BINDER.

SPECIFICATION forming part of Letters Patent No. 724,709, dated April 7, 1903 Application/tiled June 26,1902, Renewed March 12. 1903. Serial No. 147.529. (No model) To (LIZ 107mm it 71u14/ concer/1,:

Be it known that I, HARVEY P. JONES, aeitii zen of the United States, residing at Chicago,

in the county of Cook and State of Il linois, have invented a new and useful Improvement in Binders, of which the following is a specification. My invention relates particularly to binders for loose-leaf ledgers, though the invention is adapted to other purposes.

Mypreliminary Objectis to provide a binder of this character of exceedingly simple and durable constructiomcapable of ready manipulation, and `more compact in form than binders yof this character have heretofore been made.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure 1 represents an inner view, partly in section, of a binder-frame, showing the same in its expanded position; Fig. 2, a section taken as indicated at line 2 of Fig. l; Fig. 3, a similar section taken as indicated Aat line 3 of Fig. 1; Fig. 4, a perspective View of a wedge-piece or expanding member einployed; Fig. 5, a broken inner face view of the back employed; Fig. 6, a detached view of a combined bridge-piece and sheave-block employed; Fig. 7, a longitudinal. section taken as indicated at line 7 of Fig. 1; Fig. 8, a broken section taken as indicated at line 8 of Fig. 5 and showing the manner of attaching the sheave-blocks; Fig. 9, a view of a staple employed for holding the screw-rod against longitudinal movement; Fig. 10, a

ibroken sectional View taken as indicated at line 10 of Fig. 7 and illustrating the manner y in which the screw-rod is connected with the bridge-piece by means of 'said staple; Fig. Il, a transverse vsection of the screw-rod, taken as indicated at line llof Fig. 12; Fig. 12, a fragmentary view of the screw-rod, and Fig. 13 a vieWof a modification of the binderframe.

The preferred construction is as follows: A represents-a back piece of substantially concavo-convex cross-section and equipped on its inner surfacenwith longitudinal ribs c a'; B B', clamping members or binding -post plates mounted to slide transversely on the Aback A and equipped with binding-posts lli;

C C', wedges or expanding members engaging oblique guides h, with which the clamping members are provided; I), a right and left threaded rod having screw connection with the members C C' and having a squared end cfor receivinga key 0'; E E, combined bridgepieces and sheave-blocks connected with the back A and equipped with rollers or pulleys E2', arranged in pairs, as shown, and F flexible members, preferably chains or cables, passing about the rollers E2 and connected with the members CC and with the binding-plates B ll'. The back A is provided at its end with transverse ribs orllanges il, upon which the binding plates ll ll' slide. Each bridgepiece is of the conligurationshown in Fig. 6 and is provided on its lower side with a lugf, which has a perforation through which the screw rod extends. The ribs c are straight throughout their length, as shown, while the ribs a. have their central portions lying'adjacentto the rod l) and their extremities offset with relation to their central portions, so as to pass on opposite sides of the lugs f. The central portions of the ribs a' are higher than the end portions, as illustraied in Figs. 3 and 7. '1`hc binding-plates are preferably of the form shown in crosssection in Figs. 2 and El, having portions g/ substantially' half-circularl in cross-section, upturned lianges g', inturned llanges y?, and rudimentary end flanges y.V 'lhe plates are equipped adjacent to the llanges y with perforated lugs g4, whereat the coter-sections.

(not shown) are to be pivotally connected. The guides I) have oblique in\'vardlyopen channels 7i., into which the ends of the wedges project. The wedges are of llat form, heilig provided on their under side with lugs lr, which have threaded connection with the rod D. 'lhe wedge-pieces have oblique surfaces t", which engage the oblique surfaces ofthe guides. At the end opposite the squared end e the rod l) is provided with a circumferential groove which receives a staple l', passing into channels Zi, with which the corresponding l'nidge-piece E is provided. This serves to hold the rod against longitudinal thrust. As shown in Fig. 1, the flexible members F are formed by bending a cable at 'its center and securing tlm same by means of a stud m to @c tzorresponding wedge- ICO fio

piece. The extremities of the cable are secured to studs m', provided within thebowed portions g of the binding-plates, said studs being located near the endsot the bindingplates. The rollers E are secured to the bridge-pieces b y means of screws, as shown. The outer surfaces of the bridge-pieces bear against the inner surfaces of the flanges g3, thereby actuating the binding-plates transversely on the back.

