Abstract

An arrowhead assembly having a shank connectible to a shaft of an arrow and to an arrowhead tip. A substantially rigid shield is slidably mounted on the shank and biased toward the tip as by a coiled spring for retarding motion of the arrow on the arrow entering an animal or other target. When the assembly includes tips such as a fish point having diverging barbs extending from the point at the tip an adapter unit is advantageously employed to space the tip from the shank.

Claims

1. An arrow assembly including a shaft having a forward end, an elongated shank having front and rear ends, the rear end of said shank being removably secured to the forward end of said shaft with said shank defining a forward lengthwise projecting extension of said shaft, the rear end portion of said shank including means defining a first outwardly projecting abutment, a shield slidably mounted on said shank for movement therealong forward of said abutment, resilient means on said shank engaged with said abutment and shield yieldingly biasing the latter forwardly along said shank, an arrowhead tip removably mounted on the forward end of said shank and including a rear portion defining a second outwardly projecting abutment establishing a limit stop of movement of said shield forwardly along said shank.

2. The combination of claim 1 wherein said arrowhead tip comprises a broadhead tip.

3. A structure as defined in claim 1 wherein said first abutment comprises a radially outwardly projecting circumferential flange carried by said shank, said resilient means comprising a coiled compression spring arranged on the shank between the flange and the shield.

4. A structure as defined in claim 3, wherein the shield comprises an annular cup constructed from a substantially rigid material and provided with a central opening slidably receiving the shank therethrough.

5. A structure as defined in claim 1, wherein the tip includes a cylindrical blunt head.

6. A structure as defined in claim 1, wherein the tip comprises a fish point provided with at least one barb and including a base portion flared toward the rear end thereof and terminating in a threaded rod, a sleeve having a threaded socket engaging the threaded rod, and an adapter provided with a threaded, shouldered extension threadedly engaged in the front end of the shank, the sleeve being telescoped over and affixed to the adapter with the rear end of said sleeve defining sai second abutment.

7. A structure as defined in claim 1, wherein the shield is an annular cup constructed from a substantially rigid material and provided with a central opening slidably receiving the shank therethrough.

8. An arrowhead assembly, comprising, in combination:

a. am arrowhead tip;

b. a shank having a threaded socket, the shank connectible to a shaft of an arrow and connected to the arrowhead tip;

c. a shield slidably mounted on the shank for movement with respect thereto; and

d. resilient means arranged on the shank and abutting the shield for biasing the shield toward the tip and permitting the shield to retard motion of the arrow when penetrating a target, the tip including a cylindrical blunt head and a threaded, shouldered extension engaged with the socket of the shank.

9. An arrowhead assembly, comprising, in combination:

a. an arrowhead tip;

b. a shank having a threaded socket, the shank connectible to a shaft of an arrow and connected to the arrowhead tip;

c. a shield slidably mounted on the shank for movement with respect thereto; and

d. resilient means arranged on the shank and abutting the shield for biasing the shield toward the tip and permitting the shield to retard motion of the arrow when penetrating a target, the tip being a fish point provided with at least one barb and including a base portion flared toward an end thereof terminating in a threaded rod, and further including a sleeve having a threaded socket engaging the threaded rod, and an adapter provided with a threaded, shouldered extension engageable with the socket of the shank, the sleeve being arranged over and affixed to the adapter and between and abutting the tip and the shield.
