INDEX.

Specification of Letters Patent. lgLtQ-'glljjegd` June 6,1922.

Application filed October 3, 1919. Serial No. 328,125.

To all whom t may concern:

Be it known that I, JAMES H. BAND, a citizen of the United States, and resident of vNorth Tonawanda, in the county of Niagara and State of New York, have invented new and useful Improvements in Indexes, of which the following is a specification.

This invention relates to indexes, and is a species of the genus more fully described and more broadly claimed in an application iiled concurrently herewith. a

In the accompanying drawings which 1llustrate the invention,

F ig.` l is a front elevation of a part of an index containing the invention, parts being broken away,

Fig. 2 is a vertical -section of the same;

Fig. 3 is an enlarged detail partly in horizontal cross section and partly in plan; y

Fig. 4 is a cross section on an enlarged scale of one of the index line 4 4 of Fig. l;

Fig. 5 is a cross section on an enlarged scale of one of the index slip holders on line 5-5 of Fig. l; and

Fig. 6 is a face view of a pair of the index slips.

The index frame may be of usual conv struction, and as herein lshown consists of a back A, preferably of sheet metal, having its opposite side margins bent to vform inwardly extending flanges a, a, providing channels for the ends ofthe sheaths or holders.

Each holder comprises a pair of relatively long and narrow, parallel, closedfaced sheaths, made of an integral piece of transparent, resilient, sheet material such as sheet Celluloid. The opposite longitudinal margins of the sheet are folded over and inwardly upon the middle section 1, to form a pair of sheaths or compartments 2 and 3 arranged side by side, each folded margin terminating in a lip 4 to close the Comparo ment. A

Either side of the holder thus formed may be used as the front face, but I prefer to use the fiat middle section 1 as the front face, as it affords a smoother and more nearly continuous surface when a number of holders are assembled in the frame, withfewer cracks for the accumulation of dust'.

slip holders on Furthermore each' associated pair vof index slips are more conspicuously grouped when marked by cracks only between pairs of slips than when a crack occurs between all adjacent slips as would be the case if surfaces 2 and 3 were' presented at the front.y

, The front face of one compartment of each pair is out out` as shown at 5, to'form an entrance opening through which the in-` dex slip may be inserted or removed,`with out removing the holder from the frame. 1 In the preferred form, inwhich the middle section l is the front vof the holder, this entrance opening 5 is cut through the middle section 1 opposite one of the folded margins 3.

The index slips 6 and 7 (Fig), of paper i or other suitable sheet material, are inserted` or removed endwise into orfrom their respective compartments, the slip 6 bearing the name or other relatively permanent mattery being placed in sheath 2, from which it cannot be removed without removing the holder from the frame, and the slip 7 bearing temporary or changing data being placed in sheath 3, in which it can be inserted or from which it can be removed through the' opening 5 without disturbing the holder.

I claim:

l. A holder `for index slips formed of an integral piece of transparent, resilient, sheet material, folded toy form a pair of relativelyv long and narrow parallel compartments ar.-

ranged side bysde in the same plane, adapted to hold separate index slips.

2. A holder for index slips formed of an integral piece of transparent, resilient, sheet material, having its opposite v margins folded over and inwardly upon the middle section to form a pair of relatively long and narrow parallel compartments arranged slide by side in the same plane, adapted to hold separate index slips.

3. A holder for index slips formed of an y integral piece of transparent, resilient, vsheet material, folded to form a -pair of relatively long and narrowparallel lcompartments arranged side by side in the same plane, adapt ed to hold separate index slips, the front face of one compartment being cutl awayy near the end to form anlentrance opening for an index slip.

4. A. holder for index slips formed of an integral piece of transparent, resilient, Sheet material, having` its opposite margins folded over and inwardly upon the middle section to form a. pair of relatively long and narroy'v parallel compartments arranged side by side in the same plane, adapted to hold separate index slips, a part of the middle seetion opposite one of said folded margins, near its end, being eut away to form an en 10 trance opening for an index slip.

Signed by me at North Tonawanda, N. Y., this 30th day of Sept., 1919.

JAMES I-L RAND.
