Abstract: 21,971. Bhisey, S. A. Oct. 12. Type; type, setting.-A type-setting machine provided with type - casting apparatus for replenishing the magazine, and with means for making and supplying compressible spaces, is shown in elevation in Fig. 2. The magazine n is controlled by a keyboard p arranged to slide longitudinally for fount change. Metal strips 146, Fig. 17, disposed in inclined tracks in a frame 144, fall through slots in the magazine chambers from which types are withdrawn, into position to be raised by a cam-actuated frame 160, for the operation of valve-rods 43 of the corresponding moulds. The rods 43 carry heads 42 controlling passages 32 in a block 31 forming a continuation of a forked spout g connected to the metal pump. The spout g is fitted with safety-valves 36 for the return of surplus metal to the pot. The moulds j are carried on the top of a sliding water tank h, and the mould cover-plate is the bottom 74 of a sliding water tank i. The tank i is supplied with water from a tank l by a flexible pipe 102, and the tank h from the tank i by a flexible pipe 103. The tank i is provided on the top with inclined ridges 98 to engage with corresponding inclines under the tank 7, to force the bottom 74 down upon the moulds ; according to the Provisional Specification, the parts are forced together by arms actuated by the pump piston. The tank h is reciprocated by cam-actuated levers 137. The tank i is provided at each side with a curved peg 153 for engagement with a pivoted catch 154, and arms 157 on the tank h are arranged to raise the catches 154 and engage behind the pegs 153. The moulds are formed from L-shaped blocks and are interchangeably fixed on the tank h by a bar to which separate matrices are secured ; or a matrix bar may be used, and may have different founts on two or more faces. In the case of composite types, such as letters with :ndices, algebra symbols, and Oriental characters, the moulds are modified to cast component parts, such as those shown in Figs. 39 and 4U. The plate 74 is provided with pins or ribs 75, which serve to form notches in the types and to facilitate the ejection of the types. A cut-off slide actuated from a frame 50 on the frame 160 is arranged at the front of the block 31, and is provided with projections for register with grooves in the plate 74. The holes in the slide pass through a rib serving te make the notches in the type bases. The plate 74 is formed near the matrix end with a slit controlled by a bar 78 and communicating with a chamber connected to a cam-actuated air pump. The bar 78 carries a rounded bar 80 in position to engage spring depressed, cam-actuated, forked arms 81. The strips 146 are returned by the engagement with lugs 147 of a bar 145 connected to bell-crank levers 150 connected to the tank h. A type receiver 104 partitioned to correspond with the moulds is pivoted on the tank h and actuated by means of pins 110 and cam-actuated slotted levers 111. A counterweighted pivoted catchplate 107 is tilted by means of pins 119 on the tank h. A spring-inclined pivoted wall 141 on the top of the magazine is pressed backwards by the type receiver. A trimming-knife 128 is provided, and is actuated by means of rollers 129 and camactuated levers 131. In order to be able to cast complete set of types, part 236 of the magazine wall is hinged for turning down flush with a tray o, and the tail-piece 258 of the part 236 projects into the magazine when the part 236 is turned down. A comb 240, connectible with the rocking-frame 164 of the part 160, ejects the types upon the part 236, past a retaining-bar 259 having connection 260 with the frame 160. The tray o is subdivided by walls 252 formed into V-shape at the end adjacent to the magazine ; according to the Provisional Specification, wedges may be used to spread out the V-ends. Bars 253, 254 keep the types in alignment. In a modification, shown in Fig. 10, the magazine n is completely cut through just above the tray o, and the types are ejected by a plain pusher 217 working in two stages. The types are first pushed just out of the magazine, and then end pushers come into operation to close up the line before the advance under the bar 259. The compressible spaces are made from strip metal, which is feed from a reel 264, Fig. 2, to corrugating and cutting wheels 230, from which the spaces pass by a channel 266 to one assembling-band q. The reel 264 is on a slide 262, and is moved to or from the wheels 230 by by means of a lever 232, which is pressed backwards against the action of a spring 234 by a cam on the gearing, and is provided with a projection 267 for passage through a slot in the channel 266, controlled by the presence of a space in the channel. In another arrangement, described in the Provisional Specification, the space metal is in the form of ready-cut strips, and the wheels corrugate only. Means for supplying block types when a magazine chamber is exhausted, and also means for bringing into operation a duplicate chamber, are shown in Fig. 21. The ordinary chambers are each provided with a counterweighted pivoted detector 301, which, in the absence of type, projects above a pin 303 on the escapement mechanism. The detector 301 is raised by its pin 303 and, in turn, raises a corresponding pin 298 for the actuation of escapement mechanism 290 of a corresponding block-type chamber. The duplicatechamber mechanism is somewhat similar, the detector 306 being longer and operating a cranked escapement 305. The line-composing mechanism is shown in Figs. 24 and 26. The types drop from the bands q into the composing-groove s down a fixed shoot 270 and a shoot u movable from under the shoot 270 for the introduction of block types, as determined by an alarm and indicator x actuated by the line resistant v. A central slide 281 is reciprocated from the band gearing, from which is also driven the type packer r and a reciprocating line-retaining bolt 287. The shoot u is provided with type-retaining means 335 released by an incline 338, and with type-ejecting means fitted with a pivoted stem 343 and head 344. Provision is made for forming a gap in the line to receive the block types, and comprises beaked plates 350 sliding and turning on bars 347, 348. The plates 350 are tilted upwards by means of a frame 354 adapted to be retained by a pivoted arm 356, and to be depressed, by the head 344 through a loop 363. The farther plate 350 is made higher than the nearer plate, for engagement by the shoot u to form the gap. The shoot u is provided with a projection 361 for sliding back the plates 350. A slide 359 is provided for closing the shoot u when feeding in the block types. The line-ejecting device comprises a catch w connected to an actuating-slide 324, Fig. 2, and pivoted on a slide 316 connected to a spring drum. The line resistant v is connected to a spring drum, and is automatically thrown into and out of action. A reflector 330 is pivoted over the composing- groove. The justifying, galley, and leading mechanisms are shown in Fig. 37. The justifying- groove t is in line with the composing-groove, and is adjustable in length by means of a graduated bar, which is cam-actuated to effect the compression, a block 414 being first advanced behind the line. The line is ejected by a pusher 419 into the galley z, a gate 429 being first raised. The leads 406 are supplied from a box y by a pusher 423. The lead descends in two stages, first upon the pusher 419, and then drawn into the groove t for advance by the pusher 419 ; in the first stage, the pusher 423 rises, and the leads are advanced in the box y by a spring pusher 421. Two forms of starting and stopping device are described, comprising a hand-raised aud cam-returned counterweighted levar, in the one case carrying a gear pinion, and in the other case making and breaking an electric circuit ; a belt-shifting device of similar nature is described in the Provisional Specification.
