Abstract

The present invention comprises a two-track cam assembly wherein the cam assembly has a bowstring component for housing the bowstring and a power cable component that allows for the take up and let out of the power cable on opposing ends of the power cable component, effectively creating a two-track cam assembly. The efficiency rating of the device achieves 95.8%. The cam assembly can come in a unitary or modular form and further each component (i.e. the bowstring or power cable component) can be in a circular or non-circular form.

Claims

1. A cam assembly comprising:

a bowstring cam component having a track for receiving a bowstring; and

a power cable cam component having a take up portion and a let out portion;

wherein the take up and let out portion each have a track for receiving a power cable.

2. The cam assembly of claim 1 wherein the let out portion of the power cable cam component is modular and attached to the power cable cam component.

3. The cam assembly of claim 1 wherein the tracks on the take up and let out portion are connected as a continuous track around the perimeter of the power cable cam assembly.

4. The cam assembly of claim 1 wherein the tracks on the take up and let out portion the power cable cam component is not connected.

5. The cam assembly of claim 1 wherein the bowstring component is in a shape selected from the group consisting of circular or non-circular.

6. The cam assembly of claim 1 wherein the power cable cam component is in a shape selected from the group consisting of circular or non-circular.

7. The cam assembly of claim 1 further comprising a draw stop pin.

8. The cam assembly of claim 7 wherein the draw stop pin is attached to the let out portion of the power cable cam component.

9. The cam assembly of claim 1 further comprising a second power cable cam assembly having a take up portion and a let out portion, wherein the take up and let out portion have a track for receiving a power cable.

10. The cam assembly of claim 9 wherein the tracks of the take up and let out portion at least one of the power cable cam assemblies are connected as a continuous track around the perimeter of the power cable cam assembly.

11. The cam assembly of claim 9 wherein the tracks of the take up and let out portion at least one of the power cable cam assemblies are not connected as a continuous track around the perimeter of the power cable cam assembly.

12. A compound bow comprising:

A handle portion;

A limb portion;

At least two cam assemblies, each comprising;

a bowstring cam component having a track for receiving a bowstring; and

a power cable cam component having a take up portion and a let out portion, wherein the take up and let out portion have a track for receiving a power cable;

a draw stop pin

a take up terminating post; and

a let out terminating post;

an axel;

at least two power cables; and

a bowstring.

13. The compound bow of claim 12 wherein the cam assembly is placed on an axel on the limb portion of the bow;

wherein one power cable is attached to a take up terminating post and wrapped around the take up portion of the power cable cam component on a first cam assembly and at its other end is attached to the let out terminating post and wrapped around the let out portion of the power cable cam component on the second cam assembly.

14. The compound bow of claim 13 wherein the second power cable is attached to the let out terminating post and is wrapped around the let out portion of the power cable component on the first cam assembly, and at its other end is attached to the take up terminating post and wrapped around the take up portion of the power cable cam component of the second cam assembly.

15. The compound bow of claim 12 wherein the cam assemblies each have a second power cable cam component and at least four power cables.
