To all whom it may concern:

Be it known that I, CHARLES H. SPOONER, a citizen of the United States, residing at Charlestown, in the county of Sullivan, State F of New Hampshire, have invented a new and useful J ar-Closure; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

Thisxinvention relates to an improved jar closure, whereby jars, bottles and the like may be securely sealed when preserving.

One of the objects of the invention is to effect the closure of jars and like containers by means of a single piece appliance in conjunction with a flexible sealing ring.

' the 'top of the closin flat and of an outside A further object is to insure quick action, in the final closing of the receptacle and quick action in the releasing of the seal when it is desired to open the jar.

A further object of "the invention is to make easy the act of and maintenance of sterilization in products best prepared by placing them in the receptacle before cookmg.v

A. further object of the invention is to provide an-improved closure, of such char-.

i I ers whether filled or emptied.

The first three results or objects may be attained by screw means consisting of sextantally interrupted threads, either interof the container, the last object by making element essentially 'ameter equal to that of the container itself.

A further object of the invention is the provision of means between the contacting parts of the jar and the closure to prevent excessive spreading of the sealing ring.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

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

In the drawings Figure 1 is a sectional view through the top? of a preserving jar or container.

ig. 2 is a sectional view'through the closure for the jar in Fig. 1.

Specification of Letters Patent. Patented Aug. 31, 1920. Application file d my 9,1918. Serial No. 244,095.

Fig. 3 is a the closure.

Fig.4 1s an edge-elevation of the closure.

plan view of the jar without Fig. 5 is a sectional view through the upper open end of the jar showing the threaded connections externally arran ed.

without its closure.

Fig. 8 is an edge View of the closure in 6. r eferring more especially to the drawings -1 designates themouth end of a jar, the

inner wall of which is provided with threads? which are interrupted sextantally. For instance the threads are divided into sextants, three of which have threads 2, and three others or spaces .3-without threads. In other words the threads are cutaway or interrupted at three intervals, and 4 denotes a suitable closure, comprising a body 5 provided with a circular flange 6. .The. cylindrical face of the body is provided with threads interrupted sextantally, the 'sextants of threads 7 adaptedto enter the cutaway space 3 of the interior of the mouth end of the jar, so that by imparting a partial turn to the closure said threads 7 may interengage the sextants of threads of the jar.

When inserting the closure the sextants of threads 2 will enter the sextants or cutaway spaces 8 of the closure. The marginal edge of the month end of the jar is provided with an annular recess 9, the bottom of which is inclined, for the reception of the sealing rlng of any suitable material preferably rubber. The bottom of the flange 6 of the closure has an extension 10 the under face of which is inclined to engage the rubber seallng ring (not shown). The inclined faces of the parts 9 and 10 are provided, so

as to prevent outward bulge of the sealing ring. The threads 2 and 7 are V-shaped. In Figs. 5, 6 and 7 the threads 2 are square. or rectangular in cross section, and the sextant spaces?) are externally arranged on the jar. The threads 7 and the cutaway spaces or sextants 5" ofthe closure 11 are internallyarranged. In such structure of jars and closures the upper marginal edge of the jar in Fig. 7 is inclined as shown at 12, for the reception ofthesealing ring of rubber (not shown). The portion" 14:- of the closure 11 is designed to engage the sealing ring and hold it against the inclined portion 12, and the flange 13 extends into the cavity 15 of the closure 11.

In using this particular device the cover is 5 easily'placed in the initial position, with the threads of the closure engaging the sextants or spaces 3, and then by imparting a partial turn to the closure or cover the threads of the cover or closure may quickly mesh with those of the jar mouth, turning the closure or cover one sixth of a revolution to the final seal. Fruits or vegetables requiring to. be placed in the jars cold, the

cover may be at once placed'inthe initial position and allowed to so remain until sterilization is completed and then quickly turned to final position, thereby preventing air or any deleterious element from entering.

The invention having been set forth what is claimed as new and useful is The comb'nation with a ]3.1' having a mouth end provided with interior interrupted threads, of a closure comprising a body fitting into the mouth end and provided with interrupted threads to engage the threads of the interior of the mouth end, the

marginal edge of the month end having an annular recess, said annular recess inclining inwardly and downwardly and having lts lnner wall substantlally vertical, the body of the closure having an annular flange, said annular flange on its under face being provided with an annular recess, which annular recess inclines inwardly and upwardly, an

annular recess concentric with the recess of 'the under face of the flange and adjacent downwardly and inwardly and upwardly. In testimony whereof I ha'vesigned my name to this specification in the presence of two subscribing witnesses.
