Abstract
Abstract An arrowhead fabricated from two separate blades arranged at cross angles to one another and held in position by a collet, the collet having a cooperating cam sleeve for detachably locking the blades together in a rigid manner. A threaded insert is provided for the collet by means of which the latter can be removed from and attached to the arrow shaft and provides for withdrawing the arrowhead assembly from the game and for disassembly of the arrowhead for sharpening or repair purposes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
235 words
A removable arrowhead assembly comprising at least one blade having a recess extending inwardly from the rear edge thereof, a collet having at least one axial slot for the reception of said blade therein, said collet also having a cam surface and a threaded rearward end, a sleeve accommodated by said recess in said blade and having a cam surface adapted to abut against said cam surface of said collet for causing said collet to clamp tightly against said blade, said sleeve having at least one axial slot on the exterior thereof in axial alignment with said one axial slot in said collet, said slot in said sleeve receiving said blade for rigidly holding the latter in relationship to said sleeve, means located on the inner surface of said sleeve and interengaging with means on the exterior surface of said collet for preventing relative rotation between said collet and said sleeve, an insert having an internal thread for the reception of the threaded end of said collet, said insert being adapted to be secured to an arrow shaft, a metal impact ring mounted around said collet, said blade bearing against said metal impact ring when in assembled relationship, whereby said collet can be inserted in said sleeve and threadably engaged in said insert to tightly draw said collet cam surface against said sleeve cam surface for causing locking engagement of said collet against said blade.
Claim 2
Dependent Claim
235 words
A removable arrowhead assembly comprising at least one blade having a recess extending inwardly from the rear edge thereof, a collet having at least one axial slot for the reception of said blade therein, said collet also having a cam surface and a threaded rearward end, a sleeve accommodated by said recess in said blade and having a cam surface adapted to abut against said cam surface of said collet for causing said collet to clamp tightly against said blade, said sleeve having at least one axial slot on the exterior thereof in axial alignment with said one axial slot in said collet, said slot in said sleeve receiving said blade for rigidly holding the latter in relationship to said sleeve, means located on the inner surface of said sleeve and interengaging with means on the exterior surface of said collet for preventing relative rotation between said collet and said sleeve, an insert having an internal thread for the reception of the threaded end of said collet, said insert being adapted to be secured to an arrow shaft, a metal impact ring mounted around said collet, said blade bearing against said metal impact ring when in assembled relationship, whereby said collet can be inserted in said sleeve and threadably engaged in said insert to tightly draw said collet cam surface against said sleeve cam surface for causing locking engagement of said collet against said blade.
Claim 3
Dependent Claim
236 words
A removable arrowhead assembly comprising a pair of blades arranged at right angles to one another, said blades having a sleeve-receiving recess extending inwardly from the rear thereof, a collet having axial slots for the reception of said blades therein, said collet also having a cam surface and a threaded rearward end, a sleeve accommodated by said recess in said blade and having a cam surface adapted to abut against said cam surface of said collet for causing said collet to clamp tightly against said blades, said sleeve having axial slots on the exterior thereof in axial alignment with said axial slots in said collet, said slots receiving said blades for rigidly holding the latter in right angled relationship to one another, means located on the inner surface of said sleeve and interengaging with means on the exterior surface of said collet for preventing relative rotation between said collet and said sleeve, an insert having an internal thread for the reception of the thread and of said collet, said insert being adapted to be secured to an arrow shaft, a metal impact ring mounted around said collet, said blades bearing against said metal impact ring when in assembled relationship, whereby said collet can be inserted in said sleeve and threadably engaged in said insert to tightly draw said collet cam surface against said sleeve cam surface for causing locking engagement of said collet against said blades.
Claim 4
Dependent Claim
236 words
A removable arrowhead assembly comprising a pair of blades arranged at right angles to one another, said blades having a sleeve-receiving recess extending inwardly from the rear thereof, a collet having axial slots for the reception of said blades therein, said collet also having a cam surface and a threaded rearward end, a sleeve accommodated by said recess in said blade and having a cam surface adapted to abut against said cam surface of said collet for causing said collet to clamp tightly against said blades, said sleeve having axial slots on the exterior thereof in axial alignment with said axial slots in said collet, said slots receiving said blades for rigidly holding the latter in right angled relationship to one another, means located on the inner surface of said sleeve and interengaging with means on the exterior surface of said collet for preventing relative rotation between said collet and said sleeve, an insert having an internal thread for the reception of the thread and of said collet, said insert being adapted to be secured to an arrow shaft, a metal impact ring mounted around said collet, said blades bearing against said metal impact ring when in assembled relationship, whereby said collet can be inserted in said sleeve and threadably engaged in said insert to tightly draw said collet cam surface against said sleeve cam surface for causing locking engagement of said collet against said blades.
Claim 5
Dependent Claim
64 words
The assembly set forth in claim 2 wherein said pair of blades includes a main blade and a secondary blade and wherein said secondary blade includes a slot extending rearwardly from the point thereof whereby said blades can be interengaged at right angles, and wherein each blade has a recess extending inwardly from the rear thereof, which recesses cooperate to define said sleeve-receiving recess.
