auroma'rrc VALVE.

Application filed m is, 191%. Serial No. maosa.

To all whom it may concern:

w, controlling the supply of steam to a, steam heating radiator.

My invention has for its object to provide a valve which will automatically control the supply of heating fluid to a heater and which isadapted to be automatically operated by a thermostat in accordance with the temperature conditions in the apartment to be heated.

In effectuating this object vmy invention consists in the provision of a magnetlcally operated valve which is specially adapted for application to a steam heating system, and which is adapted for use in connection with a thermostat whereby the same is operated in accordance with the temperature in the said apartment.

My invention in one adaptation thereof is illustrated in the accompanying drawings, wherein Figure 1 is a perspective vlew partly in section of an apartment having a steam heating apparatus equipped with. my in vention. Fig. 2 is an enlarged vertical detail section of my invention applied to a steam heating pipe.

I have illustrated my invention as applied to a car, wherein steam is supplied from the train-pipe A and is conducted through the branch B which passes through the floor C of the car to a radiator D. A hand valve E is represented as being applied to the pipe B for the purpose of shutting down the supply of steam when desired. The exhaust from the radiator is discharged through a vertical trap which may have the usual thermostatically controlled outlet F situated below the floor of the car, and the usual blow-ofi' valve G. At a suitable point in the pipe, as for instance in the inlet pipe, is situated the means for controlling the heater, and in this case these means are adapted tocontrol the supply of-steam to the heater, although they might equally well be adapted to control the outlet from the heater.

In the form in which I have shown my invention an admission valve H is contained within a casing I and controls the supply of steam to the radiator. The means for automatically controlling the movements of this valve include a magnet which as a whole I designate J. The said magnet, illustrated in detall in Fig. 2, has the usual coil K surrounded by an iron casing L, and the center of the-magnet, which is hollow, receives a tubeM which, at its upper end, is threaded steam-tight to an upper iron ring N, which is also threaded into the outer casing L. This ring N is provided with recesses n by which it may be removed from its position when desired. The valve stem is formed in two parts 0, 0 which are separated at a median point 0 as illustrated. The lower part 0 of this valve stem is pinned by pin 0 to a spring cap P, and between this spring cap P and the valve seat Q; is coiled spring R, which normally holds the valve H in its upper or open position. The upper part 0 of the valve stem is threaded into the armature bar S, and is adjustably. supported thereon by means of the nut a, which is threaded onthe end of said valve stem. A bonnet T is threaded onto the upper part of the casing L and has a steam-tight connection therewith so as to prevent the leakage of steam at this point.

Means for shutting down the valve H when desired are provided, and the same include a bolt U which is threaded into the upper part of the bonnet T, and at the lower end has a cone valve u which bears against a correspondingly shaped seat in the bonnet, and provides means for preventing the escape of steam from the chamber when the bolt U is retracted. Additional means for preventing the escape of steam are provided consisting of a stuffing-box u A bonnet V provides means for connecting the tube M with the casing I of the steam pipe. For this purpose the said bonnet V is preferably provided with a depending threaded sleeve '0, which is threaded into a Specification ot-Letters Patent. Y pamm a Ja 11, 1916,

i the supply of steam, and these means, as i ortion and screwed into the bonnet V. his tube'has a small shoulder m at the upper end 'of the threaded port1on.' This shoulder m together with the stop a provide the means whereby'the adjustment of the magnet relative to the valve is maintained constant. For ease in taking the apparatus apart, as for instance, for the'purpose of repair or replacementof any .of theparts, I separate the valve stem into-two parts 0 O as illustrated, and this separation, which is illustrated at 0, enables the two parts to abut against one another so that the spring R shall move the upper partand the armature, and likewise that the movements of the armature shall move the valve H. At the same time the tube M may be easily removed by unscrewing from the bonnet V, whereupon the stem will separate at 0.

The valve proper is of usual construction and has a wearing face It, the nature of which will be determined bythe pressure to which it is to be subjected, and the attachment to the valve stem is in the usual manner.

' Means are provided whereby the magnet J is energized for the purpose of controlling illustrated, accomplish their object by causing themagnet to close the valve when the temperature in the apartment rises to a previously determined point. The magnet is included in an electric circuit X, which contains a source of electricity Y and a switch w. Also included in this circuit is a thermostat Z, which may be ofany desired construction, and as many constructions of thermostat are available for this purpose I have not thought it necessary to illustrate the same in detail. This thermo stat is adapted to open or close the electric circuit upon a change of the temperature in the apartment, and a switch :0 enables the circuit to be permanently opened or closed.

In the operation of my apparatus in the form in which the same is illustrated, when the temperature in the apartment rises to the predetermined point, the thermostat Z will close the circuit X and energize the magnet J causing the armature S to be attracted, thereby depressing the stem 0 O, and closing the valve H shutting off the supply of steam. When the temperature inthe apartment falls a suflicient amount the thermostat Z opens the electric circuit. X,

whereupon the sprin R pressing against the spring plate P will lift the valve stem and raise the armature. Steam will then be permitted to flow through the steampipes in the direction of the arrows.

When steam is being admitted to the radiator D it will leak around the valve stem and into the armature chamber. For

stem sufficiently to close the valve.

the purpose, therefore, of preventing the M escape of steam from the said armature chamber into the coils, I c ause the tube-M and the bonnet T-to be. steam-tight, and thering N likewise-hasasteam-tight fit,-whereby the steam is prevented from escaping from the armature chamber or the tube. When it is desired to permanently shut ofi' steam,'the screw bolt U maybe screwedv down until its face 14 depresses the valve stalling-box u will prevent leakage of steam past the said-screw bolt.

The adjusting nut .9 enables the height of the valve stem 0 to be adjusted relatively The to the armature S so as to at all times 1 obtain a tight closing of the valve H.

I have illustrated in the accompanying drawing the preferred form for my invention which is the best form now known to me, and this has been carefully described, but I. do not desire to be understood that I intend my invention to be limited strictly to all the details of construction therein illustrated and described, as the same may be varied and equivalent devices employed within the limits of'the appended claims without departing from my invention.

I claim as my invention a 1.
