BOOMERANCT THROWER.

` Application tied Juiy i 3,

To all whom t may concem Be it known that I, CARL A.. ANDERSON, a subject of the King of Sweden, residing at Boston, in the county of-Suffolk and -State of Massachusetts, have invented new andv useful Improvements in Boomerang Throwers, of which the following is a specification.

This invention relates to a boomerangthrowing device including `a flat-surfaced tablety adapted to support a boomerang in position to be thrown edgewise, a handle to be grasped by the operator, a spring adapted to bel set for action y byv the operator, means actuated by the spring to impart a forcible edgewise movement to al boomerang supported byy the tablet, and a trigger adapted to. releasably confine said` springactuatedV means, and permit the same to act on the boomerang'.

The invention is embodied in the improvements hereinafter described and claimed in a boomerang thrower characterized as above stated,`the objects attained by said'improvements being fully set forth hereinafter. i

Of the accompanying drawings forming a- 1 part of this specication,-

Figure 1 is a side view of a boomerang thrower embodying the invention.

Figure 2 is a top plan view of the same.

Figure 3'is an enlarged fragmentary section online 3-3 of Figure 2.

Figure 4 is a top plan view, the tablet beingA removed. v

Figure 5 is a side viewA of a portion of the boomerang shown `by dotted lines in Figures 1 and 2.

Figure 6 is a view similar to Figure 5, showing a modification. l

The saine reference characters indicate the same parts in all of the figures. l

In the drawings, 12 `represents a Hat tablet, preferably of sheet metal, secured to a holder which includes a .base portion on which the tablet is seated, bearings at one end of the base portion, and ahandle at the opposite end of` said portion. The holder is preferably formed from an elongated metal strip, bentv to form alooped` central portion 13, constituting the handle, parallel ,connected portions 14, riveted together at 15 (Figure 3)` and constitutingy the base portion, and end portions 15 and 16, bent downward from the base-forming portions 14, and provided with ears 17 and 18, which are apertured at 19 to form the bearings which are spacedl apart, as shown 1922,; serial No. 572,563.v

- by Figure 1. A rod`20 isjournaled in saidl fbearings, and is provided at its iipperend'V i with. providedat itsouter end with an upstandan angular arm 21,"bent yat 22, and,

ing finger 23. 24 represents a helicalsprinfr.

one end of which is'engaged at 25 with the end portion 16, andthe other end at 26, with the rod 20. A movement of theA arm 21 to the Vfull line starting position shown by Figures l, 2, and 4, compresses the spring, so that thevlatter'ten'ds to vforce the arm-to vthe dotted-'line stopping'position shown by vsaid figures. When the arm is in the starting position, the finger 23 projects across kone endof the tablet 12, and when the arm is inthe 'stopping position, the linger projects across the opposite endof the tablet. The arm g is releasably conned in its starting position by they trigger hereinafter described, and is arrested in its stopping position by` the end. portionl of the holder, vas shown by Figure 4.

The trigger is composed lof a` resilient strip 28, attached at29-to the handleportion 13, and a hooked terminal 30, attached tothe free end of the strip andnormally f i held bythe latter agains'tuone side ofthe arm 2l. handle portion 13, yand is arranged tol form a finger rest on which a finger of the hand The strip 28 extends beside the.

grasping the handle-may be `pressed to Inove-I Y the trigger in the direction of arrow Figl ure l), and thereby release the arm.

The tablet is-preferably secureddetachably tol the base portion ofthe holder, so that lthe tablet and holder rmayxbe separated and compactly stored. Tofthis end I employl bolts 32, linserted in coinciding holes I formed inthe tablet and in `the .base portion ofthe holder, said bolts `having heads 33,

bearing on the upper side of the tablet, and clamping wing nuts 34, engaging said bolts and bearing on the under side of the base portion ofthe holder.

To prevent obstruction of the `upper surface of the tablet by the bolt heads, I provide the tablet with bosses 36,forming de- Y pressed portions on which the bolt heads are seated, said heads being flush Vwith vthe up.-

per surface of the tablet, as shown byFigure 3. The bosses 36 maybe provided with slots 37, (Figure 2), arranged to .receive the` heads 33 (which are` oblong), whenithe heads are turned from the position shown by Figure 2, to coincide with thek slots. Thev tablet may, therefore, bev separated from the; f

holder without removing the bolts from the latter.

The rod 20 is loosely confined by the spring 24 in its bearings, so that it may be moved endwise when the tablet is detached. Provision is thus made for storingl the arm 21 beside the holder in the right-hand dotted line position shown by Figure 4. To locate the arm in this position, the rod 2O is first moved upwardin its bearings, until thev arm is free to swing across the holder, then swung in the direction of arrow jz/ (Figure 4) across the holder, and then moved downward to cause the spring, now under relatively slight tension, to hold the arm against the holder.

40 represents a boomerang, which is a thin angular strip of any suitable material, such as hard rubber, vulcanized fiber, etc., adapted to lie flat on the upper surface of the tablet. In oneend portion of the boomerang is an orifice 41, adapted to loosely receive the upstanding finger 23. When the arm 21 is confined in its starting position by the trigger, the boomerang is deposited on the tablet, its orice 41 receiving the Afinger 28. When the trigger is manipulated to release the arm 21, the linger and the boomerang are swung around to the stopping position of the finger. The tablet is provided with means for lifting the boomerang from the finger when the latter reaches or approaches its stopping position, saidmeans being preferably an inclined strip 43, arranged to force the` boomerang upward until it leaves the finger. The boomerang is now forcibly projected from the tablet, and has an orbital movement, causing it to move first away from the throwing instrument, and then return to the neighborhood thereof.

I am not limited to the employment of means on thel tablet for lifting the boomerang to disengage it from the finger 23. As shown by Figure 6, the boomerang may be provided with an open slot 42, which receives the linger when the latter is in its starting position. When the finger is released by the trigger, it bears on the edge of the slot 42, and imparts a whirling edge,- wise movement to the boomerang, until the arm approaches its stopping position, the slot then permitting the separation of the boomerang from the pin. It will be seen, therefore, that when the boomerang is provided with an opening, as the orifice 41, formed to surround the pin 23, lifting means, such as the incline 43, will be necessary, but when the opening is a slot 42, said lifting means will be omitted.
