* nrrsn STATES CLAIRE S. JONES, OF WYANDOTTE, MICHIGAN.

TOY AEROPLANE;

Application filed July 31, 1925.

To all whom it may concern Be it known that I, CLAIRE S. Jones, a citizen of the United States, residing at \Vya-ndotte, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Toy Aeroplanes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to toy aeroplanes and has for its object to provide a construction which may be very easily and cheaply manufactured from sheet metal or similar material and assembled in a very simple mannner, and which at the same time will be of a durable nature capable of withstanding considerable use and having excellent gliding qualities.

Further objects subsidiary to or resulting from the aforesaid objects, or from the construction or operation of the invention, as it may be carried into effect, will become apparent as the said invention is hereinafter further disclosed.

In carrying said invention into effect, I may provide a body of light sheet metal or other similar material of a rigid nature capable of being formed to shape, said body being in the form of a long narrow channel or trough with the sides thereof brought to a point at the front end and the rear end extended laterally of the body in the form of tail fins, a pair of propellers mounted at the outer ends of said tail fins, propeller operating rubbers extending from the propeller shafts to suitable attaching means at the forward end of the body, and an airfoil transversely mounted on said body intermediate of its length.

All of which is more particularly described and ascertained hereinafter, by way -of example, having reference to the accompanying drawing, wherein- Figure 1 is a perspective view of a toy aeroplane constructed in accordance with the invention; 1

Figure 2 is a plan of the same;

Figure 3 is a transverse section of the body taken on the line 3 3 Figure 2 and illustrating the transverse air-foil; and c Figure 1 is a transverse section of the body taken on the line P- P, Figure 2.

Similar characters of reference indicate similar parts in the several figures of the drawing.

The body of the aeroplane is shown as Serial N0. 47,212.

and 9 of the said fins are approximately in the same plane as the edges of the walls 2 and 3 of the body, the rear trailing edges 10 and 11 of the said fins being inclined from the said plane to the said point 0 at the base of the V-shaped trough. This gives an inclination of the said fins upwardly in forward and lateral directions, assisting in the stabilizing of the rear end of the aeroplane.

The airfoil 12 extends transversely of the body and is downwardly inclined to its center (Z, the said airfoil being secured in position in any suitable manner, such as that shown, wherein the said airfoil is attached by a flexible band 13 which may be of rubher and which passes over the plane 12, the ends being looped beneath the body 1. This admits of the airfoil being adjusted as to position along the length of the body as may be required to attain the proper balancing of the aeroplane when in flight, and also admits of the said airfoil 12 being detach-ed to facilitate packing or shipping. The body and the airfoil I prefer to make of light sheet metal such as aluminum.

The fins 8 and 9 are provided near their i extremities with downwardly depending lugs 14 and 15 perforated at 16 and 17 to form journals for the shafts 18 and 19 of propellers 20 and 21, and 22 and 23 are rubbers providing the motive power for the said propellers and extending from the said shafts 18 and 19 to hooks 2 1 and 25 by which their forward ends are attached to the looped wire 5.

A toy aeroplane constructed in this mannor can be flown very readily and for some distance, having excellent gliding qualities, and its simplicity renders it capable of ready production as a low cost.

This invention may be developed within the scope of the following claims without departing from the essential features of the lit) said invention, and it is desired tiat the specification and drawing be read as merely illustrative and not in a limiting sense, ex cept as necessitated by the prior art.

l 7 hat I claim is z- 1. A toy aeroplane comprising an elongated trough shaped body provided with integral laterally extending fins at its rear end, propellers mounted atthe extremities of said fins, a transverse airfoil secured intermediate of the lengtn of said elongated body, and means for effecting the rotation of said propellers.

2. A device according to claim 1, wherein 15 the propeller rotating means are in the form of rubber bands extending rearwardly and outwardly of the body from the forward end thereoi towards the extremities of said fins.

3. In a toy aeroplane, an elongated body, tail fins extending laterally from the rear end of said body, lugs on the extremities of said tail fins, propeller shafts jonrnaled in said lugs, and motors comprising rubber bands ext-ending and diverging from the forward end of said body to said propeller shafts.

In testimony whereof I a'iiix my signature.

CLAIRE S. JONES.
