Abstract: 22,995. Boult, A. J., [Bellows, B. F.]. Oct. 25. Linotype &c. machines; type, setting. -Retates to matrix or type justifying mechanism of the kind described in Specification No. 18,032, A.D. 1897, and comprises, especially, means for operating and controlling the movements of the selecting-plate and the various parts of the machine. The space-selecting plate 100, Fig. 21, is mounted on pivoted frame 103, and is moved in two directions at right-angles to bring the proper set of pins under the projections 102 on the escapement levers 101, after which it is raised to operate certain of the levers to release spacers 3 of the required sizes to justify the line. The spacers are contained in six magazines 5, each having a number of channels, for spacers of different sizes, all communicating with a tube 6, Figs. 2, 11, and 21, arranged to swing forward and laterally. Connected to the lower ends of the tubes 6 by ball - and - socket &c. joints are short tubes 7 which are inserted in the line of matrices as it is assembled, and serve as temporary spacers and also as means for inserting the justifying- spacers in the line. A line of matrices 11 with four tubes 7 therein is shown in Fig. 2, which is a front elevation of part of the machine. The matrices as they are composed are delivered by an assembling-spout 2 on to the assembling rail 1, Figs. 2, 9, and 11, along which they are moved by the arm 16 of a constantly-reciprocating packing- slide 15. Fig. 9 is a plan view. The tubes 7 normally rest in a closely-packed rank to the rear of the assembling-rail, and are held against the slide 9, as shown in Fig. 9, by a finger 13 on a slide 14 urged to the left by a spring. The assembling line of matrices and tubes 7 is packed against a detent 18 engaged by a finger 19 on the slide 17 so that it may also be moved to the rear to permit of the justified line being moved on to the left by a push-slide 25. The detent has a projection engaging a groove in the slide 9, by which it is withdrawn. When the space-key of the machine is depressed, it moves a detent 40 to release a pawl on a timing-slide by which the insertion of a tube 7 into the line is effected. The pawl on this timing- slide, when released, engages ratchet teeth on a slide reciprocated by a connection from the packing-slide 15. When the timing-slide has moved a certain distance, during which movement any released matrices will have had time to reach the assembly rail 1, a hook thereon releases a detent from a lever on a horizontal pivot carried by the vertical shaft 63, Fig. 9, on which the arm 66 is fixed. When so released, the lever swings into the path of a cam-incline on the slide 15, by which the shaft 63 is thereupon rocked to cause the arm to push the end tube 7 forward into the line, as shown in Fig. 11. The tube 7 is then moved along the rail 1 by the slide 15, together with the matrices, carrying with it the lower end of the corresponding magazine tube 6. The lever is returned into engagement with its detent by a pin on the slide 15, and the pawl of the timing-slide is disengaged by an arm on the shaft 63. The timing-slide is returned by an arm on the slide 15, and the rock-shaft 63 is turned back to normal position by a cam-projection on the slide 15. As the tube 7 is moved, by the packer slide, along the rail 1, a rear extension 8 of the tube engages the overhanging front edge of the slide 9, as shown in Fig. 11. As soon as a tube 7 is moved into the line, all the remaining tubes are moved to the left by the slide 14. This slide 14 is thus moved to the left a distance equal to the width of a tube after each insertion of a tube into the line. It is provided with an inclined slot which moves a slide 74, Fig. 2, upwards. A horizontal groove 76 in the slide 74 engages a pin on a stepped lever 78 pivoted on a bar 79 carried by the lower ends of two parallel arms 80, one of which is shown in Fig. 2. The other arm 80 is on a rock-shaft having a horizontal arm connected by a link 84 to the stepped wedge 85, Fig. 21, by which the selecting-plate 100 is stopped and positioned in one direction. The stepped lever 78 is in the path of a finger 21 on the detent slide 17, and the finger is adjusted to such a position on the slide that it will come in contact with the lever when the line has reached a justifiable length. Further movement of the slide 17 due to the addition of matrices to the line will cause the finger 21 to move the lever 78 and bar 79, but the addition of another tube 7 causes the lifting of the lever 78, whereby the finger 21 and slide 17 are permitted to move to the left the distance of the thickness of the tube without moving the bar 79. The movements of the bar 79 and consequently of the wedge 85 are in proportion to the space occupied by the matrices only in the line. The tube-packing