Patented Nov. 15, 1938 UNITED STATES PATENT OFFICE TOY VEHICLE Application April 2, 1937, Serial No.,134,643

In Germany January 1! '1 3'1 3 Claims.

This invention relates to toy-vehicles which preferably may be of the type of an automobile, a caterpillar tank or the like and consists essentially therein that the toy-vehicle is provided with a detonation-device that is periodically operated together with said toy-vehicle by means of a spring-driven clockwork.

A toy-vehicle operated by a spring-driven clockwork and provided'with such a detonation-device will thus, in addition to 'its travelling motion, periodically operate said detonation-device. The latter, moreover, may form a natural supplementation of the toy, especially in case this is constructed in the form of a war-vehicle, such as a caterpillar-tank, an armored caro'r the like.

In the accompanying drawing which forms part of this specification I have shown an example of a construction of my present toy-vehicle, Fig. 1 being a longitudinal section through a toyvehicle constructed in the form of a tank-vehicle with a caterpillar drive and Fig. 2 a plan-view on Fig. 1 with the cover or casing of the vehicle removed.

Referring more particularly to the drawing,

-' the under part I of the casing of the vehicle comprises the spring-driven clockwork 2 which serves to drive the wheels of said vehicle to produce the travelling motion of the latter. On the winding-stem 3 of said clockwork is fixedly mounted a toothed cam 4, which upon rotation of the latter will come periodically into engagement with a nose l3 provided laterally of the hammer 6 which is mounted above said toothed cam 4 to swing about an axle or pivot 5 fast on one of the lateral plates of said clockwork. n the axle ,5 of saidhammer there is further mounted a pair of actuating wheels I freely rotatable about said axle. A resilient pawl 8 is further provided on said hammer to periodically rotate said wheels I as soon as the former is being raised by action of the teeth on said cam 4. Underneath the head of said hammer 6 there is fixedly mounted an anvil l0. 'A U-shaped guide-rail or channel 9 is pivotally connected at one'end thereof to said anvil l0. Said guide-rail or channel 9 is provided at the rear part thereof with an upwardly bent handle and near its front end on which it is pivoted to said anvil with an arm ll bent down-,- ward near the front end of said guide-rail or channel 9. To the end of said arm I i is connected one end of a spring l2, the other end of said spring being connected to said hammer 6. Said guide-rail or channel 9 will thus be resiliently pressed by action of said spring I! against said pair of wheels 1 and the hammer 6 drawn to swing towards said anvil iii. A strip ll hav ing a series of primers thereon is being drawn oil a reel II and periodically fed alongside said guide-rail or channel 9 in direction towards said anvil ill by action of the wheels I which themselves are periodically rotated by said hammer by the intermediary of said resilient pawl 8. The primers on said strip I 4' will thus be sup plied in succession to said anvil to explode and produce a detonation, whenever said hammeris hitting against said anvil and a. primer therebetween. The detonation device, as a whole, is periodically actuated by the teeth of said cam Q on said winding-stem 3, the several teeth of said cam upon rotation of the latter by said clockwork coming periodically into engagement with said nose ii on the arm of said hammer, with the result that the latter will periodically swing .upward about its axle 5 against the action of spring ii. The wheels I by way of said pawl 8 will thus likewise be periodically rotated and impart periodical feeding motion to said strip either in uniform succession or with proper intermissions therebetween.

The casing of the toy is preferably provided with an upper part which may be folded onto the under part of the casing so that the clockwork together with the detonation-device may be exposed to permitinspection thereof and also insertion of a reel ll of strip and primer material.

I claim: p

1. A toy-vehicle comprising a spring-driven clockwork to impart travelling motion to said vehicle, a detonation-device, mechanism forperiodically actuating said detonation -device by said clockwork, said detonation device comprising a hammer, an anvil and a pivoted guide rail for the reception of a strip having primers thereon, a pair of feeding wheels adapted to periodically feed said strip along said guide rail to said anvil, and a spring tending to press said guide rail against said feeding wheels with said strip interposed therebetween.

,2. A toy-vehicle comprising a spring-driven clock-work to impart travelling motion to said riodically actuating the detonation-device by said clock-work, the said mechanism comprising an anvil, a hammer cooperating therewith, a spring tending to cause" the hammer to hitthe anvil,

means operated by the mechanis mior periodically tensioning said hammer against the, action of said spring and for periodically releasing said hammer to hit against said anvil, and feeding means controlled by said hammer for 'iieriodically feeding a strip having primers thereon to said anvil to cause explosion of a primer, when positioned on said anvil, by the actionof said hammer when released by said means.

3. A toy-vehicle comprising spring-driven clockwork to #iinpai't travelling motion to said vehicle, a 'de'tonating device, mechanism for -'peinterposed therebetween, the said spring being connected to the hammer and tending also to force the hammer against said anvil, a toothed cam mounted on an axle of said clockwork for periodically tensioning the hammer against the action of the spring and releasing the hammer to hit against a primer on the anvil.
