MARKER.

Application filed June 11,

To all whom it may concern:

Be it known that T, Gnovnu PERRY, a citizen of the United States of America, and esident of Chicago, Cook county, Illinois, have invented a certain new-and useful Improvement in Markers, of which the following is a specification.

Among the objects of my invention are the following: to provide an improved index mark, specially adapted for books or for indexing in general; to provide a mark simpler to handle and operate and cheaper to manufacture than any that has heretofore appeared in the prior art; to provide a mark which may be easily pressed home into position against the edge of the page without any particular or special attention on the part of the party who is putting the same in position; to provide in a. device of the above character a holder on the mark for the paper or other material upon which the inscription or identification sign is made, which will permit such paper or material being removed or put into position at will without in any way affecting the device; to provioe a mark of the above character which is made light and without a heavy metallic top. Markers that are made with such heavy tops are liable to fold the sheets or pages automatically as the book is opened and rendering the page liable to be creased if the book is accidentally closed. thereafter; and to provide other details of improvement tending to increase the efficiency and serviceability of a device of the above charactor. The means to accomplish the foregoing and other useful ends are hereinafter more fully set forth and claimed.

Referring to the drawings, Figure 1 shows one of the marks complete.

Figs. 2, 3, 4t and 5 show details of the mark shown in Fig. 1.

Figs. 6, 7 and 8 are modifications of the mark shown in Fig. 1.

Fig. 2 shows the element 2 of the mark folded at the line 3 to slip over the page (Fig. It may be of transparent mate rial such as celluloid. This element is, one continuous piece folded, as indicated in Fig. 1. The diagonally opposite corners a and 5 are cut so that the upper wing (Fig. 1) may be made to engage the page to be Specification of Letters Patent.

marked for the purpose of opening the two wings suificiently so that the mark may be clipped in place. It is obvious that it makes no difference which side is uppermost, because in one case the corner 6 which clears the corner at will serve and in the other case the corner '7 which clears the corner 5 will serve as well. The operator therefore 'need not bother himself with which way the thing is turned.

Fig. 3 shows the metal clip 8 bent sufficiently to permit the folded sheet 2 to be inserted between the prongs 9 and 10 as indicated in Fig. 1.

The holder 11 Fig. 5) of the same material as the sheet 2, or other suitable material, is cut so as to fit over the prongs of I the clip 8 where it may be cemented to the element 2 as indicated in Fig. 1. This holder is folded about the line 12 and so forms a loop into which the index piece 13 when folded about the line 14 may be inserted as shown in Fig. 1. The material may be any suitable for the purpose, paper, bristol board and the like. One of the modifications shown in Fig. 6 has two clips 8 and two index devices, each like the one shown in Fig. 1. The form shown in Fig. 7 has only one clasp but a broader index piece while the form shown in Fig. 8 shows two clasps and only one long index piece.

It will be understood that when the mark is to be applied to the page of the book, the page is stretched between the two hands and the marker is forced home into position with the forefinger until the edge of the page strikes the shoulder of the marker. This can be done with a minimum amount of care and attention.

l/Vhat I claim as my invention is:

1. In an index mark, the combination of a U shaped element for securing a mark in place, a U shaped index holder slipped over the first element for holding the index element, and a reinforcing hinge for the inner folded surface, said elements being of transparent material.

2. In an index, the combination of an index mark a U shaped element for securing said index mark in place, a U shaped index holder slipped over the first element for holding the index element, and a reinforcing spring for the inner folded surface located between the two elements, said index mark mounted upon said holder.

3. In an index, the combination of an index marl; a U shaped element forsecuring said mark in place, a U shaped index holder slipped over the first element for holding the index element, and a reinforcing spring for the inner folded surface located between the tWo elements and held 10 in posit-ion by the index element, said index mark mounted upon said holder.

Signed by me at Chicago, Cook county, Illinois.
