6 Claims.

This invention relates to loose-leaf binders of the type used as record books for the recording of documents such as deeds, mortgages, assignments, etc.

The invention has as an object a loose-leaf binder structure which is particularly rugged and durable and which will, to a great extent, withstand the ravages of fire and flood without permanent damage, and which affords maximum protection to the leaves. More particularly, substantially the entire structure of the book is formed of corrosion resisting material, such as aluminum and, While possessing the advantageous characteristics herein referred to, is of less weight than such binders embodying conventional construction.

A further and important object of the invention resides in a structure of the type alluded to which possesses certain economical factors contributing to low manufacturing costs and which embodies an arrangement by which the structure of the book can be quickly and conveniently changed to incorporate or eliminate certain features as desired. For example, the leaf impaling means is readily detachable from the back member of the binder, permitting different forms of leaf impaling mechanism to be used in the binder, such change being accomplished Without the aid of any special tools whereby the jobber or dealer can conveniently assemble the binder incorporating the particular features desired by the customer.

The invention has as a further object a looseleaf binder structure wherein the back member, leaf impaling means and covers are formed of metal, and which structure incorporates surfaces formed of fibrous material on which printing, legends, or descriptive matter, may be applied, the arrangement being such as to enhance the attractiveness of the binder and to simulate binders of conventional structure covered with leather,

or other facing material.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a perspective view of a loose-leaf binder embodying the structure of our invention.

Figure 4 is a lengthwise sectional view of the back member structure and a contiguous portion of a cover in plan view.

Figure 5 is an exploded view of the elements or members illustrating the arrangement of the assembly to form the back member of the binder and including contiguous portions of the covers.

Our binder consists generally of a back member, covers hinged to the back member, and leaf impaling means detachably secured to the back member. As will be apparent hereinafter, the invention resides particularly in the novel structure of the back member and cover. Any suitable leaf impaling means may be employed.

The back member consists of an outer member Ill of general trough-shaped formation provided with hinge eyes ll arranged in spaced relation along each edge thereof. This outer member I0 is formed of sheet metal of light weight and having comparatively great tensile strength, such as aluminum, and the member may be conveniently pressed or drawn from a flat sheet, and the ends are preferably rolled or crimped inwardly as at l3 to form finished end edges. The back member of the binder also includes a fiat member which may take the form of a plurality of individual straps l4, or a continuous plate extending transversely across the open side of the trough-shaped member I!) and being provided on opposite edges with hinge eyes IS. The arrangement is such that when the straps M are assembled on the member [0, the hinge eyes l5 are in axial alinement with the hinge eyes II, and the flat members M are detachably secured to the member [0 by pintle rods [6 extending through the hinge eyes H and [5.

The binder includes front and rear covers ll, each of which consists of a shell formed from sheet metal and including a main panel it having a rearwardly extending portion l9 formed with spaced hinge eyes 20 arranged intermediate the hinge eyes I l and I5 and being pivotally mounted upon the pivot pins IS.

The covers further include a filler member 2| of heavy cardboard, or like material, arranged on the inner side of the shell and with the marginal edges tapered, as illustrated in Figure 3. The marginal portion of the shell is formed on a complemental taper 22, and the top, bottom and front edges thereof bent inwardly to form inwardly extending flanges 23 overlapping the marginal portion of the filler 2| on the inner side thereof and serving to retain the filler in the shell. A liner 24, of substantially the same thickness as the sheet metal from which the shell is formed, is secured openings ii].

to the inner side of the filler 2| within the flanges 23 by means of adhesive or the like, and a finishing layer 25 of paper, or like material, is secured to the inner side of the cover to effect a proper finished appearance for the same.

The leaf impaling means is secured to the fiat members l4, and is here shown in the nature of a plate 26 secured to the members I4 as by rivets 21. The plate is substantially the length of the binder and extends transversely of the back member and is provided Withhinge eyes 3!] arranged in spaced relation along each edge thereof. The leaves are arranged upon a plurality of leaf impaling posts 3|, the ends of which extend into and are detachably secured to housings 32 likewise provided with hinge eyes 33 and pivotally secured to the eyes of plate 2% by a pintle rod 34. The leaf impaling means shown is similar to that disclosed in Cooper Patent No.

2,067,846, and includes a slide bar 35 arranged L is carried by the flat member l4, one leaf impaling means may be substituted for another by simply removing the pintle rods 5.

The back of the binder is usually provided with certain legends designating the subject matter of the instruments recorded in the binder, the number of the book, and the date or dates covered by the instruments recorded, as illustrated in Figure 1. These legends may be applied at the plant where the binder is manufactured, but usually the legends are applied to the binder by a local dealer by means of printing the legends on the exterior surface of the back member. In order to facilitate the application of the legends by the local dealer, the member H] is provided with one or more openings 4d, and the back member of the binder includes an intermediate member ll formed with a convex portion complemental with the concave inner surface of the outer member Hi, and may be formed of suitable material, to fill the space between the flat plate member I4 and the outer member It] When leaf impaling means of the type shown is employed in the binder. As here shown, the intermediate member 3| is formed of sheet metal and as being complemental in general form to the outer trough-shaped member l8, and being provided at each edge with surfaces 42 engaging the members M, and with one or more of the surfaces 42 provided with prongs 43 engaging the sides of the members M, whereby the members l4 retain the intermediate member 4| from movement relative to the outer member Ill.

The openings 45] give the back member a paneled appearance simulating the design of the back member of conventional binders now in use. With this structure, the legends may be applied to or embossed in the intermediate member 4| and so arranged as to register with the However, these legends are usually applied to the binders by local dealers and the apparatus for this purpose is, of course, particularly adapted for printing upon the leather covered back members of conventional binders. To further enhance the appearance of our binder, and to more closely simulate the conventional leather covered binder, and to also avoid the necessity of dealers acquiring special apparatus for applying the legends to metal surfaces, or embossing apparatus, we prefer to include alegend strip 45 preferably of fibrous material, such as leather, which strip is inserted between the outer member l0 and the intermediate member 4|, and which strip may be provided with raised surfaces 46 arranged, in register with the openings 4!] of the outer trough-shaped member Iii, the strip being pressed against the latter and held in place by the intermediate member 4|. This arrangement adds to the appearance of the binder and closely simulates the paneled effect of the conventional binder now in use. Due to the fact that the strip 45, or the raised surfaces 46 thereof, are formed of leather, the printing apparatus now used by jobbers, dealers and cus- 1 tomers, may be used to apply the legends t0 the binders as they go into use.

The outer member I'll and the metallic cover shells may be provided with a colored crackled finish which very closely simulates the appearance of grained leather, whereby the entire binder matches conventional binders now in use in general appearance.

The binder is particularly economical to manufacture in that all of the metallic parts are conveniently formed or drawn upon a press, and the binder is particularly durable and rugged and is not of greater weight than binders of conventional structure. These features are of particular importance in View of the fact that record books are continually consulted over a long period of years by search clerks and the like, and accordingly receive a great deal of usage and rough handling.

It will also be observed that the binder is :i quickly and conveniently disassembled by simply removing the two pintle rods 20. This permits the local dealer to reassemble the binder with any particular leaf impaling mechanism desired by a customer. Also, this permits removal of the legend strip 45 for convenient printing.

It will be apparent that many of the functional features of our binder may be retained if the outer back member I9 is formed solid or Without openings, and the legends, which are illustrated in Figure 1 as being applied to the legend strip 46, may be placed or embossed directly on the outer back member in.
