HEAT-INSULATED CAN.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed July 20, 1910. Serial No. 572,896.

To all whom it may concern:

Be it known that I, LEONARD It. STEEL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and a State of Ohio, have invented new and useful Improvements in Heat-Insulated Cans, of which the'following is a speciiication.

This invention relates to improvements in ice cream refrigerators.

An object of the invention is the provision of an ice cream refrigerator, the cream holding receptacle of which is preferably formed of glass, earthenware or any other analogous substance, and may be easily removed from the refrigerator when desired to clean the same.

With this and other objects in view, which will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size, and minor details of the device may be made within the scope of the appended claims, without departing from the spirit or sacriicing any of the advantages of the invention.

In the accompanying drawings, forming part of the specication;-Figure 1 is a perspective view of an ice cream refrigerator constructed in accordance with my invention. Fig. 2 is a vertical sectional view of the same.

Similar numerals of reference are einployed to designate corresponding parts throughout.

The refrigerator is arranged within a crate, the said crate comprising a lower circular member 5 and an upper circular member G, the said circular members being connected and held in spaced relation by means of a plurality of slats 7, the upper end portions of which are bentupwardly and downwardly to provide hooks 8 which are insertible through transverse slots formed in the upper and lower circular portions. Arranged at diametrically opposite points on the upper circular portion 6 are a pair of plates one of which is shown in Fig. 1 and designated by the numeral 9. These plates are medially provided with horizontally disposed and outwardly turned portions 10, to receive the handles. As

shown in Fig. 1 each of the handles is preferably formed of a single piece of stout steel wire or its equivalent bent into substantially a U-shape the opposite limbs of which are designated by the numerals 11, the free end portions of said limbs being bent atright angles as shown at 12 and insertible into the opposite ends of the bent portion. lith this construction it will be manifest that the handles are free to swing in a vertical plane when the crate is in an upright position. Arranged within the crate and secured thereto is a vacuum walled receptacle comprising an outer casing (L and an inner casing ZJ. The bottom of the outer casing is designated by the numeral 13 and is peripherally provided with a depending flange 14. Arranged on the inner face of the flange 14 is a ring 15, and arranged on the lower end of the outer casing a is a ring 16, the said rings, flange and lower end portion of the outer casing being provided with openings for the reception of rivets 17 which serve to unite the bottom to the casing. The bottom is further secured and sealed by means of solder. The bottom of the inner casing is circular and designated by the numeral 18, the side wall of the said inner casing rising in a plane with the outer edge of the side wall of the outer casing, the upper edges of said side walls being connected by means of a channeled ring 19, which is secured to the side walls of the outer and inner casings by means of rivets 20 and sealed by solder. The space between the side walls and bottoms vof the outer and inner casings has the air eX- hausted therefrom and a lining of non-heatconducting material designated by the numeral 21 is arranged in said space. A drain pipe is designated by the numeral 22 and extends through the space between the outer and inner casings its inner end communieating with the interior of the inner casing and its outer end leading through the lower end portion of the side wall of the outer casing. The outer end of this drain pipe may be sealed by a plug 23, attached to one end of a chain 24, the opposite end of the chain being secured as shown at 25, to the side walls of the outer casing.

The cream can is designated by the numeral 26, and may be of glass, china, or any other analogous substance and corresponds in length approximately to the length of the inner casing b. The upper end of the cream can 26 is reduced to provide a circular neck 27 to receive a cover 28. The cream can is arranged inra metallic cylindrical jacket, the bottom of which is designated by the numeral 29, and the side wall rising from the periphery of said bottom by the numeral 30. The side wall is provided with a plurality of perforations 3l, and adjacent to its upper end a bead 32 is provided to form a ledge for a cover 33 which fits over the upper end of the jacket. The jacket receives the cream can and its cover. The lower end portion of the jacket is provided with a strengthening band 34, which encircles the lower end portion 'of the side wall of the jacket and the lower edge of which forms a bearing surface for the jacket.

lVith this construct-ion it will be manifest when the jacket and can are inserted into the vacuum walls and -ice placed in the space between the jacket and inner surface of the inner casing Z) and the space suitably covered, that by virtue of the vacuum walls the ice will be preserved for an indefinite period, whereby the cream will be kept in a frozen state, so also, by virtue of the vacuum walls when ice is dispensed with and the space bei tween theupper end of the receptacle and upper end of the cream holding can sealed the cream will be prevented from absorbing the heat of the atmosphere and be kept in a frozen state. It will be observed that the device is exceedingly simple in structure and may be readily cleansed when the cream can is emptied and further the water which collects in the inner casing may be drained through the tube 22, by removing the plug 23.

From the foregoing, it is evident that I have provided a device which is comparatively simple in structure and inexpensive in manufacture, embodying few parts and these so arranged that the danger of derangement will be reduced to a minimum.

l. A refrigerator embodying an inner imperforate can and a perforated jacket, the

i said jacket and lcan each being provided withy a removable closure, anda receptacle surrounding the jacket and spaced therefrom embodying inner and outer imperforate casings, the inner casing being provided with Y 5 a bottom which extends beneath the bottom y of the jacket, the outer casing being extended downwardly below the plane of the bottom of the inner casing, a bottom member having a flanged portion secured to the depending portion of the outer casing, and heat insulating material interposed between the walls of the said inner and outer casings.

2. A refrigerator comprising an inner imperforate can anda receptacle comprising spaced inner and outer casings, the inner casing being entirely spaced from the can, the outer casing having its lower portion extended downwardly below the bottom of the inner casing, the inner casing being provided with a bottom portion which extends beneath the bottom of the can, a bottom member spaced from the bottom of the said inner casing and provided with a peripheral flange, a ring embracing the saidfiange, a second ring interposed between the said depending portion of the outer casing and the said first named ring, fastening devices extending through the said depending portion of the outer casing and through the said first and second named rings, and a heat insulating material interposed between the walls of the said inner and outer easings.

3. A refrigerator comprising an inner imperforate can and a receptacle comprising spaced inner and outer casings, the inner casing being entirely spaced from the can, the outer casing having its lower portion extended downwardly below the bottom of the inner casing, the inner casing being provided with a bottom portion which extends beneath the bottom of the can, a bottom member spaced from the bottom of t-he said inner casing and provided with a peripheral iiange, a ring embracing the said flange, a second ring interposed between the said depending portion of the outer casing and the said Iirst named ring, fastening devices extending through the said depending portion of the outer easing and through the said irstand second named rings, heat insulating material interposed between the walls of the said inner and outer casings, and a ring extending over the upper edges of the said inner and outer casings and secured to said casings.

In testimony whereof I afx my signature in presence of two witnesses.
