FRUIT rnnsnavna.

Application filed February 5, 1925. Serial No. 6,950.

To @ZZ zc/10m t may concern.'

Be it known that I, liViLLIAM DON, a citi-r en of Germany, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful mprovements in Fruit reservers, of which the following is a specilication.

This invention relates to jars used in preserving fruits, vegetables and the like by means of creating a vacuum and has as one of its objects to provide a jar having a hei1` metically closing cover and means for eX- hausting the air from within.

Another purpose is to produce an eilicient hand pump provided with a gaugepto indicate the extent of the vacuum attained.

` A further aim is in the provision of means to prevent an inflow of air upon the removal 0 of the suction pump.

These several objects and others of like character, which include simplicity, ease of operation and low oost of construction, are attained by the novel design, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a front elevational view showing`a complete embodiment of the apparatus', partially in section to disclose the con'- struction.

Figure 2 is an enlarged fragmentary sectional view of the air extracting connections, looking on line .Q -9 of Fig. 3.

Figure 3 is a fragmentary top plan view of the jar andits air exhausting connection.

liigure d is a transverse sectional view taken on line 4-fl of Figure 2.

Referring more in detail to the drawing, the numeral designates in general a cylindrical jar or crock having an imperforate bottom and an outstanding annular flange 11 adjacent its open upper edge.

Seat-ed on the iange 11 is a packing ring 12 and normally disposed on the ring is a wide faced band 13 formed on the cover 14 which is guided by the extending edge of the jar as clearly shown.

Fixed centrally in the ring 12 is the flattened portion 15 of a thin metal suction head, lshaped to present a plurality of oriices 16 open at the end extending through the ring 12 and communicating with the The tube 18 is connected at its opposite i end with the suction inlet 21 of a manually operated suction pump having a cylinder 22 and operating handle 23, vthe inlet being provided with a vacuum indicator 241.

In'operation, the articles to be preserved, such as whole apples or fruits and the like, in a sound condition, uncooked and free of sugar or other substances, are placed in the jar, the cover applied over the ring and the tube 18 connected to the suction head.

Thereafter the pump may be vigorously operated, exhausting the air to the point of forming a partial vacuum and creating a suction on the cover snilicient to hold it tightly in place.

The morenearly perfect the vacuum is, the better the articles will keep and if no air be permitted to enter, the fruit can be maintained in good condition indefinitely.

When the air has been exhausted so far as is possible by the pump, the tube is removed from the suction head, sucking the sphere to its seat and maintaining'in operetive position until displaced by hand at such time as the articles are required.

Although the foregoing is generally descriptive of the preferred embodiment of the invention, it is to be understood that minor changes may be made within the scope ol" the appended claims.

Having thus: described my invention, what l claim as new and desire to ters Patent, is y 1. A packing ring comprising a thin flat annulus composed of flexible material, and of uniform thickness, a head having a plurality of flattened tubular elements extending radially through said annulus, said tubes eing open at their inner endsand merging into a cylinder at their outer ends,lmoans for exhausting air from said head, and a rubber sphere freely movable in said cylinder to prevent air from entering said tubes. 2. A packing ring comprising a thin Hat secure by Let-- annulus composed of flexible material, and of uniform thickness, a head having a plu; rality of flattened tubular elements extending' radially through said annnlus, said tubes being` open at their inner ends and merging into a cylinder at their Outer ends, a flexible tube engageable Withsaid cylinder7 said tube engaging` with a suction means, a ball valve in said cylinder to close the openings to said flattened tubular elements, and 10 means te retain said valve in the cylinder.

In Witness whereof I have aflixed my signature. v
