ADJUSTABLE INDEX.

Application filed March 4, 1919. Serial No. 280,637.

To all. whom it may concern: I am enabled to use for the manufacture of Be it known that I, JOHN T. QUIGLEY, a the index strips a sheet of paper of moderate citizen of the United States, and a resident thickness suitable for use in a typewriter. of Boston, county of Suffolk, and State of After the data has been written on the sheet. 5 Massachusetts, have invented an Improvethe latter is severed to form the individual ment in an Adjustable Index, of which the strips which are then suitably folded to give following description, in connection with the them the requisite thickness and stability.

accompanying drawings, is a specification, Preferably. th strip is folded in such a like characters on the drawings representingway as to form atube having a generally 1% lik a ts, quadrilateral cross-section, as shown in Fig.

This inventionv relates to indexes and aims 4. To facilitate the. use of a typewriter in to improve index equipments of the class placing the names or other data on the in which the index elements are in the form strips, I )refer to use a suitably prepared of narrow strips arranged in parallel rela-- sheet 11, s iown in Fig. 5, which is provided 15 tionship in a panel-like mounting, in which with appropriate folding and severing they are adjustably and 'removably held. lines arranged in successive groups. In the My invention will be best understood by present embodiment, the sheet is provided reference to the following description, when with weakened portions forming lines taken in connection with the accompanying 12-12, and other weakened port-ions form- Ztl drawings of one specific index equipmenting lines 13l8, parallel with one another selected for exemplification, while its scope and spaced at suitable distances apart. will be more particularly pointed out in the Preferably, the weakening of the sheet is appe ded laim done by perforating the same, the perfora- Tn the drawings: tions in this case being very narrow and 2557 Fig. I is an elevation of an index equipspaced rather far apart in order to facilitate ment embodying my invention; the folding of the sheet without danger of its $0 Fig. 2 is a sectional view on an enlarged being severed along these lines.

Fig. l is a perspective view of one of the To facilitate severing the sheet, T prefer index elements; to rovide additional weakened lines ll, Pg. 5 is an elevation of a prepared sheet pre erably formed by rows of perforations from which the index elements are made; which are herein relatively shorter, wider and closer together than those of the fold- Fig. 6 is a sectional view on. an enlarged ing lines.

o fication an index comprising a plurality of The previously prepared sheet is torn apart index strips 10 arranged in series, edge to on the severing lines, and the strips thus edge, in parallel relationship. These strips formed are finally folded into the tube-like g are intended to receive a name or other iden shape shown in Fig. 4:, whereupon they are tification, which in practice is usually apin readiness to be placed in asuitable mountplied directly to the strip by means of a ing, such as that now to be described. "loo typewriter. Preferably, the mounting and the arrangellnstead of mounting the index strips in ment of the index strips therein is such that celluloid or other holders common to the the latter may be removed and replaced by 50 prior art. I prefer to prepare the strips in simply sliding them lengthwise in their norsuch manner that the holders may be dismal plane into and out of the mounting.

pensed with entirely, yet without danger of Preferably, also, the mounting is doublethe strips becoming displaced by their edges faced,that is to say, provision is made to slipping past one another. By this means, receive two sets of oppositely-facing index elements. since this arrangement tends to conserve space. Referring now to Fig. 3. the preferred mounting comprises a thin metallic plate 15. having opposite marginal portions bent to form inturned flanges it on both sides of the plate 15, thereby providing two channels 1?. ()ne of these channels receives one set of ends of one series of the in dex strips 10. while the other receives one set of ends of the other series of index strips. as cl arly shown in Fig. 3. The other ends of the two sets of strips are held in place by suitable means. such as retaining bars, here.- in elongated metallic strips is extending across the index elements and suitably se cured to the plate In the present example, the upper and lower ends of the plate (see Fig. l) are wrapped about upper and lower wires l9 and 2t), herein provided with pintles 21 and 22. by means of which the mounting may be hinged to a suitable support (not shown). The retaining strips 18 are preferably likewise wrapped about the upper and lower wires 19 and 20, and suitably secured. thereto. as by electric spotwelding process. As a means to reinforce the intermediate portions of the retaining strips 18. and to prevent them from spreading out of parallelism with the plate 15, I have herein provided a plurality of generally til-shaped clips 23, best shown in Fig. 3,

said clips being provided with arms 2-1 and 27 suitably secured to the flanges 16 and retaining strips 18, as by spot-welding thereto. Une or more of theseclips will be used for each retaining strip, according to the length and degree of stiffness of the latter.

