radiators in order that overheating of rooms may be prevented in moderate weather.
A further object is to provide means that can be employed in connection with automatic venting mechanism and Will permit the free escape of air when the said automatic mechanism is in operationl The preferred form of construction is illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional view through the novel structure, showing the internal parts in elevation. Fig. 2 is a similar view, but illustrating the internal mechan ism in section. 1
Similar reference numerals designate corresponding drawings.
In the embodiment illustrated, a casing 3 is provided having an inlet nipple 4 on one side and between its ends that can be screwed into an ordinary radiator. The body of the casing is provided wit-h a removable bottom 5 and a cap (5 that may be secured thereto in any suitable manner.
The casing is provided in its upper end with a conical reentrant portion that has at its vertex an outlet, and associated therewith are lower and upper valve seats 7 and 8 on the casing and cap, respectively. An upwardly closing valve 9 coiiperates with the lower valve seat 7, and has a guide stem 10 passing therethrough. The valve 9 is carried by a float 11 that extends below the inlet 4: into the liquid chamber 12 formed by the portion of the casing below said inlet. An upwardly opening automatic valve 13 cooperates with the upper valve seat 8, and has an upstanding head 14 provided with a transverse channel or slot 15, this head operating in a socket 16 formed in the upper end of the cap 6 and of greater diameter than said head. A plug17, threaded into the upper portion of the socket and having an exposed knurled head 18 or any other suitable Illl2;;'\f01 operating it, has its inner end disparts in all the figures of the posed above the head 14 and is movable into and out of engagement .with said head. it is provided with a central port 19, the inner end of which registers with the slot or channel 15 when the head of the valve abuts against the inner end of the plug, and said port has a suitable exhaust 20.
The operation of the structure is substantially as follows. \Vhen the plug 18 is raised, it will be evident that the valve 13 can move upwardly from its seat 8'. Consequently air expelled from. the radiator, will passthevalve seats? and 8, and inasmuch as the valve 13 will be held by the pressure against the inner end of the plug 17, this air will find its Way through the channel 15 and .port 19, and thus escape through the exhaust 20.- When, however, liquid collects in the lower portion of the casing 3, it will cause the float 11 to rise, and
thus the valve 9 will be seated. On the other hand, if the pressure within the radiator falls belowthat of the outer air, the
From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, with 1:
out further description, and it will be unden stood that various changes In the size, shape,
proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the ad- 1 L vantages of the invention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination of a Vertically-dis posed casing having a reentrant upper end, there being an opening and a valve seat in. the bottom of the reentrant end, means forming communication between the inte rior of the casing and a container of a vaporous fluid under pressure, a float in the casing carrying a valve at its upper end for ends, said partition having apassage, the
upper end of which terminates in a seat, a
bodily movable valve supported on the par-.
tition and consisting of a stem movable freely in the passage andexpanded at its upper end into a head for engaging the seat, the head of the valvehaving' a transverse channel, and a plug threaded in the upper end of the said tubular cap directly over the valve to normally limit the opening movement thereof and adapted tobe screwed inwardly into engagement with the valve for holding the same on its seat, said plug having a duct extending therethrough with the outer end open to the atn'iosphere' and the inner end communicating with the casing, such communication being controlled by both valves independently.
2. An attachment for vent devices com-' arisin a tubular ca) havin a transverse partition intermediate its ends, said partition being provided with a passage-that terminates at one end in a valve seat, a bodily- ,movable valve adapted to engage the seat and provided with a stem freely movable in the said passage, a plug threaded 1n the cap above the valve to form a retalner therefor and movable to engage the valve for holding MICHAEL L. PARKER.
