GEORGE S. LEWIS, OF ROCHESTER, NEW YORK- LEAFED ARTICLE.

T 0 all whom it may concern:

Be it known that I, GEORGE S. Lnwrs, a citizen of the United States, and resident of Rochester, in the county of Monroe and ate of New York, have invented certain new and useful Improvements in Leafed Articles, of which the following is a specification.

The present invention relates to leafed articles, such for instance, as books, indexes, files and the like, and an object thereof is to provide a leafed article which may be opened to any desired page by a pull upon the cover or foremost leaf of such article. Another object of the invention is to provide an article which will perform the foregoing function and which is inexpensive to manufacture, simple in operation, and du- Table in use.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims. J

In the drawings:

Fig. 1 shows the leafed article embodied in a telephone index and attached to a telephone;

Fig. ,2 is an enlarged plan view of the index illustrated in Fig. 1; and

Fig. 3 shows the index open and in side elevation.

Referring to the embodiment of the invention herein illustrated, 1, 2, 3, 4, 5 and 6 indicate the leaves of the article. The leaves are hinged together in such a manner that a pull upon the foremost leaf will be transmitted to all of the leaves of the book, unless restrained for the purpose of swinging said leaves on the hinge of the rearmost unrestrained leaf. By this arrangement, should it be desired to open the book at any one page, it is merely necessary to restrain the leaf at such page and the other leaves will swing upon the hinge of the rearmost unrestrained leaf when a pull is applied to the forward or uppermost leaf. This result is accomplished by hinging each leaf to the leaf nextin rear thereof at a point in spaced relation to the hinge of such next leaf. A simple way of effecting this hinging is to project each leaf beyond the one next in front of it as at 7 and adhesively secure a -With thee'nd in binding piece or strip 8 to the projecting portions. view ofrestraining the Specification of Letters Patent.

movement of any desired number of leaves the form of a flexible cord which may be passed about the mouth piece of a telephone transmitter for the purpose of suspending said index, while at the same time providing means through which a pull on the forward leaf may be obtained.

In using'the invention when embodied in an index for telephones, the pulling and suspending cord is passed about the mouth piece and the leaves depend from such mouth piece. When it is desired to open the index at any letter, the thumb of one hand is placed upon the extension 9 containing the letter, and a pull on the leaves in rear of the thumb will effect a pull on the forward or front leaf 1 and this pulling will be transmitted through the hinge connection to all of. the leaves which are not restrained by the thumb. A

From the foregoing it will be seen that there has been provided a leafed article or book in which the article may be opened automatically to any desired page, merely by indicating with the thump or finger, the page at which it is desired 0 open the article and pulling upon the forward leaf, the pull being transmitted to all those pages between the front leaf and the leaf indicated and restrained by the thumb or finger.

What I claim as my invention and desire to secure by Letters Patent is:

1. A leafed article having leaves which .are hinged, one to the next in rear thereof at a point removed fromv the hinge of the leaf in rear thereof so that a pull on the foremost leaf will be transmitted to an desired number of leaves in rear of suc foremost leaf, and each leaf having a p ortion at a distance from its hinge projecting beyond the leaf next in front of such leaf through which the leaf last to be affected by the pull is determined.

.3. A leafed article comprising a plurality of leaves, each of which projects beyond a leaf next in front of it, and binding and hinging material secured over the projecting portion and providing for the independent swinging of any desired number of leaves relatively to the leaves in rear of such member by a pull on the foremost leaf.

4. A leafed article comprising a plurality of leaves, each having two portions projecting beyond the leaf in front of it, means hinging each leaf to the leaf next in rear of bottom edges of a lower portion of said stack can be moved; and means by which said movement forces the bottom edges of the upper portion of the stack upwardly to expose the top card of said lower portion of said stack.
