ABSTRACT:
This box type belt adjuster includes a box open at least at one end so as to form a passage therein for a belt or other webbing around a cam which latter is supported on a transverse shaft in the box. A snap-on cap covers the inner end of the passage and encloses a space for a yoke engaging the cam for turning it in the passage. The height of the passage and the distance between the risers of the cam are so related that when the cam is turned to move the risers toward the opposite top and bottom of the passage the clearance is slightly less than the thickness of the belt or webbing whereby when the cam is so turned the belt is jammed between the top and bottom of the passage and the risers of the cam. A manipulating extension extends from the lever to the outside of the cap for turning the cam in a direction to increase the clearance between the risers and the respective sides of the passage. The side walls of the body of the adjuster have ears extended beyond the cap and a transverse rib between them is adapted to accommodate another webbing. The cam is self centering on said shaft through an oblong axial hole therethrough.
