l'lO WHOM IT MAY CONCERN:

Be it known that I, SIGMUND ULLMAN, of the city, county, and State ot New York, have invented a new and improved Envelope; 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 beinghad to the accompanying drawings, forming a part of this specification.

This invention relates to a new and improved mode of cutting envelopes, whereby the same, when folded and fastened or sealed, will` not admit of letters or documents being abstracted without defacing or tearing the envelopes. v

The invention further relates to a new and improved application of an eyelet-seal or fastening to the euvel ope, whereby the former are permanently attached to the latter, so that they may be sold with them, and purchasers or users enabled to seal the envelopes with the greatest facility. i i I Hitherto, envelopes which have been sealed with eyelets have been sold separately from the latter, and th purchasers or users were required to purchase two different articles, envelopes and eyelets, which causes considerable diH-lculty and embarrassment, and therefore they have not come intogeneral use.

In the accompanying sheet of drawingsiFigure l represents a view of an envelope in an open or unfolded state, and cut according to myinveutiou.

Figure 2, an enlarged view of the samein a folded state.

Figure 3, a transverse'section of iig. 2, taken in the line z x, fig. 2.

Figure 4, a view of a portion of the same, in which the seal-eyelet is fitted.

Figure 5, a section of g. 4, taken in the line y y.

Similar letters of reference indicate corresponding parts.

The main portion or body of the envelope is of rectangular form, or has parallel edges, a a, and ends, b li, and is folded three times, as indicated by the figures 1, 2, 3, in fig. 1.

The portion of the envelope included between the folds 2 and 3 has small iiaps, c c', at its ends, and these iaps comprise the only variation the envelope has from a rectangular form. The position of the folds, when the envelope is closed up, is vshown clearly in iig. 3, the letter or document being shown in red.

`When the fiaps c 4c are turned over, and one eyelet, d, passed through them, every part formed by therthree folds, l, 2, and 3, will have the eyelets passing through them, as indicated by the holes ff in iig. 1.

In putting up the envelopes for sale, the eyelet of the Hap c is riveted, and said flap gummed down. The other a p, e', is left open, and 'its eyelet, d, secured in it, by gumming a strip of paper or other suitable material, e, over said eyelet, at the'outer side of the flap, and over the inner side also, if desired,=('see more particularly iig. 5.) By this means the eyelet is secured to envelope, and is put up and sold with them, eyelet-holes,'

f', being made through the end of the envelope, to receive the eyelet,so that all the purchaser or user is required to do, in order to seal the envelope, is to moisten the inner side of flap c,-turn itover, and pass the eyelet through the holesf, press the ilap against the body of the envelope, so that it will be gummed thereto, and then rivet the eyelet, which may be done by means of a small punch or other suitable device.

The object in gumming the iiaps c e/ is simply to prevent envelopes catching into cach other in their transit through the mail. The-gumming adds nothing to security; the eyelets are sufficient for that purpose.

The object in folding theenvelope thrce times in the' lines 1, 2, 3, is to produce an increased number of folds for the eyelet to pass through, as each additional foldv increases the diiiieulty of opening the envelope without detection.

Having described my invention,.l claim as new, and desire to secure hy Letters Patent- Securing the eyelet cZ in the open iap e of the end, hy gumming a strip of paper over said eyelet, at the outer side of the flap, as herein shown and described.

SIGMUND ULLMAN.
