and this without interfering with the adjustability of the side
cutter-head. Thus uneven wear is avoided. [Illustration: RUSS' MONITOR MOLDING MACHINE.] The bed of the machine is formed with a series of slots or openings provided with bridge bars so that the cutters may act upon the edges of the stuff without danger of injury from striking the bed. The presser shoe is also made adjustable for different thicknesses of the "stuff" and self-yielding to variations in thickness, by a peculiar method of hanging the bar, which carries the presser shoe, to the framework of the machine. The clamp which holds the press block which acts upon the "stuff" after it has passed through the cutter, is of novel construction, and the spindle of the side cutter-heads is so arranged in connection with a loose pulley and the pulley-drums, that both cutter-heads are driven by one belt and in the same direction. The bed plate is provided with springs through which the side cutter-heads are arranged, to move laterally or transversely with a bridge-plate or plates, susceptible of adjustment independent of the cutter-heads, whereby an adjustable support to the "stuff" is given as it passes over the line of the openings in the bed. Most machines have weighted pressure feed, but this having steel springs adjustable by a screw and hand wheel, a heavy or light pressure can be applied according to the work done or size of molding. The cutter-heads are square and slotted so that any style of molding can be stuck by putting cutters on all sides of the head, thus equalizing the cost and |
