WATER-MIXING: VALVE.
Application filed April 6, 1925. Serial No. 21,066.
To all to 710m it may C07'LC6TIL Be it known that I, Onvrs W. VALLIER, a citizen of the United States, residing at VVatertown, in the county oi J eiferson and State of New York, have invented certain new and useful Improvements in ater- Mixing Valves, of which the following is a specification.
This invention relates to improvements in mixing-valves designed for supplying water to tub and shower baths, lavatories, sinks, and the like, by means of which colol and hot water may be dispensed by a single valve and a single control.
The object of the invention is to provide a casing whose interior is formed with a valve-chamber, in which is rotatably disposed a valve, the said valve being formed with a concentric mixing-chamber which communicates with the valve-chamber, by means of radial ports; the said casing being formed at opposite sides with hollow arms that respectively supply coldand hot water; the ports of the valve being disposed in the same plane as the axis of said arms, and
adapted when the valve is rotated, to conduct the water into the mixing-chanibe1z .A further objcctis to provide-a stem which is fitted with a handle for operating the valve. A further object isto provide means for reciprocating the stem axially relatively to said chambers for dispensing-the cold and hot water. A further object is to provide an adjusting member that is arranged con centric to the stem and cooperates with said reciprocating means for holding the valve in its seat. A further object is to provide means for stopping the rotary movements of the stem and valve immediately the valve is closed. A particular object of the present invention is to provide novel and simple means for preventing leakage of water through the top of the valve casing, comprising a non-rotatable washer-like part, which is mounted upon the adjusting member concentric to said member and said stem, at relatively thick circular packing member which overlies said washer, and is held in place by a cap, which closes the top of the casing and compresses the packing in a manner to prevent leakage around the adjusting member and stem.
This invention relates particularly to improvements in the mixing valves shown and described in my pending applications Serial,
Nos. 2,346and 15,955, filed respectively January 1 1, 1925, and March 16, 1925.
I attain these objects by the means set,
forth in the detailed description whichfollows, and as illustrated by the accompanying drawings, in which- Figure 1 is a central vertical section, taken on line 11 of Fig. 2. Fig. 2 is-a horizontal section taken on line 22 of Fig. 1, showing the valve positioned for dispensing cold water. Fig. 3 is a horizontal section taken on line 33 of Fig. 1. similar section, taken on line 44 of Fig. 1. Fig. 5 is a similar section,-takenon line 5-5 of Fig. 1. Fig. 6 is a broken horizontal section taken on line 2-2 of Fig. 1, showing the valve set for mixing cold and hot water. Fig. 7 is a similar view, showing by full lines, the valve positioned for drawing only hot water; the dotted lines of this view showing the valve closed. Fig. 8 is a hori- Fig. 4 is av zontal section taken on line 88 of Fig. 9,
water. And Fig. 9 is a central vertical sec-- tion taken on line 99 of Fig. 8.
In the drawing, the mixing valve comprises a casing or body 2, which is formed with a-hollow cylindrical portion 2, a 1101- low neck 2 that aligns axially with said portion 2, and with atapered valve seat 2, between said port-ions. At opposite sides of the casing are disposed arms?) and 4, which are arranged at right angles to the axis of the valve chamber and respectively conduct cold and .hot water to the chamber 2 by means of aligning ducts 34. The arms 3 and 4 are shown threaded intothe casing, but these parts may be integral with the casing.
The dispensing ofcold and hot water 111- dependently, as well as the mixing of said water, is efiected by means of a valve 6..
Figs. 1, 2,6, 7, S and 9. Above the mixing chamber the bore of the valve 6 :is reduced,
and above said portion the body is formed with an enlarged socket or cavity 6 The top end of the valve body is formed with diametric slots 6 The valve 6 is preferably nonmetallic for reducing friction and wearing of the parts. The valve is rotatable by means of a stem 7, which is loosely disposed in the axial bore of the valve body, and has a reduced lower end portion 7 that extends into the chamber 6'. This end of the stem is formed with a threaded hole to receive a screw 8, which supports a disc 8, the said disc being larger in diameter than the stem and preventing the stem from being accidentally withdrawn from the body. The reduced portion 7 of the stem is longer than the adjacent contracted bore of the valve body and allows the stem a slight movement axially relatively to the body, as may be understood by comparing Figs. 1 and 9. The medial portion of the stem is enlarged, as at 7 and this portion is normally disposed in the cavity 6", the said portion being perforated diametrically to receive a pin 9, which is loosely positioned in the slots 6'", and is employed for driving the valve, as well as for preventing rotation of the stem in the valve. Above the socket ti the stem is formed with coarse box-threads 7", and
above the said threads the stem is reduced again, as at 7, and its top end is fitted with a handle 10, by which the stem and valve may be rotated as one part. The threaded portion 7 of the stem is engaged by a cylindrical nut 12, the latter having a flange 12, and said flange being formed with oppositely facing peripheral lugs or ears 12, which are disposed in similar longitudinal guide-ways or grooves 2 of th casing, for'rendering the nut non-rotatable. The valve 6 is held operatively in its seat by the nut 12, an adjusting member 13. which is threaded into the top end of the casing 2, and a sleeve 1% which is disposed between the nut and the body of the valve (see Fig. 1) By the fore-. going construction and arrangement of the parts, the stem when rotated by'the handle is reciprocated by means of its threads engaging the nut 12, to theextent allowed by the vertical play of the pin. 9 in the groove 6. For example, when the handle 10 is swung in one direction, the stem is carried upwardly by the nut 12, and the pin 10 engages'the bottom end of the sleeve 14. This stops the further rotation ofthe stem, lVhen the handle is swung'in the opposite direction, th enlargement 7 bottoms in the cavity 6' which again stops the rotary movement of the valve and stem. The spacing of the disc 8 and the said enlargement determines the greatest distance the stem may be moved axially. The member 13 is provided with sockets 13, for the use of a. spanner wrench, by which its adjustments may be effected. When the mixing valve is,

dispensing of warm water.
