Tr all whom it may concern Beit known that we, CLARENCE P. rCnam:- BEnLiN and CHESTER T. Fnzznr, citizens of the United States, residing at Detroit, county 5 of Wayne, State of Michigan, have invented Q. `in the art to `which it pertains to make and use the same, reference being had to the f'accompanying drawings, which form a part of this specication.

This invention relates to envelops for 1,5 y1inailing purposes and its object is a double f" .'pompartment envelop for the joint mailing 'et first class and lower class mail matter.

" y/l-leretofore in mailing catalogues or other l.' matter requiring less than' first class postage, 1t has been necessary lto mail such matter separately from a letter referring thereto causing much 4inconvenience as frequently the matter to which the letter pertains is not received until a considerably later time-than With the double envelop here shown, the letter accompanies the lovver class matter and both are received at the same time.

A further object of the invention is an inexpensive envelop for the purpose which may be formed from a single pieceo material.

These objects and the various novel features of construction are hereinafter more fully described and claimed and shown in the accompanying drawings in Which- Figure 1 is a perspective view of the envelop ready for mailing. Fig. 2 is a similar view showing both compartments open.

F ig. 3 shows the blank from which the envelop is formed.

Similar characters refer4 to similar parts throughout the drawings and specification.

The envelop is formed of two separate compartments, the compartment 1 being preferably of comparatively large sizeV to receive catalogues, samples, or other lower class mail matter, While the compartment 2 is to be used for first class mail matter and is practically of the size of an 'ordinary letter-size envelop. lIt is to be understood however that both compartments may be made of any size desired without departing from the spirit of this invention. The compertinent 2 is provided with a gummed flap 3 by means of which it may be sealed and when sealed the compartment 2 may be ifolded down over the 'opening et the coinpartment l providing a closure therefor.

The com artment 1 is preferably provided 1with a den le tongued clasp 1L adapted to be inserted through an aperture 5 formed near the outer edge of the compartment 2 when the envelop is' folded and the clasp tongues are then bent over in the usual manner indicated in Fig. l. This brings the reverse side of the compartment 2 to weit on which is to be placed the address and hrst class postage, as indicated in Fig. l. The reverse side of the compartment 1 is alsoadaptable for :use in addressing on which side is valso to be placed thepostage for the lower class matter.

Both compartments areormed from a single blank of the general form shown in Fig. 3. uThe part 1() of the blankl is irst folded on the dotted line l and is glued to the back of the blank substantially on the dotted line 12. The flap 13 is then folded over the end of the part 10 and the opposite end is provided with the gummed flap 3 heretofore mentioned, by means of which the compartment 2 may be sealed. 'The lower side 'flap 14 is next folded over on the body of the blank along the dotted line l5. T he similar lower side flap 16 is then folded along the dotted line 17 and glued to the first side flap 1d, as is indicated in Figs. land 2. The lower end iiap 18 is then folded over and glued or secured to the bottom ends of the flaps ld and 16 providing a compartment having an open end as indicated at 19 in vFig 2 With an envelop thus formed, catalogues and other samples may be readily inserted in the compartment 1 and a letter relative thereto may be inserted in the compartment 2 and which is then sealed with the gummed flap 3. The compartment 2 is then folded downward over the mouth of the compartment 1 providing a closure therefor that may be held in place with `the clasp Il after the manner now in use with envelope for lower class mail matter.

Having thus briefly described our invention, its utility and mode of construction, what we claim and desire to secure by Let ters Patent of theUniteol States 1. A blank for forming a double compartment envelop comprising a main body portion having two comparatively large side iiaps less in length than the said body and adapted to be folded thcreover, one of said flaps being gummed to secure tbe iaps in folded relation, and o gumnled end flap adopted to be folded over and secured to the ends of the said side flops; said body portion having additional comparatively smell gumnled side fiaps adjacent the first n1entioned side flops and extending approximately half the remaining length of the body portion, the remaining' port of tbe said body portion being gnmnled at the end und adopted to be folded upon itself and secured in place, tbe two smell gumined side iinps being. adapted to be folded over the seid folded body portion and secured thereto.

A double compartment envelop coniposed of a blank formed of n single piece of material having n moin body portion provided with oppositdside flaps less in length than the said body and vadopted to be folded thereover7 one of said flaps being gunnned for attachment to the other to secure the iaps in folded relation,.a gunnned end flop adopted to be folded over and secured to the ends of the said side flaps; said body portion having additional gnmmed side flaps parallel with the first mentioned side flaps and 4the adjacent 'end of tbe body portion being guxmned and being adapted to be folded upon itself and secured in place, said :nlditional gummed side liaps being adapted to be folded over the ends of said folded body portion and secured thereto.

3. A double compartment envelop oomideneee posed of n blank formed oit' a single piece of materiel having n body portion provided with two comparatively large side dans greater in length than half the length of the body portion and adapted to be folded thereover, one of said llaps being gummedlend attaohe'ble to the other to secure the flops in 'folded relation, a gummed end fiap adopted to be folded over and secured to the ends oi tbe said side flaps, the compartmenttnns formed'being open at tbe opposite end, e clasp secured to tbe overlapped portion of saidride flaps; said body portion of tbe blank baring additional comparatively smell i;'uxnmed side lizips adjacent the first inen tioned side flaps and extending npproximately half the remaining length of .the body' portion, the body portion being gnnnned at the end and adapted to be folded upon itself? und secured in place, the folded body portionhaving un aperture at the folded end to receive the clasp when tbev compartments are in folded relation, the 'two small gummed side flaps being adapted 'to be folded loverthe-folded body portion and secured thereto.
