FLUsHIivG APPARATUS.

Application filed December 22, 1924. Serial no. 757,435.

T all whom it may concern:

Be. it known that I, LEO SIMMONS, acitizen of the United States of America, and a resident of Washington, District of Columbia, have invented certain new and use ful Improvements in and Relating to F lush-v ing Apparatus, of which the following is a specification.

This invention relates to improvements in flushing apparatus; and the nature and objects of the invention will be readily understood bythose skilled in the 'art in the light of the following explanations of the accompanying drawings that illustrate what I now believe to be the preferred mechanical expressions or embodiments of my invention from among other forms, constructions and arrangements within the spirit and scope thereof.

An object of the invention is to provide improvements in combinations, constructions, and arrangements with the end in View of producing an exceedingly desirable and improved apparatus or so-called valve. .VVith this and other objects in view my invention consists in certain novel features, combinations and constructions as more fully and particularly explained and specified hereinafter.

Fig; 12 is a detail perspective of the rotary outlet controlling valve of the dash pot.

Fig. 13 is a section on the line 1313, Fig. 3, on an enlarged-scale; I

In the particular example illustrated for purposes of explanation, an elongated usually vertical casing is provided consistingiof several longitudinal alined hollow or tubular sections usually detachably united orcoupled together through the medium of water-tight screw threaded couplings or connections. For instance, the casing can be composed of a top end tubular section 1, an intermediate section 2, and a lower end section 3,although I do not wish to so limit all features of my invention.

In this particular example, the top section 1 provides a chamber for the pressure or service water and a flushing water outlet or port through which the flushing water enters the section 2. The section 2 provides aflushing water chamber or passage having a flushing water outlet for connection to the toilet to be flushed. The section- '3 carries the dash pot and provides a water well open I to the flushing water passageof section 2, The tubular section 1 is normally closed at the upper end water tight removable top closure, and at its lower end provides a flushing water outlet duct or port 1, longitudinally alinedwith the casing sections and discharging into the upper end of section 2. The lower end of section 1 pro 'vides an annular upwardly facing ledge surroundlng said outlet l and forming a seat or supportifor the usually flexible annular heavy packing washer 4. The flu shing water port ordischarge through this washer is normally closed by main flushing valve 5, and auxiliary or pressure relief valve 6, as more fully set forth hereinafter.

In this example,-the top section 1 is formed, between its upper and lower ends,

with a lateral or side service or pressure --water inlet 1*, formed for coupling to any suitable service or other pressure water supply pipe or connection 7 j The otherwise open upper'end of section, 1

1, is normally closed by a removable end pressure-water closure cap 8, having a depending internally threaded flange 8 that surrounds and screws over the externallythreaded upper end of section 1. This closure is usually provided with an internal packing washer 9 to form a tight joint. The closure cap 8, is formed with a fixed central vertical upstanding post or spindle 8 closed against passage of liquid from the interior of the casing to the exterior of the closure, and the closure is formed with a vertical guide bore 8, longitudinally of said post and open at its lower end into the cas ing. This guide bore loosely and slidably receives the upstanding longitudinal guide stem 6 rigid with relief valve 6. The post 8 is exteriorly formed to provide the closure with rigid nut or wrench receiving faces 8 the exterior portion of the post above nut 8, being reduced and screw threaded, to provide ledge or shoulder 8 on the nut.

The'upper side of the approximately flat top of the closure, is also preferablyformed with an annular ledge or shoulder 8 adj a cent to the junction of the depending flange 8 with said flat top. These shoulders or seats 8 8, are designed to receive the top and lower edge, respectively, of a removable cup-like perforated cover cap 10, confined to the closure by any suitable means, such as cap nut 11, for instance. The approximately flat top wall of the cap 10 is formed to rest on the shoulder 8 and is perforated,

for the passage of threaded post 8 The lower edge of the depending annular wall of cap 10, is formed to fit and be centered by the seat 8. The clamp nut 11, is formed to cover the projecting post 8 and removably screw thereon down onto thecover cap. The exposed surfaces of the nut 11, cover cap 10, and end closure 8, are nickel plated or otherwise polished and finished, to comply with present trade conditions with respect to bath room and like plumbing fixtures.

