LOOSE-LEAF BINDER.

Application filed March 13, 1920. 7 Serial No.

To all whom it may concern:

Be it known that I, ALBERT IV. ENGEL,

a citizen of the United States, residing at hicago, in the county of Cook and the State of Illinois, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification reference being'had to the accompanying drawings forming a part thereof.

he purpose of this invention is to provide an improved loose-leaf binder, particularly adapted for an album, or in general for holding, as loose leaves, envelopes whose contents may be rendered safely secured by means afforded for tying the cover members in closed position. It consists in the elements and features of construction shown and described, as indicated in the claims.

In the drawings Figure 1 is a perspective view of a loose leaf binder with envelope contents, equipped with the parts constituting this invention, the same being shown partly open-ed and with the opposite ends of the strap and ties which embody the invention disengaged.

Figure 2 is a plan View of the securing strap with its ties disengaged from the cover members of the binder.

Figure 3 is a plan view of one of the binder members detached.

The structure shown in the drawings comprises two similar binder members, each consisting of the binding strip, 1, at one end, and cover boards, 2, hinged thereto at 3. The binder strip has midway in its width a strap slot, 4:, which preferably has the form, seen in the drawings,that is, the middle part of its length being a round eye, 4;, the slot extending both ways from the eye with a width less than the diameter of the eye, for a purpose hereinafter explained. The strap has at the middle portion of its length a series of tie-apertures, 6, and near its end an additional aperture, 7, and preferably a pair of apertures, 7, 7 R-eeved through the apertures of the strap are two ties, 9, 9, each having one end emerging through an end aperture, 7, and the other end emerging at the outer side of the strap through an aperture of the middle ser es, the proximate ends of the two ties emerging from said middle series of apertures at a distance apart substantially that of the thickness of the binder and contents at any Specification of Letters Patent.

given time; that is, so that between the two emerging ends, or between the two apertures of the middle series at which said ends emerge, the distance is suflicient to accommo' date the binder and contents, so that the strap inserted through the strap slot, 4, and emerging at the opposite outer sides from the binder members, may have the ties at the bound end of the binder also emerging at the opposite outer sides of the binding strips at a position to be tied together embracing said bind-er strips at the bound ends, while the opposite end of the ties, emerging through the end aperture, 7, may extend out along the length of the covers and be tied together embracing their free ends, thus securing the binder and its contents against the loss of the latter, it being understood that the particular purpose of thus providing means for tying the binder is that the' bound-in contents or loose leaves may consist of envelopes, 12,-which having their end flaps or side flaps unsealed, for convenience of inserting and removing the contents of the envelopes,are held securely closed by holding their said flaps closed as long as the cover members of the binder are held closed.

The particular purpose of making the slot, 4, with the enlargement constituting the eye, i at the middle part, it may be understood, is to accommodate the ties in entering and and withdrawing the strap with the ties therein, through said slots.

I claim:

1. In a loose-leaf binder, in combination with binder members, each comprising a binding strip at one end and a cover board hinged to the binding strip, the binding strips having each a strap slot extending parallel with the hinge; a strap entered through said slot with its opposite ends emerging at the outer sides of the opposite cover boards, said straps having each a series of tie apertures distributed over the middle part of the length of the strap, and additional apertures near each end, and two ties reeved respectively as to one end through the end apertures of the strap, and extending beyond the ends of the strap toward and beyond the free ends of the cover board, and as to the other ends, reeved through apertures of the middle series and emerging at the outer side of the strap at a distance apart approximately the thickness of the binder and contents; whereby the correspending ends of the ties may be tied to of the length of the slot, the slot running gether embracing the binder at its opposite from the eye in both directions being less in ends. Width then the diameter of the eye; whereby 2. The construction defined in cluim l forethe ties may heziccommodated in entering u going, with the apertures in each end of the and Withdrawing the strap through the slot.

' strap consisting of a pair of tie apertures In testimony whereof, I have hereunto set proximately situated, my hand at Chicago, Illinois, thisfllth day 3. The construction "defined in claim 1 of March,1920. i foregoing, with the strap slots in the hind- 10 ing strips having each an eye at the middle ALBERT W. ENGEL.
