ADJUSTABLE SUPPORT FOR BOOKS, PAPERS, ac.

To all whom it may concern:

Be it known that 1, CHARLES T. Ham of East Liverpool, in the county of Columb1ana and State of Ohio, have invented certaln new and useful Improvements in Adjustable Supports for Books, Papers, &c.; and I do hereby declare the following to be a full, clear, and exact description of the inventlon, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in adjustable supports for books, papers, etc., and more particularly to such as are adapted for attachment to the arm of a chair, the object of the invention being to provide a support of the character described which shall be simple and light in construction; which can be folded into compact form; which can be easily and quickly attached to the arm of a chair without injury to the latter and adjusted to any position to suit the convenience of the user; which can be cheaply manufactured without detracting in any way from its efliciency, and which will provide means for holding the covers of a book and also means for holding the leaves of a book.

With these objects in view the invention consists in certain novel features of con struction and combinations of parts as hereinafter set forth and pointed out in the claim.

In the accompanying drawings,Figure 1 is a view showing the application of my invention. Fig. 2 is a side elevation partly in section. Fig. 3 is a view in section showing the adjustable book supporting devices. and Fig. 4 is a view illustrating the book support in its folded position.

1 represents a tubular post preferably having at least one fiat face 2 and provided at its lower end with an integral laterally projecting portion which constitutes a fixed jaw to be disposed under the arm of a chair. An arm 3 is vertically movable on the post- 1 and is provided near its free end with a threaded hole for the passage of a screw 4 having a cross-head or other hand engaging means 5 at its upper end. A padded jaw 6 is swiveled to the lower end of the screw 4 and cooperates with the fixed jaw 7 to form a clamp. The padded jaw is made to engage the top surface of the arm of a chair by moving the arm 3 downwardly. The arm 3 will now be held to the post 1 by frictional Specification ofLetters Patent.

contact and be prevented from turning on the arm of the chair, at the same time increasing the frictional contact between the vertically movable arm 3 and the post 1.

The lower port-ion of a bent standard 8 is revolubly mounted in the post 1 and may be prevented from removal by means of a pin passing through the post and through an annular groove in the standard. A bracket 9 is revolubly mounted on the upper end of the standard 8. Removal of the bracket 9 from the standard is prevented by means of a pin 11 passing through the former and engaging in an annular groove in the latter. The bracket 9 supports a bar 12 having an elongated slot 13 for the passage of a screw 14,said screw being provided at one end with a head to engage one face of the bar 12. The screw 14 passes through the elongated slot of the bar 12 and through the bracket 9 and at its free end is threaded for the reception of a thumb nut 16. By these means the bar 12 can be adjusted to different vertical positions and at different angles and be secured in any position on the bracket 9 to which it may be adjusted. The bar 12 is provided at its upper or front edge with a laterally projecting flange 17 which terminates at its respective ends short distances from the respective ends of said bar. Two angular arms 18 are pivotally connect ed together and to the laterally projecting flange 17, near the lower end of the latter, so that the depending members of said angle arms will engage respective faces of the bar 12 and retain said arms in a horizontal position. Each arm 18 is provided with a lug or project-ion 19 which may be formed integral with said arms and constitute sup ports for the book or other article that may be placed upon the device. The outer end of each arm 18 is ofiset and then bent upwardly to form lugs or integral clips 10 disposed short distances forwardly from the front faces of said arms and constitute holding means for the covers of a book while the lower end of the latter is resting on the lugs or projections 19.

In order to hold the book open and prevent the accidental turning of the leaves, spring clips 20 are provided. These clips are carried by the arms 18 and each clip 20 comprises a wire spiral 21 disposed parallel with the lug or projection 19 on one of said arms and having its inner end secured to said lug or projection,the wire being extended from the outer end of the spiral to form an arm 22 which projects beyond the lug 19 and terminates in a finger 23 projecting upwardly over the arm 18 so as to be in position to press against the leaf of a book resting on the support' The upper portion of the book or other article will be supported by angular arms 24: pivotally attached at their inner ends to the upper portion of the flange 17 of bar 12 and one member of each of these arms is adapted to engage the bar 12 near the end of the latter.

The bracket 9, the bar 12 and all of the arms 18 and 24: may be made of sheet metal and hence the device will be light in weight,

easy to construct but have sufiicient strength to properly support in any of the positions to which it may be adjusted, a book or other article of considerable size and weight.

Then the device is not in use the arms 18 and 2 1 can be folded so as to interlock and be disposed over each other and over the bar 12 as shown in Fig. 4-, thus reducing the device to small compass.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

In a book support, the combination with an upright member, and supporting means therefor, of arms made angular in cross section and attached at their inner ends to the lower portion of said upright member, each of said arms provided intermediate of its ends with integral projections to support a book and each arm provided at its outer end with an integral fixed clip spaced outwardly from the upright face of the arm, and spring clips secured to the bottom faces of the book supporting projections and having their free ends terminating substantially parallel with the upright portions of the arms between said supporting projections and the fixed clips at the outer ends of said arms.

In testimony whereof, I have signed this specification in the presence of two subscril ing witnesses.
