The first claim in reissued letters patent No. 5294, granted
February 25, 1573, to the Collins Company, as assignee of Lucius
Jordan and Leander E. Smith, for an improvement in wrenches was
only the application to the bar of the Coes wrench (which was an
existing patented invention
Page 130 U. S. 57
at the date of the alleged invention of Jordan and Smith) for
the purpose of securing and supporting the step, and resisting the
strain of a nut already in use on the Hewitt or Dixie wrench, and
as such it lacks the novelty of invention requisite to support a
patent within the recent decisions of this Court, and this
conclusion is not affected by the fact that in complainant's
wrench, the screw-rod of the Coes wrench is availed of instead of
the screw-sleeve of the Dixie wrench.
The second claim in said reissue is for "the nut F, combined
with the wrench-bar, and interiorly recessed at
d, for the
purpose set forth." Some years later, the patentee filed in the
Patent Office a disclaimer thereto
"except when said recessed nut and wrench-bar are in combination
with the handle G, the step or step-plate E, the screw-rod C, and
the movable jaw B of the wrench, substantially as is shown and
described in said last mentioned reissued letters patent,"
being the reissue in question.
Held that whether this
qualified disclaimer was or was not effectual, it was, in view of
the fact that the screw-rod and movable jaw of the patent had no
different effect from the screw-sleeve and movable jaw of the prior
Dixie wrench upon the other parts of the combination, an admission
that the second claim of the patent is void for want of
novelty.
The third claim of the patent is also void for want of
novelty.
In equity. The Court in its opinion stated the case as
follows:
The Collins Company of Connecticut, a corporation located at
Collinsville, in the County of Hartford and State of Connecticut,
brought this suit in equity in the Circuit Court of the United
States for the District of Massachusetts, against Loring Coes and
Melvin O. Whittier, partners in business at Worcester, in Worcester
county, Massachusetts, in the name and style of Loring Coes &
Co., for the alleged infringement of reissued letters patent No.
5,294, dated February 25, 1873, for an improvement in wrenches,
issued to the Collins Company as assignee of Lucius Jordan and
Leander E. Smith, said reissued letters patent being based upon
original letters patent dated October 10, 1865, No. 50,364. There
had also been a reissue February 22, 1870.
The specification and accompanying drawings of the reissue No.
5,294 are as follows:
"The object of this invention is the prevention of end thrust or
back pressure on the wooden handles of wrenches, which has
heretofore availed to quickly destroy such wooden handles,
Page 130 U. S. 58
and, in destroying the handles, has left the working parts of
the wrench which depended upon the handles for support without such
support, so as to injure and effectually impair their working
qualities and efficiency, and is accomplished by so connecting the
step which forms a bearing for the lower end of the screw-rod with
the bar which forms the main part of the wrench that the back
pressure upon the step by the screw-rod will be directly
transmitted to the wrench-bar at the place of connection therewith,
and will not be transmitted to and mainly put upon the wooden
handle."
"Fig. 1 is a side view of the whole wrench, the part below the
dotted line,
xx, being in section. Fig. 2 is a top or plan
view of the step, which forms a bearing for the lower end of the
screw-rod. "
image:a
"The letter A indicates the wrench-bar, flat sided down to the
under side of the step, E, and from thence downward cylindrical, or
of other convenient shape, so as to take upon it the wooden handle,
G. B is the movable jaw. The letter C indicates the screw-rod, and
D the rosette by which it is turned. The letter E indicates the
step, in which is the bearing,
s, for the lower end of the
screw-rod, and also the hole,
a, to admit the bar, A, and
fitting up against the shoulder,
b. On the bar, A, just
below the step, E, is cut the screw-thread,
i, on which
screws the nut, F, forming a projection from the wrench-bar, on
which rests the step, E, and thus transmits the back pressure put
upon the step directly to the wrench-bar at the place
Page 130 U. S. 59
of connection therewith, and thus relieves the wooden handle
therefrom, the connection of the step with the bar being made in
such manner that the step may be removed or taken off the bar
without any cutting or abrasion of parts."
