The claim of letters patent No. 187,100, granted to John Clark,
February 6th, 1817, for an "improvement in cheese formers for cider
presses," namely, "The guide frame D, in combination with an
extended pomace rack, and a cloth to enclose a layer of pomace
therein, substantially as described," is invalid because it did not
require invention to use the described guide frame in connection
with the racks and the cloths.
The racks and the cloths had been before used in connection, and
an enclosure was used with them, which enabled the operator to make
the pomace of uniform depth on each rack, and prevented the lateral
spreading of the pomace, and it required only ordinary mechanical
skill and judgment to make cider the guide frame or the rack of the
desired size.
This was a bill in equity to restrain the infringement of
letters patent. Answer denying the validity of the patent. Decree
below for respondent from which complainant appealed. The case is
stated in the opinion of the Court.
MR. JUSTICE BLATCHFORD delivered the opinion of the Court.
This is a suit in equity brought in the Circuit Court of the
United States for the Northern District of New York for the
infringement of letters patent No. 187,100, granted to John Clark,
February 6, 1877, for an "improvement in cheese formers for cider
presses," on an application filed September 11, 1876. The
specification and drawings of the patent are as follows:
"The object I have in view is in laying up a 'cheese' for the
cider press, where each layer is folded up in a cloth, to
Page 119 U. S. 336
secure uniformity of thickness of all the layers in the mass or
cheese, and thus secure uniform pressure on its entire area, and to
avoid all tendency to break the pomace frames or rack."

To this end, it consists in the employment of a guide frame in
combination with extended pomace racks, as more fully hereinafter
set forth. Figure 1 is a perspective view, showing the manner of
laying up a cheese in press. Figure 2 is a cross-section

xx. In the drawing, A represents the lower framework
of a cider press, on which is laid a bed, B. C is a pomace rack,
which may be rigid, as shown, or flexible, as described in letters
patent No. 148,034, issued to me March 3, 1874. On this rack is
laid a guide frame D whose bottom girts are not spaced far enough
apart to extend the full length of the rack on which they rest. A
cloth E, large enough to envelop the layer, is then laid on the
rack inside the frame and opened out to receive the pomace, which
is "struck" level with the girts of the frame, after which the
cloth is folded over the leveled pomace and the frame is lifted
off. The next and succeeding racks are in like manner laid on the
first and filled up, and a follower is placed on the upper one,
when the cheese is ready to press. Laid up in this way, the several
layers are uniform in thickness, and the cheese, in mass, is level
on top and offers a uniform resistance to the pressure over its
entire area, thus assuring the expression of all the juice and
precluding all danger of breaking the pomace racks. If the bed B be
extended, a cheese may be built upon a board while one is being
pressed, and then be slid under the follower when the first one is
removed.
The claim is in these words: "The guide frame D in combination
with an extended pomace rack and a cloth to enclose a layer of
pomace therein, substantially as described."
The answer sets up as defenses want of novelty, want of
patentability, and public use for more than two years before the
application for the patent. After a hearing on proofs, a decree was
made adjudging the patent to be invalid and dismissing the bill.
The plaintiff has appealed.
The decision of the circuit court, 17 F. 79, proceeded on these
grounds: (1) cloths and also racks and also guide frames having
each been used before, the aggregation of them, as described in the
patent, was not a valid combination; (2) the use of the described
guide frame in connection with the racks and cloths did not involve
intention; (3) the precise combination described in the patent was
in public use more than two years before the patent was applied
for.

Without examining any other question raised in the case, we are
of opinion that the patent must be held void on the second ground
above mentioned. A rack on which to place the pomace was old, and a
cloth to cover the pomace lying on the rack was old, the two being
used in connection, and an enclosure was used with them, which
enabled the operator to make the pomace of uniform depth on each
rack and prevented the lateral spreading of the pomace. The only
point of the invention would seem to be the use of a guide frame
smaller than the rack, or in other words the use of a rack larger
than the guide frame. There was no invention in making the guide
frame or the rack of the desired size. It required only ordinary
mechanical skill and judgment. Within the recent cases in this
Court on the subject, the patent must be held void.
