stem and aso duced threaded portion 27 of the upper valve stem part 28. A closed chamber 33 is providedv for carrying` a desired amount of volatile liquid 34: and has its upper wall, which is constructed in the form of a cor rugated 'diaphragm 35, connected to the upper part 28 of the valve stem, while 'the body portion of this closed chamber 33 is seen that the lower part 31 of the twoartvalve stem is formed in twoI sections'w ich are threadedly connected at 36 and are constructed in this manner for 4permitting the renewal of the valve portion 32 should the same become pitted or damaged in any way.
Received within the well 21 and engaging the bottom wall 21 of the same and the body portion of the closed chamber 33 is a spring 37 which operates to normally retain the valve 32 in itsI opened or unseated position.
The operation of this thermo-radiator. trap may be described as follows When the apparatus is properly adjusted for operation, the spring 37 will normally retain the valve 32 in its opened or-unseated position. The heating of the volatile liquid 34 within the closed` chamber 33 will cause the former to expand and this expansion will cause theV valve 32 to be forced against its seat 23.` Should the volatile liquid 34 be again cooled, by any means, the volatile liquid will condense and permit the spring 37 to dominate for again `unseating the `valve 32.
When live steam starts to enter the sectional radiator 5, through 4the steam pipe l6 and by the valve 7, the water et condensa tion and air within the various sections of the radiator will start to flow therefrom through the nipple 14; into the trap 9. rIhe volatile liquid 34, being in a cooled or thoroughly condensed state, the svalve 32 will of course be in its opened or unseated position and the water of condensation will flow into the pocket 19 until this is filled and will then overflow into the well 21 from whence it will be discharged into the return pipe through the opening 22;, the air being carried ol' .in the same manner. This action continues allowing air and condensation to escape through the return pipe until the condensation rises in temperature to a few degrees below the temperature of steam at atmospheric pressure. 7tft/'hen the condensation arrives at this'tei'nperature, it radiates its heat to the volatile liquid in the closed chamber 33, causing the same to form into a gas and thus exerting a pressure on the diaphragm 35 which results in forcing the valve 32 on its seat. A s condensation of a slightly lower temperature inds its way to the trap it radiates its lower temperature to the volatile liquid which quickly condenses and allows the spring 37 to lift the valve 32 whereupon .the radiator will be relieved ot' condensation. I
It is now believed that the construction and operation of this thermo-radiator trap will be understood from the above detail de scription and that no further explanation is deemed necessary. v
It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described the invention, I claim 1. In a device of the type described. a casing having an inlet and an outlet, a well formed in said casing communicating with said outlet, a valve for `controlling said outlet,- an annulary water pocket surrounding said well and overflowing thereinto, an expansible chamber operatively connected to said valve and having an annular extension depending into said water pocket for controlling the 4 operation of the valve, and means for normally .retaining said valve open.
2. In a device of the type described. a casing having an inlet and an outlet, a well formed' in said casing communicating with the outlet and located below the inlet, a valve for the outlet having a two-part stem, a water pocket in said casing below said inlet and overflowing into said well, an expansible chamber connecting the parts of 'said stem and projecting, into said water pocket, and means for normally retaining said valve unseated.
3. In a device of the typedescribed, a cas- ,inghaving an inlet and an outlet. a well formed in said casing communicating with the outlet and located below the inlet, a
llO
valve for the outlet having a two-part stem.
a water pocket in said casing below said inlet and overflowing into said well, an expansible chamber connecting the parts of said stem and depending into said water pocket, Vmeans for normally retainiiig said valve unseated, and means for limiting the distance to which said valve may be opened.
In testimony whereof I affix my signature.
JAMES J. LAl/VLER.
