Application August 22, 1939, Serial No. 291,358 s `(ci. 457) This invention relates to ling drawers, and particularly to a compression plate disposed at the rear end of the drawer whereby the files contained in the drawer may be readily expanded when the drawer is opened and conversely ccmpressed when the drawer is closed.

In Patent No. 1,887,882, a le drawer is dis.

closed which is provided with a pair of slidable y Vthe cabinet in which the drawer is mounted, the

sliding movement being approximately three inches. This motion first forces the follower plate and the files into a, vertical position and then moves the les bodily along the bottom of the drawer from one and one-half to three inches. The amount of push or force necessary to accomplish the compression and movement of the files in closing the drawer is objectionable to most operators. Furthermore, compression and movement of this character is purely theo-V retical and not practical where speed ling is essential.

'I'he object of the present invention is to generally improve and simplify the construction and operation of filing drawers and the follower or compression plate contained; to provide a compression plate which is hinged at its lower edge to the rear end of the drawer so that compression at the bottom edges of the les is constant; to provide a compression plate the upper end of which is movable only and which is spring actuated to normally compress the upper ends of the les but permitting the operator of the :Gle to expand the contents at the top for the purpose of removal or examination of the contents; to provide an adjustable spring actuating mechanism so that any desired pressure may be applied to the les; and further, to provide a structure which is economical to manufacture and which may be readily installed and applied.

The invention is shown by way of illustration in the accompanying drawings, in which:

Fig. 1 is a perspective view of a le drawer;

Fig. 2 is an enlarged central vertical section of the rear end of the drawer;

Fig. 3 is a cross section taken on line III-III of Fig. 2;

Fig. 4 is a perspective view of a portion of the drawer showing one of the removable spacer plates;

Fig. 5 is a perspective view of one of the removable spacer plates; and

Fig. 6 shows a modified form of the lower end of the compression plate.

Referring to the drawings in detail, and particularly to Figs. 2 and 4, A indicates the front panel of a filing drawer, 2-2 the sides, and 3 the bottom thereof. In the bottom proper and extending centrally and longitudinally is ay depressed channel with side walls in which are formed uniformly spaced slots 5 terminating in enlarged V-shaped notched ends as indicated at 6. The purpose of these combinatlon notches and slots will hereinafter appear.

The upper side edges of the drawer are channeled as indicated at I`I, and these channels form guideways for a pair of sliding bars .8 8 which are connected at the rear ends by a cross rod 9. Forming a closure for the rear end of the drawer is a compression plate I0 which is hinged as at II at its lower edge to the rear bottom portion of the drawer. The ends of the plate I0 are flanged as indicated at I2, and vertically disposed elongated slots I4 are formed in the flanges through which the cross rod 9 extends.

The side bars 8 have a limited sliding movement of from one to three inches, and as they are connected by the cross rod 9 and this extends through the slots I4 formed in the flanges on the follower plate, this plate will swing about its hinges II from the full lineposition shown in Fig. 2 to the dotted line position indicated at Illa. during opening movement of the drawer, and the movement will be reversed during closing. Bumpers I5 on the rear ends of the sliding bars and rollers on the upper edge of the compression plate will engage the frame of the cabinet in which the drawer is mounted and by push action on the part of the operator will force the bars back into the channels .l in which they are mounted.

It is preferable, however, to maintain the side bars in retracted position and the compression plate in a consequently vertical position during normal operation whether the drawer is open or closed. T his is accomplished by employing a pair of compressing springs I1, one on each side of the drawer. These springs are mounted in suitable housings I8 disposed below each of the channels l. A slot I9 is formed in each channel and fastened to each side bar 8, and projecting into each housing I8 is 'a lug 20 which engages with one end of each spring. The opposite end of each spring seats in cups 2| carried by screw rods 22. These have a threaded engagement with the ends of the housings I8 and, by proper adjustment, any degree ofA pressure may be exerted by the springs on the lugs 20 and, through the side bars and the compression plate I8 actuated thereby, sufcient pressure is exerted to normally maintain the upper ends of the illes under balanced compression; but they will at the same time permit the` operator of the file to expand the contents at the top for the purpose of removing or examining the contents.

In Patent No. 1,887,882, previously referred to, the follower plate is hinged approximately twothirds of its height above the bottom. This location of the hinge has the disadvantage of crowding the contents forward at the bottom and in practice forces the contents to lift up off the bottom of the drawer. In other words, in actual operation, the contents are iirst lifted up and later slump down and some les will remain up and some down; hence uniform visibility of the upper edges of the les is not maintained. Obviously if one can employ a follower or compresion plate which is permanently hinged at the bottom of the drawer and at the same time permit expanslon of this plate and the les within the drawer, then forced compression at the bottom is eliminated and the contents will remain in visible alignment without the disadvantage above referred to. In the improved structure disclosed in this application certain of the essential parts of the patent heretofore referred to are employed, to-wit, the sliding bars, and substituting for the movable follower board a compression plate 1ocated at the rear of the drawer and hinged or hooked into the bottom thereof and adding the spring action to this compression plate, the effect of which will be to automatically restore to a balanced vertical position the compression plate, the spacer plates, and the file contents whenever they have been spread apart. The spring action furthermore eliminates the necessity of forced compression during the closing of the drawer. At the same time the springs may be so adjusted to the weight of the contents of the drawer that the operator of the file can readily expand the contents at the top for the purpose of removing or examining the contents.

If it is desired to subdivide the contents of a drawer, spacer plates such as shown at B (see Figs. 1, 4 and 5) may be employed. These plates have a bottom plate 30 riveted or otherwise secured thereto, on the lower and outer edges of which are formed laterally extending lugs 3|. Lateral lugs 32 are similarly formed at the upper end of the spacer plates B so that they will normally rest on top of the channels 1 and assume an inclined position. To change the position of the spacing plates it is only necessary for the operator to grasp them by their upper edges and to swing them to a vertical position, when the plates B, together with the lugs 3l, may be lifted vertically out of the notches and slots 5. 'I'he plate may then be moved longitudinally to any desired position and while still held vertically is dropped in to the notches 5 and then released to tilt either forwardly or rearwardly. In the tilted position, the plates B are locked against removal, as the lateral lugs 3l will engage shoulders 6a in each of the notches 6 and will remain in engagement until the plates B assume a vertical position. 'Ihese plates, together with the follower plate, positively avoid sliding movement of the lower edges of the les along the bottom of the drawer. The lower edges of the files will thus remain under constant compression, and this is as it should be, as it is only the upper portions or edges of the files that require expansion when they are to be open for examination, etc.

In Fig. 2 the rear compression plate l0 is shown as hinged to the rear and bottom portion of the drawer. This is not absolutely essential, as the lower edge of the compression plate might be hook-shaped as shown in Fig. 6 to interlock with a similar shaped hook of the rear edge of the drawer.

While this and other features of the invention have been more or less specically described and illustrated, I wish it understood that various changes may be resorted to within the scope of the appended claims, and that the finish and materials may be such as the experience of the manufacturer may dictate and other conditions demand.
