pipes of relatively large diameter, in which comparatively high pressures are maintained. The present inventionproposes to provide means for flushing. a bowl capable of use with small sizes of pipes and without theme of tanks and without requiring unusually high pressures.

The important feature of the present invention is the combination with a bowl deis to providea valve for this purpose,

An additional thecasing in which the signed to give the desired distribution pt water, of a valve for cooperation therewith to supply the water to the separate points of distribution in proper sequences and in the desired time relation, to properly flush the bowl, for effecting the desired flow of water through the different channels of the bowl at the proper intervals of time.

Another important object of the invention which shall be relatively simple and sturdy, which is easy to manufacture and capable of withstanding hard usa e.

eature of very great imort-ance resides in the assembly of distributmg and timing valve elements on an operating means in such manner that the .parts may have slight relative movements, whereby they may adjust themselves to irregularities in careful machining of t gree of accuracy as to practicability These and e parts to such a depreclude commercial is avoided.

Fi 5 is a bottom view of the valve member s own in Fig. 4; and Figs. 6, 7 and 8 are dia rammatic views indicating the difierent positions of the distributing valve. Y My improved valve is adapted to be used in connection with a water-closet bowl of suitable construction, in the general manner shown in the patent of Scott No. 196,458 1 Projecting laterally from one side of the bowl A is a valve receiving pocket 16 which is formed integrally with the bowl. The pocket has an upper flange 17, an intermediate flange 18, and a lower flange or edge 19;

nge

chamber 20 is formed between flange 18 and bottom 19, and this chamber opens into a side passage 21 leading down the side of the bowl and under the ottom thereof to the ejector jet 22 at the lowermost end of passage 10.

When water is introduced into the bowl from the rim, the water circles around in the upper part of the bowl, tending to form a swirl, to the center of which the contents of the'bowl are carried.

When the swirling action has been conthe rim is shut off, and the full water directed up into the upleg t rough jet 22, it will be seen that all contents brought below the inverted dam will be ejected or forced'through the up-leg of the closet.

Afterthe stream. of water has been forced through the jet a suflicient time, water may again be supplied to the rim, the water flowing out both the rim and the jet, to restore the normal water level in the bowl.

The valve is designed to effect the distribution of the water in the manner outlined. The valve includes a metal casing or body 25 having a removable cap 26 threaded into its lower end and a removable cap 27 screwed onto its upper end. Formed on the outside of the upper part of the body, which is generall cylindrical, are a plurality of ribs 28 which have threaded surfaces 29 to engage a flanged nut 30. At 31 is an upper ort in the casing, and at 32 is a lower port. *he ribs 28 form bridges to join the different sections of the casing after ports 31 and 32 are formed. These ports maybe formed by setting the casing up in a lathe and cutting tinued a proper length of time, the water to ressure of centrally disposed thereon,

,centra \in Fig. 7. The openin opemng. T

to the composite stem 41-49, the spider be b annular grooves in the casing with an inside cutting tool, until the wall of the easing has been entirel cut away, leaving the sections connected y the ri This arrangement lends itself to cheap manufacture, and provides annular ports in the CBS, ing of suflicient size to pass the necessary amount of water. Below the lowermost port 32 is a lateral flange 33. Below the the water inlet connection, rates the two chambers. This partition has a central opening 38 therein, around which, on theunder face of the partition, is a valve seat 39.

The upper cap 27 has a packing gland 40 through which an operating rod 41 passes; The'u per end of t e rod is threaded and screwed is a knob 42. The knob has a downwardly projecting extension 43 which, when rod 41 is moved downwardly, contacts with nut 40 of the I ment 0 the rod. In order to adjust the distance, the rod may be'moved, the knob may be screwed up and downon the rod, a set screw 44 being provided to hold in adjusted position. v

The lower end of rod 41 has a rectangular head 45 thereon which is received in a transversely extending rabbeted slot 46 in a connecting member or nut 47, this nut having a threaded opening- 48 to receive the upper threaded end of a rod 49. The head 45 has a slight clearance in the slot 46.

Below the nut 47 is a spacing ring-'50 and on the shaft 49, below thespaclng ring, is a flange or washer 51.

In the chamber 35 is a slidable sleeve valve 52 .whichis somewhat like an inverted cup in shape, the valve being hollow, but having a perforated spider 52 at its top, a bottom p an view of the spider being shown in the spider errough. lhe spider through which rod acer 50 being disposed in this e valve is thus loosely secured mits water to pass theret has a central opening 52 49 passes, s

in confined between nut 47 and washer 51.

ecause of the fact that red 41 passes through a packing and, therefore, must moveu'n a straight line, the loose coupling at 45-46 between the rod 41 and rod 49 is provided, so that the lowerrod section may adjust "tself to inaccuracies due to imperfect transverse partition 37- inside the casing, between the two chambers and above definitely sepa-' .the fluted portion is thereto gland to limit the downward move the knob machining or fitting-of parts, without causing rod 41 to bind. If the stem 41 49 were a sin le rigid structure, machining of parts would have to be so accurate as to render its manufacture by ordinary methods impractical. For the same reason, a slight play is allowed between the valve and the stem, as described. a

The distributing sleeve valve 52, which is, of. course, cylindrical in shape, has ribs 53 on its interior for connecting the parts after an annular port 54 is cut in the periphery of the valve, as best illustrated, in Fig. 6. This port 54 is substantially midway between the ends of the valve, dividing the valve into upper part 52' and lowerpart 52". The annular port 54 normally registers with upper port 31 in the casin as shown in Fig. 3, and the lower end oi the valve is well above the lower port 32.

