Application September 6, 1955, Serial No. 532,697.

4 Claims. (Cl. 124-24) This invention relates to archery bows for propelling arrows and more particularly to a bow having a center portion or handle especially shaped to fit the hand of the user.

It is among the objects of the invention to provide an archery how the center portion or handle of which is so shaped that a portion thereof of a length substantially equal to the width of a hand is inclined downwardly and rearwardly or toward the bow string so that the fingers of the hand grasping the bow will fit comfortably and firmly around this portion with the wrist straight and the bow in an upright, substantially vertical position; which provides a rounded projection which fits comfortably into the palm of the hand holding the bow to provide a firm grip on the handle and a means for more accurately aligning the bow with the target; which relieves the bow of the tilting pressures which occur when a bow with a straight handle is held in shooting position and an arrow is drawn against the bow string so that a bow provided with the shaped handle of the present invention may have both upper and lower limbs of the same length and stiffness rather than makingthe lower limb shorter and stiffer than the upper limb as is done with straight handled bows; which enables the crotch of the thumb and forefinger of the hand holding the bow to fulcrum the how so that the forces above and below the fulcrum point are equal and thus provides for the natural aiming ,or pointing of the arrow toward the target without the necessity for any compensation for tilting movement of the bow at the time the arrow is released; and which provides a handle of adequate strength and rigidity as well as one that is especially neat and attractive in appearance.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing in which:

Fig. 1 is a side elevational view of a bow having a center portion or handle constructed in accordance with the invention;

Fig. 2 is a perspective view of the center or handle portion of the bow;

Fig. 3 is a front elevational view of the center or handle portion of the bow; and

Fig. 4 is a rear elevational view of the center or handle portion of the bow.

With continued reference to the drawing, the numeral designates the center or handle portion of the bow, the numeral 11 the lower limb, the numeral 12 the upper limb and the numeral 14 the bow string. The upper and lower limbs 11 and 12 may be of conventional shape and construction except that both are preferably of the same length and stiffness, and the bow string 14 is of any usual .side proximate to thebow string.

2,842,113 Patented July 8, 1958 The handle section 10 includes three portions: an upper end portion, a lower end portion, and a grip portion 18 extending between and interconnecting the mutually adjacent ends of the upper and lower end portions. The upper and lower limbs 12 and 11 are joined to the upper and lower portions of the handle section and extend longitudinally from the mutually remote ends of the corresponding upper and lower portions of the handle section.

Archery bows of the character generally described above and in which the grip portion is substantially in line with the end portions of the handle section are old and well known.

in using a how, the bow supporting arm is extended outwardly, substantially rigidly from the body and the bow supporting hand firmly grasps the grip portion with the bow string between this hand and the body. In order to hold the bow so that the bow string is substantially vertical the wrist of the bow supporting hand has to be bent upwardly so that the third and fourth fingers of this hand can extend around the grip portion. The arrow is then fitted to the bow string and drawn and the force required to draw the arrow puts an upward bending tension on the already upwardly bent wrist of the bow supporting hand and on the entire bow supporting arm. When the arrow is released this tension is suddenly relieved and the bow supporting hand tends to snap downwardly, inclining the bow downwardly and rearwardly and even moving the bow bodily downward before the arrow is entirely clear of the how. This tends to spoil the aim of the arrow and, even though experts in archery learn to compensate this tendency to a satisfactory extent with light target hows, it has been found impossible to compensate when using a heavy how, such as a stiff hunting how.

Some attempts have been made to improve bow handle sections to overcome this tendency to snap the bow downwardly or to otherwise twist or shake the how when the arrow is released but these previous attempts have been far from successful. The greatest previous modification has been to provide a rounded notch or recess in the rear or inner side of the bow at the upper end of the grip portion to provide a shoulder to rest on the hand at the crotch of the thumb and forefinger. Such a construction is shown in the patent to Meyer, No. 2,689,559, patented September 21, 1954. Such a construction does not, however overcome the necessity for radically bending the wrist in order to hold the bow string in upright position since the third and fourth fingers of the bow supporting hand must still extend around the unrelieved back or outer side of the bow handle in order to hold the bow steady.

