Patented Slept. 15, 1931 UNITED STATES THOMAS MITFORD MOORE, F TORONTO, ONTARIO, CANADA THREE WAY ENVELOPE Application med october so, '1928.

My invention relates to improvements in three way envelopes, and the object of my invention is to devise an envelope which may be used three times instead of once as in the case of an ordinary envelope or three times instead of twice as in the case of an ordinary return envelope without being mutilated in any way, leaving the interior surfaces of the gummed surface on the envelope is required as opposed'to two or more gummed surfaces on ordinary return envelopes, all as hereinafter' more particularly described.

Fig. 1 is a plan view of the envelope opened out.

the envelope when it is being sent for the first time.

Figs. 3 and 4 are the second and third steps respectively. Fig. 5 represents the irst step in folding 3o the envelope when it is being returned to the-sender. f

Figs. 6 and 7 are the second and third steps respectively. 'o p Fig. 8 represents the first step in folding the envelope when it is being sent again to the person to whom it was addressed in theV vfirst place.

Figs. 9 and 10 are the second and third steps respectively.

In the drawings like characteristics of reference indicate corresponding parts in each figure.

1 is the main body portion of the envelope. 2 and 2x the side flaps. 3 is the top la'p of the envelope which is not quite as high as the main body portion and has -a gummed portion 4 along the longitudinal edge separated by a perforated line 7. The senders return address is printed or otherwise placed on the back of said flap. 5 is the botom flap yover the bottom Hap and seal with a stamp Serial No. 315,962.

of the envelope which, is not as large as the main body portion of the envelope, and is preferably cut with a curved edge extending from end to end and terminating at the ends of the portion 1 so that there will be no corners and a postage stamp 6 may beused for sealing purposes in connection therewith as shown in Fig. 4, the ap 5 having the sending address placed upon its back.

Vhen the envelope is to be used it is opened out as shown in Fig..1. The sender being the first person to use the envelope, if it is to be unsealed, folds down the top flap 3 as shown in Fig. 2. The flaps 2x and 2 are next folded over, then the bottom Hap 5, having any sending address placed upon its back, is folded over the end flaps, exposingthe address on the outside of the envelope, asin Fig. 4. It is not necessary to seal t isiap 5 because being neither the same size or shape as the body 1 of the envelope or of the end aps, a portion of the underlying part remains uncovered and" a postage stamp placed as indicated at 6 Fig. 2 illustrates the first step in folding to adhere to the bottom Hap and to one or both of the underlying end flaps serves to efectively close the envelope for mailing. If the sender desires to seal the envelope he may first fold in the end flaps, then fold the top' flap thereover without sealing same, then Afold placed to extend overy the edge of the bottom llhen the person to whom the envelope is addressed receives it, he opens it by breaking the stamp. Then having read the information printed on the inside of the envelope or containedl therein, he places the cheque or note on the main body portion, and then refold the envelope as indicated n Figs. 5, 6 and 7, utilizing the gummed surface 4 in sealing. 90 The envelope is. then opened by breaking the Hap 3 along the line of perforation 7, avoiding tearing the main body of the top flap 3. If it be desirable-to return a receipt to the party remitting, the envelope is folded as indicated in Figures 8, 9 and 10 and a postage stamp applied as shown seals the envelope, or if sealing is not necessary the flap 3 may be folded in first and covered by the end flaps 100 V'als andthe cured by a stamp.

The envelope as described is extremely i simple to make, requiring but one sealing surface while the method of addressing, folding and sealing allow it to take the place of three envelopes and an enclosure such as are used in customary routine, providing also by this method of folding the option of mailing the missive sealed or unsealed thus allowing' forfconsiderable saving in postage as well as labor and material.` It provides, in addiv tion at all times, a perfectly flat, plain back` which may be utilized as an advertising medium. v

What I claim as my invention is l 1. A three way envelope comprising a. paper sheet having a top flap folded inwardly and having a return address space on the back thereof, a pair of end flaps folded inywardly to overlap each other and overlying the top iap, a bottom flap to receive the primary addressfolded to cover a portion onlyof the overlapping portions of said end flaps, and a seal separably connecting said bottom and end flaps leaving the envelope unsealed.

2. three way envelope comprising a paper sheet having a top flap folded inwardly and formed with a separable strip gummed on the inside, said Hap having a return addressspace on the back, a pair of vend flaps folded inwardlyand overlapping each other at the ends, an,l ungummed bottom fla folded to cover a portion only of the over apping portions of the end aps, and a seal separably connecting said bottom and end flaps leaving the envelope unsealed;

3a three way envelope comprising a paper sheet having a rectangular message y space, a top flap adapted to fold inwardly over said message space and havin a return address on its outward side, a pair ofend flaps adapted to fold over and com letely cover said message space on said top ap, a bottom ap of lesser area than said overlapping end liaps adapted to fold thereover leaving a portion thereof uncovered and having an address space on the outer side, and separate means for sealing said bottom flap to secure the p envelope sealed or unsealed.

4. A three way envelope as claimed in' claim 1 in which the top Hap is ada ted to be folded over the infolded end and ottoni flaps and sealed to the bottom flap to form a sealed envelp.
