10,174. Schimmel, F. April 30. Single-type composing and casting machines; keyboards; matrices.-A continually rotating and reciprocating cylindrical matrix-block is arrested by the depression of keys with the required character in front of the mould. Simultaneously with the stoppage of the matrixblock, a cam-shaft is started which operates the casting-mechanism. The key-levers 3, Fig. 3, raise obliquely-sliding bars 5 which act on rocking plates 6 and on vertically-sliding bars 7. The plates 6 and the bars 7 release sliding bars carrying pins which arrest the rotary and reciprocating movements of the matrix-block. Five matrix-blocks 28, Fig. 1, are carried by a frame 27 which can be adjusted vertically by means of a screw and a handwheel to bring any block into use. Each matrixblock is provided with a comb 29 by which the mould is adjusted for each character, and can slide without rotation on a shaft to the end of which are secured a pinion 32 and a drum 31. The block is continuously rotated by means of the pinion 32 and is arrested by the entrance of one of the two pins released by a key into one of a series of holes in the drum 31. The block is continuously reciprocated along its shaft by a lever 33 connected to a slide containing a hole which is entered by the second pin released by the key in order to arrest the reciprocating movement of the block. The two movements are transmitted to the block through clutches which are automatically disengaged when the arresting-pins enter their holes. A clutch is simultaneously released which causes the cam-shaft to make one revolution after which the matrix-block is started again. At the end of its revolution, the cam-shaft is stopped in exact position by a lever carrying a roller which enters a recess in a cam on the shaft. The linear position of the block is adjusted exactly by a pointed plunger which enters one of a series of holes in the slide connected to the lever 33. A projection 126, Fig. 16, on the mould enters notches in the matrix-block to adjust the matrices in the vertical direction. Four different sizes of spaces are cast by the operation of special keys which permit the mould to close to different extents. The comb 29 adjusts the mould to the same width for all characters on the same plate of the matrix-block; if the mould is to be independently adjusted for each character, the spacing-washers a, Fig. 28, which separate the matrix-plates m, are provided with parts adjacent to each character which serve to adjust the mould for that character. Moulds; trimming type.-The mould consists of an upper block 89, Figs. 14 and 16, and a lower block 88 both mounted in a carriage 87 which can slide to and from the matrices. The lower mould-block 88 can slide independently on a carriage 92 to remove the cast type from the mould. The upper mould-block is normally held to the left by levers and a cam so as to maintain the mould-cavity 112 at its maximum width, and, when released, is moved to the right by a spring. The width of the mould-cavity for each character is determined by one of the teeth of the comb 29 of the matrix-block which is clamped between projections 113, 114 on the lower and upper mouldblocks respectively. When the mould closes, the upper mould-block is pressed down on the lower one by an eccentric 115, Fig. 16. Passages 87b are provided for water circulation. To enable short spaces to be cast, the upper mouldblock carries a sliding plate 118 which is released and moves across the end of the mould under the action of a spring when a space matrix is presented to the mould. After the type is cast, the lower mould-block moves to the rear carrying the type with it by means of two pins 156<a>, Fig. 16, which project a short distance into the mould. The pins are then advanced to eject the type from the lower mould-block into a composing device in which the line is assembled. At the rear of the mould is a sliding plate 94, Fig. 16, having a conical hole in which the metal-pot nozzle fits. After the type is cast, the plate 94 descends and cuts off the jet of the type. Metal pots and pumps.-The metal-pot comprises a front part 127, Fig. 25, and a rear part 128 connected by a passage 129. The pump 131 is mounted on a shaft 132 about which it can oscillate to a slight extent. The pump piston 133 is operated by a lever 135 and a spring 137 when released by a cam on the cam-shaft 53. The pump nozzle 95 is mounted on a sliding carriage 140 operated by a lever 142 and a cam. When the nozzle is advanced into contact with the mould, a passage in the carriage 140 which communicates with the nozzle is brought into alinement with a passage 131<b> leading from the pump cylinder. Fluidtightness between the carriage 140 and the pump is ensured by the oscillation of the pump which, as the piston descends, is forced against the underside of the slide 140. Galleys and galley mechanism.-The cast types are ejected from the mould into a frame 163, Fig. 24, in which they are retained by detents, the advance of the line being resisted by a spring-pressed plate. The line is prevented from bulging upwards by a plate 182 which is afterwards withdrawn to permit the removal of the line. When a line of types has been assembled, an alarm is sounded and the operator starts a cam-shaft which causes the line to be transferred to the galley. The frame 163 is first moved away from the mould and is then turned about the shaft 167 through a right-angle to bring the line into proximity to the galley Z. The galley slides on a table 187 between two bars one of which is adjustable in accordance with the length of the lines. The type is supported by a block 189 having an angle-plate 190 which can be removed to permit the type to be tied up with string. When the line is raised up to the galley by the frame 163, a rocking member 193 which pushes the lines into the galley is moved away and a plate 200 descends and retains the lines already in the galley. A plate 201 then descends and retains the new line, the frame 163 is rocked back to its normal position, and the line is pushed into the galley by the member 193.
