Abstract:
1. A tension adjusting apparatus for a flexible power transmission means, said tension adjusting apparatus comprising: a set screw; a base plate being a first vertical plate having a first side and a second side, a through hole going through said first and second side of said base plate for accepting an axle, said first side of said base plate having a first raised protrusion with a threaded through hole in said first raised protrusion for accepting said set screw and a recessed slot for accepting a slidable bar; said slidable bar being a second vertical plate having a first and second side, an elongated through hole slot going through said first and second side of said slidable bar for accepting said axle, said first side of said slidable bar having second and third raised protrusions, said second raised protrusion utilized for contacting an inside surface of a yoke and said third raised protrusion for contacting with the end of said set screw located in said base plate, said second side of said slidable bar slideably received in said recessed slot in said base plate; wherein when the set screw is turned into the base plate, the set screw makes contact with the slidable bar and pushes the slidable bar into the inside curved surface of the open ended yoke, and once the slidable bar has made contact with an inside curved surface of the yoke, any further turning in of the set screw causes the base plate to move backward pulling the axle with it, thereby tightening the flexible power transmission means.
