` Application led March 20, 1902- Serial No. 99,079. (No model.)
To @ZZ 'wh/0m, it may concern:
Beit known that LGusfrivE A. SODERLUND, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Faucets, of
4 which the following is a specification.
This invention relates tocombination-faucets adapted to discharge water from two different sources of supply, one for hot and the `other for cold water.
lture of cold water with the hotwater discharged to prevent the possibility of a scalding eect.
Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of a faucet to which my invention may be applied. Fig. 2A represents a vertical section of the same.
sections showing the valves and their operating-cam in ditereut positions. Fig. 13 represets a vertical section showing the cam made tapering in form and vertically adjustable. Fig. 14. represents a section on line 14: 14 of Fig. 13.
The same reference characters indicate the same parts in all the figures.
In the drawings, 1 represents a central receiving or mixing chamber having a discharge-nozzle 2.
3 and 4 represent valve-chambers at opposite sides of the central chamber, said valvechambers being connected by necks 5 5 with the central chamber. pipe 6 communicates with the valve-chamber 3 and a hot-Water supply-pipe 7 communi-` cates with the valve-chamber 4. The Valve.
chambers are provided at their inner ends with valve- seats 8 ,8,A communicating with the necks 5 5, and at their outer ends with internally-screw-threaded openings formed and arranged to permit the insertion and removal of the valves -9 9. Said openings are closed by screw-threaded plugs 10 10, which are provided with squared sockets or guides 11 11, in which are loosely fitted the squared outer Figs. 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 represent horizontal A cold-water supplyend portions of the stems 12 12, affixed to the valves 9 9, said sockets preventing the valves from turning when they are moving to open and close the valve-seats. The inner end portions of the valve-stems 12 extend through the necks 5 and are fitted to slide in guideeyes 13, which are connected by arms 14 with Athe walls of the necks 5 and are separated from the portions of said walls at opposite sides of said arms by passages 15, through which water Hows to the central chamber when the valves are opened. The `valves 9 may be yieldingly held against their seats by springs 16.
17 represents a three-part cam which is located in the central chamber 1 between the inner ends of the valvestems 12. Said cam is formed ou a shaft or spindle 18, the lower endof which is journaled in a socket in the lower portion of the central chamber. The upper end portion of the spindle 18 passes through a stuing-box 19 on the upper portion of the central chamber and is provided with an external operating-handle 2O and with a pointer 2l, coperating with a segmental plate 22, which is concentric with the spindle 18 and is suitably inscribed, as hereinafter described, to indicate the positions of the spindle and cam required to draw cold and warm water and to permit the closing of the valves. The spindle is pressed downwardly into the socket which receives its lowerend by a spring 23, which is interposed between the top of a oavityin the stufng-box and a fiange 24 on the spindle.
The cam 17 has three parts or cam protuberances 171, 172, and 170 and is so formed and proportioned that when in the positions shown in Figs. 3, 7, and l2 its perimeter is out ofcontact with the valve-stems 12 and has no eect on the valves. `When the cam is moved to the position shown in Figs. and 9, the part 171 opens the valve of the chamber 3, which chamber receives cold water from the supply-pipe' `6, the valve of the Vchamber 4, which receives hot Water from IOO Figs. 5 and 10, the parts 171 and 172 open both valves, and two streams, one of hot and the other of cold water, enter the central chamber and are mixed therein, the resulting warm or tepid water flowing out through the outlet 2. When the cam is moved from the position shown in Figs. 7 and 12 to the position shown in Figs. 6 and 11 to open the valve of the hot-water chamber to its fullest extent, the protuberance 170 opens the valve of the cold-water chamber just before opening the valve of the hot-water chamber and holds the cold-water valve open to a limited extent so long as the hot-water valve is open, so that whenever the valve of the hot-water chamber is opened a sufficient supply of cold water will be admitted to the central chamber to temper the supply of hot water and prevent a discharge ot' scalding water from the outlet 2. A short movement of the cam from the position shown in Figs. 6 and 11 to that shown in Figs. 7 and 12 permits the closingof the valve of chamber 4, so that the water can be abruptly shut oft without returning the cam to the position shown in Figs. 3
which are directed outwardly toward the sides of the central chamber, so that the hot and cold Water is mixed in the central chamber before escaping through the outlet 2. This mixture is made more complete by the inner end of the outlet-nozzle, which projects into the central chamber and forms a curb 25, surrounding the entrance to the outlet, this curb causing a thorough mixture of the hot and cold water.
The inner ends of the valve-stems 12 may be provided with an tifriction-rollers 26, which bear on the perimeter of the cam and prevent Wear of the contacting parts. The squared sockets 11 and the squared portions of the valve-stems prevent the stems from turning, and thus preserve the proper relation between the rollers 26 and Vthe cam. These rollers may be omitted, however, if desired.
The cam is arrested in the positions shown in Figs. 3, 7, 8, and 12 by means of a stop 27, affixed tothe central chamber, and stop-arms 28 29, axed to the cam-spindle. The arm 28 abuts against the stop 27 when the cam is in the position shown in Figs. 3 and 8, and
the arm 29 abuts against said stop when the cam is in the position shown in Figs. 7 and 12.
It will be observed that the arrangement of the Valves is such that the pressure of the water inthe valve-chambers holds the valves against their seats, so that the springs are not essential when the pressure is relatively high.
In Fig. 13 I show the cam 17 made tapering in form and vertically adjustable, so that the quantity of water admit-ed to the discharge-nozzle 2 from the supply-pipes 6 and 7 may-be varied by adjusting the cam vertically. When the cam is in its lowest position, as shown in Fig. 13, it permits the minimum opening of the valves 9 9, and when it is raised from said position its tapering form permits a wider opening of the valves, the
v'extent of the opening of the valves depending on the height of the cam. The stem 18 is provided at its upper end with a yoke 180, having a slot 181,which receives the wrist portion of a crank 182, formed on or attached to the handle 183. Said crank is journaled in a casing 184, which is rotatable with the handle and with the stem 18. The handle is rotatable on its own axis to vary the height of the wrist portion of the crank.
I claim- 1.
