.T at?, whom zit may concern; y

Be it known that I,v THOMAS F. PAYNE, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Water-Closets and Flushing-Valves Therefor, of which the following is a specification.

My invention has relation to water-closet and iiushing-valve in which the ordinary i pressure of the street-main is used for ushing,

and thus obviating the use of aseparate tank for each closet. In water-closets and valves of this class `heretofore inuse the valve is usually closed by the pressure of a minimum quantity of water which is ermitted lto escape from theservice-pipe t rough a minute orifice to the top of the plunger into a chamber in which the plunger slides and upon the top of the valve, and thereby as the amount of water in the upper chamber increases the pressure upon the top of theplunger closes the valve. There are many serious obj ections to this form of a valve, the rincipal one being that the orifice through W ich the Water is carried from the inlet to the top of the valve is necessarily of minute diameter and will of course in time become clogged and closed up. This objectionable feature is greatly increased wherev the water contains any impurities-such as mud, sand, lime,

acids, &c.-as any of these ingredients are apt to clog up lthe minute orifice, and thus prevent its operation, also in many cases inding and grinding the piston or plunger and the walls of the cylinder in which the piston slides, causing leakageand interfering with the operation of the valve. Another defect in this form of valve is the attachment ofthe handle to the body of the valve, this attachment being imperfect and causing leakage. Another objection in Siphon-acting closets heretofore in use is the large water- My invention further consists in the construction, combination, and arrangement of parts more fully described hereinafter and specifically pointed out in the claims.

In the accompanying drawings, illustrating my invention, Iiigure 1` is a vertical sectional view of a valve illustrating a part of my invention. Fig. 2 is a vertical sectional view atrright angles to Fig. 1. Fig. 3 is a vertical sectional view of the closet. Fig. 4 is a top view of the same.

The casing of the valve consists of three separate castings 1 2 3, the portion 1 being the main body of the casing, the central portion 2, which is attached to the upper end of 1 by means of a threaded socket, contains the controlling device, which controls the closing of the valve and is separated from'the lower portion 1 by means of the frictionless packing or folding diaphragm 21, which, as shown in the drawings, has its upper end bent over and serves as a washer between the inner connecting-partition 5 and 6. The casting 3 is attached to the upper portion of the part 2 by a screw-socket, a suitable packing between the two reventing the escape of .the liquid containedp in the interior of the chamber 2 A threaded socket 7 in the side of the casing 1 is provided with ordinary coupling devices for the attachment of an inlet-pi e from the water-supply, and

an opening c osed by a plate 8 permits the insertion of a lever 10, having a handle 11, attached to a shaft 12, by means of which the valve is raised. At'the bottom of the casing 1 is a coupling 13, which is attached to the inflow of the closet and through which 4thlwater after passing through the valve passes into the closet. The valve 14, seating in a partition 15 has attached to its bottorn a cup 16, closed at both its ends and having an inlet-port 17 in its upper portion and an outlet-port 18 in its low er portion.

`When the valve is raised by means of the lever 10, the water passes from the inlet 7 into the opening 17, which is then above the valve-seat 15, and passing through the body of the cup into the channel 19, through the port 18, and from thence into the channel 20, which leads to the flushing-rim of the closet. A folding diaphragm 21 having its lower edge attached to the upper portion of the valve 14 and its upper edge attached to casing 2, prevents the passage of water into chamber 2. A rod 21", attached to the up- IIO per side of the valve 14, passes through the l channel 29 and jet 29 of the bowl of the center of this folding diaphragm and is attached to a valve 22, situated in the chamber of the casing 2. This valve 22 seats itself upon an opening in a plunger 23 and hason its lower portion lugs 24, which when thel valve is raised a short distance come in contact with and raise the plunger 23 to the top of the chamber 2 in the casing 2. A rod or screw 25, which is attached to the top of the valve 22 and has an orifice 26 through the center of its lower portion and openings 27 in its side, is also attached to the top of the valve 22. The chamber 2 is adapted to contain and should be filled with a l1 uid, which liquid may be glycerin, water, o1 or any other suitable liquid.

When the valve 14 is raised from its seat and the plunger 23 is raised to the top ofthe casing, the liquid contained in the chamber 2 1s forced by the raising of the plunger from the upper portion of the chamber through the opening of the valve 22 into the lower portion of the chamber and maintains the valve 14 and its connections in an elevated position, permitting the water to flow, while the valve remains raised, from the inlet 7 through the port 17, cup 16, port 13, and channels 19 and 20 into the rim 32 of the closet. When the handle 11 is released, the weight of the handle, together with the weight of the valve 14 and its cognate parts and the frictional pressure of the water passing through the valve 14, causes the square rod 21X to drop sullicienlly to close the valve 22 on its seat in the piston 23. This prevents the return of the liquid from the lower portion of the chamber 2l to the upper portion through the comparatively large opening of the valve 22. This same pressure of the piston 23 under the weight of the valve 14 and cognate parts, together with the frictional pressure of the water passing through the valve 14, also causes the liquid in the chamber 2 to flow slowly through the smallpassages 27 and 26, and thus pass from the ower to the upper portion of the chamber 2 permitting the piston to gradually descend in the chamber 2 as the liquid is displaced and permitting the valve 14 to close on its seat.

