- Specification of Letters Patent.

Patented Ang. 1i, 190s.-

` j Application led March 27, 1907. Serial No. 364,8-25.

America, and resident of La Grange, Cook county, Illinois, have invented'a certain new and-useful Im rovenient in Reversible En? velops, of whic 1 the following is a specification.

"fas

. velop sealed forthefirst time.

My .invention contemplates an improved reversible envelop--that is to say, an envelop which can be torn open and turned Wronv side out, and then reversed for a secon transmission through'the mails.

i My improved envclo i, as herein disclosed,-

s two end fla s 'whic are guinmed on the `\\i1inei' sui'facest ereof, and u per and lower flaps which are gummed a ong the inner' edges thereof. Said up er and lower flaps are-` also scored along tieir edges, so4 that these flaps can be torn off with clean edges. After this, the'end flaps can be reversed, and the top and bottom flaps may then. be reversed and sealed by moisteniiig the mucilage on the surfaces of the end flaps. Irr this way the envelop is readily reversible and can be used a. second time for transmitting a letter through themail. i

In the acconipanyino drawings'Figure 1 shows the inner side of the blank from which my envelop is made. .Fim 2 shows the en- Fig. 3 shows the top and bottom flaps of the envelop torn off or disconnected, leaving narrow portions iidherinv to the outer suifaces of the envelop. Fig. 4 shows vthe enti-re envelop reversed or turned wrong. side out, the bottom flap secured in place and the upper flap ready to be turned domi and secured in place by moistening the inueilage on the outer surfaces of the two end flaps. A

As thus illustrated, my improved envelop blank has a middle or body portion A provided with end iaps a and'upper and lower or top and bottom flapsfl' and at. The end flaps are gummed at 1 2, and 3 4, on the inner surfaces thereof, as shown more clearly in Fig. l. The flaps a, a- -are scored at 5-6-7 and 8, near the outer edges thereof, and are guiiimed on their inner surfaces. It

will be seen that the inueilage for the said upper'and lower flaps is applied between the score lines and the outer e( 'ges of said flaps. It will be readily understood that by score lines I mean the rines of perforations vfhereby the marginal portions oi the said flaps can be leither surface thereof, comprising to UNITED srnins PATENT OFFICE; V

outer surfaces of the envelop as's'hown i'n Fig. 3. The first time the envelollis u'sed the end flaps a are turned in, and t bottoni flaps are folded over and secured in place, as shown in'Fig. 2. The receiver .of the envelop can then tear the top and bottom flaps along thescore lines, as shown in Fig.- 3,. leaving narrow strips adherin to the outer surfaces of the envelop. licse narrow csf strips can then be broken to erinit the end jf flaps a to be reversed or fo ded back and' brought intothe positions shown iri Fig. 4,

bringing the gummed portions 1-2 and 3--4 into position toreceive 4the marginal portions of the said top and bottom flaps, as shown more clearly 'in Fig. 4. When this is done the narrow adhering ortions of the fla s will be concealed within t ie envelop, and t e lat teris now ready for use a second time. I n

this'way the envelop is readily rcversible'land.

need not be thrown uway'lwhen it is received for the first time. The return card of ,the first. user can be rinted on the outside of the blank and the at dress of the first user can be printed on the inside thereof, if such is del' sired. The envelop shown is left blank, sof.

that the address andreturn'cardcan written thereon. In the manufacture of the blank, the same need not be turned over, as the gumming is all on the 'same side thereof, and only one guinniing operation is necessary for cacht lank. What I claim as my invention is:"-

1. A reversib' be folded and 0umnied together to expose bottoin fia-ps having detachable ad erin portions, adapting said flaps for reveisal, an end aps which always go inside of the top and bottom fla s. i

2. A reversib e envelop blank having end flaps guinmed on the inner surfaces thereof, top and bottom flaps guinined on the iin'er surfaces thereof, said top'and bottom aps beingscored parallel with and near their outer edges to provide each flap with a detachable adhesive ortion, the um or adhesive material on tiie end flaps )eing adapted to receive the top and bottom flaps after the lat-ter are reduced by tearing them along their scei'c. lines.

- 3. A rcve'rjsible envelop blank having end 'ifoo ie envelop blank adapted to and surfaces thereof, apluialityofrsaid flaps be- 10 either direction', the upper and lower a s having detachable adhesive ends 'to ma e the envelop reversible. 5.

tachsble end portions X and Y which go in- 20 side when the envelop is reversed, said topf and bottom flaps beinff guninied between the said score lines and their outer edges, substantislly as s'et forth.

6.- The improved reversible envelop, p'ro- -25 4vided with end flaps pummed on the inside to receive the to `and bottom flaps when the envelop is used t e second time, said top and bottom flaps having deteohablelapping end.
