Patented Apr. 14, 1931 HOWARD E. HARSON, OF CHICAGO, ILLINOIS COMBINATION ENVELOPE AND LETTER SHEET Application. filed June 14, 1928. Serial No. 285,338.
The present invention relates to a combination envelope and letter sheet, and aims to provide a novel and improved article of this character whereby the possibility of placing Q1 letters in wrong envelopes when mailing a number of letters is avoided, and the letter may be readily detached from the envelope for the purpose of separately filing said letter.
Another object of the invention is the provision of a combination envelope and letter sheet constructed of a single piece of paper which will permit the printing of the return address of the senderon the envelope and the letterhead of the sender on the letter sheet in a single operation of a printing press.
A further object of the invention is to provide a combination envelope and letter sheet which may be sealed for first class mail, 29 and which may also be used as third class mail where it is necessary to leave the envelope unsealed in a condition for postal inspection.
A still further object of the invention is the provision of a combination envelope and letter sheet in which the letter sheet is an extension of one side wall of the envelope, while a closure flap is at the upper edge of the other side wall with gussets between the ends of the side walls connecting the same together, the ends of the material forming said "ussets extending over the outer side of the side wall carrying the letter sheet for forming flaps under which the closure flap maybe arranged when mail is sent third class.
It is also an object of the invention to provide an article of the above indicated character, which is simple and substantial in construction, which can be manufactured economically, and which will be thoroughly efficient and practical in use.
With the foregoing and other objects in view, which will be apparent the descrip tion proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing 50 from the spirit of the invention.
The invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a perspective view of my im proved combination envelope and letter sheet showing the envelope open with the letter sheet arranged eXteriorly thereof,
Figure 2 is a perspective view of the envelope arranged in the same position with the letter sheet folded and arranged within the envelope,
Figure 3 is a vertical cross section through the envelope and letter sheet, said envelope being in open position with the letter sheet folded and arranged therein,
Figure 4 is a plan view illustrating the manner in which the envelope and letter sheet are cut from a single piece of paper, and showing the same arranged prior to the folding thereof,
Figure 5 is a plan view illustrating the manner in which the envelope and letter sheet are arranged when printing a return address on the envelope and a letterhead on the letter sheet.
Figure 6 is a rear view of the envelope illustrating the position of the flap when used in connection with first class mail, and
Figure 7 is a similar view illustrating the position of the closure flap when the article is used in connection with third class mail.
In carrying out my invention the combined envelope and letter sheet is n ade from a blank of the configuration shown in Fig. at of the drawings adapted to be folded upon itself as indicated by the dotted lines, saii blank comprising a rectangular shaped portion 10 forming the front of the envelope and defined by the dotted lines, the back 11 of approximately the same size and shape as the front, and a letter sheet let extended from the outer end of the back but not as wide so that it may be folded into the envelope, with the portion of the blank forming the front and back extended at each side, as at 20, and
said extensions cut away from the back to provide the rear flaps 18 18 and gussets or end closures 18a 1864, the latter being integral with the front portion and each foldable between the front and back on the dotted lines 21. In addition to the rear flaps 18 18 the blank is shaped to provide a main flap 12 extended from the outer end of the front portion 10 of the envelope, said main flap having a gummed edge 13 and likewise the rear flaps are provided with gummed edges 23 and 9A- for connecting them together at the back of the envelope and to the back portion 11 when it is desired to completely seal the envelope, it being noted that for convenience in severing the letter sheet the blank is providedwith slits 15 leaving the narrow connections 16 at the jnncture of said letter sheet with the back portion, and as a guide in folding the letter shoot it is provided at its opposite edges with short lines or marks 17.
in making up the envelope from the blank hereinbefore described the main flap 12 is first folded down temporarily on the front portion 10, the side extensions 2t) are then folded inwardly over said flap on the dotted lines 19 and then outwardly the dotted line 21 of the gusset, after which the back portion 11 with the letter sheet if extending therefrom is folded to overlie the folded gussets and main flap so that the flaps 18 may be folded towards each other and the overlapping inner ends pasted together to complete the envelope in the form shown in Fig. 5 in which condition it is furnished to the trade; that is to say the face of the envelope and one side of the letter sheet form the front of the device on which the sencers card 25 and letterhead 26 are printed respectively and on which may be typed both the address on the envelope and letter on the sheet without removing the combined envelope and letter sheet from the typewriter; while that part of the structure in the rear ofthefront portion is composed of the main flap folded against the inner side of the front portion 10, the inwardly folded ends or gussets, and the pasted'together rear flaps securing the body of the envelope together. 7 In using the combined envelope and. letter sheet the name of the addressee is written on the face ofthe envelope and the letter is written on the front part of the letter sheet from top to bottom of'both envelope and letter sheet in regular order. The letteris then folded on the dotted lines 1? and by opening the envelope as shown in Fig. 1 the folded letter connected to the rear wall 11 may be easily inserted in the envelope, it being noted that the pleated ends or gussets 18a permit the upper end or mouth of the envelope to be opened wide for the insertion of the folded letter. It is now only necessary to fold the flap upon the back of the on velope and attach the-same for sending the etter through the mails, in one instance (Fig. 7) said flap belng inserted under the rear flaps 18 in sending the letter by third-class mail and in the other instance said main flap being pasted over the rear flaps for first-v class mail (Fig. 6). When the envelope is intended for first-class mail only, flaps 18 are pasted to the back of the envelope by means of the gummed edges 24, and of course it will be understood that in this instance, for firstclass mail matter, short rear flaps 18 may be used and pasted directly to the back portion 11, such short flaps being commonly used in the formation of envelopes.
The construction and operation of my improved form of combined envelope and letter sheet will be readily understood from the foregoing description, and it will be apparent that by forming the blank as shown in Fig. 4 of the drawin s the envelope will be provided with'inwardly foldable end pieces or gussetspermitting the mouth of the envelope to be opened widely for convenience in placing the attached folded letter sheet into the envelope, and that the form of the combined envelope and letter sheet (Fig. 5)
facilitates he writing of both the address and letter.
Having thus described my invention, what I claim as new is:
1. A combined envelope and letter sheet tegrally with the gussets and extending across the back portion of the envelope to which they are attached, a letter sheet formed integrally with and extending from the outer end of the back portion of the envelope, and a sealing flap extending outwardly from the outer end of the front portion of the envelope.
2. A blank for a combined envelope and letter sheet formed of a single sheet of material and shaped to provide a rectangular shaped front with a sealing flap at one end thereof, a similarly shaped back portion at the other end of said front portion, a letter sheet extending from the outer end of the back portion and of less width than said back portion, and extensions at opposite sides of the front and back portions shaped to provide triangular shaped foldable gussets at the sides of the front portion and cut away from the back portion to form back flaps for the envelope at one side of said gussets, said back flaps and sealing flaps being provided with gummed edges for sealing the combined envelope and letter sheet when folded upon
