AUTOMATIC AIB-VAPORIZING DEVICE FOR RADIATOBS.

' Application filed May 17; 1926. Serial no. 109531.

My invention relates to a new and useful improvement in an automatic air vaporizing device for use on radiators andin the description the invention is illustrated as adapted for use on radiators, but it will appear evident that the mechanism embodied in the invention may also be adapted for use on hot air furnaces and such other places as it may be desired to use a vaporizing device for humiditying the atmosphere.

It is an object of the present invention to provide a mechanism of this class which will be simple in structure, economical of manufacture and highly etlicient in use.

Another object of theinvention is the provision of a device of this class in which the container will be maintained automatically filled with a predetermined amount 01 liquid.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood from a reference to the accompanying drawings which form a part of this specification and in which,

Fig. 1 is a perspective view of the invention with parts broken away showing it applied to a radiator.

Fig. 2 is a fragmentary sectional view taken on substantially line 2-2 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on substantially line 33 of Fig. 1.

Fig. 4 is a slightly enlarged fragmentary sectional view illustrating the valve operating mechanism.

The invention is shown in the drawings as applied to a radiator 7 having a dust shield 8 mounted thereon. This dust shield is provided with a cover 9 having the side flange 10. Mounted beneath the cover 9 preferably centrally thereof is a pan 11 having side walls 12 and 13 and end walls 14 and 15, the side wall 12 being provided with a plurality of notches 12'. The end wall 14 is provided with openings 16 and 17, the opening 16 communicating through the neck 18 with a cylindrical container 19, this cylindrical container communicating through the housing 20 with a cylindrical container 21 which communicates with the interior of the pan 11 through the wall 14 by means of the neck 22. Projected through the opening in the base 23 of the housing 20 is a neck 24 carried by the plug 25, this neck 24 having a bore 24 with which communicates a' pipe and being positioned at opposite sides of the base 23 to provide a water tightconnection. Threaded on the neck 24 is a cupshaped cap or valve seat-bearing member 28 and formed in its base is a valve seat 31 for engaging the end of the needle valve 32 which projects through an opening 33 formed in the bench or deflecting disc 34 which is mounted on the body ofthe cupshaped cap 28. Fixedly mounted on the needle valve 32 is a collar 35, projecting outwardly from the periphery of which are spaced discs 36 and 37. Mounted in the side walls of the housing 20 are pins 38 and 39. The pin 38 is projected through a cylindrical sleeve 40 projecting outwardly from one end of which is an arm 41 carrying an air float 42. Projecting diametrically outwardly from the sleeve 40 opposite the arm 41 is an engaging finger 42 which is adapted to engage between the flanges 36 and 37. Pivotally mounted on the pin'39 is a similar cylindrical sleeve 43 carrying the diametrically extending arm 44 upon which is mounted the air float 45. Projecting outwardly from the sleeve 43 diametrically opposite the arm 40 is an engaging finger 46 adapted to engage between the flanges 86 and 37.

As shown the float 42 is positioned in the cylindrical container 19 and the float 45 is positioned in the cylindrical container 21, suitable s'lots being formed in the side walls of these containers for the projection of the arms 41 and 44 therethrough. The construc tion is such that when the water or other liquid in the containers 19 and 21 is reduced below a certain level the floats 42 and 45 will move downwardly to rock the engaging finger 42 and 46 upwardly to engage the flange 37 thereby lifting the needle valve 32 from its seat 31 and permitting the flow of water into the housing 20, the containers 19 and 21 and into the pan 11. As the water in these containers and in this pan rises the floats 42 and 45 will be raised to the position to effect an engagement of the engaging fingers 42 and 43 with the flange 36 so as to seat the needle valve 32 on its seat 31, thus shutting oii the flow of water into these containers and into the pan 11. It is thus be lieved evident that the amount of water in the'pan 11'. is automatically controlled at all times and that the manual replenishing of the Water in this pan is dispensed with solong asthevalv-e 27 is opened to permit the flow of Water through the pipe 26.

I am aware thatliquid containers have been already used. for this purpose but it is necessary that these containers be filled manually which involves considerable labor, particularly where a large number of pans are used, suchas in large buildings, like hotels, etc. With the present device this labor is dispensed with and the presence of water in the pans 11 is assured at all times so that the proper humidity ofthe atmosphere may be maintained. When the pans are filled manually it is practically impossible to maintain the proper supply of water in the pans as thexvaporizing in the pans depends upon the amount of heat which is radiating from the radiator and this will vary in difierent rooms resulting in complete The housing 20 is provided with a cover 20 which may be removed at will to permit an inspection or an adjustment and repair of the valve controlling mechanism.

While I: have illustrated the preferred form of structure I do not Wish to limit myself to the precise form of structures shown ,2 eeaero but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

Having thus described my invention What I claim as new and desire to secure byLetters Patent is: I

1. A device of the class described co1nprising: a liquid container; float chambers mounted on and communicating with said liquid container; means for conducting liquid to said chambers; a needle valve for controlling the flow of liquid to said chambers; floats in said chambers a collar mounted on said needle valve; flanges on said collar; engaging fingers rockable by said floats for engaging said flanges and moving said needle valve from its seat and toward its seat depending upon the direction of rocking of said fingers.

2. A device of the class described comprising a liquid container; means for conducting liquid into said container: a valve seat bearing member; a needle valve for seating in the valve seat in said member, said valve seat bearing member being adjustable relatively' to said needle valve; a deflecting member carried by said valve seat bearlng member for deflecting the liquid entering into said GEORGE E. coon.
