. [Bait known that I," SAMUEL (13 m, a

subject of Russia, and a resident of clifilfio' n. he. oun y Of u l a d mma-g of Massachusetts, have, invented etitain newand useful Improvements in Gun Firing Mechanisms, of which the following a specification.

This invention relates to devices or oper;

firing mechanisms of firearms has for ts; object the provlsion of means for.

operating the firing mechanism of a s firearm at predetermined times.

The invention consists of a firearm prefersecuredtoa framework a fixed posifltion and a motor. controlled endless chain member 11 being adapted to exten mped. s cefitimiofis mov m nt in at d rectlontqrotatea crankhavlng a Inern;

beripiuoted thereto and reeiprocable bydthe rotation thereof, the free end of which so ceg acts with the trigger of the firearm that the-latter. will be fired at each rotation of said crank.

Theinvention further consists in certain novel features of construction and arrangement of parts which will be fully understood by reference to the, description of the throughout the several figures of the draw- Til the drawings, 10 is a firearm herein shown as a revolver of the self-cocking type, the barrel of which has secured thereto a supplemental tubular member 11 shaped like the chase of a large caliber un, this (1 through the port of a turret or similar member.

The revolver or firearm 10 is provided with the usual cylinder 12 adapted to receive cartridges and said cylinder 12 is rotated in the usual manner whenever this hammer 13 is cocked.

The hammer 13 is cocked by means of the member '14 pivoted at 15 and having the trigger arm 16 formed, integral therewith.

A spring 32 connects the arm 16 to the link 27, said spring insuring the return of the trigger 16 to its normal position after each operation of the firing mechanism.

- The revoluble shaft 29 has secured to its lower end a sprocket wheel 33 the teeth of which mesh with an endless chain 34 supported upon the wheels 35, 36, and 37.

The wheel 35 is secured to and rotates with the shaft 38 of a motor 39 shown in the drawings as an electric motor in a circuit 40 provided with a battery ll and a switch 12. When the switch 42 is on, the motor 4C0 will drive the chain 3 1 in the direction indicated by the arrow 6.

The firearm 10 is rigidly secured by the bolts 44: to the bracket 45 secured to the frame 31. The rotation of the crank 28 will cause the link 27 to move the trigger arm 16 to the left of Figs. 1 and 2, and

thereby cause the hammer to be cocked and then released as hGIfetOfOIG s d- The' device, is particularly pplieaue to toy battleships in which it isdesiredthat the guns protruding from the various turj rets should be fired at' predetermined times.

' It is obvious. that when the chain ismo-vingthe continued rotation of the crank will cause: the firing ofthe revolver until-the last cartridge in the cylinder-is exploded, f

It islbelieved that the construction and operation .Will be fully, understood from the I foregoing description. f
