Abstract: 14,451. Boult, A. J., [Johnson Typesetter Co.]. June 15. T y p e, setting.-Types a r e selected and justified in two parts of a power-driven machine. They are supplied from vertical grooves in a magazine M, Fig. 2, corresponding upper and lower case type being in adjacent grooves. They are selected one at a time, or two together if their order permits, by the depression of keys. These tilt corresponding levers 14, raising pushers 15, 15<a>, and the rear ends of ejectors 16. The depression of any key raises a bar 4, which by a lever 6 advances a bar 9 to lock all the keys, and also closes a clutch causing a shaft to make one revolution rapidly. A connected shaft 42 then reciprocates a bar 45 between stops, to push forward the raised ejector 16, and so push the lowest type t from the corresponding groove of the magazine under a vertically-movable nick-guide 79. The shaft also reciprocates an endless band, causing fingers to move along guides, and carry the ejected type to the left-hand end of the guideway 65, where a line is assembled. During these operations, if the bar 4 descends it is locked by a lever 51, freed by the advance of the bar 45, thus preventing any key from being operated until the bar 45 has returned to its original position. When capitals are required, a special key, not shown, is depressed, and shifts a slotted guide 25 and the pushers 15" to the ejectors for capitals. While this change is being made, a lever 28 locks down the bar 4 and the keys. After each word, depression of a key 130<a> causes a temporary space to be similarly placed in the line. These spaces are uniform, and longer than the type. When a line has been assembled, it may be drawn forward on a tilting removable support 119 for correction or insertion of unusual type. When the line is complete, a key 92 is depressed, causing the line to be moved backward by nick-guides to a guide way in the justifying-mechanism, which then operates automatically, while a new line may be set. A part of the justifying-mechanism is shown in rear view in Fig. 9. Depression of the key 92, Fig. 2, releases a bar 98, Fig. 9, which drops, and, being geared to the nick-guides, effects the transfer of the line. It also closes a clutch, causing a cam shaft to make a revolution, operating the justifying-mechanism. The line is pressed against an abutment, adjustable for lines of different lengths by a finger on a slide. The actual length of the line is thus measured, and the difference between this and the proper length determines the amount of motion given to a lever 157. In setting the type, each time the space key 130<a>, Fig. 2, is operated, a cam surface on its ejector 16<a>, Fig. 9, causes a lever 133 and pawl to move a rack 131 a step. A lever 156 is moved correspondingly, in accordance with the number of spaces used in the line, and is thus placed under one of several fulcra x for the lever 157. When the key 92 has been operated, the cam shaft causes the lever 156 to raise the selected fulcrum, and the lever 157 turns about this. A series of levers may replace the single lever 157 with the row of fulcra x. The total space in the line is thus divided by the number of spaces to give the proper width for each space ; the rear end of the lever 157 is connected to a gauge 218, and moves this distance. The gauge 218 is then locked by wedges 223, 224 successively descending at its side. The abutment before mentioned is then withdrawn, permitting the line of type to be moved along its supports by a follower propelled by a weighted cord, until the projecting end of a temporary space engages parting-fingers and a trigger lever. The propelling-weight is then supported while the parting-fingers move back the remainder of the line, leaving a gap. A space of the required size is cut from a metal strip T, which is normally held stationary by a clamp, but is then released and fed against the gauge 218, and cut at a definite point by a vertically-reciprocating saw 249. During cutting, the strip T is supported on a movable block, and when cut, the space is pushed off by a moving fork. It is then pushed into the gap in the line by an oscillating arm. The temporary space is raised out of the line into a spring-closed receiver. The line is then moved on, each temporary space causing a stoppage, and the cutting and placing of a space equal to the first one, until the line is complete. Finally, the line is pushed forward over a galley upon a movable support therein, or on previous type, or a lead from a magazine above the galley. This movement may be produced by a handle. On the completion of a line, the temporary space receiver, which is carried by parallel links, moves over the space groove in the magazine, and returns the temporary spaces thereto. The line-propelling follower is returned by a cord and large weight, previously raised, and released on completion of the line. The type magazine has a separate upper part, supported by a bracket pivoted on the lower part, so that the upper part can be turned to place its grooves horizontal to receive type from metal trays. Sliding stops retain the type in the upper part until they are withdrawn by hand. The metal strips from which the spaces are cut are pushed from a magazine by means operated automatically when a weight feeding the strip in use reaches its lowest position. The remainder of the used strip is at the same time ejected, and the weight raised again ; the operation of the justifying-mechanism is automatically stopped during these operations.
