Abstract
A plurality of tubular, spaced apart cutting links are coaxially fastened to a continuous cable and are driven around a plurality of sprockets by a motor driven sprocket. Each cutting link includes cutting teeth at the forward end of the link and a chip or sawdust clearing edge at the rear of the link.
Claims7
An improved cable saw of the type having a flexible cable, a plurality of tubular cutting links threaded on the cable at spaced apart intervals and motor means for driving the links in a forward direction, wherein the improvement comprises
- nonrotatably attaching the cutting links to the cable, the cutting links having cutting teeth at their leading ends and an enlarged diameter section adjacent their trailing ends to clear the cut made by the cutting teeth, and the motor means includes a motor driven, slotted sprocket wheel whose slotted sprockets carry the cable in the sprocket wheel slot and sequentially engage the cable immediately behind each cutting link trailing end and abut the enlarged diameter section of each cutting link to pull the cable.
An improved cable saw of the type having a flexible cable, a plurality of spaced apart, tubular cutting links mounted coaxially on the cable, rotatable means for supporting the cable in tension, and motor means for driving the cutting links in a forward direction, wherein the improvement comprises
- securely attaching the cutting links to the cable, a plurality of sprocket wheels for supporting the cable in tension, each sprocket wheel having a plurality of sprocket teeth projecting from its circumference, each sprocket tooth having a U-shaped channel therein in the circumferential direction for carrying the cable with the cutting links out of contact with the circumference of the sprocket wheel, the cutting links being spaced apart by a distance which is greater than the length of the cutting links and the U-shaped channels being wider than the cable's diameter and narrower than the cutting link's diameter, means for rotatably mounting the sprocket wheels, motor means for driving one of the sprocket wheels so that the sprocket teeth of the driven wheel sequentially engage the cable and abut each cutting link trailing end to pull the cable about the sprocket wheels, whereby the cutting links are driven about the sprocket wheels and are each given a slight snap in leaving each sprocket wheel to clear debris from the cutting link.
