Application fiiearebruar e, 1912. Serial No. 676,509.
To all whom z't'may concern 7 Be it known that I, .H owAnn KEYN'roN, a citizen of the United States, residing at West Hoboken, in-the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Valves for Radiators or the like, of which the following is a specification.
This invention relates to valves for use in connection with steam radiators or the like, and aims to provide certain improvements therein.
The object of the present invention is to provide a valve of simple and inexpensive construction which is adapted to be connected with a steam radiator, andto permit the slow passage of steam outwardly from the radiator, butto prevent the return passage of air intothe radiator when the steam is closed off from the latter. I v
The principal object of valves of this type is to prevent the filling of the radiator with air, which is required to be displaced when the steam is turned on. Moreover, if any air is present in the radiator the valve permits its escape as soon as steam is introduced into the radiator.
In the accompanying drawings illustrating the invention, Figure 11 is a ide elevation,with parts in section of one form of the invention; Fig. 2 is a vertical section thereof on line 2-2, Fig. 3; Fig. 3 is a top plan of the device, with the cap removed.
Referring to the drawings,the valve coinprises a casing A, the lower part of which is formed with screw-threads B, this portion being of suitable diameter to screw directly into a radiator X or a fitting connected with the radiator. The portion B is preferably tapered so that a leak-tight fit may be obtained without the necessity of a packing. The casing A is also provided with wrench faces such as C, by means of which the valve may be applied to the radiator. Above the wrench faces C is a portion'D which is preferably of less diameter than the screwthreaded portion B, and wrench face C.
The casing is provided with an internal bore E extending preferably the full length thereof, but also preferably of different d1- ameters. In the construction shown the lower part of the bore is of the maximum diameter and is formed with a screwthread F. Above the screwthread F is a restricted portion or shoulder G which serves as a seat for the valve seat H. Above the seat G the bore E is somewhat constricted, and at the top of the shell or casing it may be still further constricted as shown at I.
The valve which I prefer to use in c0nnec tlon w1th the casing is of the Schradertype, and comprises a valve proper J formed as a cup carrying a packing K of suitable material adapted to withstand a high heat and considerable pressure. The valve seat His of tubular construction, and is provided with a packing ring L which designed to" be pressed against the shoulder G by a screwthreaded plug M which is adapted to engage the screwthread F of the casing. The plug M and valve seat H are preferably connected together so that they can not become disconnected, and preferably also are relatively rotatable so that as the plug M is screwed inwardly the valve seat is not turned, but is pressed longitudinally inward. By this means the distortion of the packing L is prevented. To the valve proper J is fastened a pin N which passes through the valve proper, the valve seat, and the plug," the end of the stem being flattened as shown toprevent these parts from becoming disconnected, and to limit the upward movement of the valve. The plug is provided with screw-driver projections Y by which it may be rotated. V
At the tip of the casing I preferably provide a cap for the purpose of keepingdust or other foreign matter from entering the shell, and in order that the cap shall not prevent the escape of steam, I provide a passage through which the latter may escape, thus assuring that the radiator will always be full of steam whenever there is any pressure of steam in the radiator.. In the construction shown this is accomplished by making a flat portion or portions P upon the upper end of the casing, and preferably also notching the casing at Q, so that when the cap is screwed home, steam or air may escape downwardly around its edge.
By this invention several advantages are obtained. The valve shell is of simple and inexpensive construction. The valve parts are freely removable from the interior of the shell, so that in case of necessity they can be easily removed, replaced or repaired. At the same time as they are inserted from the bottom of the shell, they cannot be tampered with by children or others. This fea- .shown is particularly adapted for the purpose in question, since it is light in weight and positive in action. The restricted opening I at the top of the casing is suflicient to permit the slow leakage of steam, while in-- suiiicient to permit the introduction of any article which would be liable to injure the valve. The cap provides a means for excluding dust or the like, which in the construction shown is liable to enter the shell and injure the valve. At the same time a free passage for the steam or air is permitted.
Although I have described with great particularity an embodiment of my invention, I do not deem my invention necessarily lim ited to such precise form, as modifications may be made therein within the limits of the appended claims.
