Specification of Letters Patent.

- Application filed May 14, 1918. Serial N 0. 234,424.

To all whom it may concern:

Be it known that I, PHILIP E. YOUNG, of Fairhaven, Mass, have made certain new and useful Improvements in Toy Aerolanes, of which the following is a specication, reference being had to the accompanying drawings, in which Figure I is an illustration of my toy aeroplane in operation during its ascentand Fig. II is a detailed View showing the aeroplane in descending position.

My invention relates to a toy to be used in connection with a kite, and is designed to travel up the kite string after the kite isin .the air, until it reaches a point in the vicinity of the kite, and then to return to the operator. The toy can very conveniently be made to resemble an aeroplane, and during its return to the operator has a movement very similar to the flight of a real aeroplane.

Referring to the accompanying drawings, 2 is a longitudinal frame member, at the sides of which are positioned a pair of vertical upright members as at 3. Two transverse rods, 1 and 5, pass through the members 3, and are so made that they are free to turn in relation to members 3. Attached to the transverse rods 4 and 5, are wings or airfoils, 6 and 7, which have at their rear edges rods 8 and 9. The wings 6 and 7 are maintained in spaced relationship by the rod 9 pivoted to rods 8 and 9. The union of the longitudinal member 2 and the vertical members 3 may be strengthened by a strut, 10, and if desired, a freely revolving propeller wheel, 11, may be positioned at the front of the longitudinal member 2.

Between the upper ends of the verticalmembers 3 is a pulley wheel, 12, and a guide member, 13. At the rear of the longitudinal member 2 are a pair of uprights l4, carrying a pulley wheel 15, and a guide member 16. A tail fin 17, may be attached to the longitudinal member 2 and the uprights 14. The wings 6 and 7, are normally held in position substantially as shown in Fig. 2 by the operation of a spring 18, which lifts the wings until the rod 9 strikes against the longitudinal member 2. These wings may, however, be depressed into the position shown in dotted lines in Fig. 2, and in order to hold the wings in the depressed position, I supply a catch 19, to which is connected a trigger rod 20. Tension may be maintained on the trigger rod 20, by a spring, 21.

To operate the toy the kite string is moved out on the kite string threaded throughthe guides 13 and 16 underneath the pulley wheels 12 and 15, and a striker plate 22 is attached to the kite string in the vicinity of the kite. After the kite is well up in the air, the wings 6 and-7 are de pressed and the rod 8 is caught in the trigger member '19. The aeroplane is then a little way, when it will be found that the wind will press against the depressed wings and push the aeroplane up the string. When the aeroplane approaches the kite the trigger rod 20 will strike the plate 22, which releases the trigger 19, whereupon the wings 6 and 7 ,will be lifted by the spring 18 into the position shown in full lines in Fig. 2. With the wings in this position, the wind pressure on the device will be so decreased that the toy will return rapidly to the operator. If desired, the toy may be equipped with weighted wheels 23, which are preferably removable, so that if the toy be used in a relatively light wind, it will readily travel up the kite string.

Vhat I claim is:

1. A toy resembling an aeroplane, adapted to move along an inclined string such as a kite string, comprising a pair of spaced wings maintained substantially parallel to each other and each rotatable about a longitudinal axis lying substantially in its plane, said wings being adapted to be rotated into a wind resisting position such that the area exposed to a wind blowing along the supporting string and against the nose of the aeroplane will be substantially the total areaof both wings, a trigger member adapted to hold said wings in such position, means for releasing such trigger and means for rotating the wings into substantially the position of the wings of a true aeroplane when such trigger is released.

2. In a toyresembling an aeroplane, adapted to travel on an inclined string such as a kite string, the combination of a pair of spaced wings maintained substantially parallel to each other and each pivoted on a longitudinal axis lying substantially in its plane, means for holding the wings in a wind resisting position such that the area exposed to a wind blowing along the supporting string and against the nose of the aeroplane will be substantially the total area of both wings, and means for moving the wings, at a predetermined point in the movement of the toy along such string, into substantially the position of the wings of a true aeroplane whereby their Wind resistance is greatly reduced.

3. The combination of a string supported at an incline with the upper end down the wind, a stop on the string, a device resembling an aeroplane adapted to IIIOXB on the string with its tail toward the upper end of the string, comprising a pair of spaced wings maintained substantially parallel to each other and each rotatable about a longitudinal axis lying substantially in its plane, means for holding said wings in a wind resisting position, such that the area of the wings exposed to a wind blowing along the string will be substantially the total area of both wings, whereby the device may be carried up the string by the wind, and means whereby said wings may be rotated into a position substantially similar to the position of the wings of a true aeroplane when the device strikes the stop, to the end that the wind resistance of the Wings may be decreased and that the device may be carried down the string by the action of gravity With the appearance of an aeroplane in flight.

PHILIP E. YOUNG.
