FILE CONTAINER FOR LOOSE-LEAF SHEETS.

Application filed June 11, 1924. Serial No. 719,285.

This invention relates to filing devices for loose leaf sheets, such as are commonly used in the form of a tray or suitable contalner with front and back plate rests for the sheets.

Devices of this sort usually comprise a tray or container with front and back plate rests capable of being inclined, one or both of which rests being capable of operatlon to clamp the sheets when the device is not 1n use, and the fioor of the tray or contamer usually has a roughened surface so that the sheets, as they are moved back and forth from one rest to the other will not slip and 1 3ut when it becomes necessary to clamp the sheets, it frequently happens that a mass of sheets weighing several pounds must be forced along the rough floor, and this has resulted in mutilation of the sheets, constant use of the container causing the bottom edges of the sheets to become ragged and unsightly.

It is the chief object of the present 1nvention to obviate this defect, and also to increase the facility with which a mass of sheets may be shifted from one plate rest to another, especially during the clamping operation.

Referring to the drawings- Figure 1 is a plan View of my improved tra l igure 2 is a section at the line 2-2 of Figure 1,

Figure 3 is a section at the line 33 of Figure 1, and

Figure 4 is a front end view of the tray.

Similar reference numerals denote like parts in the several figures. 'i 1 is any suitable tray or container, 5 the rear plate rest and 8 the front plate rest. 29 are rotary bars journaled in the ends of the container in any ordinary manner, cranks 30 being secured to the front journals which extend beyond the front end of the container, a suitable handle 31 having its ends pivoted to these cranks so that the bars may be rotated simultaneously.

Frictional surfaces 32 are provided along the length of the bars upon which the bottom edges of the sheets normally rest, while adjacent these surfaces the bars are perfectly smooth, so that by rotating the bars a quarter turn in either direction, the smooth surfaces will be placed in contact with the lower edges of the sheets, and it will accordingly be noted that both the frictional and smooth surfaces of the floor supports are carried by a single element and are selectively positioned for use by the rotary movements of the bars.

In this construction, the plate rest 5 has rearwardly extending lateral flanged portions which are secured by rivets 34 to the sides of the container, while the front plate rest 8 has forwardly extending lateral wings 35 that fit snugly but freely between the sides of the container, and a set screw 36 is passed through one wing and through an elongated slot 37 in the adjacent side of the container, for the purpose of securing the plate 8 in various clamping adjustments. The loose leaf sheets rest against the plates 5' and 8 and their lower edges are supported on the rough floors 32 when the tray is in use for the usual posting, and it will be clear that the sheets may be manipulated back and forth with no danger of slipping or sagging since their lower edges will always be held in position by the frictional surfaces 32 which constitute rough floors.

WVhen the use of the tray is discontinued, the front plate rest is moved rearwardly and clamped by the set screw 36, so that the sheets will be held firmly between the two plate rests, and if a mass of sheets happens to be resting against the front plate the bars 29 are first rotated in the manner above dey scribed which will cause the sheets to be supported by smooth surfaced floors, so that such sheets will slide easily and freely over these floors during the clamping operation.

While it may not be necessary so to state, still it is deemed advisable to call attention to the fact that the loose leaf sheets occupy substantially the full width of the container, which latter is made in different sizes for different sheets, and therefore it will be evident that the latter are always immediately above the rotary bars 29, so that it will be clear that the rough and smooth floors can be selectively used.

What is claimed is 2- 1. A filing tray for loose sheets, comprising a container, rotary members journaled at the bottom of the container and at the ends thereof and carrying rough and smooth floors a stationary rear support for said A filing tray as in claim 1, further sheets, a slidable front support guided withequipped. with connections between the ro- 10 in the sides of the container, and means for tary members whereby they may be operated securing said front support when it has been simultaneously. I moved rearwardly to clamp the sheets. In testimony whereof I aflix my signature 2. A filing tray as in claim 1, with the adhereto. dition that means is provided for selectively positioning the rough and smooth floors. JOHN SCHADE.
