10 Claims.

The main objects of this invention are:

First, to provide a temporary binder or loose sheet holder of theclampingbar post type in which the sheet body may be opened for effective use and at the same time has a relatively small amount of binding margin.

Second, to provide a temporary binder or loose sheet holder having these advantages in which the sheet body is very securely held even in bind- :ers of large dimensions and a thick sheet body.

Third, to provide a temporary binder or loose sheet holder which is adapted for sheets originallyintended for the post type of binders.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embod illustrated in the a 'which:

Fig. 9 is a perspective view of one of the cover hinge members.

Fig. 10 is a perspective view of one of the amping bar hinge plates or members. In the embodiment of my invention illustrated, the covers I and 2 are of suitable structure and dimensions to accommodate the sheet body conventionally shown at 3. The clamping bars des .ignated by the numeral 4, in the preferred embodiment illustrated, comprise the outer nonmetallic relatively thick elements 5 and the inner metal plates 6, the elements being secured together by the screws 21.

The outer binder bar elements 5 have slotiment of the invention is ccompanying drawings, in

on on line 4-4 of Fig. 3. section on line 4-A 4-A The purpose of 1938, Serial No. 186,652 (01. 1291) like recesses 8 extending from their inner edges, the rear ends of the slots being adjacent the rear edges of the elements 5 as shown in Fig. 3.

The plates 6 have slots 7 opening to the recesses 8, these slots being arranged quite close 5 to the rear edges of the plate 6 or, in other words, quite close to the rear edges of the clamping bars.

this will appear as the description proceeds. The plates 6 extend across the recesses closing their inner sides and also rein- 10 forcing the elements 5 so that the completed clamping bar has the desired strength and rigidity.

The clamping bars are provided with hinge plates 9, those illustrated being of channel section andsecured to the plate 6 in an outwardly facing relation within the recesses by spot-welding at 29.

The covers are provided with arm-like hinge members l8 preferably of channel cross section disposed with the channels facing inwardly and with the flanges thereof pivoted to the flanges of the hinge plate by means of the pivots II. It will be noted that these pivots are located well to the rear of the center of the clamping bars but somewhat in advance of the slots lsee Fig. 3.

The hinge members ID are preferably inwardly offset at l2 so that they may be secured on the inner sides of the covers and the outer sides of their projecting portions are approximately flush with the outer sides of the covers and with the clamping bars when the parts are in closed position.

The flexible binding members l3 are secured at one end to the cover I as by means of the rivets Hi, their other ends being secured to the adjusting member l5 carried by the cover 2. As the details of the adjusting means form no part of this invention they are not further described herein. It will be noted by reference to Fig. 3 that these binding members are disposed longitudinally within the hinge members in to pass through the slots 7 in the faces of the clamping bars and that the reaches thereof extending between the clamping bars lie at the rear of the rear edges or end of the sheet body 3 as distinguished from being engaged within slots of the binding member receiving openings in the sheets. 50

The clamping bars are provided with sockets l5 positioned to receive the pins I1 on the post bars i8. These post bars are provided with nonaligned posts l9 engageable with holes 20 provided therefor in the sheets. In the embodiment illustrated, the pins H are located well toward the edges of the post bars, a part of them, the outer pins in the embodiment illustrated, being closely adjacent the front edges of the post bars and the center or intermediate pin being closely adjacent to the rear edges of the post bars.

The posts 59 are closely adjacent the front or inner edges of the post bars as best shown in Fig. 2, and it will also be noted that the post bars and the entire sheet body lie in front of the reaches of the binding members extending between the clamping bars. By this staggered relation of the pins or studs H on the post bars, the tendency of the post bars to rock on the clamping bars is minimized or, in other words, their engagement is stabilized against the various stresses to which they are subject in the manipulation of the binder.

The position of the binding members. relative to the post bars and to the clamping bars further results in holding the parts in position notwithstanding the relatively narrow binding margin of the sheets.

To urge the inner edges of the post bars inwardly upon the sheets, the webs of the hinge plates Q are provided with supports 2! for the binding members, see Fig. 3, these supports being in the form of outwardly disposed bead-like rolls on the front edges of the web portions of the hinge members 9, see Fig. 3.

This arrangement of parts insures a clamping stress of the binding members upon the inner edges of the clamping bars when the binder is closed and further stabilizes the clamping bars and post bars in their relation the one to the other.

In Fig. 8, I illustrate an embodiment in which the post bars are provided with telescoping post members 22 and 23.

My improved binder is adapted for receiving sheets designed for post binders of various types, it only being necessary to space the posts to correspond to the spacing of the holes 20 in the sheets. The sheets are effectively bound by a relatively narrow binding margin which of course is a desirable factor as a larger proportion of the sheets may be utilized for recording purposes or the sheets may be of less length for the same amount of writing surface as compared to the average post binder or binder of this general type now on the market.

I have illustrated and described my improvements in highly practical embodiments thereof.

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