VACUUJl/LBOTTLE.
To all whom it may concern:
Be it known that we, Ko vRAD KATHER, a
citizen of the United States, residing in San Francisco, in the county of San Francertain new and useful Improvements in.
Vacuum-Bottles, of which the following is a specification.
The object of our invention is to provide or receptacle for holding and keeping liquids or substances cold or hot, in which the inner bottle is securely centered on the'bottom within the outer bottle to prevent the breaking at the sealed neck.
In the accompanying drawing: Figure 1 is a vertical section through the complete bottle embodying our invention; Fig. 2 is a plan View of the bottom piece of the bottle, and Figs. 3 and 4 enlarged sections through the rim of the bottom piece; Fig. 1 shows the complete bottle A, consisting of the in- C, the bottom piece D, and the air space E.
The inner bottle B, is a complete bottle having in the center of the bottom a pintle F. The outer bottle C, has no bottom the bottom having been removed after blowing the same. The lower rim G, is ground even to give the bottle a length equal to the inner bottle including the pintle F. The inner bottle B, and the outer bottle 0, are then sealedv at the neck N, leaving an equal annular air space E, between them. The bot tom piece D, has a groove or shoulder H, at the outer edge of the exact shape of the lower edge of the outer bottle C, and a socket I, for the reception of the pintle F, of
the inner bottle B.
In assembling the pieces, the bottom piece,
with some liquid cement in the groove, is"
placed in the center of an air pump especially constructed for this purpose, the bot- .tle is secured by a screw plug in the top of the air pump exactly over the bottom-piece. After the air has been exhausted in the air pump, the bottle is lowered by means of the screw plug into the groove of the bottom piece, and the complete bottle removed after Specification of Letters Patent. Applicationfiled August 24, 1909. Serial No.

the cement has set. Another way to assemble the two pieces would be, to set the bottle over the bottom piece and after-sealing them together at the rim, to exhaust the air by means of the tube or nipple T, provided in the bottom piece, which tube is sealed after the air is exhausted from the air space.
Although we show in the drawing a cylindrical bottle, it is obvious that the bottle can be made of any other shape.
We are aware that prior to our invention been made in which the inner bottle was centered by means of separators. of difierent materials, but it is very difl'icult to secure them properly and it is still more diflicult to close the outer bottle over the inner bottle to form the bottom and keep an equal air space between the innerand outer-bottle. We overcome all these ob jections by our improved construction of vacuum bottle, as fully described.
What we claim as 1. A vacuum jacketed'bottle consisting of having a downward projection on its bottom, an outer casing fused to the neck of the inner bottle and of such size and shape as to be uniformly spaced from the inner bottle, and a bottom for said casing having a socket for the reception of said peripheral groove in which is secured the lower end of said outer casing, the air in the space between the bottom and casing and the inner bottle being exhausted.
I new and desire to secure by Letters Patent is:
2. In a double walled bottle, an inner bot- Y I tle having a central projection on its bottom, an outer casing and a bottom for-said casing, said casing being sealed to the neck of the inner bottle and of such size and shape as to leave a space between the bottle and casing, and said bottom having a socket for the reception of the projection on the bottom, a peripheral groove in which the lower end of the casing is secured and means whereby the air between the inner bottle and outer casing may be exhausted.
