JAR OR BOTTLE CLOSURE.

Specification of Letters Patent.

Patented Jan. '7, 1913.

Application filed May 14, 1912. Serial No. 697,241.

To all whom it may concern:

Be it known that I, ALBERT H. EMERY, a

citizen of the United States, residing in the.

city of Stamford, county of Fairfield, and State of Connecticut, have invented a new and Improved Jar or Bottle Closure, of which the following is a specification.

My invention relates to improvements in the construction of glass jars, bottles or similar receptacles, and particularly to the closure of such receptacles as hereinafter described and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification.

Figure 1 shows a plan of the jar and its cover secured in place; Fig. 2 shows the upper part of the jar and its cover in section; and Fig. 3 shows a side elevation of the upper part of the ar and its cover secured in place.

This invention relates to the'class of jars in which the cover is secured in place by the help of lugs on the-cover and neck of the bottle or jar.

My improvements relate to a method of fastening the cover securely and to improvements by means of which it can be removed easily after standing until the packing sticks Similar numerals of reference indicate corresponding parts in all figures of the drawin s.

1 is t e upper part of the jar and 2 is the cover. a

3 are two lugs on the cover of the jar.

4 are two lugs on the neck of the jar.

5 are two bent'springs, bent to provide two branches, between which a pair of lugs on the jar and cover may be embraced to secure the cover to the jar, and hold it I tightly against the packing ring 6 which is placed in a recess in the cover.

The jar and its cover may be made of glass or earthenware or any suitable material. I usually make it of glass. The springs 5 will usually be bent in the form shown in the drawing. The upper lugs 3 are slightly smaller where the springs rest on them than at the outer end, which prevents their slipping off easily. The spring may be made of any desired section. The ends are bent out, so that when the cover is placed on the jar and the spring 5 held in a vertical position, as shown by dotted lines in Fig. 3, the springs may be pushed onto the lugs are preferably such as to bring the spring-bearing faces farther apart than the width of the lugs so as to develop pressure by rotating the spring into the clamping position. They should give pressure enough on the packing 6 to seal the jar when desired, which is always the case when they are used in preserving fruit.

The added atmospheric pressure as the fruit cools usually causes the packing ring 6, especially if made of rubber, to stick firmly after the cover has been closed some time. When it is desired to open the jar the springs 5 are each rotated to the vertical position shown in dotted lines in Fig. 3 and then removed. A knife blade or other suitable implement is then placed between two of the lugs 3 and 4 and a little prying movement given which breaks the seal, allows the air to enter and relieves the sticking of the packing ring. The coveris then readily removed.

There may be two sets of the lugs 3 and r 1 as shown in the drawing, or there may be more sets if desired.

I claim 1. A jar or receptacle provided near the open end with a plurality of outwardly projecting lugs and a cover for said jar provided with an equal number of outwardly projecting lugs, the lugs on one part registering with the lugs on the other, said jar and cover being adapted to receive a packing ring between them and a separate spring acting on each pair of adjacent lugs, said spring being made in the form of a loop having a pair of opposed arms which, when in looking position rest upon the lugs and draw them toward each other and develop pressure upon the packingring.

2. A jar or receptacle provided near one end with a pair of outwardly projecting lugs placed opposite each other and a cover for said jar provided with a similar pair of lugs and springs acting on said lugs to hold the cover firmly on the jar, each of said springs being made in the form of a loop having a pair of opposed arms which, when in looking position rest upon the lugs and draw them toward each other.

3. A jar or receptacle provided near the open end with a plurality of outwardly projecting lugs and a cover for said jar provided with an equal number of similar lugs and springs acting on said lugs to hold the cover firmly on the jar, each of said springs being made in the form of a loop having a pair of opposed arms which, when in locking position rest upon the lugs and draw them toward each other, each pair of lugs being formed to have the faces upon which the springs rest, when in locking position, spaced apart a distance greater than the width of the lugs and so proportioned that the loop springs when in a vertical position keep the cover from turning and when turned down to working position hold the cover tightly on the jar.

4:. A jar 0r receptacle provided near the open end with a plurality of outwardly projecting lugs and a cover for said jar provided with an equal number of outwardly projecting lugs, the lugs on one part registering with the lugs on the other and a separate spring acting on each pair of adjacent lugs, said spring being made in the form of a loop having a pair of opposed arms which, when in locking position rest upon the lugs and draw them toward each other and hold the cover against the pacl ing ring of the jar; said spring having the two arms of the loop curved to substantially conform to the curvature of the cover.

The foregoing specification signed at Stamford, Conn. this 11th day of May 1912.

ALBERT H. EMERY. In presence of two witnesses:

GEORGE R. CLosn, MABEL E. HAMILTON.