During the period the handle 11 is raised and also during the period occupied by the first part of the descent of the handle 11, the rod 21X, and the valve 14 the water from the supply 7 passes, as already described, into the rim 32 of thel closet and continues to pass thereto until the port 13 in the cup 16 is carried from the channel 19 to the channel 19X.

As soon as this takes place and the port 13 is brought into conjunction with the channel 19 the water from the inlet 7 ceases to pass through the channels 19 and 20 to the rim 32 of the closet and commences to pass through the channfls 19X and 28 of the valve to the closet and also, if desired, to a shortI auxiliary rim-channel 33. This fiow of water through the channels 19 and 28 continues until the valve 14 is closed.

When the cup 16 descends to the position where its ports 17 and 1S are respectively in front of the channels. 19 and 19 and before the valve 14 is seated, the water passes through both of the channels 19 and 19X, and its force and volu1ne`being thus divided the closet ceases to Siphon and the water acts as a refill until the water ceases to fiow. As the port -17 is somewhat greater in depth than the depth of the valve-seat 15, the flow of water from the chamber 4 throuO-h the port 17 to the channel 19 will take place during the closing oi the valve. Y

The closet, as illustrated in Fig. 3, has a hollow rim or chamber 32 extending around the circumference of the closet, in which chamber is a partition 30, and where it is de-v sired there may be a second partition 31. The chamber 32, as alread described, conimunicates with the channelr20, and 1t is provided with perforations 32X, made at such an angle that the water fiowing-through them will produce a swirl in the closet. The purpose of the partition 30 is to cause the water to flow in but one direction through the chamber 32. .l

The means for carrying the water from the channel 20 and 28 to the body of the closet is composed of what I term a ftwin ipe or connection, which is made in a sing e piece 34, having central partitions 35, thus obviating the use of two separate pipes and their connections, and. thereby lessening the cost of the fittings and also the danger of leakage arising from an increased number of joints. I also provide a washer 36, having a partition coincident with the partitions in the pipe 34, so that a perfectly tight joint will be formed between the pipe' 35 and the connection 36, suitable washers being interposed between them, the coupling 13 having an elongated flange through which bolts pass for its attachment to the closet.

The operation of the valve and the consequent delivery of the water first to the rim of the closet, then to the jet, and then to both the rim and the jet has been fully described in the description of the parts. The effect of the delivery of the water in the closet is as follows: The water which passes to the chamber 32 of the rim of the closet passes from the saine at an angle under pressure, thus producing a swirl which piles the water in the bowl, retarding its flow therefrom and scouring the bowl. As soon as thel water ceases to pass through the chamber 32 and while the water is piled up in the bowl the jet action through the jet 29X commences. This jet, also being under ressure, strikes the solid body of water in t 1e up-leg of the bowl and lOO IOS

IIS

spreading somewhat therein ushes this body of water contained in the up eg over the dam 50 of the trap and into the drag-leg 51, forming a solid plug of water in the drag-leg '51 and cross-leg 52, thus producing a combinedsiphon and ejector action. This combined action of the water draws the contents of the bowl after it through the legs of the closet. While the combined siphon and ejector action is taking place, Aif the bowl is provided with the cham ber 23S-water will flow through the channel 29, through the chamber 33, and

into the closet.

To prevent the water which flows through the casing 1 from escaping through the orifice by which the handle-lever enters the casing' and to obviate the necessity of a packing-box which is liable to permit leakage and create friction, I employ a flexible diaphragm 39, which, as shown in Fig. 1 of the drawings, is placed in the lower chamber 40 and is held in position over the opening thereof by means of the plate 8 and the bolts 9. The lever 10 passes through this diaphragm and is closely clamped thereto by the screw 41 drawn into the bell-crank 42. The flange 43 pressing against the outside of the diaphragm 39 prevents the escape of any water from the chamber 40 to the outside and through the opening through which the handle-shaft enters, and this opening does not, therefore, require to be packed. This folding diaphragm consists of -a single piece of exible material,

such as rubber, or I may,if I desire, make it of thin metal-such as steel, brass, &c.- which will bend sufiiciently to permit of the easy o eration of the lever 10. I have also embo ied this same rinciple in the diaphragm 21, placed in t 1e chamber 4 to prevent the passage of water 'into the liquidchamber where the same is made in the sha e of an accordion plait, although it might e made as a simple elastic or pliable cylinder.

The advantages of my invention result from the combination of a direct-pressure alternately-acting valve with a closet-bowl having rim-oriiices adapted to produce a swirl and a jet directed toward the up-leg of the bowl; also, from the combination of this bowl with a valve having a retarding device acting entirely independently of the water in the main. c

The advantages `resulting from the construction hereinbefore described are that the closet is positive inaction, that it has a joint and combined siphon and e'ector action, which effectually cleans the owl without any pounding or noticeable noise, that it acts with but a com aratively small amount of water, requiring ut a small sup ly-pipe, and that the parts are not liable to lbakage or to get out of order. y v

I do not desire to limit my invention to the order of the flow of water through the channels leading from the valve, as herein deby Letters Patent, is-

scribed; nor do I desire to limit myself to the form and arrangement of parts shown in the drawings and described in the specification.

Although I have described the valve and bowl combined to produce a new and useful result, I do not desire to abandon my right to embody the useful and novel features of these parts independently of each other in separate applications for Letters Patent.