The operation will be readily understood from the foregoing detailed description. \Vhen the rod D is turned in one direction by means of the key c', the wedge-pieces C C are separated, thereby forcing the bindingplates apart, and when said rod is turned in the opposite direction said wedge-pieces are drawn toward each other, thereby drawing upon the cables and moving the bindingplates toward each other.

In the modification shown in Fig. 13 the back and binding-plates are ot' the construction already described and the rod D is mounted in the manner already described. In this construction the rollers are omitted from the bridge-pieces E, which latter are of slightlymodified form, being provided with inward extensions 1n. Ilere the binding-plates are provided with rollers m', over which pass cables m2, connected with the wedge-piece 0^ and with the extensionsmof the bridge-piece. The operation is similar to the operation of the binder shown in Fig. l, the wedge-pieces serving to separate the binding-plates aud the cables Serving to draw them together. 'lhe only diflereuce between the construction ofthe modification and the other construction is that the rollers are carried by the bindingplates instead ot by the bridge-pieces and the cables are secured to the bridge-pieces instead el to the binding-plates.

It readily will be understood that in both of the constructions described a binder of very compact form is provided, the space between the binding-posts and the back being exceedingly small. Moreover, the binder is actuated positively in both directions with no opportunity for loss of motion, and the requisite'expansion of the binding-plates is secured with comparatively small turning movement of` the rod I), the traverse of the wedge-pieces (l C being short.

Changes in minor details of construction within the spirit of my invention may be made. Hence no undue limitation should be understood from the foregoing detailed description, which has been given for elcarness of understanding only.

What I regard as new, and desire to secure by Letters Iateut, is

l. In a binder, the combination of two binding-plates, a back, a threaded rod mounted midway between said binding-plates, a nut connected with said rod, and cable connections whereby the nut in its movement serves to move said binding-plates, for the purpose set forth.

2. In a binder, the combination of two binding-plates, a member movable longitudinally of said binding-plates and having engagement kltherewith and serving to move the bindingplates in one direction, means for actuating said last-named member, and flexible connections joining said member with said bindingplates and serving to move said binding-plates in the opposite direction, for the purpose set forth.

3. In a binder, the combination of a back, two members movable longitudinally of said back, binding-plates movable transversely on said back and having oblique guides connected with said longitudinally-movable members, a screw-rod connected with said longitudinally-movable members and flexible connections between said longitudinally-movable members, said back and binding-plates, for 1 the purpose set forth.

4. In a binder, the combination of a back, two binding-plates equipped with oblique guides arranged in pairs, cross-heads engaging said guides and serving immediately to actuate the binding-plates in one direction, a right and left threaded rod serving to actuate said cross-heads, and flexible members connected with said cross-heads, said back and said binding-plates and serving to actuate said binding-plates in the opposite direction.

5. ln a binder, the combination of a back, two bi riding-plates having two pairs of guides, each pair of guides having its members convergent toward the adjacent end of the binder, cross-heads connecting said guides in pairs, a right'and left threaded rod for actuating said cross-heads, and flexible counectionsbetween said cross-heads, said back, and said bindingplates, for the purpose set forth.

G. In a binder, the combination of a back, transversely-movable binding-plates equipped with oblique guides, cross-heads engaging said guides, a right and left threaded rod for actuating said cross-heads,l rollers connected with said back, and flexible connections joined to said cross-heads and to said binding-plates, and passing aboutsad rQllers, for the purpose set forth.

7. In a binder, the combination of a back equipped on its inner surface with longitudinally-extending ribs having central portions increasing in height as the longitudinal center of the binder is approached and having end portions offset from the plane of the central portions, cross-heads equipped with perforate internally-threaded lugs working between said ribs, near the end portions thereof, a right and left threaded rod connecting said lugs, binding-plates, and connections between said bindingplates and said crossheads, for the purpose set forth.

S. ln a binder of the character described, having a back equipped on its inner surface near its ends with bridge-pieces, a threaded rod extending into one of said bridge-pieces and having a circumferential groove and a staple entering said last-named bridge-piece IOC and serving tooonfne said rod against longitudinal" movement, for the purpose set forth. -9. In a binder, the combination of a back equipped with rollers having axes at right- 5 angles to the back, binding-plates slidable transversely onsaid back, and means for 'ace tuating said binding-plates including flexible members passing abot said. rollers, and a threaded rod through the medium of which" said flexible members are moved, for the purxo pose set forth.
