Abstract: 11,198. Des Jardins, B. M. May 15. Type, setting.-Relates to type setting and justifying apparatus which may be applied to the machine described in Specification No. 9288, A.D. 1900. Fig. 2 shows apparatus for receiving a line of type from the type-setting machine and transferring it to the re-spacingand justifying apparatus. The types pass along the converging channels 10 to the assembling-point 11, and are forced into an assembling-channel 12 by a packer or star-wheel 13. The channel 12 is mounted on an inclined shaft 14, which can be oscillated, so as to bring the channel either into its horizontal or vertical position, by means of a starting-handle 25 having an arm 28 which acts upon an arm 29 on the shaft 14. A T-shaped block 15, fitted in the channel as usual, carries a pin 17 which slides along a slot in the channel and is connected by a link 19 to an arm 20 mounted on a rock-shaft 21. A spring 22 tends to retain the block 16 in one or other of its extreme positions ; in one of these positions the block is flush with the outer end of the channel, and is ready to support the first type, and in its other extreme position the T-head of the block is opposite a recess 23 in the channel wall into which it passes so as to make way for the traverse of the type. During the movement of the channel 12, disarrangement of the types is prevented by thin plate springs 24. A spring -controlled arm 30, on the bracket 26 carrying the handle 25, serves to push the types into the channel beyond a pair of spring hooks. From the channel 12, in its vertical position, the types are lifted by a vertical slide 36 through an intermediate channel 38 and into a movable justifying-channel 39, Fig. 4 ; the slide 36 has projections 37 which enter the channels. A pair of arms 40, capable of sliding horizontally in a weighted slide 41, rest upon the types as they pass through the channel 38 ; when the s'ide reaches the channel 39, the arms 40 are drawn back by a spring, and the slide is caught and held by a hook 45, while the types enter the channel 39. The slide 41 is released by means of a projection on the slide 36 adapted to rock the hook. The channel 39 is mounted on an inclined shaft 47, as in the machine described in Specification No. 9288, A.D. 1900, and is normally pressed against the channel 38 by a spring 49. A block 50 fitted in the channel 39 is connected by a link 51 to an arm 52 pivoted at 53 and pressed down by means of a spring, one end of which is connected to an adjustable notched plato 54. When the channel 39 is in position over the justifying-apparatus, the block 50 acts as a follower. After the last word has passed out of the channel 39, the block is raised slightly to allow the channel to be moved back to its normal position over the channel 38 ; this is effected by means of a rod 56 which rocks an elbow-lever 57 adapted to push a spring-arm 58 beneath the arm 52. Figs. 7 and 8 show computing- apparatus for determining the final spacing of the line. Three vertical slides71, 72, and 73, of which the slide 71 is set, a= described in Specification No. 9288, A.D. 1900, according to the length of the unjustified line, are fitted within a casing 70. The slide 72 is set according to the number of word spaces in a line by actuating a word-spacing key which is connected indirect to a pawl 79 engaging with rack teeth on the slide73. The slide 72 is actuated by a pawl 82 pivoted to a cross-piece 81 on the slide 73, and this pawl can be moved into or out of engagement with the rack teeth on slide 72 by means of a sliding-plate. When the slide 73 has been raised to a height corresponding to the number of word spaces, the slides 72, 73 are allowed to fall together unlil they are stopped by a pin 88 on the slide 73 striking an abutment. In this way the slide 72 is set according to the number of word spaces, and is then clamped by a pawl 89. The setting for the justification of the line is taken from the slides 71, 72, as described in Specification No. 9288, A.D. 1900. During the justification of the line, the slide 72 is raised to its initial position by means of a pawlwhich is actuated once for each word space. In themachine described in Specification No. 9288, A.D. 1900, the number of movements of the computing-apparatus are effected by a four-motion cam, but in the apparatus shown in Figs. 7 and 8 a reciprocating cam-plate 93 is used instead. In order to prevent the line mechanism from stopping too soon, the rocker arm disengaging the line clutch is held back by an arm bearing against the line cam, which has a part adapted to release the arm at the proper time. The friction-block 101 in the word cut-off channel 102 has a wing 103 with an inclined slot in which travels a pin on an arm. This arm is carried by a disc mounted on a pin 105 and frictionally held between leather washers and discs 107, 108. The disc 109 carries a projection110, which engages with a spring hook 111 as the slide carrying the pin 105 moves to the left. The other parts shown in Fig 5 are arranged and operated in the manner shown in Specification No. 9288, A.D. 1900.
