Patented June 19, 19230 mm are ALFRED E. WIT'I'IG, OF ROCHESTER, YORK- ATTACHMENT FOR JARS.

Applieationfiled October 30, 1922. Serial No. 597,739.

To all whom it may cancer mi Be it known that I, ALFRED E. WITTIG, a citizen of the United States, and resident of Rochester, inthe county of Monroe and 6 State of New York, have invented certain new and useful Improvements in Attachments for Jars, of which the following is a specification.

The present invention relates to an at- 1 tachment for jars, such as fruit jars of the type in which the cover or closure is provided with a bail-receiving recess and two camming portions on opposite sides of the recess over which the bail is caused to pass to enter into the bail receiving recess. An

object of this invention is to provide an attachment which will cooperate with these camming portions and the walls of the recess for the purpose of causing the cover or closure to be held in tight cooperation with' the jar by the bail, after the la ter has become expanded or stretched from use.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described: the novel features being pointed out in the appended claims.

In the drawings: v Fig. 1 is a plan view of'a ar equipped with the present invention;

Fig. 2 is a fragmentary sectional view on the line 2--2, Fig. 1; .Fig. 3 is a sectional view on the line 33, l F i 4 is a view of the under side of the attac ment; and

Fig 5 is a perspective view of another embodiment of the invention. I

Referring more particularly to the drawings, 1 indicates the jar and 2 the cover or closure which has its edge seated on a pack-.

ing 3 resting on a seat 4 at the upper end of the jar. This cover is held in place by a swinging bail 5 of known construction plvotally connected at 6 to a swingmg member 7, which tends to draw the bail with pressure on the closure 2. The closure has on its top a pair of cam portions 8 extending in opposite directions-from a notch or recess 10.

59 In operation the bail is forced upwardlyover one of the cams portions to enter the notch or recess 10 after which swinging member 7 is swung downwardly to place pressure on the bail, all of which form part of a well-known construction and is not claimed herein.

The clamping means forthe top 2 becomes in time so weak-or stretched that it will not place the properpressure upon the top and, in order to obtain this pressure, this attachment is provided. Two embodiments of this attachment ar illustrated, one in'Figs. 1 to 4 and the other in Fig. 5A In the embodiment illustrated in Fig. 4, the attachment is formed from sheet metal to provide a circular substantially inverted cup-shaped portion 11, and two arms 12 extending from diametrically opposite sides-of the -cup'-' shaped portion and downwardly with reference to the same. At or near the center of the attachment a transversely extending groove 13 is provided, in the top surface of the circular-portion 11, and on the under side, of the attachment two longitudinallyextending grooves 14 are provided, these grooves leading from the transversely extending groove or recess to the ends of the arms. The grooves 14 receive the cam portions 8, while the projection formed between th inner ends of the longitudinal grooves by depressing the top surfacesof the attach the recess 10. It, will thus 'be seen that the arms of the attachment act' as cam surfaces for the bail andserve to hold the attachment against transverse movement'of the bevell-ing projections of the cover or closure. The transversely extending recess or groove serves as a locking recess for the bail and the projection formed on the. under side of the attachment beneath the transversely. extending groove serves to enter the recess be.- tween the cam portions on the cover to prevent the longitudinal movement of the attachment on the cam portions of the cover.

, ment to provide the transverse groove lies in a In the embodiment shown in Fig. .5, the

parts are the same except that the-central portion is in the form of two laterally. projecting arms 11, which take the. place of the inverted cup-shaped portion 11 of the embodiment shown in Figs. 1 to 4:. f

From the foregoing it will be seen that there has been provided anattachment for jars of the type described which will permit the obtaining of a stronger clamping action on the cover after the clamping bail has become weakened.

What I claim asm ..-invention and desire; to secure by Letters atent is:

1. A jar attachment 'comprisi'ng'a central portion provided with a transversely extendlng bail-receiving recess and two arms extending from said central portion and having means for interlocking with the cam portions of a jar closure.

2. A jar attachment comprising a central portion provided with a transversely extending hail-receiving recess, and means for interlocking with the cam portions of a jar closure.

3. A jar attachment comprising a central v portion'provided with a transversely extend- I 4. A jar attachment comprising a central portion provided with a transversely extend-' ing bail-receiving recess on one side of the attachment, and two arms extending from said central portion and having each alongitudinally extending recess on the opposite side of the attachment, said central portion also having a projection on the under side between the longitudinally extending recesses to enter the bail-receiving recess of the jar closure.
