ceiving point, but this :would entail; some labor-in assembling the trays.

v'Ihegeneral object of this invention is; to pro- :duce a trayofz-this ;type;having .a.- simple construction enabling v astiail or gsupportingglegs, to be normally held rigid 1on1 the bod .of ,=the tray, "but connected to the tray: body in, suc h-.a =wa=y that these parts can readily be disengaged-sufficiently to enable them tobeswung into substantially-the same plane as the'bodyof the tray.

In handling a traythat is carried; Qnaj bail, if articles such as glasses are removed .at one1side of the bail when servingfrom the t ra.y, ;the load remaining on the tray will be :eccentric: on the tray and would tend to swing the tray ;to one side so that the body of the tray would assume an :inclinedposition. Oneof the. objects of the invention-is to construct the .bail -of, such a tray :sQ-as to -prevent this; ,in otherawords, to construct I the -bail so 2 that, itcanreadily ,be' maintained ,in v a vertical plane ;by-the hand holding the a bail, thereby ,maintaining1the body of the tray in, a substantially horizontal position.

-A-further object of: the inventionisto produce rantarticle which can be employed-aaa tray,,and having-a bail, which, if desired,.can be held. with the bailinthe same plane as-the bodyofthe tray, to enable: the-article to :be. ,hunglipon. a wall for ornamental purposes, orlso that.the body,of

Referring particularly; to the parts, and espefcially toFigure's land 2, i indicates the body of the tray which may be ofjcircular form as indicated. At twoopposite'points, the sides of this tray are provided with shoulders capable of engaging the s ides ofthe bail 2. While one shoulder .a .e chtid th .trav e b s d..- I p e e will be evident that by pulling both extensions 4 A outwardly simultaneously, they can be readily to provide oppositely disposed substantially vertical shoulders 3 on each side, which shoulders cooperate to form a rudimentary socket 3 for receiving the adjacent end of the bail. The bail end may be in the form of an extension or ear 4 to lie against the side wall 5 of the tray when the bail is in its upright position indicated in Figure 1. When in this position, the sides or side edges 6 of the bail engage the shoulders 3land lock the body against rotation on-the bail. Any suitable pivotal connection may be provided for connecting the bail to the body 5. For this purpose I prefer to employ a pivot in the form of The bail 2 is constructed in such a way that the endsof the arms 2 and 2 of the bail; press the extensions or ears lyieldingly into the socket between the posts B In order to accomplish this, I prefer to construct the hail. of resilient material and shaped so that before the bail is applied to the tray its natural resiliency would-hold the extensions A closer togetherithan would be permitted by the presence of ;the tray body between the ears l. In the'present' instance, the bail 2 may be constructed of two bars of strap iron shaped substantially as shown and'connected together at their upper ends by a weld l2 so that the arms 2 and 2 form an angle l3; There are four of the posts 8 thereby forming a rudimentary socket on a horizontal axis between the horizontal faces 9 of the posts.

If a tray is constructed as described above, it

disengaged from the vertical sockets 3 and after beingdisen'gaged, the bail can readily be swung on the pintles I as an axis into the plane of the body of the tray as indicated in Figure 2, with tween the faces 9 of the posts 8 In order to prevent any possibility of ones fingers being pinched under the heads Ill of the pintles I, I prefer to cover each pintle with a suitable guard 14. This guard is preferably formed of a substantially tubular sleeve having a circular head l5 at one end secured to the outer side of the corresponding extension 4. Aplurality of longitudinalsllts 14 dividethe sleeve into a pluralit y of leaves M the ends of which may be bent toward each other so as to cover the outer end of the pintle.

In serving from a tray of this type, it will be evident that if a number of articles are taken off; at oneside ofthe bail, the tray will become unbalanced by an eccentric load. In that case, the tray would tend to swing laterally and assume a position in which the body of the tray is inclined.

to a horizontal plane. In order to overcome this,

I prefer to form the upper end of the bail with a handle or knob which can be grasped by the' person, carrying the trayn In. the embodiment of the invention shown inFigures 1 and 2, this can be accomplishedby forming' a handle rigid with the bail,'preferably in: the form of two rolls [5 on the ends of the arms 2 and 2 These rolls cooperate to forma handle that can be grasped in the hand that is supporting the tray, and will enable force to be applied at this point to maintain the tray body in horizontal position. In grasping the handle the angle 5 cooperates by forming a socket for fingers of the hand holding the handle.

It is advantageous to have the arms of the bail on the outer side of the rim of the tray, as compared with a construction in which the arms are on the inside, for the reason that when the arms are on the outside, the action of the weight on the tray is to drawthe arms inwardly at their lower end. In other words, the action of gravity tends to tighten the connection between the arms and the tray bottom. If the arms are on the inside of the rim, the weight on the tray develops a condition in which the lower ends of the arms tend to move inwardly and away from the side of the tray to which they are attached.

If desired, the tray body may be made of other forms than that illustrated in Figure 2. For example; the tray may have forms indicated in Figures 3 and 4. -As illustrated in Figure 3, the tray body Hmay be of elongated, octagonal form with the ends of the bail attached on the ends of the tray. -*In this, case, the arms I8 of the bail are preferably substantially parallel with the inclined edge ll of'the tray body when the bail is folded down "into the planeof the tray body. As illustrated'in Figures 3 and 4, the bails l8 and I9 are each formed of a single piece of strap metal. In this case, in-order to form a handle to accomplish-the purposeof the rolls I6, I form a knob such as the knobs 2G and 2-! at the upper end of 'the bail. This knob is, of course, rigidly attached, and operates as a handle for maintaining the tray body in a horizontal position. If desired,

these knobs 20 and 2| 'can be constructed of a split sleeve having the general formof the sleeve [4. This'gives uniformity in the general design of the 'trayz.

When the bail is in the plane of the tray body, it will be evident that the'tray can very readily be packed in a small space. I d

If desiredfthe tray can be hung on the wall while the bail is in the plane of the body of the itray, to enable the tray body to be used as apicthe ears 4 received in the horizontal socket bebutwhich wouldbe particularly useful in hospit- .als' as a tray to be set up on a bed to enable a patient to'e'at with" ease. InFigure 6 I illustrate such; an embodiment of the" invention. In this view, 22 indicates thebody of the tray. At its four corners itis provided with means for pivotally supporting four legs 23, which operates as supportsfor the tray to support the same in a ,1 set up position. These legs preferably have roundedlower ends 24 to avoid forming sharp corners which might injure the bedspread. Each leg is pivotallyattached to a corner of 'the tray body on a pivotal axis. In the present instance, I prefer to form the tray body with a cast rim 25 having an integral outwardly projecting pin or pintle 26 near each corner, and on this pin the upperend of a corresponding leg is pivotally mounted. The pin' 26 is of suflicient length to project a considerable distance beyond the outer face off the leg 23, and a coil spring 21 on the pin presses the leg 23, yieldingly against the side of "therim, thereby holding it between the inner vertical facesof posts 28 which project outwardly from the side of the rim. These posts, like the pin 26, may be cast integral with therim. The
