Abstract: 16,708. Pinel, J. July 30. Monotype and like machines; type, setting.- Relates to apparatus for perforating strips for controlling type casting and composing machines such as that described in Specification No. 15,668, A.D. 1902, the strips being justified and perforated so that they may be fed into the casting-machine in the same order as the composition. Fig. 4 shows a sectional side elevation and Fig. 24 a front elevation of the machine. The keyboard comprises forty-three keys 28 pivoted at 29, and each key is made to represent six different types such as capital, small, italic, &c., by the use of a shift lever C. Beneath each key 28 is a rod or detent 32 having two teeth 33, 34 adapted to be engaged, to fully depress and return the rod 28, by teeth on two constantly-rotating discs 36, 37. The rods 28 are connected with, and depress, levers 38 pivoted at 39. The punches 40-51, for perforating the strip, rest upon long transverse plates 52 suspended vertically on pivoted arms 63, and beneath these plates extend the ends 64 of the levers 38. The ends 64 are each provided with a set of movable pins 65, which engage the plates 52, so that the combinations of plates and punches lifted by the different levers 38 may be readily changed. Six only of the plates 52 are normally operated by the levers 38, five others being moved endways by the operation of the lever C so as to bring projections on their lower edges into position to be engaged by the levers 38, whereby other perforations are added to the combinations when the lever C is moved from the normal to one of its other positions. The rods 32 pass through slots in a transverselymovable plate, and each rod is formed with an incline, which moves the plate transversely when a rod is depressed, and, when the plate is so moved, it prevents the depression of any other rod 32 and key-lever 28. The strip is passed over a large fixed cylinder 31 provided with two loose toothed rings 73 serving to feed the strip, and in engagement with a feed-drum operated by ratchet mechanism, actuated at each depression of a key by a connection with a transverse bar 76 engaged by the ends 64 of all the levers 38. The strip passes from a reel round the feed-drum and round the greater part of the circumference of the cylinder 31, after which it may pass direct to the casting-machine, or be re-wound on a reel resting on the supply reel. A type-written impression is made on the strip of the matter represented by the perforations, by a type-wheel 81 rotated to position the characters by a pair of toothed segments 84 operated by a system of links from a pair of universal levers or plates 87 engaged and operated by a series of rods 88, of different lengths, engaged by the levers 38. The type-wheel is drawn down to the strip by connections 89, 90, 91, 92 from the bar 76, and the impression is made by a hammer 96 actuated by a projection on the rod 92. The rod 92 is connected to the shaft of the type-wheel, and carries a locking-latch 93, which engages notches in the wheel. Two rollers ink the types on the wheel. On the end of each of the levers 38 is a series of removable and interchangeable blocks 98 corresponding in width with the width of the characters, and operating to register the thicknesses of the characters and spaces in the line, and to set the justifying-devices. When a lever 38 is depressed, one of the blocks 98 engages between two studs 101, 102 and moves them apart, the studs 101 being mounted on a transverse slide, and those 102 being fixed. The complete set of studs 101, 102 is moved longitudinally under the proper row of blocks by arms 104 on the shaft 103 of the shift lever C. The slide carrying the studs 101 has an arm 105, which engages and moves to the left an arm 106 on a rod 107 engaging a lever. 108, 110 pivoted at 109. A rod 113 is adjustably connected to the arm 110 and to an arm 115 provided with spring-pressed abutments which engage and feed a disc 114 a distance proportionate to the thickness of the characters. A wheel 118 on the shaft 117 of the disc 114, moves the registering and justifying slide A, 121, and this slide is returned at the end of each line, when a lever D is actuated, by a spring drum and wheel 119 gearing with the rack. A space key is provided, which, when depressed, operates a punch 127 representing a certain thickness of space, a pawl lever 29, which raises a rack 130 one step at each depression, and also operates the bar 76. The rack is retained by a pawl. Its upper end is toothed and engages a toothed wheel 132 rotating with a shaft 133 in the slide A. On the end of the shaft 133 is a snail cam 134 having eight steps representing numbers of spaces in a line from one to eight, and this cam is turned to bring the step representing the number of spaces in the line into position to engage an abutment 135 on a slide which, through a train of gear-wheels 136, a rack bar 137, and gear-wheels, operate to raise a slide 139. On