8 Claims. (Cl. 129-26) This invention relates to drawers for filing cabinets and more particularly to a novel construction having special utility in drawers of the type having a tilting front or drawer head.

One of the objects of the invention is to provide a spring tensioned front plate or presser leaf mounted within the drawer adjacentthe drawer head to prevent the drawer contents fall ing forward when the drawer head is tilted outwardly as the drawer is pulled open, but which may be readily moved or swung outwardly by manual finger pressure to release the drawer contents and permit ready removal thereof.

Another object is to provide safety means 00- operating with the pressure plate for preventing the drawer head from being'forced open when the filing space is full or crowded and the drawer is closed. That is to say, while the front plate or presser leaf is capable of movement independently of the drawer head when the latter is tilted forward, nevertheless, when the filing compartment becomes crowded the presser leaf cooperates with the drawer head holding means to prevent accidental opening of. the closed drawer head due to the expansive forceof the filed material.

In that connection, the safetymeans also has a-icompressive eifect'on the plate-to cause the sameto act as a compressor under these conditions.

{ i With the above and other objects in view which will more readilyappear asthe nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts hereinafter'more fully described, illustrated and claimed.

"A preferred and practical embodiment of the inventionis shown in the accompanyingdrawings, in which: p 7 l Figure 1 is a vertical sectional view of a drawer 54b embodying the present invention, a portion of. the drawer head-being shown in side elevation, and in closed position. Figure '2 is a view similar to Figure 1 showing the drawer head tilted to open position.

'45 Figure 3 is a view similar to Figure 1 wherein the drawer head is closed but the compartment between the presser leaf and the space regulator is overcrowded with filing material.

Figure 4 is a top plan view of the construction '56 shown-in Figure 2. 1

Figure 5 is a vertical sectional view taken on the line 5- -5 of Figure 1.

:Figure 6 is a perspective view of the drawer head holding mechanism which constitutes ,a part 55 of the safety means.

Similar reference characters designate corresponding partsthroughout the several figures of the drawings.

According to the embodiment of the invention shown in the drawings, the same includes in its 5 organization, a drawer designated generally as A and which includes the usual bottom and side walls and a back wall (not shown) and having at the front thereof a pivoted drawer head B adapted to tilt outwardlyfrom a vertical position on 10 a pivot B. Within the drawer A is provided a suitable space regulator or follower C intended to regulate the length of the filing compartment and which cooperates with a novel presser leaf D to maintain the filing material in neat and ori5 derly condition.

The presser leaf or front plate D is located between the drawer head B and the space regulator or follower C and preferably consists of a body of sheet material substantially coextensive with the width of the drawer. The lower end of the presser leaf or front plate D is mounted on a pivot I carried in suitable brackets 2 mounted at the front end of the drawer bottom adjacent the pivot B for the tilting front or drawer head. As will be apparent from Figures 4 and 5, the plate D is preferably forced in one direction by a series of coil springs 3. That is tosay, the plate is tensioned to move toward the space regulator C and for'the purpose of maintaining the same at an 3 inclination substantially corresponding to that of the space regulator, the upper corners of the plate are provided with the laterally offset ears or lugs 4 (Fig. 4) intended to rest on the upper edges of the side walls of the drawer. The lugs 3 or ears 4 may be provided with suitable cushioning means 5 of felt or rubber to deaden the sound of the plate engaging with the drawer when it is released to permit the springs 3 to exert their force. The presser leaf or front plate D is in 40 tended normally to occupy the position shown in Figure 1 when the compartment formed'between the plate and the space regulator contains only the proper amount of filing material. On the other hand, if the filing compartment is crowded with filing material as indicated by the dotted lines in Figure 3, the plate D may assume a more nearly upright position. When the plate is in the position shown in Figure 1, and the drawer head 3 is closed, that is, in its vertical position, the presser leaf functions merely to serve as a front abutment for keeping the filing material in position. Also, when the drawer is opened by being pulled out of the cabinet and the tilting front ,7 is moved forward on its pivot B, as shown in Figure 2,the plate D will still assume the position shown in full lines in Figure 2 to prevent the filing material from falling forward against the inside face'of the tilting front or drawer head. 5 However, when it is desired to remove papers filed behind the plate D, it is only necessary to subject the upper edge of the plate D to finger pressure as shown in Figure 2 and pull the same in the direction'of. the dotted arrow to open up the space between the plate and'the regulator C. Therefore, it will be apparent that the front plate or presser leaf D, under normal conditions, oper l ates independently of the tilting front ordrawer head B to maintain the filing material in proper regulator C, the presser plate performs the important function of preventingthe expansive force of the overcrowded filing material ircrn forcing the tilting front or drawer head open, as will presently appear more in detail.

4 Referringto the tilti n front or drawerhead B, it may be observed that" the same is provided with the. side Wings 6 which are tensioned by the siirm'gst in the manner set forth in Patent No. r 1,326,503, issuedsepte mber 12, 1933. The wings 'lr areiprovided with 'abutments l for engaging aist abutment 8 onthe drawer to limit the outmoveinent of the drawer head on its pivot 13"." As will also be observed from Figures 1 and 2 'th einsidejface of the side wall of the drawer is provided with arigid holding stud 9 adapted to cooperate with a holding arm lfl pivoted as at I I tothe inside face of the wing 6. At one end the arm ill is 'formed with a head !2 provided with a nose [3 and a shoulder Hi while the opposite end is provided with a laterally offset portion 15 adaptedito'oper'ate in 'a slot It in the wing. The said laterally offjset "portion is is provided with th I l and it which extend to opposite sides thereof; Normally, the spring finger l'i' engages. the inside face of the drawer head while other ldfis intended to be engaged by f d d'fi it '8?

However, in the'event that the filing" material is crowded into the space ahead 'of the to turn the safety arm 10 in the same direction so that whether the tilting front is open or closed, the arm I0 will always be maintained in position either to engage the stud 9 or directly in engagement with it as the case may be, while at the same time when the drawer is crowded with filing material, the portion ifi will engage the spring finger i8 and cause the parts 9 and I lto engage with more force than provided by that of the finger I? alone. A

It will, of course, be understood that the arms It may be duplicated at opposite sides of the drawer as shown in Figure 5, or, in other words, each wing 6 of the drawer may be provided with holding means for assisting in maintaining the drawer head in its closed position.

'In use, the plate D serves to always keep the filing material in orderly fashion and also cooperates with the spring finger l8 of the safety arm or latch id to maintain the drawer head closed under abnormal conditions. a
