EGMONT B. ARNOLD, OF MILWAUKEE, WISCONSIN.

TEMPORARY BINDER.

Application filed July 26, 1915.

To all whom it may concern:

Be it known that I, EGMONT B. ARNOLD, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and. useful Improvements in Temporary Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to the subject of temporary binders, and more particularly to what is known as fold-engaging binders wherein the binder includes posts and bars or the like, the bars engaging the folds of the newspapers or books to retain the same within the binder.

The aim of the invention is to provide improvements in binders of the type generally stated above that will facilitate the removal or replacements of papers, books, &c., within the binder, such improvements residing in the supporting posts and the foldengaging bars by means of which the cost of production of the binder is reduced to the minimum, and the operation of removing or replacing the fold-engaging bars incidental to their use is simplified.

A simple and thoroughly practical form of the invention is shown in the accompanying drawing, wherein Figure 1 is a perspective view of a binder equipped with the improved supporting posts and fold-engaging bar. Fig. 2 is a detail view in section showing a preferred connection between the bar and the posts.

The improved binder in so far as its covers and back are concerned may be ofthe usual or any preferred form as this invention has special relation to the supporting posts and the fold-engaging bar. 7

The supporting posts are formed of resilient sheet metal, preferably flat, and have their bases 1 fastened to the inner surface of the back of the binder adjacent the ends thereof. The post portion 2 of the base projects outwardly from said base at right angles, the shape being obtained by bending the material. Adjacent its free outer end the post 2 is provided with a longitudinal slot 3. As is usual two of the posts are employed, and as such are formed of flexible material, the same may be readily flexed outwardly or inwardly without distorting their normally straight right-angular position relatively to their bases.

The fold-engaging bar A shown in the Specification of Letters Patent.

drawings may be of steel or other suitable metal or material and has its ends reduced and shaped to form hooks 5. The format on of the hooks at the ends of the bar, obvlously provides the rounded notches 6 beneath the end portions of said hooks. The bar 4 is of such a length that when its ends are engaged with the slots 3 of the posts 2, said hooks project slightly beyond the slots and the notches 6 interlock with the base edges of said slots.

In assembling the bar and posts, the resiliency of the posts permits said posts to be readily flexed outwardly for the reception of the hooks, after which the posts spring to their normal positions and thereby'firmly interlock with said bar. A reversal of the described operation permits the bar to be readily removed. V

It is to be understood from the foregoing that this invention includes the outstanding resilient posts provided with slots and the bar provided with the end hooks for engaging said slots, the engagement being obtained' by flexing the posts to permit the hooks to be engaged therewith, after which the natural resiliency of the posts causes them to spring inwardly and thereby automatically effect an interlocking engagement betweenthe base edges of their slots and the notches 6 of the hooks 5.

It is, also to be understood that while the invention has been shown as including but one bar and the posts therefor, more bars or more posts could be used when necessary or desirable.

I claim as my invention 1. A temporary binder comprising a pair of oppositely disposed posts formed of resilient material and having their free portions provided with alined openings, and a fold engaging bar having end hooks and notches adapted to be interlocked with the openings of the resilient posts.

2. A temporary binder comprising sup porting posts formed of resilient material and capable of being flexed to permit a foldengaging bar to be detachably connected thereto, said posts being provided with openings, and a fold-engaging bar provided with means for interlocking with the edges of said openings.

3. A temporary binder comprising posts formed of a flat strip of resilient material shaped to provide a binder back-engaging base and posts that project at right angles therefrom, said posts being capable of being have hereunto set my hand, at Milwanliee,

flexed outwardly from the base and being in the county of Milwaukee and State \of 1:

provided with means for engaging with the \Visconsin, in the presence of two witnesses.

ends of a fold-engaging bar, and a fold-en- EGlVIONT B ARNOLD gaging bar having its ends adapted for connection with thebar-engaging means of the Witnesses:
