7 PIVOTED LEVER JAR CAP REMOVER Filed 'July 19, 1946 HIIHIIIIIHIIllllllllllllll I N VEN TOR.

wwz ad I ATTEI RN EYS Patented Apr. 10, 1951 UNITED STATES PATENT OFFICE 1 Claim. 1 This invention relates to improvements in jar cap removers, and more particularly to a pivoted lever jar cap remover.

An object of v this invention is to provide a jar cap remover which is adjustable to fit various sizes of jar caps.

Another object of the invention is to provide a jar cap remover which is comprised of cap engaging levers that are pivoted for movement in two parallel planes for the accommodation of jar caps of various sizes.

A further object of the invention is to provide a jar cap remover that is simple in construction and operation, inexpensive to manufacture and durable and efficient in performing the tasks for which it has been designed.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing in which:

Figure 1 is a plan view of an embodiment of the invention, in operating position, to engage jar tops of large dimensions;

Figure 2 is a plan view of the same, in operating position to engage jar tops of small dimensions;

Figure 3 is a fragmentary detailed elevational view, showing the manner in which a crown top may be removed from a bottle;

Figure 4 is an elevational edge view of the device and Figure 5 is a sectional view on the line 55 of Figure 1.

Referring more in detail to the drawing, the jar cap remover forming an embodiment of the invention is generally designated by the reference numeral II]. The jar cap remover I0 comprises a pair of curved jaws H and I2 respectively, which have handles I4 and I3 respectively formed integrally therewith. The jaws will, when placed end to end, form a full circle. At each end of each jaw, where it is formed integral with its respective handle, and the handles are placed in overlapping relation to each other, there is provided a pivot l5. This pivot permits the jaws and their respective handles to be rotated with relation to each other in two parallel contacting planes.

The inner face edge of the jaw H is provided with teeth I6 which cover the entire inner face edge thereof. The inner face edge of the jaw I2 is provided with similar teeth I! for the same distance. The jaw l2 comprises an are which is approximately one-third of the abovementioned full circle formed by the jaws. Therefore, to form a complete circle, the jaw ll comprises an are which is of approximately twothirds the same circle.

On the inner face edge of the handle I4, there are prvoided teeth [8, which extend inwardly from the inner face edge to form an are which is of a smaller degree than the arc of the jaw 12.

It will be noticed from Figure 1, which is used for large jar caps, and Figure 2, which is used for small jar caps, that the teeth are never presented outwardly to be engaged when the opener is manipulated to open a jar cap of either a small or large size.

The jaws and their respective handles are pivoted in relation to each other, to effect the adjustment of the jaws for the removal of the jar caps.

The jaw H is provided with an opening l8, whereby the jar cap remover may be suspended from a suitable support.

In Figure 3, the jaws are used to remove acrown cap l9 from a bottle 20, and to effect this operation, the jaw H is provided with a notch 2| which engages the top of the crown cap. The jaw 12, at its extreme end, is provided with a tooth 22 which engages under the crown cap, as shown by a notch 23, inwardly of the tooth 22, which permits the jaw to fit over the bulges or ribs 24 usually found on bottles of this type.

There has thus been provided a jar cap remover that is adjustable to fit nearly all sizes of jar caps. By applying the jaws to the cap, and squeezing the handles, the cap may be loosened or tightened as desired. The proportion of the relative length of the jaws permits full encirclement of the jaws with an equal amount of leverage provided for either small or large caps.

The device will accomplish the objects set forth, and it is believed that, from the foregoing description, the operation and construction of the device will be apparent to those skilled in the art.

It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided theyfall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be obtained by Letters Patent is:

In a jar cap remover having a pair of curved jaws in parallel planes, with one of said jaws being of greater length than the other of said jaws, a handle formed integral with and in the same plane as each jaw and pivoted together in overlapping relation to each other and the inner edges of said jaws having tooth formations thereon, the improvement comprising curved inner gripping teeth on the inner edge of the handle formed on the larger jaw so that when the handles are pivoted the gripping teeth on the other of said jaws will coast with the teeth on 10 the inner edge of the handle to engage a jar cap therebetween.