()wing to the cellular character of the index elements and the fact that they are made of paper. the latter have a certain degree of elasticity. and this characteristic is made use of in holding them in place. To this end, the thickness of the index elements when folded as in Fig. at should be such that it must be slightly compressed to permitit to be introduced between the plate and retaming strip 19. The overlapping edges of the index element tend to spread apart as in Fig. l before the element is introduced into the mounting. but subsequently the confined position which it occupies tends to compress the element and force the flaps inward. as well illustrated in Fig. :2. The natural elasticity of the paper then prevents the index elements from being accidentally Withdrawn. 'tfhen it is intended to remove one or more oi" the index elements. this may be done by exerting an inward pressure on the front face by means of the finger, or a rubber eraser. or a suitable sharp instrument, which is: then moved toward the right (Fig. 3),thus slidin the index element lengthwise out of its place, as indicated in dotted righthand side of Fig. 3. the index elements may be It is evident that rearranged from lines at the time to time. at pleasure, new names added, and old ones removed.

Having thus described one embodiment of my invention. but without limiting my self thereto, what I claim and desire by Letters Patent to secure is: 1

1. In an adjustable index, the combination of front and back guides, and a series of index bars received between said guides and abutting edge to edge, each of said bars comprising a sheet of paper folded to present longitudinal folds. and being thereby rendered resiliently expansible in thickness be tween said guides. whereby it is retained in place by frictional engagement therewith.

In an adjustable index. the combination of front and back guides, and a series of index bars received between said guides and abutting edge to edge, each of said bars comprising a sheet of paper folded to present longitudinal folds at its said edges, and a pair of flaps extending from said folds in opposite directions and having a tendency to unfold, said bar being thereby rendered resiliently expansible in thickness between said guides, whereby it is retained in place by frictional engagement therewith.

3. In an adjustable index, the combination of front and back guides, and a series of index bars received between said guides and abuttingedge to edge, each of said bars comirising a sheet of paper folded to present a writing tablet at the front, a pair of longitudinal folds at its said edges, and a pair of flaps extending inwardly from said folds at the rear, said bar being resiliently expansible in thickness between said guides and being held under compression therebet-ween.

. 4. The art of making folded index strips, which is characterized by preparing a sheet with weakened parallel lines, writing or printing the index data between said lines, then severing said sheet along said lines to form strips, and finally folding said strips along lines parallel with their edges.

5. The art of making folded index strips, which is characterized by preparing a sheet with weakened parallel lines some of which are weaker than others, writing or printing the index data between certain of the less weakened lines, then severing said sheet along the more weakened lines, and-finally folding said strips along said less weakened lines.

6. An index making sheet having a plurality of parallel folding and severing lines arranged in successive groups, each group comprising four folding lines, and the area containing each group being separated from the next adjacent group area by a severing line.

7. An index making sheet having a plurality of parallel, weakened lines arranged in successive groups, each group comprising four weakened lines, and the area containing each group being separated from the next adjacent group area by a line weaker than the four lines of such group.

S. An index making sheet having a plurality of parallel, weakened lines arranged in successive groups, each group comprising two weakened lines, and the area containing each group being separated from the next adjacent group area by a line Weaker than the two lines of such group.

9. An index making sheet having a plurality of parallel, weakened lines arranged in successive groups, each group comprising two lines formed by perforations spaced relatively far apart, and the area containing JOHN T. QUIGLEY.
