UNITED STATES PATENT OFFICE- MARY A. KISSELL, OF CHICAGO, ILLINOIS, FOR HERSELF AND AS EXECUTRIX OF ABRAHAM S. KISSELIJ, DECEASED.

ELECTRO-AUTOMATIC VALVE.

SPECIFICATION forming part of Letters Patent No. 415,871, dated November 26, 1889.

Application filed March 21, 1889. $eria1 No. 304,219. (No model.)

To all whmn it may 007200772: L Be it known that ABRAHAM S. KISSELL, late a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, now deceased, and MARY A. KIssELL, of said Chicago, did, during the lifetime of said ABRAHAM S. KISSELL, invent certain new and useful Improvements in Electro-Automatic Valves, of which the following is a I0 specification.

Said invention is an improvement upon the device shown in Letters Patent of the United States No. $354.2, issued June 15, 1880, and relates to means whereby a valve which is used to control the flow of steam, air, water,

or gas through a pipe is opened or closed automatically by the admission of a fluid under pressure alternately above and below a piston connected by a suitable stem to the valve, said piston being located in a pressurechamber, and the supply of actuating-fluid being regulated by the movement of an auxiliary valve or plunger in a supplemental pressure-chamber, said plunger having its 2 5 movements controlled by electrical devices connected in circuit with a suitable thermostat or a similar appliance, adapted to close the circuit and thereby actuate the device.

In carrying out this invention some of the 0 principles described in said patent are utilized, among others that of operating the valve by means of the difference in area of its two actuating-surfaces; butin this construction the valve is not connected directly to the ar- 3 5 mature, and the movements of the valve are performed solely under the influence of the fluid-pressure, the electrical devices being used only for the purpose of closing and opening the fluid-ports.

0 The invention consists in the novel constructions and combinations hereinafter described, but particularly pointed out in the claims.

In the drawings, Figure 1 is a side eleva- 5 tion of a section of pipe havinga valve-charm ber formed therein, and showing also a steamcylinder, exhaust-chamber, and operatingmagnets. Fig. 2 is a central vertical section of the device shown in Fig. 1, some of the parts being in elevation, and showing, also, the. thermostat and electrical connections. Fig. 3 is an elevation of the device shown in Fig. 1, except that the casingsurrounding the low, as shown in Fig. 6.

mounted.

magnets is in section and the View is from the opposite side. Fig. 4 is a similar view of the device from the side indicated by the arrow, Fig. 1. Fig. 5 is a plan view of the magnets, the casing thereof being removed. Figs. 6, 7, and 8 are details.

Referring to the accompanying drawings, A is the valve-chamber, having a suitable seat formed therein and in open communica tion with the supply-pipe B.

a is a threaded flange, to which the fluidoutlet pipe is joined.

C is a valve, which may be of any suitable form, and in this construction the valve-stem 0 is projected upwardly into a cylindrical pressure-chamberD, and is connected therein to a piston E, the reciprocation whereof under the influence of steam or other fluid under pressure eifects the seating and unseating of the valve, and thereby the flow of the motive or heating liquid.

F is an auxiliary pressure-chamber, havin g, preferably, a cylindrical shell G therein, within which reciprocates a plunger H, whose stem h is connected to the armaturel of mag net J J The shell or casing G has apertures g, which register with apertures d in the Wall of the cylindrical chamber D. Said shell is also provided with apertures g, opposite the apertures g. The plunger G has peripheral grooves G toward each end thereof and is 1101- Transverse apertures g are formed, respectively, above and below the peripheral grooves G, whereby a fiiuid under pressure may escape from the hollow of the plunger through said apertures 0 and through the aperture d into the pressurechamber.

F is a fluid-supply pipe communicating at one end with the supply-pipe B below the valve-seat, and at the other with the hollow of the shell G, whereby said hollow is kept filled with live steam or other fluid under pressure. A suitable waste-opening, as f, will be formed in the bottom of the chamber F, and the liquids formed by the condensation of vapor therein will be conducted thence and suitably discharged.

