Ice-cut′--ting Machine′.
One for cutting kerfs in pond ice, to reduce the surface to strips which are afterwards broken into blocks by the axe or spade. In the example, it is a circular saw on a sled, which is drawn by a horse. The saw receives motion from a serrated wheel which engages the ice, and is vertically adjustable by a rack and pinion operating its journal-frame. See also b, Fig. 2658.Ice-elevator. |
