To @ZZ whom t may concern.'

Be it known that PHILIP MUELLER and ANTON C. SCHUERMANN, citizens of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Waste .Stoppers and Operating Mechanism, of which/the following is a specification.,

This invention relates Ato waste Stoppers for bowls, lavatories, and analogous devices, and to an improved constructionin the operating :mechanism thereof. The present case is a division of application, Serial No. 337,496, filed Nov. 12, 1919, Patent No. 1,447,808, March 6, 1923. y

Itis customary in wastefstopper constructions*A of this" type to'have parts of the operating 'mechanism disposed within the stopper, which necessarily has a tendency to obstruct the. passage of wat-er and foreign material passing'through the stopper` and eventually cause the clogging or stopping up of the waste outlet. p y

In order to overcome these defects, the present development provides means arranged outside of the stopper, for actuating the same, so as to permit a free and unobstructed passageway through the waste outlet.

The present invention has further for its object an adjustable waste iitting that is adapted for use with 'bowls of diiferent thickness, and bowls in which the waste outlet is positioned at different heights relative to the faucet or supply spout.

lA still further advantage of the'present construction resides in providing an actuating mechanism in ,which the lifting rod is adapted to give a straight lift to the stopper without imparting any turning movement to any'of the parts, thus dispensing with the complicated connections employed in, similar devices, wherein a 'rotary movementy is impartedto'the stopper forlefl'fecting operation ofthe same.

' fIn the drawingsherewith illustrating embodiments of our invention, j

F'fgure 1 fs aview in centraljV vertical section of a bowl equipped with a waste xture made in"l accordance with 'our invention.'

Figure 2 is ahorizontall sectional view VVon substantially/'the line 242ofr1igure 1,'show- ,ing thaw-aste Stopper-Tantas! actuatinjgriyoke.

Figure 3 is a detail view in vertical section on the line 3-3 of Figure 2.

Referring to the drawings, wherein like numerals denote like parts in the various views, 10 designates a wash bowl of any suitable material, design, and dimensions, and preferably composed of vitreous ware, although it is obvious that our invention is adapted to bowls ofy varied material and construction..f Y

Thejbowl 10 is formed with the usual bowl slab 11, aback slab .12, and may be pro; vided with an overflow'13 vleading to the waste outlet arranged in the' bottom of said bowl. p 1

The'said waste outlet isprovided with a sleeve fitting. 14, passing through and below the bottom ofthe bowl, and formed `at its upper end with anoutwardly extending shoulder 15, vwhich is adapted to abut the gasket 19 preferably arranged in theV recess in the bottom of the bowl 10. The sleeve 14 extends an appreciable distance below the bowl r'and is externally threaded throughout the greater part of its length so Ythat the'adjustable housing 16 and thepacking 17 may be effectively' secured to the bowl.

A hollow tubular stopper 18 is provided at-itsupper vendwith a conical head 18i adapted/to. abut aga-inst and be supported by a conical seat in the end 'of thev sleeve 14. The stopper is further provided at its upper end with a plurality of slots 20 for permitstopper 18 is provided with diametrically opposed grooves 23, and flat sides 24, as shown in Figures 2 and 3, for a. purpose now Vto be set forth.v

' An actuating yoke 25'is adjustably mounted on a lifting rod26 passing through the housing- 163 {The arms 27 of saidyoke are normally arranged? to straddle the lower end ofthe waste stopperand iit within `the.

grooves 23, thus preventing the disengagearms 27 untilthe iiattene'd portions 24 are arranged infparallel alignment therewith, "Wherfllsetharsis stepper Ami' be readily Vment or'V removal 0f thestopper-from the withdrawn. The lifting rod 26 passes through a stui'iing boX 27 formed in an ordsct portion otl the casing 16, and its movement is steadied by means of a guiding lug 28 formed in the interior of the housing and through which the lower end of the said rod is adapted to pass.

A substantially L-shaped member 29 is adjustably connected to the rod 26 by the pin 30, which is threadedly connected to the member 29. An operating rod 31 is similarly secured to the vertical portion of the member 29, and passes through and beyond the supply spoilt 32 so as to provide at its upper end an operating knob or `handle '33 for actuating the waste stopper 18. .A tube 34 surrounds' the operating rod within the supply spout and is threaded or otherwise secured at its upper extremity within the neck of the spout 32, and at its lower end to the securing nut 35.

With this arrangement it will be seen that a suitable range of adjustment is provided to meet diiierent conditions arising through the variations of the thickness ofV the bowls 10, or the positioning of the supply spout 32 at different angles with respect to the waste stopper 18. Furthermore, by arranging the arms 27 ot the fork 25 to exteriorly embrace the stopper 18, an unobstructed passage is provided within the stopper so that water and foreign material may easily and VJfreely pass therethrough without danger of obstructing sediment and clogging up the outf let.

j while a preferred embodiment of the same is merely lillustrative and in no sense restrictive, for the construction may be varied as to mechanical details without departing from the spirit of the invention and the scoA e of what is claimed.

i' VVTe claim: Y

1. The combination in a fitti-ng of the class described, of a stopper, astopper casing into which the lower end of said stopper projects, a vertically disposed liftingrod extending from said casing, a vertical-ly adjustable yoke on said rod and embracing said stoper. and Vmeans on said sto s er for lookin@r i b the Yparts together when the stopper is rotated in a predetermined position.

2, The combination a -iitting er the class described,o: t a stopper, a stopper/easing into which the lower end of said stopper projects, a vertically disposed lifting rod extending trom said casing, a vertically adjustable yoke on said rod and embracing said stopper, means on said stopper for locking the parts together when the stopper is rotated in a predeterinined position, and means in said casing for guiding the lower end oi said lift-ing rod.

3. rl`he combination in a fitting ot the class described, of a stopper having a groovedl lower end and flattened opposite sides, a stopper casing into which the lower end of said stopper projects, a lifter rod in said casing projecting eXteriorly thereof, a yoke adjustably mounted on said litter rod and engaging said grooved stopper, and means to prevent accidental rotation of said stopper and disengagement of said yoke, said means being removable to permit the stopper to be rotated in the yoke and withdrawn when the flattened sides are brought to a predetermined position.
