BINDER.

Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed January 29, 1915. Serial No. 4,992.

To all whom it may concern:

Be it known that I, WVILLIAM GIrFoRD J ONES, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Binders, of which the following is a specification.

This invention relates particularly to loose-leaf binders; and the primary object is to provide a binder which can be used as a transfer binder, or for-analogous purposes, the binder being of improved construction and provided with locking means operating in an improved manner.

he invention is illustrated in its preferred embodiment in the accompanying drawings in which- Figure 1 repreesnts a broken plan View of a transfer binder embodying the invention; Fig. 2, a broken inner plan View of the lower cover-section and clamping-member connected therewith; Fig. 3, a broken inner plan viewofthe upper cover-section and clamping-member connected therewith, the clamping-member, being equipped with an improved locking means; Fig. 4, an enlarged broken sectional view, taken as indicated at line 4, Fig. 1'; Fig. 5, a broken sectional view of the upper clamping-member, taken as indicated at line 5 of Fig. 1; Fig. 6, a broken sectional view, taken as indicated at line 6 of Fig. 5; Fig. 7, a sectional View of the upper clamping-member, taken as indicated at line 7 of Fig. 1; and Fig. 8, a perspective View of one of the locking devices employed.

In the preferred construction, Which is illustrated, A represents a lower cover-section equipped with a clamping member A from which rise sectional binding posts A and B, an upper cover-section attached to an upper clamping-member B, which is fitted with looking devices B The cover-sections are preferably pro: vided at their rear ends with hinge-eyes 1, for connection, by means of pintles 2, with hinge-eyes with which the clamping-members are provided at their inner edges.

The lower clamping-member A may be posts extending through clamping-member,

of any desired construction, suited to firmly support the posts A s shown, it comprises a sheet-metal member 3 bent into hollow form, the edges being left separated at the inner side of the hollow member to afford a longitudinal slot 4. In the forming operation, hinge-eyes 5 are provided at the inner edge of the hollow member, by bending the metal at that portion into tubular form and cutting away portions at 5 to accommodate the hinge-eyes l. The tubular members are fitted with end-caps, or endplugs 6, which are recessed to accommodate the sheet-metal wrapped about the plugs, so that flush surfaces Will be provided. The end-plugs are secured in place by screws 7. A short distance from each end of the clamping-member A,-there are provided inner-plugs 8, which are secured in place by screws 9. The sectional posts A rise from the inner-plugs 8, the lower ends of the the slot 4, and being firmly secured to the plugs 8. The upper clamping-member B, which is made hollow to contain the locking devices, likewise preferably comprises a strip of sheetmetal 3 which is formed in the same manner as in the case of. the lower clamping-member, thus side of the upper clamping-member a longitudinal slot 4, and at the inner edge of the upper clamping-member the hinge-eyes 5. End-plugs 6 are provided for the upper which are secured in place by screws 7, as in the case of the lower clamping-member.

Each locking device B prises a plug 10 provided post-receiving bore 11 and an intercepting inclined ball-bore 12; a small lever 13located in a longitudinal slot 13 with vwhich preferably comwith a vertical the plug is provided, and supported on a. transverse pivot 13"; a friction-lock ball 14 located .in the inclined bore 12 and embraced above and below by the bifurcatedext'remity of the lever 13; a small coiled spring 15 seated in a suitable socket or bore 15*, which is crossed by the longitudinal slot 13 of the plug, the upper edge of the lever 13 being providing at the inner or lower recessed to receive the lower end of the spring 15; and a push-button 16 having its, lower end connected, by a pivot 16, to the offset inner end of the lever 13.

As will be understood from Figs. 4 and 5, the ball-bore 12 inclines downwardly and toward the post-bore 11, and it intercepts the bore 11 along one side, thus providing a tapered slot 12, through which the ball 14 may project slightly into the post-bore.

The upper wall of the hollow clampingmember B is provided with a perforation 17 for the push-button 16. In the assembling operation, the plug 10 and the co-acting parts of the locking device mounted thereon are inserted into the hollow clamping-member before the end-plug is inserted, the push-button 16 being deflected upwardly through the opening. 17 as the plug 10 is shoved inwardly to position. The plug 10 is then secured in position, by screws 18 It will be understood that the spring 15 is entered in its socket and placed under compression as the plug 10 is shoved into the tubular member, the upper end of said spring bearing against the'upper wall of said tubular member.. Finally, the end-plug is inserted and secured in position.

From the description given, it will be understood that when the upper clampingmember B is being shoved down to clamp the leaves of the book, the balls 14 willnot interfere with such action; but any upward pressure upon the upper clampingmember causes the balls to bind between the binding-posts and the downwardly converging opposed-walls of the ball-bores. The springs 15 tend to force the balls downwardly and into locking engagement with the posts, this action occurring because the forked extremities of the levers 13 engage the balls above and below. When desired, the push-buttons 16 may be depressed, thereby lifting or releasing the balls, thus enabling the upper clamping-member to be lifted freely on the posts. It thus appears that the frictionally-acting balls are spring-- actuated in one direction, and may be manually lifted at will.

The improved construction is simple, easily assembled, durable, and affords an effective locking device possessing great certainty of action. These features will be readily appreciated by those skilled in the art.

No unnecessary limitation should be understood from the foregoing detailed description which has been given for clearness of understanding only; but the appended claims should be construed as broadly as is permissible in view of the prior art.

iWhat I claim as new and desire to secure by Letters Patent is:

In a binder, the combination with a hollow. form,

being left separated at the inner side of thelower clamping-member equipped with a binding-post rising therefrom, and an upper clamping-member having a post-receiving perforation, of a plug within said upper clamping-member provided with a post-bore and anintersecting inclined ball-bore, a lever pivotally mounted within said plug and adapted to-elevate said ball, and a pushbutton pivotally connected with said lever and projecting through the upper wall of the upper clamping-member and serving to actuate said lever.
