Sept. 28, 1943. M. WINOKAR MULTIPLE FIL'ING POCKET Filed Sept. 1. 1942 Jaws?? Mazda MW I W Patented Sept. 28, 1943 MULTIPLE FILING POCKET Maurice Winokar, Chelsea, Mass, assignor to Federal File Envelope Co.,.Inc., Boston, Mass., a corporation of Massachusetts Application September 1, 1942, Serial No. 456,858

2 Claims.

This invention relates to a multiple filing pocket characterized by novel features which are particularly useful and valuable for certain kinds of filing.

It is an object of the invention to provide a filing pocket especially adapted for filing sets ofv papers or documents in which a few papers should be segregated from the main collection.

It is a further object of the invention to provide an improved multiple filing pocket which is compact in form and economical in structure.

In accordance with the invention, a filing pocket is made with a front wall and rear wall connected by-a bellows element which extends along the bottom edges and part way up the side edges, each of the walls being double so as to form a pair of open-top envelopes'which can be used as auxiliary pockets for filing related papers.

For a more complete understanding of the invention, reference may be had to the following description of an embodiment thereof and to the drawing, of which- H Figure 1 is a perspective view of a filing pocket embodying the invention; 7

Figure 2 is a section on the line 2-2 of Figure 1; and I Figure 3 is a section on the line 3-3 of Figure 1.

The filing pocket illustrated in the drawing is made preferably of suitable materials to stand in the strip before the cementing is done, in which case the tube is formed initially in its flattened shape.

considerable handling and to wear well. As

shown, the pocket comprises a front member ill, a rear member I2 and a bellows element l4 connecting the members In and I2 and extending along the bottom edges thereof and at least part way up the sides thereof. Each of the members ill and I2 is in itself a pocket or envelopev open.

at the top to receive papers and to hold them separate from the more commodious pocket formed by the bellows element [4 between the front and rear members.

The front member Ill may conveniently be formed by taking a strip of heavy'sized paper, such as tag stock or the like, having a length a little more than twice that of the finished filing bers of papers or documents. Hence, the filingpocket and a width equal to the height of the The bellows element M may be made of a strip of sheet material in the customary corrugated form with longitudinally-extending angular ridges and grooves. Any suitable material having the proper degree of flexibility maybe employed. For example, a strip of textile material suitably stiffened with sizing, a layer of paoenor otherwise, is frequently employed for thispurpose. The width of such strip is selected in accordance with the desired capacityof the filing pocket of which it is to bea part. The number and height or depth of the ridges and valleys may be varied as desired. In the example'illustrated in the drawing, three valleys are shown having a depth of half' an inch or so. 1

In assembling the filing pocket, the'flattened tubes are cemented to the bellows element M in such a manner that the bottoms of the fiatpocket, a layer of reinforcing sheet material 24,'

such as cardboard, cloth or the like, is cemented against the outer face of each flattened tube It. As a result of such assembling, the longitudinal margins of the bellows element are thus ce-.

mented between marginal portions of the fiattened tubes and their corresponding reinforcing layers.

This results in a filing pocket having a capacious cental pocket adapted to receive a cornparatively large number of papers, the front and rear walls of the pocket being normally flat but being capable of receiving relatively smaller numpocket is not only relatively compact in structure but is adapted to receive and'to keep separate three sets of documents which may be related to common subject matter.

I claim:

I 1. A multiple filing pocket comprising a front member, arear member, and'a corrugated bellows element connecting said members and extending along the bottom edges and a portion of each of the sideedges thereof, each said member comprising a flattened tube of stiff sheet material open at the top and bottom, the bottom] of each said member being disposedin the outer most corrugations of said bellows element.

The longitudinal margins of 2. A multiple filing pocket comprising a front ing layer of sheet material cemented to the outer member, a rear member, and a corrugated belface of the flattened tube, the longitudinal marlows element connecting said members and exgins of each of said bellows element being cetending along the bottom edges and a portion of mented between marginal portions of one of said each of the side edges thereof, each said member 5 flattened tubes and its reinforcing layer. comprising a flattened tube of stiff sheet material open at the top and bottom and a reinforc v MAURICE WTINQKAR.
