n This invention relates to waste and overn flow valve mechanism for" bath tubs, wash basinsl andthe like of the type in which a valve seat is located in the T-fittin r to which the bottom waste pipe, the over ow wastev pipe and the soil pipe are connected, the control valve, which is normally located in the chamber of said T-tting, being Operated through linkage located 'in the overflow waste pipe by means of a leverpivoted sona cover or screen secured over the overflow opening of the bath.
' Heretofore. this valve mechanism has usuallyemployed a'tubular valve, which while shutting off the bottom waste assage, permits any water from the over ow waste to pass therethrough.
These tubular valves are difficult to maintain in a tight condition and further the operating mechanism has been such that ,it 1s' necessary in bath rooms of limited dimensions to provide special means for getting at the waste ipes to disconnect before any repairs or a j ustment may be made in the valve mechanism.
My object, therefore is to devise valve mechanism in which a solid valve may be employed While permitting roper escape of excess water in the event o the supply tap being left-on too long, andparticularly'my object is to devise a construction in which the valve and its operating means ma be withdrawn for adJustment without aving to disconnect the waste ipes in any way.
I attain my objects y means of constructions which may be briefly described as follows. A. waste pipe from the bottom of the bath tub communlcates with a vertical over flow pipe located within the usual overflow Waste pipe. A plug valve controls an outlet to the vertical waste pipe from the overflow pipe, so that when the valve is unseated water may escape through the bottom of the overflow pipe and when the Valve is seated water will rise in the' vertical overflow pipe and may overflow into the usual waste pipe. The valve is operated by connections extending up to an operating lever mounted in a cap forming part of the closure of the upper lim end of the waste pipe. The operating lever Veating with the openin is provided withk means yieldingly retaining it in either a valve opening or valve closing position substantially as hereinafter more specifcially .and as illustrated in the accompanying drawings in which f Fig. 1 is a vertical section showin my improved fittings applied toa bath tu and Fig 2 an elevationof the operating mechamsm. l
In the#k drawings like numerals vof reference indicate corresponding parts inthe different figures. y f
lis aportion of the bath tub with the bottom outlet of which the waste pi e 2 is connected in anyknownmanner. his waste pipe. Vcommunicates with an upwardly extending .overflow ipe 3 which is surrounded by the usual over ow waste pi e 4 communit l in t le side of the bath. .The yconnection tween the pipesis through the medium of an integral connection of .T-form, which-is shaped to form a llateral connection 5 for the connection Vof the waste pi e 2; a T-h'ead 6, to the upper end of whic theoverflow pipe 3 is connected, vwhile at the lower -end is formed an o enin sha ed to kprovide a valve seat 9 for t 1e .va ve p u 7; and a sleeve 8 forming a passage aroun the T-head 6, the upper end offthe'sleeve being connected with the lower end of the wastepipe 4:,A while the lower end is ada .ted for connection to the pipe leading to t e drain.
v vThe valve plug is preferablyformed of metaltaperin Vin an upward direction so as to facilitate ow of the overflow pipe when the dischargeopening is closed. y
The valve plug 7 1s also provided at its upper end with a spider 10 a apted to guide it 1n the overflow piper3 without interfering with the flow of water. Y f
The valve plugv is operated through the mef Vdium of a flexibleconnection 11 secured to its upper end and rovided with a turn buckle 12 whereby lts length may be adjusted.
usually be provided with a closure 14 having a lateral openin 15 adapted to be fitted in the opening in t e wall of the bath tub and securedthereto by means of the threaded clamp ring 16. A cap 17 is fitted over the ring 16 and is held in position against the inner wall of the bath tub b `means of vone or more screws 18 passing t rough the cap and threaded into lugs 19 carried by the closure 14. In the cap is formed an opening 20 forming a seat for the ball 21, the ball and opening being of such a size that the inner end of the lever may be projected through the opening until the ball en ages in the lat- 1 ter as a seat. The ball is o slightly larger "diameter than the opening so that it will not pass therethrou h. The inner face of the cap 17 is provi ed with a pair of cam surfaces 22 against whichbears a plate or washer 2,3 slidable on the inner end of the lever 13.
A coil spring 24'bea`r's against this washer and against4V abutment nuts 25 threaded on lthe stem. The coil spring thus presses the washer 23 against the cam surfaces and at the `same time holds the ball 21 in seated position. The ycamv surfaces are preferably formed in two. parts at an an le to one another so that, when the lever is rocked, the washer will engage either one or the other `of these inclined surfaces and thus tend to holdthe lever in the position to which it has been moved. Two such positions are indicated in the drawings, in one of which, as shown in full lines, the valve 7 is closed, while in the other, vas shown in dotted lines, it is open.
It will be noted from Fig. 2 that the seat forl the ball 20 is partl formed in the cams. 22. The lever is provi ed between the cams with Hat sides bearing against the inner sides of the cams, thus acting as a guide for the lever l'preventingl turning or twisting of on the inner side of t e cap; and spring actuated means on the inner end of the lever engaging the cam face, the latter being iigured to tend to retain the lever, by its engagement with the sliding member, in either of at least two positions..`

Improvements in waste pipe fittings including a-down-iow waste pipe; a valve controlling discharge through the same; means for actuating the valve extending up through the waste pipe; a closure for the upper end of the waste pipe having a lateral opening; a ca for said opening detachably secured in p ace and having an opening therein; an
operating lever for the valvev actuatin means adapted to be projected through sai opening from the outside, the wall of said openving and the said lever being formed with engagmgV parts forming a bearing on which said lever may rock up and down; a 'cam face on the inner side of the cap; a washer slidable on the inner end of the lever; an abutment on the lever' and a coil spring positioned on the lever between the abutment and washer and pressing the latter against the cam face.

the latter and thus maintaining the action of the connection 11 and plu 7 directl ,up and down. I show the llat si es on the ever as formed on an extension of the ball 20, which, of course, is reall a part of the; lever.
VFrom the above description it will be seen that it `does not matter'whether the cap 17 entirely shuts off the upper overflow opening or not as the main overflow is up the pipe 8 and then down the waste pipe 4 to the soil pi Y IIE will also be seen that the movable parts y are readily removable at any time for adjustment or repair. `What I' claim as my 'invention is: Y 1.
