ment as to admit of loose sheets or leaves being readily-bound in proper or desirable relation with ach other in such manner as to permit the ready removal of one or more of said sheets or leaves, or the insertion of additional or substitute sheets or leaves; to so construct my improved binder as to render the saline convenient tor use. heat in appearance and inexpensive in construction and to produce certainother improvements, the details of construction and operation of which will be more fully pointed out herein after. These objects I accomplish in the manner illustrated in the accompanying drawingin which: I

Figure l is a view in perspective of a book embodying my invention, with one of the cover boards thrown to the open position, Fig. 2 is a vertical section through a por tion of a modified form of the device, said section being taken through one of the binding bars, and, Fig. 3 isa detail view in perspective of the connected metallic members which form my improved binding means.

Similar numerals ret'er to similar parts throughout the several views.

1 represents the usual upper and lower cover boards of a book which are tlexiblv connected with the longer edges of a central curved back piece 2 which may be of the usual or any well known form, this curved back piece being omitted for the sake of clearnoss in illustration in Fig. 2 of the drawing. -l'n producing the binding members of my device, I employ two parallel mctal back plates 3, each of which is slightly curved in crosssection as shown, the ad joining edges of said plates being formed at intervals with tubular projections such as are indicated ath and 5, the projections of one of said members 3 being adapted, as shown, to enter the spaces between the cor- Application filed February 2 Specification of Letters Patent.

responding projections of the other niem ber, thereby forming a continuous hinge tube through which passes a hinge rod 6'.

As shown more clearly at T in Fig. 3'91: the drawing, the upper and lower or outer marginal portions ot the plates 3 are bent for 'ardly. said bent portions being doubled upon themselves and shaped in their outer portions to form barrels or tubes i These tubes T are notched or cut-a ayv at desirable intervals as indicated at T. the notches of one of the tubes 7* being opposite or in transverse alinementwith the notches of the remaining tube T. '8 and 9 represent respectively rods which are adapted to be removably inserted into the tubes T and 7.

Each of the plate members 3 has hingedthereto at the roar of its flange projection I, as shown at 79. a plate 10 which is adapted to have its outer portion suitably secured to or in the rear end portion of the cover board 1. By thus coni'iecting the wings or plate members 10 with the rear ends of the cover boards. it will be observed that the:

' curved back in the metallic binder, which is composed of the sections 3, will be retained in the position shown within the curved back member 2 of the book cover.

T he paper sheets or leaves 11 which are to be bound by the binding appliance herein shown, are formed at their inner ends with two or more openings 11 which openings when said sheets are laid one upon the other, are adapted to register one with the other. In binding these leaves, I employ two or more metallic binding bars 12 which are p'refe ably curved rearwardly, as shown, and

which are provided in their upper and lower portions with suitably separated openings 12*. These bars are adapted to be inserted through the registeringopenings1.1 of the sheets 11,, the ends of the bars fitting into the notches 7" of the tube 7* in the manner indicated more. clearly in Fig. 3 of the drawing. This being accomplished the binding bars 12- are removably secured in place by inserting the locking rods 8 and 9 through the tube members 7 and through corresponding holes 12 of the bars 12.

In the modified form of the device shown in Fig. 2, the parts are substantially like thos above described except, that; a plate 10 is used in place of the plate 10 shown in Figs. 1 and 3, the object. of constructing the plate asshown in this figure being to space the cover from the ends of the bars 12 to' was?! Assuming that it is desired to remove some of the sheets in the upper half of the' book, it will be'understood that bypulling the upperrod 8 outward from engagement with the upper'ends of the bars 12 and permitting the upper cover board and upper curved plate member 3' to drop downward to the position indicated in dotted lines in Fig. 2 of the drawing thejdesired number of leaves ma gagement Witlithebindingbars 12, or new leaves may be readily added to those already bound together. It is also'evident that by removing both the rods 8 and 9, all the bound leaves may be-readilyv disengaged from the bars 12-, or if desired-the bound body of leaves together with the binding bars may be removed from engagement with the binder back. By providing more than-one opening 12 in the member-12,-- it will be seen that the thickness of -the device as a whole may be reduced when only a few leaves are carried upon said members When said leaves are so few in number that they do not cover the inner openings '12, the hinge rods 8 and 9 are inserted through these inner openings, the hinged connection or" the members 3 permitting this to be done.

From the construction and operation described, it will be seenthat comparatively simple and inexpensive means are rovided for readily and conveniently binding loose leaves into book form and for disconnecting or removing said leaves from the What I claim, is: Y

bination with a cover comprising upper and lower cover boards and a back having a flexible connection with said boards, of a binden back comprising parallel sections 3 hinged one to the other at the center of said binder back, plate members 10 hinged to said members 3 and having rigid connections with said cover boards, binding bars adapted to be inserted through openings in the leaves to be bound, said binding bars being detachably connected With the upper and lower portions of said sections 3.

2. In a binder for loose leaves, the"combination with a cover comprising upper and lower 'cover boards and a back having a flexible connection with said back boards, of a binder back comprising parallel sections 3 having a hinge connection one with the other, each of said sections having an inwardly projecting portion terminating in a tube, said tube being notched at intervals, upper and lower plate members hinged to said members 3 and having a; rigid conned tion with said cover boards, binding bars having openings therein, said binding bars adapted to be inserted through registering openings in the leaves tobe bound and having their ends adapted to enter the notches of the tube terminations of the plate pro- 'jections 3, and locking rods adapted to be passed through said tubes and through the openings in said binding bars.

In testimony whereof I aflix my signature in presence or two witnesses. CHARLES M. oo'rr.
