A manifolding bookkeeping appliance comprises a flat and substantially rigid base 1, a carrier 5 comprising a part of channel section embracing within it one edge of the base 1 as well as a track 2 laid along that edge, the carrier 5 being constructed for the mounting of a first kind of sheet or card 21 and for stepwise movement along the track 2, and fixing means, such as filing posts 15 or 40 and spring clips 17 or 41, disposed in the region of the track or, such as a single spring clip or similar posts 15 and clips 17, along an edge of the base adjoining the edge with the track 2, serving for the stationery mounting of a second kind of sheet or card 16 or 38 on the base 1 in a position allowing a carbon duplicate of writing on the one kind of sheet to be received on the other kind in all positions of stepwise adjustment of the carrier 5. As shown in Figs. 1-3, a second carrier 6 is mounted for stepwise movement on a track 3 on the opposite edge for mounting a third kind of sheet or card 20. Each carrier 5, 6 embraces the base 1 and track 2 and has inturned edges 7 to retain it thereon. A bowed leaf spring 8 is riveted to the inside of the carrier at 9 and has a pipped formation 10 to engage in any one of spaced perforations 4 along the edge of the track members 2 or 3, the formation 10 being backed by a lug 11. Each carrier 5, 6 has upstanding flat posts 12 which may be three in number and two of which may engage slots 23 each side of the cards 21 or one or more of which may engage holes 25 in the cards 21 or 20. Stops 13 may be provided to prevent sliding of the carriers 5, 6 off their tracks 2, 3 to be engaged by the pip formation 10 or by a part 14 of the spring 8. Sheets 16 placed over the filing posts 15 are held in place by the clips 17 pivotally mounted at 18 adjacent each post, the sheets 16 generally comprising summary sheets. The sheets or slips 21 are preferably secured in the form of a pad 19 by a staple 22 and a line of perforations 26 facilitate removal of each slip. The slips 21 may form clearance records, receipts or they may be cheques and in each case appropriate printing 27 is provided and carbon may be printed on the back of the slip in the position to be duplicated, the slips not in use being turned back out of the way. Slots similar to those in cards 45, Fig. 9, may'be provided which fit not only posts 44 but either flat posts 12 or round posts 15. The card 20 may serve as a ledger or permanent record card of a number of slips 21, and the sheets 16 may then be carboned on the back, instead of using loose carbons, and either a shield of plastic inserted below the sheet being used or each sheet may have a shield of blank -paper. The appliance may be put up in a case 30 of leather, plastic or other flexible material secured to the base 1 and overlapping the front to be secured by a press-button fastener 31 on a flap and on a pocket arrangement 32 arranged so as to hold reserve supplies of the slips 19 and cards 20. In suggested modifications of Fig. 1, not shown, the track 3 and carrier 6 are omitted ; the track 3 and carrier 6 are placed along the top edge and posts 15 and clips 17 are provided for all four corners of the sheets 16 ; the track 3 and carrier 6 and posts 15 and clips 17 are omitted, the sheet 16 being positioned against a reinforcing strip on the right hand edge and held by a single clip along the top edge, the base 1 being without a case 30 but having rubber feet as supports. As shown in Fig. 9, the base 1 is wide enough to take sheets 38, 39 side by side each held in position by filing posts 40 and spring clips 41, the slip 21 or pad 19 of slips being as in Fig. 1 mounted, over the sheet 38, on a carrier 5 moving along a track 2 on one side of the base 1. Loose slips 47 may be held in position over the sheet 39 when required. Between the sheets 38, 39, the base 1 is fitted with rollers 42 at top and bottom on which is mounted an endless band 43 fitted with filing posts 44, preferably having the double keyhole shape shown. On some of the posts 44, a ledger or permanent record sheet or card 45 having similar shape holes is mounted for movement with respect to the sheets 38, 39 to receive entries written thereon. In place of the endless band 43, a second carrier and track may be provided centrally for the card 45 or, in addition, a carrier 6 and track 3 may be provided on the right hand edge of the base. Specification 633,147 is referred to.
