Abstract: 27,048. Foyer, M. J. Dec. 10. Copying documents &c.-In a letter - copying machine, the letters are fed over a table 67, Fig. 3, and between pressure rollers 27, 29, between which also passes the paper strip upon which the copies are to be made. The paper strip passes from the delivery roll 18 under a shaft 47, over a guide-shaft 49 carrying two fingers 50 which confine the paper laterally, between two parallel bars 52, 53 carried by arms 51 on the shaft 47 and then between the rollers 34, 29, which act as wringers, and between the copying-rollers 29, 27, after which it is wound upon the receiving-reel 19. The shaft 47 is turned into one or other of two positions by a thumbpiece 48, Fig. 5, at the side of the machine, and is held in position by a spring controlled lever 57 which engages in notches in one of the arms 51. In one position, the arms 51 are depressed so that the paper strip is caused by the bars 52, 53 to pass through a bath. The rollers 27, 29 are carried by a pair of swinging bars 25. The upper roller 27 is carried by fixed bearings, but the spindle of the intermediate roller 29 is carried in elongated slots 28. Half bearings 35 on the upper side of the spindle are pressed downwards by springs 36 which bear against brackets 31 on the side frames. These brackets also carry pins 32 which engage with slots at the lower parts of the bars 25. The upper ends of the bars are mounted on eccentrics 23 which may be partially rotated together by a handle 24. The eccentrics are mounted upon the eccentric shanks 22, Fig. 7, of bolts which pass through the side framing, or the two bolts may be replaced by an eccentric bar extending across the machine. When the handle 24 is in the position shown in Fig. 3, all the rollers are in operative position, but when the handle is moved back towards the table 67, the eccentrics raise the bars 25 and the three rollers are separated. A stop on the bars 25 prevents the handle from being moved back too far. When the handle is in an intermediate position, the copying-rollers are separated, but the wringing-rollers are not, so that the operation of the machine may be interrupted without the water rising into that part of the strip which has passed the rollers. One of the bars 25 carries on the outside a boss which receives a short shaft upon which is mounted a pinion gearing with a wheel on the spindle of the top roller. The pinion is driven by a handle, and the rest of the rollers are frictionally driven by the top one. The receiving-reel 19 is driven by a belt and pulleys from the lower roller 34. The pulley on the receiving-reel may be made tight or loose on the spindle of the reel by a thumb-nut which screws on the end of the spindle, the latter passing through the pulley, and having a shoulder against which the pulley may be forced by the nut. The pulley may thus be loosened when removing the paper from the reel. The delivery roll 18, Fig. 12, is mounted on a spindle 59 by means of two end pieces 60 having cylindrical parts 60<a> which fit into the spool of the roll, and shoulders which bear against the ends of the spool. Holes 61 are provided for the insertion of pin or nail for screwing up the end-pieces. When the paper is cut, an apron 62, Fig. 3, prevents the end from becoming entangled with the wringing-rollers. The letters are received in a tray 65 as they leave the copying- rollers.
