Abstract: 13,345. St. John, R. H. July 24. Linotype and like machines.-Machine for making type-bars, such as are shown in Fig. 16, by forcing a strip of type metal 4 on to a hard metal body 3 and impressing a line of characters upon it. Fig. 5 shows a vertical cross-section of the lower part of the machine, and Figs. 29 and 41 parts of the distributing &c. mechanism. The matrices 5, which are of the form shown in Fig. 14, are released singly from the magazine 60 by finger key &c. mechanism, and fall into a chute 50, by which they are guided to the assembly chamber with their T heads engaging the rails 63. They are packed into the composing - chamber by a revolving star-wheel, which is on a movable shaft and is moved out of the way so that the line of matrices and spaces may be pushed along the rails 63, after the formation of the typebar, to the distributing &c. mechanisms. The hard metal blanks 3 are in a hopper 10, and are fed along the incline 12 by a reciprocating pusher 28. The soft metal strips or blanks 4 are in a hopper 11, and are released singly by an escapement at 16 and fall on to a slide by which they are pushed so that they fall on to a plunger 13 in front of the blank 10. On the rearward movement of toe plunger the blanks fall in front of it, and are pushed by the forward movement into the slot or mould in a block 30 and against the character depressions of the matrices to impress the characters on and form the type-bar. Space bars 7, Fig. 17, are assembled with the matrices, and justification is effected by pushing up the part 67 over the part 66. Small plates 68 spread apart the parts 66, 67 to justify the line. The movable parts of the space bars are pushed up by a serrated head 80 moved by a lever 81, rod 82, and spring plunger 84 when the lever 81 is released by the pivoted dog 91. The matrices are looked edgeways by a slide or plunger 103, which is moved up. to their rear edges before the justification and before the plunger 13 impresses the type-bar on the matrices. The slide 103 is operated by an adjustable link 105 and an arm 104 of the shaft 98. The lever 81 is normally held raised by a lever 88 operated, and released before justification, by an arm 94 on a sliding bar reciprocated by an arm 99 of the shaft 98. This sliding bar also operates to release the hook 90 from the dog 91, and to move a clamping-piece to and from the end of the line of matrices. The parts are set in motion for the formation of each type-bar by operating a line lever which moves a cam so as to release the spring bolt of a clutch which drives a shaft 119 through a revolution, the continuously-rotating part of the clutch being driven by gearing from the driving-shaft 126. A crank-pin 136 on the end of the shaft 119 operates the head or slide 41 of the plunger 13 through the rod 135. A gear 130 drives a wheel having a crank-pin connected by rods to an arm of the shaft 98. The blank-feeding arrangements are operated from a rock shaft 34 operated by a rod connected to the plunger head 13. The mechanism discharging the type-bar from the holder 30 is operated from a shaft 124, and this shaft is started and driven through one revolution by a clutch the spring bolt of which is actuated by a cam moved by a connection with a trip lever actuated by a cam finger on the shaft 119. The matrices are pressed away from the formed type-bar in the hotter 30 bv a push-bar 360 operated by a cam 362. The holder 30, which is mounted to slide vertically, is moved down with the type-bar therein by a cam 157 on a shaft 156 geared by wheels 154, 155 to a shaft geared to the shaft 124. The type-bar is ejected between trimming-knives 161 into a chute 162 by an ejector 160 operated by a toothed segment 355 and returned by an arm 356 actuated by a roller 357 on the gear 353. The line of matrices and spacers is carried along rearwardly for distribution by an arm on a slide having a spline engaging a reversely-threaded screw groove in a shaft, the spline being withdrawn from the groove when the slide returns to position for a fresh line. As the line is moved along the spacers are threaded by the rings on their upper ends, Fig. 17, upon a needle carried by a slide which is moved up by a reverselythreaded screw grooved shaft, to carry the spacers up to their magazine. The needle is tilted or inclined to cause the spacers to slide off it into their magazine. The T heads of the spacers engage on inclined side rails or flanges of the magazine, and the front spacer engages upper and lower stops. The front spacer is lifted to free it from the stops by sliding plates with inclined edges operated from a space key, and the released spacer falls down the guide-chute 50 to the assembly chamber. After the removal of the spacers the line of matrices is carried on to a slide 215, Fig. 41, having flanges on which the T heads of the matrices are engaged. The slide is moved upwardly and downwardly in an oblique direction by an inclined shaft 214 having a reversely-threaded screw groove. The matrices are released and slide off the flanges of the slide 215 into a transfer box 234, which then, owing to the weight of the matrices, tilts into the position shown in dotted lines, and the matrices are discharged into a magazine 245, in which they lie flat one on top of another. The bottom matrix is pushed endways by a sliding pusher, so that it is disengaged from the parts supporting it and falls on to a support or table along which it is carried by fingers on a pair of endless chains 312. The matrices are successively ejected and carried by the chains 312, until they are engaged by a pair of endless chains above them. These chains 305, 306, Fig. 29, carry them along over the distributing-plates 302, their heads engaging a supporting-ledge. The plates 302 have projections or wards corresponding to the distributing-notches 301 in the matrices, so that, when a matrix reaches the position in which the notches correspond to the wards on one of the plates 302, the matrix 5 is released and falls as shown in Fig. 29, its T head engaging on the flanges 54 in the compartment of the magazine 60. Spring feet 335 on the chain 305 ensure the foot of the matrix swinging down when it is released. The magazine 60 is removable bodily from the machine framing. In each of the compartments of the magazine 60 the matrices are detained by side projections 55 at the top and a stop at the bottom having an inclined front face. The front matrix is lifted to clear the stops and pass into the chute 50, by a dog operated by link and lever connections with the corresponding finger key lever. A top stop 57 allows only the front matrix to be raised.
