[Fig. 3147] is a sectional view of the slides on the slideway m and [Fig. 3148] a plan of the same. The hand wheel n corresponds to n in [Fig. 3145]. Upon the vertical slideway (in [Fig. 3145]) of the standard fits the slide p, which has a horizontal slideway for the slide r, which is free to slide automatically, having no screw or other device to restrain it, save the guide frame l, and therefore as this frame is lowered to feed the saw the slide r moves automatically to accommodate the arc of a circle in which the guide moves on account of being pivoted at b.

Horizontal Saw Frame.—This machine is designed for the more expensive woods, such as mahogany, and is finding much favor because it will cut at a very high speed, the saw travelling about 150 feet per minute.
