An apparatus for operating a line driven device such as a traverse rod. The apparatus includes a frame member adapted to be mounted on or near the device, a reaction arm mounted on the frame member for pivotal movement, a motor mounted on the reaction arm and having an output shaft with a drive member, the reaction arm being adapted for pivotal movement about the output shaft, and a tensioning member disposed in spaced relation to the drive member. With this arrangement, the tensioning member can engage a line to maintain the line in tension in response to pivotal movement of the reaction arm.

Apparatus for operating a line driven device

A motor and roller support includes a reversible lock clutch mechanism having a housing including an annular portion having a plurality of alternately deep and shallow recesses and a spindle axially received in the housing and having at least one flexible pawl positioned to cooperate with the plurality of recesses of the housing, with the pawl being unflexed when radially aligned with any of the deep recesses of the housing, and being angularly flexed upon being positioned in any of the shallow recesses of the housing. Upon alignment of the pawl with any of the deep recesses of the housing, relative rotation between the housing and the spindle can be initiated in either direction. However, upon the pawl being positioned with its end residing in a shallow recess of the housing and abutting the recess surface, relative rotation between the housing and the spindle can be initiated in only one direction therefrom. In the motor and roller support, the housing is adapted to engage a terminal portion of a roller and the spindle has means for engaging a supporting bracket extending from one end of the spindle outwardly of the housing, the means for engaging a motor, such as a spring motor. The motor and roller support is useful for supporting a strip, such as a window shade, a screen, and the like, secured to a roller for rolling and unrolling with respect to the roller.
