the top and near the bottom, respectively, of the modified form of envelope insert shown in Fig. 7, and shows the tapered character of the side wall pleats.
Referring to Fig. 1, the numeral I represents generically an outer casing which may be made of metal, wood, cloth covered paper board, or other relatively stiff material, metal being pre ferred. The casing is composed of a front wall II, a rear wall I2, a fiat bottom wall I3 upon which file rests in the open and closed positions thereof, side walls I3a and a cover I4. The cover is pivoted to the rear wall I2 as shown at I5 and the upper portions of the front and side walls are bent back upon each other to form a reinforced structure as shown at I6 and are in- `wardly offset to accommodate the rim of the vlike attached to the insert which will now be described.
The rear flange I 'I extends downwardly for a certain distance, shown at I 8, for a purpose which Will be described below.
The front wall II is pivotally mounted, as shown at I9, upon the bottom wall I0, so that, upon lifting of the cover I4 it can be swung forwardly, almost to the horizontal position as illustrated in Fig. 2.
The casing I0 is provided with a lining or insert shown in the form of an expanding or accordion folder or envelope 20, provided with a series of pleats 2I which enable the envelope to expand and contract as the file is opened and closed. The envelope may be provided with partitions 22 which extend across the interior of the file and divide the latter into a number of compartments, the partitions being secured to the side pleats 2I and also to the bottom pleats 23, the envelope illustrated in Figs. 1 and 2 being one of conventional construction. The front double-ply wall 24, 24a of the insert is secured to the front wall II of the casing by means of a clamping plate 26 which has a lip portion 26a. for engaging over the front wall flange I6 and secures the insert wall against the front wall of the casing. The rear wall 25, 25a of the insert is secured to the rear wall of the casing by slipping it under the downwardly extending portion I8 of the rear wall flange I'l, the rear wall being preferably secured in position before the front wall. If desired, the clamping plate 26 may be permanently xed to the front wall II, similarly to the extension I 8, but particularly when the insert of the casing is to be frequently replaced upon becoming filled, it
will be found convenient to have the clamping plate 26 separate from the front wall as it then facilitates the insertion and attachment of the new insert.
The front wall I I is provided with side plates 28, which, together with the front wall, form a hopper which receives the forward portion of the opened envelope insert and protects the front and sides thereof against injury. The side plates 28 fit closely against the side walls I3a of the casing and are provided each with a circular slot 29 receiving a guide pin or stud 3D extending inwardly of the side walls I3a. The slots 29 serve to guide the movements of the front wall I I and also limit the downward movement thereof to avoid overstressing the paper insert.
As will readily be seen upon inspection of Fig. 2, the file in its open condition presents the expanding or accordion envelope in an expanded condition in which the contents thereof are conveniently arranged for inspection. Because it is pivoted at its lower end to the bottom wall, the front wall I I of the casing has an unusually large angle of opening, so that the insert is expanded to practically its full extent, the weight of the front wall acting to keep the envelope or insert open, while the cover I4, at least to some extent, balances the weight of the material to the left of the pivot I9. It will be noted that even in the fully opened condition of the le the pleats of the insert are for the greater part protected by the side walls I3a and the side plates 28 of the file. While the partitions 22 are not absolutely necessary, they are very desirable, because aside from the fact that they divide the interior of the file into convenient compartments, they keep the contents of the file from falling forwardly in a heap when the front wall II is lowered. These partitions, in contrast to the known loose index or separating cards employed with steel files having forwardly swinging front door portions, do not fall forward upon opening of the file, but, being held by the pleats, assume more or less uniformly spaced positions in which they afford ready access to the papers stored between adjacent partitions.
In the construction shown in Fig. 6, parts corresponding to the parts of the structure of Figs. 1 to 5 are identified by the same reference characters. In this modified construction, means are provided for causing positive opening of the file casing upon movement of the cover I4 to the open position. This automatic opening mechanism may take various forms and in the construction illustrated includes at each side of the casing, a link 3| pivoted at 32 to the cover I4 and connected at its opposite end to a bell-crank lever 34 which is pivoted upon a fixed fulcrum 35 secured to the side wall. The other arm of the bellcrank lever is pivotally attached to a link 36 which is pivoted at 31 to one arm of `a second bellcrank lever 38 which is pivotally mounted upon a pin or stud 39 fixed to the side wall. The other arm of the bell-crank lever 38 is attached at 4I to a link 39a which is pivotally connected with a pin or stud 4I secured to the adjacent side plate 28. The side plates 28 may be provided with cut-outs 42 to receive the pins or studs 39 as the front wall II is raised to closed position.
Comparing Figs. 6 and 7 it will be seen that upon opening of the cover I4 the link and lever mechanism 3|, 34, 36, 38 and 39a is operated to exert an outwardly directed force against the side plates 28 and compels the front wall to open as the cover I4 is drawn back.
rov
My improved le has further the advantage that it `is not necessary toy employ the expansible envelopes which are now in common use. In fact, a type of expanding envelope can be employed which is of simpler and cheaper construc- An envelope can tion than the known envelopes. thus 'be employed which is expansible only at the sides, the bottom thereof being of fixed dimensions. This will be clear from the fact thatwhen encased in a steel casing the paper envelope does not expand in a direction normal to the surface of the front wall of the envelope, but rather in fanwise fashion, the bottom ofthe envelope remaining of fixed width, corresponding to the width of the metallic (or cardboard) casing, while the upper portions of the file expand as the front wall of the casing is swung forwardly. 'Ilhe pleats along the sides of the envelope can thus be of tapered form, being narrowest at the bottom and widest at the top, corresponding to the degree of expansion to which it is subjected at various heights as the front wall casing is opened.
This simplified insert construction is shown in Figs. 7, 8 and 9. As illustrated 'in Figs. 8 and 9,
i which represent -sections through a pleated side of the insert taken at a higher and lower point, respectively, the sides of the pleat increase in width, and-hence the side wall as a whole increases in depth, toward the top of the insert, as
can be seen by comparing the 4pleat sides 44 and 43. By this construction, crowding at the bottom of the insert 'is avoided, and the absence of pleats in the bottom wall vof the insert increases the capacity of the file, as no space is occupied by upwardly extending pleats. In fact, the bottom wall of the insert may even beentirely dispensed with.
It will be seen from the above that I have provided a combined file construction wherein a lining or insert in the form of an expansible envelope is made very easily manipulatable by virtue of the fact that the rear wall is held to the rear wall of the relatively heavy outer casing, while the front wall of the insert or lining is held in its extended position by the weight of the front wall of the casing and also by the weight of part of the contents of the file. It will also be noted that whereas in the ordinary use of an expanding envelope the degree of expansion is substantially the same at both the top and bottom of the envelope, in my improved file construction the envelope is made to open in fanwise fashion which contributes greatly to the facility with which the contents of the le may be examined. On the l' other hand, a modification of the construction of the outer casing is made possible by the presence of the expansible insert,4 the insert making it possible to pivot the front wall at approximately its lower edge and thereby increasing the usefulness of the casing, for it then permits a wider angle of opening of the file.
Various modifications in the dimensions and arv rangements of parts may be resorted to within the scope of the appended claims without departin from the spirit of theinvention.
