Among other purposes and advantages,the The head 10 of the bed comprises the usual 55 invention has for its objects: to provide a side member, post or upri ht 11, to which the tray and connections readily attachable to supporting connections or the tray 12 are and detachable from the frame of a bed; to adapted to be attached. These supporting provide connections so that the tray may be connections comprise a bracket 13 adapted readily moved to various positions with reto be secured to the post 11, and, when do spect to the occupant of the bed so as to be sired, to be'detached therefrom. .The bracket conveniently and comfortably used as aread- 13 may be slid or adjusted up or downon ing desk or as a dining tray or the like and the post lland held in any desired position so that the tray may be moved to another of verticaladjustment by turning the wing 5 position or positions clear of the occupant nut-14.- of the bolt or screw that secured the of the bed and clear of the bed so as to facilipivoted halves of the bracket 13 together. tate making the bed; to provide a tray and onemember 15, of a telescoping arm 15-16, connections of the class referred to which are is plvotally connected to the bracket 13 for wholly supported from the bed so as not to swinging movement about a vertical axis and increase the number of legs or supports restalso for swinging movement about a horiing upon the floor and thereby impede sweepzontal axis. By virtue of the swinging moveing, mopping, or cleansing of the floor; and ment about the vertical axis, the tray 12 may to provide a tray and connections of the class be swung in a substantially horizontal plane described particularly adapted for attachtoward and away f m he bedand its occu- 5 ment to hospital or sick beds, such as sopant, and by virtue of the swinging movecalled Gatch beds, without interfering ment about the horizontal axis, the tray'a with the ready adjustment of such beds in the 155' connections may be swung down to be usual manner.

Fig. 5 is a section taken on the line 5-5 The telescoping arms 15-16 are shown as 50 of Fig. 4. square in cross-section so as to prevent turnnally to lengthen or shorten the arm 1516 and held in any desired position of such adjustment by turning the winged head 22 of a set screw which is threaded in the arm 15 and adapted to engage the arm 16. Preferably the arm 16 is provided with a square head 23 and the arm 15-is provided with a hollow square bushing 24 which provide bearings for the relative sliding movement of the arms 1516, but prevent the arms 1516 from being completely separated.

The outer arm 16 of the telescoping arms 1516 is provided with a vertical pivot pin 25 about which the hollow arm 26 is adapted to swing. The end of the arm 26 that surrounds the pin 25 is shown provided with a set screw whose inner end extends into an annular groove provided in the pin 25 (see Fig. 6) and whose outer end is provided with a winged head 27. By means of the winged 'head 27, the last mentioned set screw may be unscrewed to such extent as to permit separation for dis-assembly of the arms 16 and 26, the set screw may be screwed in to such an extent as to prevent separation of the arms 16 and 26 while permitting swinging or adjustment of the arm 26 about the vertical axis of the pin 25. and the set screw may be screwed in still further, if desired, to hold the arms 16-26 in any desired relative position with respect to the vertical axis of the pin 25; it being understood, of course, that the last mentioned adjustment need not be employed in view of the fact that friction and inertia will serve to hold the arms 16 and 26 in any relative position with respect to the vertical axis of the pin 25.

Theother end of the hollow-arm 26 forms a socket for a vertical pin 28 integral with one of the halves 29 of a serrated bracket whose other half 30 is secured to the tray 12. The serrated bracket 2930 is quite similar to the bracket 17-18 and, like it, is provided with a set screw which extends through the half 29, screwsinto the half 30, and has a winged head 31 b means of which the two halves of the brac et may be held in any desired position of adjustment. The pin 28 is shown provided with an annular groove, like that of the pin 25, and the upper or outer end of the hollow arm 26 is shown provided with a set screw 32 like the set screw 27, above described.

. In view of the foregoing it will be underand held in any position of such adjustment by tightening the screw 21; the tray 12 may be swung with respect to the bed to various positions about the vertical axis of the pin 20; the tray 12 may be swung to various ositions about the axis of the pin 28 and, i desired, ripped in any of these adjusted positions by screwing the screw 32'tightly home; and the arm 26 and the tray carried thereby may be swung to various positions about the axis of the pin 25 and, if desired, gripped in any of these adjusted positions by screwing the screw 27 tightly home. Furthermore, the distance between the tray 12 and the post 11 (or the pin 20) may be varied by shortening or lengthening thetelescoping arms 15--16 and when this adjustment has been eifected, it may be held by turning the'screw 22. In addition, the entire assemblage may be raised or lowered on the pst 11 and held in its position of such adjustment by turning the screw 14. Moreover, the tray and its supporting connections may be readily detached from the bed by removing the bracket 13 from the post 11.

It will be seen that by virtue of the abovedescribed structure I have provided a tray andsupporting connections which are comparatively simple in construction and operation; readily attachable to and detachable from a bed; adjustable to a variety of positions to accommodate use by an occupant of the bed; collapsible, foldable, and adjustable to positions so as notto be in the way when not in use; and which are strong and reliable.

The tray 12may be made of wood and the other parts of metal, although other materials may of course be employed.

It is to be understood that the invention is not limited to the specific embodiment herein illustrated and described but may be used in other ways without departure from its spirit as defined by the following claims.

hat I claim is: i

1. An attachment for beds and comprising in combination. a bracket adapted to be secured to an upright of a bedstead, an arm pivotally connected to said bracket for adjustin g movement about a horizontal axis substantially at right angles to said arm, manually settable means whereby said arm may be held in anv one of a plurality of selectable positions about said horizontal axis, each of which selectable positions diflers from the adjacent one by a relatively small angle, a secon d arm pivotally connected to said first men tioned arm for pivotal movement with respect thereto about'a substantially vertical axis, a tray, means connecting said second arm and tray for relative pivotal movement about a substantially vertical axis, means connecting said tray and second arm for relative pivotal movement about a substantially horizontal axis, and manually settable means for holding said tray in'any one of a multiplicity of selectable positions about said last mentioned horizontal axis whereby the tray may be leveled or adjusted to an inclined reading position.

2. An attachment for beds and comprising in combination, a bracket adapted to be socured to an upright of a bedstead, an arm pivotally connected to said bracket for adjusting movement about a horizontal axis subrespect thereto about a substantially vertical axis, manually settable means for bolding said second arm in various positions of adjustment with respect to said first mentioned arm about said last mentioned substantially vertical axis, a tray. means connecting said second arm and tray for relative pivotal movement about a substantially vertical axis, manually settable means for holding said second arm and tray in various positions of adjustment about said last mentioned substantially vertical axis, means connecting said tray and second arm for relative pivotal movement about a substantially horizontal axis, and manually settable means for holding said tray in any one of a multiplicity of selectable positions about said last mentioned horizontal axis whereby the tray may be leveled or adjusted to an inclined reading position.

In testimony whereof I hereto atfix my signature.

JOHN H. HAYES.
