JAR WRENCH Fild June 23, 1936 Patented June 15, 1937 UNETED STATES ATET OFHQE JAR WRENCH Application June 23,

3 Claims.

This invention relates to wrenches primarily designed for the removal of jar caps, and the general object of the invention is to provide the handle of the wrench with a plurality of jar cap a engaging members of difierent sizes or diameters, the handle of the wrench being so connected to these jar engaging members that as the handle is closed, the particular jar engaging member in use may be contracted around the jar cap to I either put the cap in position or remove it from a jar.

Another object of the invention is to provide a construction of this character in which the outermost jar engaging member is formed integral with a the handle members and in which a plurality of successively smaller jar engaging members are pivoted within the loop of the first named engaging member so that they may be turned down out of position when not wanted, to permit the engaging member which fits the jar being opened or closed, to be used.

A further object is to so form the ends of the handle members that the handle members may be used for removing the rubber gaskets or washers which are commonly used on jars such as Mason jars, between the jar and the cap.

Other objects will appear in the course of the following description.

Our invention is illustrated in the accompanying drawing wherein:

Figure l is an edge face view of the wrench;

Figure 2 is a longitudinal section of the wrench with two of the cap gripping portions raised out of operative position;

Figure 3 is a fragmentary inside face view of the extremity of one of the handle members.

Referring to the drawing, H3 designates an open ring-shaped member which describes a segment of a circle and terminates in two outwardly extending handle members II and these handle members being shown as being formed integral with the cap clamping element Ill. One of the handle members, as H, adjacent its extremity is bent inward at 12 and then extends outward to form a beveled edge l3 for a purpose to be later stated, the inner face of this portion l3 being knurled or toothed slightly, as at M. Extending through the handle members H and ll adjacent the clamping member Ill is a pin l5, which pin is headed at its ends, as at 16, and passes loosely through openings in the handle members H and H Disposed within and approximately concentric to the clamping member I is a smaller clamping member ll, which is arcuate in form and has 1936, Serial No. 86,854

its ends extending toward the extremities of the handle members II and He, as at !3. Similar clamping rings l9 and 20 are disposed within the clamping ring ll and approximately concentrio to each other, these clamping rings having the portions !8 which extend toward the extremities of the handle members I! and H and through which the pin lE-passes. The clamping members Hi, ll, [9 and 2B are resilient and these members are urged to an expanded condi- 10 tion by reason of their resilience, the expansion of the members being limited by the heads l6 of the pin l5. It will be obvious now that if the handle members H and M be grasped by the hand and forced together, that one or all of the clamping rings I0, ll, l9 and will be contracted and that when pressure on the handle members is released, the clamping rings will expand to the extent permitted by the pin l5.

If it be desired to use the outermost clamping ring l9, all the other rings may be turned out of the way and the clamping ring Ill be used for screw or other caps having a relatively large diameter, and that if it be desired to use the next smaller diameter as, for instance, the ring [1, this ring is turned into the plane of the ring 10 while the inner rings l9 and 2B are turned out of the way, and this ring l9 clamped upon the object. The same operation is used where rings l9 or 2!) are desired. By having these rings of different diameters, it is obvious that the wrench may be used on jars, bottles or other containers for the removal or placement of caps or closures thereon without regard to the differing diameters of the stoppers, caps or closures, and that thus this device is adapted for use with containers, the caps of which have various diameters, it being understood, however, that the cap IE! is intended for the caps of standard containers having a standard diameter. 0

Certain containers have a cap which is screwed down or forced down upon a rubber gasket. These caps or closures are often times difiicult to remove because of the suction with which the caps are held down upon this gasket, and a knife or like implement must be inserted between the rubber gasket and the cap or closure in order to remove it. In our construction, the wedge-shaped extremity H! of the handle member I l is adapted for this very purpose, to be inserted between the gasket and the cap and to pry upward on the cap or on the gasket itself.

