FLUSHOMETER.

Application filed May 31, 1922. serial No. 564,823.

To all 'whom t may concern:

Be it known that I, THOMAS R. Bncos, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invent-ed new and useful Flushometers, of which the following is a specification.

' This invention has reference to lushometers, that is, to flushing attachments for toilet outtits'for causing an ample flow of water for a suitably prolonged period of time, to properly flush the toilet bowl, without requiring the presence of a flush tank.

The object of the invention is to. provide.

a structure by means of which a flowof water directly from a service pipe may be delivered to the toilet bowl without causing hammering or other objectionable noise. l

In accordance with the invention, there is provided a structure of small size, which, after being started, will automatically maintain the full initial flow of water for the entire time `for which the device is set, and will then close or shut off rapidly, with the speed of closing such that the flushing will not cause siphoning to deplete the desirable quantity of water which should remain in the bowl. I

lThe invention will be best understood `from a consideration of `the following detailed description taken in connection with the accompanying drawings, forming part of this specification with the understanding, however, that the invention is not confined f to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as eX pressed in the appended claims.

In the drawings:

AFigure 1 is a longitudinal vertical section of a flushometer constructed in accordance with the invention, with the parts in position to begin the iushing operation but before the water is turned on.

Figure 2 is a section on the line 2 2 of F ig. 1;

Figure 3 is .a plan view of thje structure of Fig. 1 with the cap removed;

Figure 4 is a plan view ofa pressure retaining device-employed in the flushometer;

employed-in the device.

Figure 5 is a plan view of a' guidingspiderdiameter than, the upper fend.v The lowerA end 2 of the casing is formed with an exteriorly threaded outlet 3 for connecting the :liushometerl to a Hush bowl by the usual fittings, and the upper end of tl'ie casing is closed by a cap 4 of appropriate size andv shape and provided with a gasket 5 for her metically closing the upper end of the casing. In order to facilitate the application ofthe cap 4, said cap is formed with an integral nut 6. Formed in one piece with and projecting` from one side of the upper end of the casing is a'neck orV connection 7 with internal screw threads 8, whereby the casing-may be coupled to and supported by a service pipe (not shown), to providea supply of water under service pressure, and available as needed. p

lFVithin the lowerend 2 of the casing and concentric therewith is an extension 9 rising centrally into the upper end 1 for a short distance. Branched laterally from the lower end 2 of the casing 1 is a neck 10 having eXterior'screw threads 11 to receive a cap nut 12 with a centrally located, outwardly flaring opening 13. The nut` 12 houses a washer 14 and a gasket 15, against the outer yend of the neck 10. The washer 14 has a cup-shaped axial extension 16 of a size to fit in the neck 10, and at theend remote from the washer' 14 carries a plate 17 cooperating with which is another plate 18 confining a helical spring 19 between it and the first-named plate 17. The plate 18 has an axially extending stem `2O passing' through the plate 1 7 and also through a Such cylinder;

packing gland 21, which latter confines a mass 22 of packing, material in a pocket 23 formed in that face of the plate 17 rembtel from the plate 18.

Lodged inthe extension 16 and between the plates 17 and 18 is a frusto-conical head 24 on a stem 25 carried by a handle 26 which may be made integral with or be otherwise,

secured to the head 24. The opening 13 of the nut 12 flares outwardly so that the handle 26 may be rocked sidewise in different directions, thus causing the head 24 to similarly rock within the space between the washer 14 and plate 18, whereby thev head 24@ under the .action of the handle 26 will f along the inner wall of thecasing 1, the nut plunger.

31 being screwed into the upper end of the The nut 31 is formed on the interior with a spider 32 extending inwardly to another nut 33 in theoform of a hub. The hub 33 has` interior screw. threads carrying `an adjustable sleeve 34 of considerable length and provided with an upper end 35 of hexagonah outline. This sleeve is madeadjustable to control the time of liushing. I l

The plunger 28 is contracted in diameter from the ledge 29 downwardly and then has an expanded portion 36 poverhanging the up-l ward extension 9 of the lower section 2. lDropping from the overhanging portion 36 is a hub 37, with an exterior thread 38 to receive a nut 39 and having an `expanded ledge 40 forming a shoulder to vconne 'Y washers 41 and 'w42 in superposed order against the portion 36. The washers 41 and 42 are held agaimvtv the ,portion 36 by the clamp nut 39 having spanner-receivlng sockets 43. These parts constitute a valve carried bv the plunger..

'Depending centrally from the nut 3 7 '1n one piece therewith is a'sleeve 44, terminating at the lower end iin an exterior-ly threadi ed portion 45, to which there 1s applied an interiorly threaded nut 46 having depending legs 47 of suicient spread to lit the inL -terior of the lower end 2 of the casing, so as to slide therealong and guide the parts carried thereby.

