LOOSE-LEAF ENVELOP-ALBUM.

Application filed March 13, 1920. Serial No.

To all whom t may concern.'

Be it known that I, ALBERT lll. ENGEL, a citizen of the United States, residing at Chicago, in the county of Cook and the State of Illinois, have invented certain new and useful Improvements in Loose-Leaf Envelop- Albums, of which the following is a specification, reference being had to the accomppanying drawings, forming a part thereon The purpose of this invention 1s to provide an improved form of loose-leaf album, of which the loose or disengageable and removable leaves are in the form of envelope for containing pictures and the like, and adapted for the insertion of the contents of the envelops and for safe securement of the same therein by closure of the binder. It consists in the elements and features of construct-ion shown andl described as indicated in the claim.

In the drawings:-

Figure l is a perspective view of the loose-leaf binder of which the loose leaves are envelope.

Fig. 2 is a and showing therein, also velop.

F ig. 3 is a dissected longitudinal section showing a single envelop between the partly opened covers.

Fig. l is a similar transverse section showing the envelop partly open between the partly opened covers.

The structure shown in the drawings comprises separable covers of a loose-leaf binder, cach consisting of a binding` strip, l, and a cover board, 2, hinged thereto as seen at 3, any means of clamping or tying the cover plan view of the binder open, one of the loose leaf envelope open, and contents 1n said enmembers together beine contemplated andl no specic means being shown, except as indicated by eyelets in the envelops and in the binding strips of the cover member, through which any form of fastening' may be inserted. rlhe characteristic of the invention is in the form of the envelop which constitutes a loose leaf, said envelop being formed with the back or main panel, et, extended beyond. the side flaps, the side flaps and one end flap being adapted to be folded upon Specification of Letters Patent.

the back or main panel in the usual manner, so as to close the envelopl at the three edges having such llaps, whereby the open edge of the envelop is the inner end at which the envelop is secured by the extended back panel between thev binding strips of the binder. The purpose and the result of this construction, it will be understood, is to cause the only opening` through which the contents of the envelop might escape to be at said inner bound end where escape is rendered impossible by the closing of the binder.

Specifically end,-that is,

it is desirable that the outer the end opposite the bound end should be permanently closed by sealing the Hap at that end onto one of the side flaps, 7, the other side flap 8 being left unsealed to afford opening for inserting contents through that side of the envelop. For the purpose of easy entrance of pictures and like material into the envelop, it is desirable to cut away the edge of the side Hap, 7, on an oblique line from the outer open corner toward the inner open end of the envelop as seen at 7a.

.Any suitable means may be employed for holding the binder closed, as by an elastic band, l0.

I claim A loose-leaf album consisting' of the combination with separable cover members, of envelops having one end without a flap and the back or main panel at that end extending for engagement between the cover members of the binder, and having' flaps for closing all the other edges; whereby the enveloped contents are secured against escape by the closing of the binder, manently closed at the end opposite that which is engaged between the tongue members and at one side by sealing the flap which closes said end onto one of the side flaps, the other side flap being unsealed for easy entrance of the contents into the envelop when the binder is open.

In testimony whereof I have hereunto set my hand at Chicago, Illinois, this 11th day of lllarch, 1920.

ALBERT W. ENGEL.
