FLUBHING-VALVE.

Specification of Letters Patent.

BatentedDct. '3, 1911:

Application filed January 18, 1911. Serial No. 602,434.

To rt Z whom it may concern:

5'4 it known that I, JuLIUs S. JUDELL, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Flushing-Valves, of which the following is a specification.

My invention relates to improvements in flushing valves.

The objects of my invention are to rovide simple and reliable mechanism wiich will require no special form of packing for the actuating and regulating elements and which may be employed in connection with storage tanks. and operated successfully without reference to the sizeof the supply 1pc. I

In the following description,;reference is had to the accompanying drawings in Which,-- a a Figure 1 is a vertical sectional view of a flushing valve'embodyin one form of my invention. Fig. 2 is a si e view, part in sec tion, showin vention, an illustrating it as used in connection with a storage tank. Fig. 3 is a detail view of the manually actuated starting valve employed in Fig. 2.

Like parts are identified by the same reference characters throughout the several vlews.

In Fig. l'thevalve casing 1v is provided.

with an inlet 2 and outlet'3, andfisjsubdivided interiorly by a partition 4. The partition 4 has a removable member 6 pro vided with an opening 7 which is normally closed by a valve 8.

Below the art-ition, I provide a cup shaped member 9w ich receives a iston 10 and this piston is connected wit the valve 8 by alstem IL A duct lo connects the dug if space below piston 10 with the outlet'3, an

fa set screw 16 is employedto re late the ,fl'ow of liquid frol'n'the cup to t eoutlet; This ductand set screw are of the ordinary \t" e emiployed in flushing valves to estab: 11s ax: o sing interval, except that-I have provided an elbow at a into which the amt of the set screw enters, onthe axis 0 one arm ofathe elbow. With this arrangement the set-screw may serve as a needl valve,

providing eflicient means for regulating the I removable cap 30wh1ch afl'ords access to the time interval. I a a II The cup member 9 ma. receive water through a duct20, connects with the sup 1y I water of the casing inlet 2 at any suita 1e another embodiment of my 'inleather to seat slight leaka e may result, but it will doing no material damp I fore notbe found'essentra to pack the valve point. In the construction shown in Fig. 1, I extend this duct horizontally to the side Wall of the casing 1 and then upwardly in a rib or thickened portion of the sidewall to a point above the partition 4. The up er cm .of the duct 20 is closed, but a slide va ve 21 is mounted in an aperture in the side wall of the casing in a position crossing the duct. This slide valve is one of the important features of my invention in that its construction, as well as its relation to the duct 20, provides efi'ective means for preventing leakage when the valve becomes worn or the pa'clring' defective. The valve 21 forms a ortion of a member havin in eneral, the orm of an ordinar bolt extendmg through the casing wall wit 'a head 22 on the outer end, formingan actuating, knob, and a nut 23 on the inner end, which is referably locked by any suitable means a ter being roperly adjusted. The portion of the memer which constitutes the valve is provided with a longitudinal groove 6, preferably terminatin at its-outer. end, in an, annular groove A collar 25 on the valve member is socketed in the casing-wall, with a coiled spring 26 bearing upon 1ts inner face, which tends to hold the valve in closed 'osition.

When pushed inwardly to the position illus-.

trated in Fi 1, the valve oove b ,will receive water. rom the interior of theca'sing 1 and deliver it through the groove d to the ;duct 20. When released, the valve member is moved outwardl by the reaction of spring 26,, until groove I is covered by the casing Wall and the inner end of groove 6 is'covered b the projection 28 on such veal]. As'

an ad itional security against leaka the inner surface of projection 28 is fac ofi to receive thenut'28" which serves as a valve,

and is preferably provided with a non-ma tallic covering 29 preferably rubber or ainst said projection 28, Notwithstandin t ese features, there is still a possibility at, with continued use, 'a I I beobserved thatt rearrangement is such that the leaka water will be received bly the duct 20 an% pass to outletthrough duct 15, thus It will' therememher either in the'casing wall or n the spring socket A screw cup 82. covers the inner end of the valve, ,V s The operation of the'davlce will be apparthe supply water,

