Abstract: 105,115. Fairweather, H. G. C., (Underwood Typewriter Co.) March 31, 1916 Web feeding and guiding arrangements; inkribbon mechanism.-Relates to web-manifolding arrangements of the kind described in Specification 23349/14, in which carbon sheets interleaved with a longitudinally folded web are connected to a trolly and are fed round the platen with the web and then retracted. (1) Clips for the carbon sheets are secured to stepped blocks 74 on a plate 66, which is detachably secured to the trolly 61. As shown, the plate is provided with dowels 67 fitting apertures in the trolly, and is secured by latches 70 which engage grooves in the dowels. The clips each consist of two fingers 75, 78 secured by a screw 77 to one of the stepped blocks 74, alternate clips being secured to the same block. The fingers are formed with the mating projection and groove 118 to grip the carbon sheet, and the finger 75 is formed with a gauge notch 117 for the side edge of the carbon sheet. To prevent sagging of the clips, the free ends of the fingers 78 are formed with beads 116 which rest on the adjacent clips. (2) The trolly 61 is provided at the corner with ears 63 supporting rollers 64, which run on rails 65 on a frame secured to the platen carriage 14. The frame consists of a crossbar 33 connected by bars 34, 36, 37 tn a tube 35, the rails 65 and brackets 43 for rollers 44 being secured on the bars 36. To reduce shock when the carriage is arrested after free travel for tabulating, cushioning-springs 42 are arranged between the frame 34 and the platen carriage. The tube 35 is secured to a rod which passes freely through lugs 39 on the platen carriage, the springs 42 being arranged between the lugs and the tube. One of the rails 65 carries an adjustable stop 81 for limiting the travel of the trolly, a scale 80 being provided on the rail for setting the stop. The stop consists of a yoke 81 grooved at one side and provided at the other side with a grooved clamp 93 operated by a screw 91, the grooves engaging the edges of the rail. A cam-lever may replace the screw. (3) A guide 56 for squaring the web is adjustably mounted on a bar 55 secured to the paper-table 48, the guide being fitted on one of a number of screws 58 and secured by a nut 59. Tilting of the guide is prevented by ears 60 thereon engaging the top edge of the bar. The plate 66 carries two adjustable web-guides, each consisting of an L-shaped member 94 formed on a plate 96, which is slotted to receive a screw 98 on the block 76. Adjustable web-guides 104, 105 are provided at the rear of the frame 34, the guide 105 being adapted to act as a clamp for preventing movement of the web when the carbon sheets are being interleaved. The guides are secured to sleeves 106, Fig. 2, mounted on a table 102 and provided with locking-pins 108 adapted to enter apertures 107 in the tube. The pins are drawn into the apertures by springs 109 secured at one end to the tube and formed at the other end with a slot engaging a stud 112 for limiting movement. The guide 105 is formed with a finger or clamp 113 which engages the web when the guide is turned downwards. The guide is locked in this position by the engagement of the locking-pin with apertures 114. Web-cutting arrangements.-Pins or cutters 115 sever the web along the perforated longitudinal folds when the trolly 61 is retracted.
