F-ILE.

SPECIFICATION forming part of Letters Patent No. 673,387, dated May '7, 1901.

Application filed December 3, 1900. Serial No. 38,518. lNo model.)

To all whom t may concern:

Be it known that I, JAMES L. DEAN, a resident of Waterville, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Files; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved document or reference iile, the object of the invention being to providean improved device of this character which will greatly simplify the filing away of documents and references and which can be enlarged or diminished or rearranged at will.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my improvements. Fig. 2 is a view in section of the same. Fig. 3 is a View of one leaf removed, and Figs. 4L and 5 are views of details of construction.

1 represents a binding of any approved material, but preferably comprising st-i backs 2 and intermediate section 3, to which latter my improved binders t and 5 are secured, near the respective ends thereof. Thebinder 4 comprises aplate 6, secured to the portion 3 and provided at one end with aflap 7, projecting at right angles thereto, and having secured thereto a pin orpintle 8, disposed parallel withplate 6 and made with an annular groove or recess near its free end. To the other end of the plate 6 aflap 9 is hinged, as shown, and is made with ahole 10 to receive the pintle S and bent around said hole to form a spring-clamp to engage the pintle in the groove or recess therein to secure the pages in place. The other binder 5 comprises a plate 11, secured to intermediate portion 3 and provided at one end with ahinged flap 12, carrying apintle 13, which latter is made with an annular groove or recess 14 near its free end for a purpose which will now be explained. To the other end of plate 11v aiap 15 is hinged and comprises wparallel plates, between which aslide 16 is mounted. The inner plate of theflap 15 is made with a hole to receive thepintle 13, and the outer plate is made with a depression or recess to receive the end of the pintle after its passage throughslide 16, which latter is made with a 'slot 17 of greatest width at one end to permit the free passage therethrough of the pintle; but said slot gradually tapers to its other end, where it is of less diameter than the pintle, so that when the slide is moved to one extreme position the pintle canbe freely passed therethrough, but when moved to its other extreme position the slide will engage the recessed portion at the end of the pintle amd secure it against accident-al removal. 3L/The leaves of my improved file each com prise anenvelop 18 and acardboard stub 19, spaced therefrom and connected by afabric strip 20. In constructing the leaves the strip 2O is folded longitudinally and incloses and is glued to thestub 19, and the respective edges ofstrip 20 are glued to theenvelop 18, the intermediate portion thereof between the envelop and stub being provided, preferably, with lines of stitching, so as to hold the sides of the strip together, and thestubs 19 are punched to receive the pins orpintles 8 and 13 and secure the leaves in the binding.

By constructing the leaves as above described the intermediate flexible strip between the stubs and envelops will permit the envelops to lie fiat at any point the file may be opened and will compensate for the varying thicknesses of the envelops according to their contents, as some envelops may contain but little, while others may be almost full.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters IOO l. In a-documentiie,the combination with stiff coversnandaback connecting-.fsaidcow ers, of a series of stubs disposed between the covers, strips of flexible material secured to 'each stub and projecting therefrom forming a' pair of Iiaps, an envelopl glued between each pair of said flaps, binder-frames secured Within the back of the le and having two members disposed at right angles to eachiv other, a rigid pin projecting from one of said members and passing through the said stubs, and a flap hingedjao:each-.binder-frame to 4enf e gage the free end of said pinthereon. i

2. In a binder for a document-file, the combination of a plate having a flap at one end carrying a pin or pintle, and a flap hingedto theother end of, the plate andzhaving a hoie thereinito receive the free end o'rv thefpintle. Y 3. In a binder for a document-file, the combination of a plate having a iap at one end carrying a pin or pintle, a iap hinged to the other end of. saidplate and means thereon forlockingsaidiastLmen tioned flap and pintle together.

In testimony whereof I, have signed this specification in the presence of two subscrib ing witnesses.

JAMES L. DEAN;