an arm 140 of the slide 139, slides a part 141 carrying a roller 142. The justification is effected by varying eight spaces only when there are more than eight in the line. The roller 142 is thus moved up opposite one of a series of eight rows of steps on a sliding block E. In the slide A, 121 is a longitudinally-movable shaft 148 screwed to receive a toothed nut geared to a wheel fixed on the shaft 133. This shaft 148 carries at one end a latch 150, and, at the other end, an arm 153, engaged by a projection 154 on a vertical rod 155 provided with an arm engaging a sliding piece 157 having a bevelled end engaging an incline on a stepped sector 160 fixed on a pivot shaft. The justifying-lever D is moved by the operator when the line is filled, and operates, through toothed segments, an arm 152 on a sleeve 172 and a shaft 175, passing through the sleeve 172. On the shaft 175 is an arm 176 connected by a rod to the sliding stepped block E, whereby the latter is moved and moves the roller 142 and sliding part 141. The latch 150 releases the arm 152 permitting it to be moved by the lever D at the proper time. An incline on the arm 152, through suitable connections, moves the rod 155 downwards, to move the projection 154 beneath the arm 153 and allow the sector 160 to remain where it was when the operator finished composing the line. The same incline on the lever 152 then engages and moves the slide A, 121 to cause this slide to make a complete movement, in order that the snail 134 may always act equally on the spur 135. A projection 174 on the arm 152 then operates a lever 182, the other end 184, Fig. 4, of which forces back the spindle 185 of the wheels 118, 119 so as to disengage the wheel 118 and permit the wheel 119 to return the slide A, 121. The arm 152 also operates to raise the end 64 of the lever 38 to punch a combination in the strip for separating the lines of composition. The lever D, in its further movement, releases the arm 152 and holds it stationary while the shaft 175 and block E are operated. The block E is arrested by the stepped sector 160, and moves the roller 142 &c. in proportion to its movement and to the height of the steps in the row opposite the roller. The part 141 carrying the roller 142 slides vertically on a horizontal slide 201, connected to a pivoted toothed sector in gear with a pinion on a vertical shaft 206 carrying eight star or ratchet-wheels a, b, c, d, e, f, g, h. On the upper end of the shaft 206 is an arm provided with two brushes 207, 208, Fig. 35, moving over six electric contact segments B', C', D<1>, E', F<1>, G<1>. These six contacts form nine overlapping sections, and each section is divided into three parts, upon which the brushes may be stepped, as indicated by the dotted lines and numerals 1 ... 27. Thus the first section in which the brushes engage the contacts B', C<1> contains the parts 1, 2, and 3, the second section in which a brush engages the contact C', contains the three parts 4, 5, and 6, and so on. On tLe slide 141 is an arm carrying a horizontally-movable stop-piece, which is raised opposite one of the ratchet-wheels a, b, c, &c. according to the number of spaces in the line. This stop-piece is also moved horizontally one or more steps by a rack in gear with a wheel on the shaft of a drum 215, having a spiral series of eight steps adapted to be engaged by eight parallel rods moved by tappets or cam-pieces, of different heights, on the slide 141. On the shaft of the drum 215 is also an eight-toothed wheel, which co-operates with a bar operated at each justifying-space perforation, to disengage the stop-piece from the starwheel a, b, or c, &c., and permit the shaft 206 and brushes 207, 208, &c. to return to normal position after the last justifying-perforations are made. The teeth of the star-wheels are cut to different lengths so that they, in some cases, move from one tooth to another in their engagement with the stop-piece, whereby two different combinations representing different sizes of space are punched in the line when necessary for justification. Mounted to move over the strip on the cylinder 31 are a set of justifying-punches and a contact finger, which co-operates with the space perforations. This set of punches, and the electromagnets for operating them, are carried by a frame on a shaft concentric with the cylinder 31, and, when the first space perforation is made in composing the line, this frame is moved along with the strip. When the justifying-lever D is operated, the set of punches returns to normal position over the perforated strip, and is stopped by the contact finger at each space perforation, the proper punches being then operated, according to the position of the brushes 207, 208 on the contacts B<1>, C', D'. &c., to add the perforations to the space perforation necessary to vary the sizes of the spaces cast by the casting-machine. so as to justify the lines, The return of the lever D operates to return the stepped s