We have illustrated the handle member i as terminating short of the handle member H and as having riveted thereto a strip of metal designated 2| which extends from the handle member Il to a point opposite the extremity of the handle member II, and is then extended toward the clamping end of the handle member H This strip of metal 2| is bent laterally, then outward, then at right angles to the length of the handle member Il then inward and laterally, and rivet 22 extends through the two thicknesses of this strip. A second strip 23 is also riveted to the outer face of the handle member H and extends into approximate contact with the refolded end of the strip 2 I. The inner face of the loop 24 thus formed is knurled, this knurled face confronting the knurled inner face of the portion l3 or handle member I I. By inserting the chiselpointed or wedge-shaped end I4 into the space between the rubber gasket and the jar cap and then clamping the jar cap between the knurled surface on the loop 24 and the knurled surface on the inner face of the portion 13, the jar cap can be grasped and removed Without touching it with the fingers. Disposed between the returned end portion of the strip 2| and held in place by the

rivets

22 and 25 is a member 26 which at one end extends below the loop 24 and is then extended parallel thereto, the edge of this member being sharpened and the member being pointed at its extremity so that it constitutes a can opening tool, the point of the blade 21 being inserted through the can While the loop 24 constitutes a head adapted to rest upon the top of the can while the whole device is oscillated so as to cause the blade to cut the can in the manner of an ordinary can opening blade. The member 26 also extends above the loop 24 and rearward thereof, and is curved to form a hook 28 which constitutes a bottle cap remover, the loop 24 constituting a head to rest upon the top of the bottle cap and fulcrum against it while the hook pulls the bottle cap off.

It will be obvious that this device provides in one structure, means for opening a large number of closures of different character, and that it may be used for placing jar caps on jars, as well as removing the caps therefrom.

While we have illustrated certain details of construction and arrangement of parts which We believe to be particularly effective, we do not wish to be limited to these details except as defined in the accompanying claims. Thus it is within the purview of our invention to provide more clamping members than the four which are shown, and to provide a nest of smaller clamping members to open and close small containers. The members l0, l1, l9 and 20 are for the purpose of opening and closing containers such as Mason fruit jars and other similar jars having caps which screw down or which will unscrew. The terminal portion l4 of handle member I l and the knurled portion 24 are for the purpose of pulling out rubber gaskets on jars which have unscrewable caps or covers as, for instance, the Ideal or Atlas jars. In many cases where a person tries to open jars of this type, the suction will hold the cap very tenaciously to the jar. The parts l4 and 24 will be used to loosen the gasket or washer, break the compression and remove the cover.

What is claimed is:

1. A cap wrench, including an outer substantially arcuate clamping member having opposed handle members extending from its ends and a plurality of approximately arcuate clamping members, successively decreasing in diameter, disposed Within the outer clamping member and each having shank portions at its ends disposed approximately parallel to the handle portions of the outer member, all of said members being resilient, the resilience of said members urging their ends outward, a pin extending loosely through the handle members and through the shank portions of the inner clamping members and pivoting the shank portions of all the inner clamping members to the handle members for movement into or out of the plane of the outer clamping member, said pin permitting the compression of the handle members towards each other and the corresponding contraction of the clamping members.

2. A cap wrench, including an outer substantially arcuate clamping member of resilient material having opposed handles extending from its ends and an inner arcuate clamping member smaller in diameter than the first named clamping member and normally disposed Within said member and in the same plane thereas, the inner member having shank portions at its ends extending into the space between the inner ends of the handles, the resilience of the clamping members urging their ends outward, and means pivotally engaging the handle members with said shanks but permitting the handle members to be forced towards each other to thereby contract the clamping members.

3. A cap wrench, including an outer substantially arcuate member having handles extending from its ends and a plurality of inner arcuate clamping members each having its ends operatively pivoted to the handles for independent movement into or out of the plane of the first named clamping member, all of the clamping members being of resilient material, the resilience of the material urging the ends of all of said clamping members outward and urging the handles away from each other.
