ARROW GLIDER Filed July 22, 1936 BY ATTORNEY. f

Patented Apr. 27, 1937 UNKTE STATES PATENT orrlcs 2 Claims.

This invention relates to toys and more particularly to a type of toy adapted to be hurled into the air, there to float and eventually glide to the earth.

An object of the invention is to provide a toy of this type having a body provided with normally closed wings, horizontal and vertical rudders and a catapult for initially driving the toy into the air.

A further feature is in the provision of means for causing the wings to spread automatically, when the body starts to descend, thereby becoming floatingly supported in the air.

Another purpose is to produce an arrow glider toy easily operated, fascinating in its evolutions in the air, and capable of affording a pleasurable out-of-doors entertainment.

These objects are accomplished by the novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawing, constituting an essential component of this disclosure, and in which:

Figure 1 is a top plan view of an embodiment of the invention in closed position ready for flight.

Figure 2 is a side elevational view thereof.

Figure 3 is another plan View showing the wings released and spread, as during flight.

Figure 4 is a perspective view of a form of catapult used in hurling the glider into the air.

Referring in greater detail to the drawing, the numeral I 5 designates in general a bar of considerable length and preferably of rectangular cross section.

Set transversely in the bar, near one end, is a 35 horizontal rudder I 6, extending uniformly outward at both ends, its front edge tapering from the center towards the ends.

A vertical rudder ll reaches upwardly from the bar above the horizontal rudder, as best seen in Figure 2.

A pair of wings it having semi-circular front ends, are reduced in width at their inner rear portions l9 and are of such length as to extend beyond the rear end of the bar I5, over the horizontal rudder l 6. v These wings, while duplicates, are pivoted in reversed position, one above the other to the bar I5, at their front portions, on the shank of a pin 20, passing through their fiat semicircular front ends, centrally of the bar and provided with an eye 2| at the opposite, lower side of the bar.

Fixed at its ends in the wings I 8, near the pivot 20 is an elastic member 22, such as a rubber cord or tension spring, the same acting to 55 draw the wings normally towards each other as shown in Figure 1, the bight or center of the elastic engaging a hook 23 in the bar.

This hook 23 extends upwardly through the bar I5 and is part of a wire elbow 24 adapted to engage a catapult in hurling the glider aloft and contact the ground when landing; a continuation of the wire forms a loop 25 passing over and around the extreme front end of the bar 15 and terminates in a catch 26 raised above the upper surface of the bar.

A cord 28 is secured at its ends in the wings l8, intermediate their length, the cord passing below the bar and through an eye 29, thence along the bar through the eye 2| to a ring 30 in which the bight of the cord is secured.

The length of the cord 28 is such as to permit its outer, ring secured end to be passed over and around the catch 26 when the wings are folded inwardly as seen in Figures 1 and 2, and are frictionally held in this position during the initial upward flight of the glider.

However, as the glider arrives at its highest point in the air, the glider becomes reversed in its longitudinal position, due to the center of gravity being rearward of the pivot 20, and, upon the bar l5 pointing downward, the ring and cord become freed from the catch 26, whereupon the wings open to the position shown in Figure 3 thereby acting to support the glider in the air for a considerable time.

In Figure 4 is shown one form of catapult, the same consisting of a handle bar 35, to one end of which is secured an elastic band 36, the bight of this rubber band being placed over the rear of the elbow 24, and the band sufliciently stressed to hurl the glider aloft when suddenly released.

Although the foregoing is descriptive of the best known embodiment of the device it will be understood that the appended claims are sufficiently broad to cover minor modifications and changes in construction as may be embraced by them.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:

1. A toy glider comprising an elongated bar constituting a body, a single pair of duplicate wings arranged in reversed position and pivoted in superposed relation on said bar at a point in advance of the center of its length, said wings having their rear portions reduced in area, a yielding connection drawing said wings into juxtaposition, non-elastic cords adapted to spread the wings, means to normally retain said cords inoperative, and means to release the retaining means upon a reversal of direction of movement of said bar.

2. A toy glider comprising a single bar, a pair of wings connected by a pivot common to both to said bar in advance of its center of gravity, said Wings reduced in width at their outer portions, an elastic member retaining said Wings in folded position, eyes set in said bar, a cord attached at its ends to each wing and passing through said eyes, a catch on said bar to engage said cord when said bar is pointed vertically upward, said cord becoming automatically released from said catch when the direction of said bar is reversed, horizontal and vertical rudders on said bar, and a ground contact element carried by said bar.
