Patented Apr. 6, 1937 UNITED STATES LOOSE LEAF BINDER George H. Dawson, Chicago, 111., assignor to Wilson-Jones Company, Chicago, 111., a

corporation of Massachusetts Application October 8, 1934, Serial No. 747,274

2 Claims.

This invention relates to a loose leaf binder and more particularly to means for hinging a pair of separate cover members to a back member.

It is an object of this invention to provide an attractive and durable metal hinge for loose leaf binders that will not have any raw ends exposed. It is a further object of this invention to provide a metal hinge that will be protected by the back of the binder. Other objects of this invention will become apparent upon reading the following description taken in conjunction with the accompanying drawing, in which- Figure 1 is a perspective view of a loose leaf binder embodying my invention, Figure 2 is a cross sectional view taken along the line II-II of Figure 1; and

Figure 3 is a top plan view of one corner of the binder with a portion broken away to facilitate illustration of the structure.

In the drawing, the reference numeral 2 indicates a back member which includes a back plate 3 of metal, fiber or any suitable material. The entire outer exposed surface of the plate is covered by a sheet 4, of leather, fabric, or other suitable material, which has its edges turned in under the plate 3, as indicated at 5. A conventional ring metal 6 is secured to the back plate 3 by means of rivets I, or in any other suitable manner.

A strip 8 of metal, leather, fiber, or any other suitable material is permanently secured between the plate 3 and the bottom of the ring metal. The outer edges of the strip 8 are spaced from the edges of the back plate 3 and are provided with a plurality of relatively small apertures 9 spaced equidistantly from each other. The binder includes cover members H), II, which are each provided with apertures I2 similar to the apertures 9 both in size and spacing.

The covers are hinged to the back member by means of a helically coiled wire [3 threaded through the apertures 9 and I2. The pitch of the helix is equivalent to the distance between adjacent apertures. The ends [4 of each wire l3 are positioned between the back plate 3 and the strip 8 to conceal the ends and to provide a smooth finish. Although the clamping action between the plate 3 and the strip 8 is sufiicient to prevent displacement of the ends M of the wire, the ends I 4 of the wire coil may be looped betweerf two turns of the wire for greater security. As 5 shown in Figure 2, the edges of the back plate 3 project slightly beyond the outer extremities of the hinge members, so that when the binder is placed on a desk or other highly polished surface, the edge of the back plate engages the surface and the wire coil cannot scratch or otherwise mar the surface.

Although I have described a preferred embodiment of my invention in considerable detail it will be understood that the description thereof 15 is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to be restricted to the exact construction described, except as 20 limited by the appended claims.

I claim:

1. In a loose leaf binder, a back plate, a ring metal secured to said back plate, a metal strip secured between said ring metal and said back plate with its edges spaced from the edges of said back plate, the edges of said metal strip being perforated by a series of equidistant apertures, a cover member provided with similarly spaced apertures, and a helically coiled wire threaded through both series of apertures to hinge said cover to said metal strip, the ends of said wire being concealed between saidmetal strip and said back plate,

2. In a loose leaf binder, a back plate, a ring metal secured to said back plate, a metal strip secured between said ring metal and said back plate, the edges of said metal strip being spaced from the edges of said back plate, a cover member, and a helically coiled wire hinging said L10 cover to said metal strip, said back plate projecting beyond the outer edge of said helically coiled wire to prevent said wire from marring any surface upon which the binder may be handled.
