CLOSET.

SPECIFICATION forming part of Letters Patent No. 365,937, dated July 5, 1887.

. Application filed March 12, 1887. Serial No. 230,688. (No model.)

To all whom it may concern:

Be it known that I, JOHN PARK, of Detroit, county of Wayne, State of Michigan, have invented new and useful Improvements in ater-Closets; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists of the combination of devices and appliances hereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a sectional view of a water-closet embodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 is a separate view of the flushing-valve in section; Fig. 4:, a side elevation of the top of same.

My invention relates more particularly to the peculiar construction and relation of the ventilating-flue for ventilating both the bowl and the water-tank; also, to a peculiar construction of lift-valve mechanism, whereby it serves at the same time as an overflow and a stench-trap for said overflow; also, in apeculiar construction of the flushing-valve.

In carrying out my invention, A represents the bowl, B the water-tank, and O the exit conduit, of a watercloset. D is its lift-valve mechanism, E its float, and F its flushing valve mechanism. G is its ventilating-flue. The lift-valve mechanism consists of a rubber ring or other suitable valve,- D. This is secured to the bottom of a tube, D. At the top of the tube is a bridge, D, to which is engaged the lifting-rod D.

D is a plate or valve attached to the lower end of the rod (2. This rod passes through a suitable guide, (2', at its lower end, audits upper end passes freely into the liftingrod D. A spring, (1, upon the rod (1, rests upon the guide (1, and beneath a stationary collar, (1 on the said rod (1 This plate or valve D is preferably of soft metal, although it may be of rubber or other material, and seats snugly up against the edged, which constitutes the valveseat. This edge (I may be of brass or of any other suitable material, and I prefer to make it in the nature of a bushing, so that it may,

if desired, be made of different metal from the lift-tube D, and can be renewed if necessary.

It is apparent now that should the flushvalve or float be out of order and an excess of water flow into thetank or bowl it cannot rise higher than the top of the tube D, for it will then pass into the tube, and as soon as the column rises to a small height in the tube its weight will depress the spring (1, the valve D will open, and the excess of water will pass through below. As soon as the water has ceased to flow in the bowl or tank and the column has partly wasted from the tube D the spring (1 will act to lift the valve D and cause it to seat snugly upon its seat (I, thus preventing a backflow of stench or sewer gases and effectually securing the same with a water seal.

The flushingvalve mechanism consists of a duit, F leading by means of the flushingpassage to the rim of the bowl in the usual way.

Another compartment, F beneath, communicates freely with the water-supply pipe F Upon the under side of the dividing-partitlon is a depending edge, f, which constitutes the seat for the valve F. This valve is fastened securely to the stem f, and is preferably provided with a block of rubber, f or soft metal or other suitable material. A spring, f, beneath the valve operates in a direction to assist the ,water to seat the valve and to hold the valve-stem firmly against the float-arm until the valve finally reaches its seat. This has the effect to cause the valve to seat quietly and not with a jump, as is quite frequent. The valvestem is engaged with the float-arm by a slotand-pin connection, f, so as to admit of sufficient play to avoid any binding between the parts or upon the line of the valve-stem.

It will be observed that this valve has no packing of any kind and that its parts are exceedingly simple and accessible.

It has been customary to ventilate both the bowl and the water-tank either by separate connections with a chimney or special fine or by connecting the bowl with the tank by a passage and then connecting the tank alone with said flue. In this latter case the connection has usually been at the extreme rear of the tank and quite inaccessible in the large macase, F. A compartment, F, has an eXit-conjority of cases where the closet is set closely back against a wall. To avoid this I- connect the bowl and tank by a connecting-passage, G, and then leading off a connection from this passage, as shown at G, to the ventilating fine or chimney. This passage G is located well forward between the tank and bowl', so that no matter where the closet may be set this connection will always be readily accessible to the plumber.

What I claim is- 1. The combination, in a water-closet, ofthe bowl A, the tank B, having its lower portion in direct communication with the discharge of the bowl and joined thereto, the lift-Valve D, having the tube D provided at its upper portion with a bridge, D, and at its lower portion with a bridge, (1", the tubular lifting-rod D", connected with said bridge, a trappingvalve, D arranged at thelower end of the tube and provided with a valve-rod, (1 extending up through the said bridges into the tubular lifting-rod and movable vertically therein, and a spring, d, on the valve-rod, substantiall y as described.

2. The combination, with the water-closet bowl A and the water-tank B, communicating therewith, 'of the flushing-valve mechanism, consisting of the twocOmpartment case F F, having the valve-seat f, the valve-stem f, having the upwardly-seating valve F and extending through the top of the case, the spring f, the float E, and the pivoted float-arm earrying the float and having a pin-connection with the upper end of the valve-stem, whereby the float aids in closing the valve, substantsally as described.

In testimony whereof I sign this specification in the presence of two witnesses.

JOHN PARK.
