Bow ron' Application filed October as, 1927, Serial Myinvention relates to bowsand relates particularly'to bows for archery of the type permitting dissembling of the bow durlng periods of non-use into two parts for convenience in transporting the bow.

It'has been proposed to construct bows,

intended for various archery purposes, of

steel, and moreover it has been recently proposed to construct a bow comprising-a pair .of halves each similarly made'of solid steel, tapered toward their tips and ribbed on their rear sides in such a way as to accomplish the properties of distributed weight and resiliency desired to be had in bows to a very marked degree.

Heretofore also it has been proposed to provide a bow for archery having a pair of wooden limbs joined together in a handle so as to permit the limbs to be removable from the handle, whereby the space occupied by the bow in transportation is approximately decreased by one-half.

However, in order to prevent the halves from being displaced relative to the handle, it has previously been necessary, so far as I am aware, to secure the handle and bow halves together by pins or the like, which have various objections such as being inefiicient in the main purpose of joining the handle to the bow halves, coming loose after a number of operations and the like.

An object, therefore, of my present invention is to provide means particularly adapt-' able for bows having halves of non-circular solid sectional form, a securing means whereby 'the' handle or paradox supporting the handle may be removably secured to one or both halves of the bow.

Another object of my invention is to provide for the removably securing of a bow halve to a handle paradox without the necessity of employing pins or liek interlocking means which are susceptible to Wear and tear to which the bows are subjected in practice so as to effect depreciation of such flimsy securing means.

Another object of my invention is to pro- I vide a paradox for a bow having at least one of its metallic limbs adapted to be removably secured thereto merely by projecting the handle end of the limb into an end socket of the paradox with applied pressure and which will effectually hold such limb in place without the possibility of displacement during use.

Another object of myinvention is to provide a bow limb rece1v1ng paradox for an archers bow adapted to removably hold the 4 use without any relative rotation of the limb dox.

Another object of my invention is to provide an improved handle or paradox for an archers bow which will be most eflicient in use, which will stiffen the mid part of'the bow during use and securely hold the limbs of the bow in place and which may be produced in quantities in a relatively inexpensive manner.

Referring now to the drawings: Fig. 1 shows in elevation a bow embodying the principles of my invention.

ASSIGNOB TO THE AMERICAN FORK & H OE OHIO, A CORPORATION; OF 0310.

F1g. 2 is a longitudinal medial section through the paradox thereof shown en- Fig. 6 is a perspective view of a resilient liner extendin within the paradox throughout its lengt and defining the resilient sockets for the shank ends of the bow-limbs. Fig. 7 is a perspective view of the paradox supporting tube.

Fig. 8 is a rear elevational view of end fragments of one of the like bow-limbs, and

ignated by like reference characters, at 1 no aradox section 3 which joins the halvestogether.

The paradox 3 comprises a supporting tube 4, hand grip 5, preferabl of cork or like material with 6 and 7 soldered or ot erwise secured to the tube securing the cork hand grip in place, like end caps 8 telescoped over the two ends of the tube 4, the end caps being apertured as shown at 9, Figs. 4 and 10, for the reception of the shank portions such as 1 of the bow halves or l1mbs,.1 and 2. the paradox, I provide a socket tube 11 of approximately T-shaped cross-sectional form made preferably of steel with resilient walls, which extends from end to end within the tube 4 and is tightly wedged into position therein with its longitudinally extending curved wall 12 held tightly .in engagement with an inner wall of the tube by virtue-of the pressure inserted by a pair 0 wood strips 13 and 14 serving as fillers fitting in' the tube 4 between the medial rib 15 of the socket tube 11 and the opposing inside walls of the tube 4 and at the same time making compressive engagement with the inturned wall portions 16 of the socket tube so as to force the curved wall 12 thereof in 1 force than would benormally applied in the ti ht fitting engagement with the inner wal o the paradox tube.

The cross-sectional form of the sockets provided by the tube 11 such as that shown at 17 Fig. 6, conforms sufliciently closely to the cross-sectional form of the shanks 10 of the bow-halves so that a snug-fitting engagement may be had within the socket tube between its inner walls and the outer walls of the bow limb shanks.

As will be seen by reference to Figs. 8 and 9, although the bow limbs taper generally, as shown by Fig. 1, from the paradox en s of the limbs toward their tips 18 each supporting the cord 19, the shanks 10 of the bow limbs taper slightly toward their ends 20, which are chamfered as shown at 21, to facilitate easy introduction of the shanks into their sockets by the perforated openings 9 of the paradox caps.

It will be understood, of course, that these openings 9 will be in longitudinal allgmnent with the socket tube 11 so that a bow limb shank projected through one of the apertures 9 will be invariably directed thereby into one of the open ends 17 of the socket tube 11.

The edges 22 of the openings 9 are also chamfered toward their outermost portions as indicated best at 23, Fig.2, to facilitate introduction of the shanks 10 of the bow limbs.

The socket tube 11 may be made of a seamless tube of cylindrical form or it may be made with a seam which preferably, however, will be brazed either before or after the formation of the tube into the form of a flanged co ars .ally overcoming socket as illustrated in Fig. 6..v The seamed construction permits the tube 11 to be made from a strip of metal rather than from a tube, thus cutting down the cost of production. y I

It will be understood that when thetapered shanks 10 are forced into socket passage 17, that the outward pressure exerted b the inward telescoping movement 0 the s anks is yieldingly resisted by the resilient walls of the tube 11 and the wood fillers 13 and 14 which resist outward deformation of said walls and by tllf resiliency of the wood material, restore the walls to non-expanded form immediately when the bow limb is removed.

Although the bow limbs may be separately removable, I prefer to secure one of the bow limbs such as the bow limb 2 in place as illustrated in Fig. 2, so tightly that it will-re sist removal by pull much more than the f other bow limb. I may secure this result bow limb 2 with the socket or as by placby coating the shank of the adhesive before inserting it in in any other suitable way'such ing a wire in the socket so as eiiectve cross-sectional area prior to insertion of the shank which then must be pressed on by the application of considerably greater insertion of or removal of the other bow limb in its socket.

It will be understood that although I have illustrated and described both bow limbs as being removable from the paradox by manuthe effects of the frictional contact had between ner walls of their sockets receiving them, that I contemplate also the above described construction wherein one of the bow limbs is always retained-in its socket preferably by the use of an adhesive.

By referring also to Fig. 9, it will be seen that the shanks of the bow limbs are not quite straight but partake somewhat of the natural curvature of the bow limbs and effects a tighter wedging of the limbs in the metallic tubular socket 12 than would otherwise be the case since the socket passage does not normally partake of this curvature an resiliently resists being deformed, slightly, responsive to the rojection of the slightly curved shanks 10 into the sockets.

It will be seen that the lateral ribs 24 and the medial rib 25 of the bow-limbs project into corresponding sockets of the recess and that relative rotation of. the socket and bow limbs is thereby effectually prevented. The caps 8 soldered or otherwise rigidly secured to the ends of the paradox tube 4 when the bow limbs are in place projecting through the perforations 9 of the caps, effectually prevent any relatitve rotation of the bow limbs and socket tube 11 relative to the paradox tube 4.

the shanks and the into decrease its By reference particularly to Figs. 2 and 3, it will be seen that the ends of the bow limbs approach but preferably do not contact with each other, a space 26 being preferably left between the ends of the bow limb shanks when these have been forced inwardly as far as is possible. The curvature of the bow limbs and the degree of taper given them in their shank portions, operate to practically prevent further projection of the shanks into the sockets.

Having thus described my invention in a specific embodiment, I am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described but without departing from the spirit of my invention.
