52 F. 147 | U.S. Circuit Court for the District of Massachusetts | 1892
The present suit is for the infringement of letters patent No. 384,898, issued June 19, 1888, to the complainants, as assignees of James C. Cutcheon. The patent is for an improvement in beating-out machines. These machines are used to give the sole of a shoe the requisite curve or contour. Originally this was done by the cobbler holding the shoe between his knees, and beating the sole with a flat-faced hammer. In the operation of these beating-out machines three motions are necessary,—the motion of pressure, the motion of clearance, and the motion of removal. The first machine of this character was constructed under the Johnson patent of November 26, 1867. This apparatus consisted of a hand-operated screw press, in which the sole of the shoe was forced against a mold or base plate having the proper curvature to give the sole the desired shape. This was followed by the Johnson patent of March 10, 1868. In this device the shoe was supported upon an iron last, mounted upon a bar moving vertically between the guide to and from a fixed mold. The last was connected with a toggle lever, and a foot lever, and the operator, by placing his foot upon the foot lever, forced up the last against the mold. The next Johnson patent is dated July 22, 1873, in which the machine was operated by a power driving shaft, so that when the operator had pressed the treadle down part way the power of the shaft would force the sole against the mold. In his patent of June 30, 1874, the same inventor substitutes a jack for the iron last or shoe carrier. This jack was adapted to carry several sizes of wooden lasts, whereas, in the case of the iron last, a separate last must be provided for each size of shoe. The next improvement of Johnson was patented July 20, 1880. In place of a single pressing mechanism, this machine contains a number of such mechanisms arranged side by side, and for this reason it became known in the art as a “gang” machine. The next patent referred to in the record was granted to Maurice V. Bresnahan, June 10, 1884. This was also a “gang” machine. In this device the motions are horizontal, instead of vertical, as in previous machines. It is unnecessary to enter into the specific improvements embraced in this machine.
The result of this brief review of the prior art shows that, previous to the Cutcheon patent, the operation of clearing the last from the die had never been done automatically. The essence of the Cutcheon invention is that it was the first machine in which both the motions of compressing the last and of clearing the last from the die were performed automatically. The first claim of the patent is as follows:
*149 “A machine for beating out the soles of boots and shoes, provided with two jacks, two molds, and means, substantially as described, having provision for automatically moving one jack in one direction while the other is being moved in the opposite direction, whereby the sole of the shoe upon one jack will be under pressure, while the other jack will be in a convenient position for the removal of the shoe therefrom. ”
There is no doubt that the defendants’ machine contains all the mechanical elements embraced in the above claim. The fact that the defendants use lasts instead of jacks in their machines is unimportant, because they are well-known equivalents. Upon the question of alleged prior use of the Cutcheon invention several years before the date of the patent, in a single machine constructed mainly in accordance with the -Bresnahan patent of June 10, 1884, I am satisfied that this defense has not been made out upon the present record.
The defendants are also charged with infringing the third claim of the patent in suit, which relates to certain details of construction. This claim seems to have been anticipated by the old style Knox molder, but the defendants have not proved the use of the old Knox machine prior to the date of the Cutcheon patent. Upon the evidence, therefore, I must hold that this claim is also infringed. Decree for complainants.
