Abstract: 13,772. Scudder, W. S. June 20. Linotype and like machines.-Relates to the matrix-bar accelerating and stopping devices, the line - detaining pawls, the melting- pot and its adjustment, the mould, and the line carriage of the "Monoline" class of composing- machine. (1) Accelerator plates 5, Fig. 1, each impelled by a spring 6 adjusted by a guide-screw 7, are disposed in the lines of delivery of the different matrix bars 8, and corresponding accelerator levers 4, having rounded ends 4<a>, are carried in forks or yokes 3 on the different delivery gates 1. As each matrix bar is released, a stopping- bar and a stop return are simultaneously actuated, and a detent lever connected to the stop return releases a stopping-head 18, which is provided with a buffer plate 21, preferably of raw hide, hard rubber, &c. The matrix bar is provided with a recess 22<a> for engagement with spring pawls 20 on the stopping-head, and a tit is formed in the recess, to spread the pawls. The stopping-head is moved upwards by the action of a spring 19 connected to a lever 26, which is provided with a ball-joint connection 28 with the stem 31 of the stopping-head, and is connected by links 27, 25, 24 to the oscillator 9. To provide against any variation in the timing of the several movements, the detent lever is fitted with a spring- pressed pawl for engagement with the stopping- head on its return movement. (2) The line-detaining pawl 34, Fig. 11, at the front of the matrix bar is lifted out of the way of the incoming matrix bar by means of a releasing plate 40, which is provided with a lug 42 for engagement with a lug 43 on the pawl 34, and is backed by a spring 41, and hinged to a plate 36 operated by a lug 38 on the assembling-box lever. (3) A pressed-steel melting-pot 101, Fig. 21, is used in place of a castiron pot, and the sides and ends are provided with corrugations 102 and corner folds 103, for expansion. The adjustment is effected by means of tapered lugs on the jacket and corresponding wedges adjusted by screws. Supporting lugs are provided at the rear of the pot, and rest in recesses in the jacket frame. (4) The mould slide consists, as usual, of sections 104, 105, Figs. 19 and 21, separated by a block 106 and secured to a block 107 pivoted on the stud 108. The block 106 is provided with slots 111 for engagement with a guide-piece 112 on an upright knee 113, and the stud 108 carries a cam-faced ring 109 provided with a lever 110, so that the slide can be shifted vertically. The mould box 114 is provided with two or more apertures 117, 118 for casting lines, and is moved by means of a link 115 and a lever 116. Trimming-knives 120 and ejector plates 123 are carried by the section 105. (5) The sliding jaw 204, Fig. 27, of the line carriage is loose on the shaft 202, and is dovetailed on a movable plate 205 and secured by screws 207. A justifying- plate 219 is carried at the rear of the carriage, and is dovetailed for engagement with slides 218 operated from the justifying-cam. The plate 205 is retained by a projection 226, Fig. 31, on a shaft 225, which is rocked from a shaft 221 through a lever 222, a detent 223, and an arm 224, to loosen the line, and through a dovetailed plate 227 and an arm 230, to re-set the plate 205. A matrix-bar supporting- ledge 231 is provided on the back of the carriage.
