June 20, 1961 R. A. LAMOND ARROW BRAKE AND INDICATOR DEVICES Filed Sept. 25, 1959 IN VEN TOR.

2055,97- ,4, ZAMO/VO United States Patent 2 989,310 ARROW BRAKE INDICATOR DEVIFES Robert A. Lamond, 745 Durant St, Lansing, Mich. Filed Sept. 25, 1959, Ser. No. 842,356 7 Claims. (Cl. 273-1065) This invention relates to combined brake and indicator devices for arrows.

The primary object of the invention is to provide devices of the kind indicated which, when installed on arrows, serve to arrest complete penetration of the arrows through the body of game shot with the arrows, so that the arrows are caused to remain lethally in the body and thereby give clearly visible evidence of penetration of a body and of the whereabouts of the arrows, which would otherwise pass completely through the body and become diflicult to find, as in thick brush.

Another object of the invention is to provide simple and efficient devices of the character indicated above, which attachments are readily applied to and removed from arrows, and which do not perceptibly alter the flight trajectories or accuracy of arrows.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is a contracted side elevation of an arrow equipped with a device of the invention, the device being shown in full lines in its initial position at the head or point of the arrow, and in an intermediate, and in a final indicating position, in phantom lines;

FIGURE 2 is a fragmentary elevation, taken at right angles to FIGURE 1, of the head or point of the arrow, showing the device in its initial or starting position thereat;

FIGURE 3 is a fragmentary elevation taken at right angles to FIGURE 1, of the feather-equipped end of the arrow, showing the device compressing the feathers so as to halt passage of the arrow through a body;

FIGURE 4 is a transverse section taken on the line 4-4 of FIGURE 3;

FIGURE Sis a perspective view of another device of the invention; and v FIGURE 6 is an enlarged longitudinal section taken on the line 6-6 of FIGURE 5.

Referring in, detail to the drawings, wherein like and related numerals designate like and related parts throughout the several views, and first to FIGURES l to 4, the numeral 10 generally designates a substantially conventional bow-show game-hunting arrow, having a shaft 12 having a sharpened triangular head or point 14 secured on its forward end, and guide vanes on its rear end, here shown as being three circumferentially spaced, normally resilient feathers 16. Installed on the arrow shaft 12 is a device of the invention, generally designated 18.

The device 18, which can be made of lightweight metal, plastic or other suitable material, comprises a longitudinally elongated sleeve 20, whose bore 22 is not substantially larger in diameter than the arrow shaft on which the device is to be installed. To be adaptable to arrow shafts of different diameters, the sleeve 20 can be made resilient and be longitudinally split, as indicated at 24, in which case, suitable sleeve-contracting means is used on the sleeve, such as a wrapping of adhesive tape 26, which is drawn tight enough only to contract the sleeve diametrically to be freely slidable along the arrow shaft 12. In aid of unobstructed rearward sliding of the sleeve 20 along the arrow shaft, the sleeve is chamfered, bevelled, or rounded internally at its rear end, as indicated at 28.

Fixed on the sleeve 20 and extending forwardly therefrom, at an acute outward angle relative to the longitudinal axis of the sleeve 20 and the arrow shaft 12, is a thin, rigid spike 30. With the device 18 installed on the arrow shaft 12 in its initial or starting position, wherein the sleeve 20 is directly behind and preferably abuts the rear end of the head or point 14, the spike 30 is long enough to reach forwardly alongside of the head or point, to a point spaced rearwardly from the forward end 32 of the head or point 14, as seen in FIGURES l and 2. The spike 30 is preferably tapered forwardly to a sharp point or tip 34, and of uniform cross-section, such as round or square. Securement of the spike 30 to the sleeve 20 can be effected in different ways, as by fixation thereof to the outer side of the sleeve, as indicated at 36, which arrangement would be especially appropriate andfeasible in the case of the device 18 being formed of molded plastic.

With the device 18 in the above described initial or starting position, and the arrow being shot from a bow at power sufficient to produce complete penetration of the arrow into the body of game aimed at, the head 14 and shaft 12 of the arrow penetrate the body in the usual way and the spike 30 of the device 18 becomes impaled in the body and moves rearwardly along the arrow shaft 12, and in so doing, because of the outward canting of the spike 30 relative to the sleeve 20, the spike 30 diverges further away from the arrow shaft 12, so as to tilt the spike 30 on the arrow shaft and move the sleeve rearwardly along the arrow shaft, as the device 18 reaches the feathers and starts to move rearwardly over the feathers 16. Because the feathers 16 are rearwardly flared, the further rearwardly the device 18 is thus moved, the more feathers are compressed within the sleeve 20, until the sleeve 20 becomes wedged on the feathers .and is arrested by the resulted braking action, and the device becomes jammed in the body and stops the arrow from passing through the body.

Further, in the event of a complete miss of a target, and passage of the arrow 10 through brush, grass, or trees, the spike 30 of the device 18 will pick up, and jam between itself and the arrow shaft 12 and the sleeve 20, sutficient vegetation: to render the arrow more readily visible, for recovery, than otherwise. Further, the tearing and/or pulling action of the spike 30 as it may pass through bushes and'the like, can leave a readily visible trail therethrough as a guide to recovery of the arrow 10, and, in the case of complete penetration through an ani' mal, leave a visible trail of blood.

For holding the device 18 releasably in its initial or starting position, at the head of the arrow 10, with sufficient tenacity to preclude vagrant rearwardly displacement of the device 18, retaining means, such as a short length of adhesive tape 38 can be adhered to the sleeve 20, at its forward end 40, and to the arrow shaft 12 forwardly of the device, as shown in FIGURES 1 and 2.

The form of the invention shown in FIGURES 5 and 6, and generally designated 18a, comprise a split sleeve 20a, generally similar to that of the device of FIGURES l to 4, which is internally rounded, as indicated at 28a, at its rear end, and a spike 30a. The spike 30a differs from that of FIGURES 1 to 4 in being of flat rectangular cross-section whose main plane is radial to the sleeve 20a. Replacing the retaining tape 38 of the device of FIGURES 65 l to 4, is a leaf spring 38a which is fixed to the sleeve 30:: between the split 24a and the spike 30a and extends forwardly beyond the forward end 40:: of the sleeve, and tensioned inwardly to bias against an arrow shaft.

While there has been shown and described herein a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.
