Pope Manufacturing Company v. Gormully, ante,
144 U. S. 224,
applied to this case so far as the claim for recovery based upon
contract is concerned.
Claims 2 and 3 in letters patent No. 249,278, issued November 8,
1881, to Albert E. Wallace for an axle bearing for vehicle wheels
are void for want of novelty.
Claims 2 and 3 in letters patent No. 280,421, issued July 3,
1883, to Albert E. Wallace for an improvement upon the device
covered by his patent of November 8, 1881, are also void for want
of novelty.
This was a bill in equity for the infringement of letters patent
No. 249,278, issued November 8, 1881, to Albert E. Wallace, for an
axle bearing for vehicle wheels, and patent No. 280,421, issued
July 3, 1883, to the same person, and for a similar device. In
addition to the usual allegations of the bill for an infringement,
it was alleged that the defendants were bound by certain covenants
in the contract of December 1, 1884, entered into with the
plaintiff, in which they acknowledged the validity of these patents
and agreed not to manufacture ball bearings such as described and
shown, and made the subject matter of its claim, and that they are
therefore estopped to deny the validity of such patents, and that
it was also stipulated in said agreement that the devices such as
were being made by the defendants were contained in said
Page 144 U. S. 255
patents, and covered by the claims thereof, whereby the
defendants were estopped to deny infringement.
The court below held that the defendants were not estopped by
this contract, that the patents were invalid, and that if valid
they were not infringed, and dismissed the bill, from which decree
the plaintiff appealed to this court. 34 F. 896.
MR. JUSTICE BROWN, after stating the facts in the foregoing
language, delivered the opinion of the Court.
As we have already held in the case between the plaintiff and
defendant Gormully, No. 204, that the contract of December 1, 1884,
did not operate to estop the defendants from contesting the
validity of these patents, it is not necessary to consider this
case any further so far as the claim for recovery based upon this
contract is concerned. The case must be tried as an ordinary suit
in equity for the infringement of a patent.
(1) Patent No. 249,278, to Albert E. Wallace, is for an
improvement in axle bearings for vehicle wheels. The object of the
invention seems to have been the construction of a ball bearing in
two parts in such manner as to admit of the wear of the balls being
taken up gradually, as the wear progresses, in order to keep the
bearings tight. In reference to this, he says in his
specification:
"Heretofore many anti-friction bearings have been made and
described including various forms of ball bearings, and the latter
class have been constructed so as to be adjustable for wear by
having the bearing-box made in two or more parts, and so that they
may be made to approach each other to tighten the bearings. In
respect to bearings for light wheels, particularly for bicycles, it
is desirable to make the
Page 144 U. S. 256
parts as light and snug and of as little material as possible
consistently with strength. To make them true -- that is, so that
the balls shall be perfect spheres and of even diameter, and that
the bearing surfaces in which they revolve shall be of even
distance apart and of even curvature and shape and shall be kept
so, and that in putting together and adjusting the bearing parts
shall be made to approach each other with perfect evenness. It is
also desirable to make the parts and their joints as few as
possible, so that the structure composed of them, when put together
and in operation, shall not be liable to displacement, breakage, or
accident. It is the object of my improvement to secure these
desirable qualities in an adjustable anti-friction ball bearing and
to obviate the difficulties and imperfections existing in previous
attempts in this direction."
The second and third claims only are alleged to have been
infringed. They are as follows:
"2. The described anti-friction bearing for a wheel and axle,
consisting of a one-part bearing-box and a two-part sleeve, having
a circular row of balls within said box and between bearing
surfaces in the box and on either part of the sleeve, and adapted
for adjustment for wear and securement in position on an axle by a
screw thread at the outer end of one part of the sleeve, operating
to draw it to wards and from the other part, substantially as set
forth."
"3. The described anti-friction bearing for a wheel and axle,
consisting of a two-part collar or sleeve adapted to enclose the
axle, a one-part bearing-box enclosing said sleeve and containing a
recess with bearing surfaces between which and a bearing surface on
either part the said sleeve is held, a circular row of balls
combined and constructed essentially as shown and described, for
securement in position and adjustment for wear by the pressure of
one part of the sleeve against the hub of the wheel, and by an
external thread on the other part of the sleeve operating in an
internal thread in a boss secured to the axle on the opposite side,
substantially as set forth."
In reference to the adjustability of his device, he says
that
"it is obvious that this bearing will be readily adjustable
to
Page 144 U. S. 257
compensate for any wear of the bearing parts by simply loosening
the set screw, and turning the collar, S1, so that the thread shall
force it further into the bearing-box, the impinging of the
surface,
p1, upon the balls tending to send them to and a
properly close bearing upon the surfaces,
qq and
pp1, as in putting the parts together."
The essence of this patent, as we gather from the drawings and
the application, consists of two sleeves sliding upon the axle from
opposite directions, the inner ends of which are each beveled, so
that when the ends are brought together, or nearly so, they will
form a V-shaped groove upon the axle, the inner one of these
sleeves resting upon the hub of the axle and the outer one
connected with the crank both the crank and the sleeve being
threaded with a screw. Upon the axle is fitted a solid bearing-box
with a similar V-shaped groove containing metallic balls, and
adapted to be partly retained in the groove upon the axle formed by
the two beveled sleeves, one of which is made adjustable, so as to
approach very near to or in contact with the other sleeve, and thus
take up the wear of the balls by narrowing the V-shaped groove in
which they are contained.
The use of ball bearings for bicycle and other wheels was so
common at the date of this patent that it is needless even to
allude to the large number of prior patents upon this subject.
