Opinion

BLATCHFOBD, District Judge.

This suit is brought on reissued letters patent granted to the plaintiff, March 9th, 1809, for an “improvement in cushions for billiard tables,” the original patent having been granted to him December 18th, 1SGG. The specification of the reissued patent says: “My invention has for its object the preservation of cushions for billiard tables against the impact of the ball. The nature of my invention consists in the employment or use of a catgut or other strong cord, located in or at the upper comer or edge of the cushion, and immediately at the point against which the ball strikes when the .game of billiards is played. * * * C is a body of rubber, which formsacushionagainstwh.ch ' the ball strikes. This said rubber cushion has its inner or face side bevelled in such a manner that the ball strikes, at about its centre, against the upper corner or point of the cushion, as clearly shown at a, Fig. 1. For the purpose of protecting the upper corner or

[330]*330edge of the cushion, C, against the impact of the ball, I make a small concave or bed, immediately, or as near as may be, in the upper corner of the cushion, so that a suitable cord, E, or other support, may be fitted longitudinally the whole length of the said cushion, around the table, so that the cushion is fully protected, on all sides of the table, against the impact of the ball. Por this cord and support of the cushion I usually employ catgut, or cord may be used for the same purpose, but experience proves that catgut is most suitable for the purpose, as it is best adapted to prevent the cushion from giving way, or yielding, under the impact of the ball, it being understood that the ball only comes in contact with the cushion at a, the bevel or inclination being given the face of the cushion in order that all other parts of it will be kept clear of the ball. This cord, E, may be more thoroughly secured in its position by moulding it, or embedding it, entirely within the rubber, near the comer, so as to perform the functions for which it is designed, or it may be secured by gluing a strip of doth, b, over it, when not fully embedded in the rubber, or It may be secured by any other well-known means. I) is a strip of elastic cloth, which is cemented to the face side of the rubber strip or cushion, C, and attached, at its lower edge, to the lower part of B,” (elsewhere described as a strip or cleat, behind C,) “so as to support the upper edge, a, of C. It will be understood, that the cord, E, is attached to D, before the latter is secured to the cushion, C, and deat, B. To make the whole more secure, I usually cover the whole with the cloth, F, and after cover the whole again with the usual green doth, G. This cord, E, performs two very important functions, viz.: it gives stiffness to the angle or corner, a, of the cushion O, so that it cannot yield or give way under the impact of the ball, to allow the latter to pass over it; and it also gives prominence to the said angle, so as to present, under the yielding of the cushion, a stiff, narrow line to the ball, thus obviating much friction, so as not to impede the motion of the latter, and still not interfering in the least with the elastic effects of the cushion upon the ball.” The claim is in these words: “The catgut or other cord, E, partially or fully embedded, or otherwise attached, at the angle, a, of the rubber cushion, C, so as to'protect said cushion against the impact of the ball, substantially as herein shown and described, and for the purposes set forth.”

It is quite apparent, that the invention set forth is the placing, and firmly securing, along the upper edge or corner of the rubber cushion, a strong, narrow cord, to receive the impact of the ball, and protect the cushion against such impact, by reason of its being placed at the point against which, and against which alone, the ball strikes. When the impact comes, the stiff cord receives it, in substantially a horizontal direction, and prevents the cushion from giving way under such impact, and allowing the ball to ride over it and leave the table, while, at the same time, there is little friction from the impact, and the elastic force of the rubber acts fully, through, the cord, interposed between it and the ball, to repel the ball, in substantially a horizontal direction.

The great utility of the invention, in tending towards perfection in the billiard table, is shown by the evidence. The inventor was an experienced mr "-ifacturerof billiard tables. The cushion had, up to the time of his invention, in the latter part of 1864, been faced with a fiat facing, made of various materials. But, the flat facing failed to add the necessary greater proportional strength to the upper corner or edge, and the plaintiff sought to do that, while, at the same time, the rubber below the edge, not being faced, would have its elastic action left unimpaired. The idea of a cord of catgut, to be secured to the upper edge, suggested itself to him. He arranged it, in the manner described in the specification of the reissue, and shown in the drawing, by laying the catgut along the edge of the elastic cloth which he had been using as a facing, and securing it there by wrapping a piece of doth around it, and attaching that to the elastic cloth, and cementing the latter to the rubber. The moment the invention became known, it went extensively into use, and the cushion thus made superseded all other forms. A resulting feature of the arrangement is shown by the evidence to bo, that a larger amount of the elasticity of the cushion is brought to bear at the point of contact of the ball with the cord, than when, in the absence of the cord, the ball strikes the rubber itself. The cushion is, also, protected from wear. Greater accuracy, also, results in respect to the direction the ball takes in rebounding.

In the defendants’ arrangement the cord is embedded in the rubber cushion at the upper edge of it, and is secured there by being placed in it while the rubber is plastic, and before it is vulcanized, and by having a thin portion of the rubber interposed between the cord and the outside of the edge. There is no doubt that the defendants’ arrangement embodies the invention claimed in the plaintiff’s reissued patent, and has the same mode of operation, in use.

The novelty of the invention is attacked, by referenced» an application filed in the patent office, January 18th, 1858, by William B. Carpenter, for a patent for an “improvement in billiard cushions,” and which was rejected April 10th, 1858. The specification filed by Carpenter says: “The nature of my invention consists in providing a block of India rubber, cut or moulded in the desired shape, with a groove, which groove is to be made along the entire upper and outer edge, in which groove is to be placed a wire, composed of whalebone, steel, brass, or other elastic material, suitable for the purpose.” Carpenter then proceeds to say, in the specification, that [331]*331he makes a groove at the outer, and along the entire upper, edge of the rubber, and inserts in the groove,- along its length, a round piece, the size of the groove, of whalebone or steel or brass wire. The drawing shows the wire lying in the groove, and not otherwise secured, and with its upper face exposed to view. The specification says, that the cushion is to be “covered with doth, in the usual manner of billiard cushions,” and is then ready to be used.