slide 14 is connected to a lever, also connected to a second vertically-movable wedge by which the plate 100 is stopped and positioned in the other direction. This second wedge is thus moved in accordance with the number of tubes 7 in the line. The escapements operated by the levers 101 may be such as are described in Specification No. 21,468, A.D. 1904. The selecting-plate 100 has series of empirically arranged pins and is substantially the same as that described in Specification No. 6300, A.D. 1903. The plate 100 is provided with a pin 105 on each end, and these pins are engaged by slots in two arms 107 which embrace the ends of the plate. The arms 107 are fixed on a shaft 108 which is longitudinally movable as well as rotatable. A spring at one end of the shaft 108 tends to move it endways, and presses a sleeve on the shaft against the end wedge, so that the shaft may rotate without the sleeve, but the sleeve is prevented from moving longitudinally of the shaft. A second spring tends to rotate the shaft 108 so as to move the plate 100 laterally against the stepped wedge 85. The plate 100 thus moves in one direction at each upward movement of the wedge 85 and in the other direction at each insertion of a tube 7. The frame 103 and plate are moved upwards when the line is composed by a cam 114 on a vertical shaft 115 driven from an aligned shaft 119, Fig. 28, by a onerevolution clutch, each time the line-key is depressed by the operator. The shaft 119 is driven by bevel gears 161, 162 from the driving- shaft 160. After the up-and-down movement of the plate, the shaft 108 is returned to normal position by a cam-arm 128, on the shaft 115, engaging successively with two arms 129, 134, and after the stepped wedges have moved down they are engaged by the shaft and plate at their upper wider ends. When the shaft 115 has nearly completed its revolution, it operates to release the pawl of a timing-slide 43, Fig. 28, similar to the tube-inserting timing-slide previously described. This second timing-slide moves long enough for the released spacers to reach their positions on the assembly rail, and then operates a switch lever 141 to close an electric circuit between the contacts 142, 143, Fig. 28. A magnet 180 is thus energized, and its armature 184 moves a friction clutch 165 into engagement to cause the advance of the line push-slide 25. This slide is connected with a sprocket chain 155 driven by a vertical shaft 150, driven alternately in opposite directions by bevel gearing 151, 163, 164. The gears 163, 164 may be clutched to the shaft 160 by the respective clutches 165, 166. These clutches are operated by levers 167, 168, connected to the armature frames 184, 185 passing, respectively, through the pairs of magnets 180,181 and 182, 183. The clutch lever 141 is operated by the fingers 38, 39 on the timing-slide 43. When the clutch 165 is engaged, the slide 25 is advanced. A pinion 152 frictionally mounted on the shaft 150 operates a rack to move the slide 9 rearwardlv to withdraw the tubes 7 from the line and also withdraw the detent 18. The detent slide is then returned to its initial position and pushes the tubes 7 back past the end of the slide 9. As the front sides of the tubes 7 are open, the justifying-spacers are left in the line. The stepped lever 78 is now returned to normal position, as also is the slide 43, the latter operating the switch lever 141 to break the circuit of the magnet 180. The left end of the push-slide 25 engages the collar 195 on the rod 194, and moves the contact 193, Figs. 2 and 28, from the contactspring 197 to the spring 198, thereby closing the circuit of the magnet 181 and disengaging the clutch 165, and also closing the circuit of the magnet 182 by which the clutch 166 is engaged. The movement of the shaft 150 is thus reversed, the slide 25 returns to the right, the slide 9 is moved to its forward position, and the detent 18 is moved forward over the assembling rail 1. The righthand end of the slide 25 engages a collar 196 on the rod 194 and moves the contact 193 from the spring 198 to the spring 197, thereby breaking the circuits of the magnets 181, 182 and closing the circuit of the magnet 183. This latter circuit is closed because the circuit was also closed at 189, 190 by the switch lever 188 connected to the armature frame 185. As shown in Fig. 11, the lower front portions of the tubes 6 are cut away to enable them to pass the assembling-spout 2. To prevent the spacers from falling out of the tubes, a plate 93 is provided. The lower part 94 of this plate is hinged to permit of access to the line being assembled, and removal of matrices therefrom if desired. When the linekey is depressed, the part 94 is swung down by the armature of a magnet, the circuit of the latter being closed by a contact-disc 92 on the shaft 115 &c.
