JAR LIFTER Filed May 16, 1935 2 Sheets-Sheet 2 I nventor Patented Mar. 3, 1936 UNITED STATES JAR LIFTER Joseph Andrlik, North Liberty, Iowa Application May 16,

1 Claim.

The present invention relates to a jar lifter and has for its object to provide a device of this nature which may be used not only for lifting jars but also has a wrench for unscrewing the caps from the jars.

Another important object of the invention resides in the provision of a device of this nature which is simple in its construction, comparatively inexpensive to manufacture, easy to manipulate, thoroughly eificient and reliable in use, and otherwise Well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of a jar and my device attached thereto.

Figure 2 is a similar view but taken at right angles to that shown in Figure 1.

Figure 3 is a horizontal section taken substantially on the line 3-3 of Figure 1.

Figure 4 is a detail section taken substantially on the line 4-4 of Figure 1.

Figure 5 is a prespective view of one of the jaw members.

Figure 6 is a detail sectional view taken substantially on the line 6-6 of Figure 1.

Referring to the drawings in detail it will be seen that this device includes two jaws A and B which are very similar in construction. I shall first describe in detail the member A and then point out the slight differences therefrom in member B.

The member A is formed from a single strand of resilient wire material and has an arcuate bight portion 5 merging at its ends into arms 66 disposed in spaced co-extensive parallelism, or rather approximately so and lying in a plane obtusely disposed to the plane of the bight 5. These arms 6 are provided adjacent the bight 5 with convolutes 1 forming eyes and between said convolutes and the ends thereof with other convolutes 8 to increase the resiliency of the device as a whole. The upper ends of the arms 6 merge into inwardly directed acutely disposed extensions 9 which in turn merge into trunnions Ill directed toward each other in alignment and having their terminals in abutment and a sleeve or grip member II is disposed thereover capable of being turned or rotated thereon.

The member B has its arms 6 shorter tha 1935, Serial No. 21,868

the arms 6, is provided with eyes 8 and I corresponding with the eyes 8 and 1 of the member A. The upper ends of the arms 6 are identical with the arms 6 and need no further explanation. The bight 5' corresponding to the bight 5, however, differs as will be noted from an inspection of Figures 1 and 2. The bight 5' is of a general arcuate formation but the central portion thereof has an upper curve and it merges into the arms 6' in an arcuate manner and is disposed in a plane which is substantially at right angles to the plane in which the arms 6 are disposed.

A bolt 14 extends through the convolutes or eyes 1 and I thereby pivotally connecting the two jaws together. It is to be noted that the arms 6 are spaced closer together than the arms 6 and in this way the device may be collapsed to a compact condition when not in use.

In Figures 1 and 2 I have illustrated the device in its used position and it will be noted that the bight 5 engages the jar under the lower flange of the cap while the bight 5 engages the cap above the lower flange of the cap. In this way it is possible to use the device both as a carrier and as a wrench or the like for removing the cap from the jar.

It is thought that the construction, manipulation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is:

A device of the class described comprising a pair of members and a bolt, the members being each formed of a single strand of resilient material bent to provide an outwardly bowed bight which at its ends merges into arms, the arms of each member being disposed in substantial parallel coextensive relationship and having convolutes adjacent the bight forming eyes to receive the bolt and merging at their other ends into inwardly directed extensions which in turn merge into aligned trunnions, said trunnions extending to ward each other and each trunnion extending at substantially right angles from the inwardly directed extension, sleeve grips on the trunnio-ns, the arms of one member being shorter than the arms of the other member whereby the grip of the shorter member will pass under the grip of the other member when the grips are brought together, one of the bights having an upward curve whereby said. one bight will pass over a portion of the bottom flange of the cap while the other bight will pass under said flange.

JOSEPH ANDRLIK.
