Abstract: 21,013. Lanston Monotype Corporation, [Lanston Monotype Machine Co.]. Sept. 21. Monotype and like machines.-Relates to machines of the kind described in Specification No. 18,638, A.D. 1899, for perforating record-strips for controlling type-casting, setting, and similar machines in which the dimensioning of the types is controlled by perforations independent of the selecting or centring perforations. The punchbars 1 are in three groups, two representing position, and the third, dimension, and have lugs 6, 7, 8 which enter slots in a vertically -sliding actuating-plate 11. The punchbars are connected with the plate 11 by interponents 13 actuated by the keys. The key-levers 18 are pivoted on rods 19 mounted in a frame 20, which is pivoted at its front edge to the main frame and is supported by ledges 21 or the like. The frame 20 is in two parts of which the upper, carrying the key-levers, may be removed separately. The key-levers engage lugs 23 on sliding- bars 22, each of which is connected with one of each of the three groups of interponents 13. Lugs 25 on the bars 22 actuate levers 30 carrying bars 31 which are engaged by a number of adjacent bars 22. The levers 30 actuate sliding bars 33 which are connected by arms on rock-shafts 34 with the upper group of interponents 13. Lugs 24 on the bars 22 actuate sliding bars 40, which are connected by levers 41, links 42, and levers 43, with the second group of interponents 13. The third or dimensioning series of interponents 13 are pivotally connected to sliding bars 49, which are connected by lugs and rocking-bars 50 to sliding bars 52. Against the ends of the bars 52 abut bars 63 which are actuated by rocking arms 27 pivotally connected to the lower ends of the bars 22. The bars 52 are carried by a detachable frame 55 and are retained in position during insertion or removal by means of notches 57, which are engaged by two rods 58 carried by arms on rock-shafts. The rods 58 are moved apart so as to engage the sides of the notches by a cam shaft 61. The actuating-plate 11 of the punch-bars is raised by pistons 72, Fig. 7, working in air-cylinders 73 which are controlled by a valve 77 on a rod 79. Arms 80 on-shafts 81 are adapted to engage the ends of the rod 79, and are urged towards each other by a spring 82. Arms 83 on the shafts 81 are engaged by latches 84, 85 respectively. A link 86 pivoted to the latch 84 lies in the path of a bar 71 which is actuated by lugs 67 on the bars 63, Fig. 5. The depression of each key thus trips the latch 84 and moves the valve 77 so that air is admitted to the cylinders 73. The valve is moved back and the parts are re-set by a slide 89 actuated by a lever 90, which is connected to the actuating-plate 11. The feed of the paper is effected by the descent of a rod 2, Fig. 1, which is connected to the actuating-plate 11. The feed-movement is delayed until the punches have been withdrawn by means of a yielding coupling 98. Specifications No. 8982, A.D. 1901, and No. 27,278, A.D. 1904, are referred to.
