To` all whom 'it may concern:

B'e it known that `I, ISAAC G. WATERMAN, a citizen of the vUnited States,residing at Santa'v Barbara, county of Santa Barbara, andy State of Californiayhave invented eertain new and useful Improvements in Electrically-Operated'valves, of which the fol? Y oeratingmechanism of novel construction w ich is s'elfvcontained and adaptedfor attachment to or detachment from the valvecasing containing an l automatically'. closing valve, so thatthe valve-shell with its contained valve'can be originally tted by a plumber Iand electrician 'can afterward apply the electrical part ofthe valve and an automaticA mechanism of improved and'nove'l construction adapted'to automatically open thevalve on a .given electrical energization of the coil or solenoid and to close thevalve on a succeeding electrical` energization, said o erating mechanismbein so constructed t atyit is absolutely rel'abe inw/action and will not get out of order froin wear, or catch, or Otherwise become deranged. i Another objectis .to provide an indicatqi ada "ted teshow whether` thevalve isi open The present electricallygoperated .valve is .whe;e.th'e.pressure is very high, but is so. aclustqlg.' that it.

The valve-casing 1 is of an ordinary type. In the bottom of the valve-casing is a removable screw-plug 2, in a 'pocket in which Aslides the lower part 3*? of valve-stem 3, care rying the valve 4, which is 'adapted to iit the seat 5 inthe .valve-casing 1. The stem 3 passes through a gland or stuffing-box 6. A. coil spring 7 encircling stem 3' and inter-V posed between the valve l.tand the plug'2, tends to seat the valve.

- As thus far described, the valve is adapted to be inserted in any water, steam, or air .by a'plumber or and the .electrica operating mechanism l of the valve may be laced in position later by an electrician. Iihwever, the entire valve mechanism in section; Fig. 4, a lan view. of

' he valve-operating mechanism is sup-Y ported by a spider 8 which fits over a :boss 9 on valvefcasing 1 and is .held thereto by screws 10. Screwed at' 11 to thespide-r 9, .is a metal shell12, which incloses the operating mechanisms and has at its upper end a detachable cap 1 3 provided with "a slotglli,

This releasmg plate has an opening 32 ada tedto re- 5 ceive the reduced tip 33 on the va veoperat ing rod 20 when the parts are in the position shown in Fig. 2, thus permitting spring 7 to close the valve 4.

Securedto the armature 13 and passing loosely through holes in the guide-plate 24 are two sets of pins 34 and 35. The pins 34 are bridged by a kicker-plate 36 and the pins -35 are bridged by a kicker-plate 37, said kicker plates having the respective notches 15 38 and 39.

tion shown in Figs. 1 and 2.

The slide 27 is provided with two sets of ears 42 and 43, located between and pivoted to which on the pins 44 and 45, are the pawls 46 and 47, which have slightly rounded free ends 48, the toes of these pawls being adapted for reception in the notches 38 and 39 and foralternate engagement with the edges 49 and 50 ofthe kicker- plates 36 and 37, accord,- ing to the position of the slide' 27. These pawls have lat surfaces, against which bear the free ends of a leaf spring 51,whose center part is bent and received in a notch in the vslide 27 between the pawls. The form of spring can be changed, the purposeof the 35 spring being to hold the two pawls in their upwardly inclined positions so that they will be adapted for engagement by the edges 49 a'nd 50 of the kicker plates, the pawl 46v being engaged on a given energization of the arma- 40 ture, and the pawl 47 ona succeeding energization, to shift the slide 27 one way or the other to cause opening or closing ofthe valve. A fourlegged frame 52 has its legs secured to the pivots 44 and 45 and carries an indi- 45 cator-plate 53 bearing the words "On and OH which are adapted to be displayed through the sightopening 14, according to the position of the slide 27.

Assuming the valve is closed, as shown in Fig, 2, when the solenoid is electrically energized, the armature 18 is attracted very strongly to thepolar faces of the coil and has to move but a slight distance` to accomplish opening of the valve. The pins 34 and 35 Iand the tube 19, being connected to the armature, when the latter is attracted, the engagement of the tube 19 with the head 21 causes the valve-stem 3 to be pushed downwardly and the valve 4 to be opened, the r'educed end 33 being withdrawn `from the op'ening 32. Simultaneously with this operation,

- the edge 49 of kicker-plate 36 by its engagementwith the toe 48 of pawl A6, shiftst e slide 27 to bring the parts in the pos1t'1on shown in Fig. 1, thus positioning the pawl 47 i l x energized, whereupon the armature is again attracted and, by the engagement of the edge 5() with pawl 47, the slide 27 is shifted to the position shown in Fig. 2, which brings the opening 32 in position to receive the reduced end 33 and permits spring 7. to close the valve, the Oil sign of the indicator being l then displayed through sight opening 14.

Instead of having the opening 32 in the I slide 27 (although such a construction would be entirely operative) it is preferable to have the opening 32 in the releasing plate 30, which is independently movable by spring 31, so that shifting of the slide 27 before the tube 19 has disengaged the tip from opening 32 will'not check or derange the operation ofthe parts, the spring 31 permitting the engagement to continue while the slide 27 is being shifted.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v 1. In an electrically operated valve, the` combination with a valve casing and valve in said casing, of a single electro-magnet having a magnetizable polar member and located outside the valve casing, an armature disposed closely adjacent the polar member aforesaid without intervening obstruction in the air gap therebetween, said valve being separate from the armature but operable thereby, means for operating the valve from the armature, and shiftable valv e-controlling means located outside the valve casingand on theopposite side of the armature from the air gap aforesaid, said means being operated l lOll by the armature to automatically control the operation of the valve from the armature, whereby the opening and closing of the valve vis automatically accomplished on alternate electrical energizations of the single electromagnet aforesaid and the armature and controlling mechanism are unaffected by the pressure of the fluid in the valve casing.
