Abstract

An arrow attachment for inducing hemorrhaging in a big game target has at least one cutting blade movable from a retracted, inoperative position to a projected operative cutting position, the blade being provided with an actuating member which projects outwardly relative to the blade and which, upon being subjected to an impact resistance, functions to move the cutting blade from the retracted position toward the projected position.

Claims

1. An arrow attachment comprising a body having an elongate slot extending therethrough;

a pair of blades accommodated in said slot in side-by-side relation;

each of said blades having a cutting edge;

pivot means mounting said blades on said body for rocking movements about an axis between a retracted position within said slot and a projected position in which each of said blades extends laterally outwardly of said slot and on opposite sides of said body; and

actuating means carried by each of said blades and extending outwardly of said slot when its associated blade is in said retracted position, each of said actuating means being so located relative to its associated blade as to be operable to rock its associated blade from said retracted position toward said projected position in response to the application of force on such actuating means in one direction, the extent of the rocking movement being such that each of said actuating means may move from a projected position at one side of said body through said slot to a projected position at the opposite side of said body.

2. The arrow attachment of claim 1 wherein said pivot means for each of said blades is between opposite ends thereof.

3. The arrow attachment of claim 1 wherein each of said actuating means is integral with its associated blade.

4. The arrow attachment of claim 1 wherein said actuating means lie alongside and substantially parallel to said blades when said blades are in their projected positions.

5. The arrow attachment of claim 1 wherein a single pivot means mounts said blades in overlying parallel relation in their retracted position.

6. The arrow attachment of claim 1 wherein each of said actuating means is curvilinear and terminates in a hooked end portion facing said one direction when its associated blade is in said retracted position.

7. An arrow attachment for inducing hemorrhaging comprising a body;

a pair of cutting blades;

a slot in said body accommodating said cutting blades in a retracted position thereof;

pivot means mounting said blades in said slot for movement relative to said body from said retracted position to a projected position;

actuating means carried by said blades and extending outwardly of said body when said blades are in said retracted position, said actuating means being integrally formed with said blades and operable to move said blades to their projected position in response to the application of force in one direction on said actuating means, each of said blade actuating means being substantially parallel to the other of said blades when said blades are in the projected position;

stop means for limiting movement of said integral blades and the blade actuating means relative to said body; and

spring means carried by said body for engagement with said cutting blades for releasably holding the latter in said retracted position.
