Abstract: 149,273. Wolters, O. Feb. 11, 1919, [Convention date]. Single-type composing and casting machines; strip - perforating machines; keyboards; justifying type. -A device for use in place of a perforated strip for controlling type composing or casting machines or for perforating a record-strip comprises a number of separate holders in which type-characters can be represented by the insertion or displacement of movable elements or control bodies. The holders may be in the form of comb-shaped members f, Fig. 1, the teeth of which are formed with indentations k, Fig. 2, to retain control bodies l, Fig. 3, which cooperate with feeling-levers in the composing or perforating machine. In a modification, U-shaped riders are inserted into grooves in a ribbed plate, and may be supported in an upper position by means of pins. In a further modification, a plate r, Fig. 8, is formed with holes s to receive pins, the upper ends of which project into notches u in the edge of the plate. The insertion, removal, and displacement of the control bodies is effected by hand or by means connected with the keys of a typewriter. The holders representing a line of matter may be locked together. The Specification as open to inspection under Sect. 91 (3) (a) comprises also (1) means for operating type composing and casting machines in which balls or like devices are set up by keymechanism in a partitional frame so as to represent the matter to be composed, the balls then causing the operation of punches to perforate a record-strip or serving to operate the casting-machine directly, and (2) means for operating a casting-machine from a record-strip by means of balls passing through the perforations of the strip. (1) The key-levers 1, Fig. 4 (Cancelled), have each two projections 2, 3 adapted to rock pivoted arms 5, each of which carries a perforated ball-releasing member 6, Fig. 6 (Cancelled), located at the end of a ball-channel 6<a>. When a key is depressed. two balls are released from different channels and fall through tubes 10 into compartments of a partitioned frame 11. The frame is advanced step by step until a line has been composed, when the matter can be corrected. The frame 11 is then in position over an auxiliary frame 12, and a sliding plate separating them is withdrawn to allow the balls to fall into the frame 12 by which they are transferred to a frame 14. The frame 14 is advanced step by step to deliver the balls to a partitioned cylinder 15 rotating within a casing 40, Fig. 5, (Cancelled), the balls thereupon acting through levers 17 on punches 18. The balls return to the machine through a channel 20 which may be closed by a slide 40a to enable the perforated strip to be duplicated. The space occupied by the composed matter is recorded by projections 21, Fig. 7 (Cancelled), of varying size attached to the keys and acting through a bar 22 and ratchet mechanism 23, 24 on a counting-device. In a modification, the keys have projections of varying length adapted to depress a rocking bar. (2) The strip 38, Fig. 10 (Cancelled), passes under a reciprocating slotted plate 43 located beneath two ball-reservoirs 45, 46, the released balls falling down tubes 49 to a partitioned cylinder 50 or a pair of cylinders arranged at an angle. The balls operate members arranged longitudinally and transversely of the keyboard, so that each signal causes the operation of the key located at the intersection of two members. Bars 52, Fig. 13 (Cancelled), extending along each row of keys 53 may have pivoted frames 57 which by the action of the balls of one series are lowered on to the heads of the keys. The balls of the other series cause the depression of bars 60 having fingers 61 adapted to actuate the keys. The record-strip may be divided into two parts travelling under separate ball-holders. This subject-matter does not appear in the Specification as accepted.
