Abstract: 236,580. American Sales Bock Co., Ltd., (Assignees of Hagemann, L. F.). Nov. 20, 1923, [Convention date]. Memorandum appliances; carbon papers and the like, arrangement of.-Relates to autographic registers of the type described in Specification 196,291, wherein a feed roller or disc co-operating with a presser roller to form the web-feeding mechanism is provided with a sliding pin which ensures longitudinal register of the printed forms and is normally held in a retracted position against the pressure of a spring, and consists in the provision of separate means for restraining the pin until it is positioned adjacent to the presser roller, when it is automatically released from the restraint, and may be projected or retracted by relative movement between the feed roller and presser roller. The pin 62, Fig. 3, is radially slidable in one of a pair of feed .discs 13 which project through a slot 12 in a writing-plate 8 and co-operate with the presser roller 21 which is pressed downwardly against the discs by spring-pressed sliding bearings 33. The mounting 20 for the roller 21 is hinged to the case 1 at one side 22 and latched at the other by a spring-pressed catch 26 releasable by a press button 30 after release of a key-operated lock. A pin 65 forming a transverse lug on one side of the pin 62 projects through a radial slot in one side of the disc 13 and engages the. interior of a stationary circular cam 64 to hold the pin 62 in the depressed position flush with the disc 13. The portion of the cam adjacent to the roller 21 is provided with a slot 66, Fig. 4, to allow projection of the pin 62 at this point, at which the pin 62 is normally held depressed by downward pressure of the roller 21 but is projected, on raising the latter, to register the webs initially and to lock the shaft 14 carrying the discs 13 and operating- handle 17. Perforations are arranged in the webs 5 to interrupt the feed on coming between the roller 21 and the discs 13, the discs being of greater circumference than the length of the forms, and the feed being re-started by lugs 61 on the discs 13 out of register with the web perforations. Reverse rotation of the shaft 14 is prevented by a pawl 19 and a ratchet-wheel 18, and the forward rotation is limited to a single turn by a hand-released spring-pressed pin 69. The webs 5. Fig. 2, are stored in a'compartment 4 with a hinged door 2, and are fed over a hinged writing- plate 8 supported by lugs 11 and covered by an apertured plate 46 hinged at one side 47 adjacent to a chamber 44 for a roll of transfer or carbon strips 43. The strips 43 pass transversely across the plate 8, are pressed downward by lateral ribs 60 on the plate 46, and are held at their free ends by a hand-released gravity catch 49 on the plate and by lugs 52 on the case 1 engaging apertures in the catch 49. The webs 5 are separated by rods 54 - - 56, Fig. 2, and are tensioned and eased over the sides of the transfer strips by guides 57, 58 co-operating with a spring finger 59 on the underside of the plate 46. The lowest web is folded in a record compartment 7 by a pivoted finger 67, and the remaining webs are torn off against the mounting 20. The edge 39 of the cover 37 of the compartment 7 separates the webs and extends beneath the mounting 20 to prevent access to the compartment 7 without unlocking the mounting 20.
