MARKER.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed August 1, 1919. Serial No. 314,656.

To all whom it may concern:

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

My invention relates in general to an index mark of the character used to index or mark the pages of a book or for indexing in general.

Among the objects of my invention are to provide an improved mark of this character which is much more simple and efficient than any that has heretofore been used, one which is cheaper and more simple to manufacture, one which has fewer parts than others, one which is very easily attached to the leaves of a book and which while remaining fixed in position while in use, may be easily detached from the book, and one which is very light and takes up little space so as not to cause binding or folding of this paper when applied thereto, and one that can be flexed without tearing the leaf to which it is attached. Also the index or character is applied in such a manner as to be easily changed if desired. I

have provided certain other details of improvement tending to increase the serviceability of such a device, the means for accomplishing which are more fully set forth and claimed hereinafter.

Referring to the drawing, Figure 1 is a top view of the marker attached to a book leaf.

Fig. 2 is an enlarged side view of the same.

Fig. 3 is similar to Fig. 1 showing the marker flexed to one side.

Referring to the drawing more in detail the marker is made of a strip of transparent material which is folded in the manner indicated in Fig. 2. This strip 3 may be of any suitable flexible material such as celluloid, mica or the like; preferably it may be of transparent material but need not be so. The marker is fastened to the page 2 by slipping the marker into position. The clip 4 which may be made of any material such as brass, steel or any other material having sufficient strength to hold the marker in place. It will be understood that when the marker is slipped into place the prongs of the clip 4 are sprung by the page 2, thereby causing the marker to be pinched into position. It will be seen that the marker is foldednpon itself so that the outer fold 3 is not 1n contact with the page. As I have shown it the index A is applied to a piece of material secured to the inside of the loop of the marker that projects beyond the page. Although I have shown this index on the inside it can be just as wellon the outside and may as a matter of fact be imprinted or put upon the outer surface of the marker itself. It often happens with markers that are on the market that they are secured infiexibly to the page and consequently if the outer end to which the index is applied is struck accidentally by the hand or by anything else the page is crumpled or torn. With this design of marker that I show in the drawing if the projecting end of the marker is struck it merely flexes to one side as shown in Fig. 3 and instantly reinjects itself into position as shown in 1 without tearing the page. By referring to Fig. 2 it will be seen that the two ends of the loop or strip of which the marker is made are brought together and suitably secured. This may be done for example, by means of any suitable cement or in any other manner. The bending of the transparent strip and the folding back of the same as before described, forms an in terior approximately U-shaped body and exterior substantially parallel side members, one of which is provided with a substantially L-shaped terminal portion or extension forming an outer U-shaped portion and overlapping the other side member.

What I claim as my invention is:

1. An index for a page of a book comprising a strip of material folded to form an interior approximately U-shaped body and bent backwardly and outwardly to form exterior substantially parallel side members extending beyond the U-shaped body one of the side members being provided with an approximately L-shaped extension forming an outer U-shaped portion and overlapping the other side member.

2. An index for a page of a book comprising a strip of material folded to form an interior approximately U-shaped body and bent backwardly and outwardly to form exterior substantially parallel side members extending beyond the U-shaped body one of the side members being provided with an approximately L-shaped extension forming an outer U-shaped portion and overlapping the other side member and a metallic clip embracing the inner'U-shaped body and arranged between the same and the exterior side members." t

An index for a page of a book comprising a strip of transparent material folded to form an interior approximately U-shaped body and bent backwardly and outwardly to form exterior substantially parallel side members extending beyond the U-shaped body one of the side members being provided with'an approximately L-shaped extension forming an outer U-shaped portion and overlapping the other side member and a lining secured within the outer U-shaped portion and having an index character.

4:. An index for a page of a book comprising a strip of transparent material folded to form an interior approximately U-shaped body and bent backwardly and outwardly to form exterior substantially parallel side members extending beyond the U-shaped body one of the side members being provided with an approximately L-shaped extension forming an "outer ll-shaped portion and overlapping the other side member, a

lining secured within the outer U-shaped portion and having an index character and a metallic clip embracing the U-shaped body and arranged between the same and the side members. 7 V

Signed by me at Chicago, Cook county, Illinois, this 29th day of July, 1919.
