ALEXANDER L. SCHRAM, or HILLSBORO, ILLINOIS, AssIGNoR To SCHRAM GLASS MPG.

00., OF ST. LOUIS, MISSOURI, A CORPORATION or MISSOURI.

FRU T-JAR.

To all whom it may concern: Be it known that I, ALEXANDER L SOHRAM, a citizen of the United States, and

resident of Hillsboro, Montgomery county, Illinois, have invented certain new and useful Improvements in Fruit-Jars, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to certain new and useful improvements in fruit jars and has for its primary object a fruitjar provided with a lid receiving flange and a gasket flange around its mouth a pair of bosses diametrically opposite each otherand a clamp ing means pivotally and slidably mounted in the bosses. V 7

A further object is to construct a fruit jar which has a wire' clamping means, this clamping means being pivotally and slidably secured to the jar, the sliding feature of this pivot part is that it gives additional throw to the wire which fits over the jar top and in this way a shorter arm or throw can be used, or in other words, a small amount of wire saved on each trimming which in the aggregate vwill amount to ,a considerable saving in cost and material.

In the drawings:

Figure 1 is a side elevation of my device Showing the clamping means inv locked position on the jar and showing means released by dotted lines. 7

Fig. 2 is a fraglnental view of the upper portion of a jar with the clamping mechanism removed. 1 I

Fig. 3 is an enlarged sectional view taken through one of the bosses and showing a portion of the clamping means secured therein.

In the construction of my device, I provide a jar having a body portion 4 and a neck 5, the neck 5 having around its upper end or mouth an upwardly projecting flange 6 which acts as a guide for the lid 7 and an outwardly extending flange 8 which acts as a support for the jar rubber or gasket 9. The neck 5 is further provided with a rib 10 and a pair of bosses 11. These bosses are formed integral with the neck and diametrically opposite each other.

The'rib 10 extends around the neck and is formed integral therewith as well as with the lid is clamped down.

the clamping the bosses. Its object is to prevent strainin" the neck of the jar when it isinolded.

v Specification of Letters Patent. Patented Sept. 1920. Application filed June 14, 1919. Serial No. 304,168. i

The bosses are furtherprovided with a re cess or depression 12 wlnch serves as a bear- 7 ing for the ends'13 of the lever wire 14. This lever wire is substantially U-shaped. Adjacent each end of the lever wire, I form the eyes 15 which receive'the inturned ends '16 of the lid clamping wire 17.

The recess 12 is practically semicircular in form (see Figs. 2 and 3) so that the surface 18 will form a sliding bearing'point for the end 13 of the lever wire 14.

The lid 7 is provided with acentral boss 19 and a pairof ribs 20. These ribs extend slightly above the top surface of the boss 19, their adjacent'ends forming a recess 21 in which the clamping wire is adapted to fit and preventits movement or shifting when As will be noted the ends 13 'ofthe, lever wire shift back and forthin therecess12.

(see solid and dotted positions-of clamping means inFig. 1) when the lid is clamped or released. This gives a much smoother and easier operating device than when a circular recess is used. The horizontalsurface 18 of the recess 12 eliminates any tendency of the end 13 from becoming dislodged when strain is put thereon due to the clamping of the lid. p v r It will be observed that the peculiar shaped. recesses in the bosses permit retainlng considerably more material above the pivot points 'of the lever wire than below,

this beingadvantageousfor the reason that when clamping the lid, the strain-on the ends 13 of the leverwire is upward and:

against the horizentalsurfacej18, this additional material obviating the ,tendency of, thatportion of the boss to chip or break out.

Encircling the flange G and adjacent-the flange 8 is a gasket retaining recess 8.. The

when any upward pressure takes place in the ar, the wire 17 will have a tendency to pull the lever wire 14 downwardly instead of raising it up, were the ends 16 on the opposite side of the ends 13, in which case the lever wire 14 would be raised and release the top or lid. 7

Having fully described my invention,

what I claim is: p

1. A fruit jar comprising a body and a re duced neck portion, the neck portion being provided with a lid receiving shoulder and a gasket retaining recess, a rib formed integral with the neck portion substantially midway between the body of the arand the 11d receiving flange, bosses formed on the horizontal upperwalls, a lid clamping wire having its ends inturned and seated in said recesses, so as to provide shifting pivot points for said wire, a lever wire, and an eccentric connection between the lid clamping wire and the lever wire.

2. A fruit jar comprising a reduced neck portion, the neck portion being provided at its upper edge with a lid receiving shoulder, a gasket retaining recess formed around said shoulder, a second shoulder formed adjacent the gasket'retaining recessand adapted to support the gasket, a rib formed'integral with the neck portion substantially midway between the body of the jar and the lid receiving flange, apair of bosses diametrically opposed formed in tegral with the neck portion and the rib, semi-circular recesses formed in the bosses the top portions of said recesses being in substantially horizontal planes, a U-shaped lever wire having its ends inturned and seated in said recesses soas to provide shift ing pivot points for said lever wire, a loop formed adjacent each end of the'U-shaped lever wire, a-lid clamping. wire substantially U-shaped in form and having. its ends inturned and seated within the loops formed in the lever wire, so as to iorm an eccentric connection between the lid clamping wire and the lever wire.

3. A fruit jar having a body a neck portion, the neck portion being provided around its mouth with flanges, a recess formed 'in one of said flanges for rebody and, a

portion and taining a gasket, a pair of bosses formed'integral with said neck portion and diametrically opposite each other, recesses formed in said bosses, said recesses having a horizontal top plane surface, a U-shaped lever wire provided with loops adjacent its ends and having its ends inturned and seated in said recesses so as to provide shifting pivot points for said lever wire, said ends adapted to fit within the recesses, a lid clamping wire U-shaped in form having inturned e nds,- said inturned ends adapted to be seated within the loops formed on the levenwire in com)- binat on with alld having a central boss and;

way between the body portion and the horizontal flange, a rib extending around the neck portion formed integral t'herewith and connecting the bosses, sald bosses being dim metrically opposite each other, a resess,

formed in each boss, said recess being. substantially SGInlClICilltlflIl form and; having its curved surface at the bottom, a! horizontal plane surface formed in the upper end of said recess, a'U-shaped' lever wire having inturned ends seated 1Y1 sald recesses so as to provide constantly shifting: bearing points for the ends otthe lever wire when the same is operated, loops formed in the lever wire adjacent the ends, a lid clamping wlre' U-shaped in form" having inturned ends, its inturned ends being seated in the loops formed in the lever wire; the inturned;

ends of the lever wire being adapted to it within the recess and adapted to contact with the flat surface thereof, soas to form" a sliding pivot point.

In testimony whereof I'have signed my' name to th1s speclfieatlon, 1n the presence'of' two subscribing witnesses.
