Abstract
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.

Claim 1
Independent Claim
130 words
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.
Claim 2
Dependent Claim
