VENTILATING WATER-CLOSET.

Specification of Letters Patent.

Patented July 2, 1907.

Application led January 11,1905. Serial No. 240,579.

To all 'whom 'it may concern:

Be it known that I, CECIL HOLMES THOMPSON, a subject of the King of Great Britain, residing in the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a new and useful Improvement in a Ventilating Water-Closet, of which the following is a specification.

My invention relates to the arrangement of the combination of a series of valves, whereby in the use ofthe water closet, and the weight applied to the seat, by the user ofthe closet, will cause the water to pass through the valve casing, through the valves, and escape into a spray nozzle arranged in a vent pipe communicating with the bowl of the closet. By the escape or the egress of the water through the nozzle a suction is created, which draws all the odor from the closet, and forces the same with the spray up through the vent pipe. The water after it has lost its force from the nozzle flows back into the bowl through the vent pipe.

The device is so arranged and constructed that the spray and suction will be continued while the weight is on the seat, and after the weight is removed from the seat the water causes the different valves to close, and the different parts to return to their respective or starting positions, and the Ywater to shut ofi. Further the operating valves are arranged in combination with a small regulating valve, whereby the valves may be set to close ofi at any desiredI or pressure, so that any desired or length of time maybe given for Ventilating the closet. I may also arrange the device to operate in combination with the Hushing operation of the closet.

I attain these objects by the device as illustrated inthe accompanying drawings, in which- Figure 1 is a perspective view of a water closet bowl, with the parts of my invention in combination; Fig. 2 is a sectional elevation of the valves and connecting parts; Fig. 3 is a cross sectional view through the valves; and Fig. 4 is a detail sectional view of the nozzle and vent pipe.

Like letters refer to like parts throughout the drawings and specifications.

In the drawings I show a water closet bowl a, of the ordinary type, provided with a hinged seat b, and a lid or cover c. Extending rearward from the top plane of the bowl is an extension d, and on this extension is bolted the valve casing e. The valve casing is cast to form a pair of parallel cylinders f and g, in which work up and down a valve h and a piston i respectively. Screwed into the top oi the cylinders j" and g, are suitable caps j and 7c, provided with any ordinary packings to fit around the spindles Z and m, of the respective valve and piston h and t', which extend up through and above the top of the valve casing, and are formed integral with the pistons. Arranged in the cylinder f is a valve seat n, on which engages the valve h, and passing from the cylinder f into the cylinder g is a port o, provided with a counter bore o, in which engages a ball p. The ball is retained in the bore o, by a small spiral spring q supported and retained by a pin r, projecting from a plug s, screwed into the side of the cylinder f, opposite the port o. Passing through the bottom oi the cylinderf is an inlet t, surrounded by a screw threaded collar u by which may be coupled the feed pipe '0, through which the water is supplied to the valves.

In the upper part of the cylinder above the valve seat n, is an outlet port' w, which communicates with thespray pipe x, which terminates in a nozzle x/, and enters into the vent pipe y. The vent pipe y is coupled with an opening l in the side of the bowl, and may be carried to the roof of the house. The nozzle x/ may be of any desired shape 'or construction adaptable for the purpose specified. lThe design of the one shown in the drawings is of the simplest form, and is shown merely for description.

Extending into the web of the valve casing between the cylinders f and g, is a small regulating screw valve 2. The screw valve 2 consists of a tapered head 3, provided with a shank 4 and terminating in a thumb nut 5, which projects through and beyond the packing nut 5C The head ,3 maybe turned to regulate the amount of passage from the cylinder f to the cylinder g, through which the water passes into the cylinder g, and causes the piston i to rise.

