Abstract: 232,800. Wolters, O. May 26, 1924. Strip-perforating machines; justifying type; keyboards; assembling and distributing matrices. -A machine for perforating record-strips or controlling type-bar-making machines is operated by elements e, Fig. 11, resembling the matrices of a type-bar-making machine, and having indentations f or other features, such as ribs or holes in their faces, for operating the punches. The elements are contained in a magazine from which they are released by the operation of keys, and assembled in line, the line being measured and justified by the aid of elements adapted to cause the release of wedge-spacers in the casting- machine. The completed line is raised to the level of a distributing-mechanism, and the elements are acted on, prior to distribution, by a feeling- mechanism, which selects the punches. Assembling-mechanism. The elements are released from the magazine A, Fig. 2, by escapements 6 operated by rods 4 and levers 4a carrying cams 4d, which are adapted to engage with a rotating cylinder 8. The rods 4 are held down against the action of springs by pawl-levers 2, Fig. 2a, which are retracted by the operation of the keylevers a. Capital letters are represented by the addition of an auxiliary element to each element representing a small letter, which is to be capitalized. The auxiliary elements are released from the magazine by the action of an universal bar 115, which can be rocked by means of a shiftkey into the path of arms l on the key-levers a. The elements are assembled in a collector D, Fig. 1, between a star-wheel and an arm 27, Fig. 3, adjustably secured to a sliding plate 12. A bar 15 is moved a step to the right by ratchetmechanism 20 at the depression of certain keys by which auxiliary elements, indicating, for example, the end of a line, are released, that do not occupy any space, in the cast line. The elements are proportional in thickness to the characters they represent, so that they indicate when the line is of justifiable length. Two pointers 16, 17, which co-operate with a scale 14, are advanced step by step to the left at each operation of the space-key, one pointer moving twice the distance of the other. The position of the pointers at the end of the line indicates the number of blank elements, two sizes of which are provided, which must be added to the line to render it justifiable. The blank elements are associated one with each space-representing element, and are inserted in the line by hand. Distributing and punching mechanism. The completed line is transferred by means of a slide 32, Fig. 1, operated by a handle 31, on to an elevator comprising a toothed bar 35, which is supported by a belt 37 passing over a pulley 38 and wound upon a pulley 39. As the line is transferred to the elevator, a bar 131 is rocked. which causes the pulley 39 to be. clutched to the rotating shaft K. The line is thereby raised to the level of the, distributor F, in which position the elevator is supported by a hook 40. A feedslide 45, which is adapted to transfer the line to the distributor, is simultaneously retracted against the action of a spring by a cord wound upon a pulley 54. As the elevator reaches the upper position, it lifts a tod 152 whereby the clutch-mechanism is disengaged, and the feedslide 45 is released. At the end of its movement, the slide 45 retracts the hook 40 and permits the elevator to descend. The elements are raised one by one into engagement with the distributor screws by a slide 62 in known manner. When engaged with the screws, the elements are subjected to the action of feeling-levers 76, Figs. 2 and 4, having pins 80, which co-operate with the indentations in the elements. The lower screws are interrupted to provide room for the feeling- mechanism, and the threads of the upper screws are. provided with portions c having no inclination, so that a delay occurs in the movement of. the elements. The feeling-levers are closed on the elements by spring action controlled by cams. Those levels that co-operate with indentations n the elements move connecting-members 78, Figs. 2 and 7, which are pivotally connected to the punches 95, into the path of a driving-member 81 by which the selected punches are operated. After passing the feeling-mechanism, the elements are distributed in known manner. The elements may be subjected to the action of the feeling-mechanism before they engage the distributor-screws.
