CAN.
APPLICATION FILED MN. I9. 1917.

UNIT STA 'Para iCE.
CAN.
`Specification of Letters Patent.
Patented J an. 8, 1918.
Application filed January 18, 1917. Serial No. 142,993.
To all whom it may concern Be it known that I, MARTHA B. PRATT, a citizen of the United States of America, residing at the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Cans, of which the following is a specification.
My invention relates to cans, and the object of my invention is to provide a can adapted to hold milk or other perishable articles, which is so constructed as to maintain its or their temperature for a considerable length of time; together with such other elements and combinations as are hereinafter more particularly set forth.
I accomplish these objects as illustrated in the accompanying drawing, in which:
Figure 1 is an elevation, partly in section, of my invention.
Fig. 2 is a cross section.
Similar letters refer to similar parts throughout the several views.
I am aware that so-called vacuum cans have heretofore been constructed in which there is a space between the can proper and an enveloping casing, with a means for exhausting the air from this space. Cans constructed in this way have to be made of very heavy material in order that the walls adj acent to the space should notcollapse, and in order to prevent air from entering the vacuum space they have to be constructed with great care and at considerable expense.
The inner wall, A, or what I call the wall of the can proper, is at one end curved, its walls brought closer together and provided with a Haring neck, B. The flange, C, on the cover, D, enters the opening in the top of the can, and the flaring neck is covered by the curved downwardly projecting flange, E, on the cover, iD. On the cover I have provided the space, d, formed by the plate, e, extending across the cover, slightly spaced from the top thereof.
Around the exterior of the wall, A, I place a series of bands or ridges, a, separated from each other and projecting'from the wall as shown in the figures. v
Around the wall, A, separated therefrom, but engaging the ridges or projections, a, is a casing, F, which may be soldered or otherwise secured to the wall, A, at or near its intersection with the neck, B, as shown in Fig. 1. At the lower or opposite end from the neck, the casing, F, may be secured to the flange, b, extending downwardly from the bottom, G, by means of a bolt or rivet, I-I, which passes through the casing, F, and through an angle bar, J, through the flange, b, and the reinforcing ring, K, as shown in Fig. l, or in any suitable manner.
On the bottom, G, of the can and spaced therefrom is placed the false bottom, L, which is provided with a flange, M, which rests upon the bottom, G, and against the side wall, A, of the can. Beneath the bottom, G, through the casing, F, I preferably place the openings, g. The angle bar, J, acts as a support for the lower portion of the wall, A, engaging the exterior of said wall and interior of the casing, F, and held by means of the bolts, H, as already described.
It will be noticed that the continuity of the space between the wall, A, and the casing, F, is interrupted by the ridges, a, extending around the wall, A, and there is thus a prevention of the circulation of air from the bottom to the top of said space. When air is heated its tendency is to rise; if it is prevented from rising the circulation of the heated air is impossible. The result is that the air will not heat so rapidly, will not convey its heat and acts simply as dead air. In the space between the false bottom, L, and the' bottom, G, there is no particular tendency of the circulation of the air. The same may be said of the space, (l, in the cover, D.
I do not limit myself to the number of projecting ridges, c, nor to the material or shape of my can, and by the use of the word can I wish to be understood as including any package or container.
I have shown an annular projecting portion, N, which, of course, may be omitted or changed as desired.
I do not limit myself to the arrangement of the flange, M, on the false bottom, L, which is shown and described as resting upon the bottom, G, as it may be arranged differently without departing from the spirit of my invention.
Vhen I refer to an angle bar, I do not wish to limit myself to one of any particular length or size, nor is it necessary that it should be fastened by means of a bolt or bolts.
What I claim as my invention and desire to secure by Letters Patent is:
A can comprising a receptacle; a series of annular projecting ridges connected therewith; a bottom provided with a downwardly projecting flange; an enveloping casing engaglng sald projectlons; an angle 'bar engaging with the wall of the receptacle ,0 tom placed in the receptacle; a cover provided for the receptacle; and a plate extendng'across the cover forming a space between the top of the cover and said plate, substantially as described.
In testimony whereof I have affixed my 15 signature in the presence of two witnesses. MARTHA B. PRATT. Witnesses:
G. LE Roy BUTLER, ARTHUR E. PRATT.
