Abstract: 433,349. Filing papers. KINGS PATENT AGENCY, Ltd., 146A, Queen Victoria Street, London.-(Straubel, F. L. G. ; 712, South Monroe Avenue, Green Bay, Wisconsin, U.S.A.) Sept. 12, 1934, No. 26159. [Class 146 (i)] A vertical filing-drawer of the kind having a tilting front which can fall forward from a vertical, normally closed position is provided with a compressor which is movably mounted relatively and adjacent to the tilting front so as to operate between the front and the filing space of the drawer, and an immovable abutment surface is provided on the drawer or front which presses against an abutment on the compressor as the front is closed so as to move the compressor positively inwardly away from the front to apply pressure to the drawer contents. The compressor C, Fig. 3, may comprise an inverted U-shaped member having side arms 10 bent as shown, which may be pivoted at 11 to the tilting front B of the drawer; alternatively, the lower ends of the arms may be hinged to the side walls of the drawer, so that the elbow portion is in contact with the front B. In the former construction, an abutment 12 fixed in the drawer is adapted to engage the end of the compressor arms to cause the latter to engage the contents of the drawer as the tilting front is closed. To maintain the front B closed, the latter is provided with side wings 6, to one or both of which is attached a link 16, carrying a link 13, hinged to the drawer and provided with a spring 15, so as to provide a spring over-centre device, which maintains the front in an open or a closed position. In the modification shown in Fig. 6, the compressor C moves pivotally in a triangular slot cut in the side wings 6<a>, carried by the tilting front, and is provided with leaf or coil springs 26 which tend to force the compressor against the front, and may also serve to assist in holding the compressor in its rearwardly inclined position. The compressor, which comprises resilient arms 24 carried by a bar 21, is provided with arms 22 carrying rollers 23 which in the opening and closing movement of the front B engage guides 27, 28 carried by the inside faces of the drawer. The guides 27 are provided with seats 27<a> in which the rollers 23 engage and are held by the leaf or coil springs 26 and by spring 29 when the front is in its closed position, the compressor being forced against the contents of the drawer as the front is closed by the engagement of rollers 23 with guides 27. The spring 29, which is hooked on to a wing of the tilting front and to a side of the drawer, also holds the front closed. A space compressor D is provided, and as shown in Fig. 6 comprises a spring-tensioned hinged plate 33 carried by a support 39 which is cut away to pass over the card-engaging rod 48 and has side projections which slide in recesses formed in the bottom of the drawer. The support 39 has projections 43 which normally engage rack teeth 46 formed in the bottom 45 of the drawer but can be disengaged therefrom by applying force to the plate 33. The rear end of the wall 45 of the drawer is upwardly inclined so that as the compressor D approaches the end of the drawer it becomes less inclined to the vertical, thus effecting an increase in the effective capacity of the drawer. The forward end of the cardguide rod 48 screws into a collar 50 carried by a bracket 51 on the bottom wall 45 of the drawer and the end knob 52 of the rod is provided with a flange 53 registering with the opening 54 in the front so as effectively to fill this but permit its tilting movement. U.S.A. Specification 1,935,582 is referred to.
