Abstract: 18,579. Lock, W. H., Pearce, H., and Billington, J. E. Aug. 16. Linotype machines ; stereotype-matrix machines; monotype and like machines.-Relates to machines for composing matrices or type dies for the production of linotypes, lines of type, or stereotype matrices, and more particularly to machines having a number of superposed magazines which co-operate with a single distributor and a single assembler entrance. The bottom magazine rests on a frame 9 containing transverse grooves 18, Fig. 6, which are engaged by bars 19 secured to the underside of the magazine. Gaps in the bars 19 are engaged by blocks adjustably secured in the grooves 18 by means of which the magazine is adjusted laterally. To the top of each magazine are secured transverse bars 23 which are engaged by heels 24 on the underside of the magazine above. To some of the bars 23 ara secured brackets 25 supporting set-screws 26, which bear against the heels 24 of the magazine above and effect its lateral adjustment. All the magazines are held together by bolts 27 which engage the forked ends of the bars 19, 23. Bars 29 secured to the tops of the magazine at right-angles to the bars 23 form a surface on which a magazine may slide when it is removed from the machine. The frame 9 is guided by rods 30 sliding in sockets 31, and is raised and lowered to bring any magazine into use by a lever 44 connected by a rod 47 with a hand-lever 32, which is held in position by a spring locking-rod 34 and a notched quadrant 38. The magazines are balanced by a spring 48, attached at one end to the main frame and at the other to a lever 50 which is connected by links to the frame 9. Exactness of register between each magazine and the magazine entrance 12 and assembler entrance 6 is ensured by blocks 56 secured one to each corner of the frame 9 and containing tapered slots 57. The slots 57 are engaged by studs 64 carried by rocking arms 58, each arm having as many studs as there are magazines in the tier. The arms 58 are pulled into operative position by springs and are moved out of engagement with the magazines by operation of the hand-lever 32. The delivery mouth of a magazine consists of a bar 91, Fig. 7, secured to the top p'ate 92 and an escapement bar formed in three pieces secured to the bottom plate 93. All the escapement levers 101 of a magazine are threaded upon a rod which is supported by the middle member of the escapement bar. Each escapement pawl is connected to its lever by means of a tooth which engages a recess in the lever. The escapement levers are rocked against the force of springs 106 by pushers 109 which are actuated by a set of spring-pressed levers 111 mouritÙ d on the machine frames. The levers 111 are normally retracted against the force of their springs 122 by levers 114 and escapement rods 3 which are under the tension of springs 10. The connexion between each escapement pawl and lever may consist of a ball or disk projecting from the edge or corner of the pawl and engaging a corresponding recess in the lever. The levers 111 may be positively actuated by the rise of the rods 3, in which case a yielding connexion may be interposed to prevent damage in case an escapement pawl should strike one of the lugs of a matrix. The magazine entrance 12 is pivoted to the distributor bracket 5 and is held in operative position by a spring, its position being adjusted by means of a set-screw. The entrance can be rocked back into contact with a shoulder 138 in the event of a matrix jamming. The matrices thus released are guided by a plate 151 fixed to the machine frame into the usual trough 14. The space between adjacent magazines is closed by angle-pieces secured to the top and bottom plates of the magazines. Specifications No. 9570, A.D. 1897, and No. 15,058, A.D. 1904, are referred to.
