LOOSE LEAF BINDER Filed March 8, 1927 INVENTOR Fovazu [van/c. 8:554, Jk,

Patented Nov. 12, 1929 BOYDEN EUGENE BEEBE, JR, OFBURLINGTON, VERMONT LOOSE-LEAF BINDER Application filed March 8, 1927. Serial 110,173,702.

The present invention relates to improvements in loose leaf binders and its particular object is to provide a loose leaf binder that is very simple in construction, can be made by the most simple means at the disposal of anybody and can be quickly improvised from materials usually at hand in any business or even in most households. It is proposed to utilize for this purpose an ordinary strap or band which is passed through registering perforations in a stack of sheets and which is provided with simple buckles Or fasteners, which may be slid up against the stack from opposite sides for holding the sheets together. It is further proposed to provide in connection with this fastening means a simple cover made in such a manner as to hide the fastening means when applied, while the cover is secured to the stack by the fastening means. 2 It is further proposed to arrange the cover in such a manner that the same may be readily improvised from practically any material at hand and particularly allows any ordinary book cover to be used.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred form of my invention is il lustrated in the accompanying drawing, in which t Figure 1 shows a perspective view of a stack of sheets held together by my fastening means;

Figure 2 a transverse section through the same;

Figure 3 a transverse section through a single arrangement having covers secured to opposite sides of the stack ;and

Figure 4 a detail View of a strap or band used for hinging the leaves and covers together.

While I have shown only the preferred form of the invention, it should be understood that various changes or modifications r may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

In the form shown in Figures 1 and 2 a plurality of sheets 1, which may be single as shown in Figure 2, or double as shown in Figure 1, are placed in stack formation and are, formed with registeringperforations 2 nearone edge thereof, theperforations be ingpreferably elongated to run parallel to the said edge so as to allow the straps or bands 3 to be passed therethrough. The straps may be provided at the ends with suitable stiffening members 4 facilitating the introduction of the same. The perforations 2 preferably communicate with slots 6 leading t'othe adjacent edge of the stack, the slots allowing the band?) to be introduced from the edge, or allowingsuccessive sheets to be introduced between the sheets originally used without necessitating a complete disassemblingof the stack. The, bands ghave fasteners T 'slidable' thereon.

The'member, 7 is shown as a clip formed with a pairof elongated slots 8 and a central rib 9. The band'is guided through the slots. It will be seen from Figures 2 and 3 that the members 7 fulcrum on one of their edges and that force applied to move them on the bands will first swing the fulcrumed edge, and this will cause the opposite side to clamp the'band 3 between it and the book. The greater the force exerted, the greater the clamping ac- I tion; In thisway accidental movement of theimembers is prevented; Instead of the fastener 7 I may use the well-known buckles 11,presenting points 12 adapted to penetrate intothe material of the band at any place desired. r I

It will readilybe seen that the construction. shown in Figures land 2 is of the simplest kind, merely requiring the assembling of the sheets in stacked relation, passing the j bands through the, registering perforations and causing the fasteners to bear on the stack from opposite sides thereof.

The form shown in Figure 3 adds the covers 13 comprising ordinary sheets of heavy material and having wings 14 hinged to one edge thereof, as shown at 16, the hinge preferably comprising a connecting piece of flexible material, leaving a certain amount of a space between the wing and the sheet 13, when the former is folded upon the latter. The wings are provided with perforations 17 registering with those of the stack, and the band "movable thereon for clamping the sheets 3 is guided through the wings in the manner illustrated in Figure 3, the fastening means 7 being made to bear upon the wings from the outside, while the sheets 13, when folded upon the wings in the manner illustrated in Figure 3 completely hide the fastening means from view.

It should be understood that in the form shown in Figures 1 and 2 the outside sheets of the stack may be made heavier to form covers. In this latter case the band may pass,

throu h the slots in the cover to partially conceal t e same.

I claim:

1. A loose leaf binder comprising a plurality of sheets having aligned perforations therein, a binding member extending through said aligned perforations, and an adjustable fastening member disposed on the binding member at each side of the sheets and being therebetween, each fastening member being adapted to clamp the adjacent portion of the free end of the binding member to the sheets ,when the sheets tend to separate at their bound edges.

2. A loose leaf binder comprising a plurality of sheets having aligned perforations therein, a flexible binding member extending through said aligned perforations, and an ad'- justable fastening member disposed on the binding member at each side of the sheets,

and being movable thereon for clamping the sheets therebetween, each fastening member being adaptedto clamp the adjacent portion of the free end of the binding member to the sheets when the sheets tend to separate at their bound edges.

3. A loose leaf binder comprising a plurality of sheets having aligned perforations therein, a flexible binding member extending through said aligned perforations, and an adjustable fastening member disposed on the binding member at each side of the sheets and being movable thereon for clamping the sheets therebetween, each fastening member having one of its edges fulcrumed against the sheets, the opposite edges thereof normally being spaced from the sheets, whereby each fastening member is adapted to clamp the adjacent portion of the free end of thebindingmember to the sheets when the sheets tend to separate at their bound edges.