Located within the lower end 2 of the easing, is a sleeve 48 having an exterior taper wall 49, with the sleeve of a greater diameter at the lower end than at the upper end, and at the upper end joined by a spider 50 to a ring or hub 51 entering one end of a helical spring 52 supported at the other endby the nut 46, -the spring 52 tending to hold the nut 46 and the ring 51 apart, but in' such manner that they may be elastically held. The sleeve 48 contacts at its upper end with the clamp nut 39 forming part of the valve structure. The spring 52 together with the taper sleeve 48 constitute a pressure retainer for the liushometer and forms an important element of this invention. lIt automatically adjusts itself to the amount of water supplied.

Formed on the inner wall of the lower casing member 2 and extending toward the neck 10, is one member 53 of an elbow 54, having the other. member 55 of the elbow upright and in line with the longitudinal axis of the casing l. The elbow member 53 with a series of notches or grooves 58 about its exterior, and provided with'an axial stem 59. The stem 59 is 'surrounded within the bore in which it is housed by an expanwhile the other or` outer end of the nut 66 ends in a hexagonal ornon-circular head 68 confining a packing ring 69 between it and theouter end of the elbow member 53. The" spring 60 serves to hold the valve 63 against the valve seat 67, with the stem 61 slightly spaced from the adjacent end .of the stem 20 when the handle A26 is held in the straight projecting or axial position.

The passage 64 centrally through the elbow member 54, has ataper termination or seat 70, into which lits a taper head 7l, on the lower end of a fixed tube 72, having a counter bore 73 throughout a portion ofits length. The head 71 forms a ground joint connection' with the taper seat 70 and the two parts are held together by a cap nut 74 applied tothe exterior of the elbow member 55. The tube 72 rises through the sleeve 44 lin closely spaced relation thereto, and the tube 72 also rises through a washer 75, held onto the expanded portion 36 by a clamp nut 76 and, for ease of manipulation, is provided with Spanner sockets 77.

VVithiu the tube 72 above the base of the i counter bore 73,'the1e is lodged a spring 78 bearing at the lower end against the base of rthe coun-terbore 73 and rising for a distance thereabove. Within the counterbore 73 there is lodged a tubular member 79 to slide therealong and which is carried at the4 upper end by a rod 80' rising through and above the tubular member 72. The tubular member 72 has a port or passa e 81, through its walls, so as to be norma ycovered by the internal cylindrical member. 79 'which serves the function of a valve therefor. The upper end of the rod 80,`when at its point of highest elevation, projects beyond the to'n of the tube 72, and is provided with a washer 0r valve 82 held to the tube 80 by a nut 83, -the washer 82 being of a size to fit the upper end of the tube 72. Extending through the side walls of the plunger 28 is a tube 84 of small bore, having its outer end reduced, so small in diameter as to permit only a dribble of Water from the los j service connection 7 t0 the interior of the casing 2, and to prevent clogging of the tube by small particles.

1f it beassumed that the `tlushometer is installed and water undery pressure is supplied to the neck 7, the end 1 of the casing above the plunger 28 is quickly filled througli the tube 84 with water under service pressure in orderto equalize the pressure above and below the plunger.

During the initial 'filling of the ushometer with water, the handle 26 remains in a horizontal or closed posit-ion and the valve 68 remains closed. lf now, the handle 26 be rocked, the head 24 is tipped or rocked, pressing against the plate 18 and compressing the spring 19 to force the stem 20 against the stem 61 and, in turn, compressing the spring y s0 that the valve 63 1s moved away from the valve seat 62, where. upon water which is in the tube 72 and some of the water in the section 1 above the plunger 28 will How 'down through'the tube 72 and passage 64 and into vthe iiush bowl, relieving the pressure abovethe plunger 28 so that the service water may now lift the plunger to open the escape passage for water around'the upper end of the extension 9, in order that the full flushing of the bowll may take place. v

When the plunger rises, it carries the sleeve 34, and when the latter reaches the valve 82, it closes the space between such valve and the seat at the upper end of the stationary tube 72, so that the pressure ot water in the upper end of the upper casing member 1 forces the valve 82 down into the sleeve 34 until it seats on the upper end ot' the tube 72, and is there held by 'the pressure of the water from above. The parts are so proportioned that when the valve 82 is seated on the upper end of the tube 72,

the port 81 is opened by the hollow or tubular member 79,1alli'ng below the port by means of the rod 80.

