Abstract

924,727. Sawing. UNION INDUSTRIES (PROPRIETARY) Ltd. May 25, 1961 [June 1, 1960], No. 18891/61. Class 145. A beam 4 is pressed against a fence 3 and fed into a saw 5 by at least one toothed or rubbertyred roller 14 mounted on a carriage 1 guided by rollers 2a, 2b and the driving means for the roller comprises an endless chain 23 which is stretched over two sprockets 8, -15 journalled on the carriage; the chain is driven by a sprocket 24 rotated through reduction gearing 26 and adjustable wooden brake shoes 18 are provided for the spindle 17 of the sprocket 15 so that by applying restraint to the rotation of this spindle the chain 23 and sprocket 24 tend to act as a rack-and-pinion and cause the feed roller to engage the beam with a pressure which does not vary as successive boards are cut from it. As shown, two rollers 14 are driven by spur gearing 11, 12 from the sprocket 8 and are mounted on an arm 10 pivoted on the carriago so that it rocks to accommodate abutting beams of differing thickness. A bifurcated lever 27 engaging a pin 30 on the carriage is provided for moving the carriage back to allow introduction of a new beam. A guard plate 33 maintains the chain in engagement with the sprocket 24.
