To all whom it may concern: 1

Be it known. thatI, Louis RICHARD Hmeaxn, a citizen of the United States, residing. at Los Angeles, in the; county of Los Angeles have-invented a new and useful Faucetmf'whi'ch the follow-- ing is a. specification. I

This invention relates toa faucet and particularly pertains to a. faucet embodying an electric liquid heating element.

It is the object. of .this invention to provide a faucet having. a liquid controlling valve, anele'ctric heatingclement, and .a cir-- 'cuit making device adapted on disposing the valve in certain pos tions to direct. currents through the heating element, and by means of which cold, warm or hot water maybe delivered from the faucet by turning the A further object is to provide a construcion and arrangement whereby cold water is directed to the heating coil immediately pre ceding thecompletion of the electric circuit through-the coil and immediatelyiollowing 25 thebreaking of said circuit, so as to insure the coil being completely submerged while the, electric currentis passing-,therethrough, thus protecting the coil against burning out;

Another object is-to provide awater heat-. ing 'faucetin which thewater discharged. therefrom may be heated to various degreesof temperature starting from that of the cold, water delivered from the service system and gradually 'ncreasing to the boiling point. I v 1 provide afaucet of Another object ism the above character which may bereadily,

in which the valve is partly-opened to' per nutwater to pass therethro'ugh immediately before completing the electric circuit and end to receive internally threaded end caps '7 and 8, the end Walls ofwhich =caps are spaced from the end faces -ot the wall '6 to form: a water compartment 9 and' an air conlllpartment J10 on opposite sides: of'thewa. The.f wall 6 is formed withan axial ta-- peredr-borein'whi'cha'rotary val've"l1 is mounted, the valve having a stem -l2"-whi'ch across the" compartment ij 10' and through the end cap Sand hasa handle 13 aflixedto its outerend; A packing gland 14, threaded on a, bossi'formed on the-wall projects encompasses the end of the valve 11 to hold the latter-in its seat to prevent leakageinto the. chamber 10. As a means-forjdraining the chamber 10 .inieventleaks should occur,

a drain aperture 15 is formed in the lowerwalljof the cap 8. A radial duct 16 is formed in the wall fiffleading from its outer face to the valve; the-outerend of the duct being internally threaded to connect with a supply pipe 17. a 7' v The valve is formed-,with-a longitudinal passage 18 which opens at one end to the chamber 9. A pair of ports 19 and 20 are formed; the valve wall and spaced apart eripherallythereof and-so positioned as to moved in and out of register withthe inner end of the duct 16. The ports are spaced-in peculiar relation to each-'otherand 'toa circuit make and break device as will be later. described:-

A discharge passage wall 6.;radially thereof and preferably' arranged-tinalinement with the duct 16"andwhich passage is internally threaded {on its outer-end to.receivega; nozzle 21. I The passage; 21 1 communicates with the chamber .Qthrough-hn opening 22 which passes through a'boss 23 forming'a seat for aZ packing-ring or gasket 24.

Mounted withinthe chamber 9 is an in Patented Feb; 25, 191$ the 1ine 55 of "Fig. 2 showing 21 is formed-in the sulating member-preferably formed of porce- I lain and comprising an annular wall arranged to extend adjacent the end taco of the wall 6 and to encircle the inner end of, the valve, and which wall carries concentrlc flanges 26 and 27 on its inner and outer margins. The outer edges of the flanges 26 the ange 26. The orifice 30 is disposed in the lower portion of the flange so as to lie below the discharge. opening of the valve.

The chamber 29 communicates with the dis charge passage 21 through an opening 31 registering with the opening 22. The openings 31 and 22 are preferably of a diameter less than that of the intake duct 13 so as to restrict the flow of liquid at this point. The gasket 24 is interposed between the walls 6 and-.25 around the openings 22 and 31 so as to prevent the flow of liquid from .the valve from passing behind the wall 25 and out the opening'22. This necessitates the passage of the fluid through the annular chamber 29.

' Arranged within the "chamber 29' is an ar-l cuate heating coil 32 the terminals of which connect; with binding posts 33 and 34 car ried by;' the wall 6 and'extending through an opening 35 in the insulator wall 25. The binding posts 33'a'nd 34 are preferably arrangedto extend below and. on opposite sides of the orifice 30 and pass through and are insulated from the wall 6.

