Rip′ping-saw.

A saw for cutting wood lengthwise of the grain. Fig. 4338 illustrates a band-saw adapted for this purpose. The upper pulley is journaled in yielding bearings, adjustable in hight by the screw a, to impart the required tension. In front of the saw is a hinged gate, to prevent injury to the workman in case of slipping or breakage. The guide b is adjustable to suit different thicknesses of timber. The ripping-gage c d is [1946] screwed to the table, and, by means of a thumb-nut, is adjusted to cut square or beveling, and the work is held firmly against the fence e by springs adjustable by thumb-screws.

Circular rip-saws differ principally in regard to the modes of hanging and the provisions for feeding and guiding the timber. In a, Fig. 4339, the guiding is effected by the fence b, which is moved parallel to the saw and held by a parallel-motion device at the end of the table.

The lower figure has a corresponding fence c, to be used for ripping, and a guide e, which can be moved transversely of the table, and is pivoted, so that the timber may be presented at any angle to the saw, which can thus be used for cross cutting.

d is a fence, the face of which is adjustable to any angle with the bed.
