WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 404,393, dated June 4, 1889.

Application filed March 6, 1889. Serial No. 302,107. (No model.)

To all whom it may concern:

Be it known that I, ALBERT ELMENDORF, a citizen of the United States, and a resident of New London, county of New London, and State of Connecticut, have invented a new and useful Improvement in \Vater- Closets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to an improvement upon the flushing and bowl-ventilating arrangement upon which Letters Patent were granted to me on the 3d day of July, 1888, No. 385,409, in which a flushing stand-pipe was employed in connection with a ventilating-ex tension of said pipe and a ventilating-pipe connecting the bowl. and said extension for drawing off the gases and foul air from the bowl in the process of flushing thelatter; and my present improvement consists in connecting the valve through which the flushing of the bowl is eifected with a valve in the ventilating-extension of the stand-pipe at a point above the connection of the bowl-ventilating pipe with said extension in such manner that when the valve for flushing the bowl is opened for that purpose the ventilating-extension of the stand-pipe will be closed, thereby compelling the air and gases for supplying the vacuum in the stand-pipe caused by the fallin get the column of water therein to be drawn from the bowl through the ventilatin g-connection of'the bowl with the stand-pipe.

It further consists in a novel construction of the valve connecting the supply-pipe and the bowl with the flushing stand-pipe and in certain details of arrangement of the parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 tilating-extension of the stand-pipe and its valve.

A indicates the bowl and A the casing and seat therefor, which parts may be of any usual or preferred form.

1) indicates the flushing stand-pipe; C and C, a ventilating-extension thereof, the latter extending to or connecting with a flue and thence with the open air; D, a valve-chamber connecting at its upper end through a pipe at with the lower end of the stand-pipe and at its lower end with the water-supply pipe a. The stand-pipe B is similar to that described in the Letters Patent above referred to, and is provided at its upper end with a float-valve for closing said end when said stand-pipe is full, as described in said patent. The construction of the supply and flushing valve is shown in Fig. 3.

The valve-chamber D consists of a short section of pipeenlarged to accommodate th e valve E, and provided with an inner tube D extending upward from its lower end and terminating in a perforated diaphragm D having annular ribs (Z d on its upper face forming the valve-seat. The valve is recessed 011 its lower face to receive a packing-ring c, which rests, in the normal position of the valve, on the annular ribs (1 and cl, covering the space and the openings (1 between them, said openings communicating with the space around the inner tube D and connecting said space with the chamber above the diaphragm D The valve has a central ring at e to receive the valvestem E, which extends down through the tube D and through central guiding perforations in diaphragmsf and f therein, and is provided with a conical valve F, of rubber or other suitable material, secured to its lower threaded end by a nut E said valve F serving, when the valve E and stem E are raised, to close the lower end of the tube D and prevent the water from the supply-pipe from rising therein.

The valve E has perforations or slots 6 around the ring 6, connecting the tube D with the space in the valve-chamber above the valve E, and the diaphragms f f have similar perforations f around their central guidingnrings, which permit the passage of the water up around the valve-stein and through the valve E into the valve chamber, whence it passes into the stand-pipe connected therewith, preferably through a short pipe (0, as stated. The valve F is inclosed in a chamber F in the upper enlarged end of a short coupling-section of pipe a which screws on the lower end of the valve-chamber section D, as shown, and has the supply-pipe a secured to its lower end in any usual manner.

a indicates the short section of pipe which connects the valve-chamber D with the standpipe 13, and which is preferably secured to the valve-section of pipe by means of a threaded nut or collar 3 engaging an annular flange on the pipe a and the screw-threaded upper end of the valve-chamber section 1), as shown; but any suitable form of coupling may be employed for uniting the parts.

D is the flushing lateral branch or tube, which at its inner end connects with the portion of the valve-chamber around the tube D and below the va1ve-seat or diaphragm, and which at its outer end is connected with the bowl A in any usual manner for flushing it.

It will be seen. from the foregoing description that when the valve E is seated on the annular ribs (Z and d the water from the supply-pipe a can pass up freely around the valvestem E and through the valve E for filling the standpipe, and that no water can escape through the openings between said ribs into the branch D for flushing the bowl, and that when the valve E is raised it lifts the valve F through the stem E, thereby closing the tube I) and cutting off the water-supply, while at the same time the water above the diaphragm E and in the stand-pipe can escape freely bet-ween the ribs 6 and 6 into the space below the diaphragm D' and thence through the pipe D into the bowl for flushing the latter.

