Abstract: 23,114. Boult, A. J., [Lanston Monotype Machine Co.]. Dec. 18. Monotype machines; type, setting; type-writers and like machines.-Relates to machines such as those described in Specification No. 22,208, A.D. 1897. Fig. 1 shows a perspective view of the complete machine, Fig. 9 a vertical central section, and Fig. 11 a section through the punching and paperfeeding mechanism. The paper-feed mechanism is mounted on a detachable frame 3, and consists of pin-wheels 7 on a shaft 8, a supply spool 6 and a winding spool 9. The punches 44 are guided by the bar 34, and the die plate 43 is fixed on the cylindrical holder 42 surrounding the shaft 8. The line register comprises a scale 50 and a pointer travelling in the slot 51 and carried by a rack bar having its starting point determined and adjusted by a pin 56 in one of a series of holes 57. An alarm is sounded by a pin on the rack bar when the line approaches completion. The space counter consists of a numbered disc showing through an aperture 83, and the justification indicator comprises a graduated and numbered dial 95 and a radial index arm 96. The arrangement of the keys 140 follows that of the type matrices in the type-casting machine, the vertical or longitudinal rows each representing types of equal thickness, except the right-hand row, which consists of justifying-keys. Each key 140 is secured to a lever 141 pivoted in the framing 1, and the levers of each vertical row or column are not directly one over the other, but are in slightly different planes, one lever overlapping the other. The levers 141 each operate one of a series of vertical bars 144, placed side by side and extending up through the part 2 of the framing. On these bars 144 are projections engaging a series of transverse pivoted bails 146 extending between the bars 144 and the punch bars 46. Each bail 146 engages a projection on one of the punch bars 46, and the projections on the bars 144 are so arranged that each key operates the proper punch or combination of punches. The punch bars 46 all have projections engaging the upper bail 146, which is connected to and actuates the paper-feed escapement. The bail 146 next below the top one operates a bar 46 having no punch, as it is operated by the row of keys which requires no movement of the die case, and this second bail is utilized to control the movements of the justifying - indicator and line scale. The shaft of the bail 146 operated by the space keys is provided with an arm connected by a link with an arm carrying the driving-pawl of the space - counting disc. The shaft 8 is driven by a motor spring 25, and its movement is controlled by a ratchetwheel 14 engaged by escapement dogs 15, 16 on a lever 17 connected to an arm on the shaft of the upper bail 146. The shaft of the winding-spool 9 is also driven by a motor spring. The motor springs act upon a sleeve 24 loose on the shaft 8 and a similar sleeve on the shaft of the spool 9, and these sleeves have ratchet teeth engaging teeth on spring-pressed sleeves 21, 29 rotating with, but sliding on, the shafts. This permits of the re-winding of the springs by gearing connected with the re-setting mechanism. The punch bars 46, representing types of different width, are each provided with a pair of pins engaging and operating a lever 61, having a stop plate 76 by which the movement of the justification and line indicators is controlled. The shaft 58 of the index arm 96 is driven by a motor spring 60, and is provided with a pinion 59 engaging the rack bar carrying the pointer of the line register. On the shaft 58 is also a toothed wheel 63, called the units wheel, by which the movements of the shaft are controlled. A locking-pawl normally engages the wheel 63 to prevent rotation of the shaft 58. A rack mounted to slide in a pivoted arm is adapted to engage the wheel 63 and control its movements. A spring acts upon this rack, the sliding movement of which is limited, according to the width of the type character, by the projected stop 76. The arm is rocked, to move the rack into engagement with the wheel 63 at each operation, by a rod connected to a pivoted bail engaged and operated by all of the levers 61. This rocking of the arm disengages the locking-pawl and frees the wheel 63, so that it may move under the influence of its driving-spring until the rack is stopped by the projected stop 76. The registers and indicators are returned to zero and the various motor springs re-wound by the re-setting mechanism, which also makes the galley perforation at the end of each line. The re-setting lever 108, which is pressed by the operator at the completion of each line, is connected through a spring connection 107 with a rack bar 106 having teeth engaging a pinion 105 on a shaft 100, on which is an arm engaging pins on toothed wheels 102 geared to the sleeves to which the motor springs are attached, the clutch teeth permitting of the re-winding of the springs without reverse rotation of the shafts. On the shaft 100 is a cam 135 operating a lever 47 connected to the galley punch 45. A second set of rack teeth 121 on the bar 106 gears with a pinion attached to a pinion 123 gearing with teeth on a re-setting bar sliding in the part 54 of the framing. This re-setting bar operates a lever which disengages the locking-pawl from the units wheel, and also carries a pivoted pawl to prevent at this time rotation of the units wheel by its spring. The continued movement of the re-setting bar operates the indicator rack, which rotates the shaft 58 and units wheel back to zero position. The re-setting bar also operates to move a cam which disengages the pawls from the space-counting disc, which is thereupon returned, by a light spring, to zero position.
