INDEX CLIP Filed July 14, 1937 flifo rnez/ Patented May. 24, 1938 UNITED STATES "earns OFFICE Claims.

(Granted under the act of March 3,1883, as amended April 30, 1928; 370 0. G. 757) This invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates generally to marking devices, but more particularly to an index clip which may be attached to the leaves of books, filing cards, etc.

One object of the invention is to provide a detachable clip which will be particularly adapted for use in filing or bookkeeping.

Another object of the invention is to provide an index clip of simple and inexpensive construction which may easily be attached and released from the leaves of books or cards without injuring the edges thereof.

With these and other objects in view, this invention consists in certain novel details of construction, combination and arrangement of parts to be more particularly hereinafter described and claimed.

Referring to the accompanying drawing in which corresponding parts are indicated by similar reference characters:

Fig. 1 is a perspective view of the index clip;

and

Fig. 2 is a perspective view showing the clip attached to the leaf of a book.

Briefly stated, the invention comprises an index clip consisting of a tag and a resilient engaging means connected thereto adapted for yieldable attachment to a sheet of paper, a card, leaves of a book or cloth, etc.

The resilient engaging means or clip indicated in the figures by the numeral I, consists of a single piece of resilient wire bent to form a supporting loop 2, and two partially overlapping engaging loops 3 and 4, all of which lie in a single plane when the clip is not attached to the article to be marked or indexed.

The loop 2 is preferably made in rectangular form and a tag 5 is formed with a central slit or opening 6 through which the terminals 1 and 8 of the loop 2 are threaded before the loops 3 and 4 are formed.

The terminals or extending ends 1 and 8 of the supporting loop 2 are threaded through the opening 6 in the tag 5, and the tag is folded on a line through the opening 6 along the side of the supporting loop adjacent the extending ends 1 and B, and the inner surfaces of the sides 9 and ill adhesiv-ely united to inclose between them the supporting loop 2. The extending ends of the supporting loop are bent to form partially overlapping engaging loops 3 and 4 adapted to straddle the edge of sheet material and yieldably engage the same. A clamp II in the form of a flat link is clamped around the portion of the terminals 7 and S-adjacent theloop 2, to firmly hold the overlapping loops 3 and 4 in their relative positions. If desirable in the manufacture of the device the relative widths of the opening 6 in the tag and of the engaging loops 3 and 4 may be made such that it is possible to thread the loops through the opening 6, and thus entirely complete the formation of the engaging and supporting portion of the device and the tag before assembling. The tag is folded over the straight portion of the edge of the supporting loop adjacent the extending ends 1 and 8 to allow an even pressure along the line of fold and thus avoid tearing.

To attach the index clip to a sheet of paper or a card the outer loop 4 is brought into contact with the edge thereof and the clip is then pressed slightly to spread apart the loops 3 and 4. The clip is then pressed onto the sheet so that the loops 3 and 4 straddle the edge thereof, and are retained thereon due to the resilience of the material of which the clip is formed.

Having described my invention, what I claim as new and wish to secure by Letters Patent is:

1. In an index clip, the combination of an engaging member and a tag provided with a central opening, the engaging member comprising a single piece of resilient material, bent toform a rectangular loop with projecting ends threaded through the central opening in said tag, the tag folded on a line through its central opening and its sides adhesively united to enclose said supporting loop, and the projecting ends of the latter bent to formpartially overlapping engaging loops adapted to straddle the edge of sheet material to yielclably engage the same.

2. In an index clip, the combination of an engaging member and a tag provided with a central opening, the engaging member comprising a single piece of resilient material, bent to form a rectangular loop with projecting ends threaded through the central opening in said tag, the tag folded on a line through its central opening and its sides adhesively united to enclose said supporting loop, the projecting ends of the latter bent to form partially overlapping engaging loops adapted to straddle the edge of sheet material to yieldably engage the same, and a clamp attached to projecting ends of said supporting loop adapted to retain the partially overlapping loops in their fixed relative position.

3. In an index clip, the combination of an engaging member comprising a single piece of resilient wire formed as a rectangular supporting loop with the ends of said Wire extending centrally from one of its straight rectangularly disposed sides, and a tag provided with a central opening through which the extended ends of the supporting loop project, said tag being folded centrally through the opening along the straight side of the rectangular loop adjacent said extending ends to avoid tearing by contacting an even pressure surface along the line of fold, the inner faces of the extending sides of said tag adhesively connected to inclose said loop, and the extending ends of said supporting loop bent in overlapping relation to form engaging loops providing a yieldable clamp.

' 4. In an index clip, the combination of an engaging member comprising a singlepiece of resilient wire formed as a supporting loop provided with a straight portion from which the ends of said wire extend, and a tag provided with a central opening through which the extended ends of the supporting loop project, said tag being folded centrally through the opening and along the straight side of the rectangular loopradjacent said extended ends to avoid tearing by contacting an even pressure surface along the line of fold, and the inner faces of its extending sides adhesively connected to inclose said loop, and the extending ends of said engaging member bent to form overlapping engaging loops providing a yieldable clamp.

5. In an index clip the combination of an engaging member comprising a piece of resilient wire formed as a supporting loop provided with a straight portion from which the ends of said wire extend, the extending ends of said supporting loop being bent in overlapping relation to form engaging loops providing a yieldable clamp, a tag provided with a central opening through which the engaging loops are passed, said tag being folded centrally through the opening therein along the straight portion of the supporting loop to avoid tearing by contacting an even pressure surface along the line of fold, and the inner faces of the extending sides of said tag adhesively connected to inclose said loop.
