Application led October 23, `1922. Serial No. 596,362.
My invention relates to improvement in waste valves. The object is to provide a simple and efhcient valve and cooperating valve seat and also an improved valve'actuating mechanism having "simple, efficient and convenient mea-ns for adjustment, and adjustable friction means for maintaining; the valve in anyv position to which it has been moved by arbitrary actuation.
`Referring to the drawings, which illustrate merelyby wayl of example suitable means for the embodiment of my invention :e
Fig. l is a longitudinal vertical section showing some parts in elevation, showing the valve in open position.
l Fig. 2 is a' similar view showing the valve closed. o
Fig. 3 is a horizontal section on the laines 3 3 of Fig. 2.Y
VSimilar numerals refer to similar parts throughout the several views.
The tubularformation 5 is provided' with the flange 6V at its upper end, having the ya ye seat formation 7 onits upperv surface, andy engaging on its underside with the beyelled wallS 4at, the bottom of basin or bowl 9. The tubularV formation 5 has the opening l() communicating with the channel ll, from the overflow l2 of. the basin. The lower extension of formation 5 is provided with the exterior thread74 as at 12, for cooperating with nut 13. This nut 13 cooperates with washer 14; andY gasket l5 for securing r water-tight oint between flange 6, and wall 8l and between gasketl5 and the underside le of the basin wall. rlihe threadedportion l2 is of ample extent to `permit the Vtubular formation.. t0 be fitted, t0. basins 0f Widely Varying dimansions.`
The 'lower' threaded end of the tubular formation isin threaded engagement with the bowing membeler body'l, made Wetertight by the washer 18. The lower end 19" of body l? is provided with anV interior thread? for engagement with the waste pipe 20. The. body lrSis also provided, on 'one Sida theme13 rita the. Grdrial 'formation l for the lpurposetoghe'explained later.

, tionl ofj y seat" the topfolf i the'tubular fermation 5f." s eatl surface"V is in"tl1e of' a: bevel, hanna the hlghestlme et..
the underside of member 2 3, is provided the 60 washer 25` having its, peripheral margin 26 preferably short olf the inner margin of flange 24. This washer 25Y is held in place between member or plate 23 and the ripper flanged head 27 of the valvespindle forrnfa-r G5 tion 28, by means ofV the screw 29.; The
valve spindle formation 28, is also pro;yidedV with the wings 3,0 for maintainingiproper axial position within vthe tubular body 5. Spindle formation 228 is also provided atj'its lower` extremity, with the head 31.
The cylinder formation 2 1 is shown as ifn tegral with the chambered body 17 and is in open communication with 'the interiorv of chambered body 1'7. lts axis is horizontal, and it forms a housing for the solid cylindrical formation 32y which h as a close. butmov` able lit therein.v Into, the'. side of' this formation 32 is secured, as'by athread,jthe arm or rod 33, the free Vend of which projects into the chambered body 17 andbeneaththe head 3l of spindle. 2,8.J Shaft 34 projects? from one end ofthe member 32 andis preferably integral therewith. rlhe cylinder2l is closed at one end and is open at the other end and provided with an interior thread,v as at 35, for receiving thel threaded plug 36 preferably provided with the knurled head 37 for convenient manipulation. This head 36 is centrally apertured'for receivingy the shaft34 which yprojects therethrough. At the closed end of cylinder 21 is providedA the spring washer 38r between the; end`V of member 32 and the closedl cylinder en d wall. Between thefplug 36 and 'the other end of member 32areprovided one orv more washers 39 of yieldingmaterial such as felt.
l The outer extension of shaft 3.4 is preferablyYia-ttened, as at 4a), formo-reetfeetive engagementfwith set screw 4l. A111; or crank` member. 42.v ifs rigidly securedV Vto, thef end offV shaft 3a by means of; the; serJ screwA lll. Thisarm @has aneXtension, 4 3fparallell with the' axis Aof-v movement` of- 'member 32 and is loosely secured to.k the horizontal rodete, which isadjustablyv conneotlm @h3 -ing packing.
vertically movable actuating rod 45, which has an operating knob 46 at the top and a suitable housing, as at 47, with adjustable means for connecting same to the basin slab, as at 48.
The connecting means between the vertical rod 45 and the horizontal rod 44 comprises the connecting body or member 49 having transverse channels, one for receiving the vertical rod 45 and the other receiving the horizontal rod 44. Vertical adjustment is securedby means of the series of holes 50 in rod 45, adapted to receive cotters 5l above and below member 49 as shown. The horizontal adjustment of rod 44 in member 49, is secured by set-screw 52.
The voperationis as follows:
As above stated, the long threaded portion l2 permits the tubular formation 5 to be fitted to basin orsimilar structures having walls differing substantially in thickness.
ing from member 32, beneath the head 3lof spindle 28, serves to raise or lower the spindle 28 and consequently open and close valve 23.
A special feature of the member 32 and its operation, is that said member 82 is inter'- posed between the spring washer 38 and the washers 39 of felt, or other suitable yield- The threadedV plug 36 is screwed into the end of the cylinder housing 2l, against washers 39 and exerts pressure thereon, which pressure is communicated to the member 32 and the spring washer 38. This pressure may be varied as required, by the simple manipula-tion of the plug 36; and consequently the friction between the member 32 and the washers at each end thereof, may be brought to any desired degree of efliciency. The result is that when this `tension and the resulting friction is properly adjusted, the member 32 may readily be rocked in either direction by simply raising or lowering the knob 46, andthus the valve will be opened or closed as desired, and, in addition to this, the friction exerted on member 32, will maintain the parts securely at any positionat which the arbitrary actuation ceases, so that the valveY maybe opened or closed or'partly opened for partly closed, and inwhatever position left,`-in said" arbitrary actuation, .the valve will remain, until aga-1n positively actuated.
This is considered a distinct advantage in tllie actuating mechanism of valves of this c ass. Y
Another feature of the construction herein described, is the valve seat formation and construction. The yupper surface of the flanged tubular formation, whichforms the seat proper, is bevelled; that is, it is inclined downwardly from the inner margin thereof tothe outer margin, so that this annular bevelled seat has its highest line at its juncture with the` inner vertical wall 22 of the vertical tubular formation 5. The said outer margin has a diameter at least equal to the diameter of the outer margin of the valve, The washerv 25 of the valve element, which lis flat and formed of rubber or other yielding material, cooperates with this bevelled seat with a preliminary line engagement and causes an 'efficient closure, since the slightly raised ridge at the inner margin ofthe valve seat, tends to sink very slightly into the yieldingbody of the washer, but as it sinks, the area of engagement Vbetween thevalve and its seatis very greatly increased, and thus a. liquid-tight closure is effected with a minimum of pressure.
The parts are simple in construction, easy to assemble and have little wear or other tendency to get out of order.
