Abstract: 454,629. Typewriters. COPELANDCHATTERSON CO., Ltd., Cope-Chat Works, Dudbridge, and DAVEY, J., Springfield Cashes Green, both near Stroud, Gloucestershire. April 3, 1935, Nos. 10387 and 33984. [Class 100 (iv)] Carbon - sheet arrangements ; web - guiding arrangements.-In arrangements in which the webs travel over a support attached to the platen-carriage of a typewriter and provided with a bar having hooks for the attachment of carbon sheets, the support consists of a plate which can be secured in a higher or lower position to suit different machines, and is provided at the top with means such as a rolled edge for guiding the webs. In the apparatus shown in Fig. 2, an inclined webguiding plate 15 at the rear of the platencarriage 6 is connected by brackets 16 to a bar 9 carrying rollers 10 which run on a rail 5 secured to a vertically adjustable standard 4 on a baseboard 1. The bar has a flange 14 underlying the rail, and the rollers are adjustable to take up wear. To permit of raising or lowering the bar 9 to suit different kinds of typewriters, the brackets 16 are adjustable and are secured by screws. The plate is connected to the platen-carriage by means of arms 18 having blocks 19 of rubber &c. for engaging the ends of the platen-carriage. The arms are pivoted on bolts 20 passing through slots 21 in the plate, and are formed with curved slots 22 engaging bolts 20<a>, the arrangement permitting the blocks to engage platen-carriages of different sizes. A vertically slidable carboncarrier 27 is provided with studs 29 passing through a guide-slot 28 in the plate 15, and is connected to a chain which passes over a pulley 39 and carries a counterweight 36. A guiderod 41, mounted on the baseboard, passes through the counterweight. The carbon-carrier is provided with studs 32 for receiving holes formed in the projecting ends of strips secured to the top of the carbons. A web-pack is placed in a tray 25 supported by a bracket 26 on the baseboard, and the webs are fed over the rolled top 23 of the plate 15, threaded through the carbons and fed therewith around the platen. The carbon-carrier is provided with adjustable guides 31 for the webs. When a set of forms has been typed, the platen is turned backwards to retract the webs and carbons, and is then turned forwards to advance the webs, the carbons being retained by means of the counterweight 36. In the apparatus shown in Fig. 7, an inclined web-guiding plate 50 having a rolled top 51 and side-cheeks 61 is secured by means of bolts 55, passing through vertical slots, to a bar 54 which is adjustably secured, by means of bolts 58<a> passing through crossed slots, to brackets 59 clamped or clipped to the tabulating-rack 52 or other part of the platen-carriage 6. The plate 50 can be adjusted vertically and can be secured to platen-carriages of different sizes. A plate 65 is formed with lugs 66 which rest in slots 67 in the side cheeks 61, springs 68 being employed to prevent rattle. The webs and carbons pass between the plate 50 and an inclined flange 69 on the plate 65. The carbons are attached to a flap which engages pins on a strip 76 having hooks 77 for engaging pins 70 on the side cheek 61. When a set of forms has been typed, the webs are pulled forwards and the carbons are arrested by the pins 70. Web-cutting arrangeinents.-In the apparatus shown in Fig. 2, a web-tearing strip 43 is adjustably secured to a strip 42 which overlies the webs and is provided with hooks 47 for attachment to the plate 15. In the apparatus shown in Fig. 7, a web-tearing strip 62 is trunnioned in the side-cheeks 61 and is secured in adjusted position by nuts 63.
