IMPROVEMENT IN BILL-FILES.

Specification forming part of Letters Patent No. 56,884, dated November 17,1874; application filed September 14, 1874.

To all whom it may concern Be it known that I, HORAGE'J. FROST, of Washington city, District of Columbia, have invented a new and Improved Bill-File; and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings forming a part of this specification.

Figure 1 represents a plan of the outside of the envelope as printed before being folded. Fig. 2 represents an inside view of same partially folded and in position to receive a letter or other document. Fig. 3 represents a see tional view, showing the letter or document secured in position. Fig. 4 gives sectional View of same, with duplicate flap. Fig. 5 represents the envelope folded. Fig. 6 shows opposite side or leaf of last fold. Figs. 7 and 8 show sectional views of same when folded, with contents.

This invention relates to the construction of a file-envelope, so as to secure the inclosures in place, and at the same time leaving them in position to be easily referred to without removing them from the envelope.

A, Figs. 1 and 5, shows body of envelope, with index and blank for name of correspondent, Ste. B represents flap, gummed so as to admit of being pressed down and secured, as in Fig. 2, the outer half of said flap being a multiplication of smaller flaps, made by notching or other means, and numbered, in dupli- These flaps are for the purpose of securing the contents of envelope in place, and at the same time giving ready access to any document inclosed Without removng the same from its position, and are numbered so as to fasten the letter at two points. Said flaps are turned back and pressed down upon the fold, as shown at point 0, Fig. 2, in position to receive the letter.

I have used in this case the odd numbers to designate letters received, and even numbers to designate replies, and find it a great eonvenience to secure copy-press copy in this manner forready reference.

0, Fig. 3, represents a letter secured in place. D, Fig. 4, represents simply a duplicate of flap B, (sectional view,) gumined on both surfaces, and inserted in the fold, and may be used when more flaps are required, or to secure more firmly larger documents by placing them between the flaps, thus securing them on upper and lower surface.

That part of envelope represented in space E is turned down, as shown in section, Fig. 8, to admit the folding of envelope when the file is full without injury to the body of same at the points of fold X.

Having described my invention, what I now claim as an article of manufacture is 1. The file-envelope herein described, con-
