WATER-CLOSET.

339,480, dated April 6, 1886.

(No model.)

securely closing, when not required to be open,

drain-pipes at or near their connections with water-closet pans, wash -bowls sinks, bathtubs, or other similar fixtures.

It consists in a combination, with the discharge-pipe of such fixture, water-closet, or

wash-bowl, &c., and the connecting drain, waste-water or soil pipe, and with a plug or stopper trap valve, which with its box and seat is placed immediately below the end of said discharge-pipe and above or in the corn mencement of said soil or waste-water pipe, joining the two and forming their continuation, of an auxiliary or independent S-shaped pipe, trap-overflow arranged to connect said discharge-pipe from its upper surface just before it terminates in the trap-casing with the continuing drain or soil pipe below the site of thestopper-valve, said S,additional, and overflow pipe having also combined in its course a self-closing valve, so placed that it shall be opened by pressure of overflowing water from above, but only more tightly closed by pressure of gases rising from below, whereby, first, the contents of said watercloset, basin, or other 3 5 fixture is allowed to discharge when said stopper or plug valve is elevated by lifting upon its handle, and wash-water is at the same time and by the same movement allowed or caused to pass through; second, the stopper or plug valve, when not purposely elevated, shall remain seated to prevent an upward escape of sewer gases or soilpipe emanations, and whereby, third, when such plug or stopper valve is closed provision is made through the auxiliary and additional 8 and trapped connecting'pipe for the safe and easy escape of water which may from any imperfection of apparatus or otherwise be allowed to run into the connecting basin, sink, bath-tub, or other receptacle, and for the prevention of damage by overflow.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a partly sectional view in elevation of a water-closet bowl or basin with my invention applied.

A indicates the waste, drain, or soil pipe with which the dischargepipe B from the basin or bowl 0 of a water-closet connects, and which in itself comprises an S-trap, b, be tween such connection and the sewer or main and soil pipe with which the drain-pipe connects and is continuous.

D is a plug or stopper valve, of a plunger or any other suitable construction, arranged to close the wastepipe A at its commencement below the valve-casing, also below and beyond the termination of the discharge-pipe B, and is capable of being operated from above the watcr-closet seat by its stem and handle 0 or otherwise when it is required to open connection between the discharge-pipe B and the waste, soil, or water pipe below it. said valve to be operated automatically or at pleasure, with a substantial seal to shut out from the apartment or building in which the water-closet or other water fixtures or structures are situated sewer-gases and soil-pipe emanations. Furthermore, said stopper or plug trap valve has or may have combined with its stem and its casing, or substantially the latter, and operating above the seat of the closet, a

, screw-cap or other locking device, E, for forcibly and permanently, when required, securing its more certain and firm closure. This, as shown in the drawing, is applied as noted to the stem of the valve above the water-closet seat, where it is readily accessible, and when set by screwing it down upon a pin or collar, 8, placed low down upon the valve stem or rod in the drawing, but properly being high up on the stem and within the lock-cap E, serves to compress the valve-plug upon its seat, and retain it there indefinitely and as desired, for the purpose of preventing during such time all upward and outward escape of gases. It is to be observed that this lock is detached and not an essential feature of the trap. It is an additional and convenient means for secur ing prevention against the entrance of sewergases and soil-pipe emanations at night, or during longer periods when the water convenience is not in use, during. seasons when the house is unoccupied, and through unused fixtures, bath tubs, water closets, and washbowls in upper and unused rooms in houses otherwise occupied, wherein other, and especially water-seal traps, soon evaporate away, and thehouse andits inmates are unconsciously subjected to the entrance and bad effects of these gases. In this detached but readily applied manner this look, it will be perceived, is of great value. On releasing the look, however, said valve D may be raised at pleasure to admit of matter passing from the dischargepipe B into the waste or soil pipe A. It will be noticed, however, in such an arrangement or combination of devices that when the plug or stopper trap valve D is closed orheld closed by application of the locking device there can be no automatic discharge from the basin or other receptacle situated above through the discharge-pipe Binto the waste-pipe A. There might occasions occur by reason of some defective condition or action of the device for controlling the flow of wash-water to the watercloset basin or pan, or on account of forgetting to turn off the faucet to another fixture where this stopper-trap may be in use anddisconnected in its action from the action of the supply-faucets, that water should continue to flow into the receptacle, fill, and overflow, and thereby cause damage from such overflowing; but to prevent such retention and damage by water, and yet equally provide against the escape upward of sewer-gases and soil-pipe upper side of the valve-box 6 connection is formed with the waste-pipe A by a pipe, d. The commencement of this overflow device is madefrom the upper surface of the dischargepipe B, in order that it may not catch and become filled with solid matter passing through said pipe B; and, furthermore, so that water even should not pass through it until the discharge-pipe and basin are filled to a certain level in order to retain water in a pan, it turns and extends downward and then upward, in order to form a water-seal, and also to enter the box 6 from beneath, and thus act against and cause its valve 6 to open by upward pressure. The connecting-pipe d with the wastepipe A is given off from the upper part of the chamber formed by the valve-casing e above its valve 6', so that any pressure of gases arising in the waste-pipe A from the sewers or soil-pipes and entering the connecting-pipe d shall act upon the upper surface of the valve 6'' to keep it even more tightly closed. The valve trap or box 6, with its valve 6, is represented as a simple poppet-valve, with'its valvestem free to slide upward in a screw-cap, f, on

the top or" the chamber which holds said valve,

so that the valve 6 may readily be removed when required by taking off the screw-cap f. Thus this overflow attachment provides for an automatic and cflicient discharge and escape of running water on the one hand, while it equally, by its 3 shape and additional trap operated, as described, provides against an upward escape of injurious gases on the other.

Having thus described my iuvention, what I claim as new, and desire to secure by-Lett'ers Patent, is-

The overflou S-trap pipe G and its selfclosing valve 0', in combination withthe discharge-pipe B, the branch piped, drain-pipe A, with its plug or stopper trap valve capable of manipulation by hand, and the basin, pan, or receptacle 0, essentially as described.
