TOY FLYING-MACHINE.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed February 19, 1910. Serial No, 544,761.

To all whom it may concern: 4

Be it known that we, ISAAC W. HUM- PHREY andHA'nRY A. SPURGEON, citizens of the United States, residing at Da ton, in the county of Montgomeryand' tate of Ohio, have invented certain new and useful Improvements in Toy F lying-Machines; and we do declare the following to be a full, clear, and exact descri tion of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to new and useful improvements in toy aeroplanes.

The object of the invention is to provide a toy of the above description which may be constructed at a minimum cost and which possessesthe novel and advantageous features hereinafter described 1n the specification and pointed out in the claim.

In the accompanying drawings, Figure 1 1s a erspective view of our improved toy aerop ane. Fig. 2 is-a side elevation of the same. Fig. 3 is a top plan view of the motor frame.

In the specificatlon and drawings, similar reference characters lndlcate corresponding parts.

1-1 designates upper and lower supporting planes which are held apart by means of two endbraces 22 and intermediate side marginal braces 3-3. The planes 1-1 are constructed of thin tenacious paper or any other suitable material which is held taut or in sha e b a light framework 4 preferably ma e o ratan. The braces 3-3 are attached directly to the frame-work 4, and the intermediate portions of the frame are reinforced as at 5 to strengthen them at such late braces 3--3 is a propeller shaft block 6 from which rearwardly extend members 7 which constitute the frame work of the points.- Mounted on the forward intermemotor; The members 7 are attached to the rear braces 3 -3 and the said members at their rear ends support the rear planes 8'-8 which are of areas approximately one fourth the area of the front planes 1- 1. The rear planes 88 are constructed in a manner similar to the front lanes 1'1 and the same consist of ratan rames 9 and upright braces 10 and 11. The rear intermediate braces 11 pass tightly through the extreme motor frame while the forward intermediate braccs'll ass somewhat loosely through the motor rame members 7. At the junction of the motor frame members 7 and the rear intermediate braces 11, is mounted a blockt12 which supports a in 13. Passing around the pin 13 is an en ess rubber band 14 which is attached at its opposite end to a 100 or eye 15 on the innerend of the prope ler shaft 16 which is journaled in the block 6. This elastic band 14 constitutes the motor which drives the pro eller 17, the latter being mounted upon tile end of the shaft 16. When it is desired to fly the machine, the propeller 17 is rotated by the fingers in a direction opposite to that which propels the machine forward, and until sulficient energy is stored in the motor or elas tic band 14 to drive the propeller. The machine is then released or thrown into the air and is caused to soar or fly under the influence of the revolving pro eller. From Fig. 2 it will be noted that the ongitudinal members 7 constituting the motor frame, curve downwardly and to some extent offer the least resistance thereby to the upward movement of the toy. The rear planes 8-8 may be shifted to vary their angles up or down relatively to the planes of the forward sustaining members 1-1, This may be'done by pressing upwardly or downwardly the front portions of the rear planes 8 8, it having been stated that the forward intermediate braces 11 of said planes are sufiiciently loose where they pass through the frame members 7, to permit of such changing of the angle of said planes. The prope ler blades 17 are comppratlvely light bemg constructed prcfera l of aluminum, and the device as a who e 1s exceedingly light owin to the material from which it is constructe a We claim:

-A toy of the type speclfiecl comprising a downwardly curved motor frame extending the len th of the device and constituting the main rame, a pro eller supported on the forward end of sa-i frame, an elastic motor having one end connected to the shaft of said propeller and the other end connected to the tailiece of the motor frame, two forwardly isposed planes held apart by end braces and supported on the motor frame by intermediate braces, and two rearward planes having areas approximately one intermediate fourth of the areas of the front planes, said rearward planes being held apart by end braces and sup orted on the motor frame by races engaging the motor frame and the tail-piece of the motor frame, said rear planes belng' adapted to be varied in their angles relative to the front planes,

as herein shown anddescribed.

In testimony whereof we afi'ix our signatures, 1n presence of two Witnesses.
