' 6 BINDER Filed Sept 9, 1936 CLARENCE 0. musssu NNNNNN O R A I RNEY mama July as, test PATENT- res me nmoaa Clarence D. signor to 'li'russell, Poughkeepsle, N. Y., Trnssell Manufacturing Company,
Poughkeepsie, N. Y., a corporation of New York Application September 9, 1936, Serial No. 99,904 9 Claims. 129-1) This invention relates to ring binders. Special objects of the invention are to provide a binder of simple, inexpensive construction and particularly well adapted to be made up of celluparts hereinafter defined and covered in the claims. 5 The drawing accompanying and forming part of this specification illustrates a practical and at present preferred embodiment of the invention, but itis to be understood that the structure may be modifled'as' regards this particular disclosure, all within the true intent and scope of the invention.
.Flgurel is an end view of a form of the binder .-.with leaves or sheets confined therein.
Figure 2 is a broken face 5 and boiind sheets. t
Figure 3 is an enlarged broken perspective view of the binder structure.
As shown in the several views, thelbinder consists of a back member I and ring elements 13, 9, extending from the opposite longitudinal edges of the same toward eachother and constituting two sets of rings for holding the two groups of sheets l0, ii attached to the opposite edges of the back member.
In the present illustration the back member is aconcavo-convex member with the convex side a curved on a relatively fiat arc on the order of the curvature of a well-bound book and the ring elements are curled inwardly toward each other over 49 the concave face of the back member.
Also in the present disclosure the ring elements at the opposite edges of the back member are directly opposite and have their end portions 80,,
5 9a contacting and extending into abutting enjgagement with theinner concave face of the back member. In this way'the opposite sets of ring .elements brace each other and in turn are reinforced by and brace the back member. If considered desirable, the face to face meeting portions of the rings may be cemented or otherwise secured together or the ends may be secured to the back member or both such fastenings may be used. Ordinarily, however, such is unneces- 55 sary where, as preferred, the back member and desirable objects are by the novel features 1 same, the rings 'may be engaged with orview of the binder sheets of different character or ring elements are made of resilient spring material.
When constructed of celluloid, celluiosic or similar material, the back member may be "struck out or otherwise formed as a flat blank with the ring tongues or fingers projecting straight from the opposite longitudinal edges of the same, after which, under proper heat, the back may be convexly curved and the fingers curled inwardly toward each other over the concave face of the member. with the parts set in such relation the whole constitutes a spring structure which'will yield as necessary and in which the rings can be sprung and held open by a machine or tool in the nature of a spreading mandrel, until the appropriately perforated sheets are strung over the then closing to hold such sheets as the spreading device releases the rings. 'If desired, the sheets may be slotted so that they disengaged from the rings without spreading the same.
The present structure, it will be evident, is par ticuiarly advantageous where it may be desired to bind up in one volume, two separate sets of relating to different subject matter. These two groups of sheets may then be laid out fiat and the sheets of either group turned back and forth over the other. 1, The structure also has the advantage that the two sets of rings project inward from the back memher. a lesser distance than a single circular set of rings capable of holding an equal thickness of sheets. i E
The use of two sets of rings in place of only one set also enables the back to be made relatively flat, instead of taking the curvature necessary to accord with a single set of circular rings. The
structure also is such that it may be readily manufactured in continuous lengths and then cut into the lesser lengths desired for different size books. The back member can vary considerably in width and when it is desired to make it extremely narrow it would then serve principally as a connecting member rather than a back.
I claim: I
l. A ring binder comprising a concave-convex back member having ring elements extending from the opposite longitudinal edges of the same inwardly toward each other over the concave side of the same, said ring elements at the opposite edges or the back member being disposed opposite each other and having abutting terminal portions extending toward the concave face of the back member. K
2. A ring binder comprisinga concave-convex from the opposite longitudinal edges of the same inwardly toward each other over the concave side of the same and having the free ends of the same,
extending into engagement-with the concave face of the back member,
4. A ring binder comprising a concavo-convex back member having oppositely disposed ring elements extending from the opposite longitudinal edges of thesame and curled inwardly into engagement with each other and into engagement with the concave face of the back.
5. A ring binder comprising a back member having ring elements extending from the opposite longitudinal edges of the same and curved inwardly over the inner face of said back member to constitute separate sets of rings attached to the opposite edges of said back member and said two sets of rings meeting at the intermediate portion of said back member.
6. A ring binder, comprising a concavo-convex back member having a row of integral binder ring elements along one edge andextending inwardly from that edge over and toward the intermediate portion of the concave face of said back member and forming one complete integrally attached binder extending along one edge and within the hollow of the back member and a second row of binder ring elements integrally attached to the opposite edge or said back member and extending inwardly from said second edge over and toward the intermediate portion of the concave face of the back member and thus forming a second complete binder within the hollow of the .back member and opposite the first binder exgitudinal edges of the same with those extensions at one side similarly curved in complete binder rings forming a complete binder along one edge of the back member and those extensions at the opposiite edge curved alike in complete binder rings forming a second complete independent binder along the opposite edge of the back member and in side-by-side relation to said first complete binder.
8. A duplex double ring binder, comprising two complete sets of binder rings, said sets disposed in side-by-side relation and secured in such relation by a connecting intermediate member forming a single back for said two side-by-side ring binders, said connecting member and the two sets of binder rings being of integral construction with the binder rings formed as integral extensions of said connecting back member.
9. A double ring binder, comprising a'back member of sheet material and two sets of integral ring extensions ofv said back member, said ring h extensions projecting from said back member and curled upon themselves in the form of two complete ring binders in side-by-side relation and extending longitudinally of said back member.
