Mr. Justice Brown delivered the opinion of the court:

The bill in this case, in addition to the usual allegations of a bill for the infringement of a patent, sets forth as a distinct ground for recovery the violation of the contract of December 1, 1884, which it was claimed was obligatory upon the defendants. As this claim was. however, disposed of in the cases Nos. 204 and 205, just decided adversely to the plaintiff, upon grounds which are equally available here, we shall take no further notice of it.

the infringement of a patent.

(1) Patent No. 252280, to Curtis H. Veeder, is for a "seat for bicycles." In his specification the patentee states that his "improvements relate to the class of seats known as saddles,' and especially to devices for suspending the leather or other flexible material of which the

But as Veeder's connecting the same with the perch or support-invention, in view of the state of the art, is a ing bar for the seat, and by means of which | very narrow one, we think it cannot be propthe seat is made adjustable backward and for- erly considered as covering the defendant's deward over the perch or bar; and my present vice.

The feature of extensiframework for the rear of the seat; third, in bility does not pertain at all to the springs, but mechanism for elongating or extending said to the peculiar manner in which the rear spring metallic spring so as to take up the slack of the is adjusted to the perch. If Veeder had been flexible seat; and fourth, in mechanism for the first to invent a saddle supported upon completing the support of the seat and con- springs, or a flexible spring seat capable of adnecting the same with the perch or supporting. justment, it might be thought that the defend. bar of the vehicle, so as to be adjustable back-ants could be held to infringe, though they do ward and forward thereon."

He further states that he is aware "that a spring has been used to support the seat or saddle of a bicycle," and, therefore, does not claim the general application of a spring for this purpose, but does claim:

་་

"1. A suspension saddle, constructed with a flexible portion C, and having an under spring in two or more parts, B D, to which the flexible portion is attached at either end, and which metallic parts are extensible, substantially as and for the purposes set forth.

2. In a velocipede seat, the combination of plates B and D, clamp F, stop b, adjusting bolt F, substantially as shown and described." Referring to the state of the art, as disclosed by prior patents, there appears in the patent of John C. Miller, of April 10, 1866, a saddle seat suspended at both ends upon springs; the seat, however, has a framework of iron, and consequently is not flexible, and, of course, has no provision for taking up the slack. In the patent to Fowler of 1880, there is a saddle seat, suspended, at the front end, upon a coil spring, and at the rear end upon a long plate spring; the seat is rigid, however, and lacks the flexibility which characterizes the Veeder patent, and there was apparently no provision for mutual adjustment of the springs. The Shire patent of 1879 has a flexible saddle seat, the front end of which is attached to a strap which passes through a loop, and is susceptible of being shortened or lengthened by means of a buckle. It also has an under spring to which is attached the forward end of the flexible saddle. It differs principally from the Veeder patent in the fact that the slack is taken up by means of a strap and buckle, instead of by au adjustment of the two springs of the Veeder patent. The Bishop patent of 1859 exhibits a flexible seat suspended upon springs at either end, but it also lacks the adjustable feature.

None of these prior patents exhibit a flexible seat supported at either end by two parts of a spring, which are made adjustable relatively to each other, in such manner as to take up the slack; and for the purposes of this case [242] it may be conceded that there was invention in this device, notwithstanding that other patents showed flexible seats suspended upon springs at either end, and in some cases with the feature of adjustability. The Veeder patent, how ever, differs no more from the prior patents than do the defendant's saddles from it. In the defendants' Champion saddle a flexible saddle is supported at either end upon springs, the rear one being made adjustable in such a

not employ the double spring of the Veeder patent, but in view of the state of the art, we think the court below was correct in holding that there was no infringement.

(2) Patent No. 197289 to the Peters is for an "improvement in anti friction journal-boxes" for overcoming the friction of the bearing of all vehicles mounted on wheels, and the journals of all revolving shafts, etc. The invention is "a combination of rollers or cylinders, made of iron, steel, or any suitable metal or other material, of sufficient number and suitable in length, size, and form, which revolve around the spindle or bearing of the axle within the hub of the wheel, and around the journal or bearing of the shaft or cylinder, and within the journal box, the rollers being independent of the bearing and the hub or journal box."

The only claim in issue in the case is the second, which is for "the bearings with the shoulder beveled or notched, combined with the nut, or its equivalent, correspondingly beveled or notched, as shown in figure 4."

This patent is in substance for a method of overcoming the friction of an ordinary journal by causing the same to revolve upon elongated: [243] rollers, whose action is guided and secured by putting them in a cage, so that their relative relations to each other in their revolution shall be the same. "To support and keep the rollers from running against one another and thereby producing friction, both ends of each are made with a bearing, which goes into rings, or their equivalents, in such a manner as to allow the rollers to turn freely on their bearings as they revolve around the bearing of the axle or shaft. These rings may be flat, or one or Loth sides rounding or oval, and of one entire piece, or made in sections or parts, and the parts fitted or hinged together in such a manner as to form the required ring." "To retain the wheel on the bearing of the axle, as the wheel of a common road vehicle, the ordinary nut in use for that purpose, or its equivalent, is made to bevel in conformity with the beveled ends of the rollers, and the bearing or axle at the inner ends of the rollers is made with a beveled shoulder to correspond with the ends of rollers."

