Abstract

A three way post on each side of a wheel for a compound bow enables connections to a loop and a ferrule, and provides a clamp connection using a setscrew in a threaded hole in the post. The post is located along a line perpendicular to a diameter intersecting the axle upon which the wheel turns.

Claims

1. In a compound archery bow having a handle, first and second limbs each having a first end connected to said handle, an axle connected to a second end, and a wheel having a hub mounted on said axle, and lacing connecting said wheels with said first and second limbs, the improvement comprising:

a first post on one side of the hub of each wheel and a second post on the opposite side of the hub of each wheel, said first post including a first hole and said second post including a second hole collinear with said first hole and extending through said hub; and

said lacing being attached to at least one of said posts on each wheel.

2. The compound archery bow as set forth in claim 1 wherein said first hole is threaded.

3. The compound archery bow as set forth in claim 2 wherein said second hole is larger in diameter than said first hole.

4. The compound archery bow as set forth in claim 1 wherein said first and second posts each include a circumferential groove.

5. The compound archery bow as set forth in claim 1 wherein said first and second posts each include a slot to provide lateral access to said first and second holes, respectively.

6. The compound archery bow as set forth in claim 1 wherein each wheel includes a pair of pulleys and a passageway through the hub of each wheel adjacent said first and second posts.

7. The compound archery bow as set forth in claim 6 wherein said hub of each wheel includes a channel interconnecting one of said slots and said passageway.

8. A compound archery bow comprising:

a handle;

first and second limbs each having a first end connected to said handle, an axle connected across the width of a second end, and a wheel mounted on and rotatable on said axle;

lacing for interconnecting said wheels;

each of said wheels including a pair of pulleys each having;

a rim including a circumferential groove, said lacing engaging said rim at a contact point and extending from said contact point part way around said pulley in said groove;

a first hole extending through both of said pulleys, said wheel being mounted with its respective axle through said first hole;

a first diameter of each pulley intersecting the center of said hole, said first diameter including the largest radius of each pulley as measured from said center;

a second diameter of each pulley perpendicular to said first diameter, at least a portion of said lacing lying along said second diameter;

a post located along said second diameter, said post including a second hole.

9. The compound archery bow as set forth in claim 8 wherein the second holes of the pulleys in each wheel are collinear.

10. The compound archery bow as set forth in claim 9 wherein at least one post of each wheel includes a slot for providing lateral access to said second hole.

11. The compound archery bow as set forth in claim 8 wherein the second hole of one pulley of each wheel is threaded.

12. A three way wheel for a compound archery bow comprising:

first and second adjoining pulleys having a common hole for engaging an axle and having first and second major surfaces;

a first diameter of each pulley intersecting the center of said common hole, said first diameter including the largest radius of each pulley as measured from said center;

a second diameter of each pulley perpendicular to said first diameter;

a recess of predetermined depth in respective major surfaces of said pulleys, said recesses not including said common hole;

a second hole parallel to said common hole located in said recess along said second diameter of each pulley; and

a wall surrounding each second hole, said wall having a height approximately equal to said predetermined depth.

13. The wheel as set forth in claim 12 wherein said second holes are collinear and one of said second holes is threaded.

14. The wheel as set forth in claim 13 wherein the other of said second holes has a diameter larger than the diameter of said one of said second holes.

15. The wheel as set forth in claim 12 wherein each of said walls includes a circumferential groove.

16. The wheel as set forth in claim 12 wherein each wall includes a slot for providing lateral access to said second holes.
