LOOSE-LEAF BINDER.

Application filed August 7, 1922.

To all whom it may concern Be it known that I, FJMri. H. Flsorrnn, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented cer tain new and useful Improvements in Loose- Leaf Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to loose leaf binders and more particularly to means by which the posts are secured to the binder strip.

The general object of the invention is to provide an improved means of simple construction by means of which the post is firmly secured against displacement relative to the strip and at the same time provide a structure which may be easily and cheaply manufactured.

tipecifically, the invention includes means for preventing a rotary movement of the post with respect to the binder, as well as preventing longitudinal and angular displacement.

In the accompanying drawing:

Figure 1 represents a view partly in section and partly in elevation of one form in which my invention may be embodied.

Figure 2 is a bottom plan view of the structure shown in Figure 1.

Figure 3 is a view similar to Figure 1, but showing a modified form.

Figure 4 is a sectional plan view taken on the line of Figure 3.

Figure 5 is a view similar to Figure 1, but showing a further modification.

Figure 6 is a bottom plan view of the device shown in Figure 5.

Figure 7 is a view similar to Figure 1 showing a still further modification.

Figure 8 is a sectional view taken at right angles to the plane of Figure 7.

Figure 9 is a view similar to Figure 1, but showing a still further modification, and

Figure 10 is an end elevation of the device shown in Figure 9.

Referring more particularly to the drawing, the numeral 1 indicates a binder strip having a side flange and a back flange, the binder posts 2 being secured to and upstanding from the side flange.

In the forms shown in Figures 1 to 6, inclusive, the post is formed at its lower end with tongues 3, which extend laterally and Serial No. 580,254.

outwardly and are countersunk in the under side of the binder strip. The post is, also, provided with laterally extending tongues 41: which may be conveniently disposed transversely of the tongues 3 and extend above and engage the surface of the strip 1. It will be understood that the post maybe inserted and firmly secured to the strip at a single operation, the lower tongues 3 being countersunk will prevent the rotory movement of the post and in conjunction with the upper tongues 4 will securely prevent longitudinal or angular displacement.

In the form shown in Figures 3 and 4;, portions of thatpart of the strip which is punched out to receive the post are turned upwardly, as shown at 5, and form additional means for securing the post firmly' against angular displacement due to lateral rocking.

In the modification illustrated in Figures 5 and 6, tongues 6 are cut out of the strip 1 and folded underneath the countersunk tongues 3. Preferably, the tongues 4 are, also, used to prevent angular transverse displacement.

In the form shown in Figures 7 and 9, the tongues 7 are inserted through slots in the binder strip and are turned inwardly toward each other, being preferably countersunk in the central portion 8 of the strip. A flange 9 is, also, formed integral with the strip and is turned underneath the tongues 7 to secure the post against longitudinal displacement.

In Figures 9 and 10 the tongues 3 are used and the strip 1 is made with a side portion somewhat wider than in the other forms shown, which is folded longitudinally so as to provide a reinforcing flange 10, which, also, secures the post against longitudinal displacement.

It will be seen that all of the forms above described embody broadly the same principles and are embodied in the claims hereunto appended. It will, also, be understood that other modifications may be devised by means of which the principles of the invention may be carried out. It is, therefore, my intention to include all such modifications which fall within the scope of the claims.

I claim 1. In a loose leaf binder, a metallic binder strip having a post upstanding therefrom,

the lower end of the 30st havin lateral I I D n l PIOJGClllQIlS engaging the upper surtace oi the strlp and other lateral pro eotions en gagmg the under surface ot the strip, and

means for locking the post against rotary movement relative to the strip.

2. In aloose leatt binder, a metallic binder strip having a post upstanding therefrom, the lower end of the post having tongues Wisconsin.
