Dec. 2, 1941- s. OPPENHEI M ET AL PROJECTING DEVICE FOR TOY AIRPLANES Filed Feb. 23, 1940 Patented Dec. 2, 1941 KIN-ET ED 4 Claims.

This invention re'latesgenerally'to amusement devices and more particularly to a catapult or projector for launching 'toy airplanes or the like into flight.

The main object of this invention is to provide a new andimproved construction for a toy catapult which will be sturdy and rugged, and emciently adapted for the purposes to which it is directed.

A further object of the invention is to provide, in a device of the character described, a novel means for attaching and maintaining the propulsion means in a highly advantageous manner.

Still a further object of the invention is to provide, in a device of the character described,'utilizing extensible propulsion means, novel means for adjusting the projection tensionoi said-extensible propulsion means.

Still a furtherobject of the present invention assembly and operation, and many ofitsadvantages should be readily understood and appreciated.

A second opening passes through the shuttle perpen- -dijc'ular1y tothedine of -fli'ght (which-obviously isright and left-as viewed-in'Tig. -1) and has the ends thereof countersunk in order to eliminate wear of the propulsion means 25. Said propulsion means consists of a strand or group of strands of fiat rubber, or the like, but may be any elastic extensible device which can be adapted for the purpose herein described. The propulsion band extends from the shuttle 18 to the two openings 26 provided in the arms of a generally Y-shaped member 27 which is fixed to the forward end of the barrel l2 by means of screws 28 or the like. We prefer that the member 21 should be formed from a shock withstanding material, such as a phenol plastic, especially where the body ID of the catapult is of wood. It is to be noted that the member 21 may be firmly attached by reason of the flaired portion I3 providing ample room for strong screws or other fastening means. In our illustrated embodiment, the head 59 of the rod member I! aids in maintaining the member 2? in place.

The propuision band 25 passes through the openings 26, between the arms of the Y-shaped member 21, and passes to the opening 24 in the shuttle. Where the member 25 has been formed by joining the free ends of strand or strands, the

joining knot or splice is best positioned within the opening 24. If it is desired to increase the propulsion tension of the band 25, the front portion thereof which extends between openings 26 may be stretched downward to engage the notch H4 on the underside of the flared portion l3 as shown by broken lines of Fig. 1. While only one notch is disclosed, it is obvious that a plurality of such notches will increase the tension adjustability of the member 25.

The shuttle member I8 is pulled rearward, when it is desired to operate the catapult, by grasping the portion 29 provided therefor on the upper side of the shuttle and moving same to the right as viewed in Fig. 1. This motion tensions the band 25 so that if released the shuttle will snap to the left. The grip H is provided with a trigger member 39 pivoted at 3|, having a hook portion 32 with a rounded forward face 33 and a sharp-cornered rearward face 34. The hook portion 32 projects through a passage 35 provided therefor in the barrel l2, and is disposed in the groove 2: in the path of the shuttle IS. The spring 36 provided in the grip cavity 31 engages the trigger member 30 at the projection 38 and normally tends to force the trigger member 30 in a clockwise direction about the pivot pin 3|, thus keeping the upper end of the hook portion 32 in the position shown in Fig. 1.

When the shuttle I8 is moved to the right, the

corner 39 of the tongue 22 engages the rounded portion 33 of the hook 32 thereby depressing the trigger member 30 against the tension of the spring 36 while the shuttle is moved past the hook portion 32. However, as soon as the shuttle passes the opening 35, the hook springs back into position so that the corn-er 34 engages and holds the front corner of the shuttle preventing the tension of the member from pulling same forward.

When it is desired to release the shuttle l8, pressure on the finger portion 40 of the trigger member will move the portion out of the path of the shuttle, causing same to fly forward for obvious reasons.

In order to prolong the life of our catapult and minimize the shock caused by the shuttle striking the portion 15 after traveling its path, we provide shock absorbing means, comprising a coiled spring member 4l disposed on the forward end of the rod member I1. Washers are associated therewith in any convenient arrangement. Besides the shock absorbing advantages of the member 4|, the elimination of shock from the shuttle at the end of its stroke will prevent breakage and misadjustment of the airplane 42 or other device carried by the shuttle l8.

The airplane which is adapted to be used in connection with our catapult is a simple one, comprising a single fuselage member 43, weight at its front end 44, and having a horizontally disposed wing 45, horizontal tail member 46 and vertical rudder 41. For the accommodation of the plane 42 in an eflicient manner which will eliminate the need for any special appliances being attached either to the plane or the shuttle l8, we provide the shuttle with a group of forwardly extending fingers adapted to firmly engage the tail assembly of the airplane 42. Said fingers are four (4) in number in order to accommodate an airplane of the form illustrated, but obviously the number may be increased or decreased in accordance with the construction of the airplane which it is desired to launch.

The fingers 48, 49, 50 and 5| are separated vertically in order to accommodate the tail member 46. They are also separated horizontally slightly more than vertically in order to accommodate the fuselage member and permit the vertical rudder 41 to protrude between fingers 48 and 49.

It will thus be seen that the airplane 42 is adapted to be firmly held in the shuttle and yet be free to be launched forward when the catapult is operated. The broken lines of Fig. 1 show the shuttle with the airplane 42 associated therewith poised prior to release of the shuttle by trigger in a manner described. The solid lines show the shuttle and airplane at the extreme left end of the path of the shuttle before the same had been drawn back to the position shown in broken lines. It is obvious how the device operates and hence further explanation will be dispensed with.

It is believed that our invention, its mode of construction and assembly and many of its advantages should be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the perview of our invention as defined in the appended claims.

What we claim and desire to secure by Letters Patent of the United States is:

l. A device of the character described comprising an elongated substantially L-shaped member arranged so that one leg thereof forms a grip and the other leg forms the barrel portion of a catapult, an elongated recess provided in the top edge of the barrel portion and being blocked ofi at either end thereof, and defining thereby a track within which a shuttle is adapted to be disposed, an elongated rod member disposed within said recess and extending between the ends thereof, a perforated shuttle slidably mounted on said rod through the perforation thereof and adapted to slide in said track, an extensible member attached to the forward end of said barrel portion and also being attached to said shuttle whereby when said shuttle is moved to one end of said track adjacent said grip portion of said L-shaped member said extensible member will tend to pull said shuttle forward in said track, and trigger means releasably holding said shuttle in said last mentioned position and against the tension of said extensible member, said rod member having a shock absorbing spring associated therewith at the forward end thereof for I cushioning the shuttle as it reaches the forward end of the recess in its forward motion.
