Abstract

In some embodiments, a compound bow comprises a frame, a first limb supported by the frame and a second limb supported by the frame. The first limb supports a first rotatable member, and the first rotatable member comprises a cam. The compound bow further comprises a second rotatable member, a first pulley and a second pulley. A power cable is in communication with the cam. A bowstring contacts the first rotatable member, the second rotatable member, the first pulley and the second pulley. In some embodiments, the first pulley is supported by the first limb.

First claim

What is claimed is:

1. A crossbow comprising:
a stock;
a latch;
a bow portion attached to the stock, the bow portion comprising:
a frame;
a first limb supported by the frame;
a second limb supported by the frame;
a first rotatable member comprising a cam, the cam being eccentric with respect to a rotation axis of the first rotatable member, the first rotatable member supported by the first limb;
a second rotatable member;
a first pulley;
a second pulley;
a power cable in communication with the cam; and
a bowstring arranged to contact the first rotatable member, the second rotatable member, the first pulley and the second pulley.

2. The crossbow of claim 1 , wherein the first rotatable member is positioned closer to the latch than the first pulley.

3. The crossbow of claim 1 , the first pulley supported by the first limb.

4. The crossbow of claim 3 , the frame contacting the first limb at a location between the first rotatable member and the first pulley.

5. The crossbow of claim 3 , the first pulley located at an end of the first limb.

6. The crossbow of claim 1 , the second rotatable member supported by the second limb.

7. The crossbow of claim 6 , the second pulley supported by the second limb.

8. The crossbow of claim 7 , the frame contacting the second limb at a location between the second rotatable member and the second pulley.

9. The crossbow of claim 7 , the second pulley located at an end of the second limb.

10. An archery bow comprising:
a frame;
a first limb supported by the frame;
a second limb supported by the frame;
a first rotatable member comprising a cam, the cam being eccentric with respect to a rotation axis of the first rotatable member, the first rotatable member supported by the first limb;
a second rotatable member;
a first pulley;
a second pulley;
a power cable in communication with the cam; and
a bowstring arranged to contact the first rotatable member, the second rotatable member, the first pulley and the second pulley.

11. The archery bow of claim 10 , the first pulley supported by the first limb.

12. The archery bow of claim 11 , the first pulley located at an end of the first limb.

13. The archery bow of claim 11 , the first pulley and the first rotatable member positioned at opposite ends of the first limb.

14. The archery bow of claim 11 , the frame contacting the first limb at a location between the first rotatable member and the first pulley.

15. The archery bow of claim 10 , the second pulley supported by the second limb.

16. The archery bow of claim 15 , the second pulley located at an end of the second limb.

17. The archery bow of claim 15 , the second rotatable member supported by the second limb.

18. The archery bow of claim 17 , the second pulley and the second rotatable member positioned at opposite ends of the second limb.

19. The archery bow of claim 17 , the frame contacting the second limb at a location between the second rotatable member and the second pulley.
