controlled with any
degree of certainty” (page 132). (Emphasis added)

Further evidence of nonobviousness was the skeptical
attitude those skilled in the reservoir art assumed towards
petitioners’ patented reservoir cover, the three-year
period required to develop such cover and the commercial
success achieved by the cover for the struggling plaintiff
Globe Linings, Inc. Yet another indication of nonob-
viousness was provided by the recognition by defendant

a

City of Corvallis that the patented cover of Globe Linings,
Inc. could solve the City’s contamination problems, such
recognition taking the form of an invitation to Globe
Linings to bid on the City’s reservoir cover. Unfortunately
for Globe Linings, defendants Firestone and S & T
Construction Company, Inc. made a lower bid. The lower
bid reflected the fact that neither of such defendants
needed to recoup the cost of developing and promoting the
infringing cover, but instead could merely copy plaintiffs’
patented cover.

There appears herebelow a copy of FIGS. 1 and 3 of the
patent in suit with the basic elements of Claim 5 at issue
thereof identified:

CONTINUOUS SHEET FIG.3
\ FLOAT MEANS .

RESERVOIR PERIPHERY

Such asic elements of Claim 5 at issue are:

(1) a continuous, flexible relatively thin sheet
which completely overlies the stored liquid - this
provides an inexpensive cover for large surface
areas and one which is conformable to the reservoir
configuration;

(2) the side of the sheet being larger than the
reservoir periphery - this provides excess material
capable of forming depending folds; and

(3) “float means”’ on the sheet and supporting
the sheet such that (or “whereby’’) the unsup-
ported sheet portion “forms a depending rainwater
collection sump” outwardly of the supported sheet
portion.

After the trial at Portland, Oregon, the trial court held
Claim 5 of the patent in suit invalid and unenforceable for
obviousness under 35 U.S.C. 103 based solely upon the
three references set forth herebelow. The court did not
rule on the issue of infringement:

— oa

1. ‘The U.S. Army Report describing the aban-
doned experiments referred to hereinabove, such
report being dated December, 1965.

2. Allen U.S. Patent No. 2,497,850, issued
February 21, 1950, Appendix 4 (cited during the
prosecution of the patent in suit).

3. Feild U.S. Patent No. 2,461,537, issued
February 15, 1949, Appendix 5 (not cited).

In finding obviousness, the trial court particularly relied
upon the Army Report, since such report was directed to
the rainwater collection problem, while Allen merely
discloses a rigid floating cover for a petroleum storage
tank, and Feild merely discloses a floating cover for a
closed tank. The trial court also ruled that applicants’
claimed combination of old elements failed to “produce an
unusual or surprising result”’.

On appeal, petitioners pointed out that since the patent
in suit was filed June 26, 1964, and the Army Report was
not published until December, 1965, such report could not
possibly constitute prior art, and accordingly that it was
error for the trial court to utilize the Army Report in
holding the patent claim invalid for obviousness and in
evaluating whether or not plaintiffs’ invention produced
unusual or surprising results over the prior art.

In its opinion (Appendix 2) the Court of Appeals agreed
with petitioners that the Army Report could not be
considered prior art. Rather than remand the case to the
trial court, the Court of Appeals then proceeded to hold

=

the patent in suit invalid for obviousness on the basis of
solely the Allen patent or the Feild patent! Specifically,
the Court of Appeals held that:

(1) since both Allen and Feild utilized covers
having a peripheral sump wherein liquid could
gather, the applicants’ use of such a sump was not
patentable “‘because a change in use is not a
patentable quality unless it is patented as a
process’”’;

(2) the use of the trough together with the inner
floats which automatically diverted rainwater from
the main body of the roof into the sump involved
insufficient ingenuity and was “no more than that
to be expected of a mechanic skilled in the art”
citing Cuno Engineering Corp. v. Automatic Devices
Corp., 314 U.S. 84; and

(3) the claimed invention consists only of a
combination of ideas which produces results that
would be “expected by one of ordinary skill in the
art and hence the patent claim did not exceed the
sum of its parts in “an unusual or surprising way”
so as to meet the “rather severe test’ for the
patentability of a combination patent required by
the Ninth Circuit Court of Appeals in Regimbal v.
Scymansky, 444 F.2d 333 (1971).

