INDEX CARD.

Application filed July 30, 1926. Serial No. 125,974.

card in a partly exposed position without the liability of its dropping downwardly between the other cards of the system.

A further object of the invention is to provide an index card in which the holding means is formed from a part of the card itself.

A further object of the invention isto provide an index card which is of simple construction, is strong and durable and is well adapted for the purpose described.

lVith the above and other objects in view, the invention consists of the improved index card and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a side view of one of the improved index cards;

Fig. 2 is a vertical sectional View thereof taken on line 22 of Fig. 1; and

Fig. 3 is a vertical sectional detail view of a number of the index cards within a box,

one of said cards being shown in its upper position of use.

Referring to the drawing, the numeral 5 indicates an index card which may be of any desirable shape or size, and is provided with a curved cut 6 to form a downwardly extending tongue 7. The tongue is formed medially of the length of the card and a short distance from the lower edge portion of the card, and is preferably bent rear- Fig. 3.

wardly to form a shoulder 8 which will rest upon the upper edge of the adjacent rear card when it is desired to maintain the card in partly exposed position, as indicated in When the tongues are bent outwardly in the manner shown, they will yieldingly maintain said position, and when the desired card is pulled upwardl the tongue 7 will snap outwardly to hold the card in an upper position. To push the card downwardly between'the other cards, it is only necessary to press the tongue inwardly into alinement with the card, and the card may be pushed downwardly between the other cards.

It is also to be understood that the card may be used in an upsidedown position, and when thus used the tongue would support the next adjacent card.

From the foregoing description, it will be seen that the index card is of very simple construction and is well adapted for the purpose described.

What I claim as my invention is:

1. An index card having a cut portion midway of its length and adjacent its lower edge portion to form a downwardly and outwardly projecting tongue for supporting the card in a raised position when placed between other cards.

2. An index card having a. downwardly curved cut portion midway of its length and adjacent the lower edge portion of the card to form a yielding downwardly and outwardly projecting tongue for supporting the card in a raised position when placed between other cards.

8. An index card having a curved portion cut from the card and adjacent its lower edge to form a downwardly and outwardly projecting tongue for supportin the card in a raised position when placed between other cards and with the tongue extending over and resting upon the upper edge of the next adjacent card.

In testimony whereof, I affix my signature.

STEPHEN C. RADFORD.
