New York I Application September 13, 1941, Serial No. 410,694 g 22 Claims.

This invention relates to toys, and more particularly to a toy tank which shoots projectiles as it runs.

Primary objects of my invention are to generally improve my guns and toy tanks. A more particular object is to provide a relatively powerful toy tank capable of climbing over obstacles in a realistic manner, and which at the same time forcefully ejects projectiles of substantial size through a simulated cannon.

Further specific objects of theinvention are to provide a relatively sturdy simplified ejector mechanism for the gun; to prevent interference between the ejector mechanism and the shaft operating the same; to provide adequate torque for operating the gun by using the main stem of the motor as the operating shaft; and to avoid operation of the gun as well as operation of the tank wheels when winding the spring motor.

Still further objects of the invention center about a the projectile magazine, and are to avoid an unsightly chimney-like projection on the tank or over the gun, and at the same time to simplify the structure and minimize the cost of the magazine, as well as to make the same readily removable when not in use, for more compact packaging of the tank.

To the accomplishment of the foregoing objects and such other objects as will hereinafter appear, my invention consists in the toy gunand tank elements and their relation one to the other as hereinafter are more particularly described in the specification and sought to be defined in the claims. 'The specification is accompanied by drawings, in which:

Fig. 9 shows the projectile used with the gun; Fig. 10 schematically illustrates a modified ejector spring mechanism;.and 1 Figwl'l' is a side elevation ofthe same. Referringto the drawings and more particul and 2, the complete toy comprises a tank body B which moves on caterpillar treads T. The tank includes a simulated gun G which is supplied with projectiles from a magazine M. Both the gun single spring motor housed within Considering the arrangement in greater detail, and referring now to Figs. 3-6, the projectile is fired by means of; an ejector spring generally The-upper end l2 of spring S is movablethrough the breech portion of the gun, and the latter is provided with an open slot 14 at the bottom for this Purpose. The spring is actuated by a spring-tens'ioning on a shaft l8 exte ding transversely across the tank. The lower end :20 of spring S is fixedly mounted at a point below the gun and substantiallybelow the shaft Hi. In the present case the wheel It; is a crank disc carryingv a 'crank pin 22. The crank pin rotates clockwise as viewed in Figs. 3, 4, and 5 of the drawings.

Referring to Fig. 4, the crank pin bears against the spring in the position. 22 and so bends the spring rearwardly'frorn the broken line position l2 to the solid line position i2. At this time the lowermost projectile 24' is raised or tilted slightly to accommodate the rearward movement of the spring. As the rotation of the crank proceeds, the crank pin 22 moves the spring to the solid line position shown in Fig. 5, at which time the crank pin reaches a sharp bend 2 6 in the spring. When the crank pin moves slightly-further to the broken line position 22 shownin Fig. 5, it clears the upwardlybent part 28 of th spring, thus permitting the latter to fiy forward to the broken line positions, During this forward movement, the upper end L2 strikes the rear end of projectile 29 and ejects 'it forcibly through the gun barrel. The [continued forward movement of the spring is arrested whenthe upright portion 30 thereof reaches the crank pin in its position 22. A sharp blow or percussive noise is produced at this time, which accompanies the ejection of the projectile and heightens the realism of the toy. During the continued rotation of the crank disc, the spring remains substantially in its forward will be oserved that the shapeof the spring S is such that the shaft l8 does not interferewith the movement of the spring.

The tank (is driven by. a spring motor having a main windingystem I8. This extends all the way through the tank from one side to the other and may be bent at one end to form an integral winding key 10 (Fig. 2

governor described box formed by side The step-up gearing and? carried in a gear other is associated with the wheel IS. The latter is shown in Figs. 3 and 6, and comprises a toothed ratchet wheel II8 mounted on main stem I8 and cooperatingwith a dog I20 pivotally mounted at M2 on wheel I6 and acted on by a spring wire I24 carried on wheel I6. During winding of the spring motor the crank pin 22 reaches a position of rest in the acutely bent part of the spring S, as is shown in Fig. 3, thus preventing rotation of the crank disc. The other ratchet mechanism is shown in Fig. 6 and comprises a ratchet wheel I26 identical with the ratchet wheel H8 and cooperating with a similar dog, the said dog being carried on the face of main gear 18 in the same manner that the dog I20 is carried on the face of crank I6. It will be evident that with this arrangement the spring motor may be wound without rotating either the main gear 18 or the crank disc I6.

A modified form of ejector mechanism for the gun is shown in Figs. and 11. In this arrangement the spring is a flat steel spring I30 having its lower end I32 fixed in'position beneath the gun and beneath the shaft I8, much as was previously described. The upper end is narrowed to form a thin head I34 adapted to move in the slot at the breech of the gun. The spring is slotted or cut away at I36. The spring is operated on by a wheel I38 carried on shaft I8, but

in this case the wheel I38 is a cam rather than a crank. Rotation of the cam bends the spring I30 rearwardly until the point I46 of the cam reaches the upper end of the slot I36 whereupon the spring flies forwardly. A noise simulating the firing of the gun is produced when the spring hits the small radius part I42 of the cam.

The cam I38 is preferably provided with ratchet mechanism similar to that previously described and including a ratchet wheel cooperating with a dog I20 acted on by a spring I24. It will be evident that with this arrangement the operation will be as previously described, and further that the shaft I8 will not interfere with the desired range of movement of the ejection spring.

It is believed that the constructionand operation, as well as the advantages of my improved toy gun and tank will be apparent from the fore going detailed description. The magazine is readily loaded with projectiles, and these cannot change from the desired parallel relation. The tank is wound while the motor is held against unwinding by the starting lever. As the tank is wound there is no movement of the caterpillar tread nor of the gun mechanism. When the starting lever is released the tank is propelled forwardly with a powerful drive enabling it to surmount steep obstacles. As it proceeds the projectiles are fired forcibly from the gun at well spaced intervals. Each discharge is accompanied by a percussive noise simulating the firing of a cannon. The ejector mechanism is simple and rugged in character and provides a forcible ejection of the projectile. Adequate torque for the same is provided by using the slow speed main stem of the motor. The magazine is simple and inexpensive in construction, effective in appearance, and is readily removed for compact packaging of the tank during shipment and sale.

It will be apparent that while I have shown and described my invention in preferred forms, many changes and modifications may be made in the structures disclosed, without departing from the spirit of the invention as sought to be defined in the following claims.
