JAR-WRENCH.
SPECIFICATION forming part of Letters Patent N 0. 718,174, dated January 13, 1903.
Application filed March 14., 1902.
T0 aZZ whom, it may concern:
Be it known that I, EDWARD F. TIEMANN, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvementsin Jar-Wrenches, of which the following is a specification, and whichare illustrated in the accompanying drawings, forming a part thereof.
This invention relates to a wrench which is designed to be used for removing or unscrewing the covers of fruit-jars; and it has forits object to provide a device of this character which shall be simple in construction, and therefore inexpensive of manufacture, and in the use of which jar-covers which have become firmly fixed from long standing may be readily removed.
The invention consists of the parts and arrangement of parts hereinafter fully described, particularly designated in the claims, and which are illustrated in the accompanying drawings, in which Figure 1 is a plan of a jar-wrench constructed in accordance with my invention. 1 Fig. 2 is a detail of one of the handles of the wrench. Fig. 3 illustrates a blank from which such handle is made, and Fig. 4shows the manner of using the wrench.
The wrench comprises generally a pair of handles 10, to one end of each of which is attached one end of a wire or band 11, coiled dles. Preferably the handles are made of sheet metal stamped out in the form of blanks, as illustrated in Fig. 3, each of said blanks being provided with curved recesses 12 at opposite edges thereof, so that when it is folded longitudinally upon itself the curved portions will coincide. An aperture 13 is provided beyond the curved portions, and a tang or projection 1 1 is also formed at one edge of the blank and is designed to be bent, as shown in Fig. 2, to bridge the space between the two leaves of the blank when the latter is folded. The handles are disposed with the edges toward each other, and the wire 11, en-
Serisl No. 98,257. (No model-3 gaging'the aperture 13 of one handle, passes between the leaves of the other handle and behind the tang 14 thereof, thence in the form of a loop between the leaves of the first-mentioned handle and behind its tang 14, and finally attached to the second handle at its aperture 13.
When the wrench-is used, it is placed upon the cover of a jar, as shown in Fig.4, the wire encircling it and the curved portions of the handles engaging the sides thereof. Pressure on the extremities of the handles tending to force them together will separate the ends of the wire, and the handles being fulcrnmed on the jar-cover a powerful leverage may be secured, so that the cover will be firmly grasped by the wire and may be readily turned. During the operation the jar may be held by the free hand or in any other manner.
The tangs 14 serve to prevent the wire from becoming disengaged from between the leaves of the handles and to guide the same when the handles are moved. 1
The wrench may also be used for tightening jar-covers and also for holding jars while being filled, as well as for carrying them.
I claim as my invention- 1. In a device of the character described, in combination, a pair of handles and a band having its ends crossed and attached to the outer ends thereof, the said band extending in the form of a loop intermediate of the handles and between the points of attachment of the band and the opposite or grasping ends of the handles. A
2. In a device of the character described, in combination, a pair of handles each of which comprises a blank folded upon itself, a tang bridging the space between the leaves thereof, and a wire loop located between the handles and held and guided by the said tangs, the ends of the wire loop being crossed and attached to the ends of the handles.
