MIXING VALVE.
Specification of Letters Patent. Patented Aug, 29, 1922 Application filed September 29, 1919, Serial No. 327,187. Renewed March 6, 1922. Serial no. 54,1,587.
Toall whom- 't vii/i7; concern:
Be it known that PATRICK T. Lear-n, citizen of the United States.,residing at Cleveland, in the county of Cuyahoga and State of Ohio, has invented certain new and useful Improvements in Mixing Valves, of which the following is a specification.
This invention pertains to an. improvewith the valve disk turned to a mixing position. Fig. 6 is a perspective view of the valve stem and Fig. 7 a perspective view of the valve disk.
Theinvention comprises a cylindrical open body 2 having a closed bottom '3 with a flat upper surface adapted ,to provide a rela tively large sealing seat for a round fiat valve disk 4;. Body 2 also has a rib or projection extending diametrically across its bottom in which two separate water intake passages 5 and 6are provided and with which two separate supply pipes are adapt ed to be connected by screw-engagement at opposite sides of the body. Each passage has a. vertical discharge orifice or port at its inner end extending through the bot tom 3 opposite valve disk 4:, and said valve disk is also provided with a pair of openings adapted to register with said orifices, or ports. These orifices, designated 7 and 8, and separate openings 9 and 10 in the valve disks, are set the same distance from the center or axis of the valve disk, but the openings in the disk and the orifices in the body are off-set relatively to each other in respect to a given center line so as permit control of the water passing through either orifice singly or both orifices jointly. Thus, the orifices 7 and 8 in the bottom of the body are both located a short distance to one side of a diametrical line extending through the body, while the openings 9 and '10 in the valve disk are located directly on a diametrical line extending through said disk.
When the parts are assembled with the valve disk in a cut-off position the openings 9 and 10 in the disk are distantly removed from the orifices 7 and 8 in the bottom3 and are-located on a diametricalline which is at right angles. to the axis or adia-metri cal line of the water intake passages 5 and 6. One of the openings in the disk, in'this instance opening 10, is less than 90 degrees distant from either orifice 6 or 7 whereas the other opening 9 is at a greater distance than 90 degrees from both said orifices, measured by a rotary movement of the valve disk. The result is that less than a quarter turn of the valve disk is required in either direction to open either the hot water or the cold water orifices, while slightly increased rotation of the valve disk from an open position of either the hot or cold water orifice will then bring both openings 9'and 10 in register and open communication with both orifices 7 and thereby permitting theentrance of both hot and cold water into the mixing chamber 11 of the body. 'Equal amounts of hot and cold water can be taken in by rotating the valve disk so 'that the openings and orifices provide entrances of equal size, or a diiierent mixture can be obtained by rotating the valve disk either to the right or the left to reduce the size of one of the entrances and enlarge the size of the other entrance simultaneously.
The valve disk is held centrally within the recessed bottom 3 by an annular shoulder 12 which is adapted to engage the periphery of the disk, and the central part of the disk is slightly reduced and projected upwardly and provided with a pair of'fiat sided lugs 14 and 15 arranged on opposite sides of a central round recess or cavity 16 in the up per face of the disk. A round valve stem 17 has a short round projection 18, at its inner end which extends and seats Within recess 16, and this stem is interlocked in separable union with the valve disk by an annular flange 19 having notches on opposite sides of the stem to accommodate and receive the lugs 14 and 15. A slight play is afforded between the stem and valve disk to permit the valve disk to always remain in flat seating relations with the bottom, and the disk is ground to its seat in bottom 3 before the parts are assembled to effect an absolutely Water-tight joint. Permanentand effective seating engagement between the valve parts is obtained by a coiled compression spring 20 Which rests upon theflange 19 of the valve stem and bears at its upward end against a shoulder 21 in the scnew cap or cover which is screw-engaged with the upper open end of the body. The extremity of the valve stem projects through an extension 23 on said cap and through a screw ring or iglan'd member 24' which is adapted to compress and confine suitable packing material 25 about thelstem. A hand le 26'is detachably fastened to the upper end ofthe stem and this handle may be provided withaa projecting finger 27 adapted to beshiftedopposite different index or des ignating characters on the 'extendedllange or dial ring 28 of the cover or cap so that the operator may be guided in turning the valve disk :to =an-0pen or closedposition, either for delivering hot 'or cold separately or a :mixed' discharge ofvvater through the single outlet 29 at one side of body 2.
The device comprises practically only seven pieces or parts,to-wit: body 2, valve disk 4, stemClT, spring 20,cap 22, gland memberQQ-and handle 26. Body 2 is plain and a simple and inexpensive member to cast and produce; the relatively'largewflat seat is accessible through the relatively large and'Wide-open chamber and endof the body; the-valve disk and itsseparatestem are easilyfitted to each other'and to the body and also adapted to accommodate a slight-irregularity of movement between the parts; and the coilspring bars centrally down upon the valve stem and holdsthevalve disk firmly to its seat in all of its rotative movements.
What I claim is:
1. A mixing valve comprising an open body having a side outlet and a flat inner bottom surface provided with a pair of separate intake ports, a valve disk having openings adapted to register with said ports and provided with a lug at one side on its top, a valve stem in separable engagement with said disk having a notched flange adapted to receive and engage said lug, a cap detachably engaged withsaid body adapted to support said stem, a compression spring sleeved upon said stem between said cap and the fiangeon thestem; and an operating handle for said stem.
2. A mixing valve-comprising a body having a mixing chamber with adischargeoutlet and provided with an inner flat recessed surface having a pair of intake ports located in onedlateral half thereof, a flat valve disk having a pair of-openi-ngs located on oppositesides of its center on the diameter of said disk and providedat its upper side with a'central recess and lugs at opposite sides of said recess, a valve stem having a rounded projection at its lower end adapted to-seat in said recess andprovide'd with a notched annular flange fixed thereon and engaging said .lugs -a screw cap for said body-having an -openi-ng centrallyiifor said valve stem, a compression spring sleeved upon said stem between said cap and "valve disk, and an operating handle detachably affixed to said .stem outside-:of said cap.
Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this '26 day of July, 1919.
