stood that the glider of Fig. 2 is conditioned for flight by stretching the rubber band IS in a rearward direction until the end 2| thereof may be inserted into slit 24, thereby to advance the weight 22 to the nose of the glider body as indicated, against the opposing force of the stretched rubber band 25. Upon thusly conditioning the glider for projection, the operator may squeeze the slit 24 together for clamping the rubber band end 2| against slippage through the slit, while at the same time a sling or projector such as is indicated in Fig. 8, may be applied to the stationary hook in readiness to send the glider; in flight. It is to be expressly understood that j the projector shown in Fig. 8 is merely one example of a suitable projector that may be used for the purpose just explained, and as such, it may comprise a wooden handle 3| with a strong rubber band 32 secured to one end of the handle in any suitable manner. The particular manner of attaching the rubber'band 32 as shown in Fig. 8, consists in furnishing the upper end of the handle with a transverse slit 33 terminating in'a bore 34 wherein the rubber band permanently rests. By applying the looped end 35 of the band to the hook 30 of the glider body and holding the glider in one hand while the handle 3| is held in the other hand, the band 32 may be stretched, and the glider subsequently released so 'as to result in projection of the glider high in the air. As the glider approaches its maximum height, the free end 2 I of the rubber band slowly slips through the slit 24, andbefore the glider has completed its descent, the band end 2| will have left the slit, permitting the band 25 to retract the weight 22 for changing the center of gravity of the glider, thereby causing the glider to stunt as it descends. The release of the weight 22 as above explained may be timed by permitting more or less of the band end'2l to protrude from the slit, and the character of stunt performed will depend upon the location of theknot or -stop 28, and the strength or the tension of therubber band 25.

By. anchoring the pulley I! so that it may not rotate upon the. axle 3,, a different stunting effect may be obtained, for then the movement of the weight 22 rearwardly when the rubber band end 2! is released from the slit, will be slow or gradual, and it will accordingly be appreciated that the. gradually shifting center of gravity thereby resulting will gradually or progressively It is to be equivalent of a rounded integral nose on the The foregoing fully explains the principle of the'operation of the improved glider toy, and the same principle is employed in themodified forms of the device disclosed in Figs. 3, 4, and 5. It may here be; stated that the rubbers 25 and I9 mayhave substituted therefor a single rubber anchored to the weight in the manner disclosed in Fig. 5. By using the Fig. 5 type of anchorage, the position of the weight along the rubber may be. changed. at will, for determining the glider maneuvers, which in allcases depend upon the shifting center of gravity as influenced by th weight.

- =In the modification of Fig. 3, the character 3 5 indicates an endless rubber band which loops into 'a notch 31 at the tail of the glider, the opposite reaches of the band lying at opposite'sides of the The remaining loop at the opposite .lodged from the notch 41. advantage in disposing the weight directly upon end 38 of this band receives a loop 39 of a length of rubber 40 which is not endless. One end 4 I of rubber band40 is clampedat 42 upon the top of a slidable or shiftable weight 43, the details of which are clearly shown in Fig. 6. The opposite end 44 of rubber band 40 has a knot or stop at 45, which may not pass through a Wire loop 46 which is supported by a glider body in the manner disclosed in Fig. 7. An intermediate portion 48 of the rubber band 40 is anchored relative to the slidable weight.

The relationship of the parts as disclosed in Fig. 3, is the relationship existing while the glider is descending and stunting,.or the relationship in .which the parts will be found upon completion of the flight.

To prepare the glider of Fig. 3 for flight, the

, operator grasps the rubber band end 44 and pulls downwardly until the weight 43 is slid forwardly to the nose of the glider, whereupon the end 44 is moved upwardly over-the top edge of the glider body and stretched until the free end 44 may be inserted into the notch 41 of the rudder. The relationship of the parts will then be as disclosed in Fig. 4. The rubber band end 44 (Fig. 4) will gradually slowly slip from the notch, and when it does, the knot or abutment 45 will snap forwardly to a position against the wire loop 46, while at the same time the weight 43 will be influenced by the weight 43 to substantially a position corresponding to the position of weight 22 in Fig. 2. There is an advantage, however, in advancing the weight over the nose of the glider, so that the weight rests upon the flattened surface 48 as disclosed in Fig. 4, the advantage being that the weight will protect the glider. against damage in the event that-itlands nose first against a hard object before the slipping end 44 of the rubber band 40 has had an opportunity to become dis- There' is a second the nose of the glider body, and that is that greater distance or height can be obtained by the glider when its center of gravity is located very close to the nose or advancing end of the glider body.

