Abstract: 10,471. Roth, J. April 28. Stream-cutting machines; punching and perforating machines.-Relates to automatic tile-cutting machines of the type in which the cutting &c. devices are driven from an independently-driven shaft controlled by a shaft operated by the moving clay stream, and consists in the combination with the controlling-shaft of means for actuating the carriage carrying the cutting-devices, means for periodically releasing the cutter-actuating shaft, and means for controlling a stub cutter. The stream of clay 2, Fig. 1, passes over rollers 7 mounted upon shafts 3 fitted with pulleys 4, Fig. 5, around which passes a band 6 adapted to drive an interchangeable pulley 5 mounted upon the controlling shaft 17. A disk 59, Fig. 1, mounted upon the shaft 17 is fitted with a pin 60 which engages with a rod 61 connected to the carriage 9 and moves it forward, and with a cam 62 which engages with a lever 63, also connected to the carriage 9, and returns it. The pin 60 m a y be adjustably arranged on the disk 59. On the end of the shaft 17 is mounted a cam 18, Fig. 11, which deflects a lever 19 against the action of a spring 24 out of the path of a cam 14 and releases a shaft 11 connected to an independently-driven shaft through a friction coupling 12, Fig. 1. A crank 34, Fig. 3, on the shaft 11 rocks a lever by means of a pin 36 and slot 37, and this lever reciprocates a frame 45 which, by gearing 44, 30, oscillates a frame 33 carrying the cutting- wire 58, for the shaped end of the tile. The wire 58 is attached to pieces 33<b>, 33<c>, sliding radially on arms 33, 33<a> and fitted with rollers 57 engaging with a pattern guide 56, Fig. 1. The straight ends of the tiles are cut by a wire 52<a>, Fig. 4, carried by a frame 52, which is reciprocated by a lever 49 connected to a crank by a rod 46. A roller 66 on the frame 52 raises a lever 67 carrying the stub cutter 67<a>, which is then retained by a lever 68 mounted on a shaft 71. A cam 69, Fig. 3, on the shaft 17 engages a lever 70 carried by the shaft 71 and rocks the latter to deflect the lever 68 when a sufficient length of the rib 2<a> has been cut away. The tiles are also stamped and perforated during the movement of the frame 52 by means of devices carried by a frame 74, which is depressed by a roller 72 against the action of a spring 75. Fig. 6 shows a modification in which the stamping and perforating devices and also the stub cutter are actuated by the sliding frame 45 ; the reciprocation of the frame 45 rocks a shaft 82 which, by means of a pin 84 carried by a lever 83 engaging which a slotted member 86, depresses the stamping and perforating devices 90, and through levers 89, 93 and a link 94 elevates the stub cutter 98, which is retained by a member 99 engaging a catch 100 until, on the return of the carriage 9, the catch is deflected by an adjustable stop 101. In a further modification shown in Fig. 9, the whole of the cutting-devices are actuated by the frame 45, the straight end of the tile being cut by a wire 103 carried by a frame 102 mounted on the shaft 82.
