I FLUSHING-VALVE Application filed March 16, 1926. Serial-No. 95,007,,"

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate several embodiments of the same,

selected by me for purposes of illustration, and the said invention is fully'disclose'd in the following description and claims.

The object of my invention is to provide a flushing tank and mechanism for water closets having the maximum efficiency combined with extreme simplicity and cheapness of manufacture,'and so constructed and arranged that all necessary repairs and replacements can be made by the householder or any unskilled person, without the ex- .pense and delay incident to the employment of skilled labor, my invention being capa ble, as illustrated in the forms and embodiments thereof herein shown and described, of being readily employed in practically any of the ordinary flush tanks now in use for the purpose of repairing or refitting the same. A a

One of the important features of my in vent-ion is that Idispense with the ordinary afterfill tube usually employed in flush tanks for the purpose of refilling the bowl and insuring the sealing of the water seal, after a flushing operation has taken place.

charged over the sides of the tank on the bathroom floor, and often occasioning ex pensive repairs in the apartments below. According to my invention the pivoted float- ,lever, or float, is provided with a depending flexible device, normally suspended above and out of line with the flushing valve seat, but insuch position that as the float descends during a flushing operation, this depending flexible device will be car ried by the currents of water into the flushing valve "aperture and over the flushing valve seat, so that when the flushing valve seats. it will be held in slightly open positubes frequently become eaten tion by such'depending flexible device, pervalve to close completely as the flushing tank is filled to its normal level. The dura tion of the afterfill can be readily deter mined'by the adjustmentof the depending flexible device, either'by adjustingits length or its positionwithrespect tovthe pivotal Y axis of the float lever, or both, and in connection therewith I prefer to employ a hollow valve of flexible rubber so that when it seats on the flexible depending device, as before stated, which is preferably a chain of non-corrosive metal, the flexiblewall of the valve will be somewhat indented, and will prevent a too great,afterfill aperturebe-ingprovided, although substantiallyfthe' same effect can be obtained by employing a @181; pending flexible device of the requisite dia-Ineter.

According tomy invention, I also provide an overflow pipe which is connected to the valve and communicates with a passage,

. or passages, extendingthrough the valve so that the overflow pipe forms [the valve i stem, and the use of an eccentrically located overflow pipe is avoided, and the connection of suchanoverflow pipe with the flushing o'utletbelow the valve seat, usuahin flush tanks, is avoided, thus simplifying the construction of the flushing outlet and avoiding the use of screw threads. Simple and inexpensive means are also provided for preventing the valve from getting out of alignment with the flushing outlet and the valve, and parts attached thereto are adjustablyconnected with the valve operating mechanism in such manner that the weight of the valve and parts connected therewith, including the overflow pipe, i

substantially counterbalanced, so long as 95 the valve remains submerged in the water i in the tank, but as soon as the valve is re lieved from the supporting effect of the surrounding water, the weight, of the valve and its connected parts will overcomethe l weight of the counterbalanced portion of the operating devices, and the valve, will fall bygravity uponits seat. In carrying out this feature ofmy invention, I prefer to make the valve in cup shape, sothat when in use, it will normally 'be and remain filled, with water, which has no effect when the valve -isentirely surrounded by water,

but which acts as a weightas soon as the water recedes below the level of the lifted' va lve.- a g My invention also includes other novel of my invention, selected by me for pur poses .of illustration. j

In thcembodiment of my invention illustrated in Figs. 1, 2 and 3, I have shown a form which is not only desirable foruse in the equipment of flushingtanks in an original installation,but which can also be used advantageously in repairing or refitting tanks now in use. In these figures the tank, 1, itself is shown in section looking toward tie front wall. These flushtanksare usuall made of porcelain and providedwith a cover, indicated at 2 but it is immaterial as to the particular composition of the tank wall, as the form and size of'flushing tanks are approximately the same regardless of the materia-lof which they are constructed. f It is also customary toprovlde the front wall of the tank, acent to the upper corner at the left (when the tank is v ewed from the front), with an aperture through which the valve operating mechanism extends and the bottom of the tank is provided approximatec'entrally with an aperture, 3, which receives the fltting'connecting it wit-h the flush ing pipe, 4, leading to the bowl, 5, in any usual or desired manner., I have shown the; bottom aperture, 3, provided with a metallic sleeve, indicated at 6, which may be provided with a valve seat, as indicated at 7, and a, lateral flange, S, onits upper end between which and the bottom of the tank is located a rubber or other suitable packing washer, 9. This sleeve, 6, 1s eitteriorly threaded and is also n'ovided, internallv with aro'ections 10, conveniently formed by indenting" the sleeve before it'is threaded, so that the sleeve can be held against rotation in the aperture,