Bearing in mind that the peculiarity of this patent consists in
a sleeve of two parts adapted for adjustment for wear and
securement in position by a screw thread at the outer end of one
part of the sleeve, operating to draw it towards and from the other
part, we find practically the same device in the English patent to
James Bate, for improvements in velocipedes, dated November 14,
1878. Figure 20 of this patent indicates in section a method of
affixing and adjusting the cones of a velocipede front or back axle
bearing. A fixed cone corresponding to the plaintiff's sleeve, S,
is screwed onto a spindle, and has a sleeve formed solid therewith,
and screwed inside and out. Another adjustable cone, corresponding
to plaintiff's sleeve, S, is screwed upon the sleeve, and is locked
by a nut or collar, also screwed upon the sleeve. The groove
corresponding
Page 144 U. S. 258
to the V-shaped groove of the plaintiff's patent is formed by
the contact of these two cones, precisely as in the Wallace patent,
and the feature of adjustability is attained by screwing the
adjustable cone upon the sleeve as far as necessary to tighten the
bearings, and even up to actual contact with the fixed cone. So far
as the object to be accomplished is concerned, it makes no
difference which one of these cones is adjustable, so long as it
affords opportunity for a gradual tightening of the bearing. If
there be any difference between this and the Wallace patent, it is
not such a difference as affects the essential feature of both --
namely that of adjustability or such as to involve any patentable
novelty.
The English patents to Lewis, of 1879, and to Bown and Hughes,
of March, 1880, also exhibit a somewhat similar device of a loose,
adjustable cone, but the resemblance to the Wallace patent is not
so obvious as in case of the Bate patent.
As the Bate patent anticipates every valuable feature of the
second and third claims of the Wallace patent, it is unnecessary to
consider the question of infringement.
2. Patent number 280,421, granted July 3, 1883, to the same
party, is for an improvement upon the device covered by the prior
patent, and consists in providing the inner sleeve of that patent,
which surrounds the axle and rests against the hub of the wheel,
with a flange annulus, and attaching to the hub and wheel a locking
button which engages with notches or teeth on the edge of the
annulus and locks it to the hub so that the sleeve will always turn
with the axle or hub. This construction also provided for an
adjustment of the inner sleeve on the axle as well as the outer
sleeve.
Another modification of this patent, not contained in the first,
consists in the construction of the bearing-box. In the first
patent, the bearing-box was attached directly to the frame of the
machine, while in the second it is placed within a shell, which in
turn is attached to the frame of the machine.
The claims of this patent alleged to be infringed are the second
and third, which read as follows:
"2. Constructed and combined, substantially as herein set forth,
a two-part sleeve, a bearing-box, a row of balls, a serrated
Page 144 U. S. 259
annulus, and a locking button, with an axle and hub and flange,
essentially as shown and described."
"3. The combination, in a ball-bearing device, of a free
bearing-box, G, and a shell case, E, substantially as set
forth."
This patent contains in addition all the substantial features of
the first patent. Neither of them presented any lateral or side
bearing for the bearing-box, its entire bearing being through the
balls, both to support the weight vertically and to resist the
thrust. Both have two sleeves surrounding the axle. In the first
patent, one sleeve was adjustable, while in the other the second
sleeve was also made adjustable, and provided with an annular
flange serrated on its circumference to engage with a locking
button to lock it at any desired adjustment to the flange. A
similar serrated ring, with a corresponding locking device, is
found in the English patent to Monks of 1880, who states that he
employs
"a turned bush, conical at the outer end, and a somewhat similar
one which is screwed upon the outside of the first said bush. In
the V-shaped groove which is formed by these two bushes when in
position, I arrange a series of balls which rotate between the
bushes and the lower part of the fork, which forms a cap, somewhat
circular, with a segmental groove in it for the balls to work in. .
. . The outer end of the bush is formed into a milled or ratchet
head, and is prevented from turning round after adjustment by means
of a pawl fastened to a plate, my object being adjustment in a
simple and efficacious manner when required."
The shell case described in the third claim of this patent seems
to be found in the Salamon bearing patent of 1880, and the Jeffery
patent of 1883, under the latter of which the defendants are
manufacturing. The patent, though issued the same year as the
Wallace patent, antedates it both in respect to the application and
the patent itself. We agree with the conclusion of the court below
that
"with these old devices found in the art, it seems clear to us
that the defendants had the right to use the ball-bearing boxes
which are shown by the proof to have been embodied in their
machine."
It may be said of both of these patents that they are mechanical
adaptations of, or variations from, what had before
Page 144 U. S. 260
been exhibited by the English patents, rather than inventions of
anything essentially novel. They appear to involve such immaterial
changes as would be required to adapt a known device to use in a
combination with other elements, already existing, and such as
would occur to any skilled mechanic. Indeed, the object of these
patents -- and the same remark may be made of all, or nearly all,
involved in these suits -- seems to have been principally to
forestall competition, rather than to obtain the just rewards of an
inventor. It is true the defendants make use of devices similar in
many particulars to those employed by the plaintiff, but they too
seem rather to have adopted prior and known devices and fitted them
to the peculiar construction of their machine, rather than to have
purloined them from the plaintiff.
These cases are not without their difficulties, owing somewhat
to the complicated nature of some of the devices, the number of
anticipating patents, the difficulty of determining how far the
later once are merely colorable variations of the prior ones, and
how far they involve invention, but upon the best consideration we
have been able to give them, we have seen no reason to differ from
the judgment of the court below in its estimate of their value.
The decree of the circuit court is therefore
Affirmed.
