ELECTRIC VALVE-CONTROLLER..

SPECIFICATION forming part of Letters Patent No. 443,789, dated December 30, 1890. Application led Apri1'4, 1890. Serial No. 348,619. (No model.)

To all whoml zt may concern:

Be it known that I, CHARLES E. ONGLEY, a citizen of the United States, residing at New York city, in the county and State of New York, have invented an Ilnprovementin Electrical Valve-Controllers, of which the follow ing is a specification.

The object of my invention is to control a comparatively large valve which is moved by fluid-pressure through the agency of a second valve, which is moved bythe power of a magnet in a suitable electric circuit; and the invention consists` in certain arrangements and combinations hereinafter described and claimed.

The accompanying drawing is a central section through the apparatus.

1 is the main valve, and 'consists of a central stem provided at each end with a screwthreaded extension. On the lower extension is a cup-shaped piece 2, carrying a suitable packing, which when the valve is closed rests against the valve-scat 3. The cup, and hence the packing, is of greater diameter than the valve-seat, so that the packing rests squarely and firmly thereon. The extension also carries a lock-nut 4. AAround a socket in the cap into which the extension projects, and pressing up against the cup 2, is a coiled spring. On the upper extension of the valve is a second cup-shaped piece, which is preferably larger than 2, and which fits as a piston into the tube 5. This cupis provided with a packing 6. Over the piston-head 7 is a washer or packing 8, preferably of leather, and over this a retaining-nut 9 and lock-nut 10. Through 7, 8, and 9 are holes placed in line and preferably provided with a hollow serew-threaded bushing 1l, which serves as a permanent exhaust for the purpose hereinafter described. A branch pipe 11 is attached to the chamber under the piston and conducts the escaping water. The upper end of the tube 5 is closed by a nut-cap 12, which may havev a cock attachment, as also may the tube below the second valve. The valve is normally held up against the seat 3. by the spring.

13 is the water-inlet. When the valve mechanism. is attached to a water-supply, water flows into the space 14 below the main valve and into the space 15 below the second valve.

The Water-pressure then combines with the spring to hold the main valve closed.

The second valve in the preferred form consists of a stern 16, which passes through a packing to the outside of the valve-chamber. At the inner end of lthe stem is a cup-shaped nut with a packing 17 and with locking-nuts. This valve is held closed by spring 18, and when there is water in the space 15 by waterpressure. Stem 16 carries a nut 19, having on its upper side a socket 20, into which socket passes loosely a rod 2l, which is supported in a bearing E22 andbushingfl. A pin 21 rides in a slot 25 in the upper end of the bushing as the rod moves up and down. This serves to prevent the rod from turning, and thus keeps the armature 2G carried thereby in line with the magnet-poles.

27 is an arm or bracket having atits upper end an adjusting-screw, and between a nut thereon and the armature is a spring 28, the

tension of which is opposed to that of spring 18 and the water-pressure, but 'is insuicient to overcome the latter. The magnet 20, only 011e limb of which is shown in the drawing, may be in any desired circuit. If, for example, the outlet-pipe 30 leads to the normallyempty house-pipes in a fire-extinguishing system, the circuit might run through and to the thermostat of such a system, or it might run to the oice or other point where an alarm would be received and where the person in charge could operate a circuit-controller manually, if he found it necessary; but I do not claim, specifically, these uses of the valve, and I do not limit myself to such uses.

The operation of the apparatus is as follows: XVhen the valve mechanism is in place, water under the desired pressure occupies the space below the valves, and when the circuit of the magnet is closed or varied by a thermostat, by hand,or otherwise the armature, co-operating with spring 2S, opens the second valve, admitting water to the space above the piston-head of the main valve. This head being larger thanV the opposite one the valve is moved, thus allowing water to pass from the inlet-pipe directly to the outlet-pipe 30 and to the place of use. The main valve will be held in this position as long as thc circuit IOC is maintained in operative condition. From the space above the main valve water escapes through the hollow bushing sufficient rapidityto prevent the water-pressure from moving the valve. The object of this escape is torelieve the pressure above the valve after closure of the second valve, so that 4a further downward movement of the valve,

and to provide for this movement is the 0b ject of making the valve-stern and the armature-carrying rod in two parts connected loosely at the socket 20. In order to get the desired power from themagnet to operate the valve, the armature is placed quite near to the poles and when attracted is brought against the poles. Notwithstanding this fact, the valve can be still farther moved by hand or otherwise, owing to the loose connection described. l

It. will be clear that the arm 27 and spring 28 may be omitted, provided a magnet of suffcient strength is employed. Certain other of the features described may be varied without departing from my invention.

Having thus described my invention,wl1at Il claim is-` 11, but not with;

1. The combination, with a main valve operated by Huid-pressure and controlling the passage between an inlet and outlet pipe, of a second valve. controlling a passage leading from the inlet-pipe to a space above the main valve to'open it, a magnet, an armature for the magnet, to which is connected a rod, and a valve-rod for the second valve meeting the the armature-rod, but having no positive connection therewith, whereby the valve and rod may be moved by the armature or independently thereof, substantially as described.

2. The combination, with a valve held closed by Huid-pressure and a co-operating spring, of a magnet and co-operatin g spring for opening the valve and -a loose connection between the valve-stem and the armature-rod, substantially as described.

3. Theicombination of a valve and stem, a spring holding said valve closed, a rod loosely connected to the stem, movable in a bearing, and carrying an armature, a magnet, a bracket, one end of which terminates adjacent tothe armature, and a springA between the bracket and armature and r(zo-operating with the magnet, substantially as described.

Correction Letters Patent No.443,789.V

It is hereby certified that Letters Patent No. 443,789, granted December 30, 1890, upon the pplicaton of Charles E. Ongley, of New York, N. Y., for an improvement in .Electric Valve-Controllers, were erroneouslyjssued to said Ong-ley as sole-owner of the invention; 'that said Letters Patent should have been issued to said Charles E.

Ongley and Thomas W. Robertson, jointly; each being owner of one-half interest, as shown by the record of assignments in this 'ce; and that seid Letters Patent should be read with this correction therein that the same mayconform to the recordv of .the case in thePatent'pfee. l
