Motor Saw for Felling Trees.
In attempting to develop an electrically operated device for bucking and felling trees, a lumber company in Marshfield, Ore., constructed a portable motor-driven chain saw, which will cut through a two-foot log in less than a minute, declares the Electrical World. The cutting element consists of a motor-driven saw-toothed chain traveling around the peripheries of two pulleys, one at each end of the frame. The motor is connected direct to one of the pulleys and is supplied with electricity through a flexible cord. The apparatus weighs only eighty pounds complete.
