Re-saw′ing–ma-chine′.
(Wood-working.) A machine for cutting up squared timber into small stuff or boards. In the machine, Fig. 4266, a reciprocating-saw is employed. The longitudinal feed is effected by the usual vertical rollers, rotated by gear connection with a shaft caused to revolve by a pawl at the end of a lever connected with the journal of the pitman, which causes the reciprocation of the saw-frame. A hand-crank and screw control the transverse feed of the stuff. In Fig. 4267, the squared piece to be cut up is drawn between the adjustable feed-rollers a b, by which it is presented to the saw c; the sword d guides the severed board and prevents its fouling the operative mechanism. The roller-turning and sawrotat-ing gears are driven by the band pulleys e e, and the transverse movement of the carriage f may be effected by turning the hand-wheel g.