.3, while the securing nut, indicated at 11, is

menses the sleeve may be employed either with or ceptarle, 1 6 between "the sleeve, 15, and the outer walls of the valve. The bottom por tion of the. valve at this extreme end is provided with one or more apertures, indicated at 17., communicating with the-interior of the sleeve, but not communicating with the Water compartment, 16,-and these apertures,

17, serve as the ultimate discharge apertures for the overflow pipe. The extreme bottom portion of the valve, which is connected with the side walls of the valve the strips of rubber between adjacent apertures, '17, is

provided with an aperture, indicated at 18,

to receive a depending auxiliary stem, 19. This may be tor-med of metal, but is more conveniently for-med of wood, coated with asphaltum or other sealing material, which will render it impervious to water, and this makes a very cheap, and at the sam'etime, efiic'i'ent device. "The auxiliary stem, 19, is simply inserted in the opening, '18, in the bottom of the valve, and retained therein by friction. '20 represents an overflow pipe, which also forms-the valve stem of the flushing valve. This pipe is preferably formed of hard rubber orother suit-- able material, which is very light. I may employ aluminum or-cellu'loid, or other suitable material, if preferred. Th-isoverfiow tube is of considerable diameter, is open at both ends, being ordinarily tor-med by cutting-01f the required length froma stock tube, and the lower "end fits within the elastic sleeve, 15, of the valve, an-d is held united thereto by friction, or it may be cemented or secured in any other manner ifnecessary but ordinarily the frictional engagement -'0 the sleeve of the exterior of the tube will be sufiicie-nt. The upper end of the tube, 20, is provided with overflow apertures, inclicate'd at 21, and I prefer to provide the extr-eme end of the tube with a cap, 22, shown in detail in Figs. 5 and '6. This cap comprises a circular disc or plate, substantially of thev same diameter as the disc or tube, provided with guiding projections, 23, 24, engaging the exterior of the tube. Two op- .positeprojections, as, 2%,are of suliicient' length to extend below the upper edge of the adjacent overflow aperture, 21, and are provided each with an inwardly turned flange, indicated at 25, in Fig. 5, which engages the upper edge of the said aperture, and holds the cup firmly on the end of the tube. The cap, 22, is provided with means for adjustably engaginga flexible :connection, as a chain, for example, indicated at 30. In order to allow ror the adjustment of this chain with respect. to the tube, 20,

.I- prefer to provide the :cap with Ian eccentrically located aperture, 26,'lhamng a nar r'oav slot, '27., c'oinmunicatin g therewith and extending to the central part oi the to enough to accommodate a portion of one of J the links, so that the adjustment of the chain with respect tof-the ca can'be readily ef-' 'iected. The upper en of the tube, 2 0,' is also preferably provided with a butter, for which purpose I conveniently employ a 'd-isc,-28, of rubber, or other elastic material ivlri'ch 'is provided with "a central hole, '28, through which the chain, 30, p-asses a:nd also prefer to provide the lower face of the disc, .28, with integralprojections, 28*, one of which is adapted to nationally engage the aperture, 2'6, "-in the cap, andft'he ether of which engages similarly another apeia tu-re,"20, in the plate, preferably on the opposite side of the center of the cap through the aperture, 2'6,"so*tih at after the chain is adjusted, which {can be accomplished by simply liiting'v the rubber disc, 28, far enough to disengage the projections, 28", from. the apertures in the plate, as indicated in Fig.v '6, it be positively retained in its adjusted relation with the tube, 20, by

restoring the discto position'with the pic j-ections, 28 in engagement with the apertures in the plate, as shown Fig. In Figs. 1, 2 and 3, I have sho-wnvalve operating mechanism, of which the main element is a pivot-ed lever operated by 'an oscill'ating handle shown in dotted lines in these figures, are well known way, and in connection therewith I have illustrated a supporting bracket adapted to be secured to the tank, and which may beused either with this type of operating means, or in connection a'pull chain operating means, as illustrated in 'Figs. 7 and 8, hereinafter described. While this bracket may be formed oi castmetaLI find it convenient to tormitof sheet metal by stamping process on account of the cheapne'ss. This bracket lispreferablyycomposed of a vertical we'byor plate, 31, provided at one end with an aperture "engaged by theusual bearing sleeve, indicated at '32, extending through-the usual aperture in the, front face of the tank, and provided with the nut, 33', which clamps the bracket firmly against the inner face of the front wall of the tank. Where the device is madeof sheet metal, I prefer to provide its lower edge with a horizontal stiiieni'ng flange, indicated at 3a, and the outer end of the bracket is provided witha slot, 35,- adapted to be engagedby a bolt-,36. which secures a grooved support, 37, formed preferably of porcelain,

