To a]! when if "my concern:

Be it known that 1, WILLIAM MAXWELL \Vnmnnou, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in LooseLeaf Binders, of which the following is a specification.

My invention relates to the construction of loose-leaf binders for loose-leaf lodgers, memorandum-'booksnnd the like and it consists in sundry im rovements herein to be described.

In the rawings hereto annexed, Fi re 1 is a perspective view of a loose-leaf inder and supporting-bar. Fig. 2 is a modification of the construction shown in Fig. 1. Fig. 3 shows in erspective a retaining-clip for the binder. Fig. 4 shows in cross-section the retaining-clip and binder assembled.

A preferred form of binde. is illustrated in Fig. 1, and this consists of a flat bar A, of sheet-metal, from which are-cut and bent upward the integral fin ers a, which are are ed over so as to nearly ut not qixite meet each other above the bar A. The gers a are in process of cutting the blank from which the inder is made out with beveled ends, so that when these ends are approached in the act of bending up the fingers a there remains between their 0 osed extremities a diagonal open slot at. he fingers aare made 0 enerous width, so that t e diagonal slot a s all occupy a considerable portion of the width of the top of the binder, measured transversely of the bar Al The sheets B are provided with slots 1), these slots being s aced apart to corres ond with the distance between the pairs of ri ers a measured lengthwise of the or or baclbplate A. In order to insert the sheet B, it is bent so as to be inserted between the fingers a a of both pairs until the slots 1; in the aper come opposite to the finers c',whent e sheet is allowed to straighten itself, andthus to intersect the slots or s aces a, in which gosition it cannot be with awn from the bin er unless it is torn.

Any desired number of sheets may be attached to the binder in the manner described, and any sheet, whether at the end or in the middle of a series, may be withdrawn or inserted at will.

Another form of binder is shown in 2, wherein the blank is cut to form aback-p ate A, asbefore, but only a sin lefinger a ,Where in the instance shown in Fig. 1 there was a pan. In Fig. 2 finger a. is cut of sufficient ength to extend when arched up across and down, so that its free end lies, preferably, a little below the lane of the top surface of thc back-plate A, w 'ch is cut away, as at A, to ggrnnt the dc ression of the free ends of the gels a. e sheet B is introduced into the binder in this case by being slip ed under the free ends of the fingers a so t at the slots b may embrace the fingers. Obviously the binder-plate made in this form will permit the insertion of loose leaves only at one s de of the mass of leaves or their removal in similar manner.

In Fi 3 I show the clip wherewith a b nder-p ate or back may be attached, if desired, and secured between rotective covers. The clip consists of a c annel of sheet metal,which may be sl' htly rounded at the central ortion ,the si cs 0 0 being curved over to orm the channel. Points C may, if desired, be struck out of the central portion to facilitate attachment of the channel-plate to a cover, as D.

B reference to Fig. 4 the manner in which the inder-plates are secured to the clip is made clear. The backplate A is cut in at the sides at a", so that when the fin are a. are bent upward the edge of the back-p ate A extends a little beyond the outer surface of the fingers a Thus, as shown in Fig. 4, when the plate A, which is made of such size as to lit the clip or channel C C, is slid into said clip endwise the edges of the bar or late A are engaged by the inturned edges C of the clip and are retained thereby, the fingers a projecting above the clip, so as to facilitate the tur and handling of the leaves B held by the bin er.

Either of the forms shown in Figs. 1 and 2 may be used with a retaining-clip such as shown in Fig. 3. J

The loose-leaf binder above described pro vides in a single integral structure a simple and effective binder from which all the structural and operative complications incident to articulated and reciprocally-movable parts are eliminated. The gist of the improvement, whether embodied in the form shown in Fig. 1 or embodied in the form shown in Fig. 2, consists in the plate having a rigid'arch secured thereto and refer-ably integral therewith, the said arch out so as to form a near] but not uite closed loop, the adjacent terminals of tie loop being so carried past each other or overlap ed that the terminals guard. each other, so t at a flat leaf cannot esca e from retention by the loo In other words, a leaf must be bent out ol its normal plane in order either to be inserted in or removed from the binder. Thus in Fig. 1 the terminals of the loop directly above the late A approach but do not touch each 0t er and are beveled, so that a fiat leaf can find neither entrance nor exit, the beveling of the terminals of the loo affording the simple retaining means. In i 2 also the loo or arch is bent downwar on the open si e, so that it terminates well below the plane of the u I per surface of the backlate, and in this orm' also the terminals 0 the nearly-closed loop reciprocally guard each other to prevent the esca e of a fiat leaf.

at I claim, and desire to secure by Letters Patent, is

1. A loose-leaf binder consisting of a plate havin a leaf-holding arch portion rigid therewith, bent so as near] a closed loop, the ad acent terminals of the loop reciprocally uarding each other to prevent the esca e ol a flat leaf therefrom.

2. A looseeaf binder, consisting of a plate having fingers rigid therewith, bent upward and inward so as nearly but not quite to meet above the plate, the adjacent terminals of the fingers reciprocally guardin each other to prevent the escape of a flat lea there- 3. A loose-leaf binder consisting of a plate having fingers rigid therewith, bent upward and inward so as nearly but not quite to meet above the late, the adjacent terminals of the fin ers being beveled, to form an open slot angu arly transverse to the center line of the plate.
