` TOY PRoJEGTILE-LAUNCHING VEHICLE Filed'MaICh 15, 1940 INVENTOR Kamer/Z F95 ATTORNEYJ Patented July 14, 1942 y UNITED STATES PATENT OFFICE TOY PROJECTILE-LAUNCHING VEHICLE Robert R. Fast, Milwaukee, Wis. Application March 15, 1940, Serial No. 324,073
This invention relates to improvements in toy projectile-launching vehicles.
It is the primary object of the invention to provide a toy vehicle, preferably self-propelled, with means for automatically launching or catapulting a series of projectiles or the like. In the preferred embodiment herein disclosed by Way of exemplifying `the invention, the vehicle is an airplane carrier and the projectiles are miniature airplanes which are launched or catapulted into the air successively during the operation of the carrier vehicle.
It is a further object and important object of the invention to provide means whereby such a device as that above indicated 'may be made at modest cost and with the greatest simplicity whereby it will withstand hard `usage without damage.
Other objects will be apparent to'those skilled in the art upon scrutiny of the following disclosure of the invention.
In the drawing:
Fig. 1 is a View in perspective showing my improved toy in use.
Fig. 2 is an enlarged plan view of the toy exemplifying the invention.
Fig. 3 is a plan View of the toy `with the deck and super structure removed.
Fig. 4 is a fragmentary plan view of a modified embodiment of the invention.
Fig. 5 is a fragmentary detail view in perspective diagrammatically illustrating the catapulting mechanism.
Like parts are identified by the same reference characters throughout the several Views.
While my invention is applicable to a variety of vehicles, such as automobiles, tanks, bombing planes, Iairplane carriers and submarines and to a variety of projectiles, such as machine gun bullets, tank gun shells, bombs, airplanes and torpedoes, I have chosen an airplane carrier and its airplanes to exemplify the invention, this being one of the most attractive embodiments. The particular airplane `carrier herein illustrated is `a boat actually adapted to be operated in the water. It will, of course, be understood, however, that, as is frequently done with such toys, the boat may be made up for use on a dry surface and may either be provided with wheels or endless treads for self-propulsion or may merely have a flat kbottom to be pulled across the floor.
In the preferred form of my invention, the boat hull 6 is made to oat in the water. It is provided with a deck l on which there is a moving slide 8 or a rotary turntable 80 which, in
either case, serves as a carrier to feed successive projectiles to the catapulting or projecting device.
The slide 8 has a series of slots 9 in its surface through which the catapult spring I Il finds access to lugs II on the under surfaces of the projectiles I2 which, for the purposes of the present disclosure, comprise miniature airplanes. The lugs I I are preferably ballasted so that the catapult spring III `strikes the projectile close to its center of mass to increase the realistic eifect of Hight.
The slidable deck section or carrier .8 shown in Fig. l and Fig. 2 is guided for reciprocation longitudinally of hull A6 by means of overhanging flanges I5. The slide has teeth at I6 comprising narrow strips of metal intervening between the punched apertures I'I which receive the teeth of a propelling gear I8 mounted on the shaft I9 of the winding key 20 for the spring motor 2| This motor is connected through its gear train with a driven shaft 22 provided with a crown gear 23 in mesh with pinion 24 to turn the propeller shaft .25 Yand the propeller 2,6 which, for the purposes of this disclosure, exemplifies any means for the self -propulsion of the vehicle.
As the spring motor turns the propeller, the key shaft turns in an unwinding direction and the gear I8 transmits motion from the key shaft to the slide 8 to cause the slide to move forwardly upon the deck of the toy vessel. This brings each successive projectile or miniature plane I2 into registry with the catapult spring I0.
As the key shaft I9 turns in an unwinding direction (counter clockwise, as viewed in Fig. 5), its crank 28 moves over the notched portion 29 of the catapult spring I0 and engages the Spring at a point below the notch to flex it rearwardly and thereby to store up energy in the spring. At a predetermined point in the rotation of the crank 28, the crank 28 will again move through the notch at 29, thus suddenly releasing the spring and the release if the spring is so timed to the advance of the slide that when the spring is released the advancing slide will present in the path of the spring the lug I I of the next projectile I2, whereby the spring, engaging the lug II of said projectile, will catapult it upwardly and forwardly into space as indicated in Fig. 1.
The arrangement shown in Fig. 4 is identical in principle of operation except that in this device the carrier 80 is a disk pivoted to the deck at |51) and rotated to bring successive projectiles into registry with the catapult.
It will be obvious that any type of projectile might be simulated and an appropriate type of vehicle for that projectile might be provided with means along the lines of that herein disclosed for launching or catapulting the appropriate projectile in the course of vehicle advance. The particular driving connections and the particular catapulting spring herein disclosed represents the simplest and least expensive construction I have devised for the purpose, but I do not regard the invention as being limited to these specific structures.
