VALVE Filed Deaf 29, 1930 Suunto@ HLANDU E. fri/BER- Patented Mar. I4, 1933 ORLANDO B. HUBER, or MILWAUKEE, WIscoNsIN y VALVEl Application le December 29, 17930. Serial No. 315,324.1

f This invention relatesfto plumbing fixtures and more particularly to valves and actuating means therefor. v f Numerous types of valves vhave been incorporated in plumbing fixtures and varying measures of successful operation have been attained. Mostftypes have functioned satisfactorily for a short time andthenbecome leaky and ineffective due to wear, misalignment, for faulty functioning of the actuating mechanism. y

One object of the present invention is toV overcome the above mentioned defects by providing a hollow expansible valve which will retain its effectiveness for an indefinite period ofvtime. l e

Another object is the provision in a plumbing fixture of a' flexible connection between the valve and its actuating mechanism. f

prove the construction of devices ofthis character by materially reducing their costand increasing their life and effectiveness.

Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention. In the drawing: f Figure 1V is a vertical sectional view through a plumbing fixture showing a valve constructed in accordance with the teachings of the present invention togetherwithactuating means therefor. f

Figure 2 is a sectional view taken on theline 2 2v of Figure l.

Figure 3 is a vertical sectionalv view through the valve and actuating means taken at right angles to the showing in Figure 1.

Figure 4 is a view similar to Figure 3 showing a modified form of the valve.

The plumbing fixturev selected for illustrating the `valve and actuating means therefor comprises anoverflow pipe 10 provided at its lower extremity with a usual T-fitting 11. Anvelbow 12 is retained on the upper extremity of thepipe 10 `in the usual manner and registers with an overflow opening in thewall 13 of the tub. The elbow 1 2 is provided with ausual flange portion 14 adapted to surround the overflow opening and bear against the wall of the tub. Aring 15 is adapted to be A further object is to simplify and im-- passed through4 the overflow opening of the tub and engage an internally threaded portion of theelbow 12. `A flangel formed on thering serves to engage the inner wall of 1 the tub to retain Athe elbow in desired posi- 5 5v tion and also serves as a means to 'which an escutcheon 17. may be securedbymeans of screws 18. The escutcheon is provided with` the usual water drainage openings 19. .The i i i escutcheon is provided with a usual" central- Q ly disposedvertical slot 20,through whicha valve actuating lever 21 may be inserted and manipulated in amannerto b ehereinafter.,` more specifically described. f l

The T-itting 1 1 is provided -witha'long- 65. tudinal; bore which forms a valve,vchamber 22. Thischamber 22 is Vinopen communication with the .lower extremity. of the fittingwhich is adapted to receive lthe discharge or soil pipe. (not shown).-` VThehorizontal arml Y of thegfitting 11 is threaded in the usual I'nan-I ner t0 receive the drainpipe. (not shown)` which leads from the waste opening of the tub. Apassage 23 in the horizontal-arm ofy the fitting leads to thevalve chamberA 22 and 75 communication between the drain pipe vand soil pipe is controlled by avalve 24.

Thevalve 24 comprises a hollowcylindrical lmember 25 longitudinally 'split to make expansible to effect a sealing contact with the wall of the valve chamber `22. A coil spring26 is transversely disposed within the hollowcylindrical valve 24 to normallytend to spread themember 25 to insure sealing contact with the wall of thevalve chamber. `-This g5 coil spring 26.is fastenedtothe inner wall of theyvalve 24 in any approved manner.` In Figure .3 of the drawing the connection is effected by the use of soldenv A modified form of spring mounting is shown in Figure 4 and will hereinafter b e more specificallydescribed. The coil spring 26serves a dual purpose of maintaining the expansible valve. in contact with the wall of they chamber and also to provide a flexible means upon Awhich the valve actuating mechanism may 1 bel mounted. The Yvalve actuating mechanism` comprises afitting 27 provided with abore 28 for receiving the spring26 prior to its application 10Q to thevalve 24. An extendedportionv 29 of the fitting is provided with ascrewthreaded bore 30 adapted to receive the threaded end ofaconnector link 31. A suitable lock nut, carried on thelink 31, serves to effect a locking connection when the parts have been ad'- justed to ythe desired position. The upper end of thelink 31 is pivotally mounted uponapin 32 carried on the inner end of the actuating lever v21. The lever 21 is rockably mounted on apin 33 which is positioned in theears 34 on the escutcheon 17. Asuitable operating handle 35 is retained on the outer extremity of the lever 21.l 4

A brief description of the operation of the valveactuating means will serve to illustrate the simplicity andthe positive Voperation ofv Lthe valve. As thehandle 35 is drawn downwardly, the lever 21 Vis rocked upon thepin 33 and the valvey 24 Vis raised throughthel action o f-thelink 31 and the fitting 27 which is mounted upon `thecoil spring 26. As thevalve 24 is raised communication between the l drain pip'eof the tub and the discharge or soilr pipe is established to thereby drain the water from the tub. The valve may be closed merely by raising thehandle 35 until the lower extremity of thevalve 24 contacts with the inwardly directedflange 36 which is formed at the lower end of the valve chamber 22.V

yIt will be noted'at thistime that the construction `of the valve is such that avirtually unimpeded passage is provided for the free passage of water from the overflow Apipe to the discharge" pipe at all times by reason Vof the hollow formation of thevalve 24. It

will also be noted that the entire valve and actuating mechanism may readily be withdrawn from the fixture through theoverflow pipe 10 merely by removing the escutcheon 17.

Thevalve 24 shown in Figure 4 of the drawing is similar in many respects tothat v illustrated in Figs. 2 and 3 and comprises avmember 25, a coil spring 26', a fitting 27 abore 28 `for receiving thecoil spring 26, an extendedportion 29 on the fitting and alink 31 adjustably connected tothe valve in the manner previously described. The modification in vconstruction liesy in the mounting means for thespring 26. VIn the Vpresent instance themember 25 is provided with threaded 'holes 37 adapted to receivestuds 37 whichextend into the ends of thecoil spring 26.Collars 38 are positioned upon the inner wall of themember 25 `in such a manner that their inwardly directedflanges 39 actually enter into enlargedends 40 formed at the i ends of the bore 28.Y By reason of this construction itis possible to build up small valve f mechanisms embodying all of the advantages reason of their becoming misshapen. In the construction illustrated in Figure 4 it will be apparent that virtually no strain is placed upon thespring 26. Theflanges 39 contact with theends 40 of the fitting surrounding the `bore 28 to take the strain of valve motion.

It will readilyfbjeseen from the foregoing that a simple, inexpensive, and effective valve has been provided which will overcome the dimculties common `in present types of plumbing fixtures. While the valve shown and described is designed primarily. for operation by longitudinal displacement, it is quite obvious that a rotatable valve might well be substituted therefor. vA port inthe valve membercould be provided so that the functioning of the rotatable valve would 'bef While the device has'been described in con-.-Y

siderable detail, various changes may .be made in its embodiment without departing from or sacrificing the advantages of the invention as defined in the appended claims. v