The invalidity ruling of the patent in suit by the Ninth
Circuit Appellate Court has destroyed a valuable property
right of plaintiffs. In particular, plaintiffs’ competitors can
now sell copies of plaintiffs’ floating roof cover at a lower

==

price than plaintiffs, since plaintiffs’ competitors need not
amortize the cost of developing and promoting their
covers. With respect to a large competitor, such as
defendant Firestone, plaintiffs do not have a country-wide
marketing organization. Accordingly, plaintiffs cannot
possibly meet Firestone’s competition now that plaintiffs
have been deprived of their legal monopoly afforded by
the patent in suit.

Reasons for Granting the Writ

A. Petitioners have been deprived of their property
right (the patent in suit) without due process of
law in violation of the Fifth Amendment by the
failure of the Ninth Circuit Court of Appeals to
interpret 35 U.S.C. 103 in accordance with the
directions set forth by this Court.

Patents have the attributes of personal property: 35
U.S.C. §261. The patent owner has a vested property
right that can be cancelled, revoked or amended only by
judicial proceedings that afford due process of law: Jowa
State University Research v. Sperry Rand Corp., (C.A. 4,
1971), 444 F.2d 406, 409.

The fundamental requisite of due process of law is the
opportunity to be heard: Grannis v. Ordean, (1914), 234
U.S. 385, 394. Petitioners submit that due process
requires not only that judicial proceedings be held, but
that they provide the patent owner with a “fair opportunity
procedurally, substantively and evidencially to pursue his
claim”: Blonder Tongue v. University Foundation, (1971),

=

402 U.S. 313. A holding of patent invalidity, in effect,
destroys a patent owner’s property. It amounts to a taking
of his property. If the holding of invalidity is based upon
substantive interpretations of the applicable patent
statutes which so far depart from the standards set by this
Court that they do not offer a patent owner such a “‘fair
opportunity”, petitioners submit that the property, the
patent, is taken without due process of law. In this case,
petitioners were deprived of a fair opportunity substan-
tively to pursue their claim. The Ninth Circuit Court of
Appeals, rather than interpreting 35 U.S.C. 103 in
accordance with the direction set forth by this Court in
Graham v. Deere, 383 U.S. 1; Anderson’s-Black Rock v.
Pavement Salvage Co., 396 U.S. 57, and Sakraida v. Ag
Pro, 425 U.S. 273, applied its own standards of ob-
viousness in holding the patent in suit invalid. Addi-
tionally, the Appellate Court went off on a legal frolic of its
own in holding the claimed combination invalid because
one of the claim elements had been used for a different
purpose in the prior art.

It is true that the Appellate Court, as usual, paid lip-
service to Graham v. Deere, stating that the well-known
mode of analysis set forth herebelow should be followed:

“While the ultimate question of patent validity is
one of law . . . the §103 condition . . . lends
itself to several basic factual inquiries. Under
§ 103, the scope and content of the prior art are to
be determined; differences between the prior art
and the claims at issue are to be ascertained; and
the level of ordinary skill in the pertinent art

oe, ene ne

a a re et oe

—\

resolved. Against this background, the obvious-
ness or non-obviousness of the subject matter is
determined.”

After approving the above language, the Appellate
Court then ignored one of the most critical directions
thereof, i.e., a determination of “‘the level of ordinary skill
in the pertinent art”. A review of the Court’s opinion
(Appendix 2) reveals that the Court did not make any
attempt to evaluate the level of ordinary skill in the
reservoir art.

