Abstract

A broadhead arrow head structure armed with razor type blades spaced thereabout, each of the blades being positioned into a slot, each blade having an underlying forwardly projecting tongue portion, the tongue portions extending into an undercut recess of the slots, and the arrow head structure being threaded into an arrow shaft to lock the blades in operating position.

Claims

1. A broadhead arrow head assembly for attachment to an arrow shaft, having in combination

a substantially cylindrical body portion having a tip portion,

a bore extending inwardly of said body portion from said tip portion,

a plurality of longitudinal slots spaced about said body portion,

rearward portions of said slots extending deep enough into said body portion to communicate with said bore,

a further rearward extension of said body portion having a threaded end portion,

a shaft having means in one end thereof to receive said threaded end portion,

blade members disposed into said slots,

said blade members respectively having elongated forwardly extending tongue portions,

said tongue portions entering said bore and underlying the adjacent body portion to be secured therein, and

a shaft having means in one end thereof receiving said threaded end portion and engaging and locking said blade members in operating position.

2. A broadhead arrow head assembly for attachment to an arrow shaft, having in combination

a substantially cylindrical body portion,

a bore extending into said body portion from the forward end thereof,

a plurality of slots spaced about said body portion longitudinally thereof,

the rearward portions of said slots being deeper than the forward portions thereof,

said rearward portions of said slots communicating with said bore,

blade members disposed into said slots,

said blade members having elongated forwardly projecting tongue portions which enter said bore,

a threaded rear end portion of said body portion,

an arrow shaft,

means embedded in the forward end of said shaft receiving said threaded end portion, and

said blades being engaged by said means and locked into operating position.

3. The structure of claim 2, wherein

said body portion has a rearward portion reduced in diameter,

whereby said slots in said reduced body portion communicate with said bore.

4. The structure of claim 2, wherein

said blade members extend rearwardly to said threaded portion,

a tapped receptacle being embedded into said forward end portion of said shaft, and

said receptacle engaging said rear end portions of said blades.

5. The structure of claim 4, including

a projection tail portion of said blade being engaged by said receptacle.

6. The structure of claim 2, wherein

said threaded portion of said body portion being reduced to a size to be received into said shaft.

7. The structure of claim 2, wherein

said tongue portions each have such a length that upon insertion into said bore, they underlie and engage the adjacent wall of said bore for a locking engagement which prevents the forward end portions of said blades from being raised out of said slots.