0d 49 extends down through opening 38 and its extreme lower end is threaded and screwed into a metal core 55 in the timing chamber 36. Above its lower threaded end,

the rod 49 is fluted for a short distance, as indicated at 56, and spaced upwardly from a. flange-57. Confined between member 55, which has a flange 55 a Washer 58 on rod 49,

at its upper end, and is a valve member 59.

This valve member is received within a central chamber 60 of member 61. This valve member has an extension 62 on the upper end thereof which has a well 63 therein and is exteriorly threaded. The top of the extension has saw cuts 64 therein. Around the base of the extension is a valve ring 65 held in place by nut 66 on the exterior of the extension. This valve ring is normally held against seat 39 to prevent water entering inlet 34 from passin up into valve chamber 35,. 7

he flutted part 56 of rod 49 passes through an opening in the bottom of well 63, and at 67 is a seat for cooperation with valve 59.

In the well 63, around the rod 49 and con-i fined between the bottom of the well and the flange 57, is a compression spring 68 for urging valve 59 against seat 67. 1

The valve 61, for convenience of construction and to redncethe amount of metal required for it, has an annular channel 69 therein. In the valve body is a passage 70 for establishing communication between the upper and lower ends of the timing chamber. This passage is restricted y a. valve member or sliding pin 71 urged downwardly by a compression spring 22. It is at all times suiiiciently loose to provide for a slightleakage around it.

At 73 isa compression sprin for urging member 55 and the valve 61 an position.

valve on the the various parts connected therewith upwardly to closed a reciprocable valve I 1,eeo,aca

The valve B is put into the pocket in the bowl by insertin it through the bottom of the pocket. As t e bowls are manufactured .from clay, diflerent bowls are not the same and each one will have irregularities different from others. A soft rubber gasket 75 is accordingly placed on nut and a second one 76 on flange 33. Nut 30 is adjusted by fitting the valve into the pocket, determining the proper position for the nut, removing the valve, and setting the nut. Nut 30 may thus be set soas to bring gaskets 75 and 7 6 against the flanges 18 and 19, respectively, to be forced into sealing engagement therewith. A gasket 77 is then placed on flange 17.

During the fitting of the valve, knob 42 and cap 27 are removed. Cap 27 is then aplied, and screwed down, compressin gasket 7 and lifting the valve body, there y com pressing gaskets 75 and 76. Thus, the valve is quickly fitted to the bowl. When so fitted, port 31 opens into chamber 15 and port 32 opens into chamber 20.

Before knob 42 is applied, a porcelain hood 78 may be fitted over the pocket and valve, this hood having 'a metal bushing 79 clamped therein to guide the knob. The

knob may then be appliedand-screw 44 is set. Because of the head 45 being rectangular, rod 41 is held against turning with the knob as the knob is screwed down.

The parts of the valve are normally in the position shown in Fig. 1. The inlet water pressure communicates to the lower end of the valve body 61 through passage 70, so that the inlet pressure and spring 73 both tend to hold ring 65 against seat 39.

When knob'42 is forced down, flange 57 first moves down against the end of extension 62, unseating valve 39, allowing the water in the timing chamber 36 to escape up into the well around the fluted portion 56 of the stem, and breaking the resisting pressure of this water. This immediately establishes a differential pressure between the inlet water and the water in the lower end of the timin chamber, as Water will not flow as rapidly t rough passage as it escapes into the'well. I

As soon as valve 59 o ens, and the differential pressure is estab ished, the plunger maybe easily forced further down, unseat ing valve 65. The area of valve member 61 exposed to inlet pressure downwardly is then greater than the area subject to upward pressure, and the plunger will be assisted in its downward movement by the water pressure. Consequently, the plunger, as the entire reciprocable assembly may be termed may be easily forced downwardly by a sing e ap lication of pressure in a very short erio of time. The downward movement W1 lbe limited by the knob, as hereinbefore described.

When the knob is forced down to its-lowermost extent, distributing valve 52 is moved pressures,

- down,

.pin and the valve eludingI limited movement a corresponding distance. Port 32is covered by surface '52" of the valve 52, while port 31 is uncovered. Water coming into pipe 34 passes through opening 38 and up through the top of the valve and out port 31 into chamber 15, as illustrated by the arrows in Fig. 8.

'32 is uncovered and port 31 is covered by area 52' of valve 52. Then all the water flows-into chamber 20. The position of the parts is shown in diagram in Fig.7.

Finally, port 54 in valve 52 comes into register with port 31, and the flow of wateris divided until valve 61 is again moved up to closed position. As port 31 is wider than port 54, the time interval between the time when port-54 first registers with port 31 and the valve 61 has finally closed will be appreciable,and for a short duration of time, watcr will flow through both ports 31 and 32, as indicated in Fig. 8.

Thus, it will be seen that the valve will first supply water to the rim of bowl A, then to the jet, and then to both the rim and the jet. By concentrating the entire flow first into the rim and then into the jet, greater efiiciency is obtained with less water and smaller-supply pipes may thus be used, than with any present type of'flushing valves. Neither need the water pressure be very great to effectively flush the bowl.

Where the water is supplied at very high it is desirable that the valve close more quickly than when the wateris at low ressure. Proper adjustment may accordingly be made by adjusting knob 42 to allow for a .horter movement ofthe parts when the pressure is high and a greater movement when the pressure is low.

Pin 71 is made of suflicient length ,to'engage cap 26, so that when the valve 61 moves ited, and a relative movement between the may be effected. This tends to keep the restricted passage around the pin from becoming clogged with solid particles.
