Abstract: 23,360. Sigurdsson, O. V. Oct. 31, 1908, [Convention date]. The features described below constitute a keyboard machine in which single types are successively cast and assembled into lines, each line is made into a solid by a casting process, and the lines are successively delivered to a galley. Single-type composing and casting machines; keyboards; driving-mechanism; matrices; moulds.- The matrices are carried by bars mounted in a rocking drum or support, so as to be movable endways opposite a mould from a normal middle position for character selection. The keys of the left half of the keyboard move a matrix-bar in the opposite direction to the keys of the right half. The Figures illustrate two similar typemaking units, which may be in action at the same time and are operable from a single keyboard. The type-making apparatus is of the general character described in Specifications 10,740/07 and 85/08. The matrix-carrying drum of each unit may contain one or more founts of type, each fount being distributed on several matrix-bars; three founts each comprising three matrix-bars carrying the lower case, upper case, numerals, &c. are shown in the Figures. The matrix-selecting mechanism for the drums 76, 77, Fig. 1, is shown in Fig. 15, the drum 77 being omitted. The keys 1, 1<1> of the left and right halves of the keyboard, other than upper case and numeral, move a matrixbar to left and right respectively of its normal central posit on over the mould. The keys 1 actuate rods 2 wh:ch in turn actuate a universal yoke 4 and pins 5. According to the position of a swing- ing-yoke 6, the pins 5 operate either one of two sets of pins 7, one set only being shown, and a particular stop-pawl 12 is thus moved up into the path of a lug 13 on the lower face of a bar 14 connected to the matrix-bar of the drum. A key 1<1> similarly sets a pawl 12<1>. The yokes 4, 4<1> actuate linkages connected to rods 22, 22', which act upon a T-shaped dog 26 carried by a lever 24 linked to the bar 14, so as to rock the dog into engagement with a lever 25 or 25'. A universal bar 3, operated by all the keys, clutches a double cam 30 to a continuously rotating shaft 29, and so, according to the position of the dog 26, the lever 24 and matrixbar are moved to the left or right, the levers 25, 25' being moved yieldingly in opposite directions by the cams. A cam-actuated latch-bar holds the pawls 12, 12' in either the normal or the lifted position. The yoke 6 is automatically oscillated by means of a spring and a face-cam on a shaft which is intermittently rotated by star-wheels and the cams which move the matrix-bars of the drums. Notches in the face-cam corresponding to the high and low points thereof engage a pawl linked to a lever which co-acts with the univeral bar 3. Except when the yoke is in either of its extreme positions, the lever locks the bar 3 and prevents depression of the keys. The matrixdrums are carried by pairs of arms fast to shafts 76<2>, 77<2>, Fig. 1, which are cam-actuated to move the drums down upon the type-moulds. The matrix-bars 80 are mounted as shown in Fig. 20 for endlong movement in the drums ; lugs 80<1> of varying heights opposite the characters in the bars serve as stops for the closing-slides of the moulds. The inner faces of the matrix-bars have a series of holes, opposite the characters, which register with corresponding holes in the matrix-drums. A cam-actuated pin 81, Fig. 20, can pass into the registering holes and lock a selected matrix in casting-position at each key depression. The matrix-drums are rotated manually for fount change and automatically by the capital and numeral keys for change of case. The capital key withdraws a detent from a stop on the matrixdrum and allows this to rotate under spring action until a second stop engages a detent controlled by the numeral key. The numeral key effects withdrawal of both detents, and allows the matrixdrum to rotate to a third position. Return of the matrix-drum is effected by cam mechanism started by the tripping of a cam rocked into the path of a lug on the matrix-shifting bar 14. The inner end of the matrix-drum is surrounded by a head, which is ribbed to engage in a recess in the matrix-bars, and is out away for the passage of the active matrix-bar and the bar 14, a lug on which engages in the recess in the matrix-bar. Type-bar making machines; justifying type; moulds; ejecting type-bars; galley mechanism.-The types are delivered from the two moulds by swinging arms 98, Fig. 6, to a line-channel 103, across the top of which wedge-spaces 105<2> are inserted on operation of the space-key. The spaces 105<2> are carried on a continuously-travelling band 106 and accumulate against a hollow frame 108, within which is a slide for bringing the foremost space into the path of a plunger 112. A plunger 113 ejects the line of types and spaces into a mould, Figs. 6 and 8, comprising a fixed side and bottom 116, a movable side 116<2> provided with a ribs 116<5> to hold up the type a for the passage of metal underneath, a sliding line-channel gate and sprue plate 118, and an adjustable end stop 117 for determining the length of line. The stop 117 is notched for engagement by a projection on a type-facing head, not shown in Fig. 6, which descends upon the line prior to justification. The stop 117 is carried by a sliding block 122, on which is pivoted a hooked line-extracting arm 123, which is held up by a latch until tripped by the facing-head, so that the hook falls to clamp the line. Justification is effected by a table 126, which is provided with a gripping-latch 127<2> for returning the spaces to the band 106 after the line is cast and the facing-head raised. The side 116<2> of the mould recedes to release the type-bar, which is finally extracted by the arm 123 and transferred to the galley 137 by a pusher 125' actuated from the line-extracting lever 124<1>. Metal pots and pumps.-Fig. 43 shows the metal pot, which is provided with two swinging pumps 96 and nozzles 95 to be raised to the single-type moulds 78, 79, Fig. 6, and a third swinging pump 131 and nozzle 131<1> for the line-mould. The nozzle 131<1>, when raised, is forced against the sprue plate 118 of the line-mould by a cam-faced recess 103' in the underside of the line-channel 103.
