Abstract: 29,144. Flemming, Verlag, Buch-und Kunstdruckerei Akt.-Ges., C. Dec. 21, 1911, [Convention date]. Machines for writing in books and the like; web feeding and cutting arrangements; papersupports; alarms. - Account and similar forms printed on a continuous web are filled in by means of a typewriter which is traversed on guides in known manner for line spacing, and one or more carbon copies are taken on continuous webs, which, after each entry, are moved forward a constant distance corresponding to the height of the text, the original account web being simultaneously moved a distance equal to the height of the form. The copy webs are adapted to be bound in book form, means being provided for feeding the copy web, after a predetermined number of entries, a distance in excess of the normal to provide margins for the top and bottom edges of the leaves. The account web 5, fed from a roller 6, passes over a table 4 and is fed by means of a feed roller 7 rotated from a crank-shaft 10. The copy web 12 is fed in the opposite direction by means of feed rollers 13, 14 operated by mitre gears 15, 16 from a shaft 17 driven from the crank-shaft 10 by mitre gears 18, 19. These gears can be changed to vary the relative feeds of the account and copy webs. The excess feeding of the copy web is obtained by means of a hand-operated bar 53 having a pawl 52 which engages pins 54 on the mitre-wheel 15. An automatic bell or other signal device is provided and the excess feed may be actuated by the mechanism which operates the signal. In this case a pawl 57 is lifted by one of the pins 58 on the mitre-wheel 15 and operates the signal. Simultaneously a draw-bar is actuated to withdraw a stop out of a notch in the bar 53, which then moves under the action of a spring. The table 4 is supported by means of projections 33 which rest on cams on the cross shafts 32, 34. The filled-in account forms are detached from the web by means of a pivoted knife carried in a guiding-piece 43 and operated by a cord, the ends of which are connected to a spring drum and a winding-drum at opposite sides of the machine. The knife is drawn to the right by geating connected with the crank-shaft 10 and is then released, the spring drum causing the knife to be shot to the left. The knife is arranged so that it is inoperative during its motion to the right. Carriage-returning mechanism.-The typewriter is returned to its starting point after each entry by means of a cam 37 on the feed-roller 7, which operates a spring-controlled sliding rod 38 having a finger 39 which engages with a projection on the typewriter. The rod 38 may be telescopic so that the starting position can be varied. Ink-ribbon mechanism.-A carbon web 21 is fed from a drum 23 to a winding-on shaft 25 operated by a pawl 26 on one end of a lever 27, the other end of which is engaged by a tappet 29 on a crossshaft 32 driven from the shaft 17 by mitre-wheels 30, 31. When more than one copy web is used, the carbon webs may be arranged at right-angles to the account and copy webs.
