T0 all whom, t may concern:

Be it known that I, IsAAc G.WA'rnRMAN, a citizen of the United States, residing at Santa Barbara, in the county of Santa Barbara and State of California, have invented new and useful Improvements in Electrical Mixing- Valves, of which the following is a specification.

This invention relates to electrlcalmixmgvalves.

The object of the present invention is the provision of an improved electrical valve mechanism especially adapted for use in con' iiuids by the use of' one electrical pushbut.

ton and the electrical operation of another valve of novel construction by another electrical push-button, successive manipulations ot' which gradually open or gradually close the valve to thereby obtain adesired mixture of the fluids or either of them separately.

The invention resides in the novel features and combinations of parts set forth indetail hereinafter and recited in the appended claims. ln the accompanying drawings, Figure 1 is a section on line D D of Fig. 5; Fig. 2, asection on line B B oi' Fig. 1;. Fig. 3, a section on line A A of Fig. 1; Fig. 4, asection on line E E of Figf; Fig. 5, a section on line C C of Fig. l, and Fig. 6 a diagram showing the electrical connections and push-buttons.

rl`he hot and

cold water pipes

1 and 2 lead into the supply-valve casing 3 through ports 4 and 5. The mixing-valve casing 6 has en,- try-ports 7 and 8, connected with exit-ports 9 and 10 in the supply-valve casing 3 by

pipes

11 and 12 and is provided with an exit-pipe Specification of Letters Patent.

ports 4 and 5 to ports 9 and 10 (sce Fig. 4) when the valve is open and to completely cut off the How of both hot and cold water when the valve is closed.

In the mixing-valve casing 6 is a tapered rotary valve 19, held in its seat by a spring- `pressed ball 2O in a socket in a removable vscrew-threaded closure 21,en tered in the valvecasing. The mixing-valve has a lune-shaped :..port or groove 22 in its side, which of suf lieient length to connect either port 7 or 8 more or less with exit-pipe 13 or connect both of said ports more or less with said exitpipe or altogether close communication between either port and the exit-pipe to entirely cut ofi1 the water. Accori'ling to the amount of rotation ot' this valve and the position it occupies, either hot or cold water will pass to pipe 13 in desired volume, or any desired admixture of hot and cold water can be obtained or the supply entirely cut otf though the valve 14 be open.

,The valve-

casings

3 and 6 have formed therewith the curved arms 23 (see' Fig. 3) and 24, Fig. 2, and the heads 2and 26 of the shell 27 of the

respective solenoids

28 and 29 are fastened to these curved arms 23 and 24 by screws 30. The solenoids are separately wound and separated by

heads

31 and 32 and intermediate insulation 33, while' the respective terminals 34 of

solenoid

28 and 35 of solenoid 29 are led out, as shown in Figs. 1, 2, and

Removable caps

36 and 37 cover the operative mechanisms at the upper and lower ends ot' the device.

heads

31 and 32 have

sockets

38 and 39, intol which iit the ends of

guides

40 and 41, which abut the inner faces ot'

caps

36 and 37.

The

valves

14 and 19 have stems 42 and 43,

which pass through

packings

44 and 45 and

glands

46 and 47, which hold the packings,

and said stems are centered in the

respective guides

40 and 41. The stem 42 has secured thereto a ratchet-wheel 48, whose teeth are arranged in four sets of three teeth cach, and

a square nut 49 is also secured on said stem. f

Through e stationary guide or bearii'ig 8O slides a push-button 8l. having a pivoted pawl SQ adapted -to engage a tooth ot' the ratchet-wheel 79. The button is normally pressed to the position `shown by :i coil-spring 83. lVhen the button is pushed in hy hand, the pawl engages a succeeding tooth ol the ratchet-wheel, and on releasing the button thespring 83 Snaps the Contact TH a quarterrevolution, causing two ot the points thereon to momentarily engage and then 'pit-:a olil the Stationary contacts. thus momentarily conipleting the circuit a`iid eiiei'gizii'ig the solenoid.