Access to the flushing valves 5, .6, the washers, and certain other interior parts of the apparatus, is gained by unscrewing and removal of the pressure cap 8. The wrenches usually employed by plumbers and mechanics seriously damage and mar the exposed ornamental plated or finished polished surfaces of plumbingfixtures to which such wrenches must be applied. I hence provide the readily removable ornamental exteriorly finished perforated slip cover cap 10, that must first be lifted from the casing, before the pressure cap 8, can be reached for removal, and that normally covers and conceals those surfaces of the pressure cap that must be engaged by the wrench during the operation of removing the pressure cap. The surfaces of the pressure cap covered or concealed by\the perforated cap, can hence be left unfinished and not in condition to be post 8 and the top of the pressure cap 8,

and as readily reapplied. When in normal position, the exposed surfaces of the pressure cap, cover cap and clamping nut 11, provide a compact apparentlyone piece finish at the upper end of the casing. The perforations.

10 in the cover cap are intended to be clearly visible to the plumber or mechanic for the purpose of indicating the presence of a mere finishing cover that does not enclose a water space or chamber and that must be removed to gain access to the pressure cap, ntending to warn the plumber or mechanic against applying a heavy rough tool such as a pipe wrench, to the cover cap.

In the specific example illustrated, the

washer 4, isclamped againstits supportingledge by metal ring 12, and this ring is held down on the outer edge portion of the washer by spaced upstanding vertical arms 1%, rigid with the ring, and the spider-like frame consisting of said ring. and arms, is held down by ring nut 13, screwing into the internally threaded upper end of easing section 1. The frame consisting of the ring and arms is removable and slidable longitudinally along the cylindrical inner surface of thesection 1, and is held. against rotation therein by longitudinal rib on the outer surface of the upper end of one of said arms slidable vertically in avertical longitudinal groove in theinner surface, of the upper end of the section 1.

On removal of the end closure the ring 'nut can be adjusted to tighten or loosen the washer, and on removal of the nut, the ring and its arms can be removed to permit removal of the washer. The arms do not obstruct the service water inlet and do not interfere with or obstruct the flushing valves or the cooperation of the washer 4 therewith. V

The lower end of section 1 longitudinally telescopes with the upper end of section 2 and said section ends are oined together for longitudinal removal by longitudinal intermeshing screw threading, and the sameis true of the meeting longitudinally telescoping lower end of section 2 and upper end of section 3.

In the example shown, the flushing and relief valves are of the lift type and seat by gravity and water pressure. The main valve 5, is usually of metal, conical in shape, and fits and depends within the washer 41, and is formed with a central vertical pressure relief duct 5*, leading from the water pressure chamber in section 1, to the flushing I water chamber or passage in section 2. This relief passage is normally closed by the 00111- cal relief valve 6, usually integral with guide in said recess on said shoulderand the valve '6 normally seats on the 'washer-and"extends down'into the centralopeningthereoiif The washer 5? is removable. and is normally formed with a central Vertical longitudinalclamped to its supporting shoulder by removable ring 5, screwing down into the rece'ss in valve 5, and formed with an openwork upwardly extending spider like fraine 5 projecting. abovethe relief valve 16,-and spaced upwardly therefrom in position to be engagedflby the upper end of the relief valvewhen that valve has completed its'upward movenient relativeto the valve 5 and instituted the pressure relief flow of water through duct 5*, of valve. 5." Continued up ward movement of valve 6, thenliftslthe valve 5, and the two valves? thenvcon tinue their upward strokes together, and thevalve 5 remains loosely suspended from the upper end of valve 6, while valve 5',remains above its seat. The lifting or stop frame 5', is nor mally spaced from. valve 6Tand' 'is always open to water flow,ltherethrough, and the main valve 5 is hence loosely hung by-said frame and is free for lateral swing or" movement with respect tovalve 6 to permit relative lateral freedom ai'idz-propericentering and seating on its Washer. The casing section 2," intermediate its. ends, is formed with lateral or radial'fiushing Waterroutlet-Q, formed to 'receive iflushing water pipe or other connection 15, for attachment to the toilet or other device or apparatus to be flushed. I

