CHARLES E. SEBASTIAN AND HERMAN STOEBE, OF NEW YORK, N. Y.

LEAF-RAISER FOR BOOKS.

SPECIFICATION forming part of Letters Patent N0. 757,779, dated April 19, 1904:. Application filed January 23, 1904. Serial No. 190,315. (No model.)

To all whmn it may concern.-

Be it known that we, GHARLns E. SEBASTIAN, a resident of the borough of Manhattan, county of New York, and HERMAN S'roEBE, a resident of the borough of Brooklyn, county of Kings, city and State of New York, citizens of the United States, have invented certain new and useful Improvements in Leaf-Raisers for Books, of which the following is a speci fication.

Our invention relates to a device for raising the leaves of books individually, so as to facilitate their turning.

The object of our invention is to provide a device of this character which will be simple, strong, and cheap in construction and adapted to be applied to lead-pencils or the like.

Reference is to be had to the accompanying drawings, in which- Figure l is a broken outside view of our invention, and Fig. 2 is a sectional view of the same as applied to a lead-pencil.

A designates a lead-pencil or other suitable article adapted to form a handle for the leafraiser. The device proper, as shown, con sists of three parts, although this might be varied. One of these parts is a socket B, open at one end to receive the end of the pencil or handle A. The socket may be split longitudinally, if desired, in which case it may also serve as a protector for the pointed end of the pencil. Such use is of course possible even with a solid or unsplit socket. The socket has an end wall B, against which the handle may abut, then follows a neck or contraction B, and finally a retaining member B of greater diameter than said neck. The retaining member may be in the nature of a socket for the reception of a rubber eraser C. Between the socket B and the retaining member B is held the lifting-disk D, made of rubber or like material and preferably corrugated at its periphery.

For the sake of convenience in manufacture the retaining member B its end wall B*, and neck B may be made of one piece, the neck being originally of uniform diameter. Then the lifting-disk D is applied to the neck, and the socketB is placed against the disk, so that the end of the tubular neck B projects through a central opening in the end wall B of the socket B. Then the end of the neck B is upset after the manner of an eyelet, as shown as B and this completes the connection of the parts. Instead of this construction the neck B might be made in one piece with the socket B and end wall B. In this manner a very strong device is obtained, yet the construction is simple and inexpensive.

The device is used by pressing the liftingdisk D against the leaf which it is desired to raise and then moving the entire device toward the crease or back of the book and preferably at the same time imparting a rotary motion to the device.

Various modifications may be made without departing from the nature of our invention.

What we claim, and desire to secure by Letters Patent, is

1. A leaf-raiser for books, comprising a socket, a retaining member, a neck connecting said socket and said retaining member, said neck being of smaller diameter than either the socket or the retaining member,and a liftingdisk surrounding said neck, said lifting-disk being engaged and clamped by the opposing faces of the socket and the retaining member.

2. A leaf-raiser for books, comprising two members, one of said members having a reduced neck projected therefrom, and the other member having a socket formation to receive the end of said neck, and a lifting-disk surrounding said neck.

3. A leaf-raiser for books, comprising two members provided with inwardly-turned walls at their opposing ends, a reduced neck con necting said walls, and a liftingdisk surrounding said neck.

In testimony whereof we have signed our names to this specification in thepresence of the subscribing witnesses.
