The fifth claim in letters patent No. 220,889, issued to Edmund
B. Taylor, October 21, 1879, for improvements in machines for
pouncing hats,
viz.:
"5. The combination of the support for the hat and the
self-feeding pouncing cylinder, whereby the hat is drawn over the
support B in the direction of the motion of the pouncing
cylinder,"
was anticipated by the second claim in letters patent No.
97,178, issued November 23, 1869, to Rudolph Eickemeyer.
This was a bill in equity to recover damages for the
infringement of two letters patent for improvements in machines for
pouncing hats,
viz.: patent No. 97, 178, issued November
23, 1869, to Rudolph Eickemeyer, and patent No. 220,889, issued
October 21, 1879, to Edmund B. Taylor.
In his specification Taylor states:
"The object of my invention is to dispense with feed rolls and
hat blocks in machines for pouncing hats, to make the cutting or
pouncing cylinder self-feeding, to enable the operator to control
the speed and direction in which the hats to be pounced pass over
the cutting or pouncing surface by the hand with the assistance of
a guard and presser pin, and to cause the material to be pounced to
move in the same direction as the surface of the self-feeding
cutter in contact with it, thereby avoiding the injurious strain to
which it is subjected in ordinary hatpouncing machines with feed
rolls or their equivalents."
"With my machine, not only can hats be pounced without any
stretching or straining of the material to be pounced, but hats of
different styles can be pounced, or different parts of the same
hats can be pounced more or less, as may be desired, without any
change in the adjustment of the machine. . . . "
Page 148 U. S. 483
"My machine consists of a table or supporting frame, X, which
carries the bearings, F, for the shaft, upon which is fixed the
driving pulley, E, and the self-feeding pouncing cylinder, A, which
can be revolved at any desirable speed. This self-feeding cylinder
is covered with the pouncing or cutting material."
"A block, B, supports the hat or material to be pounced, and
presses it against the self-feeding pouncing cylinder, A. This
block is adjustable upon its middle point by means of a bolt tapped
into it, which passes through the bracket, D, and is fastened by a
nut, M. It is supported by the bracket, D, which turns on a pivot,
and is operated by a treadle and lever, P, and connecting rod, O. .
. ."
"A guard, C, is placed directly over the supporting block to
protect the hands of the operator from contact with the
self-feeding pouncing cylinder, and is adjustable upon the bracket,
D, by the means of the nut, R, which works in a stirrup in the
guard. . . ."
"The mode of operating my machine is as follows: the hat to be
pounced is placed over the supporting block and pressed against the
self-feeding pouncing cylinder by means of the treadle operating
the swinging bracket. The self-feeding pouncing cylinder, revolving
at great speed, draws the hat through the space between the
supporting block and the self-feeding pouncing cylinder. The hand
of the operator, assisted when necessary by the presser pin, L,
retards the hat in its passage, and controls its direction, by
which means the pouncing surface can be caused to move over the
material to be pounced at any rate of speed or in any direction
that may be desired."
The only claim alleged to be infringed was the fifth, which
reads as follows:
"5 The combination of the support for the hat and the
self-feeding pouncing cylinder, whereby the hat is drawn over the
support, B, in the direction of the motion of the pouncing
cylinder."

Upon a hearing upon pleadings and proofs in the circuit court,
the court found in favor of the plaintiff upon the second claim of
the Eickemeyer patent, but also found the fifth claim of the Taylor
patent to be invalid for want of novelty, and dismissed the bill as
to this patent. 36 F. 317. Defendants did not appeal from the
decree against them as to the Eickemeyer patent, but plaintiff
appealed from so much of the decree as related to the patent to
Taylor.

MR. JUSTICE BROWN, after stating the facts in the foregoing
language, delivered the opinion of the Court.
The fifth claim of the Taylor patent was held to be invalid by
the court below upon the ground that it was anticipated by the
second claim of the Eickemeyer patent.
The operation of cutting or grinding off the rough surface of
the wool or fur of which the hat is made by the use of pumice is
termed "pouncing." This was formerly done by pumice or sandpaper
held in the hand, and applied to the frame of the hat, laid upon a
flat surface, and to the crown, fitted over a hat block of
corresponding shape. In time, mechanical devices began to be
employed for the same purpose. Originally this mechanism consisted
simply of a block over which the hat body was stretched, and to
which a rotary motion was imparted, while the pouncing material was
held in the hand, and applied to the surface of the hat. The patent
to Wheeler & Manley of August 14, 1866, contained an
improvement upon this, and consisted in pouncing the hat body by
means of an emery cylinder or other pouncing surface moving at a
high speed in contact with or against a hat body revolving at a
comparatively low speed. This machine, however, consisted of two
separate devices, one for pouncing the crown of the hat, and the
other for pouncing the brim. The patent to Nougaret of September
18, 1866, also provided for two separate devices, one to pounce the
crown and the other the brim. Like the Wheeler and Manley crown
machine, the Nougaret device for pouncing the crown contained a
revolving hat block for carrying the hat, but the subordinate
devices for bringing the different parts of the hat block in
contact with the pouncing roller differed somewhat in the two
machines. The patent to Labiaux of March 26, 1867, was simply for
an improvement in the crown machine of Nougaret, and consisted in
the manner of hanging and operating the shafts upon which the
pouncing roller and block were secured, and in the manner of
securing and holding the sandpaper to the pouncing roller, and in
some other minor particulars.
