WASTE-VALVE.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed May 8, 1914. Serial No. 837,209.

To all whom it'may concern:

Be it known that I, WILLIAM BARTHOLO- new, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in l/Vaste-Valves, of which the following is a specification.

My invention relates to valves, and in particul'ar to waste valves for washing machines or other fluid containing vessels.

In the construction of washing machines, particularly those of the rotating cylinder type, it is found to be desirable to locate the waste outlet on the lower side of the tank intermediate the ends thereof, in order to insure a readv and complete draining of the contents and it has been the usual practice to provide a waste duct or pipe leading from this outlet to a point adjacent the end or lateral wall of the tank where a valve may be conveniently located therein to control the discharge of the waste water. The portion of the waste pipe between the outlet from the tank and the valve forms a pocket in which the dirt and sediment from the interior of the tank collects to be later intermingled with the contents of the tank after a new charge of fresh water has been introduced therein.

T 0 overcome this objectionable feature, I

have provided an improved form of valve.

which is adapted to be located in close proximity to the outlet aperture in the bottom of the tank so that the waste water and suds or the like may be discharged directly downward from the tank into a suitable gutter or drain. By this construction a method is provided for thoroughly cleaning the tank of its waste contents so that no dirt or waste suds will remain to intermingle with the next charge of clothes and clean water. I further arrange my valve in combination with steam and fresh water inlet'pipes, so that fresh water of any desired temperature may be introduced into the tank of the washing machine through the same aperture which serves as a discharge outlet.

A further object of my invention is to provide a valve for thepurpose stated, which requires no stufling-boxes to insure the chicient operation thereof.

" A further object is to provide improved means-for adjusting the valve relative to its i Still another ob ect is to provide a valve of the kind referred to, which may be operated from a convenient position adjacent the washing machine.

Other objects will be set forth and made apparent in the following specification and accompanying drawings, in which I have chosen to illustrate and describe my invention as applied to a washing machine ofthe horizontal cylinder type.

In the drawing Figure 1 is a side elevation of the lower part of the tank of a cylinder type washing machine showing my invention applied thereto;

Fig. 2 is a side elevation of the header and inlet pipes showing a vertical longitudinal section of my improved valve in closed position;

Fig. 3 shows a vertical longitudinal section of my valve when in opened position;

Fig. t shows a transverse vertical section I ofdthe valve casing and associated parts; an

Fig. 5 shows a bottom plan view of the carriage member.

Like numerals are used to designate like parts and elements in the several figures of the drawings, in which 10 designates the tank of a cylinder type washing machine supported on the usual legs. 11, and provided on its under side intermediate its ends; with an outlet aperture which is engaged by the upwardly extending annular flange 12 of a header 13, having the fresh water inlet pipe 14 and the steam pipe 15 leading thereto. The header 13 is provided with a laterally extending flange 16: which is adapted to be secured to the lower wall of the-tank by suitable means to form a water'- tight connection therewith. The lower flange 17 is secured to and forms a similar tight connection with the outwardly extending flange 18 of a valve casing 19'.

The valve casing 19' is: provided with a duct 20 which is directly below the aperture in the tank and communicates therewith through the header 13. An annular valve seat 21 is formed at the lower end of'the duct 20 and a valve cap 22 is arrangedto, coact therewith when in closed position to close the said duct. The valve cap 22 is" preferably hollowed out within the walls of the duct 20-, as shown at 22, in order to de- I ll ill

The cap is carried by a carriage member 23 which is adapted to slide on opposite guide flanges 2-1, formed on he inner walls of the casing 19, and thereby move the cap 22 substantially parallel to the plane of the valve seat 21. the carriage member is provided at one side with 11pm "dly turned lugs 25 l etween which is pivoted a connecting member 26 having the internally threaded socket 2.7 adapted to engage an operatcably mounted ing rod 28 which is recipro in the end wall of the laterally extending portion 19 of the casing 19. The casing 19 is preferably so mounted on the header 13, that the rod 28 may be extended longitudinally of the tanl; beyond the end wall thereof where suitable means may be arrangertor reciprocating the rod in order to slide the carriage member 23 on the guides 24 and thereby open or close the duct 20.

it will be observed that the guides 24- en tend laterally into the portion 1ST of the casing and are provided with stops 2% at their extreiiities so that the lateral movement or the carriage memher will be limited at the point where the forward edge of the cap 22 is still engaging the valve seat, as shown in Fig. 3, where the valve is shown in open position. To prevent lateral swaying of the ca 'iage member transversely to direction of movement, said member is provided with shoulders 23 which coact with the inner faces of the guide 2%, as shown in 4. The u per faces o'f the guide members 2% erably inclined sligh ly toward t in order that the valve will open readily and to fun ther insure a tight seatingof tlie valve cap when in closed position. The valve cap 22 is provided with a pair or symmetrically arranged depending lugs 29 which reciprocably engage the corresponding; apertures 30 in the carriage member 23 whereby movemen or the carriage member 19 on its guides will cause a correspondine translation of he cap relative to its seat. A washer 31 is inserted between the carriage member and the cap member and is provided with apertures EtdZlPtGO. to

t rtures 3O anl directly beneath -h en'er of ti o cap 22, the carriage mem 's p ovided with a threaded aperture. engi ged by a stud 33 having; a slot 33 in its end which may be engaged by a screw-driver or the like. A lock-nut e lower end of the stud 83 within the depression 3 5 on the engage the lugs 29. Be-

lower face oi tl-e carriage i. ei ber and thereby maintain tl-e ail stud i.- any de s sired position relative to th e carriag H1611:

here By means of LlllS stud he (.istance 1 member may ressure of said be apparent that I have provided improved means for discharging the waste water from the interior of a washing machine or other vessel and that l have also provided means whereby fresh water may be introduced through the same aperture that serves as a discharge outlet in the tank wall.

"il hen it is des red to remove the waste contents of the machine, the rod 28 is moved to the left, as viewed in Fig. 2, thereby opening the duct 20, as shown in ig'. 3, so that the contents of the cylinder may discharge directly downward without having to pass through any intermediate passage which may serve as a pocket for the waste products. t will be apparent that during this discharge, none of the water comes in contact with the bearing 28 of the rod or stem 28, so that it is entirely unnecessary to use a striding-box of any description in order to insure a tight closure of the outlet duct. it is further apparent that after the parts become worn, the loch-nut may be loosened and the stud 33 moved upwardly to force the cal 22 into tight engagement with the valve seat, after which the lock-nut S t may be again tightened to preserve the parts in their new adjusted position. After a charge of waste water has been discharged from tie tank, the valve is again closed and steam and water may be introduced through the pipes 1e and 15 into the header 13, where they intermingle and then pass into the tank 10.. By this arraneement it is apparent that the steam will combine with the fresh water within the header 13, so that there is no danger of causing injury to the clothes within the tank by introducing hot steam directly therein.

l have shown and described my improved valve in connection with the header l3 and water and steam pipe 15, but it will be understood that the last named parts may be dispensed with in this connection, it desired, and the valve casing 19 secured directly to the wall of the tank.

While I have described in detail a particular form of my invention, as applied to a particular form of washing machine, i
