W tlorney Patented Mar. 18, 1930 JOHN SGI-ILEINZER, or RoonEs'rER, uriwxonx TOOL FOR REMOVING cars FROM JARS 1 Application filed. April 6, 1928. Serial No. 267,971.

The object of this invention is to provide a new and improved wrench or handle for removing the caps from glass jars, etc.

Another object of the invention is to make the wrench of sheet metal and make it so that it will fit two different sizes of caps.

Another object is to make the wrench with a central disc and provide gripping fingers or lugs on the rim of the disc that extend both up and down from the central disc which lugs interchangeably serve as gripping fingers to grip the cap, or as a handle by which the wrench may be more conveniently turned. These and other objects of the invention will be fully illustrated in the drawings, de scribed in the specification and pointed out in the claims at the end thereof.

In the drawings: 7 v

Figure 1 is a perspective view of the glass jar with the wrench suspended above it ready to engage with the cap on the jar.

Figure 2 is a side elevation of the jar with the wrench in position on the cap. 7

Figure 8 is a side elevation of the wrench in which one set of fingers are made corrugated so as to form a mutilated thread by which they may be screwed into engagement with the cap. The other set of fingers are made eccentric to the rim so that on one side so they will present an edge to the cap which is better adapted to engage the cap.

Figure 4 is a detail perspective view of a modified form of one of the gripping fingers of the wrench.

Figure 5 is another detail perspective view of a modified form of one of the gripping fingers of the wrench.

' like reference numerals In the drawings indicate like parts.

In the drawings reference numeral 1 indicates a glass jar having a metal cap 2 thereon which jar and cap is similar to what is ordinarily used in dispensing mustard, jelly, peanut butter,.etc. 8 indicates the wrench having a disc in the center on the rim of which are formed three radial extensions 4, 4, 4 on the outer end of which are formed upturned fingers 5, 5. Also formed on" the edge of the disc of the wrench are three clownwardly extending fingers 6, 6, 6. The fingers 6, 6,6 are spaced 'apart1ona smaller circle having a shorter diameter and the fingers 5, 5, 5 are spaced apart on a larger circle having a longer diameter. The wrench is formed of a single sheet of metal in which the six fingers are stamped out integral therewith, the fingers 5, 5, 5being turned up and the fingers 6, 6, 6 being turned down. The fingers 6,6, 6 .are used to engage a cap of small diameter and the fingers 5, 5,, 5 are used to engage a cap of larger diameter. The Wrench is used by'simply forcing the fingers down over the sides of the cap until the disk of the wrench rests on'top of the cap. The operator'will then press the lower fingers'in against the cap and will turn the wrench, using the upwardly extending fingers as handles by which to force the turn'ingof the wrench, and all 01": this can be done with one hand.

Ordinarily the downwardly extending fingers will engage the cap firmly enough to hold it to force the turning ofthe cap without pressing the fingers of the wrench together with the fingers of the hand. This is due to 75. the fa'ctthat the caps of jars'are ordinarily provided with abeaded rim which extends outwardly from the glass jar and which will cause the gripping fingers to spring out thus causing the wrench tomore securely engage the cap, and hold it in engagement therewith with yielding pressure. 1 By turning the cap and wrench on the jar, the cap can easily and quickly be removed from the jar. V In Figure 3 I have shown one set of the grippin'g fingers 8, 8, 8 corrugated, the corrugations forming a mutilated thread which engages the beaded edge of the cap 'andjserves to draw the wrench down firmly on the cap' 9 i and hold the wrench firmly in engagement with the cap so that thecap may be positively turned thereby.

I have also shown the upwardly extending fingers 9, 9, 9 formed slightly eccentric to a V tangent to the rim atthe point where the fingers are placed. With the fingers formedin thisway the forward edge tends to cut into the cap or the beaded edge thereof thus making a more positive engagement therewith by which to' force the turning of the cap on'the' jar and secure'the removal thereof. I I I In Figure I have illustrated another'modifiedform of the gripping fingers which is made by con'caving the outside of the fingers as illustrated so that a curved convex surface is'pre'sented to the capwhen the'fipgers'coine in'contact therewith.
