9 Claims.

This invention relates to improvements in toy pistols, and particularly that type of toy pistol which embodies machine gun elements, and has for its object to provide means for supporting a strip of ammunition, and means continually operating to fire said strip of ammunition.

It is an object of this invention to provide, in connection with a toy pistol adapted to use a strip of ammunition, means for supporting the strip in a roll form, means constituting an anvil for feeding the strip, and means operated by the anvil as it rotates for causing the hammer to strike the strip of ammunition on the anvil.

It is an object of this invention to provide, in

connection with an anvil and a hammer for firing the strip of ammunition, means for continually feeding and firing said strip, said means comprising a means for applying power to the shaft for rotating it.

It is also an object to provide, in connection with an anvil and a hammer, means for rotating the anvil and causing the hammer to strike the anvil, said means including a shaft connected to the anvil by means of a pawl and ratchet mechanism, means for operating the shaft, and means for retarding the rotation of the shaft for the operation of the hammer and anvil.

These and other objects and advantages will appear from the following description taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a side elevational of the complete pistol.

Figure 2 is a side elevation of the operating mechanism located within a casing forming part of the' body of the pistol.

Figure 3 is a top plan view of the mechanism shown in Figure 2, and showing the hammer and drum in their positions just before the drum begins its operation on the hammer.

Figure 4 is a view similar to Figure 3 but showing the drum and the hammer in their positions just before fixing.

Figure 5 is a section on the line 5-5 of Figure 3.

Figure-6 is a section on the line 6-6 of Figure 2.

Figure 'l is a bottom plan view of the drum, showing the spring and pawl and ratchet mecha nism in their operative relation therein.

The form of the pistol is shown in Figure 1, which shows the pistol to have the usual butt I, casing 2, and a barrel member 3. The casing is adapted to receive andv contain the operating mechanism, such as that disclosed in Figures 2 and 3. The operating mechanism is supported on and includes a plate 4, which constitutes a support, one end of which engages the rear 5 of the-casing. Beneath the plate, which is rectangular in shape, there is a frame which has an upper member 6 attached to the plate, a lower 5 member l and an intermediate member 8. These three

members

6, 1, and 8 are attached to one another at their rear ends by means of an end member 9. The front end of the part 6 is attached to the intermediate part 8 by means of an 10 end member I0, while the front ends of the parts g an?.I 8 are connected by-means of a front mem- The frame formed by these various parts and members forms two cavities, an upper one and a 15 lower one. Extending through the frame and these cavities is a shaft I2, which has on its upper end an operating handle I3 pivoted to a sleeve 32. In the upper cavity and around the shaft is a coil spring I4, which has one end attached to 20 the shaft, while its other end is attached to the part 9 of the frame.

Between the intermediate member andthe lower member is a train of gears comprising a gear I5 mounted upon the shaft I2 and provided 25 with a hub I6, a gear 22 integral with a pinion 2 I, which meshes with the gear I5 and is mounted upon a shaft 23, a gear 25 which is integral with the pinion 24 in mesh with the gear 22 and is mounted upon a shaft 26, and a pinion 21 in 30 engagement with the gear 25 mounted on a shaft 28.

This train of gears serves to retard the rotation of the shaft, due to the operation of the spring I4. The gear I5 is provided with teeth 35 I1 engaged by pawls I8, extending from the periphery of a disc I 9, mounted on the shaft I2 to rotate therewith. Between the disc I9 and the lower surface of the intermediate member 8 is a spring 20, which tends to hold the disc against 40 the gear I5 so that the pawls I8 and teeth I'l will permit the disc and shaft to rotate clockwise for winding the spring I4 independently of the gear, while in anti-clockwise direction the gear and the disc Will rotate together. 45

On top of the plate or support 4 is a drum which comprises a periphery 29 and an end 30 -provided with a hole 3| through which the shaft I2 extends. Mounted on the shaft I2 and above the drum is the sleeve 32 attached to the shaft 50 by means of a screw 33. On the periphery of the drum is a plurality of projections 34 adapted to extend through perforations in a strip of ammunition 35, which is in the form of a roll 36 supported and rotatably mounted on a post 31 suit- 55 o tion strip separated from the drum is indicated by the numeral 4 I.

For the purpose of firing the ammunition a hammer 42 is provided, which is pivoted at one end to a post or pivot 43, while its other end is formed into a hammer head 44 adapted to engage the strip of ammunition between two adjacent projections on the periphery of the drum and a projection 45 adapted to be'engaged by the projections on the drum for the purpose of tripping the hammer, or withdrawing it from the drum.

The hammer is provided with a spring 46 tending to urge the head of the hammer against the drum. This spring is sufliciently strong that when the projection 45 passes over any of the projections 34 the head will be brought into sharp impact with the ammunition strip so that the ammunition will be fired.

For the purpose of holding the train of gears against operation during the time the coil spring.

is wound up, a trigger 41 is provided. This trigger is operated by means of a spring 48 to engage some part of the train of gears to prevent the rotation of any of the parts thereof. The trigge is protected by means of a guard 49.

In order to prepare the pistol for firing the shaft I2 is rotated clockwise by turning the handle I3 so that the coil spring is tightened. During this rotation the drum is stationary and the train of gears is stationary.v The pawls will pass over the teeth I1 but prevent a reverse rotation of the shaft so that the spring is uncoiled. A similar pawl and ratchet mechanism is located in the drum so that the spring may be coiled for operating purposes without rotating the drum, but if the spring be uncoiled the drum is forced to rotate with it and feed and fire the ammunition. On the inside of the drum and attached to the end 30 is a plurality of teeth 50 adapted to be engaged by pawls 5I located on the periphery of a disc 52. This disc 52 rotates with the shaft I2 at all times. Between the disc 52 and the upper surface of the plate 4 is a spring 53. This disc 52 and the pawls thereon are similar in shape to the disc I9 and the pawls I8 thereon. When the l' lshaft I2 rotates anti-clockwise under the action pawls 5I slip over the teeth 50.

The top of the casing is provided with a cover or lid 2a, pivotally attached to the butt end of the casing by means of hinge members 2b. All operating parts are securely housed and protected by the casing and the cover therefor. 'This casing and cover also serve to protect the operator from danger, due to the explosion of the ammunition.

While inoperative the trigger engages the gear and tends to push this gear against the gear 22. 'I'he friction between the gears and between the trigger and one of the gears is suflicient to prevent the rotation of the gears and the parts operated by the spring during the time the trigger is in engagement with the gear 25. 'Ihe trigger is held in engagement with this gear by means of the spring 48. When the trigger is operated against the tension of the spring 48 to release the gears, the spring will cause the drum to rotate and operate the hammer for firing the ammunition.

Thus it will be seen that the pawl I8 and ratchet I1 transmit power from the main spring, mounted on square shaft I2, to the train of gears, which act as a govemer, this train being held stationary by trigger 41, as shown in Figures 2, 5, and 6. The pawl 5I and the ratchet 50 in the feed drum transmit the power from the main spring on the square shaft to the feed drum 38, and at the same time allow the feed drum to idle while the spring is being wound up. Consequently, the feed drum rotates in but one direction only, namely the ring direction, as the main spring unwinds.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
