LIQUID-SEALED JAR.

Specification of Letters Patent.

. Patented I 1' cc. 16, 1913.

Application filed October 10, 1912. Serial No. 724,975.

T 0 all whom it may concern:

Be it known that I, lVILLiAM N. Moons, a citizen of the United States, residing at Pollard, in the county of luscanibia and State oi? Alabama, have invented certain new and nselul Improvements in Liquid-Sealed Jars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a closure for jars or similar .rece itacles for preserving and conserving :trnit, milk, wines and various other articles of food, having for its object to provide an improved fluid seal between the jar and its cover or covers.

In preserving some articles of food it is essential. that the jar shall be rendered airtight, protecting the contents thereof from fermentation and contamination.

One object of the invention is to provide convenient means for sealing the contents of the jar against contamination, wlhich sealing means will )ermit of the escape of gases which may be formed within the jar,

and at the same time preclude insects from gaining access to the contents of the jar.

With these ends in view, the invention consists in providing the jar with a peripheral channel, the outer wall of which is on a lower plane than the mouth of the jar, and a plurality of covers, one of which is adapted to be seated within the peripheral channel and contact with a fluid sealing substance within the channel.

Other objects and advantages of the device will. become apparent from the following detailed description of the invention, taken in connection with the drawings.

In the accompanying drawing, I have illustrated one embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a side ehwation oi the jar, Fig. 2 is a vertical sectional view through the jar, and Fig. 3 is an enlarged fragmentary view showing a portion of the central cover positioned within the ij eripheral channel.

The jar may be composed of anv suitable material, such as pottery, glass, and the like. This jar is provided with a mouth (3, preterably of less diameter than the body of the 'ar therebv formin a curved shoulder 01'- tion 7 and an upstanding collar 8. The innor cover 9, having :1 depending flange 10, [its over the mouth of the ar. This inner cover 1) may be of any suitable material, and

thereby producing a peripheral channel 13 adjacent the mouth oi. the jar. This flange 12 is shown as curved outwardly from the side wall, and thence upwardly, until the edge of the flange is substantially concentric with the mouth of the jar. of this flange is on a lower plane than the upper edge oi the collar 8, forming the mouth of the jar, thereby precluding any liquid, which maybe poured into the channel 13, from flowing into the mouth of the Jar. The base oil the channel 13, which is in alinemcnt with the side walls of the jar, is provided with means serving as a seat 14 for an intermediate cover 1 aml in the drawings this seat is shown rounded, as in so Fig. 3. The outer cover it) is adapted to engage, and lit: over, the top of the outer flange l2, and this top '16 may be provided with a peripheral groove l7, or any other suitable means between the cover 16 and the flange 12.

The channel 1 is adapted to receive a suitable fluid for sealing the jar, and this fluid may be drawn oil from the channel,

when it is desired to gain access to the contents of the jar, by opening a port '18, adapted to be closed by any suitable means. In the drawings, I have shown the port closed by a stopper 1.5), but it is obvious that any other means may be employed.

The various covers may be provided with any suitable means, as at 20, for handling the same. l urthermore, the jar 5 may be provided with suitable means tl'or transporting it, such as the handle 2t ears 532.

Should. the cover it, become broken, or accidentally displaced from position, or should the flange 12 become broken sullicient to permit the fluid, or a portion there- 105 oil, to escape from the channel iii, the

covers

9 and 15 will serve to protect the contents of the jar. Even should the outer and i11 termediate covers 16, 15 become displaced from the jar, the inner cover 1) will serve to 11!) close the jar.

In operation, the artlclcs to be stored are The upper edge 70 'l'or producing a tight joint 85 pivoted to the placed within the jar through the mouth 6, the cover 9 is alaced in position over the mouth 6, then t e intermediate cover 15 is positioned over the inner cover 9 until the edge thereof engages the seat 1d of the channel 13. Any suitable fluid may be poured into the channel 13 to seal the jar, care being taken that port 18 is closed. The outer cover 16 may be placed in position to engage the top of flange 12, there'- by protecting the fluid from evaporation, as well as from dust and contamination with injurious substances. In storing fermenting substances within the jar 5, the gas may be permitted to escape from the jar into the chambers between the inner and central covers, or between the central cover and the outer cover.

Having thus what I claim as new and Letters Patent, is:

1. In a device of the class described, a jar provided with a mouth, av flange concentric with tween the flange and mouth, a seat at the base of the channel, a cover adapted to engage the flange, another cover for the mouth of the jar, and an intermediate cover adapted to rest in the channel.

2. In a device of the class described, a jar rovided with a mouth of less diameter than the body of the jar, a flange concentric with described my invention, desire to secure by the mouth producing a channel bethe mouth of the jar, said flange being of greater diameter than the body of the jar, and on a lower alane than said mouth, and a plurality of covers for the jar comprising an inner cover for the mouth of the jar, an intermediate cover adapted to rest on a seat in alinement with the walls of the jar, and an outer cover adapted to engage said flange.

3. In a device of the class described, a jar provided with a mouth of less diameter than the body of the jar, a flange concentric with the mouth of the jar of greater diameter than the body of the jar, said flange forming a channel concentric with the mouth of the jar, a seat at the base of the channel, and a series of covers for said jar, one of said covers being provided with means for engaging the edge of the flange, another 01": said covers adapted to fit over the mouth of the jar, and an intermediate cover adapted to be positioned to rest upon the seat within the channel and in alinement with the side wall of the jar, whereby when fluid is placed within said channel, the intermediate cover will contact with the fluid.

In testimony whereof, I aflix my signature, in presence of two witnesses.
