  • Pivotable motor mounting apparatus
    Patent number: 6705581
    Abstract: Apparatus for mounting an electric motor, which is adapted to drive an endless belt at a predetermined tension, to a stationary frame, includes a housing that is adapted to receive the motor. A drive shaft extends from the front end of the housing and is adapted to drive the belt. An elongated base mount is integrally formed on the outside surface of the housing and extends from the front of the housing for pivotally coupling the housing to the stationary frame. The base mount has a first end and a second end, and a bore which extends longitudinally at least partially through the base mount from the first end and the second end of the base mount. A substantially rigid tab is fixedly attached to the cylindrical housing at a substantially opposite side from the base mount. The tension on the belt is set by applying a biasing force on the tab to pivot the motor about the axis of the base mount.