Then the plunger 28 is up, water from the supply entering through theJ neck 7` passes down and' withinv the upper; end ot the extension 9, because at this timethe .washers 41 and 42 are raised above the over the top of the sleeve past the ring 50' within the sleeve 48 and down around the elbow 54 and out into the outlet 3 and thence -to the bowl of the toilet, to fully Hushv the same. It should be noted here that the resistance of the spring 52 tothe opening or loutlet thus formed when the pressure retainer is forced downwardly by the water, may be adjusted and regulated at will to suitthe pressurel in the main and the amount of water desired to flush the bowl by simply tightening or loosening the nut 46. The nut carries the diverging legs 47 which slidably contact with the bore-of the lower portion 2 of the cylinder or casing to guide the plunger v28and .the parts carried thereby, in their upward and downward movements. It is further noted that the tapering sides of the pressure retaining sleeve 48 act as a flange or abutment to receive the impact ofthe water, which forces the sleeve downwardly against the resistance of the spring 52. The sleeve `is always housed, more or less, within the extension 9 during its upward and downward movements'with the plunger.`

By the rapid outiow of the water, thus permitted, the pressure in the main and in the casing above the outlet is reduced,

"which permits the expansive force of the spring 52 to gradually close the sleeve 48 against its seat at the underside of the valve, the time required for such closing depend# may bel varied by the adjustment of the nut 46, to increase or decrease the resisting power of the spring 52. In the meantime the space above the plunger 28r has been filling again through the tube "84, since the upper end of the stationary tube 7 2 is closed by the valve 82, and the outlet 81 is closed ing on the pressure of waterat hand and j by reason ot the fact that the washer 75 is now above `the same. The combined pressure 'of this water above the plunger, to-A gether with the weight thereof and that of the plunger, assistedv by the pressure of the water in the casing below the plunger bearing upon the expanded portion 36, now

forces the plunger downwardly carrying the valve against its seat on the extension 9, and closing the outlet, when the {iushingV action ceases. The adjustable sleeve 34 is simultaneously lowered by the. descent of the plunger 28 to uncover' the valve 82 when the heretofore conlined pressure ofl the water loses its effect thereon and the spring 78 is-allowed to expand land raisethe valve 82 oli' of the upper end of the tube 72, and in so doing the hollow sleeve valve 79 closes the port or outlet 81, the washer 75 now being below the same.

At this time the chamber above the plunger 28 will again receive its full charge under pressure through the tube 84 to assist in holding the plunger and valve down against its seat and prevent any leakage, the parts now being in normal position, as Figf ure 1 shows.

This sequence of operationv takes place whetherthe handle 26 be held in 'inclined above and below the plunger.l y When the plunger' 28 falls and brings the washerr 75 below the port 8l, the water then enters the tube 72 through the port and fills the tube. 1f the handle 26 be held open, water simply "dribbles through the port 81 and out past the'valve 63, but as soon as the handle is released, the valve G3 i`s closed, and the water entering by. way ot the port 8l fillsthe tube 72, andas soon as the pressure of the waterin the tube 72 equals that within the upper member l of the casing, the valve 82 rises by pressure of the spring 7 8, ready for another flushing operation.

vIt should be understood that if the pressure retainer be adjusted to close at a given pressure; that is to say, if the spring 52 is of a strength equal to the amount of pressure desired to be retained in the casing tor the purpose `of operating the plunger 28, then lall the water supplied over the predetermined pressure will force sleeve 48 down and let the water escape into the bowl. If it is not supplied, the bowl will not get such 'a `complete flushing, lbut the plunger will close just the same, for 'there must always be `above the amount required to close it, otherwise the sleeve 48 would remain closed. In other words, theobject of the retainer is to hold back sufficient back pressure beyond the pipe extension 9 so as to have force enough in the waterto force down the plunger 28. This does not require a very great pressure, but that pressure must always be there to close the plunger and its valve.

T he stationary tube T2 in connection with the passage 64 constitutes a conduit for water leading from the upper compartment Voi the casing tothe lower compartment,

which conduit is closed vat its lower end by the valve A68 and at its upper end by the valve 82.

When the flush is in operation and the water is liowing into the bowl, the spring 52 is compressed vand the pressure of the water pressing on the abutment or beveled sides of sleeve 48 hoidsthe spring in this compressed condition during the full time that the flush is taking place. When theA plunger 28 is lowered and washer 4:1 draws near the extension 9 and the space between washer 41 and extension 9 equals in area that throughv spider 50 in sleeve 48, then as plunger 28 descends further from that point, spring 52 ex ands and sleeve 48 rises to its seat, but on y as the water pressure is taken Vfrom it by the closing of washer L11 on the end ofthe extension 9.

` plunger.

This pressure retainer has two purposes;

' the first being to always assure pressure for raising the plunger 28 to any height required, regardless of the amountl of water supplied, and it does thisv because there must always be the amount of pressure retained according to that which the spring 52is set for. The second purpose is to assure 'pres-V ber under the same, by reason of the fact that extension 9 is not present above the plunger, so that the pressure of water in the chamber above plunger 28 always equals that of the pressure in the chamber beneath it; Still the upper chamber contains double the area under pressure of the under side of Thus when the'valve is operated, the plunger raises very fast to the point set by the sleeve 34, when it immediately starts to return and during the return of plungerv 28 the bowl is receiving all the water the pressure retainer will permitlto pass, and at an equal volume until such timel as washer 4l and extension 9 draw together, when the liushing gradually ceases.
