I I l 15 Z01 y FREDERICK H. SAUER, OF NEW YORK, N. Y.
AIR-VALVE Specification of Letters Patent.
Patented July 13, 1909.
Application filed March 12, 1909. Serial No. 483,085.
To all whom it may concern:
Be it known that I FREDERICK H. Sauna, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Air- Valves, of which the following is a specification.
The invention relates to improvements in air valves, and has particular reference to that class of air valves utilized in connection with systems of steam radiation.
The object of the invention is to provide means associated with the operative parts of the device, for draining water of condensation from the interior recesses of the valve structure by capillary attraction.
In the following is described in connection with the accompanying drawings, one embodiment of the invention, the features thereof, being more particularly pointed out hereinafter, in the claims.
In the drawing, Figure 1 is a vertical sectional view of a radiator-column, illustrating in connection therewith, the manner in which the valve is mounted thereon; Fig. 2 is a side elevation of parts being shown in a longitudinal section of the valve draining means; and Fig. 3 is a detailed front elevation of the valve draining means.
Similar numerals of reference indicate similar parts throughout the several views.
In the drawing, 1 indicates the conventional outline of a single or series of radiator cohunns, having suitably formed therein, a bore 2, adapted to receive threaded nipple 3 formed on the body or base casting 4 of valve 5. Said body 4 has formed thereon, a threaded shoulder 6 and has mounted therein, casing 7 inclosing the operative parts of the valve. Said casing 7 has formed on its upper end a threaded opening 8 adapted to receive adjusting screw 9 which has formed therein an air duct 10, said air duct 10 comprising the means of forming a passage or means of communication w1th atmosphere, and the interior recesses of'said valve 5. The upper exterior end of said casing 7 is threaded as at 11, and receives at that point, cap 12, provided with a vent hole 13, connecting direct with air duct 10. Said base casting 1 has centrally formed therewith a shoulder 14, having also formed therewitha lug 15, the object of said lug 15 being hereinafter described. 16 indicates a stem of any suitable material such as vulcanitc, hardened rubber or other material, having the qualities of expansibility and has suitably cut therein a central longitudinal bore 17, the lower end of which rests on shoulder 11 and surrounds lug 15; the upper end of said stem 10 is formed in any suitable shape and has mounted thereon an inverted float 18 having mounted therein at its upper end as at 19 a depending conical sha ed pin 20 and on its extreme upper sur ace an appending pin or lug 21, provided with a needle valve surface 22, adapted to seat itself within valve seat 23 in air duct 10, when the parts of said valve have expanded a pro-determined distance to close the assage from the atmosphere to the interior recesses of said valve. Said nipple 3 or inlet and outlet connection may be of any suitable length and may project within the column of theradiator, any suitable distance and is provided with an internal bore 2 1 having mounted therein a draining stem 25, said stem 25 comprises a horizontal bar having formed therewith, an enlarged lug 26 provided with an air port or passageway 27, running horizontally through the core of said lug, and then extending upwardly in draining stem head 28, communicating with the interior recesses 29 of valve Said draining stem 25 as above described comprises a horizontally extending rod 30, having its outer end bent downwardly as at 31, and has formed on its extreme lower end a drip point 32. Said horizontal body 30 has cut therein a slot 33, communicating with groove 31 which extends along both sides of said horizontal body to a point below the center of the bend atuthe outer end of said depending body. The body of said horizontal stem and lug 26 is of a smaller diameter than the interior bore 24 of nipple 3 forming on both sides of said draining stem, fluid passageways 35, communicating with the interior recesses of the radiator columns 1 and also the interior recesses of valve 5.
The operation of the device is as follows: The exhausting from the valve of the water of condensation is on the principle of capillary attraction, as when the valve head is open to the atmosphere and when the fluids enter the valve body from the radiator, said stem 25 will start to sweat or moisture will accumulate thereon and act as a means of collecting and draining of water of condensation from said valve, thus rendering the operative parts of said valve inapt to become chocked or sealed. Drip stem 25 as shown and described provides separate and independent passageways for the fluids entiering from the means of radiation and atmospherc and the draining of said valve.
What I claim and desire to secure ters latent of the United States is:
1. An automatic air valve for 'adiators comprising. a casin, a base for said casing, radiating means, said casing having a passage in the lower portion thereof forming communication with said radiating means,
by Letsaid casing also having a vent port therein,
ed in said casing adapted to control said valve, an expansion column adapted to move radially and laterally in said float and to control said valve, and a draining stein free to move radially and laterally in said passage provided with an independent air port formed in the upper body portion thereof, the lower body portion of said stem being slotted and grooved to assist the draining of said valve of the water of condensation by capillary attraction.
52-. An automatic air valve for radiators comprising a casing, a base for said casing, radiating means, said casing having a passage in the lower portion thereof forming communication with said radiating means,
said casing also having a vent porttherein, a valve controlling said port, a float mounted in said casing adapted to control said valve, an expansion column adapted to move 'adially and laterally in said float and to control said valve, and a draining stem free to move radially and laterally in said passage provided with an independent air port cut horizontally and vertically in the upper body portion thereof, the lower body portion of said stem being slotted and grooved to assist the draining of said Valve of the water of condensation by capillary attraction.
3. A device of the character described including a draining stem for automatic air valves comprising a longitudinally extending arm bent downwardly at its outer end and having formed in the upper portion thereof an independent air port, thc'lovcer body portion of said stem being slotted and grooved for the purpose set torth.
In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
