Application June '29, 1954, Serial No. 440,115

Claims. (Cl. 124-43) This invention relates to a new and improved kind of bow of the type that is used in archery. In particular the invention is directed to the means for securing the string to the ends of the bow.

An object of this invention is to provide a securing means which can utilize a string that does not need to have spliced bights or knots or the like at its ends and which, consequently, allows for adjustment of the string to divide the wear over different portions of its length and allows for easy adjustability of the tension.

Another object of this invention is to provide a means for securing the string to the ends of the bow which is simpler and cheaper to make than the customary notch system and which can, if desired, be used on a straight rather than an arched bow.

A further object of this invention is to provide a means for securing a string to the ends of a bow which better allows for the use of the bow arched either convexly or concavely and by either right or left-handed persons. This allows for greater tension and lengthens the life of the bow. The securing means also is of such nature that it serves to strengthen the tips of the bow.

Other and further objects of the invention will be apparent upon reading of the below description, and the appended drawings. These drawings are:

Fig. 1 is a plan view of the assembled bow showing the invention.

Fig. 2 is a partial perspective view of one end of the bow showing the invention in use.

Fig. 3 is the same as Fig. 2 except showing the other end of the bow.

Fig. 4 is a perspective view of the same end of the bow as Fig. 2 showing another view of the bow.

Fig. 5 is a perspective view showing the method of securing the string to one end of the bow.

In general in this invention the string is secured to each end of the bow by passing each end through a hole near the ends of the bow and lashing it about the shaft. The bow may then be arched and the string passed over the two end portions thus providing tension in the bow and the string.

Fig. 1 shows the assembled bow with the string under tension. In this figure, the shaft of the bow is generally represented by the numeral 1 and is preferably made of resilient material such as wood or thin steel. The shaft 1 may be either arched or straight. In the middle of the shaft 1 there is ordinarily placed a gripping portion or handle 2. The string 7 is shown under tension, secured at each end of the how 1 and passing between its two ends. As shown in Figs. 2, 3, 4 and 5, generally concave guiding portions 3 and 4 are provided one at each end of the shaft of bow 1. Guiding portion 3 is at end 5 and guiding portion 4 is at end 6. Located adjacent to the portions 3 and 4 are

string guiding holes

8 and 9 passing through

ends

5 and 6, respectively, of the shaft 1. These holes are best placed about one and one-half inches from portions 3 and 4. Preferably, the axes of portions 3 and 4 and of

holes

8 and 9 lie in the same plane. The

pp 2,758,587 Patented Aug. 14, 1956 2 depth of portions 3 and 4 may be varied in accordance with the preferences of the user; and in some instances it may be desirable to in effect leave no depth.

In Figures 2 and 4 the string 7 is shown to pass through guide 3. The portion 11 of the string 7 which has passed through the guide has been led through hole 8 and then secured about the end 5. This securing is preferably done by winding string portion 11 about the end 5 for about three turns. This lashing should be preferably about the portion" 5 of shaft 1 between guiding portion 3 and hole 8. The tip 15 of string 7 may, if desired, pass beneath one'of the lashings to be additionally secured as shown in Fig. 2. If, as illustrated in Fig. 4, the lashings 13 are between string portion 11 and end 5 of the shaft the tension on string 11 will further serve to secure the string in position.

Figs. 3 and 5 show the comparable structure for the other end of the bow. In these figures the string 7 has an end portion 12 which passes through portion 4 on end 6 of shaft 1 and thence through hole 9. It is wound above the shaft end 6 in several lashings 14; and the end of string portion 12 may be secured beneath one of the lashings 14 as shown. I

To use the stringing system of this invention, one end of the bow is first secured to the string in the manner described. Thus, Fig. 5 would illustrate the situation where the string 12 has been passed through hole 9, and lashings 14 are about the shaft portion 6, but where string portion 12 has not yet been passed through guiding portion 4. Next, it is best passed through hole 8 and lashed about the bow as at 13. In this manner the string length can be easily adjusted so that the proper tension may be had. Once the string 11 has passed through

string retaining holes

8 and 9 and has been lashed about the

ends

5 and 6 of the shaft, the bow is arched in the usual manner and string 7 slipped into guide portions 3 and 4. Release of the tension on the bow caused by the arching will result in the bows tending to straighten, thus placing the desired amount of tension on the string.

It can be seen that through use of this invention the bow may be arched in opposite directions simply by passing the string through the

holes

8 and 9 and the portions 3 and 4 in the opposite direction. It also can be seen that tension on the string 7 can be easily adjusted by varying the portion of the

string

11 or 12 which passes through the

holes

8 or 9 so that the normal length of the string between the grooves 3 and 4 is varied. Likewise, wear need not always be on the same portions of the string because the portions of the string passing through the portions 3 and 4 and

holes

8 and 9 may be changed simply by moving thestring a fraction of an inch in either direction throughout the entire securing means. As is desired, the string may also be moved from the center of the end portions toward either side.

It also will be seen that the fact that there are lashings about each end of the bow will serve to strengthen the ends at the very points that weakness often occurs.

Various modifications of this invention may of course be made without departing from its spirit.

I claim:

1. A bow of the character described in which an unknotted and unspliced string may be used and which allows for adjustment of the string tension, said bow including a resilient shaft, said shaft having concave guiding portions formed at each end thereof and two string-retaining holes, one proximate to each of said guiding portions, the axis of said guiding portions and of said holes lying in the same plane, a string of greater length than said shaft, said string being secured at each end of said shaft by passing first through one of said guiding portions, then through its proximate hole and then being lashed about said shaft between said guiding portion and said hole and between said string and said shaft, said holes and their respectivetsaid guiding portions being so positioned relative to fine another that the tension upon said string when said bow is set' will tend to secure said lashing in place. I I V 2.