The failure of the Appellate Court to determine the level
of skill in the reservoir cover art made it quite impossible
for the Appellate Court to intelligently apply the re-
maining factual criteria of Graham v. Deere. This is true
since what may not have been obvious to one having a
lower than ordinary level of skill might be obvious to one
having a higher than ordinary level of skill.

In this case, it is clear that the Appellate Court did not
bother to determine the level of skill in the art for the
simple reason that such Court had no intention of applying
the statutory test for patentability set forth in 35 U.S.C.
103. Instead, the Court applied a hindsight test based
upon the Court’s “‘gut’’ reaction that the cover con-
struction of the patent in suit was so simple as to not be
entitled to the legal monopoly promised by Article 1,
Section 8, Clause 8 of the Constitution. Such hindsight
approach was demonstrated by the Appellate Court’s
dissection of the Feild and Allen patents and rearranging
the elements thereof to synthesize Claim 5 at issue.

=27(1)
Change in use is not patentable
quality unless patented as a _ process.

10. Patents
has already been put to use, albeit in a
different manner, is invalid; in order
to be valid over the prior art, it must
claim not novel use, but novel concep-
tion.

{10} Both the Feild and Allen patents
include a float means arranged with a
flexible material to form a_ trough
around the edge and the Feild patent
uses floats near the periphery in a way
very similar to that described in the Dial
patent. The major elements of claim 5
of the Dial patent were (1) the continu-
ous sheet of material extending beyond
the area of stored liquid, (2) the use of a
float means to support the cover and
form a fold outwardly from the float
means, and (3) the use of a perimeter
sump to collect and remove rainwater.
The collection of rainwater in the periph-
eral sump was accomplished by the rais-
ing of the inner floats, thus causing the
rainwater to flow downward to the deep
peripheral fold or trough.

Because the main significant elements
of the Dial patent claim 5 were already
found in the prior art, the final inquiry
is whether the raising of the height of
the inside floats and the use of a pump
to drain the water from the trough were
obvious. We conclude that they were.

There was testimony by appellant's ex-
pert ® that the Allen patent arrangement
would collect rainwater, whether or not
that was its stated purpose. The use of
the trough to collect water was therefore
a change in use, not structure. The rais-
ing of the inner floats to create a run-
off was arguably a change in structure,
but the ingenuity required to effect the
adaptation was “no more than that to be
expected of a mechanic skilled in the
art.” Cuno Engineering Corp. v. Auto-
matic Devices Corp., 314 U.S. 84, 92, 62
S.Ct. 37, 41, 86 L.Ed. 58 (1941).

[11] Because a patentable invention
is lacking, secondary considerations such
as “commercial success” and “long-felt
but unfulfilled needs” cannot fill the
gap. Graham v. John Deere Co., 383
U.S. 1, 35-36, 86 S.Ct. 684, 15 L.Ed.2d
545 (1966); Great Atlantic & Pacific Tea
Co. v. Supermarket Equipment Corp.,
340 U.S. 147, 153, 71 S.Ct. 127, 95 L.Ed.
162 (1950).

III.

COMBINATION PATENT

Appellant suggests that the float ar-
rangement of the Dial patent to locate
the excess material at the periphery of
the reservoir was an unusual or surpris-
ing result not found in the prior art. It
also makes reference to the ability of the
float means to keep the cover from sink-
ing if punctured, and to the raising of
the inner floats. In so doing, appellant
attempts to persuade this court that its
invention satisfies the “rather severe
test” for patentability of a combination
patent. See Regimbal v. Scymansky, 444
F.2d 333, 338-39 (9th Cir. 1971). We
must therefore decide whether the
“whole” of this patent claim exceeds the
sum of its parts in an unusual or surpris-
ing way.

We hold that it does not, but rather
consists only of a combination of ideas
which produces results that would be
“expected by one of ordinary skill in the
art.” Hewlett-Packard Co. v. Tel-De-
sign, Inc., 460 F.2d at 629-30.