The binding post 33 is formed with a threaded end projecting into the chamber 10 on which is screwed a nut 36 engaging a conductor 37 leading to one terminal of a generator 38. The binding post 34 is also formed iwith a threaded end to receive a nut 39 engaging an S-shaped spring contact member. 40.

A third binding post 41 is arranged in the chamber 10 and engages a second S-shaped spring contact member 42 spaced from the contact 40. A conductor 43 leading from the other terminal of the generator 38 con:

nects with the post 41. The conductors 37 and 43 may pass through the drain opening 15 as shown in Fig.5.

It will now be seen that by connecting the contact members 40 and 42 a circuit will be completed through the heating coil 32.

As a means of completing. this circuit I have here shown a pair of blade wiper contacts 44 mounted on the valve stem 12 and insulated therefrom and 'so arranged there on that when the valve stem is turned these contact memberswill engage and electrically. connect the contacts 40 and 42 at a proper indicia.

Normally, the handle points downward,

time in relation to the opening and closing of the valve ports as will presently be described.

The outer end face of the cap 8 is provided with indicia designating the position of the valve for delivering cold, warm or hot water and for denoting when the valve is closed. The valye stem is fitted with a pointer, in this casethe handle 13se rving the purpose,which is so arranged in relation to. the ports in the valve as to indicate the position of the valve ports and the switch when pointing toward the various as shown in Fig. 1, toward the indicia Off and when so positioned'the valve will be closed and the circuit through the heating element broken.

In the operation of the invention when it is desired to deliver cold water the bandle is turned upward either to the right or left to the indicia Cold tion the handle horizontally and move the valve a one-fourth turn. If the handle and valve is turned upward to the right the port 19 will move into register with the inlet duct 16 so that cold water will pass through the valve and out the nozzle at a maximum pressure. If the handle .and valve are turned upward to the left the port 20will be about half open to the duct 16 when the handle is disposed horizontally. When the valve ports and handle are positioned as just described the switch contact member 44 will be disposed so .as not to connect the contacts 40 and '42.

When it is desired to deliver warm water the valve is turned to the left to dispose the handle above the indicia Cold, for example, pointing toward the indicia 77' be positioned as indicated by the dotted line a in Fig. 4-so -as to connect contacts 40 and 42 and direct current through the'coil 32. The port 20 will then be wide open so as to deliver cold water to the heating coil at a maximum volume. The heating capacity of the coil is such that when the maximum amount of liquid is passing through the faucet the liquid in rapidly flowing around the coil will be slightly heated.

When it is desired to increase the temperature of the liquid, movement of the valve is continued to the left to partly close port 20 and diminish the volume of liquid flowing around the coil. When the handle points toward the indicia Hot the parts will be positioned as shown in full lines in Fig. 4 with the port 20 sufiiciently closed so that the liquid will pass slowly around the coil and thus be heated to its maximum temperature.

To shut ofi the hot liquid it is necessary to either retract the handle or continue its which will posi-.

' The contact member 44 will then movement to the right, past the Cold indicia to the OE position. In either event the ports 19 or 20 will remain open immedotted line b in Fig. 4.

diately after the contact member 44 moves out of engagement with the contacts'40 or 42 when cuttin off the current through the coil so that col liquid will flow through the faucet around the coil immediately after cutting the current to the latter. The partly open position of port 20 when the contact member 44 is out of connection with the contact members 40 and 42 is indicated by the In turning the valve far enough to completely cut off the flow of liquid through the faucet, disconnection of the electric circuit through the coil is insured, as the contact member 44 breaks the circuit when the flow of liquid through the faucet ceases.v This,

after flow of cold liquid ceases, also insures the coil being submerged at all times and also cooled, thus protectingfit against being burned out which might occur if the coil were exposed to the air. The openings 31 and 22 are arranged at the'top of the coil and the discharge nozzle leads from the up-- per portion of the casing so as to insure against drainage of the compartment housing the coil, and to prevent the formation of an air space above the coil to insure the latthe length of the coil to pass out the discharge opening, thus thoroughly distributing the liquid around the coil so as to be acted on by the entire heating length of the latter.

While I have here shown and described a specific embodiment of my invention, it is manifest that various changes may be made in the details of the construction without departing from the spirit and scope of the invention'as set forth in the appended claims.
