Broadhead arrowhead
First Claim
1. A broadhead arrowhead comprising;
- a ferrule having a main body provided with an outer periphery, opposite front and rear end portions extending from said main body,said ferrule including an axial passageway extending substantially through the length of said main body and projecting through said front end portion,said ferrule main body and front end portion provided with a plurality of outwardly radiating slots communicating with said axial passageway, adjacent pairs of said plurality of slots defining a similar included angle therebetween,a plurality of individual blade members each including a main body portion joined to an angularly offset mounting flange portion along a longitudinal bend line, said main body portion and mounting flange portion of each said blade member having a substantially equal thickness and defining an included angle therebetween which is equal to said included angle between adjacent pairs of said plurality of ferrule slots,said slots having a width no less than twice the thickness of any one said blade member main body portion or mounting flange portion,a plurality of said blade members equal in number to the number of said slots inserted within said ferrule slots with said bend line of each said blade member disposed within said axial passageway and with said main body portion and mounting flange portion of each said blade member occupying adjacent ones of said slots, wherebywith all said plurality of blade members disposed within said plurality of ferrule slots, each said slot is occupied by one said mounting flange portion of one said blade member and one said main body portion of another one said blade member, andmeans engaging said ferrule precluding unwanted axial displacement of said blade members disposed within said ferrule slots.

Abstract
A broadhead arrowhead includes an elongated ferrule to which are removably attachable a plurality of separate blade members. Each blade comprises an enlarged main portion preferably exhibiting a sharpened outer edge, and a longitudinally extending mounting flange portion. The latter is offset from the former by a fixed angular amount and this offset corresponds to the angular disposition between any two adjacent ones of a plurality of radial slots formed in the ferrule. All of the slots communicate with a central, axial passageway within the ferrule and which extends through its tip. Attachment of the blades is accomplished by sliding each blade rearwardly through the ferrule leading end, with the apex of the angularly offset blade portions passing into the ferrule axial passageway as the two blade portions slide into two separate, adjacent ferrule slots. Remaining blades are similarly attached, with the flange portion of one blade being inserted into the same slot as occupied by the main body portion of an adjacent blade. The width of the ferrule slots is formed to insure a close sliding fit when the above portions of two blades are disposed therein. Secure anchorage of the installed blades is achieved as a notch formation at the rear of each blade straddles a mating formation adjacent the rear of the ferrule slots and tangs on the front of the blades are captively retained upon the application of a removable tip member to the leading end of the ferrule.

11. A broadhead arrowhead comprising;
-
an elongated ferrule provided with an outer periphery, said ferrule having a front end and including a central axial passageway opening through said front end, a plurality of slots communicating with and radiating outwardly from said central axial passageway and through said outer periphery, adjacent ones of said slots defining an angular offset disposition therebetween when said ferrule is viewed in end elevation, a plurality of blade members each including first and second angularly offset portions when viewed in end elevation, said blade members mounted within said ferrule each with its said first and second angularly offset portions respectively inserted within an adjacent pair of said ferrule slots and with one said blade member first offset portion disposed in a same one said slot as one said second offset portion of another one said blade member, and said plurality of blade members mounted within said ferrule having said second offset portions substantially flush with said ferrule outer periphery with said first offset portions radially projecting a substantial distance from said ferrule outer periphery. - View Dependent Claims (12, 13)
