PAUL E. KVISTAD, OF SPOKANE, WASHINGTON.

ARCHER/S BOW.

Application filed July 25, 1918.

To all whom it may concern Be it known that I, PAUL E. Kvrs'riu), a citizen of the United States, residing at Spokane, in the county of Spokane and State of lVashington, have invented certain new and useful Improvements in r1rchers Bows, of which the following is a specification.

My invention relates to improvements in archers bows especially adapted for target and practice shooting, and has for its object the provision of a bow possessing unusual power combined with ease and convenience of operation, and embodying certain novel and meritorious features of construction.

Broadly, my invention consists of a mechanical leverage means for bending the bow, supporting and guiding means for the arrows or projectiles, and a retaining and releasing means for the bow string.

Minor features and the details of construction will be hereinafter pointed out in connection with the accompanying drawings forming a part of my application, and in which:

Figure 1 is a vertical front plan view of the bow. Fig. 2 is a side View in elevation showing the bow before and after bending, the latter aspect being indicated in dash lines. Fig. 3 is a side plan view of the bow bending lever and arrow guide and magazine. Fig. 1 is a top plan view thereof. Fig. 5 is a top sectional view, somewhat enlarged, of the magazine, string retaining and releasing device which are mounted upon the bow bending lever. Fig. 6 is a detail view showing the pivoted end of the said lever and arrow guide. Fig. 7 is an enlarged view of the details of the magazine arrow serving contrivance. Fig. 8 is a view of another detail of the latter. Fig. 9 is a View showing my preferred form of arrow which is especially designed for the bow, and Fig. 10 is a rear end view thereof.

Referring more specifically to the drawings in which like reference characters are used to indicate like parts in the several views, the numeral 1 designates a lower or bottom leg of the bow of solid construction and 2 a split or double upper leg composed of the two sections 3 all being permanently bound together by means of the rings or bands 4. For retaining the sections 3 of the split or double upper leg in fixed spaced relation there is provided near their outer ends the rivet 5 to which is attached one end of Specification of Letters Patent.

the bow-string 6. At the lowermost end of the said lower leg 1 is secured a foot-rest 7 and the other end of the bow-string.

My construction contemplates a bow five or six feet in length and tension elements of great resistance capable of projecting the arrow or projectile at high speed for a considerable distance. I have therefore found it necessary to provide the said foot-rest and a leverage means for bending the bow in order that those of moderate strength can operate the same without excessive physical exertion.

The bow bending lever 7 which is split for nearly its entire length is composed of the two side-bar guide sections 8 which, besides serving to bend the bow, also form a guide or directing means for the arrows which it is adapted to receive for firing. This lever 7 is pivotally mounted on and between the two sections 3 of the double upper leg 2 at the middle point of the bow by means of the pins 9. The opposite end of the lever member terminates in a handle or grip 10. The pulley-wheels 11 are mounted between the side-bar sections 8 by means of the pins 12, as shown in Fig. 5, and serve to retain the bow-string during the bending operation and until released to project the arrow. The upper faces of the side-bar section 8 of the lever 7 are slightly chamfered so as to provide a guideway or groove 13 along which the arrows are projected when the bowstring is released. In Fig. 5 is shown an arrow in place within the said guideway ready for shooting.

In order to bend the bow by means of the lever the latter is positioned as shown in Fig. 2 (solid lines), and by grasping the handle portion 10 the lever may he swung and forced into the position shown in dash-lines in said figure and the bending of the bow and setting of the bow-string accomplished. By pressure of the thumb within the wedgeshaped recess 14 at the rear end of the lever the side-bar sections 8 may be forced slightly farther apart to allow the bow string to pass between and along the guideway 13 to engage the rear face of the arrow 25 and project it through the opening between the sections 3 of the double upper leg 2 of the bow and thence to the target.

Mounted on the lever on each side of the arrow guideway is a chamber 15 of the magazine 16 for receiving extra arrows. The arrows are inserted in the chamber from the rear through the opening 17 and through loop 18 of the spring 19 shown in Fig. 8, the engaging portion 20 of the said spring serving to engage the arrows for the purpose hereinafter described. Pivotally mounted on each side of the said lever 7 at the point 21 is the device shown in Fig. 7 which has an extension 22 by which the device is manipulated, and also the upstanding web portion 23. This web portion serves to retain and prevent the arrows from being shunted sidewise by the said spring 19, Fig. 8, until such time as it is desired to bring one of them in the path of the bow-string within the guideway 18. When it is so de sired pressure of the thumb or finger upon one of the extensions 22 will cause the web 23 to be lowered so that the spring 19 acting upon the arrow will force it into the central firing position shown in Fig. 5. After the operation the web will return to its normal closed position to support another arrow by the action of the spring 24: when pressure on the extension is removed.

In the use of the foregoing device the arrow is to be placed in shooting position after the bow has been bent. The arrow 25 which I have shown in the drawings is best adapted for my contrivance, and is preferably constructed of metal and provided with vanes or feathers 26 to guide it properly. To receive and retain the latter the butt of the arrow'is slotted four ways as shown and provided with a central aperture 27. The feathers are then placed in position with the quills thereof within the said aperture, the vanes extending through the two nearest slots. A wooden plug 28 is then inserted to maintain the feathers in position and the end of the plug made to extend slightly beyond the end of the arrow proper to be engaged by the bow-string.

From the foregoing description it is apparent that I have provided a very powerful bow which is easily manipulated and well adapted for vthe purpose intended.

While I have described an operative device l showing a specific structure and specific parts, it is to be understood that I reserve the right to make any changes in the form or arrangement of the parts as long as such changes do not depart from the spirit of my invention as set forth in the annexed claims.

Having described my improvements, I claim as new and desire to secure by Letters Patent of the United States 1. A11 archers bow comprising a split tension member, a bow-string and a split lever pivotally mounted thereon for bending the tension member, and means for retaining and releasing the bow-string.

2. An archers bow comprising a split tension member, a bow-string and a split lever pivotally mounted thereon for bending the tension member, and retaining and releasing means for the bow-string consisting of separate contacting elements carried by the said split lever.

3. An archers bow comprising a split tension member, a bow-string and a split lever pivotally mounted thereon for bending the tension member, and a retaining and releasing means for the bow-string consisting of two oppositely disposed contacting members carried by the split lever and means for disengaging said contacting members.

4. An archers bow comprising a split tension member, a bow string and grooved split lever pivotally mounted thereon for bending the tension member, a' bow-string retaining and releasing means, and a projectile magazine and serving contrivance carried by the said split lever, consisting of a spring retainer and a pivoted releasing member cooperating therewith.

5. In an archers bow, the combination with a tension member, a bow-string, and a lever for bending the bow, of a projectile re- L taining and serving contrivance mounted upon the said lever.

In testimony whereof I aflix my signature.
