Specification of Letters Patent.

Patented Aug'. 22, 1911.

Application filed December 20, 1910. Serial No. 598,411.

To all whom it may concern:

Be it known that I, Gsonon I). lVioGIN- rros, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Temporary Binders or Loose-Sheet IIolders, of which the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

My improvements are especially adapted to the type of binder shown in Letters Patent. No. 851,276, of April 23, 1907, to Harry F. Bushong, and as I have embodied them in practice in a binder of said type, I so illustrate the same herein.

The main objects of this invention are: First, to provide in a temporary adjustable binder, an improved back strip. Second, to provide in a temporary binder, an improved clamping bar hinge. Third, to provide in a temporary binder, an improved leaf hold ing or binding strip.

Further objects, and objects relating to structural details will deinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure l is a rear View of a structure embodying the features of my invention, the binder being shown open and the rear walls of the cover being broken away to better disclose the mechanism. Fig. 2 is a longitudinal section, the binder being shown closed. Fig. 3 is a detail perspective showing the structural details of the back strip. Fig. 4 is an inside perspective view of one of the clampin bars, the reinforcing strip 15 being omitted. Fig. 5 is a perspective view of one of the clamping bar hinge members. Fig. 6 is a rear view of such hinge member. Fig. 7 is a perspective view of a modified constructionV of the back strip. Fig. 8 Yis a cross section through one of the binding strips. Fig 9 is .an inside detail plan of one of the binding strips. Fig. 10 is a rear view of the binder closed.

In the drawing, similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, the covers l are preferably formed with chambers therein to receive. thc adjusting mechanism, and the back strip 2. These chambers are open at the inner ends of the covers. The covers are connected by the binding strips 3, which are connected to one of the covers, as by means of the rivets 4 and connected to the binder adjusting mechanism which is arranged in the other cover. This adjustingl mechanism, in the structure illustrated, con; sists of the screw shaft 5 mounted in suitable bearings in the covers and adapted to be manipulated, as by means of a key, and the bar G on the screw, the mechanism being that shown in the Bushong patent re ferred to. The binding cords 3 are connected to the cross bar 6. The back 2 is connected by means of the elastic straps 7 to one of the covers and by means of the straps 8 to the bar 6, so that the back strip is. adjusted by the binder adjusting mechanlsm.

The clamping bars 9 are pivotally mounted on the covers, the connections prefer ably consisting of the rigid hinge members 10 and the pintles 11 on the clamping bars, the pintles heilig arranged longitudinally in the bars, as shown in Fig. 4. The clamping bars are slotted to receive the ends of the hinge members 10 and are provided with pintle receiving members having pairs of ears 12 secured together at their rear edges and having laterally-projecting attaching straps 13, which are secured to the bars at each side of the slots. The ears en gage the sides of the slots and are supported thereby. serve to brace the clamping bars at this point, where they are weakened by slotting to receive the ends of the hinge a.ms. The pintle receiving members are preferably formed of sheet metal. The clamping bars are notched at 14 to receive the binding strips 3. The clamping bars are preferably formed of wood, and further reinforced b v the metal strips 15 arranged in grooves 1G formed in the inner sides of the bars. (Sec Fig. 2.) These reinforcing strips are not shown in Fig. 4.

The back strip is provided with a label opening, and preferably with a closure 17 These hinge members for said opening Which-forms a pocket for .the label 18. The closure piece 17 is secured opening. This supports the label so that it can be adjusted longitudinally of the opening to bring it into proper position on the back, as shown in Fig. 10, as the quantity of sheets or leaves in the binder is varied, Which varies the position of the back, and consequently the label if fixed thereto.l

In F ig. 7 I show a modified form of the label supporting members, the same being formed by-attaching strips of thin metal along the longitudinal edges of the opening. These thin metal strips can be stitched in the manner indicated.

I preferably form the binding strips, as shown in Figs. 8 and 9, by folding strips of leather longitudinally so that the edges abut and stitching longitudinally. This forms a strong flat binding strip having curved' smooth edgesl which is not likely to abrade or tear the sheets, as 21. The sheets have T-shaped notches 22 therein adapted to engage these binding strips. By thus forming the strips, they are of considerable size and serve to very effectively keep the sheets in alinement in the binder, and while the strips have suilicient iexibility they are, at the same time, of suiiicient rigidity to maintain their position in the opening of the binder.

While I have illustrated my improvements in an embodiment in which I have used them in practice, I am aware that they are capable of considerable variations in details, Without departing from my invention, but as such variations will no doubt be obvious to those skilled in the art to which this invention relates, I have not attempted to illustrate or describe the same'herein.

Having'thus described my invention,what I claim as new and desire to secure by Letters Patent is: y L

1. 'Ihe combination with the chambered covers, of binding strips suitably connected to one of the covers; an adjusting mechanism for said binding strips comprising a bar arranged in the other cover; a back strip having a longitudinal label opening therein arranged to telescope int-o said covers, one end of said back strip being connected to said bar of said adjusting mechanism and the other being suitably connected to the other cover; a closure strip for said label opening stitched on the inner side ofv said back strip, the stitching being spaced from the edges of the back strip opening to provide longitudinally-disposed label retaining members at each side of said opening; and a label arranged in said opening to slidably engage said retaining members.

2. The combination with the chambered covers, of binding strips suitably connected to one of the covers; an adjusting mechanism for said binding strips comprising a bar arranged in the other cover; a back strip having a longitudinal label opening therein arranged to telescope into said covers, one end of said back strip being connected to said bar and the other being suitably connected to the other cover; a label; and a pocket arranged to slidably support said label in said opening.
