Abstract: 11,512. Thompson, W. P., [McClintock, F.]. May 20. Type, setting.- Relates to typejustifying machines such as are described in Specification No. 3486, A.D. 1902. and consists of im - provements in (1) the line holder or carrier, (2) the mechanism for inserting the wedge-shaped space-bars, and (3) the means for inserting the spaces. (1) The line holder c, Figs. 16 and 17, in which the types z and space-bars e are assembled, is made adjustable for different sizes of types by means of the sliding block 5, which is pressed out towards the vertical plate f of the machine frame by springs 7 and is adjustable by screws 10. To prevent thin types from turning, the block 5 is bevelled at 14, at the lower edge of the type space 12. The holder c is of the same general form as before, and is provided with the adjustable block 6, on which is the pivoted plate 8, which engages the rear end of the line. As the types fall into the holder, from the composing-machine, they and the holder are fed forward by the rotating cam 66 on the adjustable shaft 60, Figs. 12 and 13, the holder moving down the upper race way b formed on the plate a between the plate i and the platef, Fig. 17. (2) The space-bars are lifted and fed into the holder, at each operation of the space key, by the mechanism shown in Figs. 12 and 13. The end space-bar is lifted from thepack gathered together at the upper end of the return raceway, by a plate on a slide 101 operated by an arm 105 mounted to turn on the pivot bolt 112. The arm 105 is connected by a spring 118 to the arm 102, which also turns on the pivot 112, and operates the slide 124 by which the lifted space-bar is pushed forward into the line. The arm 102 is rocked by a roller 121 engaging a cam on a sleeve caused to make one revolution by a clutch engaged by the operation of the space key. The clutch consists of a ring on the sleeve having a lug which is moved by a lever, connected with the space key, into engagement with a toothed sleeve rotating with the shaft, and moved out of engagement at the end of a revolution. The cam is so formed that the slide 124 first pushes the space-bar e into the line bolder into the position shown in Fig. 13, and the cam 66 then moves the thin end of the space-bar forward, after which the slide pushes the space-bar further into the line so that its thin end engages the bevel 40 and enters the slot y in the plate f. A plate 148 on the slide 124 prevents the thick end of the space-bar from moving until the slide is retracted, when the spring lever 137 pushes the rear end of the space-bar forward along the track. The raised space-bar is supported, when the slide 101 is moved down, by a spring plate 146. On the end-plate r is a rib 145 carrying a block 144, the space-bar being lifted into the space between the block 144 and the plate r. For guiding the space-bar as it is pushed forward into the line, and at the same time moving any previously-inserted space-bar out of the way, a lever 129 is provided having a knifeedge extension 131, which operates to hold the space-bar against the end-plate r. This lever is pivoted at 130, and is operated, to raise the extension 131 and release the space-bar, by a spring 134 when permitted by an incline 133 on the lever 129 engaging a roller 132 on the arm 102. The slide 124 and arm 102 are moved for insertion of the space-bar, when the cam engaging the roller 121 permits, by a weighted cord 17 passing over suitable pulleys and connected to the slide 124. (3) The means for inserting the permanent spaces, upon the withdrawal of the space-bars e, is shown in Fig. 3. The end 504 of the swinging space rack is finally positioned by the bevelled end of the driver 530 engaging the bevelled ends 520 of the partitions of the space-channels, to place the selected space-channel accurately over the spacebar e about to be removed from the line. After the removal of the space-bar, the driver 530 forces the permanent space down into the line. The driver 530 is operated by a lever 511 pivoted at 513. On the lever 511 is pivoted at 525, a lever 524 having a roller 541 engaging the operating- cam. The arm 526 of the lever 524 is normally held against the stop 540 on the lever 511, so that the levers operate as one lever, by a cord 528 and weight 529. The cord is attached at 527 to the lever 524 and passes over a pulley 515 on the lever 511. This arrangement permits the lever 511 to yield in case of undue obstruction to the movement of the space down into the line. The remainder of the machine described is substantially the same as that described in the Specification referred to above.
