APPLIANCE von on covnas.

PatentedDec. 5, 1916.

Application led September 14, 1914, Serial No. 861,608. ltenevged Hay 8, 1916. Serial No. 96,248.

To all 'whom t may concern Be it known that I, CHARLES R. KEERAN, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Im rovements in Ap liances for Receptacle aps 0r Covers, o which the following is a specification.

The present invention relates tovan appliance adapted particularly for use in conf its future use;

The invention further consists in the features of construction and combinations of parts hereinafter'. described and claimed.

In the drawing: Figure' 1 is an elevation showing the upper part of a receptacle and threaded cap thereon, with the appliance of the present invention in operative position; Fi 2 is a vertical section on a somewhat en arged scale, showing a similar cap with the appliance of the present invention in operative position; and Fig. 3 is a plan view of a similar cap with the appliance of the present invention in operative position.

In the art to which the present invention relates, difficulty has been experienced in screwing' metal caps upon receptacles with the degree of tightness necessary to secure a perfect seal, due largely -to inability to get a -Satisfactory hold on the cap. This'is true even when the cap is knurled as shown. The same difficulty is also encountered after the jar has been sealed, when it is desired to -remove the cap.

It is the primary object of the present invention to provide an eiiicient means fortightenin and loosenin receptacle caps, which wi l not cause mutllation during the ti 'htening or loosenin operations, \and w ich further willaor to the operator a firm hold and indreased leverage.

Referring now to the drawing, and particularly to Fig. 1, the device is shown in connection with a receptacle 4 which may be of any 'suitable style and size, the receptacle v being provided 'at its upper end with the ordinary neck 5 formed with exterior threads. Upon this neck is threaded a metal cap 6 having interior threads at its lower end meshing with the exterior threads of the neck. The upper portion of the capis nnthreaded, and 1n the construction shown 1s of corrugated or undulating formation producing a ribbed surface 7.

The ap liance ofv the present invention consists o a relatively shallow cup-shaped member 8 having undulations or corrugations 9 on the depending ortion 10 thereof. These corrugations or un ulations upon the cup-Shaped member correspond to the corrugations or undulations 7 on lthe upper portion of the ca 6. The appliance 1s further provided wit a suitable hand piece 11 which may be of any convenient shape and size, and 0f any suitable material. In the construction shown, this handA piecev is attached to the cup-shaped member-8 by means of rivets 12, although the means of connection is obviously a matter of choice.

In practice, the cup-shaped member 8 of.

an operator is enabled to apply rotary pressure to the appliance through the medium of the hand piece 11. In this manner, the cap can be easily removed or aflixed as desired. It is obvious that during 'either of these operations the 'cap or cover will un dergo no mutilationor distortion, since the appliance lits snugly over the top portion of the entire cap whereby the pressure is dis tributed evenly around the entire periphery of the cap. Pressure concentrated at one or more -points on a receptacle cap of this general style would likely cause the metal to bend and become mutilated, as relatively soft and bendable material is ordinarily used in its construction.-` -By means of this simple appliancea it is manifest that acap can be readily and tightly aixed to the closure, and can be as readily removed without any danger of mutilation or distortion such as would impair its future use,

I claim:

1. An appliance for removing and aiixing jar caps, comprising an engaging member formed of a single piece of metal of cupshaped formation 4embodying a continuousl depending flange extendin in adownward direction only, said depen ing flange being formed with a corrugated surface adapted to engage With the sides of a jar cap, and a handle attached to the tcp portion of said engaging member, substantially as described.

2. An appliance for removing and afxing jar caps, comprising a cup-shaped engaging member formed With a depending flange therearound, the inner side of the flange being corrugated to engage and interlock with a similarly corrugated exterior surface on the jar cap, and a handle attached to the, engaging member for manipulating the Same,

hsubstantially as described.

3. An appliance for removing and afiXing jar caps, comprising an engaging member formed with a depending ange therearound, the inner side of the ilange being corrugated. to engage and interlock With a similarly corrugated exterior surface on the jar cap, and a handle attached to the engaging member for manipulating the same, substantially as described.

4:. An appliance for removing and alixing circular j ar caps having corrugations on thev periphery thereof, comprising a member formed to engage with the cap at substantially every point in its periphery, the engaging surfaces of the member being substantially equidistant from a central point therein, and having corrugations to engage and interlock With the corrugations on the cap, and a handle attached to the engaging member for manipulating the same, substantially as described.