Referring now to Fig. 7, it may be noted that the nose of the glider may be grooved as at 49, if desired, for keeping the rubber band 40 in position thereon. Also, it should be noted, that the wire loop 46, whose pointed ends 50 may be driven into the material of the glider body, provides also a hook portion 5| to be engaged by the loop at 35 of the projector shown in Fig. 8, when it is desired to put the glider into flight.

With reference to Fig. 6, it may be noted that weight 43 may comprise a metallic stool 52 having ,spacecl depending legs 53 providing a channel for reception of the upper edge of the glider body, and upon the flat top of the stool may be fastened the weight 43. It has been found that the element 43 may be constructed of rubber, and that an endless rubber band of small size, indicated at 54 may be crossed upon the weight and held to the stool by passing the rubber band over the weightand beneath the outwardly extending flanges 55 of the stool. Thefree end 4| of rubber band 40 may be anchored to the weight by passing I glider body.

' assess? it beneath the rubber band 54, and slippage may be prevented by suitable roughing or corrugatin'g of the upper face of the weight, as indicatedat The character '51 of Fig. 6 indicates how'the aspect of the invention; For example, it is iinma 'terial how the weight is attached to the stool, or

how the rubber band connections to the weight are effectedj nor is it even necessary that the weight- '43 be a separate piece rather than an integral part of the stool 52L The details of the wire loop 16 of Fig. '7 likewise maybe altered, and especially might the loop portion of the wirebe made separately from the hook portion. 51 thereof, as might be "suggested by observing the nose end of the glider disclosed in Fig. 5; .f o

Inthe modified form of the device disclosed in Fig. 5, the nose of the glidermay be-provided with a wire loop 58 adapted to receive slidingly "therethrough, a rubber band 59. One end 60 of the rubber band is anchored near the tail of the The opposite end of said rubber band is indicated at 6 I. the eye 58, a knot or other abutment 62 is app-iied to the rubber band. Between the eye 53 and the anchored end 60 of the rubber band,

the weight '63 is attached. Weight 63 is adapted to slide along the upper edge'fid of the glider body, and it may straddle said edge as previously explained in connection with Fig. 6; The anchcrage between the weight 53 and the rubber band 59, may be 'efiected by piercing the weight at its upper corners and threading the rubber band therethrough asshow'n. v 1

To conditiontheFig. 5 glider for flight, it is necessary only to stretch the end Bl rearwardly until it maybe lodged, in the notch l"! of the rudder, as, indicated by the broken line. CSuch v stretching of the rubber band will of course advance the weight 53 to the nose of the glider body, perhaps very close to the eye 58, and as explained in connection with the other drawing figures, the glider then-may be projected 'by applying "the projector of Fig. 8 to the hook 6 1. When the end 6! finaily slowly slips through the notch 41 in the rudder, the portion, 65 of the rubber band will act uponthe weight to retract it to the position-indicated by Fig. 5, at which. position the knot or abutment 62' will be stopped by the eye 58.

From the foregoing, will be noted that every form of the glider illustrated and described herein depends, for its maneuvering functiorn-upon the slipping of a rubber band end/slowly and progressively through a notch or other frictional holding means which holds "the rubber band end just tightly enough to preclude rapid dis lodgementthereof. A' child operating, 'thedevice may'obtain various efiects by allowing either lit-- *tle or much of the rubber band end 44 to extend through the frictional holding means- 41', thereby to time the delayed action of the weightmovement. Varying eiiects may also be had by changing the location of the knot or abutment.

in each instance, or by applying rubber bands having different tension characteristics. Other 'efiects may be obtained, for example by ihcreasing or decreasing the-length of the rubber band en'd l-l (Fig. 3) by adjustingit through the clasp Between the end 6| andstructions wherein the wings are adapted for shifting movement "bodily along the axis of the spends to the weight '22 of Fig. 2, is adapted to 10.

be located upon the nose of the glider in the manner of :4. To explainafurther, the character i'td discloses a-rubberiband having one end an- .c'horedat tl near the tail of the glider, while the opposite-end 58 has been passed through an 18 eyelet 69 at thenose of the glider. A knot or other suitable stop 15] is provided between the eyelet and the-extreme end 68 of the rubber band. Intermediate the ends of the band, the weight 43 is fixed to the'band; and said Weight is siidable 40 as in the other forms of the invention. To conidition the Fig. '9 device for flight, the operator need only stretch the end 68 rearwardly to-the tailyand engage itwithin the II, from which said end can slowly slip in the'manner, heretofore explained. 'While the end 68 is held within the notch, the weight will be disposed directly upon the fiat nose 12 of the glider body, in substantially" the manner of Fig. l. In so disposing the 'welghtit'will of course :have to be boosted over the projecting hook '53, but when the end 68 leaves the hoiding notch H the weight will leave the nose I? and jump over the projecting hook to the positionindicated in Fig. 9. The knot or stop it! cannot pass through the eye 69. It should be particularly noted that Fig. 9 may be made to operate in the manner, explained. in connection with Fig. 2, by merely making H the permanen't anchorage for the end 68 of the rubber,

