Broadhead arrowhead

Abstract

An arrowhead (10) is shown in the most preferred form including first and second blades (12, 14), a ferrule (16), and a collar (18). The leading ends of the blades (12, 14) are interconnected by slideably interlocking the blades (12, 14) together in slots (54, 58) formed in the blades (12, 14). The trailing ends of the blades (12, 14) are held in slots (62, 64) formed in the collar (18). The ferrule (16) is rotatably received in U-shaped sockets (38) formed in the blades (12, 14) and through the collar (18) and is adjustable therewith by threads (66, 78) formed in the ferrule (16) and collar (18). By rotation of the ferrule (16) relative to the collar (18) and the blades (12, 14), an expansion force is placed on the blades (12, 14). The slots (62, 64) of the collar (18) have a size to flushly receive the trailing ends of the blades (12, 14). Further, the trailing end (60) of the collar (18) is tapered and complementary to locking edges (30, 32) formed on the trailing ends of the blades (12, 14). The collar end (60) and the locking edges (30, 32) are engaged and held by the internally tapering face (76) of an integral flange (74) formed on the ferrule (16), with the trailing ends of the blades (12, 14) being sandwiched and held between the collar (18) and the flange (74) for locking the blades (12, 14) in the slots (62, 64) for preventing axial, radial, or circumferential movement of the trailing ends of the blades (12, 14) relative to the ferrule (16). The ferrule (16) may include threads (72) for threadable receipt within an internally threaded bore formed in the leading end of the arrow shaft.