"The nut not only supports the step, but can be made to rigidly
fasten the step to the bar by screwing it firmly up against the
step, so as to gripe it between itself and the shoulder,
b, thus giving the nut, so to speak, a double office,
viz., that of supporting the step and also, that of
fastening it rigidly to the bar. The nut is interiorly recessed at
d for the purpose of forming a ferrule for the top of the
wooden handle."
"Heretofore the part designed to perform the office of the step,
E, has rested directly on the wooden handle, which was secured upon
the bar by a light nut,
o, at the lower extremity of the
bar, which is the present method of fastening on the handle."
"It is known that previous to this invention, steps have been
forged or otherwise produced solid with the bar, and this became as
much a part of it as the solid head at extremity of bar, and also
by riveting to reach similar result, but such method, by making a
permanent fastening, renders it impossible, or a work of great
difficulty, to displace the step in order to remove the sliding jaw
for repairs. It will be observed that while Jordan and Smith's
method of fastening is as firm as the permanent fastenings last
above referred to, their step can readily be removed and again put
in place at pleasure."
"It is believed that Smith and Jordan were the first to secure
easy divisibility of step and bar, together with a fixed or
stationary step when in position, and at the same time supporting
the step when in position immediately by the bar, and not
immediately through the handle, as the manner had been."
"As a matter of definition, the Jordan and Smith method of
fastening and supporting the step when in position is denominated
'removable' hereinafter in contradistinction from a connection and
support made by forging or otherwise producing the step in one
solid piece with the bar, and therefore a part of it, or by
riveting it thereto, or the like. "
Page 130 U. S. 60
"
Claims"
"1. The step, combined with the wrench-bar, and supported by the
nut, F, or its equivalent at the place where the step is connected
with the bar, in such manner that the step can be removed from the
bar without cutting or abrasion of parts."
"2. The nut, F, combined with the wrench-bar, and interiorly
recessed at
d, for the purpose set forth."
"3. The nut, F, combined with the threaded bar, and performing
the office of supporting the step, and also of rigidly fastening it
to the bar, for the purpose set forth."
April 16, 1841, a patent issued to Loring Coes for what has
since always been known as the "Coes Wrench," and this was reissued
June 26, 1849. The specification and drawings of the reissue are as
follows:
"Figure 1 is an elevation of my improved wrench, and figure 2 an
elevation of a wrench previously known, but not of my invention. In
my improved wrench, the inner jaw slides on the bar of the
permanent jaw and handle, and is moved by a screw at the side of
the bar, operated by a head or rosette, which always remains in the
same position relatively to the handle, whereby the moveable jaw
can be adjusted with the thumb of the hand, which grasps and holds
the handle. The principle or character of my invention, and that
which distinguishes it from all other things before known, consists
in moving the adjustable jaw by means of a screw placed at the side
of and parallel with the bar of the permanent jaw and handle, when
the required rotation for sliding the jaw is given by a rosette or
head, or the equivalent thereof, which retains the same position
relatively to the handle, and my invention also consists in
retaining the required position of the rosette, or its equivalent,
by which the required motion is given to the sliding jaw, by having
its periphery to work in a notch or recess in the bar of the
permanent jaw and handle, or
vice versa. In the
accompanying drawings, A represents a quadrangular bar of metal
with a permanent or hammer jaw, C at one end, the other end being
reduced in size to pass through a handle,
Page 130 U. S. 61
L, secured to it by a nut, M. Between the ferrule of the handle
and the shoulder of the bar an iron plate, I, is griped by the
securing of the handle onto the bar, and this plate extends out
sufficiently beyond the bar to receive the journal, K (see dotted
lines) of a screw, F, which is placed parallel "
image:b
"with, and by the side of, the bar. The screw is tapped into a
tubular piece, D, that projects from the back face of the
adjustable jaw, B, which is fitted to slide on the bar from or
toward the permanent jaw, C, the rear end of the tubular
projection, D, being provided with, and sustained by, a bridle, E,
which embraces and slides on the bar. At the rear end, the screw is
provided with a head or rosette, G, the periphery of which turns in
a notch or recess, H, made in the edge of the bar, as shown by
dotted lines, by which the position of the said rosette is retained
relatively to the handle. The hand, represented by dotted lines,
indicates the manner in which my improved wrench is operated. The
handle is grasped by the fingers, and the rosette is operated by
the thumb of the same hand, so that, without any change in the
position of the hand, the movable jaw can be moved toward or from
the permanent jaw, to set the wrench to any size required, with one
hand."