The patent to Eickemeyer of November 23, 1869, was a decided
advance upon previous devices in the fact that the
Page 148 U. S. 486
crown of the hat was so supported that both the crown and the
brim were presented by the same instrument to the pouncing
cylinder. 25 F. 496. In his specification, he stated his method of
accomplishing this as follows:
"My invention further consists in an arrangement of the pouncing
cylinder, and a rest or supporting horn for the hat body, which can
be introduced within the crown to support it against the cutting
action of the pouncing cylinder during the operation of pouncing,
the arrangement being such as to dispense with the use of a hat
block in pouncing the tips and side crowns of the hats."
The second and third claims of this patent -- the only ones
material to be considered -- read as follows:
"2. The arrangement and combination of a rotating pouncing
cylinder with a vertical supporting horn, substantially as
described, whereby the supporting horn may be used to support the
tip, side crown, or brim during the operation of pouncing the
hat."
"3. In combination with a rotating pouncing cylinder and a rest
or supporting horn, a swiveling feeding mechanism, substantially as
described, whereby the hat may be drawn between the pouncing
cylinder in different curves, or directly forward, as
required."
The Taylor patent was applied for May 21, 1879. The fifth claim
of the specification, as originally drawn, read as follows:
"5. The combination of the pouncing cylinder and the support for
the hat, whereby the hat is drawn over the moving pouncing cylinder
in the direction of the motion of the cylinder, substantially as
described."
As thus drawn, this claim was rejected by the examiner upon
reference to the Eickemeyer patent of March, 1874, which does not
appear in the record, but which, it may be presumed, was
substantially the same as the patent of 1869 in this particular.
The specification was thereupon amended by inserting before the
words "pouncing cylinder," wherever they occurred, the word
"self-feeding," and the fifth claim was amended to read as
follows:
"5. The combination of the support for the hat and the
self-feeding pouncing cylinder whereby the hat is drawn
Page 148 U. S. 487
over the moving pouncing cylinder in the direction of the motion
of the cylinder, substantially as described."
In his communication to the Patent Office, the patentee
suggested in support of this amended claim that it differed from
the claim of the Eickemeyer patent of 1874 in the fact that the
cylinder was a self-feeding one, and its operation was to cause the
material to be pounced to move in the same direction as the
pouncing material. In reply, the examiner expressed a doubt as to
what was meant by the clause in the fifth claim, "whereby the hat
is drawn over the moving pouncing cylinder in the direction of the
motion of the cylinder," and suggested that it should read,
"whereby the hat is drawn over the support, B, in the direction of
the motion of the pouncing cylinder." In reply, the fifth claim was
withdrawn, and two other claims proposed, as follows:
"5. The combination of the support for the hat and the
self-feeding pouncing cylinder, substantially as described."
"6. The self-feeding pouncing cylinder, which feeds the material
to be pounced to the moving pouncing surface in the direction of
its own motion."
Attention was also called to the fact that this was the only
machine that was self-feeding. "It does not," said the
patentee,
"depend upon feed rolls for pouncing the hat, but the pouncing
cylinder is the only force that moves or presents the hat to the
pouncing surface. The claim is for the combination of the
self-feeding pouncing cylinder with the support for the hat, as
described, in which the only motive power is the rapidly revolving
pouncing cylinder. This is believed to differ from all previous
machines which contain a feeding apparatus which controls the hat
as it is applied to the pouncing cylinder. As can be seen, in
Taylor's patent, but one cylinder or roll is used, and this solely
for the purpose of pouncing the hats, and not in any way for
feeding the hat, except by its direct motion."
These claims were rejected upon the ground
"that the pouncing roller of all hat-pouncing machines has a
tendency to move the material acted upon in the direction of its
motion, but feed rolls have been added to facilitate the feeding of
the article to be operated upon to the
Page 148 U. S. 488
pouncing cylinder, and it is not deemed invention or improvement
in the art to omit the feed rollers."
