Opinion

TOWNSEND, District Judge.

This is a suit charging infringement of claims 1, 2, and 4 of reissue patent No. 11,216, dated December 29, 1891, and claims 1 and 2, being all the claims, of patent No. 466,532, dated .January 5, 1892, both of said patents having béen issued to William E. Bartlett for improvements in bicycle tires. The defendants are purchasers from the Gormully & Jeffery Manufacturing Company, of Chicago, which has assumed the defense of this action. '

Said claims are as follows:

Patent No. 11,216.
“(1) A wheel having a vulcanized India rubber tire of cylindrical form when free, and without joint after vulcanization, and held upon the wheel in a form trough-like in section, and there retained by inwardly inclined flanges upon the wheel.
“(2) A wheel having a rim formed with inwardly inclined flanges, and a vulcanized India rubber tire without joint formed from a cylinder of rubber bent .and held upon the wheel in a trough-like form.”
“(4) A wheel rim provided with outwardly convergent side flanges, an annular inflatable tube seated in said wheel rim, and a rubber tire of arched form in cross section, and embracing the convex portion of said annular tube, and having its edges inclosed between said flanges and the opposite sides of said annular tube, respectively, substantially as shown and described.”
Patent No. 466,532.
“(1) The combination, as herein set forth, of a wheel rim provided with an exterior groove and with convergent side flanges, an Annular tube of flexible material seated in the said groove, an annular U-shaped rubber the surrounding-and embracing the convex portion of said tube, with its edges adapted to be seated in the undercut recesses afforded by the said inwardly converging side flanges, and reinforcing ribs for insuring the close confinement of the inclosed edges of the tire in the said recesses by the inflation of the said tube.
“(2) The combination, as and for the purposes herein set forth, of the wheel rim, A, provided with the inwardly converging side flanges, a and a*, the annular tube, B, and the amular tire, 0, constructed with the integral reinforcing ribs, Oi, and 02.”

Defendants deny infringement of any of said claims, and deny complainant’s right to bring suit on either of these patents at the time of the commencement of the action. They contend that the fourth claim of reissue patent No. 11,216 is invalid because of anticipation, and because the invention claimed therein is not in any way indicated or attempted to be secured in the original patent. They further contend that patent No. 4-66,532 is anticipated, and does not disclose any invention in addition to that contained in patent No. 11,216.

The application for the original patent, No. 448,793, of which No. 11,2Í6 is the reissue, was filed November 18, 1890. The invention there described was a wheel with flanges on the rim, converging inwardly, and a cushion tire, consisting of a flat endless band of India rubber broader than the space between the base of the wheel rim, adapted to be secured within the converging flanges by bending the edges together and placing them there, the elastic force of the rubber being sufficient to hold the edges of the band firmly against the flanges of the wheel, and the pressure upon that part of the band which at any time touched the ground while in motion increasing the pressure against the flanges at that point, and thus holding the tire all the more securely.

[453]*453All of Bartlett’s original claims were at first rejected in the patent office. In a letter to the office he then defined his position as follows :

“Tho leading feature of this invention is that the India rubber tire forms an arch which is prevented from flattening under pressure of the load simply by the support afforded it by a trough-like felly, against the sides of which the arch abuts. The sectional form of the tire is rectangular, and that of the felly is trough-like, with inwardly inclined sides. The tire is sprung into place as is shown in Fig. 5. It will be seen that the pressure of the load of the wheel gives rise to an outward thrust exerted by the edges of the tire against the side, or inwardly inclined edges, of the trough-like felly. This is an essential feature.”

Mgs. 7 and 8 of the original drawings show means for supporting this tire, one by a roll of sponge rubber, and one by a tube to be filled with compressed air. It was stated in (lie patent that such supports might be used, and that in such case the rubber hand might be made thinner.

In the history of the art of rubber bicycle tires three distinct types have successively been developed, known, respectively, as the “solid,” “cushion,” and “pneumatic” tire. The narrow surface of the solid tire slightly relieved the shocks encountered in practical use. The cushion tire was hollowed out in its center, and for this reason afforded a much more elastic support to the rider. The advantages derived from each of these constructions were due to the resiliency of the rubber tire itself. The pneumatic tire, although it is constructed, in part at least, of rubber, and although it presents to a marked degree the feature of resiliency, depends therefor not upon the resiliency of rubber, but upon the resiliency of the air with which it is inflated. In fact, the ordinary external covering of rubber and doth is practically devoid of resiliency, and the elasticity of the rubber is only incidentally made available in connection with the capacity of the rubber to retain the highly-compressed air, which air by its activity furnishes the highest degree of resiliency. It is important to hear in mind this well-recognized distinction, because it Fes at Hie foundation of the issues herein involved.

T1Ü» patent was clearly for a cushion tire, the tube filled with air or a roll of sponge rubber being intended morel v 1o support and increase the activity of said rubber cushion tire, which was (he principal fea hire. In his English patent, No. 16,348, for substantially the same invention, the provisional specification of which was filed October 14, 1890, and the complete specification filed July 13, 1891, and allowed August 15, 1891, (here is no mention of any such supports for the rubber band or tire, and no indica! ion of them in the drawings. The application for the reissue was filed October 22, 1891. The application for No. 466,532 was filed September 26, 1891. So far as the rim of the wheel and the flanges and the shape of the rubber tire are concerned, the drawings do not differ substantially from, those in the original application, the drawings of the rubber tire in No. 466.532 being perhaps slightly thinner than in the other drawings. The inflatable tube, however, as shown in these drawing's of the reissue, completely fills the space between the rubber tire and the trough of the wheel, and touches, or very nearly touches, the whole of the inner edge of the rubber tire, as it did not in the orig[454]*454inal patent. In patent No. 466,532 the-flanges are a little more convergent than in the former tire, which enables ribs or reinforcers to be added to the rubber tire, so that the edges of the rubber tire would seem to be held a little more firmly, and the inflatable tube everywhere touches the rubber tire. Defendants’ wheel has a shallow flattened rim, thus differing from complainant’s wheel, in which the trough of the wheel is comparatively deep.