The patent to Allcott, of March 29, 1870, has also for its "object the diminution of friction in ordinary axle boxes, and consists in constructing the hub box larger than the journal of the axle, and filling the space between the journal and the box with longitudinal metallic rollers, of which two sizes are employed, the

larger and smaller alternating, and more com
pletely filling said space." The axle is formed
with a grooved flange and the journal with a
similarly grooved or beveled nut. The ends
of the rollers are also somewhat beveled to cor-fringement of the prior ball bearing patents.
respond with the tapering portions of the jour-
nal and nut. When the beveled ends of the
rollers become worn down the beveled sleeve
on the nut may be filed down, and the nut
screwed up, thus keeping the rollers from any
longitudinal motion.

of the spherical balls of the Chinnock, Jewett,
and other patents, it would seem to follow that,
if its device be an infringement of the Peters'
patent, the Peters' patent itself must be an in-

This patent seems to be very nearly, if not quite, a complete anticipation of the Peters patent. Such differences as exist between them are of minor consequence; the beveled [244] shoulder combined with the beveled nut or its equivalent being present in, and the essential feature of, both patents. In any view of the case it required no invention to make the slight alterations apparent in the Peters patent.

(3) The Moran patent, No. 245542, of August 9, 1881, is for a handle for velocipedes, and consists simply in providing rubber han. dles for counteracting the jar on the hands in traveling, and preventing injury to the machine when falling. The claims are:

"1. The handle of a velocipede provided with rubber ends, as set forth.

"2. The handle of a velocipede, in combination with rubber tips sleeved upon its ends, as set forth.

"3. A rubber handle for a velocipede, consisting of a ball and neck combined in one piece, as set forth."

Briefly stated, this patent is for nothing In addition to this, however, the Jewett more nor less than the application of a rubber patent of May, 1868, shows "a journal or axle ball or cushion upon the extremities of the box, provided with a series of spherical balls, handle. The patentee states in his specificawhich are placed in a circular recess or cham- tion that bely claims this rubber in its ap ber, and revolve in contact with the journal or plication to velocipedes, it being a not uncom axle, thereby reducing the friction to a great mon device as applied to other handles. We extent, and entirely avoiding the necessity of have very grave doubt as to whether this inemploying oil or other lubricating material."volves any invention; but if it does, it is fully The grooves of this tent at the opposite ends anticipated in the English patent to Harrison, of the axles are practically the same in their of July, 1877, which exhibits a similar method operation as the beveled shoulder and nut of of covering the handles of bicycles with a the Peters patent, the balls giving both vertical sheath or glove of india-rubber. There is a and lateral support, and preventing end wise slight difference in the form of the sheath in movements. Similar arrangements are shown this case, but it is identical in principle, and in the patent to Perley of 1863, and the Eng- used for the same purpose. Indeed, the delish patent to Mennons of 1860. fendant in this connection seems to rely not upon the validity of his patent, but upon the estoppel alleged to have arisen under the contract of 1884, which we have already held not to exist.

There was also a patent issued to one Smith upon the same day the Peters' patent was issued, namely, November 20, 1877. but upon an application filed September 1, 1877, prior to Peters' application, and, therefore, anticipating Peters' patent, in which was represented an axle formed with a spindle, having a collar at its inner end, in which collar was a circumferential half round groove. The outer end of this spindle is reduced in circumference, and another collar is placed thereon and fastened by a screw, this collar being also provided with a similar groove. In each collar is placed a series of anti-friction balls, which are of such diameter as to be one half within the groove in the collar. The other half of the ball is within a groove formed one half in the hub and the other half in the flange upon an annular plate. The operation of this patent is practically the same as that of the device used by the defend

ant.

This device appears to be, however, a minor variation upon the English provisional specification of 1853 to Chinnock, which also consisted in securing the axle in the box by means of one or more spherical balls running in a circular channel, formed partly in the axle and partly in the box in which it fits. Defendants are the owners of and manufacturing under this patent, and the fact that this and the Peters' applications were pending before the Patent [245] Office at the same time, and that patents were issued upon the same day, is strong evidence that they were not even considered as competitive inventions.

As the defendants' manufacture was not of the elongated rollers of the Peters' patent, but

(4) Patent No. 310776, to Benham is for a method of attaching the horizontal handle bar to the steering bead of a bicycle, and consists in making the handle bar, which may be either solid or tubular, continuous, and attaching to the middle of it a lug or detent, which serves not only to locate the handle bar evenly and quickly by an even division of its length on either side of the middle line of the head, but also to prevent the handle bar when in position from turning or revolving on its axis. The first and third claims of the patent, which are alleged to be infringed, are as follows:

[ocr errors]

"1. The combination of an undivided and an open-slotted lug, and two sleeve-nuts, or their equivalents, one on either side the lug, surrounding the bar and adapted to lock it rigidly to the lug, essentially as set forth."

