to have self-adjustment. 1 ,Y Figs. 13 and 14 are vdetail viewsushowingfa modified form of connection between the selfadjustable wing and the cross piecerof the glider.

.Referring first to the glider this comprises'y a body part or stem 1, having a wing 2 mounted at its front end so as to have swing-` ing movement vertically or up and down relative to the body to accommodate itself automatically to varying air pressures. The

manner of mounting this wing so vas to swing about its frontedge kat 3 asv a pivot,V may be carried out 1n various ways. F1gs.i

for. looped about the crossjpiece andthe wing 5' as'shown, said bands being lodgedv in the notches to retain themyagainst displacement.

These bands hold the. wing to the Vcross piece but allow pivotal` movement,vertically-about o the front edge where it lies adjacent the cross piece and with'said front edge slightly abovewhich on itsypupper` side presents two upand forward of the edge'of the cross piece 8.V The rear edge ofthe fwingjlies adjacent y a shoulder 1() onthebody whichfshoulder furnishes an abutment which receives -the initial backwardk Athrust ofthe wing when the* glider is first projected fromthe gun.

- and as the `wingis attached to the cross head by the yielding vrubber bands it would recede from its prescribedposition when it is first projected 'were 'the shoulder not provided to i l resist this action. This action would be ldue tothe comparatively severe banking of the air in front of the wing at the beginningof the gliders flight but withthe shoulder as Y a part of the 'structure any tendency for the. wing'toyie'ld backwardly as a whole will be. resisted by its rear Vedge'coming againstLt-he shoulder.:` yAftenthe initial impact` of the Vwing against` the air is pastthenlthefwing,

under the reactionof the rubber bands,` will; free its rear-edgeV slightly from contact with the shoulderand the wing then willbe vfree to rise and-fall at its rear part-relative to the bodyaccording as-the variations in the banking of the air takes place, or in otherV words, the wing will have self-,adjustment by a4 swinging movement aboutits front'edge according to the varying air `resistances which it meets4 in its flight. This self-adjust able wingzcontrols the -'light and causes `this to take place substantially straight in the dia rection in which the glider is projected. {It prevents the glider from performing a sharp upward curveor'loop at the-startbecause it yields `,to the comparatively excessive air pressure onthe initial stage of the flight. As the flight progresses thewing will rise and fall pivotally relative to the body of thev 1 glider as meets varying air resistances. j

CTI

The body 1 of the glider being in the form of a comparatively thin rod it follows that the shoulder is not extensive and is normally spaced apart from the edge if the wing, and therefore should the glider land onl the end of the wing it will yield on that end away from the'cross piece and vthus damage to the j wing will be prevented.

This yielding action'will be due k.to thek elasticity of the rubber'band.

In order to apply varying yieldable 'pres-Y sure to the wing for pressing it downwardly a rubber cord or short length of rubber 11 is used attached by abroad headedtack 12' to the glider body or stem and having its other end passing beneath a rubber band 13 so that by pulling upon this end 14 the rubber strip 11 will be strained and added, though yielding, resistance to the upward swing of the wing will be applied. The band 13 is wrapped'a number of :times about the 'body of the glider. To reduce thetension on the wing the rubber strip 11 is vpulled,

` backward through the band 13;VVV

Instead of connecting the :cross piece rigidly tothe glider body it may be yieldingly connected thereto by a rubber band 15, Figs. 8, 9, 10 and 11, and the wing instead of being Y connected to the cross piece by rubber bands maybe connected thereto by tapes 16Fig. 8.

In this instance, ifk the wing lands upon one Lend the whole organization including the wing and the cross piece will yield and no damage will result, this being due to the yielding of the rubber band 15 connecting the head orcross piece with the glider stem barrel 2O groove/d lengthwise at 21, notched at its upper side at 22 and provided with an insert piece at 23 extending across the gun and closing the rear end ofv theV groove 21.l

., A trigger 24 is pivoted at'25 said trigger member is comparatively thin.

consistingfof a sheet metal or other suitable piece lying against the side of the gun and having a plate-like extension'26, Fig. 4, lying inthe recess 22, and just in rear ofthe insert or shoulder 23. For `propelling the glider an elastic member consisting in part Y of a flat rubber piece 27 extends through any one of a series of notches V28 arranged along the lower side of the gun and the rear portion 29 of this band or loop engages a shoulder' 30 facing'rearwardly of the glider and forming a part of a hn or guide member 31 extending down from the bottoni face of the body of the glider. This fin or guide j It runs in the groove 21 of the gun and it extends lengthwise and centrally of the lower face of the glider body or stem.

This iin also has a. shoulder 32 facing forwardly and located in rear of the shoulder 30 and spaced apart therefrom.

In cooking the toy the glider is inserted with its guide iins 31, 31a, in the groove of the gun and with the propelling band portion 29 engaging the shoulder 30 and by drawing the glider backward along the gun its shoulder 32 is made to engage the insert shoulder piece 23 as shown in Fig. 1. When this has been done the elastic propelling band 27, 29 will have been stretched to the prescribed degree to place strong propelling force upon the glider and the device now is in cocked condition ready/to be operated to project the glider into space as a result ofthe reaction of the rubber band when the glider is released; For releasing the' glider the trigger is pulled which causes the plate-like part 26 thereof to lift the rear end of the gliderhigh enough to disengage it from the inset-shoulder 23, whereupon` the elastic will exert its force and project the glider from the gun. t willl bernoticed that when the device is cocked the body ofV the glider extends in an upwardly and .rearwardly inclined position relative to the upper surface of the gun so thatthe glider at its Vrear portion is spaced apart from the gun. This space receives the portion 29 of the propelling band which extends along this space to the shoulder 30l with which it engages. the other parts is important. It is below the glider body some distance forward of the rear endV thereof and it lies forward ofand spaced` apart `from the cocking shoulder 32 of the glider. By reason of this relation and the downward trend of the elastic from the shoulder 30 to the notch 28, the pull of said elastic is slightly downward and is applied at a point forward of the cooking shoulder and forward of the rear end of the glider body. As a result there will be no tendency for the'pull of the elastic to cock up the glider relative to the gun but the glider will be projected in the direction' of its body/or of its general lie relative to the gun.

The vseveral notches 28 are providedrso i that the child may adjust the propelling force to his strength sothat hemay readilyv cock the gun; v Y

The principle of the' selfadjustable wing may becarried out in connection with the rear wing if'desired. rIhis is illustrated in Figj12 in whichthe wing 2a is normally held in its uppermost position, i. e., inclin` ing upwardly and backwardly from the cross piece 4a. It is held up by a rubber cord 11a against va stop 33.

I claim: Y