The otherwise open lower endof section 2', is closed bythe section 8, the upperfend of which is removably unitedto the lower end-of section- Q'by a screw threaded connection.' -f r Y The well sectionl3 is hollow, closed'at'its lowere'nd, and open at its upper end to the flushing water chamber or'pass'age' ofsection 2, and its annular vertical walland lower end, are closed against passage of water therethrough. 1 v A vertically elongatedi open-upper end dash pot cup 16, is carried by and arranged longitudinally of and within section 3 in normally fixed relation theretof This J cup 8 is of reduced externalZcrossTsectional dimensions throughout its length'with respect to the internal dimensions of section'i'r3; to

provide a water well 17, withirisectionw surrounding the vert-i'eal-wallof cup 16 and between the'lower ends of the cup andrsection 3, with said water vwell open at its upper end to the flushing waterchamber of section 2.- This cup is mounted in an elevatF- ed position in the section. 3, in the particular example"illustrated, through the medium,

of a tubular nipple 16", forming a reduced central" longitudinal rigid eXtens ionof' the cup'and" depending from the otherwise closed floor or end wall thereof. The longitudinal bore of thi'sjrigid extension nipple "ex'tends'completely through the nipple and at its upper end opens into the cup through the floor thereof.

The' bottoni end w-all of section 3," is

ly screwed threaded bore th'erethrough. The cup-issecured to and in section 3, by inserting the cup longitudinally into'the sectioirthrough the open'upper end ofthe seeition, and screwingtheni'pple 16, into said bottom bore of thesection', preferably, until the flange or annular shoulder 16 of the nipple" tightly abuts the top f ac'efof 'the floor of section 'The lowerend of the cup'is held elevated above theffloor ofsection 3 by the non-threaded base or upper length of nipple 16, between shoulder 16*, and the cup fioor or endylocated in the water well "17 of section 3.

This base 1 portion is exteriorly' and tan"- a narrow horizontally'o'r 'trarisverselyelon- I gated slit-like outlet "or' relief; port "a, tangentially of the cylindrical nipple bore; Thisslit'con stit'utes a port communication from the lower end of the ccup interior through said bore 'to 'thelower end of the water well17'. f I

This slit port a is closed and*opened and its area or capacity is controlled by, a rotary plug valve 18 in the form of a cylinder having a tangential flat portion 18 extending through its upper'or inner end. This plug 18 extends longitudinally through the bore of the dash pot cup'nipple and'cl'osesthe sarne against water flow therethrough and leakage to the exterior from the lower or outer end of the bore. The plug extends to and'depends'at the exterior of the section 3' and is formed with exterior finger head 18* readily accessible to the fingers 'for rotation of the plug toset the same at the required mentary longitudinal A intermeshing screw threaded portions forming packing against water leakage, enabling the plug to be re-- moved, and rendering it possible to screw the plug-inwardly to a safe point to-prevent' leakage so that it may then berotated to:

adjust the passage and 'gauge'the length of time in which the

valves

5 and 6 are to remain open and thus regulate the required flush of water. The upper or inner cylindrical portion, excepting the flattened part 18,

of the plug fits the cylindrical inner surface of the nipple bore with a running fit so that the slit port a, will be operatively closed by the cylindrical surface of the plug, when the plug is turned or rotated to a position with the flat face 18, remote from the V-shaped slit port a. The flattened portion of the plug forms a longitudinal water. passage, within the nipple, that is open at its upper end into the dash pot cup and is otherwise closed against liquid escape or leakage, except when the flat portion 18*, is opposite slit port a, so that the portion of the nipple wall containing said slit forms a portion of the wall of said longitudinal water passage. When the plug is in this just mentioned position, fluid flow to and from the cup is established through said slit port and the nipple. By slightly rotating the plug, the slit port a, can be closed, or can be opened throughout its length, or can be fractionally opened to the extent required by the desired quantity of water to be discharged at each flushing operation.

