.ing is n specification.

My invention relates to recoil-actuated firearms, and particularly to that-class of firearms of this description wherein is employed an automatically-actuated rotary cnrtridge-cyh inder.

My primary object is to simplify firearms of this description and overcome certain deficiencies heretofore'existing, particular attention being paid to prevention of undue wear from shock of recoil and to. securing a positive and certain actuation of the csr Midge-cylinder.

A further object is to provide edditionnl safeguards egsinstaccidentel discharge of the weapon.

In the preferred constructionIem ploy si stock or handle, at resiliently-heldrecoil ecr tested reciprocating-frame mounted thereon and which carries the hnrrelsnd certridgecylinder, means for cooking thehsmmer during the recoil or reerward'movement of said frame, and a cylinder-actuating device con nected with said stock and frame and retract ed during the rearward movement of said frame and extended to actuate the cylinder during the return movement of said'fraine."

My-invention is illustrated in its preferred form in the accompanying drawings, showing .lhe invention embodied in a revolver or smell arm.

Said arm projects or is raised above the front wall of .the grip of the handle, so that when the handle is firmly grippedduring aiming the arm N is pressed rearwardly and moves said bell-crankv levers to unlock the trigger; hammer, and sliding frame. a

The handle A is hollow-at the gripping portion to receive the mains'pring and the lower Preferably it.is formed of the part 1), (shown in Fig. 4,) upon which partthe sliding frame P is mounted and'which part is provided with a downward extension. p, Fig. 2, which forms the front wan of the hollow handlda part 37 formingthebottom and rear walls of the handle and detachnbly connected with the part 0' b screws 8 the part p being'provided at its upper end with a ,liousing 10 which receives therear portion of theframe B during the recoil, and side plates 1119"; whichconform to 'theoutline of the metallic portion-ofl the grip of the handle and are detnchably connectedtogether with a screw p As's'hown in Figs. 2;3l and 8 particularly the housing p has between its sides a recess 10 for rec'eiving'the rear end of the frame B during the recoil, and at the base of said recess are lngs'p oneof which, niiords at its forwsrd end a shoulder p for exception of s p-pears in "engaged by the shoulder sadjacent thereto-- ated as stated.

The only portion of this device which the'drawings is 2. lug s, which is when theirame is disengaged from the rearward extensionof the-barrel o and swung by its pivotal point to eject the shells.

The gtrigger extension is provided with a forward projection v, which bears upon the adjacent portion of the trigger-guard, and at w an enlargement o'.,

an enlargement v .on the forthe pivotal point g? is which engages ward portion of the lever H during the forward movement of'the frame B, thereby unlocking the cylinder. During the return movement oi the frame the cylinder is actucomplished .by onehaving a reasonable knowledge of the art, and assuming the-cylinder tohave lts'cha'mbers charged with cartridges, it is only necessary to grip the revolver. in the usual manner to hold the same otal point, therehy moving the hell crank levers L M and nnloclging thetrigger exno I tension,the hammer extension, and the slidingframe, as heretofore explained. Vhen a cartridge is discharged by operating the trigger in the usual manner, the recoil-action forces the frame B and the barrel and cylindersnpported thereon rearwardly, compressing the main spring K. During the rearward movement the hammer extension E encounters the lug 11 with which thehandle is equipped,thei-eby moving the hammet to the cocked position, where it is engaged by the sear, a spring t (shown in Fig. 2) serving'to actuate said sear. After the re coil the frame is restored from its retracted position to its advanced position by the mainspring K, acting through the medium of the links K K and hammer E. During the rear ward movem entof the frame the link'J of the cylinder-actuating device is carried with said frame and is caused by its engagement with the pin j to swing downwardly about its pivotal' point 3'. This depresses or retracts the pawl l (spring-held by a spring t) to bring the name into engagement with a new tooth on the ratchet-wheel (1 During the. restoring movement of the frame the link J .is again swung upwardly, thereby causing the pawl I to actuate the cylinder.

It will be observed that owing to the connections between the cylinder-actuating device with the frame and handle said device is so constrained as to be positively depressed or retracted duriug the rearward movement of said frame and to be positively extended or restored to its former position during the forward movement of said frame. It thusappears that the mains'pring serves through the medium described to actuate the cylinder during the restoring movement of the main frame.

' Changes in details of construction within the spirit of my invention may be made by those skilled in the art. Hence no limitation is to be understood from the foregoiug'detailed description except as shall appear from the appendcdclaims. Forinstance,thecylinderactuating device may be variously modified and connected with the frame and handle to secure the positive action indicated, the

inainspring still serving through its medium to actuate the cylinder.