It is conceived that, in order to hold the bow with the bow string substantially vertical and without bending of or undue strain upon the bow supporting arm and wrist, the grip portion of the handle section of the bow is so inclined that its prolonged longitudinal center line intercepts the taut but straight bow string at an angle which is substantially equal to the angle between the center line of the forearm and a line substantially touching all of the first joint finger knuckles of the bow supporting hand when the fingers are bent to form a fist and the wrist is held straight. It is contemplated, however, that since a limited amount of compensation on the part of the archer is possible, this range can be increased or reduced. It is therefore considered that a range of inclination of the prolonged longitudinal center line of the grip portion to the straight bow string of from 20 to 60 degrees of angularity is within the scope of the present invention.

Various methods of manufacturing the integral center or handle section with the inclined grip portion may be employed. As shown, the handle section is recessed t0 provide notches 15 and 16 at the back and face sides of the grip portion 18. These notches 15 and 16 are of generally triangular shape and oppositely directed, leaving between them the inclined grip portion 18 of substantially uniform thickness. If desired, one end of the handle section may be offset from the adjacent end of the grip portion, as indicated at 17 in Fig. 1 wherein the lower end of the handle section is offset forwardly from the lower end of the grip portion 18.

The recesses 15 and 16 are so shaped and arranged that, when the strung bow is held in proper upright position with the bow string straight and substantially vertical, the grip portion 18 is inclined from its upper end downwardly and toward the bow string and the upper end of the recess 16 provides a shoulder 20 projecting from the face side of the upper end of the grip portion 1% toward the bow string. This shoulder and the adjacent portion of the grip is formed to provide a rounded notch which comfortably receives the web at the juncture of the thumb and forefinger of the bow supporting hand and provides a fulcrum for bending the bow.

The recesses 15 and 16 are so dimensioned that the grip 18 has a length somewhat greater than the width of the palm of the bow supporting hand for which the grip is designed, and the notch 15 provides a deep discontinuity in the curvature of the back side of the how so that the back side of the grip portion is inclined to this curvature. It will be understood in this connection that bows of the character contemplated here are not only made in different sizes and with dilferent draw pulls but are often semicustom made and fitted to the physical characteristics of the individual archer. They are also provided in right hand and left hand forms as may be required.

While a construction method has been suggested it is to be understood that the handle section may be produced by other methods as long as the integral nature of the entire section and the proper forward and rearward inclination of the grip portion is maintained.

The lower end of the grip portion 18 may be extended rearwardly or toward the bow string and rounded olf to provide a smooth formation where the lower end of the grip portion joins the lower end of the handle section and the upper end of the grip portion may, except for the shoulder 20, be smoothly faired into the lower end of the upper end portion of the handle section. The entire shape of the handle section, except for inclination, length and substantially uniform thickness of the grip portion may be extensively modified, if desired, for ornamental or other purposes.

For example the notch 15 may be provided as a partly or wholly inclosed finger opening and the shoulders 21) or 21, or both of them, may be shaped with reverse curves.

A transverse arrow groove 24 is provided in one side of the handle at or just above the level of the shoulder 20 which will place the arrow at the top of the forefinger of the-hand holding the bow so that the arrow will be aimed in the natural manner. The improved handle also tends to hold the bow straight with the straightened wrist and arm when the arrow is drawn so that there is no tendency for the center line of the arrow to pull out of the plane of the center line of the how.

The center portion of the bow is preferably of laminated construction for maximum strength and shaped to fair at its ends gradually into the upper and lower limbs of the bow and the grip portion of the center portion or handle of the bow may be custom carved to fit the hand of the individual bowman and satisfy any detailed requirements of design or ornamentation, or the handles may be shaped to an average construction for quantity production. It is also within the scope of the invention to form the handle portion of the bow separately and of dilferent materials, such as wood, metal or plastic.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
