Serial No. 291,713.

To all whom z'zf may concern Be it known that l, PAUL W. HrnsoH, a citizen of the United States, and residing at Redford2 in the county of Vayne and State of Michigan, have invented a new and Improved Chair, of which the following is a specication.

This invention relates to chairs and more particularly to those suitable for use in restaurants or other eating places such as dairy lunches where the dishes of food have heretofore been supported by a wide arm of the chair while the patron is eating his lunch.

Heretofore it has been necessary to place the food on one or both arms of a chair but my invention has in mind a movable arm for one side of the chair which can be swung around across the front so that the food will be supported by an adjustable arm in front of the diner instead of at his side as is the case with the present chairs on the market in which the food is placed on Va fixed arm at one side of the chair.

Another object is to provide an apparel hook for the chair on which may be hung apparel of the occupant of the chair, if desired.

Further objects are to accomplish the above with as simple and economical design as possible and in a way such that present chairs, now in use, can be supplied with my adjustable arm.

With the above and other incidental objects in view my invention further consists in various details of construction and combinations of parts hereinafter more fully described in connection with the drawings which accompany and form part of this specification, and subsequently pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a lunch chair with my invention applied. Fig. 2 is a similar view but with the adjustable arm shown in position at the front of the chair. Fig. 3 is an enlarged plan view of a portion of the chair, with parts broken away to better showthose beneath, and showing by dotted lines, the position of the arm when in front of the chair.

Fig. 4 is an elevation of my attachment showingits connection with the chair post. Fig. 5 is a perspective view of the supportin bracket., Y

he chair shown may be of any well Specification of Letters Patent.

known type provided with no arms whatever. I apply my invention thereto by supporting all the mechanism of it from one of the front legs 1 preferably the right hand one. 2 is a supporting bracket forA my attachment which is merely a casting having a foot 3 curved at l to fit the leg of the chair. An opposing gripping member 5 is pivoted at 6 by a hinge connection with the foot 3 and both this gripping member 5 and the foot 3 are provided with ears 7 apertured to receive a clamping bolt 8 which, by means of a cooperating nut 9is usedl to tightly grip the foot 3 and hinged member 5 around the right hand forward chair leg l at any height desiredvrlhe upper end of the bracket 2 is provided with'an integral flat top 10 extending from the right of the chair, the base of which top portion has eX- tending beneath it an integral supporting web 11 for strength. The shape of the flat top of the bracket 2 can be traced very Well from Figs. 1 to 3 and is made of sulficient area to provide a substantial support and slide for the adjustable arm. This top surface 10 of the bracket is provided with a couple of holes 12 down through which from the top extend bolts 18 having a portion 14 of a little larger diameter than the hole in the top of the bracket 10 and having above this portion 141 a head 15 of still larger diameter. These bolts 13j are fastened to the top 10 by nuts 16 screwing on their lower ends so as to hold the bolts in place. The portions 14: of the bolts being of greater diameter than the holes in the top lOforn o t e bracket 10. The heads 15 of the bolts being still larger in diameter are thus separated Vfrom the top of the bracket by suiiicient a sliding member space for the thickness of now to be described.

17 is a supporting plate for the arm proper of my chair and the shape. of this arm can be readily traced.v from the drawing. The thickness of this plate is just sufficient to lit between the heads 15 of the bolts 18 and the top 10 ofthe `bracket 2. This top 10 slidably supports the plate 17 and the latter is provided with two slots 18 through which bolts 13 are passed in assembling the parts on the top of the bracket 2. When this plate 17 is thus mounted on the top 10 of the bracket 2 and the bolts 13 passed through the slots 18 and the holes l2 and fastened in place, it will be seen that the plate 17 can slide, supported by the top 10, and that the heads of the bolt projecting over the edges of the slot 18 will retain the plate 17 in place on the bracket top. Thus the top 17 then is free to have either the full line relationship of Fig. 3 at the right of the chair with the bolts 13 at the forward end of the slots 1S, or it may have the dot and dash line relationship at the front of the chair in Fig. 3 with the bolts 13 at the other end of the slots 1S. It is of course obvious that the plate 17 may occupy any position intermediate these two e3- tremes.

