Abstract: 20,006. Haddan, R., [Hine, C. L.]. Oct. 7. Monotype and like machines type.-Fig. 2 showsa sectional elevation of the type casting and composing machine, Fig. 11 the means for transferring the justified line to the galley, and Fig. 28 a compressible softmetal spacer. A number of matrix bars 1 are arranged to slide vertically and independently in a well 6, and each matrix has a series of matrix depressions 2 on its rear edge, and a corresponding series of registering notches 3 in its opposite edge. The key levers 9 are arranged in vertical and horizontal rows, each vertical row corresponding to the matrix characters on one matrix bar. Each matrix bar is held up in normal position by a keeper 8, and each of the latter is operated to release its matrix bar by a releasing-bar 10 operated by all the keys in one vertical row. Pins 12 on the bars 10 are engaged by the key levers. The released matrix bar 1 is stopped with the proper character opposite the mould 33, by one of a series of stops 13 projected into the path of the falling matrix by the key levers, acting through levers 14. There is a mould 33 opposite each matrix bar 1. For casting the spaces there is a blank matrix bar operated by a space key, and the mould is formed to cast the space shown in Fig. 28, having lateral projections 116 so that it may be compressed to justify the line. The metal pot 220 has two compartments, one for type metal and the other for soft space metal. The pump of the soft metal compartment communicates through a duct with the space-casting mould, and the pump of the other compartment communicates through ducts 25, 26 with the type-casting moulds. The moulds are formed by grooves in a plate 33, and by slides 35 movable in grooves 32. The front ends of the slides 35 form the lower sides and rear ends of the moulds, and they are provided with passages 40 for the metal, which register with the openings 34 when the slides are in their forwards casting position. The slides are normally in the retracted position shown, and, when a key is depressed, a pivoted arm 46, engaged by the matrix bar 1, falls and presses down an abutment 43 sliding in a guide 37 forming part of the slide 35. There is an arm 46 for each slide 35. When the abutment 43 of any slide 35 is moved down, it is engaged by one of a series of fingers 48 on a slide 49, and the slide 35 is thereby moved forwards into casting position. When the abutment 43 is raised, the corresponding finger 48 moves under it freely, and the slide 35 remains at rest. During the casting operation, the matrix bar is registered, and pressed against the mould, by a registering-slide 250 which is moved forwards into one of the notches 3 by a cam 255 on a forked arm 54 engaged by a pin 58 on a rod connected to the slide 49. An enlarged notch 203 is made in each matrix bar 1 for the slide 250 to enter when the bars 1 are in normal raised position. The fingers 48 have downward projections which engage shoulders on the slides 35 and return them after the cast is made. The cast type is withdrawn from the mould by the return of the slide 35, a projection 41 ensuring the withdrawal of the type. The metal passages 26 are normally closed by gates 29 operated to open the passages by levers 242 connected by rods 42 to the respective slides 35. The plungers of the pumps are operated by levers 262 connected to caps 63 loosely mounted on rods 64 and having rollers 65 engaging a cam 66 on the shaft A. Springs 67 on the rods 64 operate the plungers when the cam 66 permits. The plunger lever 262 of the space-metal pump is prevented from acting except when the space key is depressed. Cavities 73 for circulation of cooling-liquid are provided above and below the mould cavities for chilling the castings. When the slide 35 is withdrawn, the cast type is pushed laterally into a line raceway. The passages 40 are cleared by pins 85 on a slide 80 operated by a lever 81 and cam projection 84. The matrix is returned, after the cast, by a shoe 70 on an arm 71 operated by a cam 61. Each key, when depressed, operates through a pin 119 on each bar 10 to lift one of a series of arms 118 on a shaft 117 having an arm 120 engaging a stop 122 on a weighted mutilated friction disc 125. The depression of a key releases the disc 125, which then rotates until it engages the constantlydriven friction disc 126 and is thereupon driven through one revolution. A cam 131 on the shaft of the disc operates a rod 133 by which a onerevolution clutch is actuated to cause the shaft A to make one revolution. The slide 49 is operated by a rod 59 connected to a crank-pin 60. The line of types and spaces is collected in a raceway 79, Fig. 11, and is justified by compression by the type pusher against a stop 87. A line key on the keyboard is then depressed, and this moves an abutment on a slide 98, similar to the abutments 43, and the slide 98 is then moved forwards (to the left of Fig. 11) to push the line on to a pivoted platform 90. The platform 90 is swung down into horizontal position to receive the line by the forward movement of the slide 98, and, as the latter returns, the platform is swung up into the position shown, Fig. 11, to transfer the line to the galley. A modification is described, in which each matrix bar is provided with more than one vertical row of characters, each row representing a different fount, and the bars are mounted in a horizontally-sliding carriage which may be moved to bring either of the rows into casting position. By using a separate stopping-slide 13 for each key, two or more types may be cast at each operation, by the simultaneous depression of two or more keys.