3. In combination with the handle bar B, the detent D, constructed and adapted to oper ate substantially as and for the purposes set forth."

The patent is really for making the handlebar in one piece and so attaching it to the steering head of the bicycle so as to prevent any lateral or rotary movement. This is done by the use of sleeve-nuts surrounding the handle bar and engaging with threaded portions of a lug, through which the bar is thrust.

If there be any scope for invention in the attachment of a horizontal bar to a vertical one in such manner that it shall be firm aud immovable in any direction, t. is device ap

[24

there is no novelty in the particular shape in [248}
which these rubber coverings are made, or the
form which the corrugations or groovings shall
take; it is a mere matter of taste or mechanical
skill.

If there be any novelty at all in the Latta
patent it must receive such an exceedingly
narrow construction that the defendant cannot
be held to have infringed it.

pears to have been substantially anticipated by | vent slipping being once conceded to be old,
the English patent to Illston, issued in 1879,
which shows substantially the same elements
operating for the same purpose, and in sub-
stautially the same manner. Illston states that
he makes "near the top of the head of the bi-
cycle or tricy cle a cross hollow bracket open
at its ends and top," corresponding to the
open slotted lug of the Benham patent. "The
said bracket has externally a nearly cylindrical
figure, and its ends are furnished with convex
screws.
On each side of the middle
flattened part of the handle bar is a sliding col-
lar milled externally, and screwed internally
with a concave screw proper to fit on the con-
vex screw at the end of the hollow or trough
bracket on the head." The screw collars of
this patent correspond very closely with the
sleeve nuts of the Benham patent.

Upon the whole, it does not seem to us that there was any patentable difference between

In short, the patents, which are made the basis of this bill are, in view of the state of the art, all of them of a trivial character, and, so far as they possess any merit at all, are not infringed by the devices employed by the defendant.

The decree of the court below dismissing the bill is therefore affirmed.

these two devices, and if there were, we agree THE POPE MANUFACTURING COM. with the opinion of the court below, that it is certainly not infringed by the defendants, [247] who, while they use an undivided handle bar, have adopted a different method for fastening the same to the steering bead, and do not use either the compiainaut's open slotted lug and two sleeve nuts or their detent

(5) Patent No. 323162, of July 28, 1885, to
Emmit G. Latta, relates to a form of protect-
ing or cushioning the pedals of a velocipede
with india rubber. There are eight claims to
this patent, the second and third only of 1.
which are alleged to be infringed. They are
as follows:

2. The combination, with the pedal frame,
of a rubber pedal bar, H, provided with a cen-
tral lougitudinal grove, h, and two bearing-
surfaces, h, on opposite sides of the groove,
h, substantially as set forth.

3. The combination, with the pedal frame, of a rubber pedal bar, H, pivoted to the frame by a rod, i, and provided on each of its sides with a longitudinal groove, h, and two bearing faces, h', on opposite sides of the groove, whereby the bar, H, is adapted to receive the pressure at its sides or edges and be compressed on opposite sides of the rod, i, substantially as set forth."

The invention in these claims consists in the pedal bar, combined with the pedal frame, the pecial bar being rubber, constructed with grooves and bearing faces; the second claim providing for the bar being pivoted to the frame, so that it works easily either side up, and will turn on its bearings as the foot presses on the front face or the rear face of the pedal. The pedal is centrally grooved and has two bearing faces, one on each side of the centerrod on which it is pivoted.

feet on the pedais. This rubber is made cor-

upon the pedals as the ordinary smooth surface
rubber had been placed. The English patent

4. Any assignment or transfer, short of the whole patent or of the exclusive right in a specified territory or of an undivided part of the exclusive right, is a mere license, which gives the licensee no title in the patent, and no right to sue at law in his own name for an infringement. 5. An assignment of all the patentee's right, title and interest in and to certain letters patent on velocipedes, so far as said patent relates to or covers the adjustable hammock seat or saddle, which is the second claim of the patent, except the right to use said seat or saddle in connection with the velocipede made by the assignor, is a mere license and does not vest in the assignee or his assigns the legal title to the second claim nor the right to sue in his own name upon it. 6.

Statement by Mr. Justice Brown: This was a bill in equity for the infringe. ment of two letters patent, namely, No. 216 231, issued to John Shire, June 3, 1879, for an improvement in velocipedes, and, second, pat ent No. 314142, issued March 17, 1885, to Thomas J. Kirkpatrick, for a bicycle saddle. Both patents were contested by the defend ants upon the grounds of their invalidity and non-infringement, and in addition thereto it was insisted that plaintiff had no title to the [249] Shire patent.

claims, & se covers, not only the adjustable hammock seat mentioned in the second claim, but three combinations set forth in other claims, of which the hammock seat is an element in only one.

Did this instrument, then, vest in Kirkpatrick the legal title to that element in the patent embodied in the second claim, or was this a mere license, giving him a right to make, use, and sell the device in this claim, but not vesting in him the legal title, or enabling him to sue thereon in his own name, really involves the question, which is one of nor to convey such right to the plaintiff?
