Abstract: 25,691. Rozßr, C. Dec. 16. Type, setting; linotype and [like machines.- Relates to apparatus tor perforating strips for automatically controlling type or matrix composing machines. Fig. 1 shows a longitudinal section, and Fig. 15 a cross-section, of the apparatus. The key mechanism is the same as that described in Specification No. 25,764, A.D. 1901, and comprises the keys 89 connected to escapement levers 86 cooperating with toothed discs 92. When a depressed key is released, the corresponding disc 92 operates to move an arm 98, pivoted on a lever 97, so that a tooth 100 on the arm comes into the path of a bar 101<11> on arms 101 pivoted at 101<1> and continuously oscillated by a crank shaft 1. Each arm 98 by means of a pin 98' engages and depresses the arms 102 of a lever pivoted on a shaft 6. The other arms 102' of the levers 102 engage and operate sliding bars 54, each of which is provided with one or more projections 54'. Above and at right-angles to the bars 54 is a series of bars 52 carried by pivoted arms 53 and having projections 53<1> held in engagement with a bar 24<11> by springs 52". The bar 24 is carried by arms pivoted at 115" and rocked, at each operation of a key, by a cam 24 on a shaft 23. Slots in the ends of the bars 52 engage pins 52<1> on pawls 107 pivoted at 108. The projections 54<1> on the operated bar 54 engage under the corresponding bars 52, and prevent them from falling, so that these bars hold up the corresponding pawls 107 with their noses 107' projecting up into the path of pins 109 on pawls 110 on a slide 112 reciprocated at each application by a key. The pins 109 and pawls 110 are lifted by the raised pawls 107, and in the forward movement of the slide the raised pawls 110 engage the projections 111<1> of the corresponding sliding punches 111. The punches 111 corresponding with the character of the key depressed are thus moved forward, and perforate the paper strip. The strip is passed through a slot 137, and is fed forward one step at each operation by rollers 29', 114, the latter being operated by ratchet mechanism 27<11>, 28'. The operated punches are returned by a projection of the slide 112. The shaft 6 has two arms 6<1> carrying a bar 7 extending under all the arms 102, so that the shaft 6 is rocked each time a key is depressed. One of the arms 6' has an extension engaging a latch 134 normally engaging a notch in a disc 4 which it holds stationary. The disc 4 is driven through a friction arrangement by gearing from the shaft 1, and, when the latch 134 is lifted at each depression of a key, the disc 4 is freed and makes a complete revolution. The shaft 23 is driven by gearing from the disc 4, and a cam on the shaft 23 operates the ratchet gear 27<11>, 28<1>. Justifying-perforations are made at the end of each line, by an apparatus which is set according to the space occupied by the characters in the line. On a shaft 8 are pivoted a series of levers 57, the upper arms of which rest on the rear ends of the slides 54, and the lower arms of which engage between pins 59 sliding in a bar 58 and spring pins 68. The pins 59 engage the periphery of a cylinder 9<x>. When a slide 54 is projected, it releases the corresponding lever 57, and this lever is permitted to drop by a bar which extends under all the levers 57, and is carried by arms on the shaft 8, the latter being rocked to return the operated levers 57 by a cam 5 on the disc 4. The shaft of the cylinder 9<x> is driven through a complete revolution by gearing from the disc 4. The surface of the cylinder 9x has a series of recesses 61, one for each pin 59, and, when the recess reaches the pin 58 engaged by the released lever 57, the pin is projected into the recess by the spring pin 68. The distance through which the cylinder 9<x> has at this time moved represents the thickness of the character, and is registered on the justifying-device. The cylinder 9x. is inter-. changeable for different fonts &c., and may be mounted in position by blocks 128 sliding in guides 132 and retained in position by bolts 129 operated by arms on a shaft 131. The cylinder 9 is geared to a shaft having a pair of specially-arranged ratchet discs, which are loose on the shaft, but are coupled to it during the part of each movement of the cylinder 9<x> from its position of rest until the pin 59 enters the recess 61. At each operation of a key, a pawl engaging and holding the ratchet discs is lifted by mechanism operated from the rock-shaft 6, whereupon the discs are coupled to and move with their shaft until the pin 59 enters its recess 61, when the pawl is re-engaged to stop the discs by mechanism operated from the shaft 8, which is rocked when the lever 57 is rocked as the pin 59 enters its recess 61. The ratchet discs operate through gearing to set a disc loose on a shaft 15, and a stop on this disc determines the position of a cylinder 42, which is rotated at the end of each line until arrested by the stop on the disc. The cylinder 42 has a series of longitudinal rows of perforations each corresponding to a particular requirement of justification. The row of perforations in the cylinder 42, required to actuate the punches to make the justifying-perforations for the perforated line, is brought into position opposite a set of spring-controlled pins 39 in a bar 38. The bar 38 is moved longitudinally step by step at each space perforation, under the control of escapement mechanism 34, so that the pins 39 are brought opposite different holes in the longitudinal row, according to the number of spaces in the line. Each pin 39, in any of its positions due to the movement of the bar 38, is opposite the head of a slide similar to the slides 54. Each of these slides is operated at the end of each line, on depressing a justifying-key, by cams 51 and spring lever arrangements 47, 48, 49, and each pin 39 opposite a perforation of the cylinder 42 permits its slide to move forward. Each slide is provided with a projection 44', which operates the punching- mechanism in the same manner as the projections 54<1> on the slides 54. The pins 39 in the bar 38 are in two sets, which operate one after the other, so as to make two rows of justifying-perforations in the strip. The mechanism for operating the justifying-arrangements at the end of each line, and for returning the parts to normal position, is fully described in the Specification. For the purpose of simplifying the key mechanism, each key may be utilized to represent three different characters. When one of the shift keys 89'. 89<11> is depressed, it rocks a shaft 103 having an arm which moves the bar 58 carrying the pins 59. A lever connection with the bar 58 moves a slide similar to the slides 54, having a projection such as 51<1>, which is moved into position to operate one of two bars 52 according to which key 89<1>, 89<11> is depressed. The apparatus may be combined with a type-writer as shown in Fig. 1, the levers 97 being connected by rods 97<1> with the type-bars 97<11> of the type-writer.
