IMPROVEMENT INk ENVEL PES.

Specification forming part of i Letters Patent No. 192,522, dated June 26, 1877; application filed Mey es, 1877.

To all .whom it may concern.-

Beit known that I, CHARLES K. MARSHALL, of the city of Vicksburg, in the county of Warren and State of Mississippi, have invented a new and useful Improvement in Letter-Envelopes, which improvement is fully set forth in the following specication, reference being had to the accompanying drawings.

The object of my invention is the production of a letter-envelope adapted to perform the ordinary functions of two letter-envelopes, and this without reversing the original folding of an envelope, as has sometimes been done to accomplish such purpose. To this end I provide the face of a letter-envelope with two sets of superscription-lines and withtwo stamps, and its sealing-flaps with two mucilage-surfaces, so distinctly separated from each other that one may be utilized to seal vup the envelope on its first transmission through the mail, and the other on the return of the envelope through the mail.

The nature of my invention relates to an envelope which not only is capable of doing double service as such, but also furnishes a person to whom such envelope is addressed with the means of a reply without subject-ing such person either to the expense of postage or the expense of another envelope.

.Figure 1 is a plan view of an envelope constructed to carry out my invention, this View showing its superscription-face and the sealing-iiap extended out on the same plane. Fig. 3 is a plan view of the under side of the envelope shown in Fig. 1. Fig. 2 is a view of an envelope similar to view Fig. l, and Fig. 4 shows a plan view of the under side of the envelope shown in Fig. 2. Fig. 5 is a similar view of an envelope to that shown in Fig. l, and Fig. 6 is a view of the under side of the same.

In all of said figures, A indicates the body portion of the envelope, and A the sealingiiap, the said body and ap being made in the usual likeness ofthe ordinary envelope in common use, save in particulars, as hereinafter described. As shown in Figs. 1,2, and 5, b b b are lines' impressed upon the lefthand face of the envelope, as a guide for the superscrip tionaddress prior to its first mailing in a post-office, and b' b b are similar lines on its righthand face for a second superscription-address prior to a second mailing of the envelope in a post-office. Over these right and left hand lines b and b', at convenient points, postagestamps, as at c c', are placed, the left-hand stamp, c, being intended to prepay the postage on the first mailing of a letter within the envelope, and the righthand stamp, c', being intended to prepay the postage on a second mailing of the envelope and its contents. Of course, the lines b and stamp c can be utilized for the first mailing, and the lines b and stamp c for the second mailing, if need be, but for uniformity of address the face of the envelope may have directions printed upon it to write the rst address on the left,77 as signified in Figs. l and 2. The under side ofthe sealingflap Al in the several gures shows two sealin gsurfaces, or surfaces having mucilage thereon, to effect the usual sealing. of an envelopeto wit, an outer scaling-surface, as at d, and an inner sealing-surface, as at dl-so that when my improved envelope is irst mailed the letter contained therein can be sealed up within the envelope by utilizing in the usual manner the mucilage d for such purpose, after which, on a second mailing of the envelope, the muoilage, as at d1, can be in like manner used for a second sealing of the enveiope. In Figs. 3, 4, and 6 these separated sealing-surfaces d d1 of the flap A are indicated by section-lines, which runin reversed direction; and in Figs. l, 2, 3, and 4 the flap A' has a series of punctures, perforations, or slits, as at e, cut through the flap between the outer sealing-surface d v and the inner sealing-surface d1, as shown. These punctures or perforations may be in the shape of a round hole cut through the ap, as in Figs. 2 and 4;, or in the shape of a slit cut through the ap, as in Figs. l and 3, the same being made either in a right line across the flap or a regular curved line, in order to predetermine the line of fracture or separation of theouter sealing-surface d of the tlap from its connection with the inner sealing-surface d, when the envelope is first opened, after having once been sealed.

In Figs. 5 and 6 my envelope in shown without perforations between its sealing-surfaces d and d1, the intermediate space, as at d2, being imperforated and having no mucilage upon it.

In the case of the use of the envelope which has its flap perforated, as indicated iu Figs. 1, 2, 3, and 4, it cau be opened, after a firstsealing up, by running a pin or other suitable im-v plement along the line of the perforations, and thus readily disconnect the ap along said line. And in case the two sealing-surfaces d and d1 have no perforations between them, as indicated in Figs. 5 and 6, the severance of the flap along the line of the space d2 can readily be effected by a paper-cutter, scissors, or other proper instrument inserted between the flap aud the body of the envelope; and ou the outside of the Hap, over this space d2, directions for so opening may be printed.

I do not claim providing an envelope with two gummed surfaces on a single ap, for the purpose of permitting the postmaster to open and examine a letter and seal it again during its passage through the mail.

Iclaim- The new article of manufacture, consisting of a letter-envelope having two sets of superscription-lines, as at b and b', two postage' stamps for prepayment of postage, as at c and c', and two sealing-surfaces ou its sealing-Hap,

as at d and d1, substantially as and for the purposes described.

CHARLES K. MARSHALL.
