Specification of Letters Patent. Patented J an. 1919.

Application filed November 13, 1915. Serial No. 61,402.

.Middlesex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Envelops, of which the following is a specification, accompanied by drawings forming a part of the same.

The envelop forming the subject of our present invention is designed for inclosures which may require a memorandum thereof upon the envelop itself for permanent preservation, and a corresponding memorandum upon a detachable flap capable of being preserved as an inclosure in the envelop.

It is the object of our invention to provide an envelop having the above named characteristics and capable of being made including the operations of gumming and .folding upon envelop machines now in common use.

Further objects of our invention are to bring the detachable flap into contact with an unfolded side of the envelop in order that the inscription uponthe outer surface of the detachable flap may be transferred to a smooth and unfolded surface by means of an interposed. carbon paper, and also to bring the, inscription u on the detachable flap .and its'carbon duphcate upon the body of the envelop upon the same side of the envelop blank previous to its being folded as in order that any rinted matter, accompanying the inscription may be placed upon the envelop by a single operation.

The above objects we accomplish by the envelop illustrated in the accompanying drawings and hereinafter described, the

novel features beingpointed out in the appended claim.

Referring to the accompanying drawings,

- Figure 1 represents an envelop blank in its extended form showing the shape of the blank previous to folding, the surfaces to which gum is applied, and the lines upon which the blank isto be folded.

Fi 2 shows the completed envelop with the et'achable flap. removed, 'and with the seal flap folded over the-back of the envelop.

Fig. 3 represents the back side of the completed envelop, with the detachable flap removed, and having the seal flap folded side of the envelop.

Fig. 4 represents the front sideof the 'envelop with the. detachable fiapextended to disclose printed matter upon the face. of the envelop.

Fig. 5 represents a front view of the envelop with the detachable flap folded upon the face of the'envelop, showing printed matter upon the detachable'fiap corresponding to similar printed matter upon the face of the envelop, as shown in Fig. 4.-

Fig. 6 represents a sectional view of the envelop with the detachable flap extended in the osition shown'in Fig. 4. Fig. represents a preferred form of car bon sheet for interposing between the detachable flap and the face of the envelop for the purpose of allowing independent memoranda to be inscribed upon the on. I

velop I Similar reference characters refer to simibroken lines 2, 3, {l and 5.forms an unfolded body portion, the outer side of which constitutes the face of the envelop. The rectangular section 8 included between the sides of the blank and the broken lines 3 and 9 forms theback flap of the envelop and is .of the same size as the rectangular body portion 7. The broken line 9 represents a line of perforations separating the back flap 8 from a rectangular portion 10 forming a detachable flap, the length and Width of which is preferably slightly less than the size of the back flap 8, in order to allow the flap when detached to be inserted readily within the envelop.

The blank represented in Fig. 1 is folded as follows :--The first fold 1s upon the broken line 2 turning over the extended portion 11 upon the body portion 7 of the envelop in order to form a seal flap tucked within the envelop, but capable of being withdrawn in order to close the envelop after the detachable flap has been removed. The blank is next folded upon the broken line' 3, turningover the back flap 8 to cover turning over the narrow end flaps '12 and '13, said end flaps being folded with their gummed surfaces 6 in contact with the outer:

.. side of the back flap 8, thereby completing the envelop, its final form being represented n front view in Flg. 4, and in sectional vlew 1n Fig. 6.

-While the blank 1 is in its extended form, we print upon the reverse sides of the body,

portion 7 and the detachable flap 10 corresponding printed matter, said printed matter being arranged upon the face of the envelop to correspond in position with the printed matter upon the detachable flap 10 when the latter is folded down upon the q is transferred by the carbon paper to the face of the envelop, as shownin Fig. 5. This printed matter .will be varied according to the uses to which-the envelops are to be put. In the present instance, the printed matter consists of the broken lines 14 and 15, arrangedfor any desired memorandum, the

date line 16 and adollarrline 17, withbroken' lines 18, 19 and-20 for an address, and a.

supplemental date line 21. Upon the face of the envelop are broken lines corresponding to the lines 14 to 20, inclusive, asjrepresente'd at 14', 15, 16, 17, 18', 19, and 20',

but with the, date line 21 omitted, leaving a space for an additional memorandum as indicated by the broken lines 22.

Our-improved envelop is especially adapted for inclosing deposits for b ank collection to be indicated by a memorandum upon the envelop and having a corresponding detachable memorandum which may be given to de:

positors. Our improved envelop is also especially adapted to facilitate the collec-' tion of coupons upon which an income tax is payable. In such cases the prescribed form of certificate require d'by the internal tax collector may be printed upon the outside of the detachable flap 10, with suitable spaces prepared upon the facex7 for the transfer of the carbon inscription, In order to prevent the transfer of the inscription upon the date line 21 and" to preserve a blank space for the memorandum at 22 on the face of the envelop-,we interpose a sheet 'of carbon paper 23 corresponding substantially to the size of the detachable flap 10,

the detachable flap 10 in the position indicated by the broken line 25, Fig. 4'. The detachable flap is then folded upon themterposed carbon paper and the whole may.

be held securely in place by a small metallic clip over the edge of the envelop. The requisite inscription is then made upon the outer surface of the detachable flap 10 which envelop, the seal flap 11 withdrawn and.

folded over the back of. the envelop. We claim,

'An envelop of the class described, comprising an elongated rectangular body,'an, integral ungummed seal flap extending fromone of the. longer sides of the body,

narrow gummed end flaps extending from each end of the body, a rectangular ungummed back flap of substantially the same size asthe body and having an ungummed extension projecting from the side opposite said seal flap and shorter than the back flap,

said envelop being completed by folding-in the order named, folding the seal flap on'the body of the envelop, folding the back flap over the seal fla and folding the end flaps ap, the face of the envelopand the back of said extension having correover the back sponding' printed matter thereon.