The upper end of the stem E, projecting through the valve E, is screw-threaded to engage a threaded perforation in the lower end or cross-bar of a loop or open link 1, which is provided on the inner face of one of its upright bars with teeth g, forming a rack, with which the teeth h of a pinion or segment h on a rock-shaft ll engage for operating the valves E and F. The shaft H is journaled in suitable bearings in the side walls of the valve section or chamber D, and one end thereof, projecting through its supporting-wall, has a lever 7L2 fast upon it, made, preferably, in bellcrank form, and to one arm of which a spring 4 has one end connected, the other end of said spring being connected to a suitable fixed sup port, with the spring arranged to exert its tension to close the valve E and open the valve F.

0 indicates a section of the ventilating-extension of the stand-pipe 13, connected to the upper end of the latter, (just above the floatvalve referred to,) and to which the upper end of the bowl-ventilating pipe I) is connected, the lower end of said pipe connecting with the bowl for drawing off the foul air and gases in a manner described in the former patent referred to.

At a point above the connection of the pipe Z) therewith the section 0 (see Fig. 4) is provided with an inclined partition or diapliiragm J, having a large central opening J, and underneath said diaphragm is located a valve K, connected through a stem 7a with a rockshaft L, journaled in bearings in the side wall of said section, near the upper end of the diaphragm, and having a bell'crank lever L fast on its projecting end. The lower face of the diaphragm J has a suitable valve-seat formed in or upon it, and the upper side of the valve is provided with a packing-disk K, of any suitable material, snugly fitting the valve seat for closing the opening J. One arm of the lever L connected by a cord or chain on with the lever 7L2, and has a pull cord or.

chain on connected to its other arm, the arran gement being such that when the cord m is pulled, depressing the arm Z of the lever L, the shaft L will be rocked to close the valve K, and the arm Z, to which the chain m is attached, will be raised, lifting the valves E and F, through the connections described, for flu shing the bowl and cutting off the water-supply. By this operation the supply of air from the ventilating-extension C will be cut off and the supply of air necessary to replace the falling column of waterwill be drawn through the bowl-ventilatii1g pipe I) from the bowl, thereby drawing elf the foul air and gases from the latter. \Vhen the pull cord orchain m is released, the spring t' operates to close the valve E and open the valve F, and at the same time, through the cord m and lever L, to open the valve K, so that as the stand-pipe fills, the air and gases above the water in the stand-pipe are forced up through the ventilatingextension 0, and thence, through a suitable fine or otherwise, out into the open air.

The relative size of the ventilating-extension of the stand-pipe and the ventilatingpipe connecting the bowl with said extension, and the natural tendency of the foul air and gases to rise, causes said air and gases to flow out naturally through the freer upward vent allorded by the ventilating-extension, when the valve in the latter is open, and enables me to dispense with the valve in the bowlventilating pipe described in my former patent above referred to. A further advantage in dispensing with said valve and leavingthe bowl-ventilating pipe open lies in. the fact that if, from any cause, there should be leakage in the valve for closing the stand-pipe when the latter is filled, the water so escaping from the stand-pipe will flow down through the bowlventilating pipe to the bowl and waste-pipe, and so all danger of flooding or damage from such leakage is effectually avoided.

N indicates a bracket for the attaclunent ot' the stand-pipe to the wall or other support,

and P a man-hole in the section 0 for giving access to the valve K for repairs or other purpose.

Having now described my invention, I claim as new 1. The combination, with the bowl and its flushing stand-pipe, of the ventilating-extension of said pipe, the ventilating-pipe conn ecting said bowl and ventilating-extension, the flushing-valve, and the valve in the ventilating-extension connected to the flushing-valve to be operated simultaneously therewith,substantially as described.

2. The combination, with the stand-pipe and bowl and the flushing-valve connecting said pipe and bowl, of the ventilating-extension of said stand-pipe provided with a valve connected to said fiushing-valve, and aventilating-pipe connecting said bowl with the ventilating-extension of said stand-pipe, substantially as described.

3. The combination,with the bowl and stan dpipe, of the interposed valve-chamber having the perforated diaphragm D and inner tube D, and the connected valves E and F, arranged and operating substantially as described.

i. The combination, with the bowl A and its flushing stand-pipe B, of the interposed valve-chamber or section of the stand-pipe having the perforated diaphragm and the lateral flushing-pipe D below said diaphragm, the lift-valve E, the water-supply valve F, connected to said lift-valve to operate as described, and the rock-shaft connected to said valves for operating them, substantially as described.

5. The con1bination,with the bowl in a flushing arrangement for water-closets, of the flushing-valve E, the ventilating extension or pipe 0 0', provided with a valve K, the ventilating-pipe 1), connecting the bowl with the ventilating-extension pipe, and connections, substantially as described, for simultaneously operating the valves E and K, for the purpose specified.

In testimony whereof I have hereunto set my hand this 4th day of March, A. D. 1889.

CHARLES PRENTI's, S. A. GARDNER.
