WILLIAM H. BAUGHMAN', OF BAY CITY, MICHIGAN.

BECEPTACLE.

I Specification of Letters Patent.

Patented July 16, 1918.

Application filed June 19, 1915. Serial No. 35,024.

To all whom it may concern: I Be it known that I, \VILLIAM H. BAUGH- MAN, a citizen of the United States of America, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Receptacles; and I do hereby declare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it upper-rains to make and use the same.

This invention relates to a construction of receptacles of especial use in connection with receptacles to contain liquids or articles of food at a temperature above that of the surrounding atmosphere. It is the object and purpose of this invention to provide a con struction which is practically proof against loss of heat through the outer walls thereof. Various other objects and purposes consisting of novel constructions and arrangements of parts will be apparent as understanding is had of the following description, reference being had to the accompanying drawings, in which: i

Figure 1 is a side elevation of a receptacle embodying my invention.

Fig. 2 is a. vertical section on the line 2-2 of Fig. 3.

Fig. 3 is a plan view with a part of the receptacle top broken away.

Fig. l is a transverse section taken through the receptacle top, the intermediate plate being removed.

Fig. 5 is a fragmentary side elevation of the reinforcing plate located between the walls of the receptacle and the top thereof; and

Fig. 6 is a. section on the line 6--6 of Fig. 5.

Like reference characters refer to like parts throughout the several views of the drawing.

In the construction shown an open topped receptacle member 1 is provided having a base 1". Within, this member a smaller member 2 having a similar base 2 is positioned the walls of said members and the bases thereof being spaced a distance apart. At their upper edgesthe receptacles are connected by an annular section 3 which may be secured thereto in any suitable mannor. a space is provided which is entirely inclosed by said members; and it is designed that the air shall be exhausted from this Between members 1, 2, 1", 2 and 3,

space, it being then sealed against any further entrance of air. Ears l secured to the outer member 1 at diametrically opposed points carry a bail 5 equipped with the usual handle 6 whereby the device as a whole may be readily carried. To reinforcethe side walls of members .l and Q a plate 7 interposed therebetwcen and similarly a plate 8 is interposed between the bases 1 and 2. These plates have struck therefrom at a plurality of points triangular tabs 9 which, extending in both directions, hear at their pointed ends against members 1. 2, l and 9" as will be readily understood from reference to Fig. 3. Plates 7 and 8 are located between the said members previous to their connection together and before the air has been exhausted from the space inclosed thereby. It will be apparent that the outwardly extending tabs 9 serve to resist the tendency to collapse of the members under the air pressure when. the air has been exhausted from the said space. Also the pointed ends of tabs 9 resting a ainst members 1, 2, 1 and 2 furnish no appreciable conta ct surface for the conduction of heat to the outer member 1 from the inner space surrounded by member 2 and thence to the outside atmosphere; while on account of the vacuum produced between said members there will be no passage of the heat through air contact between said members.

The top to the receptacle is formed in a similar manner, consisting of upper and lower plates 10 and 11 spaced apart with the space between them inclosed by an outer ring 12. A plate 13 provided with triangular tabs 14 similar to the tabs 9 is interposed between the said plates and the air exhaustcd from the space inclosed by them. This cover is applied to the open topped receptacle, it having on its under side 11 an annular flange l1 which fits tightly within the member 2 as shown in Fig. '2.

A receptacle adapted to contain liquid is shown at 15 secured to the underside of the top. The contents of the receptacle may be withdrawn through the passage 16 formed in the top and which may be normally closed by a cork 17. its usual in constru ...ions of similar nature, a cup 18 is detachably connected over an annular ring 19 projecting upwardly from the upper side 10 of the cover. A. receptacle of this construction may have liquid or articles of food introduced therein while at a temperature far above normal atmospheric conditions, the liquid being retained in the part 15 and articles of food of solid nature below said part. By reason of the construction outlined, heat cannot escape through the walls or the top. of the receptacle but will be retained for a long time.

The construction described is very cheaply and economically produced at a comparatiyely low cost. Various modifications in minor detail may be resorted to without departing from the invention which is defined in the appended claim and all modifications in structure falling within the scope of said claim are to be considered as comprehended within my invention.

I claim In combination, a receptacle, a cover for the receptacle including upper and lower plates spaced apart, a ring inclosing the space between the plates at their edges, a flange pro1ect1ng from the lower plate adapted to be inserted into and bear against the inner side of the receptacle, heat passage prevention. means interposed between the upper and lower plates, a receptacle depending from the lower plate inside the flange, an outlet thereto extending through both plates, a closure for the outlet, and an up- -wardly pro ecting flange surrounding said Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