The judgment of the district court is
affirmed.

The present invention relates to a floating cover for a
liquid storage reservoir, and more particularly to a float-

ing cover adapted to rise and fall with the level of the
stored liquid, according to the consumption and replen-
ishment thereof

It is an object of the present invention to provide a
floating cover which will protect the liquid in a storage
reservoir from small animals and birds and from dele-
terious substances such as dirt, radioactive fallout, and
the like, and which is strong enough and sufficiently well
supported by flotation means to support relatively heavy
loads, such as the weight of snow. The invention is par-
ticularly adapted for use in conjunction with conven-
tional water reservoirs characterized by sloping side walls,
although it can also be used in conjunction with reservoirs
and tanks having vertical walls. Such water reservoirs
usually contain large volumes of water and it is impor-
tant that the cover utilized to protect the water be rela-
tively inexpensive and yet be capable of accommodation
to the varying water areas as the water level rises and
falls in the slope-sided reservoir.

Another object of the invention is to provide such a
floating cover which is adapted to define a drainage and
expansion section or sump for concentrating rain water
so that it may be periodically removed, as by pumping
or the like.

Yet another object of the invention is to provide a
floating cover for a water reservoir which is supported
upon the surface of the water by a plurality of sets of
flotation units, and wherein each sect of flotation units
defines an unsupported area therebetween which tends to
collect rain water. A system of drainage pipes or lines
is provided with inlet openings in communication with
each of these unsupported areas for removing the col-
lected rain water.

It is also an object of the invention to provide a means
for anchoring the floating cover relative to the bottom
of the reservoir to constrain the cover against lateral
movement, which might occur by virtue of strong winds
sweeping laterally across the surface of the reservoir.

Another object of the invention is to provide a floating
cover which can be installed in a water reservoir for pro-
tection of the stored water without the necessity of re-
moving any of the water therefrom, and which includes
a fap or flaps which can be opened to afford access to
the umlerside of the cover and to the interior of the
resei voir for maumenance purposes and the like.

A further object of the invention is to provide a float-
ing cover which can be installed in a water reservoir for
protection of the stored water without the necessity of
removing any of the water therefrom, and which is adapt-
ed for support by a plurality of cables or the like dis-
posed therebeneath during emptying of the reservoir for
maintenance or repair of the reservoir.

Other objects and features of the invention will become
apparent from consideration of the following description
taken in connection with the accompanying drawings, in

Referring now to the drawings, the floating cover of
the present invention is designated generally by the
numeral 10 and is illustrated in association with an
earthen reservoir 12 which in the present instance is
rectangular in shape. The particular reservoir 12 is char-
acterized by downwardly and inwardly slanting or slop-
ing side walls 14, as best viewed in FIGS. 2 and 3, which
are usually formed by a compacted subgrade 13 of earth
covered with a relatively thin layer 18 of asphalt of
cement treated material.

By virtue of the fact that the reservoir 12 has sloping
side walls, the area at the upper extremity or periphery
of the reservoir is greater than the corresponding area
at the base or bottom of the reservoir and the cover 10
must be adapted to accommodate itself to the difference
in area as the level of the water rises and falls accord-
ing to the Consumption and replenishment thereof.

The cover 10 is continuous sheet of material, such as
flexible, relatively thin butyl rubber shecting or vinyl,
polyethylene or like film impervious to and adapied tw
completely overlie the water in the reservoir 12 in co-
extensive relationship to the reservoir periphery. The
sheeting or film is preferably fabtic reinforced for im-
proved tear strength. The size or area selected for the
cover 10 is such that it is appreciably greater than the
arca of the reservoir periphery, that is the periphery of
the reservoir at its upper extremity. With this arrange-
ment, wrinkles or folds 16 are formed in the cover 10,
and tend to develop adjacent the periphery of the reser-
voir 12 for reasons which will become apparent herein-
after.

