Abstract
A cable tensioning device having a frame, a cable-winding drum carried in the frame, ratchet wheel means attached to the drum, a reciprocable handle bearing a driving pawl for advancing the ratchet wheel means, and a holding pawl normally limiting rotation of the drum to a single direction. The ratchet wheel means may comprise a pair of toothed ratchet wheels respectively spaced on either side of the drum, and engageable with a driving pawl having similarly spaced teeth to provide symmetrical driving of the drum. Cable releasing means are shown permitting controlled unwinding of cable from the drum and comprising first spring means urging the holding pawl in toothed engagement with the ratchet wheel means, second preloaded spring means carried by the holding pawl, and index means responsive to movement of the handle to move the second spring means against its preload and thereby to disengage the holding pawl from the ratchet wheel means when the pressure between teeth of the holding pawl and ratchet wheel means is relieved. Details of construction are provided to enable the device to be manufactured from relatively few parts. The cable-winding drum may be manufactured from a pair of stamped plates, each plate having a generally semi-cylindrical shape forming approximately one-half of the cylindrical periphery of the drum, and edges of the plates being rigidly attached to ratchet wheels on either side of the drum.
