TOY GLIDER AND CARRIER Filed March 22, 1940 2 SheetsSheet 2 Patented Jan. 14, 1941 v UNITED STATES PATENT OFFICE 6 .Claims.

My invention consists in new and .useful improvements in a toy glider and releasing carrier for use in connection with kites and. the like and has for its object to provide a. simple con- 5 struction whereby a glider may be elevated to a predetermined point on a kite string and automatically released to slowly glide to the ground.

Another object is to provide a glider wherein the angle of incidence of the wings may be adjusted for elevating the carrier and glider on a kite string.

A further object of my invention resides in the novel construction of spring tensioned pivoted wings on the glider which cooperate with a supporting rack on the carrier to simultaneously catapult the glider into the air and adjust the wings for flight upon the operation of an automatic releasing means.

A still further object of the invention is to provide a novel latch mechanism on the carrier releasable by a suitable abutment arranged at a predetermined point on the kite string.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel features hereinafter set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

Referring to the drawings in which numerals of like character designate similar parts throughout the several views,

Fig. '7 is a sectional view taken on line 1- I of Fig. 2, and

Fig. 8 is a fragmentary plan view showing the locking means on the latch bar of the carrier.

In the drawings, I represents the body of my improved glider which is preferably constructed of balsa wood or other light material and is more or less streamlined in the conventional manner as clearly shown in Fig. l. The wing assembly designated generally by the numeral 2 consists of a pair of wings 3 preferably of balsa wood,

5 secured at their inner extremities to a saddle member which straddles the upper edge of the body I and is pivotally secured to the latter by any suitable means. In the form shown in the drawings, this wing supporting saddle consistsof a pair of transversely spaced vertical legs 5 formed of light metal, the upper edges of which terminate in oppositely disposed outwardly bent flanges 4 to which the inner extremities of the wings 3 are cemented or otherwise secured. The vertical legs 5 are joined together and maintained in the proper spaced relationby a relatively narrow strip of metal 5' which extends across the upper faces of the flanges 4 at their forward ends and is rigidly secured thereto. The saddle is pivotally-mounted adjacent the upper edge of the body I by a cotter pin 6 which extends through opposite openings in the vertical legs 5, a short metallic sleeve bearing I being provided in the body I to facilitate freedom of rotary movement.

As will be seen from Figs. 3 and 6, the flanges 4 of the saddle are arranged at such an angle that the wings 3 extend slightly upwardly towards their tips'for the purpose hereinafter set forth.

The wing assembly 2 is normally retained in flying position by any suitable spring means, that shown in the drawings consisting of a length of resilient wire 8 secured to the forward end of the body by small staples 9, its free end being tensioned over a lug II] projecting from the outer side'of the adjacent saddle leg 5, whereby the saddle and the wings supported thereby are retained substantially in a horizontal plane as shown in Fig. 5.

'I'hesaddle is rotatable about the pivot pin 6 against the tension of the spring 8, the space between the legs 5 disposed rearwardly of the cross piece 5 forming an elongated clearance II (Fig; 4) which extends to the rear end of the saddle, to accommodate the thickness of the body This rotation is limited by any suitable stop or abutment I2 (Fig. 5) arranged at a predetermined point on one side of the body I in the line of movement of. the saddle over said body.

The rear portion of the body I is provided with the conventional rudder l3 and elevator I4 which are also preferably constructed of balsa wood or other suitable light material.

I6 represents the main supporting strip or body of a carrier also preferably composed chiefly of balsa wood or the like, said body carrying a longitudinally slidable latch bar I1, one end of which extends beyond the adjacent end of the I when the wing assembly is rotated on its axis.

main strip [6 and serves as an abutment l8 as will hereinafter appear. The members I8 and. I!

are retained in this sliding relation by suitably shaped loops of wire I9, the free end of which 5 terminate in helical carrier guides 20 which are arranged in longitudinal alignment adjacent the outer face of the latch bar I1 so as to receive the kite string.

