Abstract

3714. Grant, J. C., Legros, L. A., and Maw, T. F. Feb. 15. Justifying and trimming type; spacers ; galleys and galley mechanism. – Relates to machines of the kind described in Specification 1 4 8 3 / 0 1, in which the line is overset to a greater length than the justified line, and the spaces are reduced to the proper thickness by means of a milling- cutter. The justifying- spaces are so formed that they can be carried in the line of types with their lower ends considerably below the bottom of the type to facilitate the operation of the feeler which selects the spaces for removal. The projecting portions of the spaces also actuate a counting-mechanism for recording the number of spaces in the line, and set in operation the extractor-slide which removes the spaces for reduction. An overset-indicator is provided to show the limits between which the composition of the line must be terminated, and the overset is measured and is divided by a compound-lever arrangement among the spaces in the line. The line of types is fed into a type-race 1, shown in plan in Fig. 1, which may receive the types singly from the delivery-shoot of a setting-machine. The types are pushed to the left by a reciprocating plunger, the front end of the line being supported by a finger on a sliding rod which is connected by a cord to a weight. The spaces 50, Fig. 4, are formed with a deep heel nick 51 which engages a rule projecting from the bottom of the type-race so that the types rest at a higher level than the spaces. The spaces may be cut away at one or both sides for the same purpose. The overset-indicator consists of a fixed pointer, which is adjusted to a position corresponding to the end of a justified line, and a movable pointer, which, at each depression of the space-key of the setting-machine, is advanced by ratchet mechanism through a distance equal to the maximum amount removable from a space. The composition of the line must therefore be stopped when the front end of the line is between the two pointers, an alarm sounding when the end of the line passes to the fixed pointer. The line is now moved to the left by a feed-slide operated by hand, and operates in its passage a space-counter comprising starwheels, which are rotated through one tooth by each space. The star-wheels are connected with an escapement which releases step-by-step a spring-pressed rack-bar 62, Fig. 1, connected to a member 64, Fig. 32, carrying a series of stepped bars 65 which form part of the dividing- mechanism. The line is moved to the left until it strikes a measuring-jaw 66, Fig. 1, mounted on a sliding carriage D. The jaw 66 is thereby moved slightly to the left, and the finger which supports the front end of the line is withdrawn, and is pulled back to the right by the weight. The movement of the jaw 66 pushes down a measuring-wedge, whereby a clutch is closed and the measuring-mechanism is started. An adjustable jaw 122 carried by an arm on the carriage D is moved down into the type-race behind the line, and a pinion, which is frictionally held against rotation and is carried by a lever pivoted on the carriage, is raised into gear with a travelling pitch-chain 92. The measuring- wedge is pushed up by a cam, and the line is clamped between the jaws 66, 122, a measuring- slide, which operates the dividing-mechanism, being simultaneously moved by the wedge through a distance depending on the amount by which the line is overset. The measuring- slide rocks a lever 150, Fig. 32, which acts through a slide 153 upon a second lever 155 which adjusts a measuring-surface slide 159, Fig. 1. The slide 153 is carried by a transversely-moving slide 136, the position of which is determined by the stepped bars 65, and therefore varies with the number of spaces in the line. The parts are so arranged that the final position of the slide 159 determines the amount to be removed from each space in order to justify the line. The measuring-slide is locked in position, and the carriage D is released and is moved to the left bv the chain 92 until the first space enters the extractor-slide F. The extractor-slide consists of two flat slides 163, 164 capable of slight relative movement and having between them an opening which forms a continuation of the type-race 1. Between the slides is pivoted a trigger of which the top is engaged. by the lower ends of the spaces. The movement of the trigger sets in action the driving-gear of the extractor-slide which carries the space out of the line and past a milling-cutter 196. The space is meanwhile moved laterally between the parts of the extractor-slide by a pusher into contact with the measuring-surface slide 159 so that it projects from the extractor-slide by the amount which is to be removed by the cutter, after which it is clamped between the two parts of the slide. As the space is removed from the line, it is raised by an inclined ledge so that it is returned to the line at the same level as the types. After the return of the space, the line moves on until arrested by the next space when the operation is repeated. The milling-cutter is detachably secured to a spindle provided with spring-pressed thrustbearings. The cutter may have two distinct sets of teeth, an outer set for roughing-down the space, and an inner set for finishing, and may be in one, two, or more pieces. At the end of its travel, the carriage D is locked in position opposite to a galley 221 into which the line is pushed. The pinion on the carriage is then moved into gear with the lower part of the chain 92 whereby the carriage is returned to initial position. If a line is prevented from entering the galley, the pusher yields and the return of the carriage is prevented. The galley is inclined, to obviate the necessity for guardrules, and may be adjustable in width by means of a movable side-piece 230 and wedges 228 operated by a screw. The lines are supported by a bar which is frictionally locked against one side of the galley by a spring. In a modification of the machine, the measuring-surface bears against the space during its reduction by the milling-cutter. The type-race is made up of two parts, a fixed race 250, Fig. 36, into which the line is fed from the setting-machine, and a movable race 251 which can be moved by a hand-lever 252 into alinement with the fixed race. The movement of the hand-lever also causes the engagement of a clutch which starts the mechanism. The line is embraced between two jaws 276, 277 mounted to slide on a bar carried by the movable race. A cord 264 attached to the jaw 277 passes round a pulley 279 on the jaw 276 and is attached to a winding- drum. The jaws close on the line which then moves to the left, operating in its passage the space-counting gear B. The right-hand jaw is arrested by a stop 286 which is so adjusted that the jaw 277 moves a measuring – finger 292 through a distance equal to the overset. A dividing-mechanism similar to that before described is thereby operated so that a measuring- surface slide 300 is set. The race 251 is then moved back to initial position and the line is moved to the left by the cords 264 until the first space enters the extractor-slide F where it is arrested by a trigger as before, the winding- drum being now frictionally driven. The extractor-slide carries a plunger of which the projecting end strikes a bevelled part of the slide 300 and is thereby caused to push the space out of the slide F by the amount to be removed by the cutter. After all the spaces have been reduced, the line travels on and is pushed into a galley 221. The galley-pusher carries with it the jaw 277 which is mounted to slide. A spring catch retains the end of the line and prevents its return with the jaw.
