Roger L Walworth

US Patent:

60509155, Apr 18, 2000

Filed:

Sep 9, 1998

Appl. No.:

9/150143

Inventors:

Roger L. Walworth - Ledyard CT
Richard Boulanger - Norwich CT

International Classification:

F16H 708
F16H 714
F16M 100

US Classification:

474114

Abstract:

A motor mounting apparatus supports a motor relative to a base for relative rotation about a pivot axis to control tension in an endless loop driving element. A driving element emcompasses a drive member driven by the motor about a drive member axis and a driven member coupled to a load and driven by the driving member about a driven member axis to transmit power from the motor to the load. The apparatus includes a threaded shaft rotatable by a user about a shaft axis. The shaft axis is fixed relative to a first of the base and motor. A rider is carried by the threaded shaft so that rotation of the threaded shaft about the shaft axis produces longitudinal translation of the rider along the shaft axis relative to such first one of the base and motor. A rigid link has a first end pivotally coupled to the rider and a second end pivotally coupled to a second one of the base and motor.

The apparatus includes a threaded shaft rotatable by a user about a shaft axis. The shaft axis is fixed relative to a first of the base and motor. A rider is carried by the threaded shaft so that rotation of the threaded shaft about the shaft axis produces longitundinal translation of the rider along the shaft axis relative to such first one of the base and motor. A rigid link has a first end pivotally coupled to the rider and a second end pivotally coupled to a second one of the base and motor.