assembled, the member 13 is screwed downwardly until it bears against and forces the nut 12 and the sleeve 14 in the direction for operatively seating the valve 6. The member 13 is then left in that position until the valve or its seat becomes worn to an extent that requires readjustment. Upon the top face of the member 13 is disposed a washerlike guard 15, whose normal diameter cor The washer 15 is provided with similar peripheral ears 15 that engage the grooves 2 of the casing, like the flange of the nut, for preventing rotation of the washer. Upon the washer 15 is then disposed a relatively thick layer or sheet of packing, as 16, the said packing preferably being large enough in diameter to overlap the top-end of the casing 2, as shown in Fig. 1, thereby tending to prevent water. that might well-up in the casing, from leaking through the threaded joint of the parts 2 and 13. The packing 16 is compressed against the washer and the casing, by means of a screw-cap 17, which engages external threads of the casing. For this purpose, the inner face of the cap is arched, as at 17, and when the cap is screwed down tightly upon the packing, the latter becomes compressed downwardly as well as radially against the stem and the casing for preventing leakage, between or around the said parts. The particular use of the guard 15 is to prevent the packing, which is more or less adhesive, from accidentally disturbing the adjustment of the member 13, in case th packing tends to retate with the cap 16 ..when the latter is screwed in either direction. This is an important feature of the invention since it effectually obviates all danger of the valve being loosened relatively to its seat and causing leakage, when the valve, while idle, is subjected to the usual service pressure,
which ordinarily ranges from sixty t-o eighty 1 pounds.
According to the showing in Figs. 1 and 2, when the handle 10 is in the full line position (which corresponds to the full line radial arrow in Fig. 2'), the port 6 of the valve is positioned to draw cold water from the arm 3 into the chamber 6, from which the water may gravitate towards the neck 2, and thence through a discharge member 18. VJhen the handle is swung to the central dotted position (see Fig. 1, and the radial arrow in Fig. 6), the ports 6 and 6 are in comn'iunication respectively with the cold and hot water ducts 3-l, which effects the And when the handle 10 is swung to the right dotted position of Fig. 1 see also full line radial arrow in Fig. 7) the valve is positioned for drawing only hot water from the arm 4. The
reversing of the handle 10, likewise reverses hot water.
, The closing of the valve 6 is effected by swinging the handle 10 to correspond to either of the positions shown by the] dotted arrows in Figs. 2 and 7 In Figs. Sand 9 is shown a four-way mixingvalve whose casing 2 is formed with a cold waterreceiving' arm 8*, which connects with the valve chamber 2 by a passage 3*,
and a hot water arm 43 that connects With the-chamber 2* by a similarpassage 4P. In
this modified casing, thevalve 6' and related and controlling parts are intended to'be the same inall respects, asshown in Figs. 1 and 2, and" said valve is shown in a position corresponding to the showing in Fig.6, for dispensing warm water. water gravitates from the mixing chamber 6 into a relatively large compartment 2, which is in normal unrestricted communication with similar diametrically arranged'discharged openings 2 2 that" are adapted to carry the water dispensed by the valve, as for example, to a bath tub, as well as to a showcr'head (not shown), as shown by the drawings of my pending applications.
My improved mixing valve is extremely sim ale, and aif'ords novel, convenient and effective' means for controlling the supply or" water at different temperatures, by means of a single control; The means for preventing accidental disturbance of the valve after it has been properly adjusted relatively to its seat, as by the rotation of the screw-cap 17, and the disposition and arrangement of the washer 1'5 which prevents ready access to, or tampering with the adjusting member 13, enables me to produce a fluid dispensing valve with fewer parts, which is more compact and durable, and is less liable to leak orot-herw ise become disordered, than any of the older fittings of the class, known to me. The packing 16 is the only means require for preventing leakage of the mixing valve, and when said packing is applied, as herein shown and described, and the cap 17 and other related parts are properly adjusted, the valve will Withstand constant use for long periods of time, without attention or care of any kind.
