TO ALL WHO IT MAY CONCERN:

Beit known that I, JOHN W. WrLCoX, ot' the city, county, and State of New York, have invented a new and useful Improvement in Envelopes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure I is a plan view of the paper as cut and creased for folding and forming my improved box-envelope.

Figure 2 is a top View of the envelope when nished.

Figure 3 is a longitudinal section of my improved box-envelope taken in the line x :r,'ig, 2

Figure 4 is a transverse section ot' the same taken in the line y n fig. 2.

Similar letters of reference indicate like parts.

This invention relates te an improved mode of forming box or document-envelopes, and consistsin so cutting the paper or other material of which they are made as to involve the least possible waste, and in creasing and folding the ends of the envelopes together in such manner that they are fortied and sti'ened by a double thickness of the material throughout and a treble thickness at the corners, whereby the box-envelope is formed wholly of'one sheet, and is very materially improved in construction, and made stronger than by any known method of arrangement.

For cutting theform or pattern of the envelope :md creasing it for folding, as represented in tig. 1, I employ the usual tools and processes of the trade, and out the paper or other material in the geometrical propertions required to make the ordinary rectangular envelope for containing documents, commonly called boxenvelopes, which are in the form of a parallelopiped.

In g. l, A is the back of the envelope, B the top, and C the Hap. The dotted lines a a in the drawing indicate the creases in which the folds of the envelopes are made'to give it the proper form for construction and use. On the ends of the envelope creases are made at proper distance from the outer edges and parallel to them, and inline with the cut at the ends of the flap C. These creases extend across the pat-tern ofthe envelope, to make aps for turning up and forming the ends o' the box-envelope, b b being the flaps thus provided on the back A, and c e the. flaps on the top Between the aps b b and e c', at each'end ot' the envelope, are small flaps ortongues 0l d, and on `the opposite ends of the aps 6 b are similar small flaps or tongues e e, which ilaps are all made by cutting away narrow strips of the material, or" by'division cuts running from the edge ot' the pattern to the creases for folding. ,y

When the pattern has been cut and creased in this manner, the box-envelope is formed by'folding the top B over the back A in the usua'l way, and in such manner that the end aps 6 and c c shall lie against and in each other at their respective ends, and be pasted or gummed together, as shown by iig. 3. By this arrangement of the parts, the ends of the box-envelope are made of double thickness of the material throughout, to give strength precisely whereit is most needed, and furnish substantial transverse supports for the envelope. The small flaps or tongues e e and d d are also folded in and pasted down upon the ends, either between the deps b b and c c or on the inside, as desired, and as shown in iig. 4. This arrangement of the small flaps, so far as they extend, makes a treble thickness of the ends, and, being in the corners .of the envelope, aii'ords great additional strength at vpeints which require fcrtifying. A further improvement in the construction oi' envelopes is doubling and pasting two angular flaps ff within the top B, which are formed by making ono division cut running a short distance from the edge, and creasing from its terminus to the edge atl any desired angle, as shown by fig. 1. These ilaps add strength to the middle of the envelope, where the ends of documents are introduced and the tie ofthe flap binds, which is a point of importance and value. The flap C is turned over, and secured in the ordinary way when used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Constructing a box or document-envelope, with double ends throughout and treble ends in part, by folding and uniting flaps 4cut out of one sheet of paper or other material, substantially as herein described.

The above specification of my invention signed by me this 5th day of October, 1866.