"By means of my improvement, the bar can be made of any desired
form best adapted to the sliding jaw and to strength.
Page 130 U. S. 62
The rosette, or its equivalent, employed for operating the jaw
is always retained in the same position relatively to the hand that
gripes the handle. At the same time, the use of two bearings for
the screw is avoided."
"The advantages of my improved wrench over other methods of
construction will be seen by comparison with the wrench represented
by figure 2 of the accompanying drawings."
"What I claim as my invention and desire to secure by letters
patent is moving the sliding jaw by a screw, combined with and
placed by the side of and parallel with the bar of the permanent
jaw and handle, substantially as described, when the required
rotation for sliding the jaw is given by the head or rosette (or
its equivalent), which retains the same position relatively to the
handle during the operation, substantially as described. And I also
claim moving the sliding jaw by a screw, combined with and placed
by the side of, and parallel with, the bar of the permanent jaw and
handle, substantially as described, in combination with the
rosette, or its equivalent, retained in its position relatively to
the hand in the manner described."
It appears from the evidence that during the years 1851 to 1854,
E. F. Dixie was manufacturing, to the extent of from 200 to 400
wrenches per week of various sizes, a wrench known as the "Hewitt
Wrench," which wrench contained a recessed nut screwed upon the
wrench-bar just above the wooden handle, for the purpose of
relieving the handle from back pressure put upon the step, and of
serving as a ferrule for the upper end of the wooden handle. It had
an adjusting screw-sleeve, instead of the adjusting screw-rod of
the Coes wrench, but was otherwise substantially the same. The
following diagrams give the various wrenches referred to on the
argument:
Page 130 U. S. 63
image:c
Page 130 U. S. 64
On the 9th of August, 1880, the Collins Company filed a
disclaimer in the Patent Office, stating:
"Further, that said the Collins Company has reason to believe
that, through inadvertence and mistake, the second clause of claim
made in said last-mentioned reissued letters patent, in the
following words, to-wit: '2. The nut, F, combined with the
wrench-bar, and interiorly recessed at
d, for the purpose
set forth' is too broad, including that of which said Jordan and
Smith were not the first inventors. Said the Collins Company
therefore hereby enters its disclaimer to 'the nut, F, combined
with the wrench-bar, and interiorly recessed at
d, for the
purpose set forth,' except when said recessed nut and wrench-bar
are in combination with the handle, G, the step or step-plate, E,
the screw-rod, C, and the movable jaw, B, of the wrench,
substantially as is shown and described in said last-mentioned
reissued letters patent,"
being the reissue in question.
The defendants contend that the patent in suit did not disclose
a patentable invention in view of the prior state of the art; that
the reissue described and claimed a different invention from that
for which the original patent was granted; that the reissue was
taken too long after the date of the original patent to be
permitted upon equitable grounds, and that there was no
infringement.
The circuit court originally granted an interlocutory decree in
favor of the plaintiff, in accordance with the opinion of Judge
Lowell, reported in 5 Bann. & Ard.Pat.Cas. 548 and 3 F. 225.
But a rehearing was afterwards moved for and granted, the
interlocutory decree vacated, and the bill dismissed for the
reasons stated in the opinion of MR. JUSTICE GRAY, presiding in the
circuit, in a similar suit by the plaintiff against other
defendants, which opinion was as follows:
"This is a bill in equity for the infringement of the first
claim in the specification of the second reissue to the
complainant, dated February 25, 1873, of letters patent originally
issued to Lucius Jordan and Leander E. Smith, on October 10, 1865,
for an improvement in wrenches. The wrench, as described, both in
the original patent and in the reissue, has the following parts:
the wrench-bar, A,
Page 130 U. S. 65
the upper part of which is of the usual shape and has attached
to it the movable jaw, B, and the lower part of which is of
convenient form to receive upon it the wooden handle; a screw-rod,
C, parallel to the main bar; a rosette, D at the lower end of the
screw-rod, by means of which the movable jaw is worked; a ferrule,
or step, E, having a hole through it for the admission of the bar,
and a recess in its upper face as a bearing for the lower end of
the screw-rod; a nut, F, screwed on a thread in the bar, under the
step, and having a recess in its under face to receive the top of
the wooden handle, G, and the wooden handle secured at its lower
end to the main bar by a nut in the usual way."
