JOHN S. GILBERT, OFNEW YORK, N. Y.

DISCHARGE-PIPE PLUG FOR WASH-BASINS,

SPECIFICATION forming part of Letters Patent No. 258,048, dated May 1 6, 1882,

Application filed February 21, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. GILBERT, of the city, county, and State of New York, have inventeda new and useful Improvement in Dis-- charge-Pipe Plugs for Wash-Basins, of which the following is a full, clear, and exact description.

Reference is to be had to the aocompanyin g drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure l is asectional side elevation of a wash-basin to which my improvement has been applied, and Fig. 2 is a plan view of the same.

The object of tliis invention is to improve the construction of the discharge-pipe plugs for which Letters Patent No. 213,891 were granted to me April 1, 1879, in such a manner as to make the plugs automatic in their action and to prevent sewer-gas from entering rooms through the discharge-pipes of wash-basins.

The invention consists in the combination, with the hinged'plug of a wash-basin and its chain, of a float, whereby the said plug will be raised automatically when the water has risen in the basin to a fixed point, as will be hereinafter fully described.

A is an ordinary wash-basin, and B is its discharge-pipe.

O is the plug that closes the discharge-pipe B, and which is hinged at one side to the basin A.

To the free side of the plug 0 is attached the end of a chain, D, the other end of which is attached to the edge of the basin A, or to some other suitable support, so that the chain D can be readily grasped and operated to allowthe water in the basin A to flow out.

E is a float of sufficient buoyancy to raise the free edge of the plug 0 and allow the water in the basin Ato flow out. The float E may be a hollow ball of rubber or other suitable material, or a solid ball of cork or other material having the necessary lightness. The float E can be attached to the chain D at such a point that it will rise to raise the plug 0 when the water has risen in the basin A to a fixed point. By this construction the basin A can never become filled and run over, so that there will be no necessity of providing the ha sin with overflow-openings and an overflowpipe, thus preventing sewer-gas from entering the room through the overflow-pipe.

To the bottom of the basin A is attached the end of a spring, F, the free end of which projects over the hinged plug 0 in such a position as to prevent the said plug from being turned back upon its hinge by pulling upon the chain D so far that it will not close automatically when the chain D is released.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- In a discharge-pipe plug for wash-basins, the combination, with the hinged plug G and its chain D, of a float-,-E, substantially'as herein shown and described, whereby the said plug will be raised automatically when the water has risen in the basin to a fixed point, as set forth.