In Fig. 5 is shown in plan view a pair of electro-magnets J J, and the armatures I I of which are connected to bars K K, pivotally L is a plate of insulating material,

bearing upon the upper edge thereof springcontacts 1 Z, whose ends are preferably passed by each other and curved, as shown. A short arm 70, depending from one of the bars K, carries a rigid lever K, which is adapted to rock an arm M, pivoted to the back of plate L. Arm M has an angular extension m, which is adapted to ride upon the curved ends of the spring-contacts Z, so as to direct the circuit through the one or the other of the pair of magnets. By these means the magnets are kept ready to receive the current whenever the actuating-needle of the thermostat closes the break thereat, while at the same time the electrical energy-is conserved and is expended only when the temperature varies sufficiently to make action necessary. The magnets will form part of electric circuits provided with a battery Y, of suitable strength, and a thermostat T or other appliance will be joined in the circuits in the usual manner, so as to complete said circuits whenever the temperature of the locality of the thermostat passes predetermined points. The thermostat may be of the sort shown or such as described in said prior patent, or of any other improved form. The electrical connection will be readily supplied by a person skilled in the art. The

' wires N N join to the hot and cold sides of the thermostat the magnetsJ J, respectively, and the wire 0 joins the metallic pivot of arm M to one pole of the battery, the opposite pole being joined to the thermostat in the usual manner.

The valve is operated in the following manner: When the temperature of the apartment containing the thermostat or other circuitclosing device has passed the point at which said device is set, the electrical circuit is closed,

whereupon the magnets J will attract the armature I and cause the reciprocation of the plunger in such manner as to admit steam to the upper side of the piston E, which being of greater area than the valve B, said valve will be seated and the supply of steam or other motive fluid cut off. \Vhen the temperature has fallen sufficiently to cause the deflection of the needle of the thermostat to the opposite side, the contact is made and the current directed through the magnet J, attracting the armature I and causing the reciprocation of the plunger II in the direction to admit steam to the lower side of the piston E, and by its expansive force acting 011 said piston, unseating the valve and permitting the flow of the steam or other fluid through the outlet-pipe to the radiator or other ultimate destination. In these operations the steam is alternately admitted above and below the piston E, and it will be observed by reference to Fig. 2 that when the apertures of the plunger, shell, and wall of chamber D register on one side of the piston apertures of the chamber, wall, and shell and the pe ripheral groove of the plunger on the other side of the piston also'register, whereby the steam or other fluid of that side may exhaust into the chamber F and the condensation of the vapors of the fluid occurs in said chamber. The provision of this exhaust-chamber obviates the cushioning of the piston,whereby the free action of the valve would be interfered with, and this feature is found in practice to be of great utility.

In Fig. 8 is shown a form of plunger which I find it expedient to employ where the fluid used is under high pressure. In this form of construction the peripheral groove is interrupted,theplunger-wallbeingmade thin. Said wall is slotted longitudinally at h, so that a limited amount of expansion and contraction of the metal of the plunger does not disturb the accurate fit of the latter to the bore of I the shell.

It is obvious that modifications of the described construction may be madeas, for example, in the form of the piston and of the auxiliary valve or plunger, as well as in the construction and arrangement of other parts of the device. The specific device shown in the drawings is intended to be used to control the supply of heat to radiators, steamcoils, &c.; but the invention is applicable to a variety of uses. I

The electric-switch device herein described and shown was the sole invention of said ABRAHAM S. KIssELL, deceased, and is not claimed, broadly, herein, but is claimed in a separate application filed in the United States Patent Office August 31, 1889, Serial No. 322,688.

I claim 1. In an electro-automatic' valve, the combination, with the valve and an actuatingarm moved by the'oscillations of the arma- I ture and adapted to engage said spring-contacts alternately, whereby to direct the current through the magnets alternately to cause the-reciprocation of the auxiliary valve, sub stantially as described.

2. In an electro-automatic valve, the combination, with the valve, of a piston of greater area connected to said valve, an auxiliary valve comprising ahollow plunger hav' ing suitable ports and reciprocating within an inclosingcasing having apertures communicating with the plunger-ports and leading to the piston-chamber, a pipe to supply a fluid under pressure to the hollow of the plunger, and an electro-magnet whose armature is adapted to operate the plunger, substantially as described.
