' MEANS FOR SEALING vEssELs.

SPECIFICATION forming part of Letters Patent No. 746,330, dated December 8, 1903.

Application filed July 3,1903. Serial No. 164,202. (No model.) I

To all whom it may concern:

Be it known that 1, JAMES MILNOR HIoKs,

a citizen of the United States, residing at Summit,county of Union,State of New Jersey, have invented certain new anduseful Improvements in Means for Sealing Vessels, of-

of cap for sealing the vessel-mouth by means.

of a stopper inserted into the vessel-mouth through an opening central of its upper depressed surface, said stopper being forced outward against the under side of the cap by means of the pressure of the contents of the vessel, both gaseousand fluid, or either,.the

said cap being shown with the usual screwfastening.

The object of my present invention is to attach the sealing-cap to the vesselin a simpler and more convenient manner and more cheaply. My means of securing the cap upon the vessel, as hereinafter specified, is rendered efiicient and possible from the fact that no tightening of the cap upon the vessel mouth and stopper is resorted to previous to charging the vessel, itbeing merely requisite that the cap be placed upon the vessel-mouth and held there against outward strain from within the vessel after charginga decided reversal of the old and usual method. By the old methods the pressure of the fluids outward from within the vessel tends to loosen the sealing, and the gases above the fluid often escape, leaving only the gases within the fluid remaining, and thatonly partially. Itthus becomes necessary for the one who fills the vessel to charge the contents as highly as possible and to have a surplus charge in the vessel, especially when prepared for use in hot countries. On the contrary, by my invention. the greater the pressure in the vessel the tighter the sealing will be, and the grip of the cap on the neck of the vessel will be tighter,

and no gas or fluid will escape. To open the vessel, 2. simpleturning of the cap circumferentially, so that the ears or indents on the cap match the out-outsin the rim, is all that is needed, and the pressure forces the, cap OE and the stopperout.

In order that those. skilled in the art to which my invention appertains may understand, construct, and use my invention, Iwill proceed to describe it, referring to the accompanying drawings, in which- Figure l is a central longitudinal section of my invention, showing the cap in place on the vessel-neck previous to inserting the stopper and the corkstopper in place ready to be pressed through the depressed opening in the cap by a plunger used in bottling-machines. Fig. 2 is a similar view of the stopper in place 'after being forced into theneck of the vessel through the openingin the cap and beneath .the depression. Fig. 3 is atop view showing the cap on the vessel. Fig. 4 is a top View of the vessel, the cap being removed to show the cut-outs in the rim or bead on the outside of the vessel-neck near its top. Fig. 5 is a view of the cap from its under side, showing the cars which take under the rim on the neck.

A is the body of the vessel.

B is a bead or rim near the top of the neck.

0 is a cap having a central hole E in its upper surface; s

D is a tapering depression of the upper surface of the cap 0, surrounding the opening or hole E.

b b b are cut-outs or blank spaces-in rim B.

a. is an outer flange to cap 0, which tends downward about bead or rim B when on the vessel.

0 represents ears or indents bent inward in outer flange a and are spaced in said flange a to passthrough cut-outs or blanks b b b when placing the cap 0 on the vessel and are then caused to take under rim B by a slight circumferential turning of the cap.

F is the cork stopper.

. G is the plunger of a bottling-machine.

The cap is removed by turning the ears 0 c cto the cut-outs or blanks b b b to release its hold on the vessel. The gaseous pressure then forces the cap ofi and the stopper out,

which opens the vessel.

Having now fully described my invention and the manner in which I have embodied it, what I claim as new and as my invention, and desire to secure by Letters Patent, is

1. In a means for sealing vessels, the combination consisting of a vessel provided with a neck; a rim above said neck at its top; vertical cut-outs in said rim; a cap having an outer downwardly-tending flange provided with ears bent inwardly, constructed and arranged to pass through said cut-outs, and by turning the cap circumferentially to take under the said rim on the vessel-neck and to retain said cap upon the vessel mouth; a stopper located beneath said cap whereby the vessel is sealed by the pressure from within the vessel, substantially in themanner and for the purposes hereinbefore specified.

2. In a means for sealing vessels by the pressure from the contents of the vessel, the

combination consisting of the vessel provided with a neck; an exterior rim near the top of said neck; a cap constructed to engage with said rim to secure it upon the vessel and provided with a central opening in its top surface; a stopper located beneath said cap, said cap being free from any strain upon the vessel, until the pressure from Within the vessel applies a strain through the medium of the stopper, in sealing the vessel, substantially as specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 8th day of May, 1903.

JAMES MILNOR HICKS.
