TRAY.

Application filed October 15, 15H9.

T0 all whom it may concern:

Be it known that I, LoUis MYERS, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Trays, of which the following is a specication, reference being had therein to the accompanying drawings.

rllhe invention relates to trays such as are used for the carrying of dishes in restaurants and similar places, and it is the object of the invention; lirst,to obtain a construction which will to a large extent deaden the sound; second, one which provides heat insulation for the bottom of the tray; third, a construction which can be cheaply manufactured and` which is both strong and durable.

In the drawings:

Figure l is a perspective view of a series of trays in nested relation;

Fig. 2 is a vertical cross-section through a pair of nested trays;

Fig. 3 is a similar view showing a modified construction;

Fig. a is a plan view of the outer member of the tray.

il is a pressed sheet metal member, pr'.s erably formed of steel, and being providf with a corrugated bottom portion B aint upturned marginal iiange C having a bead D at its upper edge.- E is a second sheet metal member, preferably formed of alumi-n i.. num and which has a flat bottom portion t spaced from the corrugated bottom B, .a marginal flange G fitting within the marginal flange C and extending around the bead D, as indicated at H. Between the bottom F of the member E and the bottom B of the member A is interposed a sheet of asbestes I or other material. having heat insulating and sound d eadening properties.

With the construction as described the proportion of parts is such that the, trays will nest with each other, the thickness of the composite bottom B, I, F being preferably slightly greater than the diameter of the bead. Thus when the trays are nested with each other, the bottom B of the upper tray will contact with the lining F of the lower tray and on account of the asbestos or sound deadening material, very little vibration will be transmitted. The same is true when dishes, or other articles, are placed within the trays as the aluminum Specification of Letters Patent.

lining is thin and iiexible and therefore will produce little sound by impact, while the asbestos beneath forms a cushion absorbing the shock.

rin additional feature of advantage is the heat insulating character of the bottom so that where hot dishes are placed on the tray the heat will not be conducted therefrom with sufiicient rapidity to injure the table or lother support on which the tray is placed. Still another advantage is that the cost is lessened by the use of a thin aluminum sheet, while all the requisite strength is imparted to the tray through the pressed steel member. Moreover, the aluminum Vcon'ipletely protects the steel on its inner face and around the bead, while the other face may be japanned, galvanized or otherwise provided with a protecting coating. The construction is therefore one which is very useful and can be manufactured at relatively low cost.

In the modified construction shown in Fig. 3, instead of placing the heat insulating material I between the inner and outer members of the tray, the inner member rests upon the top of the corrugations of the outer member. rlhis will still give a cushioning eEect and a degree of heat-insulation, inasmuch as the contact between the two members is very limited.

Vhile I have described the tray as being formed from sheet metal, it is obvious that other materials might be used.

wWhat I claim as my invention is:

l. A tray, comprising a sheet metal member having a bottom and an upwardly-extending marginal flange, a second sheet metal member provided with a bottom and marginal flange, the flanges of the two members fitting against each other and the bottoms being spaced from each other, and a filler of cushioning heat-insulating material between the two bottoms.

2. A tray, comprising a pressed sheet metal member having a bottom and an upwardly-extending marginal iiange extending thereabout, said flange terminating in a bead, a second pressed sheet metal member forming a lining for the first-mentioned member and also provided with a bottom and marginal flange, said flange fitting against the flange of the first-mentioned member and extending around the bead thereof, the bottoms of the two members being spaced from each other, and a filler or' cushioning heatinsulating material between said bottoms.

A tray, comprising a pressed sheet metal member having a corrugated bottom and an upturned marginal iiange extending thereabout, said flange terminating in a bead at its upper edge, a second pressed sheet metal" member having a plane bottom spaced vfrom said corrugated bottom, and

a marginal flange fitting against the mar-v ginal langelotthe first-mentioned memberVv and vextending around the bead thereof,

and a liller of cushioning heat-insulating material resting upon the corrugated bottom of the lower member bearing in the plane bottom of the upper member.

,4e A tray, comprising a cooperating pair of pressed sheet Vmetal members, each hav-F ing a bottom and an upturned marginal Vflange extending thereabout, terminating in abead at its upper edge,one of said membersbeing formed of pressed steel and having the bottointhereoil corrugated, and

the other otsaid members being formed of Valuminum and having a plane bottom, the

flange of the aluminum member fitting against and extending ai'ound'the corruga-V tion of the ange of the steel member and the plane bottom being spaced from the corrugated bottom, and a liller of cushioning heat-insulating material such as asbestos being Yarranged between the bottoms.`

5. A tray, comprising a pair of coperating pressed sheet metal members, the'lower member having a corrugated bottom and an i images upturned marginal flange extendingthereabouttermniating in a bead at its upper edge and the upper member having a plane bottom spacedv'rom the bottom of the lower member, a marginal flange fitting against the marginal flange of the lower member VandV extending around the bead thereof, and arller of cushioning heat-insulating Vmaterial such Vas asbestos between the bot-V spacedvand for permitting the weight ofthe superposed tray resting on the bottom of the lower tray. y

7. The combination with a pair of nested trays Yeach comprising a member having a bottom and an upwardly-extending marginal Harige terminating in a bead at its upper edge and means for reinforcing said bottom,

said reinforcing means having la thickness slightly in excess oi" the diameter of `said bead, whereby engagement of the beadro one tray with that of the other tray is prevented. i Y

In testimony whereof I aiiix myzsignature.

LOUIS MYERS.
