MULTIPLE ACTION TOY GUN Filed NOV. 28, 1952 Patented July 27, ,1954

UNITED STATES RTENT OFFICE 4 Claims.

This invention relates to new and useful irnprovements in toy guns and it is among the objects thereof to provide a toy gun which by a single trigger action causes repeated reciprocatory movement of the barrel element complemented by sound.

It is a further object of this invention to provide a toy gun of the above designated character of a construction in which a trigger slide and reciprocating barrel are coordinated by a floating gear wheel and which is provided with means for preventing misalignment of the wheel to prevent interference with the free movement of the parts.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Fig, 1 is a side elevational view of a gun embodying the principles of this invention,

Fig. 2 a similar view with the side wall removed to illustrate the moving parts, and

Fig. 3 a vertical cross sectional view taken along the line 3 3, Fig. 2.

With reference to the several figures of the drawing, the numeral l designates the gun stock, 2 the handle or grip, 3 a reciprocating barrel and 4 a trigger slide on which is mounted a trigger 5 of elongated rectangular shape. As shown in Fig. 2, the slide 4 is recessed at 6 and abuts a wall portion 1 of the stock I, which is a stop. The trigger slide 4 is provided with a gear rack 8, Fig. 2, and a rearwardly extending portion 9 that abuts the coil spring I disposed in a recess I l of the stock I. The trigger slide 4 is provided with grooves I2 that interact with lugs in the gun stock to act as a guide to prevent binding of the slide when subjected to trigger action. The gun barrel 3 is similarly provided with grooves I3 and i4 to maintain alignment of the barrel and particularly a gear tooth I that extends downwardly and is engaged by a pinion I6, the teeth of which also interact with the teeth of the gear rack portion 3 of the trigger slide. A feature of the invention is the mounting of the pinion I6 by providing extending trunnion portions Il that are free to slide in slots I8 of the side walls of the gun stock I. A light leaf spring I9 is inserted ina notch of the barrel 3 and extends downwardly to constitute a spring abutment for the pinion I6. The gun stock I is provided with projections or anvils 2| and 22 that bear on a leaf spring 23 mounted in a notch 24 of the stock I.

A wing portion 25 extends upward through a slot in the top of the stock and is integrally joined with the barrel 3, the wing having a constricted portion that moves between shoulders 26 and 2l of the gun stock I. A coil spring 28 disposed in a recessed portion of stock I normally biases the barrel 3 towards the rear of the stock and a plurality of disc-like members 29 are loosely mounted on the barrel for sliding movement in an axial direction. Ornamental openings 30 are provided in the forward end of the stock I, as is also an ornamental perforation 3I in the body of the stock. As shown at 32, Fig. 2, solid portions of the stock may be recessed to reduce weight.

The operation of the above described toy gun is briefly as follows. With the trigger 5 released, it is fully extended by action of the coil spring I0 against the trigger slide 4 with recess 6 abutting shoulder 1 in the manner shown in Fig. 2, this being the idle position of the gun. In this position the pinion I6 interacts with tooth I5 and the teeth 6 of the trigger slide, respectively, and spring I9 has acted to move the pinion I6 bodily in the slots I8 to the position shown in Figs. 1 and 2. When the trigger slide i is actuated by retracting or pulling the trigger 5, it will cause pinion I6 to revolve by Virtue of its tooth engagement with the trigger slide gear tooth rack and the pinion in turn will cause barrel 3 to move forward within the distance of the pitch of the teeth. Forward movement of the barrel 3 is against the action of coil spring 28 so that when the tooth I5 of the barrel slips oil", the spring 28 will cause barrel 3 to retract until tooth I5 again engages one of the teeth of the pinion I6.

When the pinion I6 is revolved by action of the trigger slide gear rack the leaf spring 23 will be raised against its iulcrum point 22 by the pinion teeth and upon continuing rotation of pinion f6, the end of the spring will slip oi the pinion tooth and strike the lug or anvil 2l, producing sound.

By a single retraction stroke of the trigger, the barrel 3 will reciprocate as many times as the teeth 8 of the trigger slide rack advance the teeth of the pinion I6, and the leaf spring 23 will slap down on the anvil 2| a corresponding number of times. The pinion I6 is a iloating member that coordinates movement of barrel 3 and slide 4 by its teeth interacting with teeth 8 of the slide 4 and tooth I5 of barrel 3. As each tooth of pinion I6 advances counterclockwise in response to movement of slide 4, it will displace tooth I5 forward until it slips off the pinion tooth and returns by action of spring 28, The spring I9 functions to prevent forward movement of pinion I6 to the end of its slots i3 that would cause the top of the teeth of pinion IE to engage the bottom of the tooth l and wedge or bind. When the barrel is reciprocated, the discs 29 will be subjected to reciprocating movement on the barrel in addition to the movement of the barrel to produce an animated effect. When the trigger 5 is released by removing the finger therefrom, coil spring iii will automatically return the trigger slide to the forward or idle position shown in Fig. 2 of the drawing.

It is evident from the foregoing description of this invention that toy guns made in accordance therewith produce a novel reciprocatory barrel movement with complementary staccato sound effects pleasing to children.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction such as in the choice of materials for strength, weight, sound and appearance, without departing from the principles herein set forth.
