Abstract
Arrowhead capable of being converted, by interchange of head elements, from an archery head to any selected one of various types of hunting heads. Comprises an elongated main body having an axially extending space and a plurality of longitudinal slots, both the slots and the axially extending space opening through the same end of the body, the slots also opening laterally both outwardly and into the axially extending space so that a blade assembly can be inserted into the main body via the slots and the axially extending space. The body also includes a stop surface, which may be a blind end of the axially extending space or a blind end of each slot or both, against which the blade assembly is clamped axially by a closure member which is releasably secured to the end of the main body through which the slots open.

11. In an arrowhead, the combination of an elongated main body adapted to be secured to the tip of a tubular arrow shaft, said tubular arrow shaft having a leading end portion,
said main body having a leading end, an intermediate portion and a trailing end, an axial space which opens through said leading end of body and extends for at least a substantial part of the length of the body, a plurality of slots which extend both longitudinally and laterally relative to the main body, open longidudinally through said leading end of the body and open both outwardly through the outer surface of the body and inwardly into the axial space, the trailing end portion of said main body shaped and dimensioned so as to be insertable into said leading end portion of said tubular arrow shaft and secured thereto, and at least one internal stop surface which is spaced from said leading end of the body toward the trailing end, faces toward said leading end and is axially exposed toward said one end via said axial space and said slots; -
a blade assembly comprising at least two blades and being constructed and arranged to be inserted into the main body via the open ends of the axial space and the slots until the blades are each accommodated by a different one of the slots and the assembly is engaged with said at least one stop surface; and a closure member releasably secured to said one end of the main body to close the open ends of the slots and secure the blade assembly in a position in which the assembly is clamped axially against said at least one stop surface.
