1587. Boult, A. J., [Converse, F. B.]. Jan. 23. Type, setting; linotype and like machines.- Relates to means for automatically justifying lines of types or matrices. Fig. 1 shows an elevation of the machine, Fig. 6 a section on the line C-C, Fig. 23 the space-selecting block, and Fig. 18 the temporary space placed between words as the types are composed. The types and temporary spaces passing down the raceway 1 are assembled by a wiper wheel in a vertical receiving-channel 3 of a rotary carrier 4 having several (as shown, four) channels 3 placed radially thereon. When a line is composed, a line lever 5 is depressed which engages a clutch by which the line shaft 11 is driven through a complete revolution and the carrier 4 is then moved through a quarter revolution by a ratchet 18 &c. bringing the channel and types therein into horizontal position for justification. When in this position, the types are acted upon by a measuring-wedge 20 which presses them and the follower 24 against an adjustable stop screw 25. The wedge is raised by a rack bar 26 in gear with a wheel 27 having a spring 28 which moves the bar and wedge upwardly. The bar 26 and wedge 20 are normally held down by a lever 29, 30, link 31, and cam on the shaft 11. The cam permits the bar and wedge to move up at the required times. On the wedge 20 is a projecting strip 38, which engages under a pin 39 on a block 40 mounted to slide vertically. The block 40 is thus raised with the wedge. The selecting-block 152, shown separately in Fig. 23, is mounted to move transversely on a verticallysliding plate 49, the slot 48 in the plate 49 engaging the yoke 37 of the selecting-block. A link 53 connects the plate 49 to a lever 54 operated by a spring 55 to lift the plate 49 and block 152. A cam 56 permits this lifting movement, so that the block 152 rises just a little later than the wedge 20 and block 40. When the wedge and block 40 stop, a cam piece on the plate 49 comes into engagement with an arm 41, on the block 40, having a part nut 42, and presses this arm outwardly until the nut 42 engages the screw 43. The block 152 and block 40 are thus stopped in a position corresponding to the movement of the wedge, and to the amount of space required to justify the line. The block 152 is made up of stepped strips fixed side by side, each strip being stepped to operate in justifying lines having a certain number of spaces, and the block is moved laterally on the plate 49 to bring the required strip into position to be engaged by a plunger 88 controlling the sizes of space to be inserted. The block is moved laterally by mechanism actuated by the operation of the space key 79 of the machine. This mechanism engages the yoke 37 at the rear of the plate 49. The block 152 shown in Fig. 23 is composed of eight strips, adapted for justifying lines having from one to eight spaces. The bar 26 and wedge return to normal position, leaving the block 152 in its elevated or set position, in which it remains during the justification. The line of types is then moved along into the channel 22 by a finger 93 on a slide 92 movable along a guide-rail 91 and advanced by a cord connected to a strap operated by rollers and partial discs. The line is stopped as the successive spaces come into position opposite a channel 82, through which the required permanent spaces are pushed out of a magazine 81 into the line, the temporary spaces being simultaneously pushed out by the permanent spaces. The line is stopped at each space by a trip 106, the nose 108 of which engages in the recess in the temporary spaces, Fig. 18. The trip 106 is pivoted to an arm 107 pivoted on a stud 104, and this arm operates a clutch arrangement to cause a revolution of the word shaft 120. A cam on this shaft operates the ejector which pushes the space out of the magazine through the passage 82 into the line. The space magazine contains the spaces, in order of their thickness, in channels side by side, the bottom space being ejected from the channel which is opposite the passage 82. The lower end of the magazine is movable so that any of the channels may be brought opposite this passage. This may be effected by pivoting the upper part of the magazine at some distance above the machine. The position of the magazine according to the sizes of spaces required for justification is controlled by levers 85, 86, &c. connecting it with the plunger 88 which engages the selecting-block. The selecting-block is advanced at each substitution of a space by the screw 43 operated by a ratchet 46, 47, pinion 45, and rack bar 131 operated by the cam 130 on the word shaft. After the insertion of the last permanent space, the line is free to be moved on to the galley 84, into which it is pushed by a pusher 143 on the withdrawal of a plate 135 which separates it from the lines already in the galley. The feed-strap of the block 92 being now released, the block is returned to initial position by a weighted cord 137. In this return movement it brings back the follower 24. The space magazine is moved back so as to clear the plunger 88 from the selecting-block, while the latter is set.
