To allwhom it may concern: Be it known that I, EDWARD C. REDS, a citizen of the United States, residing at Kansas City, in the county of Jackson, and State of Missouri, 'liave' invented certain new and useful Improvements in Jar- Closures, of which the following is a specification, reference being had to the accompanying'drawings' This invention relates to the art of jar closures, and particularly to a closure, in which a novel construction of securing means for the closure. is involved It has been found that using the type of closure particularly used on jars known as the Mason, great difficulty is experienced in remoiing and applying the closure, necessitating the use of a; spanner wrench. Furthermore, when a wrench is not used, it would require heating the closure, to rupture the tight fit. V

The present in.ei1tio11 aims to avoid these disadvantages by providing a having means for supporting yieldablev members, for urging constant pressure yieldably on the closure, in. combination with means. whereby this pressure maybe increased or decreased, and yet at the same time provide.

a jar closure construction which may be easily opened, and also to provide one that can be easily applied to the jar, and further to insure requisite sealing of the contents.

The invention further aims to provide supporting means anchored to the neck of the jar and carrying members for exerting yieldable pressure, the closure proper in turn supporting means to cotiperate with the members, whereby their combined yield-able tensions may be increased or decreased, whereby the pressure upon the closure may be increased or decreased.

l Vhile the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view in perspective of a fruit jar showing the'in'iproved construction ap plled.

Fig. 2 is a vertical sectional view through.

sameon line 2-2 of Fig. 1.

Fig. 3 is a plan view. Fig. 4 is an enlarged detail view of the clamping means to be secured about the neck of the jar, for supporting the yieldable members;

Fig. 5 is a detail .,view in perspectiveof the upper open end of the neck portion of the Jar.

Referring more especially to the drawings 1 designates a fruit jar,- which may be any suitable shapeor configuration. The jar is provided with a contracted-neck 2 having an annular rib 3, and 4 denotes a metallic band designed to fit'between the'rib and where the body of the jar merges into the neck. This band at is constructed from spring metal, and its ends 5 are provided. with laterally extending ears 6, to receive a screw or bolt 7, provided with a nut 8, whereby the band may be fitted tightly to the neck of the jar below the rib Risingupwardly from the bandand riveted thereto as at 9 are upstanding ears 10. These ears are arranged fat' points diametrically opposite each other, and theirupperportions aretwisted, as shown at 11, so that the cars will extend. angularly from the circumference of the jar closure.

A closure 12 is provided and has a top wall 13, and an annular flange 14:. The

marginal edge of the flange 14: has a bead 15, between which and the uper edge of the rib 3 of the neck of the jar, a rubber ring or gasket 16 is interposed,-thereby insuring a liquid as well as an air-tight joint between the closure and thejar. The closure telescopes the upper part of the neck, and adjacent the inner surface of the top of the closure a porcelain lining 17 is arranged. This lining 17 is secured in the closure adjacent its topwall by means of the bulges 18 formed in the flange of the closure, and constitutes a reinforcement for the closure. Rising upwardly and concentrically with the closure is a threaded stud 19, on which a wing thumb nut 20 is threaded.

Pivotally mounted in the upstanding ears 10 of the band 4 are bail members 21.. These bail members are designed to be constructed tilted outwardly. A sharp instrument, such as the edge of a knife or the like may then so as to engage the rubber gasket or ring between its beaded edge, and the rib, the bail members are disposed, so that their arms will Overly and contact with the marginal upper edge of the closure, as indicated at 22, and so that the central parts of the arches of the bails will be disposed under the wing nut. It is to be noted that when the nut is adjusted sufliciently so as to bear down upon the bails, which, as shown, are angularly disposed, and engaging the marginal edge of the closure, will bearyieldably and exert pressure on the closure sufficiently, to clamp its lower beaded edge incontact with the gasket or rubber ring, insuring a secure fluid and air-tight joint. By a construction of this kind, it is obvious that when it is desired to open the jar to gain access to the .contents thereof, it is a very easy matter to unscrew the wing nut. The pressure will be relieved upon the bails, which are free to be be inserted between the beaded edge and the glasket "or rubber ring, breaking the seal [7 erebetween, subsequently to which the closure is free to be lifted or removed from the neck of the jar readily allowing access to the contents. 1 r p The invention having been set forth, what is claimed-as new and useful is: 7' .1. In a jar closure, the combination wit theneck of a jar, of a closure fitting the neck, a tight-joint between the closure and the neck, diametrically oppositely disposed yieldable loops contacting with and overlying the edge of the closure, supporting means for said loops, and means carried by the. olosureand being adjustably movable in I or decreased.

a vertical direction axially with the closure for cooperating with the yieldable loops to increase or decrease the pressure on the closure.

2. In a jarclosure, the combination with the neck of a jar, of a closure 'fitted thereto and provided with a fluid or air-tight joint therewith, diametrically oppositely disposed ried by the closure concentrically therewith,

diametrically opposedv yieldable members having their arms overlying and engaging the marginal edge of the closure, a clampmg band around the neck and having'means for pivotally supporting said yieldable members, and a devicethreaded onthe upright and engaging and cooperating with the yieldable members, whereby their combined pressures on the closure may be increased In testimony whereof I hereunto 'alfix my signature in the presence of two witnesses.