and p-rovidingfor the "delayed frictional release at the :point 6?, as disclosed at M of Fig. 2. Thusly modified, the weight 43 of Fig. 9 will be disposed along the'topedge of the glider body, as in Fig. 2, and gthe eyelet 69 will be located at the point A, all of whichamounts to a mere m "reversal of .parts' capable of performing the function intended according to the present invention. "Ihevarious forms of the invention disclosed herein are not to be confused with glider conaglider body, sincefsuch constructions are clearly inferior from the, standpoint of durability and simplicity. Although in the various disclosures of the drawing, the weights are shown as being- M5 'slidable along the body, it should be understood that such weights may be mountedpivotally or otherwise, so lo'ngasthey may be considered 'shiftab'le toward and from the nose of the glider body. Y

In. the Fig; 4 discloure, it should be noted that accuracy'of disclosure has been sacrificed to obtain clarity. by showing the various rubber banlis apparently unsupported upon the nose of the-goder. Actually, of course, the portions of 65 the rubber bands shown forwardly ofthe weight 33 in 4. will rest directly upon the weight, instead of being spaced therefrom as drawn in the interest of clarity. If the rubber bands be manipuia ed was explained previously for con- &0

the glider for 'fiight,'proper operation re'd,although the various reaches of the rub er bands will-rest closely adjacent or upon mother, both at the front or the glider and ralgng the top edge thereof. In each instance,

the top edge of the glider body is indicated generally by the character 23.

, In the construction illustrated by Fig. 9, the weight 43 performs an added function, which is that of furnishing a buffer or resilient landing gear. When the glider lands substantially horizontally, the weight will contact the landing Surface with a yieldingly frictional engagement, thereby effectively arresting the forward movement of the glider without injury to the parts.

It is to be understood that various modifications and changes in structural details of the vaing means, to delay shifting of the weight by said yielding means until the glider reaches a predetermined stage of its flight course.

In a glider toy, the combination of a winged body having a nose and a tail, a weight shiftably mounted upon the body, including means for yieldingly urging the weight into movement from the nose region toward the tail region of the glider body, and time delay means for temporarily restraining the weight against such movement, for a limited time during the flight of the glider toy.

3. In. a glider comprising a winged body having opposed edges, a nose, and a tail portion, the combination which comprises a weight shiftably supported for movement relative to the body from the region of the nose toward the tail region thereof, an elastic weight shifting element having opposite ends and an intermediate portion, said weight being anchored to the intermediate portion of the weight shifting element, means anchoring one end of the weight shifting element to the body near the tail region thereof with said end extending along one edge of the glider body, and means releasably holding the other end of said weight shifting element, when stretched, in position along the opposite edge of the glider body, for establishing the position of the weight with respect to thelength of the glider body, said 'releasably holding means constituting a timer for release of the weight to the contractile action of the stretched anchored end of the elastic Weight shifting element, for delayed shifting of the weight.

4. In a glider, the combination of a winged body having opposed edges, a nose, and a tail portion, a weight slidable along one edge of the body from the region of the nose toward the tail portion of the body, an elastic rubber element secured to the weight and to the body tending always to urge the weight in the direction of the tail portion, and a second elastic rubber element secured to the weight, said second element having a free end stretchable in a direction opposing the direction of movement of the weight imposed by the first elastic element, and a slipping anchorage means on the glider for insecurely anchoring said free end of the second elastic element, to eventually release the weight to the weight-moving influence of the first elastic element, for delayed shifting of the weight.

5. In a glider, the combination of a winged body having a nose and a tail portion, a weight shiftable from the region of the nose toward the tail of the glider body, means on the extreme front of the glider nose for supporting the weight in position to receive impacts occasioned by headon collision of the glider with an object in its path of flight, and a time-delay means self-op erative normally during flight, for shifting the weight from its position of rest upon the glider nose, toward the tail portion of the glider body.

6. In a glider, the combination of a winged body having a nose and a tail portion, a weight shiftable from the region of the nose toward the tail of the glider body, means on the extreme frontof the glider nose for supporting the weight in position to receive impacts occasioned by headon collision of the glider with an object in its path of flight, and a time-delay means self-operative normally during flight, for shifting the weight from its position of rest upon the glider nose, toward the tail portion of the glider body, and means for limiting the extent of such weight movement.
