Y Specification of Letters Patent. Patented March 17, 1908.

Application filed. ay s, 1901. Serial No. #172,593.

To all whom it may concern;

Be it known that L ALFRED W1LKI N,.a citi- .zen of the United States, and a resident of 'the city of New York,

ough of Richmond, in the county of Rich mond and State of New York, have invented a new and Improved Preserving Jar, of

which the following is a full, clear, and exact description.

.Thepbject of the invention is the elimination of recognized defects in the preservmg ]8.I or vessel as ordinarily used, among which, for exam 1e, are the use of rubber for 'valves and gas ets, which furnish nestin places for the pripagation of germs; the 18.01% or the escape of air or other gases from the jar or vessel during the canoperation; the likelihood of-the bacteria of t e air finding access to the interior of the vessel and the difliculty of removing the cap from the vessel when sealed.

I am enabled to overcome the above objections ymy invention, one embodiment of which is hereinafter disclosed.

Reference is to be had to the'accompanying drawings forming a part of this specification, in which similar characters of refer ence indicate corresponding parts in all the" es. Figure 1 is a central, vertical section through the preferred forin of my invention;

g. -2 is a plan of the c ap or cover for the vessel'; Flg. 3 is an inverted lanof the same;

4 1s a plan of the ve'ssei is a view of a disk of paper or other suitable material which is employed in the preservoperation; 1 I he invention comprises a' ar or vessel body 1 of suitable size and shape, that shown being uniformly cylindrical on the exterior and, constructed with a contracted -portion 2 at its upper end forming the jar than the outer wall and shown in Fig. 1,is constructed with a with a thickened the-bottom edge thereof. I 'the'cap fi is preferably formed slig tly con-' v neck. In the top face of this neck, an annular groove 3 is formed, the inner wall 4 of which is made somewhat higher I provides a seat for receiving a cap or cover 5. This cap, as best flange 6 on its under face, said'flange being exteriorly threaded and entering thegroove 3 when the ca is seated in osition'. I The dimensions of t egroove and an e are such that the flange will be separate from the walls of the grooveat both sides as well as at The 'to face of New Brighton, bor

' ter to be or jar, and Fig. 5

into the groove 3 formed in the jar. vterior of the or; depression 7 when the capis in place, through a perforation SQpassing through the center of the cap, sai perforation being closed by a disk 10 of pa er or other suitable material, shown in detai in Fig.5.

In the use of the jar, the fruit or other matcooked in't e ars or in a separate vessel, in the latter case bein placed in the jars until they are well filled, the cap 5 quite hot is then Ia'c'ed in ig'. -1". T e disk 10 should then be dipped in. araflin' or other similar sealing material and placed in the cup 7 over-the top of the perforation 9. .The sealing mixture, which araflin,. is I thereafter- 'while" 1s ordinarily uite'hot and'm a'liquid state, poured into .t e on 7 and overflows through the grooves 8 and lls the groove 3 at the inside and outside of the flange 6 on the cap. Steam, air

or other gases rising from the fruit while the parafiin in' thecup 7 is in the liquid state, passes through the perforation 9 under the valve 10 and esca es. As there is a larger portion of materia in the cap around its center than at the circumference of the cap, the paraffin in the on 7 will remain in the iquid condition longer t an elsewhere. When the temperature lowers, theparaflin hardens first in. the annular groove 3 andthereafter in the on 7, leaving the jar hermetically sealed. lgh small nail or similar device is thrust through the parafiin into the vent-cup and through the perforation 9, .thus admitting the*8.l!. By now slightly warming the cap, the paraffin loosens its hold on the thread. of. .the flange, which may then be easily screwed ofi. c It is evident that the invention as illustrated in the accompanying draw ng and as hereinbefore described 1s=s1Isce tlble of numerous modificationsfalling wit the scope of"the annexed-claims.

Having thus described my invention I claim as Patent:

- 1. A'preserv'ing bodyhaving an annular groove 1n its upper end, and a cap seated over said'body aving a-threaded' flan e projecting into said groove, said threade flange being externallyical and construct-ed with a vent-cup or depression 7 atits center, from which lead :a 3 number of radiating grooves or channels" 8;.

The in-' jar communicates with the cup Y reserved, after being properly I osition on each jar, as shown in en the jar is to be opened, a pin,

jar or vessel, comprising a and internally spaced from the walls of said groove whereby when the groove is filled with a sealing material it will enveldp said flange both .exteriorly and interiorly'.

2. A preserving jar or vesselcomprising a body having an annular groove in its upper end, a cap seated'over said body, having a recess forming a vent-cup which co'mmunicates with said groove, and a threaded flange 5. A preserving jar or vessel comprising a body having an annular groove in its ,upper end, a cap seated over said body having a recess forming a vent-cu which communicates with said groove, a ange projecting from said into said groove, and a seali materia substantially filling said cup an groove.

6. A preserving jar or vessel comprisinga projecting from the cap into said groove, body having an annular groove in its upper said threaded flange being externally and inend, a ca seated over said body having a reternally spaced from the walls of said groove. cess wit a erforated bottom'forming a 40 whereby a sealing material introduced into vent-cu an a flange projecting into said the groove will envelop the flange at both groove i rom said ca said flange being exsides i ternally and internal y spaced from the walls 3. A preserving jar or vessel comprising a of said groove whereby a sealing material inbody having a groovesurrounding the neck troduced into the groove will envelop the thereof, a cap seate'd over the neck" of said flange at both sides, and said ca havin body, having a recess forming a vent-cup radial channels or grooves leading rom sai which communicates with said groove, and a projecting portion formed on the cappassing into said groove.

4. A preserving jar or vessel, comprising a, body having an annular groove .in its upper and, a ca seated oversaid body having a threaded ange projecting into said groove, end a" sealing material said groove and entering the threads on sai 'flange.

cup to the annular groove in the top of the vessel. 1
