i To all whom it may concern lJONES, a citizen of the proved loose-leaf binder of simple and duing-clips rable construction, possessing large expansion caplacity.

Numerous other important tained, as will be understood from the detailed description hereinafter given.

he invention is illustrated in 1ts p referred embodiment in the accompanying drawings, in which- Figure l represents view of a loose-leaf accordance with this section of the binder objects are ata broken perspective ledger constructed in invention; Fig. 2, a frame, taken as indicated atkline 2, Fig. l; Figf, a section taken as'indicated at line 3 ofgFig. 2 and showing one of the clamping-members employed; Fig. 3a, a section taken as ind1cated at line 3g of Fig. 3; Fig. 4, a section taken as indicated at line 4 of Fig. 2, showing in section the clamping-member depicted in Fig. 3; Fig. 5, an enlarged broken section, taken asvindicated at line 5 of Fig. 2; Fig. 6, an enlarged broken sectional view of the flexible back employed; Fig. 7, a broken sectional view, on an enlarged scale, of one of the fly-leaves or end-sheets employed; Fig. 8, a plan View, or development, of the flexible back employed; Fig. 9, a view showing both sides of a binding-clip used in connection with the flexible back; Fig. 10, a broken View showing a detail ofthe fly-leaf which is shown in section in Fig. 7; Fig. l1, a broken, sectional view, on an enlarged scale, taken as'indicated at line ll of Fig. 8, showing the manner in which the bindare secured to the edge-portion of the flexible back; Fig. 12, a view of one of the nutsor followers employed; Fig. 13,21 View of one of the guides for the flexible leaf-engaging connections which connect the two clamping-members; Fig. 14, a sectional viewshowing also one of the end-plugs forming a detail of the hollow clampingbar employed; and Fig. 15, a view showing v by screws 9.

in plan and in inner elevation "one of the links of the flexible connections employed.

In the embodiment shown, A, A. clamping-members, with which are pivotally connected cover-sections A3; B, B flexible connections between the clamping-members, sald flexible connections serving also as leafengaging members, or link-constituted binding-posts; C, a flexibleback for the binder; and D, D', fly-sheets of an imperishable natuewith-which the binder is desirably prov1 e The clamping-members A, A and the cover-sections A2 may be of any desired construction. It is desirable, however, that, where a high expansion binder is required, the clamping-members should both be hollow. ln the preferred form, which is shown, each clamping-member is hollow, and 1s formed by bending a strip of sheet metal into approximately hollow rectangular,

forni, in such manner as to bring the edges of the strip into spaced relation along the inner side of the hollow clamping-member, thus leaving a longitudinal slot .2 at the inner side of said clamping-member. ln the forming operation, the metal is curved or folded upon itself to form a longitudinal eye 3 at the inner or hinge-edge; and sections of the longitudinal eye are cut away, as indicated at the points 4, to afford spaces for projecting eye-portions 5, with which the hinge-members 6 of the cover-sections are equipped. rl`he eye-portions are connected by a pintle 7, and thus a piano-hinge effect etween ,the cover-section and clamping member is obtained.

An end-plug 8 is provided in each end of each hollow clamping-member, the end-plug having a shank 8a extend-ing into the hollow member and a against' the end-edge metal piece.

of the formed sheet- .lllach end-plug is provided lwith a bearing 8 for the reduced ends of the screw-rods employed. The plugs are secured in the ends of the tubular members ln each hollow clamping-member is journaled a right-and-left threaded screw-rod 10, whose reduced` extremities are received in the bearings 8, and thus the screw-rods are confined against longitudinal movement. At one end of the binder-frame, the plugs 8 are provided with perforations or sockets ,l1 adapted to receive a key, or the socketrepresent flange 8b which abuts l i 15, and at portion of a crank (not shown) which may be employed to rotate the screw-rod. The adjacent end of the screw-rod' is square to receive the key or small crank. A short distance from the end of each hollow clamping-member there is secured a guide-member or bridge-piece 12, which extends across the slot 2 anol is provided withya curved groove or guide surface 12a, about which the link-constituted flexible post, or flexible connection between the clamping-members, passes. The bridge-piece 0r guide 12 4may be secured in place by screws 13.

Fach right-and-left threaded screw-rod 10 is equipped with a pair of nuts, threaded sleeves, or followers 1l, each of which has a rearwardly-extending projection ll to which the adjacent extremity of the appropriate flexible connection is joined. The hollow clamping-members serve as guides within which the nuts can move, and prevent the nuts from rotating with the screwrods. ln Fig. 12,'1lb represents the threaded bore of the nut, IAand 1l represents the perforation in the projection 14,,- which receives the reduced shank with which the end-link ofthe chain is provided, as shown in Fig. 4.

The preferred arrangement is shown in Fig. 2, from which it appears that the flexible member i3 has its end-portions passed over two transverselyopposite bearings 12 and extending within the hollow clampingmembers A and A', the extremities being connected with nuts which are transversely opposite to each other and which are adapted to move in either direction, according .to the direction of rotation of the screw-rods; and it appears thatthe flexible member B is similarly arranged at the opposite end of the binder-frame and similarly connected with the other nuts with whichthe screwrods are equipped. f

It will be understood from the foregoing that either' screw-rod may be rotated independently of 4the other, to cause the flexible connections to be taken up or paid out, according to desire.

