THEODORE H. SCHUTT, OF CLEVELAND, OHIO, ASSIGNOR TO THE BISHOP-BABCOCK- BECKER COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

RADIATOR-VALVE.

T 0 all whom t may concern Be it kno-wn that I, THroDoRE H. SoHUTr, a citizen of the United States, and a. resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Radiator-Valves, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as t-o distinguish it from ot-herinventions.

My invention relates to a t-hermostatically operated valve, which is adapted particularly for use in a two-pipe or separate return line steam heating system. It is capable, of course, of other uses, but itmay be vreadily attached to such a system, and permits automatic opening of the valve upon an excessive pressure being attained, as well as flushing of the valve by hand, when desired.

To the accomplishment of these and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing, and the following description, set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principal ot the invention may be used.

In said annexed drawing F igure l is a vertical central section through my valve, showing the key with which the liushing attachment may be operated, above the same; and Fig. 2 is a section on the line 2 2, Fig. l.

In Fig. l I show the external casing l, in which there is mounted a yoke member 2, having attached thereto a second yoke 3, which is formed with a circular slot l, running transversely and horizontally through the saine, and having a circular aperture 5 extending from the upper portion ot such slot. The lower pai't of the yoke is formed into an annulus which is adapted to scat upon the sides oit' the external casing at the point 7. A n aperture S extends vertically through this annulus, and upon the upper part of this apert-ure, a stop-per 9, attached to a thermostat l0, is adapted to To the thermostat l0, there attached an upwardly projecting member ll, bearing a ball l2, which has a projection 13 upon its upper surface.

The ball l2 is inserted in Specification of Letters Patent.

the circular slot 4, and the projection will fit loosely in the circular aperture 5. This will permit of a ball-joint movement sufficient to allow the stopper 9 on the thermo stat some play in all directions. This is desirable since t-he thermostat is formed of thin metal sheets which are not always of uniform thickness, causingthe disks to expand unequally at diiderent points, thus warping the thermostat and putt-ing the stopper slightly out of alinement with the seat. By giving the thermostat a ball joint connection and by forming the stopper pear shape, the valve will automatically aline itself upon acting.

The casing will be apertured at let, and will be externally threaded to permit of the attachment of the conduit l5. This attachment will be in the form of a ground joint, as shown. The casing will be apertured at its bottom for the purpose of at tachment to a drain. The member 3 has an annular, upwardly projecting extension 16, which is externally threaded, and is engaged by the collar 17. About this collar there is mounted a spring 1S, which presses against the removable cover 19, of the casing', and against the shoulder 2O on the neck 1T. Between the neck 1T and the member 3 there is attached a diaphragm 2l, which is held on its out-er edge between t-he cover 19 and the shoulder 22 on the body ot the casing. The top ot the cover is apertured, and the neck 1T is internally threaded, thus permitting of the engagement with this neck of a threaded key 23, shown above the valve. This key 23 has a shoulder 24k, which is adapted to contact the top ot the cover, upon the insertion and rotation of this key. The fluid will enter the valve casing through the conduit l5, and will pass around the yoke 2, and then out through the aperture S and the opening in the bottom ot' the casing. Upon the entrance of steam` the thermostatic valve 10 will be expanded, and since the pressure is prevented `from 'forcing the valve upward, by reason of the strong sgring 1S, the stopper 9 will be iorced downwardly, and will cont-act and close. the sea-t G. There is then no outlet from the valve casing, and it is desirable to provide means tor automatically opening some aperture, should the steam pressure within the casing rise to predetermined pressure. As the steam pressure increases in the casing, the diaphragm 21 will be forced upwardly, and will carry with it the yoke 2; thus lifting the annulus 6 from oft' the seat 7, and opening the passage directly from the conduit l5 to the opening in the bottom of the casing. The pressure at which this action will occur can be very accurately regulated by adjusting the spring 18.

rIhe valve can be made up for all types of systems, and by simply removing the cover of the valve and substituting a different spring, it can be adapted to operate at any desired pressure.

It will be noticed that the yoke 2 is spaced at its bottom portion from the bottom ot the Casing, thus permitting` the collection of dirt at this point around the opening in the casing. At .frequent intervals it will be desirable to remove this dirt, and this can be done most easily by simply lifting up the yoke and permitting the water to carry this dirt into the outlet pipe. By inserting the key 23 in the aperture in the top of the casing, and rotating it into engagement with the neck 17, the latter may be raised until it contacts the under side of the cover to the casing. This action will be readily understood, as when the shoulder on the key contacts the top of the casing, the latter will merely rotate in that position, and will gradually draw up the neck toward the top ot' the casing.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention l. The combination with a casing having inlet and outlet openings; of an apertured member snugly engaging said casing between such openings; a pivotally mounted thermostat; and a valve rigidly attached thereto and adapted to close the aperture in said member.

2. The combination with a casing having' inlet and outlet openings; of an apertured member snugly engaging said casing between such openings; a thermostat; and a beveled stopper attached to said thermostat and ball joint means connecting said thermostat and said member.

3. The combination with a casing having inlet and outlet openings; of an apertured member snuglyv engaging said casing be tween such openings; a thermostat; a pear shaped stopper attached to the same, and ball joint means connecting said thermostat and said member, whereby said stopper is adapted to be forced automatically into alinement and engagement with said aperture.

4. The combination with a casing having inlet and outlet openings; of a member having an aperture adapted to register with said outlet opening; a thermostatic valve adapted to close said aperture in said member and thereby said outlet opening upon the entrance of steam to said casing; and a `flexible diaphragm mounted in said casing and attached to said member, said diaphragm being adapted to operate upon the attainment of a predetermined pressure, thereby raising said member from said outlet opening.

5. The combination with a casing having inlet and outlet openings; of a member having an aperture adapted to register with said outlet opening; resilient means adapted to retain said member normally in such regg ister with said outlet opening; a thermostatic valve adapted to close said aperture in said member and thereby said outlet opening upon the entrance of steam to said casing; and a vflexible diaphragm mounted in said casing and attached to said member, said diaphragm being adapted to operate upon the attainment of a predetermined pressure thereby raising said member from said outlet opening.

6. The combination with a casing having spaced inlet and outlet openings and a thire opening spaced from said other openings; and a diaphragm mounted across said casing between said third opening and said other' openings; an internally threaded sleeve mounted on said diaphragm and adapted to register with said third openings when operated; thermostatic valve means mounted on said diaphragm and adapted to normally control communication between said inlet and outlet openings; and a helical spring disposed about said sleeve between said dia.- phragm and said casing and adapted to retain said thermostatic valve means in normal position.

7. The combination with a casing having inlet and outlet openings; of a member snugly engaging in said casing and normally closing the same, said member having an aperture; an automatically operating valve to control such aperture; and manually operable means adapted to move said member, thereby permitting direct eoinmunication between such inlet and outlet opening even when said automatic valve is closed.
