3Claims; (omit- 12) This invention relates to new and useful im- '7 provements in temperature controls and more 1 particularly to a device adapted to regulate the temperature of water leaving a spigot. The primary feature of this invention is to provide a device of the character referred to adapted for attachment to hot and cold water supply pipes, thereby regulating the temperature of'the water leaving a single outlet provided in the device.
Another important feature of the inventioni's to provide a device of the character referred to including a regulating pointer, said pointer cooperating with a slidable valve for regulatingthe volume of hot and cold water passingthrough the device.
A further feature of the inventionis to provide a device for controlling the temperature of water that is easily and quickly attached to' cold and hot water supply pipes.
tion is to provide 'adevice of this character that is strong and durable in construction, neat and attractive in appearance, efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposesjfor which the same is intended.
I Other objects and advantages reside in the-details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like reference numerals refer .to like parts throughout, andin which I Figure 1 is a front elevational view of the'teinperature controlling device for liquids. 'J Figure 2 is a rear elevational view thereof.
Figure 3 is a transverse sectional view taken on a line 3-3 of Figure 1.
y- Figure 4 is a front elevational view with cover plate removed.
;,1iigure 5 is a perspective view of the valve.
Figure 6 is a perspective view of connecting arm between the valve and pointer arm.
Referring now to the drawings in detail wherein, for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numeral 5 represents generally a housing formed of a forward cover plate 6 and rear plate 1, said plates being held together by a plurality of screws 8 which extend through the forward plate and into the rear plate.
A pair of inlet ports 9 and I0 are provided at the rear of plate 1, said ports being integrally cast with said rear plate 1.
the
slidable A still further important feature of this-[invenof water through said boss and nut.
therein slidably receiving a cylindrical valve I3 movable transversely at th inner ends of the ports9 and ID. A square shaped chamber I4 is formed in the plate 1 between the inner ends of the portsand the valve.
The plate 1 is increased in thickness in the region of'the ports 9 and Ill to accommodate the valve l3 and. the upper and lower edges of the thickened portion are leveled as shown at I5 and 15a to increase the area of the mixin chamber l6 formed between the plates 6 and I.
Projecting outwardly from the center of valv -l3' is a cylindrical lug l'ladapted for engagement 'by a slot It in the lower end of an upwardly extendingarm i9. The upper end of arm I9 is formed with a .collar20 securely held on a shaft 2 lby a setscrewZOa.
The inner end of shaft 2| is journaled for rotation in a circular bearing recess 22a. provided in a boss 22 extending inwardly from the inner face of .plate I. 1
At the upper central portion of plate 6 and extending outwardly-therefrom is an externally threaded boss 23 through which extends the forward portion of shaft 2 i A preferably hexagonal packing nut 24 is fitted ove'r boss 23 and packing 24a is placed in nut 24 and around boss 23 thereby preventing seepage -The inner socket end 25 of a circular finger "gripping'knob 26'is'held on the outer end of shaft 2| by a-set-screw 26a. r 1
Suitably secured to the inner face of the socket 25 is the upper end of a downwardly and inwardly curved pointer arm 21.
The lower pointed end 28 of said pointer arm is adapted to register opposite the center of the temperature graduated scale 29 formed on the outer face of the plate 6.
When the pointer is in this position, as shown clearly in Figure 1, the arm is is in a vertical position and valve plate I1 is centered, thereby partially closing chambers M for the inlet ports 9 and ID a substantially equal amount.
For a desired change in temperature of the water mixed in chamber 16, knob 26 is turned slightly until the pointed end 28 of pointer arm 21 opposes the desired graduation in the tempera 3 ture graduated scale 29, and the lower end of ar 19 is swung toward one side, thereby sliding valve 13 to close one of the chambers I4 more than the other and thus adjust the proportion of hot and cold water entering chamber l6.
By moving the straight ends of the valve 13 across the square chambers I4, equal movements A second outlet port 3| is provided in' rear plate 1 for receiving an outlet pipe leading to a shower, or other means. This outlet port 3|, when not in use, is conventionally plugged and, when in use, the port 30 is plugged, thereby causing more pressure to be maintained in the housing 5.
- In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claims.
What I claim is:
1. In a device of the class described, a housin including rear and forward cover plates, said rear cover plate having a pair of inlet ports, one of said inlet ports for hot liquid, the other port for cold liquid, a shaft journaled for rotation in the upper portion of the housing, the outer end of said shaft extending outwardly from the forward cover plate ofthe housing, a finger gripping knob mounted on the outer end of the shaft adapted for revolving the shaft, a pointer arm connected at one end to the shaft, said forward cover plate having graduations on its outer face over which the other end of the pointer arm is movable, a cylindrical valve slidably carried bythe rear cover plate and arrangedto open and close the ports, a
pin projecting from the valve medially the length thereof, an arm secured to the shaft and having a longitudinal slot receiving the pin to slidably actuate the valve upon a rotation of the shaft, said arm being disposed between said forward and rear cover plates, and a plurality of discharge ports in the lower end of the housing, said ports being formed in the respective rear and cover plates.
2, A mixing valve comprising a valve housin composed of two detachably connected sections, one of said sections having a pair of inlet ports, a slidable cylindrical valve in the housing having an undisturbed outer surface, said valve being supported on one of said sections, a chamber betweeneachport and the valve, said valve having straight ends movable across the respective chambers and said chambers having straight right angle walls to effect equal opening or closing areas in the chambers by like movements of the valve,
a shaft journaled for rotation on both of said sections, and an operating arm interposed betweensaid sections and projecting laterally from valve opening and closing equal areas of the chambers upon like movements of the operating means, said housing being composed of first and second detachably connected sections, theflrst section slidably supporting the valve, said arm being interposed betweensaid sections, said arm being disengaged from said valve and said shaft being disengaged from said first section upon removal of said second section from said first section FRANK J.