on account. of its almost frictionless surface, andthe fact that itis not liable to corrosion, although it may be formed of other material. This support is grooved to enable the chain or flexible connection, 30, extending through the tube, 20, to slide freely with the minimum of friction over it and to guide it in its movement, The inner end of the bracket is bent inwardly and may be put in a vise and given a greater inward bend when required, so as to bring the groove in the sup port, 37, substantially in alignment with the axis of the flushing valve seat, and the slot, 35, is provided so-that the support may be adjusted longitudinally of the bracket to bring the outer edge of the grooved portion of the support directly and accurately in vertical alignment with the axis of the flushing valve seat, and to compensate for slight variations in the distance between the axis of the valve seat and the axis of the hole in the front wall of the tank,which may occur in existing tanks. To enable the bracket, 7 to be used in connection with the pull chain type ofoperating means, it is also provided adjacent to the aperture through which the bearing sleeve, 32, passes, with a horizontal supportingflange, indicated at 38, which is provided with a, threaded aperture, hereinafter referred to, and which flange is so located as to form a'stop to limit the, re

turn movement of the operating lever and prevent any movement thereof in the wrong direction. The operating lever ltself is shown in detail in Fig. 9, and comprises a bearing shaft portion, 39, which extends throughthe bearing sleeve, 32, and is pro vided at the'outer end with the operating handle, indicated in dottedlines, at 40, and which is provided within the tank with an inclined portion, ll, adapted to'engage the edge of the flange, 38, the position of which is indicated in dotted lines in Fig. 9, so as to limit the movement of the handle and lever in one direction, the portion, 41, being provided with an angularly disposed arm, 42, to which the flexible connection, 30, is connected in any usual or desired manner. The .lev r, 12, chain, .30, overfiowsleeve, 20, and the flushing valve, 14, are so counterbalanced with respect to the grooved support, that the flushing valve will remain in any position torwhichit is moved, so long as it is submerged, at which time the'water in the annular compartment, 16, of the valve, does nottend to effect the downward movenient of the valve. 'This counterbalancing may be effected in any desired way, by makin the arts of the V roaer wei 'htof mate-- t1 1 l. i:

Figures 7 and 8 illustrate a slight modification of my invention, by which it can be readily adapted to the pull chain type, if this is desired. 7 7 shown thebearing sleeve, indicated at 132, provided with a central apertureof sufficient size to permit the free passage of the chain, 130, therethrough, the outer end of the said aperture being flared so as to permit the free movement of the chain. The bearing sleeve is provided with the usual head at the outer end over which is slipped a slotted portion of a hood, indicated 1 16, which maybe of porcelain, or metal, andfgives a neat finish to the exterior. The bearing sleeve, 132,

passes throughthe bracket, indicated at 131,

and is provided witha nut, 133, which secures both the bracket and the hood in place. The bracket is constructed exactly as previously described with reference to l igs. 1, 2, and 3, and is provided at its outer end with the adjustably curved support, 137, for the chain, which will be adjusted in thesame manner as previously described. The hori- Zontal supporting. flange,'138, of the bracket is in this instance provided with a horizontally disposed grooved guide, preferably in the form of a roller, 14?, which is preferably made of porcelainso' as toinsure the free passage of the chain. The chain, 130, passes over the support, 137, around the roller,.1el-7, and out through the sleeve, 132, the exterior depending portion being pro-;' vided with a counter-balance and handle,1-l0. The handle and exterior depending portion of the chain may be of such'weight as to properly counter-balance the overflow pipe in the valve, and the interior depending portion of the chain, and in some instances I may provide a hollow handlewith a removable cap, indicated at 140", as shown in '8, for example, in which small bullcts' of lead, or other suitable weights can be placed to effect the desired counterbalancing, or an additional length of chain may be inter-. posed between the sleeve, 132, and the handle,

in the present instance 1 have shown the tank provided with a water inlet pipe, indie cated at 50, inFigs. 1-, 2 and-3, supported by a connection, 51, in thisinstancein the bottom of the tank, and'extending vertically In this instance I have.

therefrom, said connection being united with the water main by ,a pipe, indicated at 52.' The upper end of the water inlet pipe, 50, is provided with inlet valve indicated at 513,, the detailed constructionof which'is not claimed herein and need not be specifically described. I

In the present embodiment of my inventionl have illustrated a float, lever, 70, connected with the inlet valve, 53, and provided with a float, indicated at 71, which is preferably formed of a, block of compressed granulated cork, or small pieces of waste cork, held together by a suitable cementitious material, and given an exterior coating. of

Waterproof material, which permeates suf ficiently into the interstices of the block to prevent thepossibility of any .water entering, and therefore insuring that the cork float shall retain its originalspecific gravity and buoyancy during its immersion, or partial immersion in the water. Floats, for flush tanks are usually made, of spun metal in spherical form, and are liable to become damaged in shipment, and are alsoliable tobecome corroded and eaten. through in use,

.so. that they frequently fill with water and 7 become useless.

