Abstract: 14,321. Barber, E. B. June 16. The various features described below constitute a keyboard machine for composing and casting type, bonding together the justified type into lines by means of metal strips 304<1>, Fig. 51, flattened out from an original curved trough shape into grooves 304 in the types, and assembling the bonded lines in a galley. The types are formed with inclined recesses 88 for wedge justification. Specification 11,467/07 is referred to. Single-type composing and casting machines; keyboards.-(1) A matrix-plate 42, Fig. 9, is adjusted in two directions for character selection by means of two sets of stops controlled by plunger keys 3 arranged in rows and columns in correspondence with the arrangement of the characters on the matrix-plate. Each key effects the projection of a pivoted vertical stop 30 through a rock-shaft 22 and slide 28 common to the row, and the projection of a sliding horizontal stop through a rockshaft 34, slide 61, drop-bar 138, Fig. 34, and connexions common to the column. The matrixplate 42 is suspended on a shaft 190 mounted in vertical slides 191 and carried by arms 188 of a rock-shaft 187. Elevators 195 connected to the arms 188 are released by a controlling-slide 41 actuated by the slides 28, and fall, assisted by spring action, to effect the descent of the matrix-plate. A stepped stop member 31 for co-operation with the vertical stops 30 is suspended in a slideway from an arm 33 on the rock-shaft 187. For the horizontal movement of the matrix-plate along the shaft 190, the matrix-plate is guided vertically in a carriage 216 propelled horizontally by spring action, which is rendered uniform by variable leverage obtained by connecting the springs to collars sliding along the arms of a rock-shaft. The slide 41 starts a one-revolution cam-shaft 8 effecting the release and return of the carriage 216, the return of the stops, the return of the slide 41, and the ascent of the elevators 195. Springs return the key connexions. The keys 3 are detachably retained in slots in guide-plates 5, 7 by means of adjustable stop - strips 11. (2) The matrix-plate may be provided with two or more founts, and accordingly the stop-member 31, Fig. 9, is provided with two or more sets of stops, and the rock-shaft 190 is carried by shift-slides 179 adjusted by a hand-crank. The working height of the elevators is also correspondingly varied by the provision of two or more shoulders 198 for co-operation with the cam-operated lifting-mechanism, which includes lifting-dogs retracted in their rest position so that the shift - movement is not obstructed. (3) The matrix - plate is centred and locked against the mould by means of a conical-ended pin 240, Fig. 31, projected by means of a cam on the shaft 8 and retracted by a spring 243, the matrix - plate carriage - guides having the necessary lateral play. The matrix-plate is withdrawn from the mould by means of a tubular stripper 241 keyed by a head 82 to the carriage 216 and actuated through a lever 253 from a cam on the shaft 8. The stripper surrounds the pin 240 and is fitted with an adjustable nut 245 forming a stop for a collar 244 to limit the rearward movement of the pin. (4) The types are ejected along guide-rails 504, Fig. 55, past retaining-pawls 804.raised by the ejector, into a line-channel consisting of upper spring-pressed rails 508 holding down the types across lower fixed rails 506. A line-resistant 854 is carried by spring - retained arms 852 pivoted on a slide 707 reciprocated with the justifying-device described below. On the upward movement of the slide 707, a pin 856 engages behind the flange of a bracket 857 to hold the resistant against return to the position for a new line until the pin is raised clear of the bracket. (5) A member 800, Fig. 55, hinged to allow of access to the line-channel, carries the pawls 804, the line-resistant 854, and other parts 710, 811 described below. (6) Wedge spacers 399, Fig. 55, are supplied from a magazine 400 by the action of a space-key 2, Fig. 9. The spacers are notched for engagement by cylindrical yielding rails revolving to reduce wear, and are slotted longitudinally so that they remain on a guide-rail, along which they are finally returned to the magazine by a plate 654 connected to a lever 651 on a spring-tensioned rock-shaft 653 released on the descent of the justifying-device Justifying type; spacers. - (1) The wedge spacers 399, Fig. 55, are bevelled on one face at the upper end for co-operation transversely of the line with the inclined recesses 88, Fig. 51, in the types. The spacers are advanced through and withdrawn from the line by means of a head 487, Figs. 9 and 55, shaped to engage hooked feet 489 of the spacers. (2) Before justification, jaws 710, Fig. 55, sliding vertically, are lowered to determine the length of line. (3) Justification is effected by the depression of a starting-handle located beside the keyboard and connected through