At longitudinally spaced points in the strip I6, I provide openings 2| adapted to receive the ends of similarly spaced carrier hooks 22 secured to and extending .upwardly from the body of the glider. The latch bar I! is provided with longitudinal slots 23 spaced to register with the openings 2|. At one end of each slot 23 and extending slightly into the slot is a locking pin 24 fixed to the latch bar I! and movable therewith, said locking pins being adapted to span the respective openings 2| in the strip [6 when the latch bar H is moved to its extreme forward position which is determined by a transverse stop pin 25 at one end of the latch bar arranged to abut the adjacent wire loop Ill. The rearward movement of the latch bar I! is limited by a stop pin or abutment 26 located in the upper face of the strip I6 in line withthe rear end of the latch bar.

Thus, when the carrier hooks 22 are inserted through the respective openings 2| in the strip it, their ends are disposed transversely in the 3 slots 23 and when the latch bar n is slid forwardly to its extreme position, the pins 24 engage the respective carrier hooks.

When the glider is placed on the carrier, the wing assembly 2 is rotated to its limiting stop l2 and is retained in this position by an angularly disposed wing rack 21 on the carrier. As shown in Fig. 1, this wing rack consists of a pair of transversely spaced arms secured at one end to the main strip I6 of the carrier and preferably ,40 reinforced by a brace member 28 interposed bei tween the two arms and secured to one edge of the strip Hi. The arms 21 are adapted to straddle the body I of the glider and engage the upper surfaces of respective wings to hold the same at the 45 proper angle of incidence against the tension of the spring 8 when the lock pins 24 are in looking engagement with the carrier hooks 22.

Having described the construction of my improved glider and carrier, its use and operation 5 are as follows:

' As heretofore mentioned, this device is for use in connection with conventional kites and the like, although it may be used with an string or cord depending from an aerial support to the ground. For the purpose of illustration, however, we will assume that a kite has been flown to a predetermined elevation, the kite string being represented by the numeral 29 in Fig. 1. A suitable stop or abutment 30, which may be in the form of a cork, is fixed to the kite string at any desired distance from the ground. The carrier is first slidably mounted on the string 29 with the projection 18 on the latch bar H directed upwardly. It will be noted that due to the shape of 6 the guides 28, it is not necessary to thread the string from its end, it being possible to apply the guides at any point on the string by simply twisting the string into the convolutions of the guides. The wing assembly of the glider is then tilted 70 or rotated on its pivot pin 6 against the tension of spring 8 until the saddle legs 5 abut the stop 12 and while in this position the glider is placed on the carrier with the upper surface of the wings in engagement with the inclined wing rack 21, 75 the latter straddling the body portion I. During this operation, the latch bar I! has been retracted to its rearmost position so as to clear the openings 2| in the strip 16 for the reception of the carrier hooks 22, and when these hooks have reached the slots 23 in the latch bar, the latter is slid forwardly so as to bring the locking pins 24 into locking engagement with the ends of the respective car- .rier hooks.

The tension of the spring 8 on the projecting lug ID of the saddleleg 5 tends to return the wings to their original horizontal or flying position and in so doing, causes a pressure to be exerted on the upper surface of the wing rack 21 and in turn on the carrier hooks and locking pins, thus developing sufficient friction on the pins 24 to prevent accidental dislodgment.

Due to the adjusted angle of incidence of the wing assembly with respect to the body I, while locked in this position, as well as the relative angle, or the angle of dihedral of the individual wings, a lifting surface is provided whereby .the glider and carrier are caused to travel upwardly on the kite string by the force of the wind or currents of air, and when the projecting end l8 of the latch bar I! strikes the abutment 30 on the string 29, the latch bar is forced rearwardly, withdrawing the locking pins 24 from the hooks 22. Immediately upon the release of the carrier hooks, the spring 8 forcibly returns the wing assembly to the substantially horizontal flying position of Fig. 5 and in so doin kicks or catapults the glider from the carrier into the air. The wing assembly having now returned to flying position, the glider floats slowly to earth. The carrier then descends on the kite stringby gravity and the operation is repeated for elevating the same or another glider.

From the foregoing it is believed that the construction and advantages of my invention may be readily understood by thoseskilled in the art without further description, it being borne in mind that numerous changes may be made in the details disclosed without departing from the spirit of my invention as set out in the following claims.
