Description

' loose leaf binders, and has objects the production of such a binder within which shects of paper can be easily- To all whom tt may concern: Beit known that I, Roman G. Himav, a-t

citizen of the United State residing att Cleveland in the county of uyeho a' and, State of hio have inventede eertsh new; and ii, fiil improvement, in Loose-Leaf'v Biiide of which 'the .followingfiis e full,

and quickly secured, from which they canbe readily removed and from which any one or more of theI shcets may be taken without tlie filing of c'li pings catalogues etc.

Loose leaf biiiders hvhich and attractive appearance an which are at i present in use contain devices more or less j complicated for securing the pa and this necessarily makes t em too ex- :i

causes4 each ers in place,

pensive to be included in the usnal ofiice c uipment, except to a limited extent. T ere are many places where their use would be a great convenience, but would involve uudue expense.

It is a further object of my invention. therefore, to produce a binder which will be neat in appearance as well as very strong and cheap, and these objects are accomplished in the binder illustrated in the accompanying drawings and set forth in the claims annexed hereto.

Figure 1 is a erspeetive view of my improved loose leaf binder; Fig. 2 is a transverse sectional view through the back of the binder adjacent one of the rings; Fig. 3 is a detail in perspective, which the rings are set into grooves in the outer back member; and Figs. 4 andl are i perspective views of the inner and outer members, respectively, of the back.

In the drawings in which like reference characters are employed to desi ate correspondirji parts throu hont t e several views, represents the ack, which is composcd general] of the inner member a and the outer mem erably madeof wood, and it is very essential that the grain of the wood in the member a' should run lengthwise of the piece, for a purpose hereinafter ex lained. At suitable distances throu hout its length, the member a' is provi cd with transverse groovcs a, which extend from the inner surface tliereof to a depth of about one-lialf its I grooves being I t closed position, it is desirable to have the thickncss, the bottoms of the preferably straightJ'as shown.

(present a neaty showing the way in r a'. These parts are prefdisturbing the arrangement of the remaining sheets. My binder is also applicahle to i of the grooves,

4 the fiber,

Foroed to a seat within each groove is a ring B. Each df these rings is made with a swiveled section b, which is joined lat b' to the body ortion of the ring. The op msite end o tie swiveled section is provi ed with a projection b', which en ages a notch or reeess in the end of the b y ortion of the ring with which this end of t e section is oda ted to ooperate. When all of the rings avebeen foroed into'their respective grooves, I glue, tack, or otherwiseI secure thc inner member a to the inside surface o the member a' between the longitudinal ribs aA The surfaces of these ribs adjaccnt the side edges of the members a' are curvcd to conform to the contour of the curred oxsed surface of the member (I.

I find it a savin of time in the asscmhling of the back mcin ers to employ hoth hrads ri' and glue for seem-ing the parts ri and u' together, as the brads hold the parts lirmly in place while the lne is drying, and therehy avoid the use o purpose.

lt will be seen by reference to Fig. 3 that, at the point where the rings engage the sides the depth of the groovcs is considcrably increased b the ribs (13. This roove to rmly emhrace over one-fourth the circumfercnce of each rin; 1 and, since the narrower than and the rings have to be actually forccd to a seat within the grooves, the rings will be held osit-ively against movement in any grooves are made slightly a vise or clamp for'that direction and the member (i, being made of a sufiicient width to cngage the interior of the rings, prevents the looscning of the rings and the Withdrawal of the same from the grooves. It will also be noted that, at the points where the member a engages the inteA rior of the rings, the member orms a chord for the inner circumference of the ring. which tends to prevent the creeping of the rin 1% is well known that the shrinka o of wood is in a cross-grain direction an that the shrinkage does not affect the length of and it is, therefore, essential, as previously mentioned, that the grain of the wood in the member a' should run parallel to the lon itudinal axis of the piece, or at substantia y right angles to the grooves ag,

for the purpose of preventin of the wood having an width of the grooves an to become loose. 4

The binder is provided with two covers C and D. These covers are Secured to the back member in a manner that will permit them to swing freely from a closed position, such as shown in Fig. 2, to an extreme open position, or until they are ermitted to cugage each otlicr at the ack. lVhen in the shrinking e ect upon theI caiising t ie rings covers convcrge toward the front and I, therefore, make the back of a width ater than the diameter of the rings pus the thickness of the two covers.

4To the outside surface of the covers I secure a covering of flexible material E, such se buckram, which extends from inside the forward edge bf one of the covers, back sei-oss the outside surface of one cover,

A second piece se shown at e'.

:of the i continuous corner or ct 'outer edge of eac (through which the rings pass) will be pravented from binding or clcnching against,-

i the rings.

As will appear b reference to Fig. l, the

cover li) projects inwardly and overhangs the back meiiihei These inwardly projcctii ortions e' ere adapted to en ,ag-e the rr ifions a' of the inner face of t e'niem f: which are located outside of the ribsl rf, such portions foriiiing jauibs for the inner edges covers. This irovides a rigid oi' lige between tlic cover und the back which is homogengous withl tiic 1 back.

'hilc I have described the. particular tform of split ring ns being that which i ircfer to employ in connection with inf: oose leaf biiu ers. I wish it unrlcrstood tha! I do not claim the ring as any feature of ing:

:invention and tliat I may use any type ni cover to the rear edge of the cover aiid is ci'cased at f and gliied to the rear edge c' of the cover. over the inside surface of the back member a to its other extreme edge (slots having been ciit for the accommodation of the rings B) where it is bent back u on itself or rrcased, as shown at f', gluet to the reiir edge of the cover and passes forwardly to ii poiiit corresnonding to the front edge oii the o posite cover. The material will. be pasted or glued to the inner member (i of the back. The ends of the back niay be covercd witli a piece of the covering material or may be painted to prodiice a finished effect and keep oiit moisture. This manner of covering the binder makes it very substantial and durable and, at the same time, nent in appearance.

I find, by making the inside surface of the back member a curved, that the rear or inner edges of the leaves act more satisfactorily when the .covers are opened and closed. If this surface were straight, it can be readily scen that, with the back down, when the covers are thrown back to a plane pnrallcl to the inside of the back, the leaves will divide and fall flat oii both covers. Upon closing the book, the leaves will have a tendency to slide to as near the center of the back member as the rings will permit, and the portions beyond the point where the covers are hinged will bend at an angle with res ect to the portions lying upon the inside o the back and will be'apt to be clenched on the rings and break or tenr iii the lioles by which they are niountcd upon the rings. shown, a'central ridge is formed throughout the back against which the rear edges of the leaves will abut and ywhich will tend to prevent the inward creepinV of the outside leaves, and the lioles within the leaves The material is then stretched l i I claim is:

' same, the rin being of such split ring which I believe will satisfactoriljvv accomplish the iii-pose.