The claim was again amended and allowed in the following
form:
"5. The combination of the support for the hat and the
self-feeding pouncing cylinder, whereby the hat is drawn over the
support, B, in the direction of the motion of the pouncing
cylinder."
It does not clearly appear why the claim was allowed in this
form, since it seems to be open to the same objections that had
been previously made to it, when presented in slightly different
language.
These proceedings in the Patent Office are set forth in detail
for the purpose of showing the exact particulars which were then,
and are now, claimed to distinguish the Taylor patent from the
Eickemeyer patent of 1869. These are: 1. the omission of the feed
roll of the Eickemeyer patent; 2. the self-feeding characteristic
of the pouncing cylinder. An examination of the two devices shows
that they are practically the same, except that in the Taylor
patent the feeding roll of the Eickemeyer machine is omitted, and a
guard and presser pin substituted. The fifth claim of the
Eickemeyer patent of 1869, and the second claim of the Taylor
patent, are also for the same elements, namely a pouncing cylinder,
called "rotating" by Eickemeyer and "self-feeding" by Taylor, and a
support for the hat block, termed a "vertical supporting horn" by
Eickemeyer, though the operation of these elements is differently
described in the two claims. In the Eickemeyer claim, it is said
that "the supporting horn may be used to support the tip, side
crown, or brim during the operation of pouncing the hat," and in
the Taylor claim that "the hat is drawn over the support, B, in the
direction of the motion of the pouncing cylinder." It is insisted,
however, that the feed roll, though omitted in the second claim of
the Eickemeyer patent, is contained in the third, and, being an
essential element of his device, should be read into the second
claim as if it had been actually incorporated in it. If it were
true that the feed roll were necessary to the operation of the
combination of the second claim, this result would undoubtedly
Page 148 U. S. 489
follow; in other words, if a person has invented a combination
of three elements, all of which are necessary to the operation of
his device, he cannot, by making a claim for two of them, forestall
another, who has so combined these two elements that they perform
the same function that the three elements of the former patent
performed.
On examination of Eickemeyer's device, however, it is difficult
to see wherein the feed roll is so far essential to the operation
of the machine that it would not perform practically the same
function as the Taylor patent if the feed roll were omitted. There
would still be left a support for the hat by and upon which it
could be held up to the pouncing cylinder. The feeding of the hat,
instead of being accomplished or assisted by the feed roll, would
be done entirely by hand, as contemplated in the Taylor patent.
Indeed, all the significance of the word "self-feeding" in this
connection appears to be that when the hat is pressed against the
pouncing cylinder, it has a tendency to feed in the direction in
which the cylinder revolves, and it is difficult to see why in
either machine the hat may not be fed in the opposite
direction.
In the Eickemeyer machine, it was fed in the opposite direction
by the aid of the feeding roll, and the same thing, it would seem,
may be done, by the application of a little more force, in the
Taylor patent.
The case then really resolves itself into the question whether
the omission of the feed roll involves invention, and, in view of
the fact that the hat support and pouncing cylinder of the
Eickemeyer patent will accomplish practically the same functions as
the Taylor device, though not so perfectly, we hold it does not --
in other words, it required no invention to omit the feed roll of
the Eickemeyer patent and to make the subsidiary changes necessary
to produce a working device.
The truth is, the essence of the Taylor invention was the guard,
C, and the presser pin, L, and any argument which tends to prove
that the feed roll was an essential part of the Eickemeyer device
is equally cogent to show that the guard and presser pin are
essential to the Taylor patent, since they were designed to take
the place of the feed roll and assist the
Page 148 U. S. 490
operator in bringing every part of the hat in contact with the
pouncing cylinder. He himself speaks of the presser pin as
"a peculiar and novel feature' of his machine, its operation
being as follows: 'The hat to be pounced can be caused to be
revolved about it as a center by means of the pressure exerted upon
it, so that every part of the hat, except that immediately under
the presser pin, would, in its rotation, come in contact with the
pouncing cylinder, and by lessening the pressure, the hat would be
drawn under the presser pin in any desired direction, and that part
of it which had formed the center of rotation would then be
pounced."
As either, the guard or presser pin or both are made an element
in all the claims of his patent but the fifth, it is quite evident
that this was his real invention, and that his fifth and last claim
was suggested by a desire to make his patent as sweeping as
possible.
It is true that the Taylor machine seems to be capable of doing
more work, and at less expense for labor and pouncing material,
than the prior devices, which it appears to have largely
supplanted; but this consideration, while persuasive, is by no
means decisive, and is only available to turn the scale in cases of
grave doubt respecting the validity of the invention.
The decree of the court below, holding the fifth claim of this
patent to have been anticipated by the second claim of the
Eickemeyer patent, is therefore
Affirmed.
