FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 282,916, dated August 7, 1883.

Application filed January 3, 1883. (No model.)

To all whom, it may concern.-

Be it known that I, JosEPH MURPHIN, a citizen of the United States, and a resident of Malaga, Gloucester county, New Jersey, have 5 invented certain Improvements in FruitJars,

of which the following is a specification.

My invention relates to a certain improve ment in the fruit-jar for which Letters Patent of the United States No. 255,005 were granted to my assignees 011 the 14th day of March, 1882, the object of my present improvement being to provide for the admission of air to the in terior of the jar, so as to permit the removal of the cap.

In the accompanying drawings, Figure l is a perspective view of the top of a fruit-jar with my improvement; Fig. 2, a sectional view, showing the jar closed; and Fig. 3, a view showing how the admission of air to the jaris effected. f

The patented fruit-jar above alluded-to was. sealed by means of a rubber ring, 00, clamped between a bearing, a, 011 the jar and a bearing, b, on the inside of the cap, the ring as being first deposited horizontally on a contracted shoulder, (1, around the mouth of the jar, and being then turned to the vertical position and clamped between the bearings a and b as the cap was pressed down, a shoulder in the cap bearing upon the outer projecting portion of the ring, to facilitate the proper turning of the same. Some difficulty has been experienced in removing the covers so applied, owing to the absence of any means of permitting the 3 5 entrance of air to the interior of the jar, so as to destroy the partial vacuum therein. This objection I overcome by forming in the outside of each jar a groove or recess, 3 which extends up into the bearingsurface a, but not to the top of the same. The bearing of the 40 ring it on the surface a is thus reduced at this point, as sho wn in Fig. 2, so that when a pointed instrument is introduced'into the recess and behind the ring as in Fig. 3, alimited portion only of said ring has to be displaced in order 5 to permit the entrance of air to the jar, whereas if the ring xhad its full bearing on the surface a some difficulty might be experienced in so displacing said ring as to permit the entrance of air.

' I claim as my invention 1. A jar having a vertical annular bearingsurface, a, below the mouth, and having an exterior groove or recess, 1, the upper end of which extends up into said bearing-surface a, 5 5

as set forth..- g