Communicatingr with the valve 2 and engaging with the tapered head 3 is a port 6 from the cylinder f, and communicating with the valve 2, and the cylinder g is a port 7, by which the water may be regulated t0 flow from one cylinder to the other. The water enters in through the inlet tin the bottom of the cylinder f, and passes through the port 6, through the valve 2, and through the port 7 into the cylinder g, and forces the piston upwards, until its limit is checked by the valve h, engaging with the valve seat n in the cylinder f. The spindles l and m of the respective valve and piston h and i, are coupled together by a yoke 8, fastened to their upper ends, so that both valve and piston travel in uni son and simultaneously. Connected into the upper end of the cylinder g is a small vent pipe 9, by which the air or any water that may get above the piston may be drained of. The vent pipe 9 may be carried down to discharge into the iiushing pipe l0, or may be carried directly into the bowl.

Formed integral with the valve casing a, and projecting upwards from each side and terminating in an elongated head 11 is a lug 12, to which is pivoted a hinge operating plate 13. Through the head ll ofthe lug 12 are a series of bolt holes 14, by which the plate 13 may be pivoted to the lugs l2 by bolts 15, the series of bolt holes 14 are lor the purpose oi adjusting the parts for the different conditions of seats. Fastened to the back edge o the seat b is a fastening plate 16, having two upright extending lugs 17 provided with circular heads4 18,

adapted to engage with the front edge of the operating plate 13. Fastened to the top back edge of the lid or cover c, is a hinge plate 19, provided with two rearwardly extending lugs 20 terminating in circular heads 21. The lugs 20 and 17 are so arranged that they fit on either side of the front edge of the operating plate 13, and passing through the heads 18 and 2l respectively, and through a circular opening 22 in the plate 13 is a bolt 23, by which the seat and the cover will be hinged to the operating plate 13, and also hinged to the valve casing e. The plate 13 is so arranged that the under side rests on the top of the spindle m, of the piston i, and by reference to Fig. 2 of the drawings it will be noticed that when the piston is in its raised position, it keeps the back edges oi the seat and cover slightly raised from the top plane of the bowl a.

When in operation a weight is placed on the seat b, the seat is caused to lower to the horizontal, which draws the operating plate 13 downward, and presses on the top of the spindle m of the piston t'. With the downward travel of the piston il the water in the cylinder g is orced out through the port o, and by the force of the Water the ball p is forced away from the port, at the same time being kept in its re'laive position with the counter bore o by the spring q on the pin r within the cylinder f. At the same time the piston t is traveling downward in the cylinder g the valve h, in the cylinder f travels with it, and moves away form the valve seat fn, which allows the water to pass through the port m into the upper part of the cylinder, and out through the port w, into the pipe x, where it sprays through the nozzle x, into the vent pipe y. The nozzle will be pointed to discharge away from the closet bowl, and any suitable design of a nozzle may be adapted, suitable for the purpose. A small amount of the water will find its way of escape through the ports 7 and 6 of thevalve 2, but the port o will provide for the greater, and quicker escape of the water from the cylinder g into the cylinder f. This operation of the valves takes place as the piston il is being forced downward by the seat, and the plate 13 bearing on the spindle m. As the valve h and piston t' are coupled together to operate in unison by the yoke 8, fastened to their respective spindles m and Z, their travels will be simultaneous, and as soon as the weight is removed from the seat the valve and piston start to travel upwards, by the pressure of the water on the underside of the piston t', that has passed through the ports 6 and 7 into the cylinder g. All the time the water is filling the cylinder g, the water continues to spray through the nozzle rv, and continue spraying until the water is cut off by the valve h engaging with the valve seat n in the eylinderf. The valve h engaging with the valve seat n, closes off the supply of water from the spray pipe 9;.

By regulating the port oiingress from the cylinder f into the cylinder g through the valve 2 it will be understood the spray may be continued any desired length of time, and the adjustment may be effected by screwing the plug 3 in or out, and as the weight has been removed from the piston t', the water is free to force its way intothe cylinder g, and the ball p is forced by the water to fit against the port o, thereby closing any inlet through the port o, which will only allow the water to find inlet through the ports 6y and 7 in the valve 2, which will be adjusted to be as slow as possible providing for as long a spraying operation as is neces- Slly,

The iront part of the valve casing is provided with a lug 25, having a series of bolt holes by which it may be fastened to the bowl, or the projection oi the bowl-d.
