To all whom, it may concern: v

Be it known that I, JOHN M. JENKINs, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Paper-Files, of which the following is a specification.

My invention relates to improvements in those receptacles for business documents and other papers in which two rectangular boards are connected at bottom and two sides by an accordion gusset, the space thus inclosed being separated into a number of compartments by means of partitions. In my improvement such gusset is composed of as many paper strips as there are compartments, and of which each strip is contcrminous with the bottcm and two sides of the respective compartment, and is so creased, cut, and overlapped and pasted at the cut parts as to possess an inwardly-extending crimp that serves to dis tend and permit expansion of the compartment and a pair of flies or wings, each of which and the corresponding wing of the adjacent crimp serve for attachment (by pasting) of the partition.

The formation of the respective parts of the gusset which are included between every two consecutive partitions of an entire strip of paper having wings by which it is pasted to the adjacent partitions,is thought to possessimportant advantages, both over those files whose gusset portion between each pair of such partitions consists of three strips, and over those whose entire gusset is composed of a single large sheet of crimped paper. Over those of the former class it presents the advantages of accuracy in form and dimensions over such loose and separable strips, of avoiding corner orifices where dust can enter and contents escape, and of its much greater strength and durability at its completely-closed corners on which the principal wear comes. It is also more quickly and therefore more cheaply constructed. Over those les whose gusset is composed. of a single sheet it possesses the advantage of attachment of each partition by pasting all around its margin to the crimp wings, thus holding all the vparts in their proper form and making impossible any bulging or demoralization of the crimps or displaeementof partitions consequent on the overcrowding of individual compartments. Hence the shape and efficiency of my ille are much longer preserved.

In the accompaiiying drawings, Figure l is a perspective View of a paper-file constructed on my plan. Fig. 2 is a dat View of one of the paper blanks out of which each crimp is formed. Fig. 3 represents a crimp formed out of such a blank by folding and pasting together the corners, accompanied by one of the partitions shown detached. Fig. 4 is a crosssection through three adjacent crimps and two attached partitions.

A A represent two similar cheeks or sides, preferably of card-board or pasteboard and of rectangular shape. An extension of one of these sides may form a flap, a..

B represents leaves or partitions of corresponding shape and dimensions to the sides, and of any suitable material, such as stout Manila paper.

C represents a blank of tough Manila paper 01' other suitable material, which, when partially severed, crimped, bent, lapped, and pasted so as to assume the form shown in Fig. 3, becomes one of the component members or gores of my gusset, there being one such member for each space or pocket formed by the neighboring partitions and by the end partitions and the neighboring cheeks. Each of such blanks, having been partially divided by transverse cuts c, corresponding to the locations of the file-corners, as shown in Fig. 2, is triply crimped, as shown at c' c c in Fig. 3, and its cut portions bent, lapped, and pasted, as shown at ci" c" of that ligure.

The portions of the strip C outside of the external crimps, c and c, form two iiies or wings, D D', to whose outer faces, d, and to corresponding faces of the neighboring and identically-similar gores the lower and end marginal portions of two consecutive partitions are pasted. The two end partitions are in like manner connected to the cheeks A A.

The gusset may at or near its free or exposed edges be strengthened by a re-enforce or binding, E, which, being pasted to said gusset and to the outside of the cheeks, prevents the separation of these parts by use.

Of a number of obvious advantages of this construction over that in which the gusset is IOO made to consist of a singlewsheet is the capacity of building rup a file ,o f any'k desired number of compartments, greater or less, to order, without change or waste of material.

5 The binding or re-enforce E, being continued around the outsideof the outer pieces- `or cheeks, becomes a binding to' th iaiiias well as to the gusset. I do not claim," broadly, the strengthening of gusset-margins by re-enio forces pasted thereto, such being old.

I claim as new and of my invention- 1. A paper-file consisting of the combination of cheeks A A, partitions B, and partially-v severed, crimped, bent, lapped, and pasted 15 gores o1' gussetsections formed fromblanksv 2. In a paper-le, the combination offthze y 25 cheeks A A', the pafiiiiiis B, iii@ eiimped I set my hand.

and foldedb gusset-sections C, each of which is yco n'temjinos with the 4.bottom and sides of the partitions B, each of said partitions being secured between the wings D D of two consecutive gusset-sections, and the re-enforoe E, 3o

pasted lvto the outerl side. of the upper margins of the gussets to prevent' their separation, substantially as' set forth.

3. In a paperle,vthe gusset composed of gores or sections formed from blanks C, Fig. 3 5 2, which, having been partially severed by cuts c that extend transversely from each edge inward at the places `for the file-corners, are interiori-y crimped, as Shown' ate c d, Fig.4
