Patented Dec. 1, 1936 UNITE D". STAT ES CAP REMOVER 1 Morris Brin,- Chicago, Ill., assignor to Erwin -L. Millet, Chicago, 111.

Application December 11, 1933, Serial No. 701,750 Renewed April 30, 1936 4 Claims.

My invention relates to cap removers. One of the objects of my invention is to provide a cap remover for screw tops which will be easyto adjust, apply and operate.

Another object of my invention is to provide such a cap remover which will be sure in its gripping action.

A further object of my invention is to provide a cap remover which will be compact and neat in appearance.

A further object of my invention is to provide a cap remover which is made up largely of inexpensive, shaped sheet metal parts which may be easily assembled.

Further objects and advantages of my invention will be apparent from the specification and claims.

In the drawing in which my invention is illustrated,

Figure 1 is a top view of the tool in place on a screw cap;

Fig. 2 is a side elevation of the construction of Fig. 1;

Fig. 3 is a bottom plan view of the tool;

Fig. 4 is an enlarged side elevational view with parts in section; and

Fig. 5 is an enlarged detail view showing one of the jaws.

Referring to the drawing in detail, the construction shown therein comprises a screw top I for a jar 2 or the like, an operating lever 3 having a portion extending across the top of the screw top, a pair of jaws 4 and 5 mounted on the operating lever 3 on opposite sides of the screw top I for gripping engagement therewith, and a small cam lever 6 pivotally mounted on the operating lever 3 for eiiecting movement of the jaw 5 with respect to the operating lever to force the jaws into gripping relation with respect to the screw top.

Each of the jaws is provided with an arcuate toothed flange portion 6 for engaging the screw top circumferentially. Each jaw also is provided with an opening through which the operating lever extends. The left hand jaw 5 is limited in its sliding movement on the operating lever by a downwardly-pressed portion 1 of the operating lever which prevents this jaw from getting very far away from the cam lever B. The other jaw 4 has a considerable range of sliding movement on the operating handle to enable the tool to accommodate jar tops of different diameters. As the circumferentially-toothed flange Ii of the jaw 4 which engages the screw top is considerably offset with respect to the operating lever 3, the

law ,4 will. cant as shown, in Fig. 4 and the edges of the slot or opening in the jaw through which the operating handle extendswill bind against the operating handle to prevent sliding movement of this jaw on the operating lever when the other jaw 5 is forced into gripping engagement, with the screw top by means of the cam lever 6.

The operating handle is strengthened by the longitudinalembossed portion 8 which alsoserves to keep the slidable jaw from slipping offthe end of thellever.

As indicated in Fig. 5, when the lever is turned to rotate the screw top, the resisting action of the screw top on the toothed arcuate flange 6 will cause a canting or tipping action of the jaw with respect to the lever which extends through the opening of the jaw so that the edges of this opening will bind against the edges of the operating handle to prevent any possibility of slipping on the jaw on the operating lever and to cause the jaw to grip the top I firmly.

The right hand jaw is provided with side flanges 9 to strengthen it to resist bending action. Practically all of the parts are made of stamped sheet metal so that the tool can be made very economically.

In use, the right hand jaw 4 is slipped back sufliciently to enable the jaws to receive the screw top between them and the clamping cam lever B is shifted to the dotted-line position shown in Fig. 3. The left hand jaw 5 is then positioned against the side of the screw cap I and the right hand jaw 4 is slid along the operating lever until both jaws are in engagement with the screw cap. The cam lever B is then moved to the fullline position shown in Fig. 3, causing the screw cap to be tightly gripped between the arcuate toothed gripping portions 6 of the jaws. The operating lever is then turned to rotate the cap with respect to the container.

Due to the binding action of the jaw 4 on the handle 3 referred to above, there is no danger of this jaw slipping along the handle 3 when force is applied to the handle.

It will be seen that the construction is such that the jaws may be easily adjusted for different sizes of caps and. that the jaws may be easily and quickly clamped against the edges of the cap.

Further modifications will be apparent to those skilled in the art and. it is desired, therefore, that my invention be limited only by the prior art and the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A tool for removing screw tops comprising an operating lever having a handle portion and a portion extending across the screw top, jaws mounted on said lever on opposite sides of the screw top, one of said jaws being adjacent that portion of the lever remote from the handle portion and the other jaw being slidable on an intermediate portion of the lever for a considerable distance ior effecting major adjustment of the jaws to bring them into proximity to the screw top, and means for effecting a powerful short final gripping movement to that one of the jaws remote from the handle portion.

2. A tool for removing screw tops comprising a lever having a handle portion and a portion extending across the screw top, and jaws mounted on said lever on opposite sides of the screw top for gripping the top therebetween, one of said jaws having an opening through which said lever extends loosely and being slidable on said lever, the loose fit being such as to enable a slight canting movement of the jaw on the lever, both in a vertical plane and a horizontal plane, whereby the jaw Will grip the handle to hold it against longitudinal movement when pressure is applied and whereby the jaw will cant slightly to grip the screw top when the lever is rotated.

3. A tool for removing screw tops comprising a lever having a handle portion and a portion extending across the screw top, and jaws mounted on said lever on opposite sides of the screw top for gripping the top therebetween, one of said jaws having an opening through which said lever extends loosely and being slidable on said lever, the loose fit being such as to enable a slight canting movement of the jaw on the lever, both in a vertical plane and a horizontal plane, whereby the jaw will grip the handle to hold it against longitudinal movement when pressure is applied and whereby the jaw will cant slightly to grip the screw top when the lever is rotated, said lever being of fiat sheet material having an embossed portion to limit the movement of the jaw on the lever.

4. A tool for removing screw tops comprising a lever having a handle portion and a portion extending across the screw top, and jaws mounted on said lever on opposite sides of the screw top for gripping the top therebetween, one of said jaws having an opening through which said lever extends loosely and being slidable on said lever, the loose fit being such as to enable a slight canting movement of the jaw on the lever, both in a vertical plane and a horizontal plane, whereby the jaw will grip the handle to hold it against longitudinal movement when pressure is applied and whereby the jaw will cant slightly to grip the screw top whenthe lever is rotated, said lever being of fiat sheet material having an embossed portion to limit the movement of the jaw on the lever, said jaw having an extended arcuate portion for engaging the screw top.
