Bow.
Application iilea ma '7, 11928. Serial No. 275,782. has all the advantages of a bow of one solid piece. As a rule bows for use in archery are about as tall as the archer who uses them and it is quite inconvenient to carry such a bow in an ordinary closed automobile, on a crowded streetcar, or omnibus, and it is even inconvenient to carry them on the open street. For almost 100 years various kinds of jointed bows have been attempted, but none of these have ever found universal favor because they were not as satisfactory as the bows of one single piece and archers prefer the inconvenience caused by the long bow, rather than to use jointed bows of inferior quality.
Furthermore, the bows at present used in archery are quite long and cannot be stored conveniently in a trunk, and cannot be easily transported from place to place, and by making the bow in two separate parts, which may be assembled together when desired, the bow can be more easily carried as baggage, or transported. Since the rear and front of the bow are of different contours, in order to secure the proper assembly of the two parts, it will be necessary to provide a joint, in which the two parts will always fit together in the same relative position one to the other. In making a jointed'bow, the following things must be considered and are of importance in the order mentioned.
'1. Alignment-The back of the bow (the side away from the bow string) is usually different in contour than the belly, (the side next to the bowstring),'although this is not always the case. Consequently, a bow that is jointed in the handle should have some arrangement that will secure the proper alignment of the two limbs when they are put together. Heretofore those using jointed each other bows have usually depended upon the eye for this adjustment, and had no means for holding the bow in positive alignment. My invention entirely offsets this difficulty, and the mere bringing together of the two limbs of the bow, inserting the ferrule properly, insures absolute alignment of the limbs.
2, Compensation for wear - In all of the previously jointed bows there has been no arrangement for the take-up of Wear. This is of vast importance as the joint has worn and become shaky, which creaks or gives when the bow is drawn, or which for any reason does not have the firm rigidity of a solid piece, tends to disconcert the archer while shooting, with a consequent disastrous result. The construction of the upon his score tapered joint in my invention is such that wear is automatically compensated for and even in case, there is very considerable space between the male and female ferrule, any looseness is immediately compensated for once the bow has been strung, because of the wedging action of the ends of the bow against
3. Anti-freeze "feature. One great difficulty of all previous jointed bows has been that if a close, tight fit is made, such as would be required to keep the ordinary jointed bow rigid, there is great danger of this joint freezing or sticking so that it cannot be pulled apart. This also frequently caused foreign matter getting in the joint and preventing the ready separation of the two limbs. The peculiar fact about such a frozen joint is that the ferrules can frequently be turned within each other, yet will resist withdrawal. The construction of my invention is such that even a slight turn of these ferrules will tend to force them apart. No other jointed bow has ever had this advantage and the lack of it has prevented many archers from using the convenient jointed bow.
Strength will be just as satisfactory as a one piece bow, a jointed bow must have equal strength at the joint,(or handle) as that of the one piece weapon; The construction of my invention is such that the joint is the strongest part of the bow This is particularly true because the diagonal feature of the taken apart, are of approximately the length. In many jointed bows, one limb is considerably longer than the other when taken apart and in consequence, the bow, when taken down is considerably longer than half the length of the full bow. In many designs of jointed bows this difference is as much as eight or ten inches, very nearly off setting the advantages of the take-apart feature.
The foregoing objects are accomplished by my invention, which will be more clearly understood after reference to the accompanying drawings, in which like parts are indicated by similar reference symbols throughout the several views,and in which, Figure 1 is a diagram, showing an archer, in dotted lines, holding a bow.
Figure Q shows a side elevation of the two arm bow without the string.
Figure 3 is an elevation of the curved side of the bow away from the archer, the bow string being omitted.
Figure 4 shows the two members of the bows separated.
Figure 5 is a sectional elevation on a larqer scale, showing one form of joint used assembling the two arms of the bow.
Figure 6 shows a section along the line 66 of Figure 5, and'looking down.
Figure 7 shows a section along the line 77 of Figure 5, and looking down.
Figure 8 shows a section along the line 8-8 of Figure 5, and looking down, and Figure 9 is a similar view to Figure 5, but shows a modified form of joint.
The bow A consists of two limbs connected together, so that the belly a of each limb will be next to the archer and the back will be furthest away from the archer. The end of each limb might be provided with a suitable tip B which may be in the form of a ferrule notched as at 7) to engage a bowstring C, shown only in Figure 1.
in order to form a strong and firm joint, one of the limbs, as A is provided with a metal, cylindrical sleeve D firmly secured thereon, and, the other limb A is provided with a similar sleeve D, which fits snugly in the sleeve D, but has "its outer end cut away at an ***, as indicated at cl and (Z to form a plane surface with the beveled face a? of the limb A", see Figure 5. The other limb A is provided with a similar beveled face a so that when the parts are assembled in the position shown in Figure 5, there will be a firm joint made, and each limb of the bow cannot twist in its socket, but the desired alignment of the two limbs will be effected.
Thus when the parts are assembled, as shown in Figure 5, the bow will be ready for use, and yet the two limbs may be readily taken apart, as shown in Figure i.
While the sleeves D and D may be heated and shrunken the ends of the corresponding limbs of the bow, obviously they might be further held in place by one or more pins, such as E, shown in Figures 5, 7 and 9.
In Figure'9, I have shown a slightly different form of joint, in that, instead of having the ends of the limbs A and A beveled, as shown in Figure 5, there is a wedge, or tongue and groove engagement in which one limb A is provided with the wedge a which fits into a corresponding tapered groove i in the opposite limb A. In this case, the inner sleeve D would be in the form of a hollow cylinder with V-shaped cuts therein, and not cut away diagonally, as shown. in Figure '5.
It will be seen that in either form of joint, when the two limbs of the bow are assembled in the socket piece, the limbs will be in alignment throughout, and will'not require any line adjustment or twisting of the two limbs, so as to get them in the proper alignment.
By having the abutting faces of the two limbs of the bow in beveled engagement, as shown, the effect of the taut string, will tend to pull the two members together and thus automatically hold the two limbs in the proper adjustment, but will also automatically adjust the bow for wear at the abutting faces.
It will be obvious that the two limbs of the bow may be separated, and put in a bag, or otherwise conveniently carried, and may be quickly assembled and the "bow string applied whenever it is desired to use the bow.
While I have shown two preferred embodiments of the invention, it will be obvious that various changes might be made in the construction, combination and arrangement of parts, which could be used without departing from the spirit of my invention, and I do not mean to limit the invention to such details, except as particularly pointed out in the claims.
Having thus described my invention, two limbs of the bow, and whereby the two sleeves secured on the inner end of one limb so limbs are held against angular movement and projecting therefrom, and a similar; relative to each other. sleeve fitting snugly over the adjacent end of 2. A bow comprising two limbs, each limb the abutting limb, and adapted to fit snugly tapering towards the outer end thereof, the in the first mentioned sleeve, whereby a firm inner and thicker end of each limb being is secured for the two limbs of the bow, provided with a plane, diagonally disposed abut and whereby the two limbs are held against its face adapted to bear against the angular movement relative to each other.
