MEANS FoR CLOSING'AIR-TIGLHT JARS.
SPECIFICATION forming part of Letters Patent No. 723,508, dated March 24, 1903.
Application filed November-l9, 1902. Serial No. 131,978. (No model.)
To all whom it may concern.-
Be it known that I, ALLEN F. WILsN,a citizen of the United States, residing at Clayton, in the county of Gloucester and State of New Jersey, have invented a new and useful Improvement in Closing Air-Tight Jars, of which the following is a specification.
This invention relates to the closing of airtight jars, such as are used for preserving alimentary substances, and hasfor its object greater facility of closing and opening, greater certainty of air-tight closure, and bet ter durability of the jars and covers and packing for repeated use; and to this end it consists-in an improved construction of cover or cap and in combination therewith an improved form of neck for the jars, between which covers and necks I interpose an improved form of packing or gasket.
The construction of my inventionis shown in the accompanying drawings, in which- Figure 1 is a vertical section of a jar neck and cap embodying this invention Fig. 2 is an inverted plan view of a cap. Fig. 3 is a plan view of the neck; Fig. 4, an elevation of the neck. Fig. 5 shows an enlarged section of a part of the gasket and adjacent parts before closing, and Fig. 6 shows a like section of the same parts when closed.
Referring to the drawings, 1 represents the. neck of a jar, having a shoulder 2 where it joins the body as nearly fiat as is consistent with the delivery of the jar from the mold. A short distance above the shoulder 2 is a circumferential head 3, leaving a groove 12 between them, and above the bead a plurality of segmental projections 4. Above the projection 4 is a cylindric neck 5, terminating in a fiat surface 6. The jars as describedmay be formed in a mold, and the surface 6 maybe ground flat in the usual manner.
7 is the cap, of such diameter near the top as to fit easily on the neck 5 and below at the part below of such diameter as to fit closely around the segmental projections 4 and head 3 and at the lower edge is rounded or beaded to a convex cross-section. A gasket 10, of india-rubber, is placed around the neck 1, so as to fit closely to it, filling the groove 12 between the shoulder 2 and bead 3, as shown in Fig. 5.
In the'inside of the cap 7 are found a plurality of helical segments 9 with short intervening spaces 11, through which the projections 4: can pass upon placing the cap in position, so that the lower rounded edge 8 rests on the gasket-10. Upon turning the cap 1 slightly the helical segments 9 engage the projection 4 on the neck 1 and draw the cap downwardly," causing the lower rounded edge 8 to impinge upon the gasket 10, which it compresses radially, as well as downwardly,
and forces it into intimate contact with lever edge 8 of the cap,.the shoulder 2, the neck 1,. and head 3 making anefiectual sealing of the jar, as shown in Figs. 1 and 6'. But very slight exertion is required to close the jar as thus constructed, and this construction by cooling of the heated contents causes the atmosphericpressure to hold the lid tightly on the jar. By turning the cap in a reverse direction the impingement of the rim 8 on the gasket 10 ceases and air enters the jar, and
it is expandedv without any difficulty.
By reason of the form of neck and head and gasket combined with the convex form of the rim 8 the gasket, while effectually closing the vessel, is unimpaired and can be used repeatedly.
Having described my invention, what I claim is A closing device for air-tight vessels consisting of a neck having a circumferential bead and shoulder with an intervening groove,
a gasket in said groove and a plurality of projecting segmentsin the neck above said head in combination with a caphaving a plurality of internally-projecting helical segments adapted to engage in the segments on the neck and a convex lower edge adapted to compress said gasket in the groove as set forth.