a rock-shaft 702, Fig. 9, and linkage 703 to a sliding head 704, Figs. 9 and 55. The justifying-head 487 is spring-supported on a sliding head 705, which is normally disconnected from the head 704, but is raised by the head 704 and becomes connected thereto by a latch 711 for return with the head 704 on reversal of the starting-handle. An upright bar 706 on the head 704 is separably connected to a slide 707 on the hinged member 800. From the slide 707, which carries the line-resistant 854, the end-jaws 710 are actuated through cam-slot and slide connexions. On reversal of the starting-handle, the heads 704, 705 remain connected until the latch 711 is withdrawn by means of a pawl 728 on the rockshaft 653 of the spacer-return lever 651, whereupon the return of the head 704 and starting- handle is completed by spring action. An arm 682 on the rock-shaft 653 trips the clutch mechanism of a one-revolution shaft 925 for subsequent operations described below, and two lock-outs are provided to prevent operation of the starting - handle until the revolution is completed, namely, a shoulder 960 on the latch 711 engaging the pawl arm 961 on the rockshaft 653 to prevent upward movement of the head 705 before the clutch is tripped, and a lock-out dog 962 connected with the handle connexions 703 and adapted to enter a recess 959 in a cam 929 on the shaft 925. A full downstroke of the starting-handle is ensured by the provision on the head 705 of a ratchetmember 720 engaged by a pawl to lock the head 705 against descent until the pawl is tripped by a shoulder on the ratchet-member. Type bar making machines; ejecting typebars; galley mechanism.-From the cam-shaft 925, Figs. 55 and 74, the following parts are actuated:-(1) Line-carriage and preliminary bonding-apparatus. The line of types before withdrawal of the spacers is gripped between upper fixed and lower movable jaws of a linecarriage 907 reciprocated between the assembling and bonding apparatus; in the assembling position the movable jaws are held open against spring action until released by the full-stroke member 720. In the bonding position, the line of types is located under a reciprocating anvil 811 and over a mould 878, described below, in which a bonding-strip has been previously cast. The bonding-strip is forced into the grooves 304, Fig. 51, in the types by means of a hammer 879 forming a section of the mould 878. While the line is held between the hammer 879 and the anvil 811, the movable jaws of the linecarriage are opened, and the line-carriage is returned to the assembling position. (2) Final bonding-apparatus. After the return of the hammer 879, the line is transferred by an ejector 881 across a bridge into a device for completing the insertion of the bonding-strip and alining the types. The device comprises a toggle-actuated table 882 fitted with a sidethrust member 998, and a pivoted anvil member 885 fitted with a yielding top 888, a rigid front plate 886, and a pivoted rear-plate 887 moved inwards to grip and aline the types as the table 882 ascends. (3) Ejecting and galley mechanism. The member 885 is given by rack- and-pinion gearing a quarter turn from the vertical position over the table 882 to a horizontal position opposite a galley 873, in which position the top 888 is advanced to eject the type-bar into the galley. The advance of the top 888 is effected by the engagement of a compound lever 891 for the anvil 811 against links 872 of the top 888; lifters 988 engage, during the return movement of the member 885, under a cross-bar 990 connecting the links 872, to retract the top 888. The galley is reciprocated on ways 969 to and from the member 885. Moulds; trimming type and type-bars. - (1) The type-mould comprises a water-cooled support 275, Figs. 34 and 44, a movable bottom 274, an ejector 313 forming one side, and a water-cooled cap 294 forming the other side and the top. The cap is guided in the support 275 and is closed by springs and raised from the cam-shaft 8 through connexions including linkage 281 and a rock-shaft 284, from which a clamp 298 for the cap is also actuated; a roller 311 engages a serrated surface 312 on the cap to tilt the cap in its vertical movement and so avoid wear on the bottom 274. The support 275 is provided with angular shoulders for centring the bottom 274, which has dovetailed connexion with the ejector 313, so that it moves with the ejector to and from the line-channel; the ejector is actuated from the cam-shaft 8. The set width of the types is determined by the ejector, which is selectively adjusted from the keys; spring-retracted pivoted push-bars 334 on the drop-bars 138 of the horizontal stops are actuated by plungers 336 from levers 338 provided with selective contact-lugs 90 engaged by a cam on the shaft 8, and rock a plate 331 against an arm 329, to set a wedge 328 controlling a spring-pressed lever 321 bearing against shoulders on the ejector; the arm 329 is returned from
