" vention relates to-temporary binders of the type disclosedin Letters Patent 1,132,231, dated "March 1 641915, a type inwlii'ch a plurality of flatbars are 'reir'i-ovably-held at their ends in b'racket's.

a In' binders or the Turner type (Patent No. 1",l'3-2,2 3-"l) merrier to place and remove the magazines the flexible strips or b'ars must be sprung orbovvd lat'ei'allyL This is often adiflicult operation; especially When the bars are riuineroiisand located close together; My 11 1- ventioneeeks to'iniprove the'bindr so as to avoid th'e objection above noted. V a v A further object'of -"-my-'iivention -is to con struct the brackets and bars so that'the' bars may. te races sna ed into place and re moved with little or no lateral bowing or bending thereof. 7

A further object is to provide a binder whose brackets have provisions to protect the ends of the binder back bar against injury.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects :I and ends, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description and then be particularly pointed ll out in the appended claims, reference being had to the accompanying drawing, in which:

Figure 1 is a plan view of an open binder equipped with my invention.

Figure 2 is an enlarged section taken longii tudinally through the binder back, the central '45 f brackets each parts being broken away.

Figure 3 is a perspective view of one of the brackets.

In the drawing in which like numbers of reference indicate like parts in all of the figures, 1 represents the covers of the binder and 2 the binder back which may be of the usual construction; Secured by rivets 5, or in any other suitable way, to the back 2 are end of which comprises .a base flange 3, having rivet holes 4, an upwardly inclined wall 6, an inner vertical wall 7, a top wall 8, an outer vertical wallj9 and a bottom flange 10, the flanges 3 and 10 and the wall 8 lying parallel to one another when in normal position. The brackets being made of resilient material can be flexed at the juncture of wall 6 and base '3'so as to be movable to the dotted ,{line position indicated at the right of Figure 'AppiicatibflMilMh 1934, Serial No. mass j jsclaim (oi.*129 g 2 for the purpose of admitting and releasing the flat bars 12. a l w The brackets are slotted at 11-, the s'lots' cit tending about half way along "the wall 8 mm wall 7 and down wall 7 a distance suificient for the depth of the bars 12 so' they may fit "in the sl'ots 11 and underlie the unsl'o'tted art of the-top wall 8 (see Figure '2). 1

The bars 12 have their ends 13 beveled so that by laying ther ods in the slots *(see dotted lines, Figure 2) and pressing the same down they will force the brackets to spreadapart sufficiently to enable thebar ends to pass into place in the brackets and hold the 3 magazine -15 in the binder. l

To release the magazine it isonly necessary to press downwardly dn" the bracket winch will cause it to assume the dotted line position at the right of Figure 2 and free the adjacent end of the bar 12 so it may be lifted out with the magazine in which it is located. Pressing down on the magazines at each side of the one to be removed will cause them to press down on wall 6 and thereby move the brackets to the dotted line position to release the bars 12 and enable the selected magazine to be removed. Then on releasing the pressure on the adjacent magazines the brackets will spring back to place and retain the remaining bars.

When the brackets are made to hold a large number of bars 12, the walls 6, 7, 8, 9 and 10 may be slit at intervals as at 14 so that the resilient action is in sections; i. e., only one group of bars need be manipulated to place or remove one.

The flange l0, underlying the back 2, and the wall 9, extending over the end thereof, protect the end of the back from injury. The flange 10 also serves as a stop to limit the spring action of the plate 6.

From the foregoing description, taken in connection with the accompanying drawing, it is thought that the construction, operation and advantages of my invention will be clear to those skilled in the art.
