2 Claims.

vide a back-binder that will constitute an easel for its associated booklet sheets and/or cooperate with a top cover member to provide a closed booklet um't suitable for mailing.

Other features, objects and advantages of my invention will appear from the following detailed description wherein reference is made to the accompanying sheet of drawings in which:

Fig. l is a perspective view, of the front from above, of a booklet wherein the back-binder will cooperate with the booklet front either to provide a closed booklet unit suitable for mailing; or to provide an easel for the booklet sheets, this view depicting how the back-binder cooperates with the booklet to provide the closed mailing unit;

Fig. 2 is a perspective view, from the rear and to one side of the booklet, showing the lower flap of the back binder as it appears prior to the with a pair of integral spaced apart parallel elongated tabs 45. i

The tabs 45 are shown as being of uniform width throughout their lengths and each tab extremity is provided in its longitudinal edges with and 43, the eared extremities of the tabs 45 are booklet front being turned on the wide band Fig. 4 is a top plan view of the booklet parts v as they appear when the back of the booklet occupies the same horizontal plane as the booklet sheet that normally lies immediately adjacent to it, this view showing one of the wide band rings of the back-binder having a portion thereof broken away; I I

Fig. 5 is a vertical section-taken on the. plane of the lines 9-9 of Fig. 6 and looking in the direction indicated by the arrows;

Fig. 6 is a fragmentary view illustrating juxtaposed portions of the back-binder and booklet front as they appear before bein assembled with intervening booklet sheets (not shown) or each other.

l Similar characters ofreference refer to similar 7 parts throughout the several views.

In Figs. 1 mi, inclusive, a back-binder of a booklet is depictedat 40, the booklet cover at 4!, and the intervening booklet sheets at 42. i

' Each of the sheets 42 is provided near its upper edge with the spaced apart horizontally elongated slots 43 and the cover 4| is provided with corresponding slots 44 adapted to align with those of-sheets 42. Y

The back-binder 40, being formed of suitable paper stock or other non-metallic bendable material, in sheet form, is provided at its upper end integral tab 5i and that front 4! is provided'between its longitudinal edges and near its lower or unhinged edge with a slit 52that is parallel with such last-mentionededge.

when it is desired th'at the back-binder shall cooperate with the front 4! to convert the booklet into a closed mailing unit, the tab 4i is passed around the adjacent ends of the sheets 42 and front 4| and is-extended through slit 5i from the outer surface of the front as illustrated in Fig. 1.

When it is desired that back-binder 40 shall cooperate with the booklet front 4! to constitute an easel for the leaves s2, the front 4| is swung on rings 48 to lie behind the back-binder 40. Then the talb 5l is passed through the slit 52 to be frictionally held by the boundaries of the latter at any preierred position to which such tab may be adjusted, all this being illustrated in Fig. 3.

Booklets of the kind shown in Figs. 1 to 6 find great usefulness in mailing and exhibiting photographic prints (a fragment of such a print being shown in. Fig. 4)

Having thus illustrated and described several preferred'embodiments of my invention, what I portion that cooperates with the rings, and a relatively wide two-purpose tab projecting from that edge of the back that is most remote from its edge carrying the ring members, said two-purpose tab being adapted to fold over and cover a large portion of the edge of said front most remote from said ring members and to project inwardly through said two-purpose slit so that the end of said tab is covered and protected by said front to convert the back, front and'intervening booklet sheets into a closed mailing unit, said two-purpose tab also being adapted to project in the opposite direction through said two-purpose slit to convert the booklet back and booklet front into an easel forthe booklet sheets.

2. In combination, a booklet back and booklet sheet or sheets and a booklet front hingedly connected at corresponding edge portions in such manner that the sheet or sheets may lie between the back and front or the back may lie between the front and the sheet or sheets, a two-purpose slit formed in the front and substantially spaced from the edge portion of the front that is hingedly connected with the back and the sheet or sheets, and a two-purpose tab projecting from the back at an edge thereof remote from the edge thereof that is hingedly connected with the front and the sheet or sheets, said two-purpose tab being adapted to fold over the edge of said front remote from the hinged edge thereof and to project in one direction through said two-purpose slit to convert the back, front and intervening sheet or sheets into a closed unit having the normally projecting end portion of said tab covered by said front, said two-purpose tab also beingadapted to project in the opposite direction through said two-purpose slit to convert the back and front into an easel for the sheet or sheets.