The stem that controls the main and

relief valves

5, 6, is provided at its lower end with a piston 19 vertically movable in the dash pot cup 16, and this piston and the cup are relatively formed and constructed to cause inflow of flushing water into the cup under the piston on the opening movements of the main and relief valves, i. e. on the upward movement of the piston so that the cup will be full'of water before the piston starts on its downward movement. The upward movement of the piston also exerts suction pull through the slit port a, to draw water through said port and the nipple into the bottom of the cup. The piston and cup are also relatively formed to reduce to the mini mum water leakage or pressure relief from the cup during the downward movement of the piston, except through the slit port a.

It will be observed that the V or flaring form of the port a, provides sharp or feather edges forming the longitudinal walls of the port, whereby the inrush and outrush of water during the ascent and descent of the piston, will readily free the port from sediment or other foreign matter tending to clog or choke the same. These feather edges tend to prevent sediment and the like from collecting in and choking the port.

Various constructions can be provided for causing quick filling of the cup, although I show the piston provided with a flexible cup washer 19*, having .a depending annular flexible skirt formed to contract for water passage on the upward stroke of the piston and to expand against the inner surface of the cup and against upward passage of water on the downward movement of the piston. Also, if so desired, the internal diameter of the cup can be enlarged at the upper end of the cup to aid in such rapid filling of the cup with water under the piston. Also, some inflow of water to the cup through port a, from the water well, will take place during the upward stroke of the piston, while the speed of the descent of the piston and parts then carried thereby will be controlled by the outflow through and consequently by the area or capacity of the port a, which can be most accurately and readily varied or adjusted by plug 18. The valve stem 14 forms a stiff valve lifting and controlling rod-like member from the piston to the valves, and in the example shown is composed of two longitudinal alined sections removably united by longitudinal screw thread joint 14 for purposes of assembly and taking down, and if need be, to permit longitudinal shortening or extension of the lift stem.

Various means can be employed, operative from the exterior of the casing, for lifting the stem with the dash pot piston and the relief and main flushing valves to initiate the flushing flow, and for then releasing the stem so that the dash pot and piston can control the descent of the valves and the length of time of the flushing water flow.

However, I show improved and peculiarly advantageous means for this purpose. In the particular example illustrated, the casing section 2, is cast or otherwise formed at a point remote from outlet 2, with a hollow lateral bulge or offset 2", forming a lateral or side recess or chamber opening into the flushing water chamber of the section and otherwise closed against water outflow to the casing exterior. A vertically-swingable horizontally-disposed lifting member or lever 20, is fulcrumed in said bulge on transverse axis 21, and is arranged in the bulge and extends therefrom transversely across section 2, past the lifting stem 14 although I do not wish to so limit all features of my invention.

.The shaft pivot pin or axis 21, extends transversely across the bulge or offset 2, and is supported by the opposite vertical walls thereof, and, in the example shown, the outer end of the lever member 20, is formed with a transverse hub receiving and rotatable on the axis 21.

The lever member 20, is operatively connected with the lift stem 14 in any suitable manner or by any suitable means, to operate said stem to lift the flushing valves (main valve 5, and relief valve 6) to start the flushing operation. For instance, I show the free end of the lever member loosely crossing the lower section of stem 14, under a lifting shoulder 14", of the stem in such manner that when the lever member is rocked to elevate its free end, such end will strike said shoulder and through the medium thereof elevate the stem to lift the flushing valves. If so desired, the free end ofithe lever member can be longitudinally forked or bifurcated and thus loosely straddles the lifting stem below corresponding lateral downwardly-facing lifting shoulders 14, formed on" opposite sides of the stem, and above upwardly-facing lateral shoulders 14, correspondingly arranged on opposite sides of the stem. If so desired, these

shoulders

14, 14, can be of the approximate knife-edge type, and the stem can be flattened or reduced in thickness at its opposite sides between lifting shoulders 14 and depressing shoulders 14, although I do not wish to limit all features of my in vention to such connection between the lever member and the stem nor to the bifurcated and twin shoulder arrangement.

