J. W. YOUNG LOOSE LEAF BINDER Filed July 10, 1935 Wes/e John II. III III IL aw Y E Patented. Dec. c, 1938 UNITED STATES PATENT OFFICE LOOSE LEAF BINDER .lohn Wesley Young, Jamaica, N. Y.- Application July it, 1935; Serial No. 30,648
' '2 Claims. (01. 129-1).
This invention relates generally to loose leaf vision of structure whereby a plurality of indiof this disclosure and as vidual sheets are retained in pad form, and,
firmly held against accidental disengagement, yet the device permits of such easy loading and unloading that it is highly practicable for use in the large scale production of books and catalogues, etc. v
Another object of this invention lies in the production of an article of the class described which is inexpensive to manufacture because of simplicity of the structure thereof, and the consequent low cost of dies and assembling operations.
While this loose leaf binder is light, neat, com-= pact and sturdy, and intended primarily for in-' frequent changing or the bound sheets it nevertheless permits of more frequent changes of the bound sheets where this is found desirable.
A still further object of this invention is to provide a loose leaf binder which presents the trim appearance of a permanent binder and allows the book to lie fiat when opened. This trim and good looking appearance permits the first and last sheets of the bound material to be of leatherette or slightly heavier in weight than the rest of the sheets and thereby form covers for the book, without the need for any external cover.
These objects, and further incidental ends and advantages will more ifully appear in the progress pointed out in the ap pended claims. I
The accompanying drawing shows a preferred form of the present invention in which corresponding reference characters designate correspending parts throughout the several views thereof.
Figure 1 is a transverse sectional view of the device with the binding element carrying a pad of sheets and in engagement with the back plate.
Figure 2 is an enlarged fragmentary view in perspective of the channelled back plate.
Figure 3 is an enlarged fragmentary view in perspective of the binding element.
Figure 4 is an enlarged fragmentary view in side elevation showing the'binding element engaged by the channelled back plate as seen from one side thereof. 1 V
Figure 5 is view similar to Figure 4 but seen from .another side thereof.
Figure 6 is a sectional view of Figure 4 along the line 6-6 thereof.
Broadly speaking, the invention contemplates;
a binding element comprised by a pluralityof co-axially aligned circularly bent'bands, inter are spaced to correspond with the spacing of the circularly bent bands l2 along the longitudinal bar it. l
The bands l2 form less than a complete circle and at the terminals thereof are outwardly obtusely ofiset to form integral tongues it and i5.
Tongue it, since it is formed from the bands l2 and the bar it thereat, constitutes one longitudinal member, whereas the tongues it are disconnected, there being one for each band it.
The channelled back plate it is provided with two longitudinal flanges il and it ctr-extensive therewith. Flanges Ill! and it are acutely bent with relation to theupper face of back plate it (as seen in Figures 1 and 6) and serve to frictionally engage and retain therewithin the tongues it and iii respectively. as indicated at it and iii the outer ends of flanges it and it at either one or both ends of plate is are divergently spread or splayed to form a wider channel thereat to iacilitate the insertion of the binding element by gently easing the introduction of the first-entering edges of tongues Ml and it,
' The width of the back plate it with relation to the diameter of the circularly bent hands it? may be varied to accommodate different thicknesses of the pad it without affecting the efficacy of the device, but for more purposes the said Width and The outer or under surface of plate l6 being plane oilers anideal surface upon which to'impress printed matter such as titles, or the name of the nrm issuing the catalogue, and this operation may be conveniently performed at the time this element is stamped out.
As is apparent to those versed in the art, the plate It may be riveted or eyeletted to an external or auxiliary cover, in which case plate I acts as a support for both element.
The width (incontradistinction to the diameter) of the bands I! and the spacing therebetween is governed largely by considerations of page size, as for example in a book of four inch by nve inch page size, bands one-quarter inch wide, with one-quarter inch spacing have been found satisfactory.
Since this binder is especially adapted for large editions of books, catalogues, etc., it is extremely inexpensive to load. The sheets, having been punched as described, are laid on the edge of a table, and with the channelled back plate I. of the binder slid oil, the tongues H are simultaneously inserted into the several punched the cover and the binding openings ll. Replacement of the back plate II by sliding it into place completes the assembly.
As described above, plate I6 may have spread apart portions l9 and 20 at one or both ends.
. Where the spread apart portions are provided at both ends the plate may be slid into the binding element from either direction with equal facility.
It is distinctly understood that minor. changes and variations in the materials, structure and/or integration of this invention may be resorted to without departing from the spirit of the invention or the scope of the appended claims.
1. A loose leaf binder formed from sheet metal and comprising a longitudinally-extending side bar provided on its inner edge with integral outwardly-extending bands, said bar also being provided on its outer edge with an integral outwardly-extending tongue, said bands being provided on their outer ends with outwardly-extending tongues, and a channeled plate engaged over said tongues.
2. A loose leaf binder comprising a binding element including spaced bands, said bands provided at their inner ends with an integral bar at only one side of said binding element, said bar being provided along its entire outer edge with an outwardly-extending tongue, said bands provided at their outer ends with outwardly-extending tongues, said tongues all having their outer'edges in the same plane, and a channeled plate engaged over said tongues.
