JOSEPH DE MARS, OF ALBUQUERQUE, TERRITORY OF NEW MEXICO, ASSIGNOR OF ONE-FOURTH TO FREDERICK E. MCKINLEY, OF SAME PLACE BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 485,093, dated October 25, 1892.

Application filed March 31, 1891.

To all whom it may concern:

Be it known that I, JOSEPH DE MARS, of Albuquerque, in the county of Bernalillo, Territory of New Mexico, have invented a new and useful Improvement in Bottle-Stoppers, of which the following is a specification.

My invention relates to that form of bottlestopper in which a rubber disk or plug is drawn up against the neck of the bottle from the inside and is retained thereagainst by the pressure of the gas within.

My invention consists in the special con struction of the stopper, whereby it is retained in its closed position independent of the pressure of the gas, as hereinafter fully described.

Figurel is a sectional view of a bottle-neck with the stopper in its closed position, this form of stopper being designed for soda-water. Fig. 2 is a similar view with the stopper thrust down to open the bottle. Fig. 3 is a view similar to Fig. 2, but with a form of stopper designed for beer. Fig. 4 is a perspective view of the springshank of the stopper.

A represents the soft-rubber disk adapted to close against the edges of the neck of the bottle. This disk is retained between a metal button B below and another smaller one C above. These buttons are fastened together and attached to a spring-shank D D, which passes up the neck of the bottle and projects outside of the same. This spring-shank consists of a single piece of steel wire bent into the shape shown in Fig. 4 and tinned to prevent rusting. It has two divergent loops D and D, respectively, of which D is longer than D and is bent inwardly at its end. The free ends a a are soldered to the button O, and the middle bend or small loop b passes through the bottom button B and affords a hold for a hooked instrument to seize the stopper when it is to be entirely Withdrawn from the bottle, for which purpose the bottlestopper is turned around within the bottle, so that the elastic disk A can bend over the Serial No. 387,092. (No model.)

relatively small button O to a size small enough to pass through the neck. With this construction the two spring-shanks D D of the stopper, springing divergently away from each other, bear against the mouth of the bottle and draw the stopper up to close contact with the neck inside the bottle.

I am aware of the patent to Allison, N 0. 224,122, dated February 3, 1880, in which the spring-shanks are made of two simple pieces of wire. My spring-shanks are compound in character, being made with four sections or legs, but all of one piece of wire. These four sections serve the purpose of keeping the bottle-stopper better centralized in the neck of the bottle and aiford with a small wire a sufficient spring tension to cause the expansion of the shanks to make a practical self-closing stopper. The friction of the shanks on the bottlemouth also being distributed upon four points, it does not chip or fracture the edge of the mouth as a single piece of stout wire would.

Having thus described my invention, what I claim as new isl. The bottle-stopper consisting of the elastic disk and retaining-buttons having upwardly-projecting divergent shanks bent to form loops at the upper ends with four sections or legs disposed, as described, to bear equally against the inner periphery of the bottlemouth, substantially as shown and described.

2. The bottle-stopper consisting of the clastic disk and retaining-buttons having upwardly-projecting divergent shanks bent to form loops at the upper end with four sections or legs disposed, as described, to bear equally against the inner periphery of the bottle-mouth and terminating at the lower end in loop I) and free ends a a, the whole being made of one piece of spring-wire, substantially as described.

JOSEPH DE MARS.
