Arrow tip having replaceable cutting blades

Claim 2

An arrow tip adapted to receive a plurality of replaceable cutting blades comprising: an elongated body having coaxial front and rear end portions and a plurality of blade-receiving grooves extending along the periphery of the body from the front end portion toward the rear end portion, the body also having another groove extending circumaxially around the body; blade locking means having an annular shape and extending around the body in the circumaxial groove, the locking means having a diScontinuity and being rotatable in the circumaxial groove between positions about the body to register the discontinuity individually with each blade and lock or unlock a blade in a selected bladereceiving groove at each position; and blade retaining means connected to the front end portion of the body and cooperating with each of the plurality of blade-receiving grooves in the body for holding replaceable blades at the front end portion of the body.

Claim 3

An arrow tip as defined in claim 1 wherein said blade retaining means comprises a nose piece connected to and projecting axially from the forward end portion of the elongated body.

Claim 4

An arrow tip as defined in claim 2 wherein the nose piece has a trailing skirt portion defining an opening registering with the plurality of the blade-receiving grooves at the front end portion of the body.

Claim 5

An arrow tip as defined in claim 1 wherein the rear end portion of the body defines a mounting bore extending axially within the rear end portion.

Claim 6

An arrow tip as defined in claim 1 wherein the blade locking means comprises a resilient snap ring mating with the circumaxial groove.

Claim 7

An arrow tip as defined in claim 1 wherein the circumaxial groove of the elongated body intersects each of the blade-receiving grooves.

Claim 8

A broadhead arrow tip comprising: an elongated body member having a longitudinal body axis and a plurality of grooves extending longitudinally along the outer surface of the body member, the outer surface also including a circumaxial groove intersecting the longitudinal grooves; a plurality of cutting blades positioned respectively in the plurality of longitudinal grooves and projecting radially from the body member, each blade having a projecting cutting edge extending at an angle to the longitudinal axis of the body member from a blade tip adjacent one axial end of the body member, and an attachment aperture registering with the circumaxial groove; a resilient, split ring rotatably mounted on the body member in the circumaxial groove and extending through each one of the attachment apertures in the cutting blades for rotatable movement to align the split in the ring with a selected blade for individual disengagement of the selected blade and the ring; and a fastening secured to said one axial end of the body member and engaging the blade tips of the cutting blades.

Claim 9

A broadhead arrow tip comprising: an elongated body member having a longitudinal body axis and a plurality of grooves extending longitudinally along the outer surface of the body member, the outer surface also including a circumaxial groove intersecting the longitudinal grooves; a plurality of cutting blades positioned respectively in the plurality of longitudinal grooves and projecting radially from the body member, each blade having a projecting cutting edge extending at an angle to the longitudinal axis of the body member from a blade tip adjacent one axial end of the body member, and an attachment aperture registering with the circumaxial groove; a resilient, split ring rotatably mounted on the body member in the circumaxial groove and extending through each one of the attachment apertures in the cutting blades for rotatable movement to align the split in the ring with a selected blade for individual disengagement of the selected blade and the ring; and a fastening secured to said one axial end of the body member and engaging the blade tips of the cutting blades.

Claim 10

A broadhead arrow tip as defined in claim 7 wherein the fastening has a projectile shape and extends coaxially of the body member from said one axial end.

Claim 11

A broadhead arrow tip as defined in claim 8 wherein the body member has an axially extending mounting bore at the axial end opposite the fastening.

Claim 12

A broadhead arrow tip as defined in claim 7 wherein the longitudinal grooves of the body member have a greater depth below the surface of the body member than the circumaxial groove at the intersections of the grooves.
