Abstract: 18,033. Junge, C., [Electric Compositor Co.]. July 31. Linotype and like machines.-Fig. 1 represents a front elevation of the machine, and Fig. 17 matrices used therein. The frame consists of a bed-plate 1 hinged to a box 1<a>, and having an upright member 2, 2<a>, in which are fixed the matrix magazines 3, consisting of vertical channels covered by a glass plate. The matrices are supported in the magazine channels by escapements, each of which consists of a pair of sliding pawls connected to a lever having an arm operated by a rod connected by a ballaud-socket joint to the rear end of one of the key levers 5<c>. The upper ends of the rods are movable to the right or left of their normal position, by the operation of a shift key, so that each rod may be moved into position to operate any one of three escapements. The released matrix passes down converging guide - channels 7, and through the mouth 7<a> into an assembling-trough 8. Each matrix drops on to a spring which closes an electric circuit of a magnet A<2>, the armature of which operates a pusher by which the matrix is pushed to the left along the trough 8 past a pair of retaining-pawls. The line of matrices is supported by a detent 10, which is pushed along by it until the line reaches a certain position, when the detent is automatically withdrawn from the trough, and returns to its initial position, where it again enters the trough for the assembly of a fresh line. When the line has sufficient matrices in it, it may be filled out to the full length by spacers added to the end. The line is moved along to the justifying position by a claw,' which may be grasped by the operator's hand, and swung into the trough, and moved to the left. The line may now be justified by inserting the spacers between the matrices, or by other means. The operator then moves a push 12 down into the trough behind the line. This movement of the push releases the claw and also the detent 10, which then return to their normal positions. The push is then moved to the left to push the matrices into the mould, which consists of a cylindrical block having a longitudinal opening for the matrix line and a radial slot. The opening and radial slot extend the whole length of the mould block, and one edge of the slot, which forms the mould cavity, registers with the formative recesses in the matrix line when the line is pushed into the block. The block is mounted in a recess between a fixed and a pivoted clamping-jaw 21, and when it receives the matrices the mould slot is horizontal. When the matrices are in position the mould is rotated by teeth on its periphery engaged by a sliding rack bar, until the slot is in vertical position under the nozzle of a metal pot 31. Means are provided for clamping the matrices in position and releasing them after the cast; and sliding doors for opening and closing the ends of the mould are operated automatically. When the mould has rotated back to its normal position the push moves on to the left, pushing the line of matrices into an elevator 40, and the type-bar, through trimming-knives, into a shoot 57<a> by which it i, delivered into a galley into which the linotype is pushed by an oscillating arm 58<a>. The push 12 is operated by a pinion and rack, the pinion being geared with its shaft at the required times by means of a clutch operated by a magnet. The shaft operating the mould is also put into operation by a clutch operated by a magnet. The metal pot is heated by gas jets, and is provided with flues through it for the passage of the heated products of combustion. The pump by which the metal is injected into the mould is operated by a lever 31<t>, which is struck by the elevator 40 as it falls to its lower position for the reception of a fresh line of matrices. The elevator 40 slides on vertical rods, and is raised by a chain 40<g>, operated by a sprocket-wheel clutched to its shaft at the proper time by the operation of a magnet &c. The line of matrices is raised into line with a distributing-trough 17 along which the matrices are moved towards the mouth 16<a> of the diverging distributing-channels 16, down which the matrices are released singly, and are guided to their proper channels 3. The matrices are of the form shown in Fig. 17, having formative matrix depressions 15<a>, and notches 15<b> in their opposite edges, which are engaged by ribs in the troughs &c., through which the matrices are moved in the operations of the machine. Each matrix is provided with a combination of one or several holes 15<c> in different positions, which holes permit the passage of contact-pins in a block at the mouth 16<a> of the distributing-channels. The upper portions of the matrices through which the holes 15<c> are formed are all of the same thickness. The contact-pins which do not pass through the holes 15<c>, but engage the side of the matrix, close circuits including electromagnets which operate pivoted switches 16<b> by which the released matrix is guided to its proper magazine channel. Means are provided for maintaining the magnets, which operate the switches, in circuit until the released matrix has had time to pass down into its magazine channel. Means are also provided for clamping the other matrices during the release of the end one. The distributing contact-block is moved to the right to release the end matrix. The matrices are moved along towards the contact block by an arm on a propeller 18 moving on guide-rods 18<a> and moved by a chain 18<b> on wheels 18<c>, 18<d>. The propeller chain is operated by a sliding rack 19 engaging a pinion on the shaft of the chain-wheel 18<c>. The rack is raised by the elevator to bring the propeller to its left-hand position, and when released the rack falls by gravity. The machine with its electric circuits and the contact-arrangements by which the electromagnets are energized at the required times to carry out the complete cycle of operations are described in detail.