They; are l expensive and there. is. a considerable loss attending their use; My improved float is preferably made bytaking a block of cork composition, that is to say, compressed cork particles, united by cementitious materiahfand impregnating and coating the block with asphaltuin residue obtained in the distillation of petroleumhaving'an asphaltum base, thus producing a very cheap and eflicient' float. In impregnat ing'the blocks I prefer to first exhaust the airtheref rom, by enclosing them in a vacuum chamber, afterv which. the asphaltum residue is admitted. in liquid form, sothat it isforced to aconsiderable extent intohthe interior of the blocks, in addition to. thoroughly coating the. exterior, and when this asphaltum r esi-; due becomes. dry and hard, the composition cork block is perfectly protected against the water in the tank, The shape oftheblock is, immaterial, but. I preferably make it in the form ofa block or briquette, which gives the desired buoyancy without any additional expense, b,ut they may be made in other forms,

if des red. 'In order to attach the float to. the float lever, 70, I may thread the extreme end of the said lever, as indicated at 72, the

, extremity of whieh'is preferably sharpened tofa point,'as indicated at 73, itIldrPfOVl'ClB the float with a threaded clip, shown in, detail in Fig. .11, which may be conveniently formed by bending-a sheet of, brass or other non-corrodible-metal around. a. mandrel,v tofform sleeve. portion,74, the ends being brought together,. as indicated at 75,. and the; sleeve being subsequently threaded, This clip may bedriven into one end. ofthe block, either before or after, coating, and by this means the lever, 7 can readilybe. screwed into the end of the clip, as, indicated in Fig. lOJ

This, however, is not strictly necessary, and in some instances, I may form thelend of thelever, '70, as a smooth unthreaded rod, having a point, 73, on its cxtre1nity ,.to enable. it to be driven or forced into the block in. any de-. sired position, as indicated in full and? dotted 5 lines in Fig. 12. By inserting the lever-,ZO,

in thefloat atd-iflerent positions,.or in dif i ferentangular positions, the desiredwater level in the tank may be regulated without 1 bending the float lever.

According to my present invention, I also provide the float lever withadepending flexible device, preferably a ball chain,; ins dicated $3,763, which maybe attached either to the float or the lever, and which ispref-' erably adjustable both as to length and, asto; the distance from the vertical axis of the flushing outlet. In Figs. 1, 2, v 3, 10,11 and 12, I have shownthe float lever, 70;,provided with a flattened portion, 77, in which are! formed a series of holes, 78, toyireceive; the depending afterfill device, 76, which is.p.ref-.

'erably in the form of a ball chain..1 By

making these holes substantially'the, same.

size as the exterior of the balls of the chain, f the vertical adjustment of the chain to a ly.

desired length below I the lever can be, readily accomplished, by i simply ulling-" the chain through one of these apertures inthe manner indicated in Fig. 13, and lettingthe unused end hang fromthe 'lever. This, puts a sufiicient kink .inv the chain so asto lock the chain with respect tothe lever in its adjusted vice is so arranged that it will normally hang slightly at one side of, the. inlet valve and flushingv outlet when the lever, 70', is in raised position, so as not to interfere with the operation ofthevalve, and to; prevent the possibility of its getting into-the annular compartment, 16, of, the valve,f:and altering the balance between the valve and I its operating mechanism, before described n th flughingfvalve, is raised and" the;

flushing action takes place, the float lever and float will descend, and the rush of water.

to the outlet in the bottom of thertank will sweepthelowerendof the chain, 76, down 7 into the outlet, in the'manner indicated in Fig. 2, so that whenthe valve seats, as indicated in Fig. 3, it will engage this chain,

