Opinion

BROWN, District Judge.

This suit is for infringement of letters patent No. 535,097, to F. B. Felton, for a “safety device for revolvers,” issued March 5, 1895. Claims 1, 2, and 3 are in issue:

“(1) In a revolver in which the cylinder is arranged to swing laterally outward and inward from and to its recess in the frame, the combination of a holding device to confine the cylinder in its recess, adapted to be operated at will to release the cylinder, and a movable connection between said holding device and the firing mechanism, operated by the movements of said holding device to lock and release the firing mechanism, substantially as set forth.
“(2) In a revolver the combination of a cylinder arranged to swing laterally outward and inward from and to its recess in the frame, a holding device to confine the cylinder in its recess, and adapted to be moved at will to release it, a firing mechanism for said revolver, and a lever arranged between said holding device and said firing mechanism, one end of said lever engaging with said holding device and the other with a movable part of the firing mechanism, and said lever being operated by the movements of said holding device to lock and release the filing mechanism, substantially as and for the purpose set forth.
“(3) In a revolver in which the cylinder is arranged to swing laterally outward and inward from and to its recess in the frame, the combination of a latch on the frame, constructed to confine the cylinder in its recess, and adapted to be moved at will to release it, and a lever, connected with said latch and constructed and arranged to stand in the path of a movable part of the firing mechanism so as to prevent the operation of said firing mechanism when the said latch is in the position to release the cylinder, substantially as and for the purpose set forth.”

The complainant says that this patent “is for a safety device for revolvers of a particular class,” and the specification states:

“My invention relates to an improvement in that class of revolvers in which the cylinder is journaled upon a crane arranged upon an axis below the cylinder, and parallel with the axis of the cylinder, so that the crane and the cylinder may be turned laterally outward from the frame, for loading, or for the ejection of shells.”

The specification further states:

“The object of my invention is to provide such a connection between the cylinder and the lock or firing mechanism that the crane and cylinder cannot [91]*91be turned laterally out of their, normal position in the frame while the lock is cocked, that is, in the firing position, and that, should the lock he cocked when the crane and cylinder have been turned out of the frame, these cannot he returned to their normal position until the lock has been uncocked or brought to its position of rest.”

The complainant contends that this paragraph does not fully set forth the objects or purposes of the invention; and upon its brief says that the primary and important purposes for which the safety device was invented were: First, to lock the firing mechanism simultaneously with the release of the cylinder by the manual operation of a sliding latch, at the will of the operator, so that, whenever the cylinder is unlocked and partially or wholly within the recess and frame, the firing mechanism is inoperative; second, to automatically release the firing mechanism, and automatically lock and center the cylinder simultaneously by the automatic operation of the sliding latch when the cylinder is in the firing position within the recess in the frame, so that, by the automatic operation of locking and centering the cylinder in the firing position, the firing mechanism will be automatically released and be operative.

The Felton safety device is applied to a regular type of Colt revolver, and the firing mechanism and the breech-holding device are shown in Fig. 2 of the prior Ehbets patent, No. 392,503. This revolver is of the well-known side-swing type, in which the cylinder is fixed on a swinging crane, and has lateral movements inward and outward. Revolvers of the prior art have different movements in disengaging the cartridge cylinder from firing position. There are “revolvers with rigid arms and laterally swinging cylinders, in which the barrel and stock are rigidly connected by a frame in which is a recess to receive the cylinder”; “revolvers with cylinders turning sidewise, in which the cylinder is supported on a pivoted arm arranged to turn sidewise”; “revolvers with sliding barrels and cylinders, in which the cylinder slides forward and rearward”; “revolvers with barrels and cylinders swinging sidewise”; “break-down revolvers”; “tip-up revolvers”; “revolvers with cylinders rotating on fixed axes, in which the cylinder has no movement other than the rotating movement.” The prior art also shows breech-loading guns, in which the breech mechanism may be opened to permit the insertion of the cartridges, and in which the breech mechanism may be locked in or released from the firing position by a holding device.

An idea common to various firearms of the prior art, containing the two well-known elements of a firing mechanism and a breech-holding device or bolt, was to combine a safety device with a holding bolt in such a way that the safety device should be moved by the bolt, and should block the movement of the firing mechanism when the breech was not fastened in firing position. It was also old to so arrange the safety device that its movement and the movement of the breech-holding device connected with it were obstructed when the firing mechanism was cocked, thus preventing the locking of the breech when the arm was cocked. The Felton safety device was an application of the familiar idea of a movable connection between the holding bolt and firing mechanism to the Colt revolver, which contained a bolt which locked and centered the cylinder. A pivoted part is so connected with [92]*92this bolt that, when the bolt is retracted and the cylinder released, the safety device is moved by the bolt to engage a stop or pin on the hammer, and, when the cylinder is swung into place and automatically locked, the movement of the bolt being imparted to the safety device causes it to move out of engagement with the stop and to free the firing mechanism.

In applying a safety device to a revolver of any class, the mechanical problem is how to construct it so that the movements of the holding device will lock and unlock the firing mechanism. The broad idea of a safety connection between the holding device and firing mechanism had been so often exemplified in the prior art as to become generic and to contain no novelty.- Examples are the Strong patent, No. 38,944, Hurst & Schultz patent, No. 312,564, both of which relate to breech-loading guns; the Carter British patent, No. 1,820, of 1884, the Wesson patent, No. 429,397, the Mauser patent, No. 213,221, the Moore patent, No. 264,325, the Dimancea British patent, No. 9,973, of 1885, which relate to revolvers.

Regarded as a safety device, it is apparent that Felton’s safety device differs from those of the prior art only in the manner in which the holding device and firing mechanism are combined, and that the scope of the invention cannot be broadened by attributing to Felton any advantages which result from a particular kind of holding device or a particular kind of firing mechanism.
