10 Claims. (c

Our invention relates to improvements in bows and particularly to a bow for propelling an arrow.

An important objectof the invention is to provide in a device'of the above character a nonbendable bow. r

Another object of the invention is to provide 1. 124-23) 1 'vided with oppositely disposed ends constructed like the connectors It whichco'rnprise the ball nose 2!! and shank 2| to which the other ends of the elastic tubesli are fastened by means of an improved rigid bow and a loop or. endless connection embodying elastics girdling the bow for propelling the arrow.

A further object of the invention is to providean improved anchorage and roller guides for mounting the endless connection on the bow frame. 7 f g A still further object of the invention is to pro-- vide an improved bow and hand grip therefor adapted for shooting arrows ofi center in relation to the bow.

Yet another object of the invention is to provide an improved combination cord and elastic means for propelling an arrow from the bow.

Otherobjects, features, and advantages of invention will also hereinafter appear.

In the drawing wherein is shown a preferred embodiment of the invention as now has been reduced to practice:

Fig. 1 is a perspective view of the device,

Fig. 2 is a fragmentary section in side elevation,

Fig. 3 is a section taken on line 3-3 of Fig. 2, and

Fig. 4 is a sectional detail of one of the ends.

Referring in detail to the drawing, the general parts of the invention comprise a rigid frame i, an endless connection 2 for encompassing the frame in an endwise manner, an anchor 3 included in the endless connection for positioning the latter on the frame, and a hand grip 4 fastenedto the frame for enclosing said anchor.

The frame I is of arched construction having a straight hand clutch portion 5 at the crest of the arch and symmetrical fore and aft end portions 6 and l.

At the terminus of each portion, 6 and l are provided rollers 8 and 9 respectively over which the endless connection 2 operates, said rollers being mounted in bifurcations 10 on shafts ll journalled in the branches forming said bifurcations.

The connection 2 comprises the cord l2 having its end portions fastened in eyes l3 of each of the connectors M. The connectors M are each in turn fastened in the ends of the elastic tubes l5 by means of a semi-spherical ball nose It and shank I! about which the band I8 is clamped to grip the tube to said shank.

The anchor 3 has its cylindrical stock I9 prothe metal clamping bands 22. The anchor 3 further includes a pin 23 fastened in the'midlengthportion of the stock [9, said pin extending within the hole 24 in the frame for keying the anchor 3 to the frame.

The hand grip 4 is for the most part U-shaped in cross section, it being applied to the clutch portion 5 by screws 25. Guide-ways 25 are provided on opposite sides of the hand grip for positioning the arrows incident to shooting them. Said guide-ways are spaced properly so that no matter in which position the bow is held either by a left or right handed person, the off-center propelling position of the guide-way will be a cue to the archer in determining the manner of holding his arrow relative to the bow.

By removing the hand grip 4, the propelling connections may be detached from the bow as a whole simply by pulling the cord off the pulleys. Hence, the propelling apparatus; that is to say, the anchor, cord, and elastics, mayconstitute a separate unit, an article of manufacture separately salable in the trade and may be purchased after the original parts have become too worn for further use.

The frame I is provided with a U-shaped tapering slot or groove 2'! in which the anchor l9 and elastics l5 are housed. When the cord I2 is pulled, the elastics l5 elongate in a straight line and do not frictionally engage said groove because of the end portions 6 and I being curved toward the central rim of the connection It.

Those portions of the loop 2 which pass over the pulleys 8 and 9 are manually insertable between and withdrawable from the spaces between the branches of the forked extremities of the bow. Hence, when the bow is not to be used for a considerable period of time the cord may be readily disengaged from one or both of the pulleys thus completely relaxing the elastic portion l5 and lengthening the period of its use.

It'should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the subject matter claimed.

What is claimed is:

1. In an archers bow, a bowed frame having forked extremities, pulleys provided with shafts journalled in and bridging the space between the 2 v I V L\ branches comprising the forks, and an arrow propelling loop extending around saidframe and over said pulleys, the portions of said loop which pass over said pulleys being manually insertable between and withdrawable from'the branches of said forks.

2. Inan archers bow, a bowed rigid frame provided with a grooved face extending lengthwise along its convex side, said bow having bifurcations in its ends, pulleys provided withshafts Journalled in andlocated between the branches of said bifurcations, and an arrow propelling connection occupy ns said grooved face and provided with elastics, said connection having looped end portions passing oversaid pulleys and joining each other at the concave side of the bow.

3. The subject matter of claim 2 and, an anchor included in said connection to which one end of each of said elastics are fastened, and

means to anchor said anchor in said frame.

4. In an archers bow, a flexible connection having a central run bridging the space between the end portions of the bow, said connection having elastic end runs at the convex side of the bow frame, means to anchor the extremities of said connection to said bow frame, and antifriction means over which said connection passes at the extremities of said bow. frame.

5. The subject matter of claim 4 and, said anchor means consisting of a rigid member secured to the mid-length portion of the bow frame, the end runs of said connection being secured to opposite end portions of said member.

6. The subject matter of claim 4 and, said elastic end runs of said connection consisting of tubes of elastic material.

7. In an archers bow, a flexible connection having a substantially inelastic central run which bridges the space between the extremities of the bow at the concave side thereof, anti-friction means for said-connection mountedupon each extremity of said bow, said inelastic centralrun of theconnection having end portions which pass over each of said anti-friction means .andare then directed along the opposite side of the bow. elastic runs forming extensions of said end portions of said inelastic run, and anchor means for said elastic runs secured to the mid-length portion of the bow.

, 8.-In an archers bow, a flexible bow string having a substantially inelastic central portion and having an elastic extension at each end. and means whereby the outer extremities of said elastic extensions are secured to said bow frames at the convex side thereof, said elastic extensions consisting of rubber tubes.

9. In an archers bow, a bowed rigid frame provided with a grooved face extending lengthwise along its convex side, 'said bow having bifurcations in its ends, pulleys provided with shafts journalled in and located between the branches of said bifurcations, an arrow propelling connection occupying said grooved face and provided with elastics, said connection having looped end portions passing over said pulleys and an anchor included in said connection to which one end of each of said elastics is fastened, means to anchor said anchor in said frame, ahand grip enclosing said anchor, and a guide-wayin said hand grip for positioning an arrow in said bow for propulsion.
