SPECIFICATIONfoI-mng part of Letters Patent No. 724,256, dated March 31, 1903.

Application filed June 3, 1902. Serial No. 110,095. (No model.)

To all whom t may concern.-

Beit known that I, WILLIAM E. BROWN, of Los Angeles, in the county of Los -Angeles and State of California, have invented certain new and useful Improvements in .Jar-Closures; 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. I

The object of this invention is to provide a jar or bottle closure so constructed that in forcing the closure home and securing the gasket-ring in proper position not only will the vessel be made air-tight, but the closure or stopper will be securely locked as against accidental displacement by internal pressure.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section and side elevation.l Fig. 2 is a similar view with the stopper forced home. Fig. 3 is a perspective view of the upper portion of the jar with the stopper removed. Fig. 4 is an edge view of the stopper.

On the interior of the jar, bottle, or other vessel 1, near the upper end, is an annular groove 2, of approximately semicircular formation in cross-section. The stopper 3 has on its neck or reduced cylindrical portion two annular grooves 4 and 5, the former being at or very near the lower end of the neck and separated from groove 5 by a space approximately equal to the distance between the upper edge of groove 2 and the top edge of the vessel.

6 is a gasket-ring of suitable material, preferably rubber, and circular in cross-section, so that it will snugly fit within groove 5 of the stopper and groove 2 of the vessel and prevent all leakage. To insert the stopper, the ring being rst positioned on the lower end, thereof, within groove 4 and made to rest on the upper edge of the jar, pressure upon the stopper will force the latter into the jaropening, the ring going with it, but at the same time riding up on the stopper, so that when it reaches the groove 2 it will also be in line, or approximately so, with groove 5, the

stopper being lthus drawn to its seat with a quick snap. The lower groove 4 is not really essential, as any ,provision `for temporarily holding the ring will suflice, sufficient space being provided between such temporary rest for the ring and the groove 5 as to insure the coincidence of the ring and grooves 2 and 5 when the stopper is forced home.

In the inward travel of `the stopper, with the ring compressed between it and the jar, the coil or twist or roll given the ring is not usually uniform, with the result that the anged end of the stopper will not fit snug against the end of the jar. To effect the proper centering of the ring in its seat, it is necessary to give the stopper a slight axial turn,- whereupon the flanged end of the stopper will be drawn tight against the jar at every point.

To avoid all danger of forcing the stopper by working or fermentation of the contents of the jar, it is essential that thestopper be locked. By my invention I contemplate eecting this locking in the turning of the stopper to center the gasket-ringinits seat. From diametrically opposite 'pointsron the stopper project side lugs 7, which in positioning thestopper in the first instance coincide with cut-outs 8 in the jar. After the stopper'is forced inward the axial turning thereof to` seat the ring will place the lugs in Ways 9, extended laterally from the out-outs beneath overhanging portions 9, thereby locking the stopper as against working of the contents. To remove the stopper, it is necessary to first turn it axially to bring lugs 7 in line with cut-outs 8,

' clearing the overhanging portions 93, whereupon by equal outward pressure of the thumbs against diametrically opposite points of the stopper the latter will be quickly forced outward, the ring aiding in this result vonce it is unseated. As the stopper is withdrawn from the jar the ring will bev around its end in groove 4 if the stopper be provided therewith.

The advantages of my invention are apparent. It will be observed that I have provided simple and highly-ecient means for effectively sealing and locking a processing jar-that is, a jar to be used for food products and then subjected to treatment.

IOO

1. A jar or other vessel having an annular" groove near its upper end, a stopper or closure having a corresponding annular groove near its upper end,ea gasket-ring carried vby the stopper and designed to be seated in the grooves `of the jar and stopper when said grooves are brought into coincidence by the inward movement of the stopper, said stopper being turned axially to center the ring in its seat in said grooves, and means for locking said stopper in place, said stopper being so locked by such means when it is so turned axially, as set forth.

2. A jar or other vessel having an annular groove near its upper end, and also having opposite cut-outs, and ways leading from the inner ends of saidgcut-outs, a stopper or closure having a corresponding annular groove near its upper end, a gasket-ring carried by the stopper and designed to be seated in the grooves of the jar and stopper when said Q grooves are brought into coincidence by the inward movement of the stopper, which latter is turned axially to center the ring in its seat in said grooves, lugs projecting laterally from the stopper near the upper end thereof and designed to be passed through said cutouts and It in said ways, when the stopper is turned axially, as set forth.

3. A jar or other vessel having an annular groove near its upper end and also having cut-outs and overhanging portions, a stopper or closure having an annular groove, a gasket carried in such groove of the stopper designed to be seated in the groove of the jar, lugs projecting laterally from the stopper designed to be passed through said cut-outs and iit beneath said overhanging portions, such lugs being extended beneath such portions when the stopper is turned axially to center the ring in the grooves, as set forth. v

In testimony whereof I have signed this specication in the presence of two subscribing witnesses.

WILLIAM E. BROWN.
