Abstract: 24,377. General Composing Co., and Degener, H. Nov. 4. Linotype machines. -Relates to machines of the kind described in Specifications No. 17,135, A.D. 1893, No. 27,630, A.D. 1897, No. 2181, A.D. 1899, No.9357,A.D.1900, No. 13,772, A.D. 1903, No. 18,766, A.D. 1905, and No. 24,064, A.D. 1906, and more particularly to means for enabling mix e d lines to be composed in characters of two different styles. (1) Assembling- mechanism. Two groups of matrixbars are employed, and are distinguished by the location of a book a, Fig. 3, on opposite sides of the bar. The matrix-bars of each group are distinguished by the shape of the part b which is cut away to a varying extent. The bars are suspended in the magazine by means of apertures c. The spacers, Fig. 5, consist of two flat springs riveted together at their lower ends and separated by a sliding wedge. The magazine is of the usual form, but is provided with separate sets of channels for the two groups of matrices. The levers 65, Fig. 15<a>, which liberate the matrix-releasing slides l are in two groups, either of which can be moved out of operation by means of a hand-lever 104. The key-levers 101 actuate, through sliding bars 102, one lever 65 of each group and one of the stop-bars which arrest the descent of the matrices. The matrix-accelerating levers are actuated by the releasing-slides l against the tension of springs. The slides l, when released, are drawn back by springs into engagement with a bar carried by a rock-shaft 77, Fig. 16, whereby an arm 83 is caused to throw in the clutch of a cam-shaft 84. A cam 89 thereupon rocks the oscillator 91 and returns the slide l. Eccentrically-pivoted arms 92 ensure that only the released slide is engaged by the oscillator. The released matrix is arrested by a shoe carrying a spring pawl which engages the lowest notch in the edge of the matrix. The shoe is then drawn down until arrested by a projected stop-bar. In another form, several spring pawls are fixed at different heights, but only one is .allowed to engage the matrix, the others being withdrawn by the projected stop-bar. Some or all of the magazine partitions may have extensions serving as guides for the falling matrices, the extensions being successively pushed out of the path of the matrices by the piston which advances them. Two guide-funnels 126, 127, Fig. 35, may be employed, the partitions being successively withdrawn upon the advance of the piston 130. When matrices are being delivered to the funnel 126 only, the stroke of the piston 130 may be shortened and the lower part of the partition 134 removed and replaced by the piston itself. In order to prevent rebound, two adjacent stop-bars may be projected simultaneously, the lower to a greater extent than the upper. The bars are bevelled on their upper faces and are spring-pressed so that the falling matrix pushes back the upper bar and is detained thereby. The stop-bars may be each formed of two independently-movable parts corresponding to the two groups of matrices, either set of parts being locked out of action when not required. (2) Distributing-mechanism. After the matrices have been brought to the same level, they are pushed on to two pins 1, Fig. 37, which engage the hooks a of the two groups of matrices, the spacers being engaged by a pin 2. The pins 1 are carried by horizontally-sliding plates 3, 4 mounted in a vertically-sliding carriage 14, by which they are raised and moved opposite to two pins 32 along which they are pushed towards separate distributors. The entrances to the magazine channels are closed by a plate having notches of different depths corresponding to the shapes of the parts b of the matrices. The matrices are moved step by step past the channels, into which they are pushed by a series of yielding pushers. (3) Mould and ejecting-mechanism. The mould is carried by a rocking segment by which it is moved into a vertical position for ejection of the type-bar.
