VALVE.

Application filed January 2, 1919. Serial No. 269,336.

county of Montgomery and State of Ohio,

have invented certain new and useful Improvements 1n Valves, of which the following is a specification, reference being had' therein to the accompanying drawing.

This invention relates to improved valves and has for its particular object to provide an improved regulating valve for steam radiators.

An object of the invention is to provide a valve adapted for right or left hand, vertical or horizontal connections, being in effect interchangeable or universal in character and therefore adaptable to any standard form of radiator connections.

Our improved valve is also adaptable to the two general types of steam radiators, viz., single pipe system and double pipe system. As applied to the double type system the inlet port of the valve may be regulated by means of a handle having a pointer cooperating with a graduated scale. Thus the volume of steam passing to the radiator may be controlled, increased or diminished as may be desired. As used with a single pipe system the valve may be opened to full capacity and closed instantly merely by moving the valve controlling handle to the limits of its movement, respectively, which as here shown is substantially 120 degrees.

Various incidental improvements have been carefully worked out in the development of our invention which in their collective eflect tend to make the valve distinctly meritorious, especially as applied to radiators of the single pipe type. These features consist generally of ground-in joint construction which acts to prevent the escape of steam around the valve stem either as the valve is closed or open; the stufling box is so designed that it may be packed under pressure; the valve seat is disposed in a vertical plane and otherwise shaped to prevent the accumulation of foreign matter thereon and thereby preventing the proper functioning of the valve; the operable parts are essentially of simple, durable construction and of a character which will not be afl'ected by the corrosion of the parts or the action of the heat thereon, thus insuring the normal oper ation of the valve under all conditions.

Specification of Letters Patent.

Patented Nov. 18, 1919.

The valve is in the important particulars stated, an improvement of the type of steam radiator valve which provides for the introduction of steam and the simultaneous return of the condensation through the same port, the steam entering the valve through the upper portions of the port, and the condensed moisture being heavier than the steam, passing from the valve through the lower portion of the port.

In the accompanylng drawings, Flgure 1 1s a slde elevatlon of the valve with the operating parts horizontally disposed and showing in dotted lines portions of the interior arrangement of the mechanism;

Fig. 2 is a longitudinal cross sectional view of the valve with the operable parts vertically disposed;

Fig. 3 is a cross sectional view of the valve casing taken on the line 33 of Fig. 1;

Figs. 4, 5 and 6 are detail views, respectively, of the valve head or piston, the stem for controlling the same and the conical valve projection.

Fig. 7 is a detailed view of a valve indicator for determining the relative positions of the valve.

The valve casing consists of an integral housing 1, best shown in section in Fig. 3, provided with an extension 2 and intake aperture 3, threaded internally in the usual manner to be connected to the steam supply pipe; the valve casing being connected to the radiator by means of an externally threaded extension 4 and an aperture 5, the connection being made in any suitable manner as by a union consisting of a short section of pipe 6 and the adjustable nut 7. The valve casing is further provided with an extension 8 threaded internally and having an aperture 9 normally closed by a plug 10. Oppositely disposed projections 11 and 12 provided, respectively, with threaded apertures 13 and 14- are also provided in the valve casing, either one of the apertures being normally closed by a plug 15 and the other provided with adjustable nuts 1617 which are provided with apertures constituting a bearing for one end of the stem for regulating the valve piston. The nut 17 is threaded atone end to receive the nut 16, and at the opposite end to be secured to the casing 1, the central portion of the nut being hollow, as at 18, to provide a suitable stuffing bOXfOl' the valve actuating stem. A cap 19 is provided to add finish to the connection formed between the nuts 16 and 17.

The valve casing is provided with an internal chamber 20 merging at one end thereof adjacent the outlet aperture 5 into a chamber 21. At the juncture of the outlet 5 with the chambe 21 and integral with the casing-1 an annular wall 22 is transversely disposed between the wallsef the casing and is provided on the inner side thereof with a valve seat 23. Also extending inwardly from the casing 1 andintegral therewith are ribbed portions 2 1, the inner edges of Y which act as guides for the valve piston to ton consisting preferably of a composition disk 26 which acts to more effectually close the valve to prevent leakage thereof. At its opposite end the valve piston is provided with a shoulder 27 and a stem 28, the latter being adapted to enter and coiiperate with an aperturelO provided in the plug nut 10 which acts to guideone end of the valve piston. The valve piston is further provided through the body portion thereof with an oblong aperture 29 whereby ,the piston may be raised and lowered relative to the valve seat. d

When the valve is used in connection with a two pipe radiator system the piston head may be provided on the flat face thereof with a conical projection 26 detachably secured to the piston, as here shown, or made integral therewith; the tapered end thus formed acting through the operation of the valve controller handle to gradually increase or decrease the capacity of the port opening leading to the radiator. In single pipe radiator systems the valve piston head is preferably made flat to provide for quick opening and closing of the valve.

The valve piston is regulated by means of the actuating stem or shaft 30 which is provided with the crank oreccentric portion 31 adapted to cooperate with the aperture 29 of the valve piston to regulate the same relative to the valve seat. One end 32 of the valve actuating stem is adapted to be supported in a bearing 15 provided. in the plug 15. The end 30 of the valve stempro ects through nuts. 16 and '17 and has secured to its outerend in any'suitableinanner a controller handle 33 by means of which the valve may be regulated. At its central portion, adjacent one end of the crank portion 31. the valve actuating stem is provided with a tapered or cone-shaped portion 84-, adapted to cooperate with a corresponding depression 35 formed in the inner end of the nut 17 thus constituting a conical bearing and acting to more effectually prevent escaping of steam about the valve stem 30.

' From the foregoing description it will be clear that our improved valve is essentially a quick-acting valve, having a wide range of adaptability being practically universal with respect to standard radiator connections, either of single or double pipe radi ator systems. The construction of the valve is such that corrosion of the parts will not affect the free and easy operation thereof under all conditions, either under pressure or open. Opening and closing of the valve to full extent being accomplished by a slight movement of the controller handle, it. is obvious that animportant advantage is realized over types of valves requiring a number of turns of the valve stem to adjust the valve to full open and closed positions. In general construction our valve has been provided with improvements and refinements which together with the marked features of novelty result in a valve of superior merit, of simple, durable construction, of universal character with respect to its interchangeability and adaptability to various types of radiator construction.

In addition to its other important advantages, the improved valve is further especially adaptable to radiators inclosed by a grille or otherwise incased in such a manner that an ordinary valve would not be readily accessible and therefore could not be conveniently regulated. Vith the present valve this difliculty is readily met by merely lengthening the valve actuating stem to project through the casing of the inclosuro, this being made possible by the universal feature of the valve which makes it adaptable under a wide range of variable conditions.
