vacuum RADIATOR VALVE Filed oct. 2S, 1927 Patented June 24, 1930 UNTED STTES PAT VACUUIYLRADIATOR VALVE Application :filed October 28, 182'?.

This invention relates to an improvement in vacuum radiator valves, and has for its object to provide a valve ot the character set forth which will be simple in construction and effective in its operation, the valve embodying therein a spherical valve member adapted to operate automatically to permit air to escape from the valve, to prevent airl from entering the valve and to prevent steam from escaping from the valve.

Another object of the invention is to provide a means for preventing the movable valve member and valve seats with which it co-operates, together with the passages leading to the valve seats, from becoming clogged with impurities, such as, particles ot rust, dirt and grease, which may be carried by the steam into the valve.

The invention consists in a valve as set zo forth in the following specification and particularly as pointed out in the claims.

Referring to the drawings:

Figure 1 represents a rear elevation of a valve embodying` my invention.

F ig. 2 is a central vertical section taken on the line 2-2 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents a casing comprising a base portion 6 and an upper' portion 7, the latter being secured in any suitable manner to said base portion within a recess 8 which extends downwardly from the top thereof, said recess being shouldered at 9, thereby forming a seat upon which the casing member 7 rests. The base 6 is, furthermore, provided with an externally threaded arm 10 having a iiuid passage 11 extending therethrough and communicating with the recess 8.

Located at the top of the casing member 7 is a nipple 12 having a passage 13 extending therethrough. A nozzle 14 is detachably secured to the portion oi' the nipple 12 which projects above the top of the casing member 7, and ports 15 provided in opposite sides of said nozzle communicate with the passage 13. The portion of the nipple 12 that is located within the interior 01' the casing 5 has a sleeve 16 attached thereto and Serial No. 229,322.

said sleeve has a valve chamber 17 provided upon the interior thereof. A valve seat 18 is formed at the lower extremity of the nipple 12, said seat being formed at the intersection of the passage v13 and lower extremity of the nipple 12, and in like manner, another valve seat 19 is formed at the lower extremity of the chamber 17 where said extremity is intersected by a passage 21. A port 22 provides communication between the passage 21 and the exterior of the sleeve 16.

Resting upon the shoulder 9 of the base member 6, above the recess S therein, is an inverted cup-shaped member 23, in the sides of which apertures 211 are provided, in order that air and steam may circulate through the valve. lhe function et the inverted cupshaped member 23 is to intercept the dirt and. other impurities that may find their way into the valve from the radiator through the passage 11. rlhe cup-shaped member 23 is prevented from lifting from shoulder 9 by a pin 25, the lower extremity of which engages the upper surface ot the member 23.

As an added protection in preventing impurities from reaching the valve mechanism, a baille plate 26 is also provided interposed between the inverted cup-shaped member 23 and said valve structure. The baille plato 26 is held in position against the lower extremity of the sleeve 16 by the pin 25 which is in turn mounted in said sleeve, being secured at the lower extremity of the passage 21 in which it has a force ht.

The general operation of the valve hereinbefore specifically described is as follows Assuming that the valve is attached in the usual well-known manner to a radiator and there is a pressure of steam within the radiator, said steam will act to force the spherical valve member 2O against the seat 18, closing the passage 13 and thereby preventing the steam from within the system from being/discharged through the ports 15 to the atmosphere.

1When there is no pressure of steam within the radiator and system, the spherical valve member 2O will fall by gravity and rest upon the valve seat 19, closing the passage 21' and preventingair from entering the radiator and system. if, on the other hand, there is air within the radiator to the extent that said air prevents the efficient circulation oit' the steam through the radiator, said air will canse the spherical valve member 2O to rise slightly from the seat 19, allowing the same to pass by the spherical valve member and upwardly from the valve through the pas sage 13 and ports 15 until such time as said air is removed from the radiator, whereupon the incoming` steam entering the radiator will again torce the valve member upwardly and close the passage 13.

The function oit the inverted cup-shaped member 23 is to intercept the impurities which enter the valve from the radiator' through the passage 11 and a large percentage of these impurities will be confined within the interior oi the cup-shaped member and recess 8. A very small percentage, however, of impurities may pass through the apertures 2% and to prevent `these impurities `from reaching the valve mechanism the baille plate 26 is provided, said plate being,` constructed and arranged to intercept such impnrities and prevent their reaching the movable valve member and its seats.

claim:

l. A vacuum radiator valve having, in combination, a casing provided with a passage adapted to communicate with a iiuid circulating` system, a nipple mounted in said casingl and provided with a port communicating with the atmosphere, a sleeve attached to said nipple and co-operating therewith to term a `{iuid chamber, a movable valve member within said fluid chamber and adapted to close said port, an inverted cup-shaped member interposed between said passage and movable valve member to intercept impurities ente ing the casiniy through the passage, means depending from said sleeve to engage said cnpeshaped member and prevent the same Jrom lifting` from above the inner extremity of said passage, and al baiiie plate attached to said sleeve and intercepting' impurities within the casing, whereby they are prevented from reaching the valve member.

2. A vacuum radiator valve having, in combination, a casing provided with a passage adapted to communicate with a Afluid circulating system, a nipple mounted in said casing and provided with a port communicatino with the atmosphere and having' a valve seat formed thereon, a sleeve attached ip seid nipple and co-operating therew' to form a fluid chamber and provided with a valve seat thereon, a spherical valve member within said fluid chamber and adapted to engage either ot said valve seats, an inverted cup-shaped member interposed between said passage and sleeve to intercept impurities entering` the casing through the my hand.
