Abstract: 749,232. Filing papers. FURRER-SOHNE AKT.-GES., R. Aug. 13, 1954 [Aug. 27. 1953; June 18, 1954], No. 23607/54. Classes 16 and 146(1) Suspension filing means such as folders, binders, cards having lateral reference elements and recesses in at least one top portion to co-operate with and hang from two or more horizontal rails, are provided with at least two recesses of different configuration, a rear recess adapted to engage a rear rail from a rear edge of the top portion and a front recess adapted to engage a front rail from below with an upper leading edge of the top portion, the recesses being arranged to prevent movement of the filing means in a direction normal to the rails, i.e. vertical, backward or forward direction but allow sliding along the rails. As shown in Figs. 2, 5a; the front recess, in a top portion 1 of a folder 12 and to engage rail 13, comprises an oblique slot 3, of width H slightly greater than the diameter of the rail 13, leading to a circular hole 2 of larger diameter D and leading by a part of width H to a further hole 4 of diameter D. The rear recess to engage rail 14 comprises an oblique slot 9 widening at the rear edge 8 and leading by a part of width H to a circular hole 7 of diameter D, the holes 2 and 7 being a distance A apart corresponding to the distance between the rails 13, 14. The folder or card 12 is engaged with the rails by movement at an angle # to the horizontal in the direction of arrow 15, so that very little space is required between one set of filing means and another set arranged above. As shown in Fig 6a, the slot 3 may be..widened to assist engagement and the slot 9 may be curved so as to lie in the top portion 1 only. The folder 12 or adjacent cards may be opened for inspection by moving the front edges so that the rail 13 is engaged by the holes 4 instead of the holes 2. As shown in Figs. 7, 8, the shape of the slots and holes is slightly different, the holes 4 being dispensed with but the rear holes 7 being enlarged from front to back, the rear folder or card edges being moved to open for inspection so that the rail 14 engages the rear part of the hole 7. For folders 12, each upper edge may be provided with top portions 1, having registering holes, on one upper edge only, the other upper edge being secured by any known fastening means to the other upper edge below the recesses. In a further modification, the back fold is provided with a top portion 1. Index cards may have a portion 1 at top and bottom to allow reversal of the card. As shown in Fig. 5a, the bottom of a folder may have an arched recess 24 to allow documents 25 to be withdrawn more easily. As shown in Fig. 5a the bottom of a folder' for a gramophone record 30 is provided with an insert 31 having an arched supporting edge 32 for the record 30, the insert 31 being secured by rivets 33 to the side walls 26, 27, and the front edge of side 27 having a cut-out 29 for grasping the record. Each side wall 26, 27 is provided with a top portion 1 with recesses. As shown in Fig. 6c, a folder designed for two records 30a, 30b has a central wall 34 provided with a top portion 1, joined to side walls 35, 36 to form pockets having inserts 37, 38 and upper distance pieces 39, 40. Similarly. folders may be constructed to hold more than two records. The top portion 1 may be reinforced by doubling and the doubled portion may be provided with a lining of plastic or metal permanently secured therein, or the top portion 1 may be formed separately for attachment to existing folders or cards, the portion 1 being of plastic, metal or presspahn. As shown, round rails 13, 14 are used, but the rails may have other cross-sections, such as triangular, the holes 2, 4, 7 then being suitably similarly shaped. Tabs. The lateral reference . elements may comprise, as in Fig. 6a, an extension 28 of one side 26 of a folder, on which references are noted, or as in Fig. 5a, an extension 23 of one side of a folder may have a rail 18 with notches 19 on which slides a tab 20, having a bent front edge 22 and projections to engage the front edge of rail 18 and a raised portion 21. Preferably tab 20 is transparent and holds a strip under the marking area 22. The rail 18 may be provided direct on to the front edge 17 of the card or folder 12. As shown in Figs. 7, 11, the front edge of the top portion 30A is provided with a tab, the front part being provided with a double button 32A and two slots 33A, 34A, each of the slots being for engagement by a hole 45 on a tab having a rear part 44 and shorter front part 42 joined by a back part 43 which will engage either the front edge 40A or top edge 41 according to which slot is used. To engage the button 32A, a tab, similar to that shown but with equal sides and no hook, is provided with holes. In a modification, three spaced holes are provided in the top portion, two of which are engaged by buttons on both sides of a tab, the back of the tab engaging either the front or top edges according to which pair of holes are used. The number of holes, buttons and slots and their shape and position may be varied as desired. The tabs themselves may be used for marking or they may be made of transparent material and a similarly shaped tab inserted underneath.