"Both the original patent and the reissue state that the object
of the invention is to make the strain come upon the nut, F,
instead of coming upon the wooden handle. The original patent
states that the nut, F, is, and the reissue states that it may be,
screwed up firmly against the step, E. The reissue affirms and
repeats that the distinguishing characteristic of the invention is
that the step can be readily removed and replaced at pleasure.
There is no hint of such a distinction in the original patent."
"The first claim of the original patent is for 'the step, E,
made substantially as described, and for the purpose set forth.'
The corresponding claim in the reissue is for"
"the step, combined with the wrench-bar, and supported by the
nut, F, or its equivalent at the place where the step is connected
with the bar, in such manner that the step can be removed from the
bar without cutting or abrasion of parts."
"The parallel screw-rod, with a rosette thereon to work the
movable jaw, and resting upon a ferrule or step, had been
introduced in the original Coes wrench, patented in 1841, and, long
before the issue of the patent to Jordan and Smith in 1865, large
numbers of the Hewitt or Dixie wrench had been made and sold in
which there was no separate screw-rod, and the screw that worked
the movable jaw revolved on the main bar, but that screw rested on
a ferrule or step, which was secured sometimes by driving it on
under heavy pressure, and sometimes by a nut screwed under it on
the bar. "
Page 130 U. S. 66
"The application to the bar of the Coes wrench, for the purpose
of securing and supporting the step, and resisting the strain, of a
nut already in use for the same purpose on the Hewitt or Dixie
wrench lacks the novelty of invention requisite to support a
patent, within the decisions of the supreme court at the last term,
which have in effect overruled the earlier decision of this court
in the suit of this complainant against Loring Coes and others,
reported in 5 Bann. & Ard.Pat.Cas. 548;
Pennsylvania
Railroad v. Locomotive Engine Safety Truck Co., 110 U. S.
490;
Bussey v. Excelsior Mfg. Co., 110 U. S.
131;
Double-Pointed Tack Co. v. Two Rivers Mfg.
Co., 109 U. S. 117;
Phillips v.
Detroit, 111 U. S. 604."
"The complainant's patent being void for want of novelty, it
becomes unnecessary to consider the other defenses."
"Bill dismissed, with costs."
MR. CHIEF JUSTICE FULLER, after stating the facts as above,
delivered the opinion of the court.
We concur with the circuit court in its disposition of this case
and the grounds upon which it rested its decision. The wrench-bar,
the fixed jaw upon its upper end, the movable jaw sliding upon the
wrench-bar, the screw-rod parallel with the wrench-bar, the rosette
upon the lower end of the screw-rod, the step-plate surrounding the
wrench-bar, the wooden handle secured by the nut at its extreme
lower end, are all described in the patent to Coes, and the nut
screwed upon the wrench-bar just below the step-plate, and provided
with a recess for the purpose of forming a ferrule for the top of
the wooden handle, which is not in the Coes patent, but is in
complainant's reissue, had already been in use in the Hewitt or
Dixie wrench for the same purpose. The disclaimer conceded that
"the nut, F, combined with the wrench-bar, and
Page 130 U. S. 67
interiorly recessed at
d, for the purpose set forth,"
was an old device, but it is claimed that the device is new when
the recessed nut and wrench-bar are in combination with the handle,
the step, the screw-rod, and the movable jaw. The handle, the step,
the screw-rod, and the jaw are all to be found in the Coes and
Dixie wrenches, and the recessed nut of the Dixie wrench
constituted, by the shoulder which it made at its upper end, a step
upon which the screw rested, and served every purpose designated in
the reissued patent in suit as intended to be secured by such
recessed nut. This in itself justified the finding that
"the application to the bar of the Coes wrench, for the purpose
of securing and supporting the step and resisting the strain, of a
nut already in use, for the same purpose, on the Hewitt or Dixie
wrench, lacks the novelty of invention requisite to support a
patent."
