Abstract
A solid arrow shaft front extension portion or ferrule having a plurality of offset slots parallel to tangents to the shaft for replaceable and interchangeable devices or blades of general triangular or other shape held at their forward end in the slots by an interchangeable screw-in tip and at their rearward end by a deformable collar urged into locking the devices in position by screwing of the rear shank of the shaft extension or arrowhead into the front socket of the arrow shaft. If desired, between the collar and the end of the arrow shaft there may be provided one or more weight washers and/or a resilient locking washer for adjusting the angularity of the blades with respect to the nock at the rear of the arrow shaft.

31. A broadhead arrowhead comprising:
-
(A) a central shaft portion externally threaded at its rear end for threading into an arrow shaft, internally threaded at its forward end, and having a plurality of axially extending slots in planes spaced equal radial distances from the axis of said shaft substantially along the central portion of said shaft portion, (B) a plurality of blades seatable in said slots having acute angled projections at each end in said blades, (C) a tip having an annular groove and threaded extension at its rear end for threading into the internal threaded forward end of said shaft portion whereby the front acute angled projections of said blades are anchored in said annular groove, (D) a deformable annular collar axially slidably mounted around the rear end of said shaft portion overlapping the rear acute angled ends of said blades to anchor their rear ends in said slots, and (E) a resilient locking washer axially slidably mounted between said collar and the front end of the arrow shaft for permitting angular adjustment of said blades with respect to said arrow shaft while the collar is axially urged into deformable contact with the rear of said blades by the threading of said externally threaded rear portion of said shaft portion into the front end of said arrow shaft.
