Abstract: 382,783. Type writters. TENNANT, W. J., 111, Hatton Garden, London.- (United Autographie Register Co. ; 5000, South California Avenue, Chicago, U.S.A.) Nov 28, 1931, No. 33027. [Class 100 (iv).] Carbon-sheet-arrangements web feeding and guiding arrangements.-In arrangements for manifold typing on webs consisting of a series of from, the firstset of forms is typed, the webs are advanced with the carbon sheets until the second set of. forms clears the typing position, the webs are held, the carbon sheets are retracted into register with the second set of forms, and the webs and carbon sheets are retracted to bring the second set of forms into typing position In the apparatus shown in Figs. 1 and 2, a frame C<1> mounted adjustably on the carriage B supports a standard C<2> which extends close to the platen B<1> and carries a sliding clip C<3> for the leading end of the web pack 25. The clip consists of a spring-urged jaw 17a and a handle 16a.and is connected to the tape 20b of a spring drum 20 on the standard. The frame C<1> is provided with a roller 30 and adjustable fingers 29 for guiding the web pack. The webs are interleaved with carbon sheets 31 which may be separate, or folded zig-zag or stitched together at one or both sides. The carbon sheets are wider than the webs and may have the bottom corners 31a cut away to facilitate passing of the carbon sheets around the platen from the front. When the first set of forms has been typed, the clip is pulled down and connected to the leading end of the webs, the webs and carbon sheets are fed forwards until the second set of forms has passed the platen, the carbon sheets are grasped at the edges and moved downwards into register with the second set of forms, the webs and carbon sheets are fed backwards until the second set of forms is in printing position, and the. first set of forms is torn off. A stop 21 arrests the clip and thereby causes the webs to leave the clip. The clip may consist of a spring arm frictionally mounted on the standard, the spring drum being dispensed with. In the .apparatus shown in Fig. 13, the standard 36 is adjustable in inclination, a cross-bar 33 carrying the standard being trunnioned in a frame 32 and secured by nuts 34a. A slide 37, secured in adjusted position by a screw 37b, carries a spring-urged web clip 37c consisting of a bent wire having fingers 37d, 37f passing though slots in the slide. The webs are. engaged also by a wire 38 which is secured at the top to the standard and is retained by a clip 38a. A zigzag web pack may be placed in a travelling container F, Fig. 11, having a shallow rear wall 39b connected to a front wall 39 by ties 42. Adjustable side-guides 44 for the web are mounted on the front wall. The front wall has slots for engaging hooks 40 on the carriage and is provided with rollers F<1> running on a rail F<2> carried by'arms F<3> which are secured to the machine by the screws employed for securing the feet thereof. Web-cutting arrangements.-A tear-off plate 35, Fig. 13, for the webs is mounted on the crossbar 33, a screw and slot connection 35b being provided for lateral adjustment.