The peripheral or free edges of the cover i@ are
anchored in position in substantially air and fluid-tight
relationship by a peripherally continuous sheet anchor 18
adjacent the uppermost extremity of the reservoir. Any
suitable shect anchor 18 for maintaining the cover 10
in position in substantially fluid-tight relationship is satis-
factory. One exemplary form of sheet anchor 18 is illus-
trated in FIGS. 1, 3, and 4. In this cunstruction, the
anchor 18 comprises a fixed puriion 22 which extends
about the periphery of the reservoir 12 and is convenient-
ly made of concrete firmly embedded in the subgrade 13.
Facing elements 26 are arranged coextensive with the
fixed portion 22, and are constituted of elongated lengths
of timber arranged in abutting relation at their ends.
Each anchor 18 also includes a plurality of movable por-
tions which each comprise an elongated concrete block
3 and a coexiensive facing element 32 made of a wooden
timber or the like. The plurality of blocks 3@ and
associated elements 32 are arranged in confronting rela-
tionship to the facing elements 26 and the fixed portion
22 of the sheet anchor so that the wooden facing ele-

a

3,313,:4%

ments 26 and 32 define jaws initially spaced apart to re-
ceive the outer margin of the cover 10. The movable
and fixed portions of the shect anchor are then moved
together to clamp the edge of the cover 10 therebetucen
by operating a plurality of nut and bolt asseniblies, one
of which is illustrated at 34 in FIG. 4. With the pro-
vision of the continuous shect anchor 18, ut will be ap
parent that the cover 10 may be quickly installed with-
out having to remove any of the water from the reservour
and without having to make any special anchorages of
provisions for anchorages in the botiom of sides of the
reservoir. In addition, a fluid-tight relationship is pro-
vided between the cover 1@ and the periphery of the
reservoir.

In order to obtain access to the underside of the cover
10 and the interior of the reservou, four flaps are
provided at the four corners of the cover 10, each flap
36 being defined by a right angular cut in the cover 10,
suitably strengthened by reinforcing strips and secured in
closed pusition by lacing 38 or the dike.

The cover 1® is floated or buoyed upon the surface
of the stored water by a plurality of float units 40 so
that in the event that the cover 10 1s accwentally torn,
it is prevented from sinking to the bottom of the reservoir
and thereby complicating repair of the cover. The cover
10 could also be floated by employing the float arrange-
ment of FIGS. 9-12, as will subsequently be described,
or the cover 10 could itself be made floatable by making
it of a material such as fcamed plastic having positive
buoyancy and characterized by marginal flexible portions
of the neutral or negative buoyancy. However, utiliza-
tion of the float units 4@ is preferable where it is desired
to drain water from the cover 10 from a number of
different points over the surface thereof

Each float unit 40 is made of buty! rubber and is
provided with ag inflation valve 43 extending above the
surface of the cover 10. That is, each float unit is affixed
to the underside of the cover by three straps 42 secured
to the underside ot the cover by a plurality of suitable
fasteners 44, the inflation valve 43 for cach float unit ex-
tending upwardly through a suitable opening in the cover
so that the unit may be easily inflated or deflated.

The float units 40 are preferably arranged in sub-
stantially uniformly distributed sets of four, the four units
of each set being oriented to define a rectangular bay
41 or unsupported area therebetween. With this arrange-
ment, rain water tends to collect in the unsupported areas
defined by the sets of float units, making it possible to
pump or otherwise drain this water off the surface of
the cover by pumping from each bay 41, as will be seen.

In addition, it is particularly noted that the float units
4@ are spaced away from the outer periphery of the
cover 1@ to define an unsupported peripheral area con-
stituting an expansion and drainage section or sump, which
is designated in FIG. 1 by dash-dot lines extending about
the periphery of the cover 1@ and identified by the numeral
46.

