Description

TOY HELICOPTER Filed Jan. 6, 1944 Patented Aug. 14, 1945 to John Brayley, Minneapolis,

trustee Minn, as

Application January 6, 1944, Serial No. 517,206 '1 Claim. (01. re-75) This invention relates to aerial toys and more particularly to a toy having a rotating propeller which will cause the toy to rise into the air.

It is a general object of the invention to provide an aerial toy including a frame or body rotatably supporting a lifting propeller and means in combination with the body for opposing the tendency of the body to rotate as the device travels in the air.

Another object of the invention is to provide an aerial toy including a frame generally simulating the fuselage of an airplane, a rotatable propeller on the frame and a stabilizer similar to the tail of an airplane to oppose the tendency of the frame or fuselage to rotate.

Still another object of the invention is to provide an aerial toy generally simulating a heli-. copter which can be actuated by hand and which, due to its light structure, is capable of comparatively extensive flights.

These and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawing, wherein like reference characters refer-to the same parts throughout the views, and, in which:

' Fig. 1 is a plan view of the device: and V Fig. 2 isa side elevation thereof.

The main frame A is made up of a pair of side members 3 which merge into a streamlined nose Ia and which converge toward their rear or right hand ends as viewed inthe drawing. The rear ends of the side members! have positioned between them a relatively large thin stabilizer 4 which preferably rises vertically from said rear members of said side members I to simulate the tail of an aircraft. Y

.Mounted between the frame side members 3 and intermediate their ends is a bearing block I and in said bearing block is a nutted bolt 6 which rotatably secures a'propeller B to the bearing block and frame or fuselage A. The hub of the propeller B is in the form of a spool -'l which is suitably secured to the propeller blades I for rotation therewith. The spool 1 supports the propeller 'B somewhat above the frame A so that a cord 9 can be wound around said spool I. A handle in is secured to one end of the cord to permit said cord to be easily pulled from. the spool. Y

The outer ends of the propeller blade I are connected to a ring orband II which not only strengthens the blade unit and prevents the blades from being bent, but it also serves to protect the operator of the toy from becoming injured by the blades.

In operation the cord 9 is wrapped around the spool 1, the frame A is grasped in one hand and the handle l0 onthe cord 9 is grasped in the other hand. The cord 9 is then unwound from the spool 'l-with a sharp pull and at the same time the frame A is released. Rapid rotation of the propeller due to the pulling of the string 9 will lift the entireunit into the air. Of course, the cord 9 is completely unwound from the spool and remains in the operators hands.

By providing the stabilizer 4 on the frame A it has been found that said frame will not rotate to any great extent, and, consequently, a more realistic simulation of an actual aerial machine results.

I have shown the propeller B mounted on a vertical axis but it will be understood that the axis can be tipped forward slightly whereupon the device will have a forward and upward motion as distinguished from a substantially vertical movement-with the vertical axis shown in the drawing.

.- It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.

What is claimed is:

7 An aerial toy comprising, a frame made up of a pair of laterially spaced side members connected at their forward and rear ends, said side members being relatively thin, connections between said side members to produce a rearwardly streamlined or tapering form, one of the connections between said side members being located at the rear ends thereof and extending upwardly to provide a stabilizer, a propeller rotatably supported on a vertical axis intermediate the ends of said frame and substantially centraily thereof in a transverse direction, and said propeller including a hub in the form of a spool adapted to have-a spinning cord wound therearound.