Flach flexible connection B, B is preferably composed of a single series of links 15 of circular cross section, the links being close-connected, so as to form a practically continuous surface so that the portions between the clamping-members will serve as leaf-engaging members or binding-posts. Thus, each link 15 (see Fig. 15) may be described as a very short rod-form member having at one end a web-form hinge-portion the other end projecting hingeears 15b. The web-form pivot-portion 15a is formedby milling or cutting away the piece, and leaving curved shoulders 15C, with which the curved surfaces of the ears 15b correspond. When the. links are connected, by pintles 15d, the links are free to posed of swing with relation to each other in one direction only, for it will be understood that they are held against lateral movement by the ears 15b embracing the webs 15a, and are held against swinging beyond the straight line, as shown in Fig. 2, by shoulders 15e. It will be noted that the shoulders 15e are staggered with relation to the shoulders 15C, this feature being of import ance to insure freedom of movement of the leaves, whose perforations engage the flexibleI posts. lt will be noted, also, 2 and 15, that in addition to having the ears 15b project beyond the shoulders 15, thus giving the overlap or offsetshouldei' effect mentioned, the shoulders 15C are inclined or at an angle to the axes links. Thus the shoulders 15e may be de scribed as undercut, and the effect is to prevent the possibility of the leaves entering between the joints by shifting longitudinally of the clamping members, while the staggering of the shoulders 15c with reference to the shoulders 15'3 prevents the leaves from entering the joints when moved along the chain-posts.

The flexible back C is preferably coman outer piece of leather 1G and an inner lining 17, which may be of thin leather; and a comparatively narrow strip of cardboard, or the like, 18, interposed between the members mentioned (see Fig. (l). The lateral edges of the flexible back (see Fig. S) are provided with slots 19, which extend in opposite directions from the central strip 18 and are of suflicient width to embrace the flexible posts in the manner shown lin Fig. 5. tions of the flexible back are disposed parallel with each other and lie adjacent the inner surfaces of the cover-sections A2, as shown in Fig. 5. The edge-portions are equipped with U-shaped binding-clips 20 (Figs. 8 and 11), through which the slots 19 are extended. The clips 2() are provided with recesses or eyelets 21; and detachable continuous clips 22 are provided. The clips 22 are U-shaped strips, provided in one member, or ply, with indentations 22, and in the other ply or member with indentations 22b (Fig. 9). rIhe indentations 22a engage alternate eyelets 21, and the indentations 22b engage the remaining alternate eyelets 21, it being understood that the clip 22 is of springy metal so that it can be applied, or detached, at will.

Each ly-sheet D, D preferably comprises a sheet of heavy, durable paper 23, which may be given any desired appearance, and a metal strip 24 connected to the rear edge o the sheet 23 by a linen strip 25 which is folded upon itself and serves to connect the parts in the manner shown in Figs. 7 and 10, thus aHording a hinge at 2G. The thin metal strip 24: and the folded'linen strip 25 are from Figs.

of the T he lateral por-I over one inch to ab unnecessary to use either intermediate telell1 scopic posts connecting the clamping-members, or intermediate flexible connections. It will be understood that whenone screwrod is being operated, the other screw-rod simply serves to hold the opposite ends of the flexible connections.

It is` desirable to employ two screw-rods, thereby rendering it possible to pay out the flexible connections to a greater extent. In this way, it is feasible, in a binder having a height of approximately ten inches, to secure a range of expansion from a little out six inches. Thus, a single binder of the improved construction may replace three` binders having a more limited range of expansion, between different points. It will thus be understood that the improved binder is of great advantage to the user, both from the stand-point of economy and from the stand-point of avoiding substitution of a binder of larger capacity, as increased ledger capacity is required.

From'th'e standpoint of the manufacturer, a vast uced cost of construction; second, because it is possible to reduce the stock to be carried to approximately,one-third; third, because it is easier to carry completed parts, and assemble them, according to necessity;

and fourth, because a large saving can be effected in the use of individual boxes for the ledgers, freight boxes for the individual boxes, and freightage, owing to the completely collapsed condition in which the binder can be shipped.

From the standpoint of the dealer, economy results, because it is possible to carry a smaller stock, and because less shelf-room is required for the ledgers, not to mention the increased salability from the fact that a greater range of expans1on is secured.

Since the embodiment of my invention in a commercially practicable loose-leaf ledger, I have learned, by investigation, that others have proposed the use of flexible connections attached to nuts actuated by screw-rods disposedin hollow clamping-members; but', so far as I am aware, no commercially successful device operating on this principle has been placed upon the market.

economy results: first, because of reing-posts passing about Among the features which render my invention highly practicable may be mentioned: lst, ing rods l() and the portions of the ilexible posts B as shown in Fig. 5; 2nd, the use of clamping-members (A, A) of cross-section elongated in planes perpendicular to the leafengaging portions of the flexible bindingposts, so as to occupy the same planes as the cover-sections, when closed; 3rd, the disposition of the actuating rods between the oused or inturned portions of the bindingpostsl and the cover-section hinges, thus attaining a maximum length and minimum thicknessof binder; 4th, the use of a flexible back having inturned marginal portions slotted to embrace the binding posts, thus giving finish to the binder and the rear ends of the leaves; 5th, improved flexible posts consisting series of links of such form as to afford a circular cross-section; 6th, the improved form of clamping-member employed, and thel resultant improved. hinge-connection; and 7th, the general mode of disposing and assembling the parts, which gives maximum capacity, minimum thickness, and a-parallel cover effect.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom, b'ut the appended claims should be constriled as broadly as permissible in view of the prior art.

arious embodiments may be given to the invention, the principle of which has been explainedin connection with the preferred embodiment.
