Abstract: 10,740. Sigurdsson, O. V. June 25, 1906, [date applied for under Patents Act, 1901]. Monotype and like machines.-A keyboard type casting and composing machine is provided with several identical casting-units operated in regular sequence as the character keys are fingered ; the space key controls means for making corrugated spaces. In the machine shown in plan in Fig. 2, three casting-units ate provided, each comprising a matrix - bar 56, 57, 58 adjustable in a depressible pivoted guide-bar 59, 60, 61, a two-part mould 100, 101, Fig. 25, adjustable for width of type, a nozzle and injector supplying metal from a pot 18 common to the three units, a trimming-knife 117 for cleaning the foot of the type as the mould is withdrawn, means for opening the mould to discharge the type, and a discharge shoot converging to a common shoot delivering to the assembling-mechanism. The keylevers 3, Fig. 13, complete an electric current at 4 through a spring contact 1, one or other of three plugs u, v, w on a sliding frame 2, and a corresponding electro-magnet, releasing a clutch to start one or other of three shafts e,f, g for one revolution. The sliding frame 2 is adjusted against the action of springs 48 by connexion with a rock-shaft provided with arms co-operating with cams x, y, z on the shaft e, f, g. The matrix-bar action Comprises a spring- drum connexion 67, a connexion 68 to a winding-up drum 71 engaged with a friction disk 81 on a driving-shaft j by means of a cam 82, 83, 84, a detent released by a rod 73, 74, 75, Fig. 13, operated by a universal bar 90 from projections 92 on fingers 80 pivoted on the key-levers 3, and a characterselecting stop 76, 77, 78 on the connexion 68 arrested by the fingers 80. The universal bar 90 is pivoted on the sliding frame 2, and the fingers 80 pass through slots in the frame 2 and a bridgepiece 89; and are adjusted with the frame 2. The matrix-bar guide 59, 60, 61 is pivoted on a rod 62 and supported by a spring, and is depressed against the mould by a spring-actuated bar 93, 94, 95, Figs. 2 and 25, toothed to a line and lock the matrix-bar. The mould is reciprocated from a cam 118,119,120 through a link 129 slotted over a pin 130 on the mould block 98. A bevelled extension 131 of the link 129 co-operates with a rod 132 to control the bar 93, 94, 95. The movement of the mould section 101, Fig. 25, which is closed by springs 102, is controlled by a lever co-operating with a slotted or bevelled extension 109 and connected with a sliding rod arrested by stop collars ; or, as shown in Fig. 27, a lever 164 connected to the section 101 is provided with a bevelled extension 165 co-operating with a fixed stud 166, and an extension 167 cooperating with a spring latch 168. The mould section 101 may be provided with an extra step 169, Fig. 27, so that when the mould is opened, the type is left free on all sides. The width of the mould is determined by a projection 114 on the section 101 and pins 115 on the matrixbar. A projection 116 on the section 100 engages behind the matrix-bar. The metal injector is actuated by a rod 32, 33, 34, Fig. 2, operated by a spring plunger and controlled by a cam 20, 21, 22. The space-making device is shown is Fig. 23. The strip 140 passes between corrugating and cutting rollers 137, 138 and edge trimmers 162, and the space is received in a carrier 151 delivering to a shoot 153. The space-key releases a clutch 154 to start a shaft for one revolution, and from this shaft the space-carrier bar 150 is actuated: by a cam 148, and the gear of the rollers 137, 138 is actuated by pawl-and-ratchet mechanism 142, 145 from a cam 147.
