ATTORNEYS Patented Oct. 23, 1934 1,977,835 ATTACHMENT FOR RADIATOR VALVES Salvatore D. Rose, Seattle, Wash. Application March 13, 1934, Serial No. 715,352

6 Claims.

My present invention relates to the general art of radiator heating and more particularly to an attachment for radiator valves.

In heating radiators it is necessary to provide air relief valves in order to permit the escape of cold air as the radiator heats up. When the air valve is not properly regulated steam and small quantities of Water are forced out from the air valves. The water is often times dirty from settlings in the heating system and the rising current of air mingled with the steam and moisture often disfigures the decorations of the walls adjoining the radiators and may deposit pools of dirty water on the carpet under the radiator thus further increasing the damage. There are further occasions when the valving mechanism or vent of the escape valve becomes inoperative, usually from foreign matter lodging around the float itself or obstructing the discharge vent. In such instances a tapping of the valve usually loosens the foreign material and causes it to function properly. Many attachments have been created to take care of the valve discharge and to provide means for restoring the normal operations of the valve. Those attachments however that have been inspected are either clumsy or expensive in construction or so completely mask the relief valve that it is impossible to mechanically remove any foreign material that may be securely lodged in the vent itself. This present attachment is believed to offer a solution for these difliculties as it provides means whereby the discharge from the valve can be easily collected and directed to a suitable receptacle. It permits the manual opening of the air vent itself and it further provides a convenient means for tapping the air valve in a manner that will be suificient to loosen the working parts and free them for further functioning yet the blow delivered cannot seriously injure the valve.

Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawings, wherein Figure 1 is a front elevation showing my device as applied to one type of air valve. Figure 2 is a fragmentary view partly in section with the point of side elevation revolved 90 degrees from Figure 1. Figure 3 is a cross sectional View along the lines 3-3 of Figure 2. Figure 4 is an exploded perspective view showing all the elements which go to make up my present attachment. Figure 5 is a side elevation of a radiator employing my dev1ce.

Referring to the drawings, throughout which ICE like reference characters indicate like parts, 10

designates the base or This band is arranged t parts forming my device clamp band of my'device;

0 support the different and to secure the same" in operative position with respect to theradiator C5 valve. Inasmuch as the many different sizes I have plicity of holes be drilled radiator valves are of provided that a multi as at 12 to provide an adjusting line of bolt receiving openings. A bolt 14 is provided to secure the device in itsdesired 05 position. Formed prefer ably as a part of band 10 are two outstandng lugs 16 and 17. J ourna'l'ed within suitable openings bail 18. hammer 20 and to have sides the torsion spring ranged so that one end in lugs 16 and 17 is the This is arranged to accommodate the coiled about one of the 7d 22. This spring isar- 23 rests upon band 10 while the other end is provided with a hook securing means at 24 to op in a manner to constant eratively engage bail 18 1y urge it down against the air valve much after the manner in which mouse traps are arranged. It will be apparent it is believed that by pulling the hammer 20 outwardly and upwardly as indicated in Figure 2 and then releasing the amount is applied to th same a tap of known e air valve itself. The

tension of spring 22 must be so arranged that the blow will be sufiicient to dislodge any foreign material and to loosen the float if it becomes stuck for any reason but should not be heavy 63 enough to seriously dam air valve itself.

Adjustably secured in p 26 which is adapted to 14 is an overflow tube 2 age the housing of the osition by means of yoke adjustably engage bolt 8. This tube might be made of any suitable material altho an annealed copper tubing plated or o therwise finished as desired is probably the most satisfactory. Secured to the upper end of tube lecting member 30. T111 28 is the shield or 001- s is formed as a coned cup and disposed with the open end directly over the air valve vent 32 in such a manner that any water or vapor discharged by the valve will be discharged on the inside of cup 30. Secured to the lower lip of cup 30 is an inwardly disposed 166 annular flange 34. Tube 28 is connected at the junction between cup 30 the showing of Figure 2.

and the flange 34 after With this arrangement it is believed apparent that anyliquid projected upwardly or steam which is condensed will be caught by rim 34 and directed to tube 28. For normal use a drip can 36 is provided. This is formed with an open top margin 38. Tube 28 is wardly faced hook memb surrounded by a lipped provided with an uper 40 which coacts with Iii) lip 38 to support the overflow or drip can 36. Now, if, as sometimes happens, the radiator contains possibly a bucket or two of water such as would far exceed the capacity of can 36, the lower end of tube 28 with can 36 removed can be bent outwardly away from the radiator sufiicient- 1y that discharge can be directed into a suitable receptacle.

The foregoing description and the accompanying drawings are believed to clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that such changes in the invention may be made in as are fairly within the scope and spirit of the following claims: I

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

1. In an attachment'for air-vent valves of radiators, the combination with an adjustable clamp and a drain tube mounted in said clamp, of an inverted cup mounted on said tube and located above the air-vent valve, and an interior rim at the lower mouth-end of the cup forming a collecting trough communicating with said tube.

2. In an attachment for vent-valves of radiators, the combination with aclamp and means for securing said clamp to a vent-valve, of a drain tube mounted in the clamp, a drip receptacle and detachable means for supporting said receptacle at the lower end of the tube,:an inverted cup mounted at the upper end of the tube, and said cup having a drain trough at its mouthend communicating with said tube.

3. In an attachment for a vent-valve for a radiator, the combination with an adjustable band and means for securing said band on the ventvalve, of a flexible tube and means co-acting with said securing means for rigidly supporting said tube in said band, an inverted cup mounted at the upper end of the tube, and said cup having a drain trough at its mouth-end communicating with said tube.

4. In an attachment for a vent-valve of a radiator, the combination with an adjustable clamp and means for securing said clamp to the ventvalve, of a drain tube rigidly mounted in said clamp, an inverted cup mounted on said tube above the vent-valve, a drain trough within the mouth-end of said cup communicating with said tube, and means mounted on said clamp for imparting vibration to the casing of the vent-valve whereby the valve may be freed from clogging.

5. In an attachment for a vent-valve for a radiator, the combination with an adjusting clamping band and its retaining bolt, of a slotted U- shaped yoke mounted on the bolt, a flexible draintube rigidly supported in said yoke, an inverted cup mounted on the upper end of the tube above the vent-valve, and an interior rim on the cup forming a drain trough in its mouth in communication with said'tube.

6. The combination with a vent-valve, a clamp ring, and means for rigidly securing said ring to the valve, of a pair of spaced journal-bearing lugs rigid with said ring, a bail pivoted in said lugs and a spring on said bail urging its free end toward the valve, and a tap-hammer mounted on the free end of the bail, for the purpose described.
