UNITED STATES PATENT' OFFICE.
JAMES GRAHAM, OF DETROIT, lVHOHIGAN.
READING GLASS OR LENS.
SPECIFICATION forming part of Letters Patent No. 547,114, dated October 1, 1895.
Application filed. May 27, 1895. Serial No. 550,881. (No model.)
To all whom it may concern.-
Be it known that I, JAMEs GRAHAM, a citizen of the United States, residing at Detroit, in the county of WVayne and State of Michigan, have invented a new and useful Reading Glass or Lens, of which the following is a specification.
My invention relates more especially to i1nprovements in that class of magnifying-lenses held in the hand while reading-"an inconvenience I propose to obviate. This inconvenience is more especially felt when the reader is traveling by rail and subject to a constant succession of jars, which renders it very difficult to keep a proper focus. I minimize this difficulty and also the necessity of constantly moving the hand back and forth across the page by the following device, in which- Figure 1 represents my preferable form of lens with its fastening attachment in place on a book and ready for use. Fig. 2 shows the fastening-rod on which the lens slides, detached. Fig. 3 is another form of the same.
By preference the lens is made in oblong form of about the ratio of one to three, To the corners of the frame, at right angles to the plane of the lens, are attached the focal guides a. They are designed to keep the lens a proper distance from the paper and are projected alike on each side of the lens, so that when the lens is turned to either page of an open book it has a focal guide. In the center of one end of thelens-frame is a lug d, with a bore inthe same adapted to slide on a rod B, the upper end of which rod is flattened and bent over at C until it is parallel to the rod tempered as a spring and ending either in a pin (f) or blade (f') shaped point adapted to be easily slipped between the leaves of a book. It may also be provided with a hinge b at the point where it is flattened, for greater convenience in slipping the blade or pin between the leaves of a book.
a is a lip or piece on which the'finger may be placed while slowly moving the lens down the page.
The rod may be made with an extension 6,
so that it can be adapted for along page without increasing the length of its case. Its adaptation for the purpose intended is obvious, It can be fastened into a book on either side of the center and drawn down while reading; then, without releasing the rod, the lens can be turned over to the opposite page, and so on.
What I claim, and desire to secure by Letters Patent, is-
1. A reading lens constructed to cover a page of printed matter in width and one or more lines in depth, a guiding member to which said lens is attached and on whichit is adapted to slide, said guide so arranged as to be fastened at the top of the paper or book and to allow the lens to be turned to either side or page for use without disturbing the guide, substantially as described and for the purpose set forth.
2. A reading lens constructed to cover and magnify a column orpage of printed matter in Width, and one or more lines in depth,having focal guides attached to keep the lens a proper distance from the paper and adapted to slide or move down the page, a guiding member for the focal guide, said member adapted to be fastened at the top of the book or paper substantially as described and for the purpose set forth.
3. A reading lens of oblong shape c0nstructed to cover and magnify a column or page of printed matter in width and one or more lines in depth, having focal guides attached to keep the lens a proper distance from the paper, and adapted to slide or move down the page, a guide on which it moves, the guide so arranged as to be fastened to the top of the book or paper, and to allow the lens to be turned to either page for use without disturbing the guide, substantially as described and for the purpose set forth.
