GUIDE-C if:

To all 'whom 'it may concern.'

lBe it known that I, FRANK M. VAwTER,

. a citizen of the United States, residing at facture and attractive in appearance,

Benton Harbor, Berrien. county, Michigan, have invented new and useful Improvements in Guide-Cards, of which the following is a specification. Y y

My invention, as will beunderstood from the description and explanation hereinafter givcn, is particularly adapted for application to the index or guide-cards of vertlcal ling systems now in extensive use for many urposes, mg used upon the indexes of books, particularly those of a heavy and substantial character, and in other cases where sheets or cards are plrovided with projecting tabs whereby the s eets are adapted to be turned or separated manually. :I have therefore illustrated and will describe my invention with reference to a set of guide cards such as are commonly used for vertical filing or in card indexes, but without intention of limitin my invention narrowlyv thereto.

vThe object of my invention is to provide a projecting manipulating tab which shall be simple, strong, durable, cheap to manu in general, shall yfu1fil,in a maximum de grec, all the requirements ofsuch tabs. To

this end I have devised the novel structure hereinafter described, and my invention consists in the construction, arrangement and character of the different parts of-such structure, the essential elements 4of which are recited in the appended claims. y

Of the drawing Figure 1 is a fragmentary face view of the tab and adjacent portion of a guide card, the tab'being shown somewhat larger in size than those in common use; t Fig. 2 is a sectional'view taken centrally of the sheet and looking in the same direct1on;

Fig. 3 is an enlarged section on the line 3-3 of Fig. 1; and Fig. 4 is a view of the top portions of a set of guide cards to which my invention is shown applied.

The same reference characters indicate the same parts in all the- -gures `of the drawing. p f

It has heretofore been proposed to reinforce tabs of guide cards such as those to which m invention relates with a facing of sheet ce uloid folded to extend over and Specification of Letters Patent.

cover the o posite faces ofthe tab, but in practlce it 1s found that while such a reinforcement is strong, sanitary and attractive card, the celluloid and wire being cemented.

to the card b any suitable cement. The wire length a ords a smooth, hard, rounded surface around which the celluloid facin curves and by which it is rigidly supporte in such manner that it cannot be crushed and sharply creased, either in the manufacture of the tab or subsequently, and is stifened so that in handlin the card the edge of the card is restraine against bending and iexing, with the result that the ce uloid will not crack along the edge as in the case of the prior form of construction mentioned.

It is obvious that while my Yinvention is particularly valuable as applied to a facing or reinforcement of sheet celluloid, it may alsov be used lto advantage with other sheet material, as paper, or cloth, if desired, and will give increased strength and durability to such structures. It isy further obvious that it may be applied to guide or index tabs wherever used, whether on the guide cards of vertical filing systems, or elsewhere.

I claim: K l

1. A guide card for vertical ling systems and the like and formed with a ro]ecting tab portion, said card having a fo ded sheet f celluloid facing cemented to the opposite faces of said tab portion and also having a length of round wire interposed between said facing and the edge of said tab portion along the foldin line of the facing.

2. A ide car for vertical filing stems `sand the like and formed with a pro]ecting tab portion, said card having a folded facing of sheet materialwemented to the oposite faces of said tab portion and also aving a length of wire interposed between said facing and the edge of said tab portion along the foldingrline of the facing.
