JOHN MARION STUKES, OF SAN ANTONIO, TEXAS, ASSIGNOR OF ONE- HALF TO BARTON GEORGE LANE, OF BEXAR, TEXAS.

VACUUM STORAGE AND PRESERVING CAN.

Specification of Letters Patent.

Patented Aug. 1, 19L 5.

Application filed January 27, 1905. Serial No. 242,914.

T 0 all whom, it Duty concern.-

Be it known that 1, JOHN MARION STUKEs, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Vacuum Storage and Preserving Cans or Receptacles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a receptacle or can for the storage and preservation of eggs and also other perishable food products and articles that would be damaged by atmospheric influences, said receptacle or can having means for creating a vacuum therein to assist in the preservation of the contents; and it consists in a vacuum can or receptacle constructed substantially as shown in the drawing and hereinafter described and claimed.

In the accompanying drawing, which represents a sectional elevation of my vacuum storage and preserving can or receptacle, A designates the body thereof, and B O the conical heads, said can or receptacle being of any desirable size and shape and of metal or other suitable material found best adapted to the purpose. The heads B O are formed convex, so as to guard against the heads collapsing or buckling when a vacuum is being formed therein, the convex form of the heads giving greater strength thereto to overcome the outer pressure of the atmosphere when the vacuum is completed. The heads B C are secured to the body A some distance from the outer edge thereof, as indicated at a, so that the heads will be more rigid and their strength reinforced, which is considered essential in view of the fact that the outer pressure of the atmosphere is removed from the interior of the can or receptacle.

The can or receptacle as above described has a central opening 6 in the head B, which is surrounded by a screw-neck c, suitably secured to the head, and engaging with this screw-neck is a removable cap D, and when said cap is removed access may be had to the interior of the can or receptacle. The screwcap C has a suitable eye d secured to its under side, and to this eye engages a book 0, which hook also engages the bail f of a pail or vessel E, thus suspending said pail or vessel from the under side of the screw-cap and also admitting of the pail or vessel being removed when desired. The object of the pail or vessel E is to contain chlorid of lime when it is necessary to secure a perfect dry condition inside of the can or receptacle or to place water in the same when more moisture is required, as found desirable.

In the head B is an opening g, and to the head and around this opening is an exterior screw-thread tubular nipple F, having an interior valve-seat h, to which is secured the valve 2', thus providing an automatic checkvalve and means for securing the end of a rubber or other tube to the nipple, which connects with any suitable means for sucking or drawing the air out of the interior of the can or vessel to form the vacuum, the check-valve automatically closing when the tube is removed from the nipple by the pressure of the outer atmosphere thereon, and thus preventing the air from passing into the can or receptacle after the vacuum has been created.

Connecting with the head B is a tube j, which communicates with the interior of the can or receptacle, and connecting with the tube is a suitable gage G, which ascertains the degree of vacuum being formed in the interior of the can or receptacle.

It is evident that the article or articles placed within the can or receptacle, such as eggs, will be preserved in their natural raw state and all perishable food products, as well as garden-seed, tobacco, all classes of chemicals and drugs, and, in fact, anything that requires preservation through the medium of the vacuum process.

Having nowfully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A vacuum storage and preserving can or receptacle, a gage communicating with the interior thereof, a check-valve device also communicating with the interior of said can or receptacle and having means for connecting a pipe or tube thereto, one of the heads of the can or receptacle having an opening therethrough, a removable screw-cap to close said opening, and a pail depending from the under side of the screw-cap and removable therefrom, substantially as and for the purpose specified.

2. Avacuum storage and preserving can or receptacle having convex heads secured to the body some distance from the outer edges thereof, one of said heads having an opening through which access to the can or receptacle may be obtained and an air-tight cap to close the opening, a gage, and a check-valve device communicating with the interior of the can or receptacle and provided with means i for securing a pipe or tube thereto, and a pail or vessel depending from the interior of the JOHN MARION STUKES.
