Application led August 18, 1908. I Serial No. 449,082. V

To all whom it may concern:

Be it known that I, DAVID 'MCGENNIss, citizen of the United States, residing at Winston Salem, vin the county of Forsyth `and State of NorthI Carolina, have invented certain new and useful Improvements in Chair Attachments, of which the following is a speciiication.

This invention has for its object, an improved construction of book rest or 4table attachment for chairs, benches or t-helike, the parts of which are of simplel and durable construction, and capable of being cheaply manufactured and readily assembled. And the invention consists in .certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.l

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is'a perspective view illustrating the application of one embodiment of my inventiongFig. 2 is a .sectional -view thereof; Fig. 3 is a bottom plan view ofa brace that, is attached vto the bottom surface projecting post. 2, said' post being formed with a bore 3 smooth for a portionof lits length from its upper end and threaded 'at or near its lower end as clearly@ illustrated, in the drawing.v

4 designates an angular bracket arm which is .provided at one end .withl a threaded stud or pin 5 designed to be inserted in the bore 3 of the post 2 so as to maintain the bracket arm upon thev post 2, in a manner to permit the circular sweep of the bracket arm around the post as an axis. The height of the bracket arm relative to the post 2 and the base 1 may obviously be varied owing to the screw threaded engage'- Vment of the stud 5 with the bore 3, while at the same time the sweep of the bracket arm around the post as an axis is permitted sol u as to bring the bracket arm in the desired position. The threaded engagementbetween the stud of the bracket arm and the post 2 also holds thebracket arm and base connected together so that the device may be carried from place to place as desired without having the-base-detached from the bracket arm, 1t being understood that t-he embodiment of the invention which includes the base 1 is a portable device. The bracket arm 4 is formed at its upper end with an upstanding dowel 6, and an annular shoulder 7a at-the base of said dowel, the dowel being designed for insertion in any one of a plurality o f sockets 8 and 9 formed in a brace 10 which is composed of a casing with divergentarms 'screwed or otherwise secured to a'lower face of a leaf 11 which constitutes the'table top or bo'okl rest proper.

'The socket 9 extends substantially perpendicular to the leaf 11, while the socket 8 is obliquely disposed'thereto, so that the leaf may be positionedin a horizontal plane on the dowel whenit is used as a table top, or'

may with equal facility be held at an inelinationito the horizontal so as to serve as a book rest.

Preferably the lower face of the base 1 .is

. covered with felt 12 or some other material l s o as to prevent the base from scratching the sides 'of a chair o r bench upon which it is placed.

In-the practical use 0f that embodiment of'my invention hereinbefore described, the base 1 vis placed onthe side of a chair under the left or right leg of the occupant of the chair between-the lhip and the knee, the entire device being thus held -in proper position so that the leaf-l1 may be swung over in front moved from place to place and 'used without any permanent attachment to a chair or table,

thereby not only facilitating the use of the device wherever the owner happens 'to be, but at the same time avoids the necessity of marring the article of furniture to which it is temporarily applied.

If` desired,-I may use in connection with the bracket arm and leaf as before described, a relatively stationary base l which is formed with a post 2a for the reception of a threaded stud 5, the bore of said. post l being smooth, however, so that the bracket arni may be readily detached therefrom by v to swing it over in front of the person occupying the chair so as to assume the proper position for reading or other purposes; and that the device, particularly that embodi ment thereof as herein described, is a portable onewhich may be used on any chair or bench, without the necessity of'any permanent or temporary attachmentv of the base to the chair other than that caused by the weight of the person seated therein.

Having thus described the invention, what is claimed as new is:

A device of the kind described, comprising an angularly formed bracket arni having at one end a shoulder and a downwardly projecting stud screw-threaded -at its end and extending` beyond the shoulder, the other end of said bracket arm being provided with an upwardly projecting vertical dowel or pin, in combination with a base, a hollow post carried by said base for the reception of said stud, the said post being screw-threaded on its interior for engagement with the screw threaded extremity of the downwardly projecting stud on the bracket arm, and a table oi leaf having a downwardly projecting hub vattached to its under side, said hub being formed with a socket extending at right angles to the leaf, and an adjacent socket extending in a direction less than a right angle thereto, each of said sockets being adaptedto fit over and. receive said dowel, whereby the leaf may be placed in either horizontal or inclined osition.

In testimony whereof I ailix my signature in presence of two witnesses. DAVID MCGENNISS. [n s] Witnesses :v
