This invention relatesvto .a method for sub- I iecting succefive containers un1nterrupted y to succesively' increased vacuumization,
and has for its object amode of procedure I whereby containers and their contents are moved into .gradually increased vacuum1z-' ing influence and whereby it is possible to apply a high degr gradually increasing de ees. to thus enable y products to be vacuumized, pre erablyrin their containers,

It is found,

The cans may be moved into position bythe star wheel 13, to travelalong a track 14 and into 1 pock ts" 15 .of the pressure seated valve 10.

of external and internal pressure. In order] to facilitate this feature and the assembly of the valve, I Preier to construct the'valy 1n the shape-o, an inverted truncated which fits into its jacket 18. jacket is sup filied with a number of ports '1 20311181 21 w ch 'are'located .at proper in-fv and are'inldir'e'ct connection'withtha v;

through the vacuum chamber wall 30.
From the illustrative device as herein disclosed, the mode (if operation which embodies my invention is readily apparent to those versed in the art. By proper adjustment of valves 27, 28 and 29, varying degrees of vacuumization are-maintained in the regions of port openings. By thismeans I maintain a successively higher vacuumization as the can travels towards the vacuumizing chamber, thus, as a specific example, if
the gauge reading for port 19 is, say, 10 for certain materials, I so adjust the successive valves as to give a successively higher vacuumization for each po'rt provided. The adjustments are so made that there will be no abrupt change of pressure as the containers ass any one port, or into the chamber itse f, and the material in the container will not be caused to spill or to fly about. My method of gradation of vacuumization may obviously be applied to liquids, as condensed milk, as 'well as to owdery materials, such as milk powders, baklng powders, cocoa Having now described my invention and given a specific embodiment thereof, what I claim as new and useful, of my own invention, and desire to secure by Letters Patent is:
1. The method of submitting materials in containers to successively increased stages of vacuumization, which comprises causing containers to move through successively higher vacuumization areas'and maintaining in said successive areas controlled gradations of vacuumization of a degree. as will caulse no disruption of the materials vacuum- 2. The method of submitting materials to successive stages of vacuumization which comprises causing said materials to be subjected to successive higher stages of vacuumization and causing said vacuumization to be controlled at said stages. r
3. The method of submitting materials in containers to successive stages'of vacuumization, 'which comprises causing said containers to move into areas for maintaining said stages of vacuumization and causing gradations of vacuumization to be maintained in said areas under positive control,
I said gradations of vacuumization being maintained to a degree insuflicient to cause disruptive efi'ects upon said materials as vacuumization.
4. The method of submitting m terials in uniformly moving containers to fierent degrees of vacuumization, which comprises causin said containers being moved into successlve areas of vacuumization and causing the degree of vacuumization-of each suc cessive area to be controllably maintained by gradations insufiicient to cause disruptive agitations in the materials as the containers move from one area to the other.
5. An apparatus for vacuumizin materials without causing said materia s to be agitated by variations in degrees of vacvacuumization areas, a port for admitting a stream of containers into a vacuumizing chamber while maintaining a uniform degree of vacuumization therein, a valve for said port, said valve being seated b atmospheric pressure, and said port wa ls bein provided with a plurality of openings, an a conduit pipe connecting the vacuumizing chamber and said port through a' plurality of port wall openings whereb the materials passing said openings are su jected to vacuumizing influences of varying de ee.
7. In an apparatus for subjecting materials in containers to successively increased vacuumization areas, a port for, admitting a stream of containers into a-vacuumizing chamber while maintaining a uniform degree of vacuumization therein, a valve for said port, said valve bein seated b atmos-' pheric pressure, and sai port wa s being,
through which said containers are caused to adually increased vacuumization move 'uninterruptedly, a pressure seated 4 valve for conveying said-containers through said port, and means in said port for subjecting said containers to gradually increased vacuumization. they are moved mto said successive stages of 9. A vacuumizing apparatus for subjecting materials in moving containers to gradations of gradually increased vacuumization for preventingdisruption in the mass of said materials when admitted into the vacuumining chamber, a port for pressure seated truncated said port, pockets in said 5 in containers into taming a: constant degree said chamber, a conical valve in valve for carrysaid chamber while mainof 'vacuuinization therein, and means associated with said port for causing va ing degrees of vacuumiza-' tion to be estab ishedin said pockets while conveying containers into said chamber.
