Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed January 11, 1917. Serial No. 141,869.

To all whom it may concern:

Be it known that I, CLARENCE C. SHIPP, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Automatic Air- Relases and Humidifiers for Radiators, of which the followingis a specification.

This invention relates to a device for automatically exhausting .air from steam and hot water radiators, to accelerate the action of heat radiation, and also for exhausting amounts of water from time to time as may be required for humidifying purposes.

One of the objects of the invention consists in the provision of a device of the above character in which, when the radiator is out of operation, the shrinkage of the cooling water will sufliciently lower the water level within the catch-pan, with a corresponding reduction in the elevation of the float, as to cause the valve attached to said float to be unseated, thereby allowing any subsequent accumulation of air within the radiator to be discharged when the latter is again set into operation.

A further object of the invention consists in the provision of means whereby the discharge of air and water from the radiator is controlled by the amount of discharged water accumulatedin the humidifying water catch-pan.

I accomplish the, above objects of the invention, and such others as may appear from a perusal of the specification and claim, by means of the construction illustrated in the accompanying drawings, forming a part hereof, in which- Figure 1 is a view partly in section and partly in elevation of the mechanism for controlling the outflow of air and water'diSr charged from the radiator. Fig. 2 is an en'- larged detail sectional view through the end of the air and water discharge pipe. Fig. 3

is a fragmentary detail in side elevation of" a radiator showing the position and application of my invention. Fig. 4 is an end elevation of the construction shown in Fig. 3.

Referring to the drawings, 10 represents the several coils or sections comprising a conventional style of a steam and hot water radiator, in which each coil is provided with a vertically extending centrally arranged opening 11. To meet modern heating requirements which, among other things, ne-

cessitates the maintenance of a certainamount of humidity within a room, I provide means consisting of a water catching and storing pan 12 whichis open at its top to permit free escape of vapor into the room, and for convenience and to prevent marring the appearance of the radiator pan 12 is introduced into the openings 11 in the radiator coils. In order to insure constant operation of the humidifying apparatus and to accelerate the action of heat radiation, by the liberation of air from within the radiator, I introduce an automatic regulating device which not only removes the accumulated air from within the radiator but automatically maintains a sufiicient sup-ply of water in catch-pan 12 at all times for meeting the constant demands in maintaining the requisite percentage of moisture.

To accomplish the several objects heretofore noted, I establish communication with the interior of the radiator through the usual aperture 15, generally containing one of the many forms of'ai-r releasing devices, by means of an'elbow 16 which communicates with a small hollow tube 17 the latter extending downward into the catch-pan 12 where it is coiled to'form a hollow chamber 18. Examining Fig. 1, it will be noted that tube 17 is of small diameter and is formed into a series of closely arranged spiral convolutions which will yield more or less when subjected to the influence of internal air pressure, thereby allowing gradual and silent exhausting of the air discharged from the radiator into chamber 18. One of the objects in forming the convolutions in tube 17 is'that after the air has been exhausted from the radiator, the subsequent flow of vapor will be condensed to water before its discharge into valve chamber 20. As the air and water are discharged from tube 17 they pass into a valve-chamber 20 located in valve-housing 21, .and in chamber 20 avalve 22 operates to control the flow of both the air and water. Presuming valve 22 to be unseated from its valve seat 23, the water passes from valve-chamber 2O upward along to form a chamber 27 and the latter is closed at the top by means of a cap-screw 28.

lu"oe extends upwardly through chamber 18 and plug 26 and has its discharge end at the floor line of chamber 27. llhe discharge end of tube 25 is normally sealed against inward flow of air or Water into the radiator by means of a gravity seated spherical ball 30, the ball being induced to seat itself through the inclined formation or the bottom of chamber 27. Air is allowed to flow out of chamber 27 into chamber 18 through an aperture 31 in plug 26. As the air discharging into chamber 18 is more or less underpressure, the buzzing and sizzing noises usually accompanying such discharge are eliminated by the cushioning efiect of the convolutions in tube 17, the said convolutions heingsufiiciently sensitive to yield under the influence or" internal pressure, thereby causing the convolutions to spread. and allow. the air to gradually pass out from between said convolutions to the atmosphere. l Vhen sutlicient Water has accumulated in pan 12 to raise the Water level a sufficient height to elevate float 35-the latter elevates and Water level Within catch-pan 12 has been lowered to a point to no longer sustain float 35 the latter descends, causing valve 22 to be unseated and the discharge of Water into pan 12 to be reiistablished.

Having thus fully described my said in-- vention, What ll desire to secure by Letters -Patent, is

Y in combination, with a steam and hot Water radiator, a pan for receiving the Water discharged from said radiator, an air and Water conductor-means communicating With the interior of the radiator and having its discharge in advance of a controlling valve, said conductor-means being provided With a series of convolutions for condensing vapor and for providing a chamber for receiving the exhausted air from the interior of the radiator, an air'conductor-means extending from the rear or" said valve and discharging into said chamber, means for closing the discharge endof said second conductormeans against back fiovv of air, a valve for controlling the outward flow of air and Water from the radiator, and means actuated by the rise and fall of the Water Within said pan for seating and unseating said valve.

In Witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 30th day of December, A. l). one thousand nine hundredand sixteen.

CLARENCE C. Sl'lllPP. [13.8.]
