FIIJNG ENvELoPE CarolineA. Spotts, Muncy,`Pa. v l Application october 17, 1940, serial no. 361,633 z claims. (ci. 12s-16.7)

This invention relates to a filing envelope of the type in which valuable documents and records are kept for future reference and it is one object of the invention to provide an envelope of such construction that it will be nre-proof as well as Water-proof. It will thus be seen that the contents of the envelope will not be damaged by re or by Water used to extinguish a fire, even if the envelopes are kept in wooden cabinets.

Another object of the invention is t o provide a filing envelope of such formation that sheets of Woven asbestos and oiled silk from which theenvelope is made will be securely held in cooperating relation to each other and the oiled silk held smoothly against the asbestos.

Another object of the invention is to provide a filing envelope which is soft and pliable and capable of being rolled or folded if necessary.

Another object of the invention is to so form the envelope that it is provided with a side extension for carrying an identifying tag.

The invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a view looking at the front of the improved ling envelope, with the lower portion thereof partially in section.

Fig. 2 is a View similar to Fig. 1, looking at the back of the envelope.

Fig. 3 is a view looking at the front of the envelope with the flap raised. Y

Fig. 4 is a sectional view on an enlarged scale, taken vertically through the envelope on the line 4-4 of Fig. 1.

Fig. 5 is a transverse sectional view on the line 5 5 of Fig. 1.

Fig. 6 is a sectional view through the ap on the line 6 6 of Fig. 3.

Fig. 7 is a fragmentary sectional view showing a portion of the envelope in detail.

This improved filing device consists of an envelope in which records and valuable papers and other documents are to be kept and preserved for future use or reference when necessary. It will be understood that the envelope may be of any dimensions found necessary to accommodate the 45v papers and other documents to be stored therein.

The contents of the envelope must be protected against damage by fire and water. Therefore, it is formed from a sheet I of asbestos or other suitable reproof material and a facing sheet 2 of waterproof material such as oiled silk. This is shown in detail in Fig. 7, and referring to this figure, it will be seen that the asbestos sheet I is formed of woven strands 3 and 4 of asbestos to provide a tough and pliable flreproof sheet which may be folded without cracking and will not deteriorate and crumble.

The facing sheet 2 of oiled silk is of greater dimensions than the sheet of Woven asbestos and has its marginal portions folded inwardly, as shown at 2a, and after such folding, the asbestos sheet and its facing sheet are folded as shown in Fig. 4, to form front and rear walls 5 and 6 of the envelope and the closure flap 1 which is folded downwardly against the upper portion of the front wall 5 in closing relation to the open upper end of the envelope when in closed position.

Lines of stitching 8 are then sewed through the folded sheets in spaced relation to opposite side edges of the front and rear walls and the closure flap, and another line of stitching 9 provided across the upper end of the front wall. Therefore, the inturned marginal portions of the facing sheet will be held folded and marginal edges of the asbestos sheet shielded against raveling as well as a neat appearance being imparted to the envelope.

The closure flap has its inner face covered with a facing sheet I0 of oiled silk which is secured along its inturned margins by sitiching I I.

At one side of the envelope, the closure flap is extended to form an extension la constituting a carrier for a tag I2 which may be secured to the extension in any desired manner such as .by securing it between the inturned marginal portions of the facing sheet I0 by the stitches II or being pinned to the fiap by the user. The tag is so located that it projects upwardly when the fiap 'I is closed and identifying markings on the tag may be readily seen. The inner or rear face of the extension is faced b'y an end portion of the facing sheet I0 and its outer or front face has been shown covered by a facing sheet I3 secured by stitching I4, but it is to be understood that this facing I3 may be formed by an extension of the upper portion of the facing sheet 2 or the facing sheet IIJ may be of increased length and have an end portion folded about the outer side edge of the extension 1a and secured by stitching in position to cover its outer face. A button I5 is secured against the outer face of the front Wall 5 and the closure ap is formed with a buttonhole I6 to receive the button and releasably hold the closure flap in closed position. Snap fasteners or other suitable fastening means may be provided to hold the flap closed instead of the button and buttonhole, if desired.

Having thus described the invention, what is claimed is:

1. A filing device comprising a sheet of Woven asbestos strands', a facing sheet for the asbestos sheet formed of oiled silk, the said sheets being folded to form front and rear walls of an envelope and a closure ap for the envelope, the facing sheet being of greater dimensions than the asbestos sheet and having marginal portions folded inwardly against inner faces of the asbestos front and rear walls and closure flap and constituting shields for edges thereof, lines of stitching passing through ,the asbestos sheet and the facing sheet to hold the facing sheet smoothly against the asbestos sheet and secure the side edge portions of the front and rear walls together, and a fastener for releasably holding the flap closed.

2. A filing device comprising a sheet of Woven asbestos strands, a facing sheet for the asbestos sheet formed of oiled silk, said sheets being folded to form front and rear walls of an envelope and a closure nap for the envelope, the facing sheet being of greater dimensions than the asbestos of the extension, a facing sheet of oiled silk for the outer face of the extension, and stitching sheet and having marginal portions folded inwardly against inner faces of the asbestos front and rear walls and closure flap and serving as a shield and reinforcement for edges thereof, lines of stitching passing through the asbestos sheet and the facing sheet to hold the facing sheet smoothly against the asbestos sheet and secure the side edge portions of the front and rear walls together, the flap-forming portion of the asbestos sheet having an extensionV at one side extending its full depth and projecting laterally from a side of the envelope when ythe ap is closed and constituting a carrier for an identifying member, a portion of the facing sheet being extended at one side and covering the inner face securing the facings for the extension to the same.
