Abstract
In a box, open at least at one end, is a drum cam, into each end of which is secured a stub shaft from the hub of a hand lever; the hub of a hand lever; the hubs being journaled in opposite side walls of the box; the hand levers being outside the box for turning the cam manually to release the webbing; cross-sectionally the cam is a substantially diagonal cam, the opposite projections or apices of which are rounded and spaced apart to a distance equal to or greater than the height of the box; smooth gripping surfaces adjacent the respective projections are diagonally spaced apart to leave a clearance less than the thickness of the webbing to be clamping against the top and bottom of the box when tension on the webbing around the cam urges the projections toward said top and bottom; a light multiple ribbon spring between an end wall of the box and the cam urges the webbing against the surface of the cam with light pressure; a pin spaced from the cam anchors the end of the webbing, so that the webbing extends from said anchor pin to be connected to parts to be held together and then around the cam in the box out to form a tab.
