l Application tiled September 23, 19E-8. Serial No. 454.392.

To all 4zrtom Zi may conce-rn:

Be it known that l, FRED D. B mxrs, a citizen of the Tfnited bltates. residing in the cit v of Milwaukee. county of Milwaukee,

5 and State of 'sconsin, have invented eertain new and useful Improvements in Parachute-Guns, of which -the' follo\ving r is a specification.

This invention relates to improvements in parachute guns and has' among iis salient objects to provide a construction in which a parachute is automatic-all)v shot. or ejected from a/cross-how gun; to provide a novel construction of the parachute proper which more etl'ectivel insures the opening of the latter duringA it: descent; to provide novel details of construction and arrangementr for etting' the gun and for dist-l:urgingthe parachute: to provide a simple and reliable 2O device which can he readily' and safely operated by a child and which can be manufactured at a low cost; and in general to provide an improved eonftruction of the character referred t: i-

The invention consists in the matters hereinafter deseriht-l and more particularly pointed out in the appended claim.

Referring to the drawings. Figure l shows i. s de tlevatic-n of my improved crossbow gun, the set position of the `:gun heilig shown. in dotted lines, Fig. 2 i. a fragmentary side elevation of the gun taken at right angles to the vievv shown in Pig. l. Fig. is a transverse .sectional view taken on lines of Fig. l and lookingr in the direction of the arrows: Fig. l is a side view of the parachute in closed position, parts heilig broken avvaiv to reduce the size of the drawing'. l: is a .similar view on 40 a smaller scale showing the parachute in open position. Fig. G is a sectional detail view showing the @instruction of the lower weighted end of the parachute. Fir. T if :t fragmentary top plan view of the device 4 with'the paraehute arrow removed.

as a whole the barrel of thegun which consiStS essentially of a splity metal tuile eom- 9 9. respectivel): lhe

end of the parts i- Q' telescope within and are secured to a tumlar .sleeve 5. O

Upon each side or the sleeve o 1s mounted a bzw-sprlne` 7. each bow-spring consist-mg in the preferred construction shown of a length of spring wire doubled hack upon itself at its outer end, eat-h half provided with one or more coils or 'turns S adjacent to the side of the barrel and the terminal portion S' inserted downwardl)` and fastened within a suitable socket 1'. It will he understood that the two halves of each hor.- spriug are. alike and extend substantially parallel with each other throughout.

To the outer ends of the two springs is secured a how-string'. which preferably com prises sections of heavy rubber or elastic cord at each end, and .-t middle portion of non-elastic cord l0, which latter extends through the slot between the divided halves of the barrel. The lower edge of the sleeve .3 serves to arrest the outward movement of the how-ftring and is suitahlv rounded to prerent cutting the latter. The elasticity of the eord sections 9 is supplementary to the re-iiiencv ot' the how, and furthermore enables mue-h shorter how-springs to he used than would he the case were the bow-string 1iunelastic.

in order to hold the how in set position. th. end ofthe handle or stock inside the tube or barrel carries a wire detent.V 11 eecured t', the stoel; h v means of a stud or bolt l2. The engaging' end of this detent is desirnhly U-shapednnd extends trrutsverselv of the slot between the halves1 ot the barrel. as shown elearl)v in Fig. 2. ll'heu the`how flexed the how-string is hooked over orheneath the detent 1l. In order to lire the gun. a trigger 13 is provided, which takes the form of a bent lever pivoted about mid-length as at 1l between the ears of a bracket 15 suitably secured to the side of the stock. The upper end of the trigger is bentto extend. through an aperture 16 and through the U-shaped portion of the detent. while the opposite end of the lever norl l l lnail'v stands ohliquely outwardly away from the stock, as indicated at 17. By prt-ing the exposed end of the trigger inwardly, the how-spring is forced ot` from the deteut and the bow released.

Defrihng, now, the parachute, designated as a whole 1S, it comprises an arrowlili-: body 19, to the upper end of which is secured the cover or fabric 20, a slide-ring 2l mounted upon the -arrow body and to which the lower ends of the stay-strings 22 are connected, and a notched member 23 upon the lower end of the arrow- The parachute fabric is desirably of light silk or analogous readily tiexible fabric, and may be conveniently fastened to the upper end of the arrowr by an encircling ring or hand 5 Q4.' The strings 22 may be .simply tied onto the peripheral edges of the fabric at regular Spaced apart intervals, and in order to limit the upward movement of the Slidcring, and thus hold the parachute in properly distended form, a stop 25 is provided on the side of the arrow at a suitable point. The notched member in the preferred embodiment shown consists of a soft or semi-sott rubber elongated cap, provided' at its open end with an inturned bead or constrictivc part- QG which engagea a `auitable annular groove 27 in the end of the arrow, and so holdsV the cap attached thereto. Inside ot` the cap is provided a weight QS which is made just heavyenough to insure the prompt righting of the parachute after ithas reached .its maximum height after being shot. so as to insure the prompt opening of the device. The notched member 23 is also 25 provided with integral wings Q9 which deand adjusted so that the notch of the arrow straddles the bow string and rests upon the latte]` or detent. The length of the arrow below the loweet point to which the slideringr descends is desirablv equal to. or

Slightly zgreater than, the length of the barrelfrom its discharge end to the detent, so that the slide-ringlr docs not enter the barrel. The device is shot like an ordinary cross-bow. being usually, of course, directed .40 vertically upward.

As an improved detail of construction, I' provide upon the discharge end of the barrel an outstanding prong 3 ot suitable toe upon the same when the end of the barrel is rested against. the ground, thua enabling; him tohold the gun down while he draws; up the how-string with both hands. lt is thus optional to the operator whether he places the hutt ot' the stock against his body and Seta the bou.l by pulling the string toward him. or placers the muzzle of the gun upon the ground, and holding: it down with his toc. pulls the bow-string up\\'ardl v.

lt will bc understood from thc foregoing;r description that a devil-e cmlmdyiu;r my invention may be nnuulfacturcd at low cost, that it is a to v which is peculiarl)v attractive and instructive to. children. and that the several objects o" the invention stated are fully accomplished.

`While the device herein shown constitutes a preferred embodiment of in v invention, it is, of course. apparent that. the details,l of construction ma)v be varied without departing from the spirit of the invention.

I claim as in v invention:

The combination with a parachute arrow,

elongated cap shaped forked notch mem' ber telescoped upon the buttend of the arrow and a weight within said notch member.