lWhile I might make use of the plate 17 as a supporting plate for the dishes of food by not having the slots 13 extend through it but only undercut from the bottom still I prefer, in practice, to have this plate support a top plate for the real arm of the chair for supporting the dishes of food. Thus I have shown a top plate 19 which may be of wood, aluminum, or any desired material. The shape of this plate appears clearly from Figs. 1 and 2 from which it will be seen to extend at least slightly overthe periphery of the plate 17. In order that the plate 19 will be carried sufficiently above the plate 17 so as to provide clearance for the heads 15 of the bolts 13 I support it from the plate 17 through the medium of blocks 20 located at various points on the upper surface of the plate 17 and through which are adapted to pass, from the under surface of the plate 17, screws 21 for securing the parts 19, 20 and 17 together. The holes in the plate 17 are countersunk from the underside so that the heads 22 of the screws 21 will, when the latter are completely in place, be flush with the bottom surface of the plate 17 so as to form no obstruction against the sliding of the plate 19 over the top surface 10 of the bracket 2. Thus the parts 19 and 17 are in effect one so far as operation is concerned, and these two together with their connecting elements form the adjustable chair arm, these parts sliding when desired over the surface of the top 10 of the bracket 2. guided by the bolts 13 which in coperation with the slots 18 determine the path through which the adjustable arm is to pass. The length of the slots 18 of course determines the extent of adjusting movement over which the arm may pass. A

In Fig. 2 I have indicated at one corner of the chair at the back a vertical apparel hanger 23 which may be mounted on the back of the chair by screws or other means, and this I preferably provide at the top with a hook 24 adapted to receive any article of apparel desired to be disposed of temporarily while one is using the chair for his lunch. This provides for keeping his a parel within sight so that it will not be m any danger of being intentionally or unintentionally taken by other parties.

It is believed that the operation of my invention will be clear from the above description. It may be briefly stated, however, that generally in using a chair with my invention applied, the dishes of food will be placed upon the top plate 19.0f the adjustable arm with it in position shown in Fig. 1 before the patron sits down in the chair. After he sits down and has placed his desired apparel upon his individual hook 24- at the back of the chair all that is necessary to bring his food around to the front of him for more convenient eating, is for him to catch hold of the plate 19 and slide it forwardly, which movement owing to the shape of the slots 1S, will be effective to position the arm 19 with his food at his front as shown in Fig. 2. The bracket 2 does not move in these operations but remains fixed as a .convenient and substantial support for the adjustable arm for the chair. lVhen the patron is through eating the arm is easily shifted back to the position at the right of the chair shown in Fig. 1 permitting more convenient arising of the patron from his chair.

From the drawings it will be clear that the shape of the arm and coperating parts and the radius and relationship of the slots 18 is such that the adjustable arm in swinging from one extreme to another, never projects at one time farther to the right of the chair than at any other time. By this construction the danger of interfering with the user ofthe next chair to the right is eliminated-and the necessary space between the chairs is therefore kept down to a minimum.

It will be observed that my invention has been .applied in a very simple and efficient way suitable for application to the old form of chairs now in use as it is for application to the new form of chairs. While very simple in construction it is likewise eflicient in service. I have shown a preferred forni of construction but I do not mean tov be limited thereto except as required by the scope of the appended claims for the reason that various changes and modifications may readily occur to those skilled in the art all coming within the principle of my invention as herein disclosed.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device of the class described comprising the combination of a supporting bracket, adapted to be secured to the side of a chair; an arm, slidable on said bracket, said arm having, on its lower surface, a pair of parallel tracks curved around a center disposed above the seat of the chair, said tracks being substantially parallel to the outer edge of said arm; and guide members, Acarried by said bracket and cooperating With said tracks to limit the movement of the arm to a path predetermined by the curvature of the tracks.

2. The combination with a chair, of a supporting bracket carried thereby; an arm slidable thereon; a pair of concentric arcuate tracks carried by said arm; guide members, carried by said bracket, and coperating With said tracks to limit the movement of said arm to a swinging movement about an axis disposed over the seat of said chair.
