TO) AIRPLANE Filed Oct. 28, 1929 2 Sheets-Sheet 2 31wentor Patented Oct. 14, 1930 UNITED STATES PATENT oFFicE WILLIAM '1. WELCH, OLE NEW ORLEANS, LOUISIANA TOY AIRPLANE 1 The present invention relates to improvements in toy airplanes and has for an object to provide an improved toy airplane of that type which is adapted to travel back and forward on a string, one end of which is secured to the wall or a fixed support and the other end held in the hand of the operator.

Another object of the invention is to provide an improved toy airplane so constructed as to assume a position of delicate balance and stability on the string with means to avoid the bobbing up and down ofthe airplane which action would interfere with the speed of the same.

A further object of the invention resides in providing an improved toy airplane in which an improved wing structure is had providing therefrom the supports for the landing wheels, suspension pulley and string guide.

A still further object of the invention is to provide an improved airplane in which a modification of the rudder construction is involved to form a stabilizing eye for engaging the supporting string.

With the foregoing and other objects in view, the invention will be more fully described hereinafter and will be more particularly pointed out in the claims appended 80 hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views Figure l is a perspective view of an improved toy airplane constructed in accordance with the present invention.

Figure 2 is a top plan view of the same.

Figure 3 is a side elevation.

Figure 4 is a front View.

Figure 5 is a side view with parts broken away and parts shown in section, and

Figure 6 is a transverse sectional view of the improved airplane. v

Referring more particularly to the drawings, 10 designates a body or core in the nature of a fuselage. This body may be of any suitable material and has at its forward nose 11 a rotary propeller 12.

The rear portion of the body 10 carries the rudder mechanism 13 which is preferably made from sheet metal. An eye 14 is also preferably stamped from the sheet metal of the rudder mechanism and twisted at substantially right angles as designated at 15 whereby the axis of the eye will lie parallel with the axis of the body of the airplane to receive freely therethrongh the supporting string 16, one end of which may be aiiixed to a wall or some other stationary support, while the opposite free end is held in the hand of the operator.

This string 16 also passes beneath a grooved pulley 17 located at the center of balance of the airplane'and journaled on a shaft 18 mounted in upstanding bearing arms 19 that are preferably stamped from the upper metal plane or wing 20. Cut out portions 21 are shown to be the result of the stamping out of the upstanding supporting arms 19, these arms being bent upwardly from the plane of the wing 20. A string guide 22 is also stamped out from the material of the wing 20 as shown by the out out portions 2-3 which overlies the body 10, so that the body reinforces and strengthens the wing structure at a point where this cut out portion 23 occurs.

The string guide 22 is formed with an elongated slot 24 for receiving therethrough the string 16. The guide 22 is areferably curred to conform somewhat to the curvature of the grooved periphery of the pulieyl'? but is spaced from said pulley and acts to prevent the string from leaving the groove of the pulley and from getting between the sides of the pulley and the supportin arms 19 where such string would jam and become dificult of disentanglement. I

The lower plane is shown. at 25 and is pref erably formed in one piece with the upper plane 20, being connected therewith by a central web 26 which is formed with an opening 2'? to receive the body 10 of the airplane. there being ample portions of the web 26 surrounding the body 10 to reinforce and strengthen both wings. Also there are pref erably struts or braces 28 between the upper and lower wings 20 and. 25 outwardly of the web 26 to serves to maintain the proper reia-' tionship and distance between the two pianes.
