VACUUM JAR-CLOSURE.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed April 22, 1909. Serial No. 431,445.

To all whom it may concern:

Be it known that I, VVILLIS J. Pnnnnn, of Summitville, county of Madison, and State of Indiana, have invented a certain new and useful VacuumJar-Closure; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

The object of this invention is to provide an improvedineans for vacuum sealing fruit jars and like jars and bottles, that is simple 1n character, easy to manipulate and economlcal.

The chief feature of the invention consists in providing a jar or bottle with a cap having an inclined gasket and the jar or bottle having an inclined gasket seat, so that the cap can wedge down tightly in place under the influence of external air pressure after partial exhaustion of the air from the interior of the jar; and in the second place, in providing a suction cap flexibly connected with some air exhausting means that is adapted to be readily placed -or laid upon the mouth or neck of the jar or bottle for exhausting the air from the jar or bottle. There is also suctionineans movably associated with said suction cap and forming a part thereof that engages and supports the cap while the air is being exhausted from the bottle and permits the seating of the cap be fore the suction head is removed from the jar or bottle.

With this arrangement jars and bottles can be sealed almost as rapidly as the suction head can be placed upon and removed therefrom.

The full 'nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Figure 1 is a central vertical section through a jar, cap, suction head and associated parts, showing the same while the air is being exhausted from the jar. Fig. 2 is a similar section of the upper part of the jar, cap and suction head with the cap seated justprior to the removal of the suction head.

There is shown in the drawings a jar 10 having a flaring mouth so as to provide an inclined or flaring seat '12 for the gasket 13 of the cap 14. The surface of the cap 14, on which the gasket fits, is tapering, the

object being to so form said cap and the seat therefor in the mouth of the bottle that the cap will, when seated, wedge in place tightly under the influence of external air pressure.

During the manipulation of the device it is desirable that thegasket be placed on'the cap and remain there so as not to fall off. In order to prevent the gasket from falling off the cap during such manipulation, the cap is provided with an extension 15 at its lower end of the same external diameter as the lower inclined portion of the cap on which the gasket fits. The cap can be readily molded of glass when provided with this sort'of extension, and such extension will successfully hold the gasket on the cap.

The air is exhaustedfrom the bottle or jar by the following means: hollow main suction head 20 is provided with a central opening in the underside, and the lower surface having secured to it a rubber gasket 21 or like material and arranged to fit upon the top of the mouth of the bottle or ar, so that when air is being exhausted from said suction head there will be substantially an air tight fit with the mouth of the jar or some portion of the upper part of the jar, so that no appreciable quantity of air from the outside can enter the suction head. Since the suction head is hollow, it does not interfere with the cap 14 or its movement within the suction head.

A rigid pipe 22 extends laterally from the suction head so as to form a handle therefor, as well as to provide a connection with the exhaust air tube 23 that runs to some suitable exhaust pump or exhausting means. At the outer end of said pipe 22 there is a valve casing 24 havin a two-way valve 25 and an air inlet 26.. Vhen the valve is in one position it closes the air inlet and opens the communication with the suction tube 23 and when in the other position it closes the suction tube and opens the air inlet.

The to of the suction head is centrally aperture for the pipe 30 extending through it so as to he vertically movable with reference to the suction head. Said tube 30 has on its lower end an inner suction head 31 that is adapted to engage the top of the cap and lift the cap when air is exhausted throu h the tube 30. Said tube 30 is connecte by a tube 32 with the exhaust tube 23, but there is an intermediate valve casing 34 with a two-way valve 35 and an air bottle.