Suitable means are provided to operate the lever member to lift the flushing valves (first the relief valve, and then the main valve through the 'medium of the relief valve) to start the flushing operation by lifting engagement of the member with shoulders 14, and to then release said member, permitting its free end to drop to and rest on the stop or depressing shoulders 14.

In the example illustrated I show a thrust cam as means of actuating the lever member on its valve-lifting stroke, and then to permit the valve to close under action of gravity and the flushing water flow or pressure, whilethe speed of valve closing movement is controlled by the dash pot device. Such lever member operating vmeans, in this ex ample is mounted in and carried by the casing bulge or ofiset 2, and embodiesa vertical oscillatory spindle or shaft 22, extending from a point at the exterior of the casing to a point within the same, and extending through the top wall of the offset 2, and carried by 'androtatable in a suitable preferably removableplug in said wall forming a journal or hearing box for said spindle. At its upper end, at the exterior of the casing, said spindle is equipped with a lateral operating handle 23, normally fixed thereto. In the upper part of the chamber within the casing offset 2, the lower end of the spindle is formed with or carries a disk 24 fixed thereto and arranged centrally above the fulcrum of the lever member 20. The upper end or side of this disk provides an annular shoulder bearing against the top wall or closure of the casing offset to receive the up: ward thrust of the cam disk in action and limit upward movement of the spindle 22. The fulcrum hub of the lever member 20, is provided with a fixed stud or pin 20, projecting upwardly and outwardly therefrom at an angle, and a grooved roller 20, is mounted to revolve on said pin. v

Thedisk 24 is formed with a depending rounded thrust cam and trip nose or toe arranged a distance radially from the longitudinal axis of the disk 24 and its spindle and 'hence'e'ccentric with respect thereto and designed to engage and gradually depress the roller 20 and consequently swing the lever member on its valve lifting stroke, as the handle 23 is swung on an operative stroke, and to slip past said roller and free the lever member before said handle completes such stroke. This nose or toe is double to thus act on and slip past the roller, on each operative swing of the handle, i. e. when the handle is swung forward and when the handle is swung backward, referring to Fig. 9. This is provided for by limiting the back and forth swing of the handle to an are prescribed by stops 26 (Fig. 13) projecting inwardly from the vertical wall of the casing offset. 2, and cooperatingwith stop shoulders or a radial lug 24 rigid'with the disk. In this instance, the stop 24 is arranged at the outer side of and is centrally arranged with respect to the depending oppositely curved portions of the working or operative edge 24", of said depending toe or nose. The disk is formed with a depending edge track arranged above the roller 20, and this track embodies the elevated end portions 24, approximately concentric with the axis of the disk that gradually curve downwardly and converge to form the working edge 24 of the said nose or toe having acurved crown or tip toslip past the roller 'in'either direction. The working edge 24,is formed to ride on the grooved roller 20 and depress the same the maximum distance, say when the handle 23, reaches a position about mid way its stroke, see middle position shown by dotted lines Fig. 9, and the flushing water will continue to flow as the flushing valves are held elevated so longas the operator holds the handle in this middle position. However, if the operator does not hold the handle in this position, the curved cam nose will slip past the roller, thereby freeing the lever member after the flushing valves have been lifted their full .upward stroke permitting said member to drop by gravity onto the shoulders 14 leaving the member and the valves then entirely free and independent of the handle 23 and the thrust trip means. g

' The cam arrangement attains a powerful leverage action, by the application of but slight force to handle 23, to depress the short arm of the lever the shortdistance necessary to the relatively long full lift of the flushing valves through the long upward stroke of the long arm of the lever member, and vthe parts can be moved to cause a flushingoperation by'swinging the handle in, either direction from either stop 26 toward the other stop 26.

It is evident that various changes, modifications, and variations might be resorted to without departing from the spirit and scope of my invention and hence I do not wish to limit myself to the exact disclosures hereof.
