Image Description:
Fig. 4 represents a strong, well-designed rack bench by Messrs. C. Powis and Co., of London, especially adapted for the heaviest class of circular sawing. The timber is brought up and carried through the saw by means of a wrought-iron travelling bed, divided longitudinally by the saw, and made to travel over turned rollers by means of a strong self-acting rack gear. Other suitable rollers are fixed alongside the travelling bed, both behind and in front of saw, on to which the timber can be canted both before and after being sawn. The table can be arranged to travel at from 12 feet to 40 feet per minute, and after the cut is made the return motion is from 70 feet to 80 feet per minute. It is stopped or started by means of a treadle or lever under the immediate command of the sawyer. For breaking down heavy logs where few cuts are required, or where the scantlings are afterwards to be cut into thin boards in a deal frame, this class of bench is especially well suited. The travelling bed is fixed very little above the floor line, so that it is unnecessary to lift the timber, and when once it is rolled on the table its own weight will keep it in position. The countershafts, belts, &c, as will be seen from the illustration, are placed below the floor, and the bench being fixed on a strong wooden framing, supported by brick or other piers, a chamber is thus formed to receive the sawdust, &c.
