Specification of Letters Patent.
Patented Oct. 3, 1911.
Application filed March 10, 1910. Serial No. 548,331.
To all whom it may concern:
Be it known that I, FRANK W. Bnrrrs, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Jar Openers, of which the following is a specification.
This invention relates to kitchen appliances, and more particularly for bottles and jars and devices adapted to use in removing screw tops from jars and like receptacles.
An object of the invention is to provide a jar and cap so constructed that they may. be readily engaged for relative rotation.
Another object of the invention is to provide such a device which will be extremely eflicient in operation and which may be manufactured at a low cost.
An important object is to provide such a device which may be made from one piece of wire.
Another object is to provide such a device formed of wire which will be adjustable in a novel manner for engagement with jars of various sizes.
Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.
In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a plan view of the opener in inoperative position, Fig. 2 is a similar view showing the device engaged with a ar, Fig. 3 is a fragmentary detail of the formation of the handle and fulcrum arms, Figs. 1 and 5 are detail views respectively of the can and cap, Fig. 6 illustrates a modification in the handle construction of the device, and Fig. 7 illustrates a modified form of loop.
Referring to the drawings, there is shown a can 10 having a longitudinally extending rib 11 formed centrally thereof and stopping short of the can ends, and having a cap 12 screwed thereon provided with a laterally projecting lug 14: as shown. Engaged respectively with the can and cap, there are two of the implements forming a part of the present application.
The device comprises a handle portion 15 and a loop portion 16 having a notch 17 the sides of which extend sharply at an angle with the adjacent portion of the loop forming opposed shoulders adapted to engage firmly against either side of the lug in the cap or the rib of the can.
As shown, the device is formed from one portion of wire, one extreme end portion of which is crimped in the plane serpentine form shown at 18, for a purpose to be sub sequently indicated. The adjacent inner portion of the wire is bent in curved form to provide the loop, and centrally thereof the notch 17 is formed by bending the wire outwardly in U-shape. A spaced distance inwardly of the notch the wire is bent outwardly at an angle, and extended the length of the handle, from which point it is bent inwardly upon itself to the base of the handle where it turns laterally in alinenient with the adjacent inner portion of the loop, and extended a short distance from which point it is again turned inwardly upon itself forming a fulcrum arm 20 and then is carried to the handle around which it is wrapped and extended to the outer end thereof. Spaced a short distance from the handle, the wire at one side of the fulcrum arm 20 is extended laterally at a sharp angle and twisted, as shown at 21 to form a dog arm arranged for engagement in the serrations 18 at any point, thus permitting the size of the loop to change to accommodate jars of different sizes.
In use, the loop portion is engaged around the can with the notch disposed over the rib of the can or lug of the cap, the serpentine portion pressed firmly against the can and the handle swung inwardly thereagainst and thedog arm adjusted in the proper convolution of the portion 18 to hold the device securely upon a can. If the cap is unusually difficult to remove, two of the implements may be used as will be readily appreciated, one being applied to the body of the can and the other to the top. After their adjustment as above described, the handle portion is pressed laterally in the direction of the fulcrum arm 20, and the notch 17 holding the device against slipping, the can and closure may readily be rotated.
The function of the portion 18 is simply to hold the notch against outward slipping thereof, and it will be seen that no great degree of tensile strain is applied thereto, so that any resilience of the wire due to this formation Would not interfere with the proper gripping action of the device.
s shown and described, it will be seen that the device is readily adapted to be manufactured at a very low cost and combines a maximum strength with a minimum amount of Weight and material.
In Fig. 7 there is illustrated a simple form of the opener which is of standard size for the engagement with fruit jar caps, and in this form the adjustable feature is eliminated, resulting in its simplification and lower cost.
The can and cap illustrated may be formed of any suitable material, the illustrations representing a glass jar having a metal cap. The jar may be blown in the usual manner, and the cap may be stamped integrally from sheet material as is customary in such constructions.
What is claimed is:
A device of the class described formed from Wire and comprising a split loop member having its end portion bent tortuously in a plane common with that of the loop, said loop having a notch formed centrally thereof and adapted for engagement With a jar or the like having a peripheral lug With the- FRANK W. BETTIS.