The area of the sump 46 is completely unsupported by
float units so that the excess material in the cover tends
to develop the folds 16. Then, as rain water collects
upon the surface of the cover, the rain water tends to
flow to the lower, unsupported arcas of the cover, com-
prising both the bays 41 and the sump 46. The water in
the sump 46 forces the folds 16 more deeply into the
stored water as the volume of rain water increases. Drain-
age of the rain water to the sump 46 may be increased
by selectively inflating the float units 4@ so that the more
interiorly disposed float units ride higher on the reservoir
water cause the rain water to flow exteriorly or oulward-
ly into the sump 46.

In certain applications water collection in the area of
the sump 46 is sufficient without resorting to the inflatable
float units 4@, and in these instances an arrangement like
that illustrated in FIGS. 9-12 can be used. as will be
more particularly described hereinafier.

A plurality of flexible drain lines 48 are arranged to
extend across the cover 1@ as best illustrated in FIG. 1,
and afe each provided with inlet openings $@ in com-
munication with the unsupported bays 41 defined by
each set of the float units 40. One extremity of each of
the drain lines 48 is capped or closed, as at 49, and the
opposite extremities of the lines are connectej to a mani-
fold drain line $2 extending transversely of the lines 48
at one end of the reservoir. In addition, a continuous
sump drain line $4, normally located at a level below
that of the line $2, extends about the periphery of the
cover and is provided along its length with openings (not
shown) in communication with the sump 46.

The manifold line $2, as best illustrated in FIG. 2,
is connected by a flexible drain line $6 to a drain conduit
$8 secured by a bracket $9 to the facing element 32 in
the berm 2@ of the reservoir. The drain conduit $8 is
made of a length sufficient that it will reach the manifold
line $2 at the lowest level to which the water in the res-
ervoir falls. The drain conduit 58 is connected to any
suitable pump or drainage means (not shown) whereby
the rain water collected in the bays 41 can easily be re-
moved.

The sump drain line 54 is connected by a flexible drain
line 6@ to a drain conduit 61 which is located alongside
the drain line $6 and is connected to the facing element
32 by the same bracket $9 which secures the drain con-
duit 58. Like the flexible line $6, the line 6@ is made of
a length sufficient that it will reach the sump line $4 at
its lowest leve! within the fold 16 defining the sump 46.
The drain conduit 61 is connected to the same pump or
drainage means (not shown) to which the drain conduit
58 is connected so that the pump can take a suction on
either or both of the conduits, as will be apparent to
those skilled in the art.

The cover 1@ is constrained against lateral movement,
as might occur by virtue of a wind sweeping across the
surface of the reservoir, by a plurality of anchors 62 rest-
ing upon the bottom of the reservoir. Each anchor 62
is connected to the cover by a flexible line 64 made of a
length sufficient to accommodate the rise and fall of the
cover 10 during use of the reservoir, the upper end of
cach line 64 being secured to a fitting 66 which is adhered
or otherwise secured to a reinforced section 68 of the
cover 10.

Referring now to FIGS. 9 through 12, there is illus-
trated another cover in accordance with the present inven-
tion, designated generally by the numeral 70. The cover

in °
The size of the cover 7@ is greater than the area of
\he reservoir at its upper periphery so the
are formed at the outer margin of the cover 70, as was
the case with the cover 10. The cover 7@ is fabricated by
securing to:ether a plurality of elongated strips of the
cover material, the seams between such strips being best
illustrated in FIG. 11. The adjacent margins of the
cover strips are arranged to form a lap join any
able adhesive 72 is interposed between the lap portions
of the strips to secure them together.

A plurality of elongated floats 74 and 75 are secured
to the underside of the cover 70, as best illustrated in
FIGS. 9 and 10, by a suitable adhesive 76. The floats
74 extend perimetrically along the sides and ends of the
cover 7@ in a rectangular configuration and, in one em-
bodiment, are approximately 12 inches wide. Each float
74 is elongated and abuts the adjacent floats at its ends.
Each float 74 and 75 includes a central portion 78 made
of buoyant material such as one of the well known pias-

=

$3,313,443

tic or rubber foam materials, and also includes an outer
casing 80 made of butyl rubber and completely envelop-
ing the portion 78.

