COMBINATION EIJVIELOPE AND LETTER Application filed. August 7, 192%.

To aZZ whom it may concern:

Be it known that T, Gnouen Maoirovann, a citizen of Czechoslovakia, residing at Johnstown, in the county of Oambria and State of Pennsylvania, have invented certain new and useful Improvements in Combination Envelopes and Letter Sheets, of which the following is a specification.

This invention relates to new and useful improvements in combination envelopes and letter sheets.

The primary object of this invention is to provide a combination envelope and letter sheet for the purpose of reducing the amount of paper used for corresponding by mail- A further object of the invention is to provide improved forms of looking or sealing means for the above mentioned device.

Other objects and advantages of the '1- vention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 illustrates a plan view of one form of combination envelope and letter sheet embodying this invention,

Figure 2 illustrates a plan view of the structure shown in Fi r. 1 with the letter sheet folded and locked,

Figure 3 shows a plan view of the struc ture illustrated in Figs. 1 and 2 after the letter sheet has been folded against the front wall of the envelope and one side flap of the latter folded inwardly against the letter sheet,

Figure 1 shows a plan view of the structure illustrated in the former figures with the letter sheet folded against the front wall of the envelope, the end flaps of the envelope folded against the letter sheet, and the sealing flap of the envelope folded downwardly into its closing position with the tongues carried by the end flaps inserted through slots formed in the sealing flap, the tongues being illustrated prior to being folded into engagement with the envelope for being sealed thereto,

Figure 5 illustrates a similar v1ew to Fig. 41-, but shows the sealing tongues sealed to the envelope,-

Figure 6 illustrates a plan view of a modified form of combination letter sheet and envelope, and

Serial No. 730,643.

Figure illustrates the form of combination letter sheet and envelope illustrated in Fig. 6 a fter the letter sheet has been folded and sealed within the envelope.

In the drawing, wherein for the purpose of illustration is shown the preferred embediment of this invention, and particularly in Figs. 1 to 5 inclusive, the numeral 5 designates the letter sheet which has formed therein, in close proximity to the transverse edge 6, the slots 7 which extend in parallelism with said edge. The opposite transverse edge 8 of this letter sh et is provided with the laterally projecting sealing tongues 9 that are arranged in longitudinal alinement with the slots 7.

The envelope attached to the letter sheet 5, at the folding line a, consists of a front wall 10 which has attached to its opposite transverse edges the end flaps 11 and 12' which are of substantially triangular shape and have attached to their outer ends the sealing

tongues

13 and 14 respectively. The free longitudinal edge of the front wall 10 has integrally formed therewith the sealing flap 15 which is provided with the sealing tongue 16. This flap 15 is further provided with the angularly arranged slots 17.

It will be noted that the

edges

18, 19, 20, 21, 22 and 28 of the

flaps

11, 12 and 15 are gummed for the purpose of sealing the envelope to confine the letter sheet therein.

The user of this combination letter sheet and envelope may write upon the inner faces of the letter sheet 5 and the front wall 10 of the envelope. After the message has been written, the letter sheet 5 should be folded upon the parallel lines -Z)- and -c for placing the transverse edges 6 and 8 in close proximity to each other, as illustrated in Fig. 2. The tongues 9 should then be inserted through the slots 7 and folded back upon the letter sheet for being sealed thereto as illustrated in Fig. 2. The letter sheet should then be folded upon the line d for forming the same into a rectangle of substantially equal size to the front wall 10 of the envelope. This letter sheet should then be folded on the line a for moving it into flush engagement with the front wall 10.

In Fig. 3 the letter sheet 5 is illustrated as having been folded against the front wall 10. This figure also shows the end fla 11 folded upon the line -e-- so that it Wi l he in engagement with the outer face of the folded letter sheet. The second end flap 12 should then be folded inwardly on line f as illustrated in Figs. 4 and 5. It will now be seen that the sealing

tongues

18 and 14, carried by the

end flaps

11 and 12, cross each other and are inserted through the flaps 17 formed in the sealing lap 1.5. These tongues 13 and 14- are gummed on their rear faces for being folded to overlie the sealing tongue 16 on the sealing flap 15, after the latter has been folded upon the line g, for aiding the tongue 16 in maintaining the envelope in its closed condition.

In Figs; 6 and 7 there isshown' a modified form of combination letter sheet and envelope which includes the letter sheet 5" having attached thereto the front wall 10 of the envelope, as best illustrated in Fig. 6. This front wall 10 also carries the

end flaps

11 and 12 and the sealing flap 15 having the sealing tongue 16*. This letter sheet is intended to first be folded upon the lines b and c and then upon the lines -cl and a, as described in connection with the form illustrated in Figs. 1 to 5 inclusive, for positioning the folded letter sheet in engagement with the front wall 10 of the envelope. The

end flaps

11 and 12 should then be folded upon the lines eand and the sealing flap 15 should then be folded upon the line g for forming the envelope that encloses the folded letter sheet. Thegummed edges of the flaps 1.1 12, and 15 are intended to be sealed to this folded letter sheet for maintaining the combination structure in the condition illustrated in Fig. 7.

It is now believed that the construction and operation of the forms of the invention illustrated in the accompanying drawing and described above will be clearly understood by those skilled in the art and that no further explanation is deemed necesary.

t is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, 1 claim In a combined letter sheet and envelope, :1 letter sheet blank of rectangular formation, foldable upon lines to provide a central portion and side extensions, one of the side extensions having a slot at the upper and lower ends thereof adjacent the outer edge, sealing tongues projecting outwardly of the et ge of the other side extension and transversely alined with the slots to be received therein when the side extensions are folded inwardly to overlie the central portion, the envelope embodying a wall projecting upwardly from the letter sheet blank intermediate the side extensions and alined with the central portion, gummed triangular side flaps on the envelope wall, sealing tongues projecting outwardly from the upper edge of the side flaps, a guinmed closure flap on the envelope wall and said closure flap having relatively angular slots each to receive a sealing tongue on the adjacent side flap.

In testimony whereof I aflix my signature.
