Specification of Letters Patent.
Application filed August 12, 1911.
Patented May 14, 1912. Serial No. 643,719.
To all whom it may omtcern.
Be it known that I, JOHN S. MAXWELL, a citizen of the United States, residing at Anadarko, in the county of Gaddo and State of Oklahoma, have invented new and useful Improvements in Book-Holders, of which the following is a specification.
This invention relates to book holders and the object of the invention is to provide a simple and cheaply constructed book holder which may be folded so as to occupy small space and which, when set up, will hold a book at the desired inclination for reading or studying.
A further object of the invention is the provision of a device of this character having the supporting legs so constructed that they will clamp the book in positionand prevent the leaves from accidental turning.
Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure l is a perspective view of the device. Fig. 2 is a front elevation of the device in folded position. Fig. 3 is an edge elevation.
In the specific embodiment of the invention illustrated herein, the device consists essentially of three members, a top member, two supporting and clamping legs and a supporting strut. The top member is indicated at 1 and preferably comprises a single strand of wire having its intermediate portion depressed in the form of a journaling loop 2 and its endsformed into coils 3 with the terminals of said coils arranged to form limiting stops 4:, as will be hereinafter understood. Pivoted upon the member 1 within the loop is a strut 5 whose upper end is coiled around the loop and has its terminal forming a limiting stop 6 which engages one leg of the loop to prevent excessive rearward movement. The opposite end of the strut is bent laterally in the form of a supporting foot 7 and surrounding the same is a tube 8 of frictional material.
The supporting legs consist of single pieces of wire which are passed through the coils 3 and bent back upon themselves, as shown at 9, their terminal ends being bent beneath the coils and being adapted to engage the terminal ends of the coils to limit the turning movement of the legs. The opposite ends of the legs are curved upwardly and inwardly to form clamping members 10 and their terminals are upwardly bent so as to lie substantially parallel with the legs and prevent the same from tearing the leaves of the book. These legs are also supplied with frictional tubes 11 which prevent the device from slipping upon the supporting surface. 4
In folding the device the legs are rotated in the coils until the bent back portion 9 engages the top member 1. The strut is then folded inwardly until it lies in the same plane with the legs and top member. It will thus be seen that a substantially fiat device is produced which, if necessary, can be conveniently carried in the pocket without occupying any considerable space.
Having thus described the invention, what I claim as new is A device of the class described comprising a top member having right angular coils formed at its ends, a central pivoted loop, legs passing through said coils and journaled therein, the ends of said legs being bent back parallel with their bodies, and having their terminals extending beneath the coils and adapted to engage the terminal ends of the coils to limit the movement of the legs in one direction, the opposite ends of the legs being curved upwardly and inwardly to form spring clamping members, a supporting strut pivoted in the loop, and frictional members carried by the strut and supporting legs for preventing the device from slipping, said supporting legs and strut being adapted to fold in a common plane with the top member and loop.
In testimony whereof I afiiX my signature in presence of two witnesses.
JOHN S. MAXWELL.
