Abstract

A cam pin having a cam pin shaft, wherein said shaft extends from a terminal end surface, along a longitudinal axis, to a shoulder; a firing pin aperture formed through said cam pin shaft; and a head, wherein said head extends from said shoulder, along said longitudinal axis, to a crown, wherein a surface of said crown is finished with a substantially smooth surface.

Claims

1. A cam pin, comprising:

a cam pin shaft, wherein said shaft extends from a terminal end surface, along a longitudinal axis, to a shoulder;

a firing pin aperture formed through said cam pin shaft; and

a head, wherein said head extends from said shoulder to a crown, wherein said head is formed as an integral portion of said cam pin shaft, and wherein a surface disposed between said shoulder and said crown is a continuous surface, having a constant radius, curved profile, wherein a cam pin flat is provided in a portion of said head, and wherein a surface of said cam pin flat is formed parallel to said longitudinal axis of said cam pin and perpendicular to a longitudinal axis of said firing pin aperture.

2. The cam pin of claim 1, wherein said shoulder extends from said cam pin shaft perpendicular to said longitudinal axis of said cam pin.

3. The cam pin of claim 1, wherein said crown extends directly from said shoulder and presents a constant radius curved profile.

4. The cam pin of claim 1, wherein said crown provides a domed, bulbous, or button shape to a terminating portion of said head.

5. The cam pin of claim 1, wherein said crown comprises an indention or dimple formed in a terminating end portion.

6. The cam pin of claim 1, wherein said shoulder is spaced from said crown and a head transition area is formed between said shoulder and said crown.

7. The cam pin of claim 6, wherein said head transition area is formed perpendicular to said longitudinal axis.
