Abstract: 5212. Wicks, F. March 2. Linotype and like machines.-Relates to a machine for composing and casting logotypes in which the matrices and space-bars forming a line are divided into words by means of pieces of metal called mould-ends, so that the line is cast in separate words. The matrices and space-bars are assembled by suitable mechanism in a raceway, and are divided into words by mould-ends of which a standard number may be used, independently of the number of words. A justifying- vice 4 is then brought forward by means of a lever which at the same time brings a segmental nut into engagement with a screw on a rotating shaft 9. The matrices are thereby carried past the vent 10 of a melting-pot, the shanks 1<b> of the mould-ends 1, Fig. 3<a>, projecting between two plates 2 which form the sides of the mould. The nozzle 11 of the melting-pot is turned by the moving part in order to admit and shut off the metal from the mould. The vice 4 is then disengaged by a cam from the shaft 9 and is returned to its initial position by a weight. The matrices, space-bars, mould-ends, and cast logotypes are now carried forward by an endless chain having tappets which engage the lower ends of the space-bars. The matrices and space-bars are carried up inclined guides from which they depend by their lugs until they encouncer a vertical moving chain having two sets of tappets which engage the matrices and space-bars respectively. These are carried upwards by the chain from which they are then disengaged by springs and returned to separate magazines. The mould-ends are withdrawn from the raceway and are delivered to a carriage 31 by a pawl 30 pivoted to a frame 27 which is reciprocated in guides by an eccentric 28. Each mould-end, as it is delivered to the carriage, deflects a spring 31<a>, Fig. 5, and advances the carriage. When the carriage is full, feet 32 on its underside engage a screw thread on a rotating shaft 33 by which the carriage is advanced until the mould-ends meet a stop 34<a>, Fig. 1. To prevent breakage, the right-hand end of the shaft 33 is frictionally driven though a clutch, and the left-hand end is geared to a reversely-running shaft 45, Fig. 3. The mould-ends are fed from the carriage 31 to the composing-raceway as required, by depressing a key 36, Fig. 1, which causes a pawl 37<a> to rotate a ratchet-wheel 38 through the space of one tooth. A tooth on the opposite side of the wheel advances a bar 39 against the action of a spring 40, and places the first mould-end in position for setting. A further depression of the key 36 rocks a pivoted lever 42 carrying a spring finger 43 which displaces the next mould-end from the carriage. During the removal of the mould-ends, the carriage is advanced step by step by means of the shaft 33 until it reaches the position 44. It is then transferred by a yielding finger 44<a>, carried by a reciprocating frame 27, to the shaft 45 which returns the carriage to the loading-position. The left-hand end of the shaft 45 is provided with a friction-clutch to prevent breakage. A yielding-finger 44<b> on the reciprocating frame 27, Fig. 3, then transfers the carriage to the shaft 33. The cast logotypes are carried forward against a spring-pressed stud 46, Fig. 10, the displacement of which causes a toothed wheel 49 to be moved into gear with a rotating wheel 50. A cam 51 is thereby rotated and depresses the line of logotypes into a galley 47.
