TAR-CLOSURE.

Specification of Letters Patent;

Patented Nov. 11, 1919.

To all whom it may concern Be it known that I, HERBERT ZIERLEIN, a citizen of the United States, residing at LomaX, in the county of Custer and State of Nebraska, have invented new and useful Improvements in Jar-Closures, of which the following is a specification.

My present invention has to do with jar closures; and it consists in the simple, compact, reliable and easily effected closure, hereinafter described and definitely claimed.

In the accompanying drawings, which are hereby made a part hereof:

Figure 1 is a diametrical section illustrative of my novel jar closure.

Fig. 2 is a side elevation of the same.

Fig. 3 is a top plan view, and

Fig. 4: is a detail view, illustrative of the closure bail and the cam lever carried thereby.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

My novel closure is designed more especially for use in conjunction with a strong shouldered jar of the general construction illustrated; the said jar being provided with a neck 1, characterized by a circumferential groove 2, which latter may be of spiral type or any other type compatible with the successful use of my invention.

My novel closure comprises a cap 3, preferably of glass, concave at its upper side, provided in its under side with a circular groove 4, in which groove is seated a yield ing washer or gasket 5, designed to be opposed to the upper edge of the neck 1.

The closure also comprises a wire bail 6, possessed of more or less resiliency, and a cam lever 7 which is preferably, though not necessarily, formed of cast iron. The bail 6 is shaped in approved manner into the con figuration illustrated, so that it comprises a transverse crown bar 8, arms 9 depending from the ends thereof, and curvilinear. terminals 10, which reach laterally from the lower ends of the arms 9. As best shown in Fig. 1, the said terminals are of peculiar construction with a view to lending increased stiffness and strength thereto, the peculiarity consisting in bending the terminals in curved manner from the ends of the arms 9, and then bending the end portions of the wire back upon the terminals, so that each terminal 10 is made up of a loop having an outer portion 11, a bight 12, and an inner portion 13, the inner portion being of increased length and extended rearwardly of thearms 9 about the proportional distance illustrated. By virtue of this peculiar formation, the terminals 10 are possessed of great stiffness and strength, and at the same time the comparatively long inner portions 13 are calculated to effect a long and strong engagement of the bail with the grooved neck of the jar.

The cam lever 7 is pivotally mounted, preferably in loose manner upon the bail, the loose arrangement being preferable inasmuch as it permits of said cam lever be ing shifted laterally as desired on the crown bar 8, which serves as its fulcrum. The cam lever is characterized by a head 15 and an arm 16, on which is a stop protuberance'17 and a finger-piece 18; said fingerpiece constituting the terminal of the lever and being arranged in rear of the stop protuberance to enable an operator to conveniently take hold of the lever when the same is positioned to clamp the cap 3 tightly upon the jar neck.

In effecting my novel closure, a cap 3 is superimposed upon the jar neck and so that its gasket 5 bears upon the upper edge of said neck. The bail is then applied laterally to the jar neck and the cap, whereupon the terminals 10 will spring into the groove 2 of the neck and embrace the neck in such manner that there is no liability of casual displacement of the bail. The cam lever 7 is then moved into its working position and so that the protuberance on the lever bears against the upper side of the cap, whereupon the cap will be held under strong pressure against the edge of the neck and the jar will be hermetically sealed.

With the jar closed, as stated, there is no liability whatever of casual opening of the jar. When, however, it is desired to gain access to the contents of the jar it is simply necessary to throw the cam lever 7 into its idle position, and then withdraw the bail laterally from the neck and the cap, whereupolp the cap may be readily lifted olf the neo As will be apparent from the foregoing, our novel closure, notwithstanding its practical advantages, is extremely simple and inexpensive in construction and is well adapted to withstand for an indefinite period the usage to which fruit jars and the like are ordinarily subjected. Having described my invention, what I claim and desire to secure by LettersPatent, is: V

1. As a new article of manufacture, abail for use jar closures, comprising a crown bar, arms depending irom said bar, and lateral curvilinear temninals ,l1av,ing outer portions reaching horizontally in one directionfrom the said arms, bights and inner portions; the inner portions being longer than the. outer portions and reaching reversely beyond and in the opposite direction from the arms of the bail.

2; The combination ofa-cap having a central concavity in its upper side, a bail straddling the cap, and a lever pivoted on the bail and having a cam head to clamp the cap and also having a handle the rear end 20 of which is provided with a pendent portion to bear on the cap and the upper portion of which is formed by a rearwardlyextending finger piece.

In testimony whereof I afiix my signature.

HERBERT ZIERLEIN.
