To all whom it may concern: a a

Be it known that we, CORTLAND W. DAVIS and FRANK R. SUNDERLIN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Insulated Vitreous Receptacles; and we 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 appertains to make and use the same.

Our invention relates to insulated vitreous receptacles, objects thereof. being to render such receptacles immune, as far as possible, from external thermal influences, and also to shield them from blows and shocks which are incident to transportation and use. I

Referring to the drawings I Figure 1 shows a vertical section of'thereceptacle, portions thereof being shown in elevation.

Fig. 2 is a plan view of a cover for the vitreous portion of the receptacle.

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

Fig. 4 is a large detailed section of an upper portion of the receptacle.

1 is a non-vitreous protective jacket, preferably made of sheet metal, rolled and bent into cylindrical form, the edges of the sheet being overlapped, riveted and soldered together in the usual manner;

2 is a vitreous container, between which and the protective jacket is-a space for the reception of a non-heat conducting filling, 3, which is preferably granulated cork,-although it may be composed of any suitable heat insulating material. The exterior surface of the container is-preferably silvered.

Separation of the jacket 1 and container 2 is maintained by braces, 4, 4, the braces? being set diagonally, as shown, to assist in taking the end thrust .of the container. It will be understood that the filling of material is tightly packed in the space between the jacket and the container, so as to prevent relative motions of the parts.

5 is a seat fora brace 4,.secured to the inner wall of the jacket 1' by rivets 5". Screws 5 extending through a hole 5 in the seat 5 and into the brace 4 secure said brace in fixed relation to said jacket. The wall of the jacket 1 is provided with .upper corrugations 6, and lower corrugations 6 which, in a great measure, prevent the filling 3 from moving longitudinally in the annular space between the jacket 1 and the container 2.

The jacket 1 is provided with a bottom 7 having a downwardly extending flange 7 riveted and hermeticall sealed to the lower edge of the jacket 1 wh ch constitutes a support for the receptacle.

A reinforcing ring 8 encircles the lower end of the jacket 1.

9 is an annular yielding shock insulating diaphragm, 4 preferably made of copper, soldered at its upper end to the inner wall of the jacket 1.

a suitable bonding agent and preferably made of any non-corrosive metal, such as brass. .This collar has, an inturned flange v The container 2 is pror' -vided with a collar 10, secured theretoby U 10 which rests onthe top edge of the container 2. This collar 10 is also provided with an outwardly extending sloping flange 10", forming a groove for solder and overlapped by the inner edge of the diaphragm dered together at their overlapping parts.

The shock insulating diaphragm 9 is provided with a cylindrical body portion 9, and an outwardly extending flange 9 having a turned-up edge 9 which extends to edge 9 is to provide a large contact surface for the solder, and to leave a space 9 through which shocks administered from the outside will not be transmitted to the main bod of the diaphragm 9 and to other parts of t e constructlon. It will be observed that 9, the diaphragm and the collar belng sol- 4 the top of the jacket 1. The objects of the the general shape of'the diaphragm 9 is such 4 as to rovide a depression 9 which extends entire y around the neck of the vitreous container to prevent externally administered shocks from reaching said neck. The use of copper in the construction of the diaphragm 9 adds further security to the Vlt',

reous container, it having been found that soft metal, such as copper, will yield without transmitting shocks. Copper is, furthermore, useful in this relation inasmuch as it i is only slightly corrodible and is easy to kee lphclean.

e device is" rovided with a bail 11, the

inturned ends which oscillate in holes 12 in the body of the jacket 1, said inturned ends being provided inside said jacket Wltlt perforations 11, through which extend cotter pins 11 Cups 13 soldered to the inner wall of the jacket 1 inclose the inwardly protruding ends of the bail.

The container 2 is provided with a'cover i 14, consisting in the main of a circular body of cork 14 adapted to fit within and tightly close the neck of the container 2. 14 is a protective cap covering the entire upper surface of the cover '14: and extending downward around the margin of said cover to form a fiange 14. The cap is secured in position on the cover by bolts 15 having nuts 15 resting in depressions 14 of the cover, these depressions being filled with cork plugs 16. While we prefer cork as the ma.- terial for the cover, it will be understood J that other substances which are poor conductors of heat may be used instead of cork.

The fiange 14 may be of such size as to constitute a shoulder for the cover 14, whereby said cover may bear upon the top edge of the neck of the container, or upon the inwardly turned flange 10 of the collar 10.

The cover 1 1 is provided with a swiveled cross bar 17 having downwardly turned ends 17 which are provided with inwardly extending tapering lugs 17 which may be formed by bending inward a portion of the metal.

The collar 10 is provided with a series of outstanding rivets 10 extending through and riveted inside said collar. These rivets are positioned to engage the tapered lugs 17 of the cross bar 17. to thereby lock the cover it in position on the container 2. The cross bar 17 is swiveled on one of the bolts 15 which carries on a screw threaded portion thereof a nut 15 spaced sufiiclently far from the head of the bolt to allow the cross bar to during its oscillations.

turn freely on said bolt as a pivot. The cap 14* has a raised center 14 which prevents of the collar and the annulus 10 and 9 will be melted, so as to free the container and allow it to be withdrawn through the open bottom ofthe jacket 1 and anew container inserted in lieu thereof.

The jacket 1 is encircled by a protecting ring 8 secured thereto by rivets.

The entirereceptacle is closed by a cover 18 having a flange 18" fittin snu ly over the reinforcing ring 8*. The e geo? this flange 18 is provided with a bead 18 with which a pivoted clamp 19 is adapted to engage, this clamp 19 being provided with a groove' 19 adapted to,fit said head 18". The pivot of the-clamp 19 is formed by rivets 20'fixed in the jacket 1 and loosel fitting openings 19 in thelower end' of tl ieclamp'. A headed bolt 21 fixedly secured inthe reinforcing ring 8, threadedat its outer end and extending through an aperture 19, is engaged by a I thumb nut 22, by means of which said clamp 19 may be forced into engagement with the bead 18 The thumb nut has a depression 19 in which the head of the retaining bolt 21 moves. Several of these clamps 19'may be employed, as desired.
