' FILING DRAWER OR THE LIKE Filed June 19, 1955 ATTORN EY Patented Dec. 6, 1938 UNITED STATES PATENT OFFICE FILING DRAWER. OR THE LIKE Walter F. Regenhardt, Cleveland, Ohio Application June 19,

'1 Claims.

The present invention relates to filing drawers or the like and more particularly to filing drawers employing a follower file-back. One of the objects of the present invention is to provide for the quick release of the follower filing-back so that it can he slid horizontally within the drawer and to insure a binding relation between the back and the drawer wall accomplished by the manipulation of the file-back itself.

Another object of the invention is to provide a plurality of abutments on the drawer to be engaged by members on the file-back to limit the movement of these members and thereby limiting the rearward movement of the file-back and which members are released from their binding relation with the abutments by merely pulling forwardly on the upper part of the file-back.

A further object of the present invention is to pivotally attach a plurality of camming members on the file-back which members are adapted to cam themselves into binding relation with abutments in the file drawer when force is exerted rearwardly at the upper part of the file-back and which are arranged to release this binding relation by merely pulling forwardly on the upper part of the file-back.

Further objections and advantages will be' apparent from the following disclosure, reference being had to the accompanying drawing wherein a preferred form of embodiment of the present invention is clearly shown:

In the drawing:

Fig. 1 is a longitudinal sectional view taken on line of Fig. 3 and also shows part of one of the guides broken away.

Fig. 2 is a fragmentary view similar to Fig. 1 but showing the follower file-back in a different position; and V Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Referring to the drawing, and for the purpose of illustrating the application of the present invention'in connection with a filing drawer for file cabinets, there is shown a drawer 28. The opposite sides 2| and 22 and the bottom 23 of the drawer are preferably formed of sheet metal. A front 25 is suitably attached to the sides and bottom walls and is provided with a pull 26. From the point 21 and rearwardly thereof the upper edges of the sides 2| and 22 are bent inwardly to form abutments 28' and then downwardly as at 29 to provide open bottom horizontal extending guides at the upper ends of the side walls.

1935, Serial No. 27,283

The follower file-back 3| is also preferably formed of sheet metal and the lower part 32 is bent back on itself 'to form the slot 33 and is attached at 34 to the main body of the back 3| by spot welding or by rivets 36. For the purpose of providing a facile manner of releasably holding the follower file-back in position, I provide members on the file-back which are arranged to impinge with the abutments 28 and the bottom wall 23 of the drawer 28. The bottom wall functions as an abutment for the members. These members include a U-shaped camming member 31 having legs 38 and 39 and a connecting yoke 40. The yoke 40 is arranged to slide on the bottom 23 of drawer 20 and the legs 38 and 39 slide along the side walls 2| and 22 of the drawer 20. The entire upper edges of legs 38 and 39 are inclined rearwardly to form camming surfaces 42. The file-back 3| is carried between the legs 38 and 39 and is pivotally connected to these legs by a roller 43 and a pin or shaft 44. The shaft 44 extends through the roller 43 and the opposite ends thereof are journaled in the legs 38 and 39. The roller 43 is disposed within the slot 33. Camming members 46 and 41 are arranged along the inner opposite sides 2| and 22 of the drawer 20 and extend into the guides formed by the downwardly extending portions 29 of the sides 2| and 22. The lower edges of the cam members 48 and 41 are inclined to form camming surfaces 48 which correspond in an angular inclination with the camming surfaces 42 of the U-shaped camming members 31. A roller 50 is disposed in the upper part of slot 33 and receives a pin 5| which in turn has its opposite ends journaled to the cam members 46 and 41.

Fig. 1 of the drawing shows the follower fileback in its file holding position. When the upper part of the file-back 3| is moved forwardly, as shown in Fig. 2, the camming members 46 and 41 will be moved forwardly because of the interconnection of said file-back and members 46 and 41 through the roller 56 and pin 5|. The camming members 46 and 41 will then slide downwardly on the camming surfaces 42 to release the binding relation between the camming members 46, 41, yoke member 4|] and the abutments 28 and 23; it being understood that bottom wall 23 of the drawer 28 forms an abutment for the camming member 31. When this binding relationship is released, the file-back 3| and the camming members 31, 46 and 41 can be slid horizontally on the bottom wall 23. When it is desired to fasten the file-back in position, it is necessary only to rotate the upper part of the file-back in a rearwardly direction. This will cause the camming surfaces 48 to slide upwardly on camming surfaces 42 whereby the camming members 46 and." will engage the top abutments 28 and then by exerting a little more force in the same direction, the camming member 31 will be impinged tightly against the bottom wall 23 of the drawer.

If no front is provided, the file-back 3| and camming members 31, 46 and 41 can be inserted from the front as an assembly, or, this assembly can be inserted from the rear. However in the present embodiment wherein a front is provided for the cover and the rear is folded in as at 53, the assembly is inserted into the drawer from the top, and to accomplish this, the guides 29- stop at 21 so that the assembly can be inserted forward of this point.

From the foregoing, it will be seen that it is necessary only to rotate the file-back itself in a forward direction in order to release the same for sliding movement in the drawer and in order to hold the file-back in a desired position, it is necessary to rotate the file-back itself in a rearwardly direction.