,ent from the above description. When the v move to closing position, the water in on 9 is slowly delivered through duct 15 an the piston and valve 8 move downwardlg by gravity, and under the pressure of the o lng water until valve 8 closes. During this downward movement of the main or piston actuated valve, considerable pressure 1s eitcrted upon the water underneath the piston, but by arranging the starting valve member 21 so that itwill out 01f communication between the duct and the inner face of the valve nut 23, said back pressure is expasses, said valve 21 servin erted merely a. ainst the cylindrical side of the starting va ve member 21, instead of,being permitted to enter the groove 6 in said to ve, which valve 23.- It will result is secured by fit the walls through w be understood that this havin member 21 closely ich the duct 20 as a slide valve,

I which, .under ordinary c'on itions, would be effective for the accomplishment of my purposes, independently of the nut valve 23. ,This slide valve not only fits,the walls of the opening occupied by It on the inner side of the duct 20, but also fits said walls closely on the outer side of said duct, and when the valve is closed, the annular roove d dogs ister with the duct 20 or duct 51 n not re Fig.3

, eferring to Fig. 2 it will be observed that a closed reservoir 35 is provided with the .valve-bya stem 11, spending parts shownm .lower portion of a'valve 8,cup 9 and piston 10 connected to all like the corre- 37 depending from the reservoir The casing 37 corresponds with the the casing 1, in Fig. 1,

I and the reservoir 35 corresponds with the a ,Qulpper' portion of the casing 1 above parti- T tion 4 In-Fig; 1, said reservoir 35 being empo'intj t loyed to store water when the supply pipe r all, In thisconstruction it Is necessary q rovide for air admission to the reservoir 7 iiiorder, to-allo'w the water'to. discharge; .Th' 's accomplished by a duct" or pipe extending from the. outlet pipe 46 to the .upper ortion of tIlIG'I'BSGI'VOII, at which epipe' 45 1s rovided with a U-, shaped bend 47, 'an i the down-turned extremity carries a float valve 49 which,

when the water level drops, hangs. suspended from the pipe 45 by a headed stem would convey it to the nut.

" stem 64, andin F g.

h Fig.1,and located 50. The piston 10 is actuated, in the construction shown in Fi 2, in the same manner as in Fig. 1, but the starting valve 21 is located at a greater distance from the cup 9, and the duct 20 is extended to the valve 21, preferably in the form of a pipe 51 within the reservoir. The valve 21 is shown in section in Fig. 3 and is the same in structure as in Fig. 1, but is located in a removable fittin .53, which takes the lace of the casing we in Fig. 1, and with w 1011 fitting, pipe 51 connects. The valve 21 is shown in closed position in Fi 3.

In the operation 01 this device, valve 21 is opened and piston 10 lifted by'water pressure from the reservoir to open valve 8. As the water in the reservoir drops, the float valve opens and air enters from the outlet, thus permitting a delivery of all'the water from the reservoir if valve 8 remains open long enou b. When valve 8 closes, the reservoir rolls from inlet ipe 56 until the water strikes the float valve 49, the reservoir air passing to the outlet pipe 46. Float valve49 is then lifted by the. water to close the pipe 45, after which the remainin air in the reservoir will be compressed until its resistance prevents a further entry of water. This residual airre-expands when valve 8 is a ain opened, thus preventin a vacuum unti the water'level has droppe suflicient-l to ermit float valve 49 to a sin open. we1ght' .60 is preferably emp loyed for the valve 8. In most cases this will not be found essential, although desirable for small valves. It will beobserved that the cup, or cup shaped socket 9 is supported inthe casing;

by a transverse member 62 in which the duct 15 and the lower portion of the duct 20 extend, and in which also the screw 16 is mounted, thewater passing downwardly on each side of this member through 0. enin indicated in Fig. 1, by dotted lines. in Fi 1, the valve has an upwardly extending guide 2 a spider frame 65 serves as a guide. e valved duct 45 may of course be employed in the structure shown. in Fig. 1, if desired.
