JAR OPENER Filed Feb. 28, 1951 VENTOR s I ATTORNEY Patented Jan. 10, 1933 UNITED STATES PATENT OFFICE The object of this invention is to provide an improved means for removing the cover of a fruit jar, assuming that the cover of the jar fits over the neck of the jarthe device being adapted for mounting in a stationary position, so that the jar may be turned by hand after the cover engages the opening device, and the slipping of the jar, or false movement of the implement will be avoided.

A further object is to provide in one form an implement or member fixed in a stationary position and having segmental gripping means thereon, and an element pivoted to the member first named and also having segmental means thereon, the two elements being complementary and cooperative in their action on the cap when the jar is rotated in a. left hand direction incident to the opening movement.

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

In the drawing forming part of the appli- I, cation:

Figure 1 is a view showing the device inedge elevation, the upper stationary element being dotted, and a fragmentary portion of a jar from which the cap is to be removed is also dotted.

Figure 2 is a bottom plan view of the structure appearing in full lines in Figure 1.

Figure 3 is a section on line 33 of F igure 2.

Figure 4: is a bottom plan view showing a modification in which two segmental elements are movable angularly about an axis ofiset from each other.

Figure 5 is a section on line 5-5 of Figure 4.

The jar is designated 10 and the threaded neck portion is shown at 11. The jar opening device includes a plate member 12 having apertures 13 and 14: therein permitting it to be secured in a stationary position and prefw erably to. the under side of the sink drain board or the like, whereby the jar, in upright position will be held in the position of Flgure 1 and applied as shown with reference to the stationary element of the opening devices.

Element 12 is provided with a downwardly turnedsegmental flange 15, and the latter has tooth llke members 16 on the inner side thereof. Any suitable construction may be employed in this connection.

A pivoted element includes the plate member 18, the latter being secured by means of pivot 19 to element 12, and member 18 is vprovided with the segmental flange 20 having tooth like portions 21 on its inner concave surface. The flanges of the stationary and pivoted members are complementary, with reference to the curvature, and the opposite sides of a jar cap are gripped when the jar is given a movement toward the left producing a slight angular movement of pivoted member 18, incident to the gripping action. This result is produced because of the position of the pivot 19 with reference to the approximate center of the opening between the segmental jaws.

A modified form of the device is illustrated in Figures 4 and 5, and a single plate 25 which may be of rectangular configuration is considered to be in a stationary position, apertures for the application of screws being shown at 26 and 27. The gripping elements may be considered as jaws and each includes a se ental flanged member, the gripping portions of which are designated 28 and 28. These members are mounted for relative angular movement, and the pivots 29, 29 are eccentric with reference to the approximate center of the opening between the jaws comprising the segmental elements.

The jar is introduced between the jaws, in substantially the manner before indicated and a left hand turn produces a slight angular, movement between the jaws pivoted oficenter, and the top being effectually held, the rota- 95 tion of the jar will, of course, result in the loosening of the cap.

Whatis claimed is:

A device of the class described, com rising an eccentri'cally pivoted plate member aving so ental means thereon adapted to grip one si e of a. jar top, and another plate member having segmental means thereon complementary to the first named means and piv- 5 oted for eccentric movement with respect thereto, the pivot points for the plates being oppositely located with reference to a. center from which the curves represented by the complementary segmental means are struck.

In testimony whereof I afiix my si FRANK P. S

ature.