The peripheral band of floats 74 are spaced from the
edge margin of the cover 70 and define the unsupported
sump portion 46 between the marginal floats and the edge
of the cover 70. In addition, the plurality of floats 75,
preferably of lesser width than the marginal floats 74,
extend across the cover beneath each of the seams be-
tween the cover strips. Thus, the pattern of floats 74 is
a rectangular perimeter of floats, the floats 75 constitute
a plurality of strings of floats across the cover in parallel,
spaced relationship to one another.

Rain water collects in the sump 46, as previously de-
scribed in connection with the first embodiment, by forc-
ing the folds 16 deeper into the water stored in the
reservorr.

Referring now to FIG. 12, the edge margins of the
cover 70 are secured in position adjacent the berm cf

the reservoir in substantially fluid-tight relationship by a :

peripherally continuous concrete footing 82 firmly em-
bedded in the subgrade 13. The footing 82 includes a
plurality of equally spaced siuds 84 embedded therein, and
a plurality of elongated anchor elements 86 are arranged
in end-abutting relationship along the length of the foot-
ing 82 and are each provided with suitable openings for
receiving the uprer ends of the studs 80. The margin
of the cover 7@ is also provided with similar openings
for the studs 80 so that the cover may he secured in po-
sition by first disposing the margin thercof in position
upon the studs 80 and thereafter placing the anchor
clements 86 in position so that the cover 70 i, sandwiched
between jams constituted by the elements 86 and the
upper surface of the footing 82. A plurality of nuts 88
are then threaded upon the plurality of studs 8@ to
firmly secure the cover 7@ in position.

With the arrangement just described, no provision aeed
be made for pumping rain water from the central por-
tions of the cover. Rather, the arrangement of floats
74 has been found to float the cover high enough in the
reservoir water that rain water can drain into the sump
46 for removal by any suitable pump (not shown).
Thus, the sump 46 can be drained merely by disposing a
flexible drain line in any portion of the sump and taking
a suction until the collected water is removed, as will be
apparent.

The footing 82 also includes a plurality of peripherally
spaced and embedded |-bolts 98, each I-bolt on one side
of the reservoir having its counterpart located in the con-
fronting footing 82 on the opposite side of the reservoir.
With this arrangement supporting cables 92, indicated in
dash-dot outline in FIGS. 10 and 11 can be disposed be-
neath the cover 70 and connected at their opposite ex-
tremities of the I-bolts 90. The cables 92 thus extend
bencath the cover in parallel relationship, as indicated
by the paralici dush-dot lines 94 in FIG. 9, so that when
it is desired to repuir the bottom or side walls of the reser-
voir, the stored water can be emptied and the cover 70
supported or suspended above the reservoir floor. The
cables 92 may be installed beneath the cover and attached
to the I-bolts 90 when the cover is first installed, if suffi-
cient slack is provided in the cables to permit the cover
to rise and fall with the change in level of the stored
water, or the cables may be installed only when it is
desired to empty the reservoir. In this case, skin divers
can easily install the cables in their proper positions.
Although not shown, the underside of the cover 70 in
the area of the cubles ix preferably suitably reinforced
by adhesively securing an eatra thickness of buty! sheet-
ing, thereby reducing possible abrading of the underside
of the cover by the cables 92.

From the foregoing it will be apparent that a floating
cover has been provided which is adapted to not only ac-
commodate itself to the rise and fall of the water level
in a reservoir, but which is also adapted to define a sump

area adjacent the periphery of the reservoir for the col-
lection of rain water whereby the rain water may be
easily pumped away or otherwise removed. In addition,
the cover completely overlies the water in the reservoir
and prevents contamination of the water by deleterious
substances or by small animals and birds.