This conclusion is not affected by the fact that in
complainant's wrench the screw-rod of the Coes wrench is availed of
instead of the screw-sleeve of the Dixie wrench.
Complainant's first claim is as follows:
"1. The step, combined with the wrench-bar, and supported by the
nut, F, or its equivalent at the place where the step is connected
with the bar, in such manner that the step can be removed from the
bar without cutting or abrasion of parts."
The specification says:
"On the bar, A, just below the step, E, is cut the screw-thread,
i, on which screws the nut, F, forming a projection from
the wrench-bar, on which rests the step, E, and thus transmits the
back pressure put upon the step directly to the wrench-bar at the
place of connection therewith, and thus relieves the wooden handle
therefrom, the connection of the step with the bar being made in
such manner that the step may be removed or taken off the bar
without any cutting or abrasion of parts."
The elements of this combination are the support of the step by
the nut, F, the transmission of back pressure directly to the
wrench-bar through that nut, and the removability of the step
without cutting or abrasion of parts. Now the Dixie wrench
contained the nut, F, screwed on the wrench-bar, and transmitting
the back pressure directly to it, and removable without cutting or
abrasion, by being simply unscrewed.
Page 130 U. S. 68
The second claim is: "The nut, F, combined with the wrench-bar,
and interiorly recessed at
d, for the purpose set forth."
This, as so stated, was disclaimed, except when said recessed nut
and wrench-bar are in combination with the handle, the step, the
screw-rod, and the movable jaw.
It was said in
Hailes v. Albany Stove Company,
123 U. S. 582,
123 U. S. 587,
the Court speaking through MR. JUSTICE BRADLEY:
"A disclaimer is usually and properly employed for the surrender
of a separate claim in a patent, or some other distinct and
separable matter, which can be exscinded without mutilating or
changing what is left standing. Perhaps it may be used to limit a
claim to a particular class of objects, or even to change the form
of a claim which is too broad in its terms; but certainly it cannot
be used to change the character of the invention. And if it
requires an amended specification or supplemental description to
make an altered claim intelligible or relevant, while it may
possibly present a case for a surrender and reissue, it is clearly
not adapted to a disclaimer."
The complainant's qualified disclaimer is an admission that the
second claim of the patent is void for want of novelty, which is
true even if the qualification were effectual, since, as we have
seen, the screw-rod and movable jaw of the patent have no different
effect from the screw-sleeve and movable jaw of the prior Dixie
wrench upon the other parts of the combination.
The other claim is:
"3. The nut, F, combined with the threaded bar, and performing
the office of supporting the step, and also of rigidly fastening it
to the bar, for the purpose set forth."
The specification says:
"The nut not only supports the step, but can be made to rigidly
fasten the step to the bar by screwing it firmly up against the
step, so as to gripe it between itself and the shoulder,
b, thus giving the nut, so to speak, a double office,
viz., that of supporting the step, and also that of
fastening it rigidly to the bar. The nut is interiorly recessed at
d, for the purpose of forming a ferrule for the top of the
wooden handle."
The purpose of supporting the step by the nut, F, and fastening
the step rigidly to the wrench-bar by means of that nut, is the
relief of the wooden
Page 130 U. S. 69
handle from the strain of back pressure. In the Dixie wrench,
the step and nut were made of one and the same piece of metal,
thereby fully attaining the object of holding the step-plate
rigidly fastened in position. In the Coes wrench, the step was
rigidly fastened to the bar by being griped between a shoulder
above it and upon the bar and the handle below it, which was backed
up by the nut screwed upon the lower extremity of the bar.
Dispensing with a washer between a nut and that upon which it acts
makes no change in the office of the nut. The action of the nut, M,
of the Coes wrench in griping the step-plate is the same as that of
the nut, F, of the patent. This third claim is also void for want
of novelty.
The decree of the circuit court is affirmed.