7 6 (or other flexible device)i,. and, hold the.-

valve slightly offiof its seat, the fiexi'blewalls of the valve, 14, which I prefer to use, flexing somewhat, so as to leave a comparatively small Opening when the valve'is thus heldv oil of its seat, As the float descends, the

inlet valve opens, admitting water to the,

tank, and as soon as the valve is partially seated on the chain, 7 6, the water level in the tank begins torise and the eilect of the chain, .76, is to permit a small quantity of water to be discharged through the flushing outlet to effect the afterfill, so long as'any portion'of'the chain remainsbetween the valve and seat. As the water level rises, the buoyancy of the float will gradually withdraw this chain, 76, until it is finally pulled clearof the valve, permitting the valve to completely seat and shut off the water from 7 the flushing outlet, and by regulating the length of the chain, 76, the duration of the 7 ing the chain with respect to the staple, it

a'fterfill can be accurately regulated. This enables me to dispense with. the ordinary afterfill' tube, which, as before stated, is very apt to become corroded and broken, and

there'is no danger of water being discharged through an afteiiill aperture to the exterior of the tank, as often happens where an the afterfill device, 176,"secured directly to the float by astaple, 178. By pressing thisstaple into the float at'diflercnt positions along the inclined face 171 and by adjustwill be readily seen that the chain, 176, can be adjusted as to length and also can be adjusted laterally with respect to the axis of'the flushing aperture. I 7

It will be seen that, in carrying out "my invention I have provided a flushing apparatus of the utmost simplicity which can be readily installed in a tank made for it or in any of the ordinary tanks now in use,

so that it can be furnished as a complete equipment, or as a repair equipment for an existent installed tank. When it is installed, it can be readily adjusted as to all its componentqparts, to accommodate dit' i'erentwater pressures, the desired level of 'Y'water in the tank, and other variations which may be encountered, and when once adJUSiZed, it is practically foolproof.

separate parts can be readily furnished for :efl'ecting' repairs, if they becomenccessary,

and anyrepairs or replacements can be made by any householder or unskilled person, without the use of either tools or skilled labor.' For exainple, in case a new valve .isto beinstalled, the householder can take hold of the upper end of'the tube, 20, and

The

lift the tube and valve over the side of the tank, the chain, 30, (or 131), providing sulficient length to enable this to be done, so that the old valve can be slipped off of the tube, 20, a new valve applied to the tube, and the parts replaced. The inlet valve can be replaced when necessary by any one without even wetting the fingers as the parts are all above the level of the water in the tank. If a shorter overflow pipe is desired, it is only necessary to cut off a portion of the lower end of the tube, 20, before inserting it in the sleeve, 15, of the valve, to ob-tainthe desired distance between the valve seat and the overflow apertures, 21. This distance can be increased by merely'withdrawing the tube and valve, and partially withdrawing the tube from the sleeve, 15, of the valve, and the correct operative length of the chain, 30,

'(or 130.) can be readily secured by the adjusting means previously described'in connection with the sleeve, 20.

It is also to be noted that, as the overflow tube is secured frictionally to the valve, it may be made of very thin material, as there will be nothreads to weaken it, and there is no danger of" its becoming broken or corroded in use. action with a tank provided with my inven tion it is only necessary to raise the flushing valve off of its seat, by operating the lever shown in Figs. 1, 2 and 3, for pulling the exterior depending chain, in the form shown in Fig. 7. The upward movement of the valve will be limited by the engagement of the buffer, 28, with the stiffening flange, 34, of the supporting bracket,31, which will arrest the upward movement of the valve noiselessly. It is not necessary to hold the lever or pull chain as the parts are counterbalanced so long asthe'valve is submerged, and the water will immediately flow out of the flushing outlet to the bowl to efl'ect the flushing action, the float lever descending with the fall of the water level 'in the tank.

As soon as the depending afterfill device reaches the bottom of the tank, it will be swept bythewater into the flushing outlet and will engage a portion of the valve seat. The lowering of the float. lever also permits the inlet valve to open and allows water .to flow into the tank, but obviously not'so rapidly as it is flowing out. When the water level descends below the flushing V 120 valve, so as to! relieve the'valve of its support, the valve will descend upon its seat, but will be prevented from completely seating by the a-fterfill device. This permits a small quantity or" water to be discharged into the flushing pipe, to 'eifect the afterfill,

To effect the flushing i is as before described, during the refilling of.

the tank. As the float lever rises, with the water level, the afterfill device is drawn up ward until it is withdrawn from between the flushing valve and its seat, permitting mariner,

the valve to seat'co-mpletely and shut off a further supply of water to the bowl, and" as the float rises, to its normal position, the inlet valve is closed and the admissionofi water to; the tank ceases, the parts beingin position for another operation. I

It; is also to be noted that inmyflushing mechanism, the float and float lever affect both the inlet valve which it controls,'and the outlet or flushing valve, which is held open for a predetermined period during the refilling of the tank to effect the afterfill, and therefore cooperates with both the inlet and outlet of the tank.
