HUMIDIFYING-RADIATOR.

arplicmon filed February 25, 1915. Serial so. 10,424.

In my construction each radiator unit is provlded with a humidifying chamber so dlsposed in relation to the heating conduits as to be within the lateral planes thereof, thus providing means whereby any number of such units may be assembled to form the complete radiator according to the require ments of the room, furthermore such a radiator has the same appearance as the usual radiators used in steam heating systems and 1s equally accessible for cleaning. In my preferred construction I have also provided means whereby the water chambers of the radiator may be readily exposed for the purpose of filling the water chamber or for cleaning the same.

The drawings illustrate the preferred embodiments of the invention.

Figure 1 shows a radiator embodying my invention standing on the floor of the room and connected with means outside of the room for maintaining a constant supply of water in the evaporating chambers of the radiator Fig. 2 is a vertical sectionalview of one of the radiator units of the preferred construction Fig. 3 is a horizontal sectional view on lines 3-3 Fig. 2, Fig. 4 is a vertical sectional view of a modified form of radiator construction, and Fig. 5 is a horizontal surface view on lines 5-5, Fig. 4.

The radiator as illustrated in Figs. 1 and 2 of the accompanying drawings comprises a series of units or sections 1, each section comprising parallel vertical conduits 2 for a heating fluid such as steam or hot water,

said conduits being connected at the bottom by a relatively large chamber 3 thus forming a U-shaped conduit. The several units areconnected at the bottom preferably by push nipples 5 and at the top by push nipples 6 thus providing for a constant circulation of fluid through the series of radiator sections. The heating be introduced at the bottom of the radiator through the pipe 4 in the usual manner passing thence through the conduits 2 and the push nipples 5 and 6. When hot water isv used the same may be introduced through the pipe 4 at the top of the radiator, passing thence through the push nipples 6, the conduits 2 and chamber 3, leaving through the usual discharge opening in. the manner usual-in hot water systems.

Each section is provided with a water fluid, if steam, may

chamber 2 within the loop formed by the vertical conduits 2 and the horizontal connecting chamber 3, the sides of the water chamber t being fiush with or within the lateral planes of the walls of the conduits 2. The walls of the conduits 2 and oil the water chamber 7 are desirably made integral being connected by relatively thin webs 8 of such cross section as to reduce the heat conducted from the heating conduits to the water chamber suciently to. maintain the water in the chamber at a desired vaporizing temperature below the bog point of water. in some instances especially where steam is used the heat conducting area of the webs may be, still further reduced by cutting away the webs at intervals to term slots 9 in which the air may circulate. By this means any radiator of my construction may be adapted'tor the particular room in which it is to be located so that it will supply the amount of moisture necessary to maintain the room at the desired degree of hidity.

"The water chambers of the radiator sections constructed in the manner aforesaid are connected by push nipples 10 m that all of the water chambers of each radiator are connected together and a uni-form level or water maintained throughout the entire radiator.

it is "sometimes desirable where a large number of radiators are used upon a single floor to provide means for maintaining the water in the water chambers at a constant level, such means may be easily. provided by the means illustrated in Fig; l which consists in a float tank It located in an adjacent room or closet connected by a suitable pipe 12.with an inlet pipe 13 leading to the first section of the water chamber of the radiator. This pipe may be concealed beneath the floor of the room and provided with a riser lying adjacent to the riser of the steam pipe which leads to the steam conducting sections of the radiator.-

In the preferred embodiment illustrated in Fig. 2 the heating conduits are til-shaped, the upper end of each leg of the conduit being connected through the nipple 6 of the adjacent radiator section. This leaves the upper ends of the water chambers open so that the same are accessible for cleaning by a brush or cloth. A suitable perforated cover 14 of the required width and length maybe provided to inclose the top of the radiator thus constructed.

in order to make the radiator construction more hygienic the walls of the water chamher 7 may be provided with a coating 15 of porcelain, enamel or like substance.

In Fig. 4 l have illustrated a modified form of radiator which is substantially identical in form with the usual radiator now in use. In this construction the radiator sections are composed of parallel vertical conduits 21 for heating fluid, connected at the bottom by a chamber 23 and attheir top by an arch shaped conduit 2-l. The water chamber 25 is, as disclosed in Fig. t, disposed within the lateral planes of the walls of the heating conduitsand is provided at its top with a relatively large opening 26 adapted to permit the tree evaporation of the water wit the water chamber. The lower portion or bottom of the water chamber may be made distinct from and separated from the outer wall of the chamber 23 to provide an air space 27 beneath the lower end of the water tank. The walls of the water tank and oil the conduit are preferably cast integral, the webs connecting the same being relatively thin and cut away to provide apertures or slots 28 by means of which the radiating area of the web may be sciently reduced to maintain the water at the desired temperature. lln this construction the several sections of the radiator are connected at the bottom by push nipples entering apertures 29 at the bottom and similar push nipples entering apertures 30 at the top. as in the usual radiator construction. llt is especially desirable to use means for maintaining a continuous supply of water to the water chambers of radiators of this type since the water chambers are not so easily accessible as the type disclosed in Fig. 2

and it is to be understood that such radiators may be connected to the float tank in the manner heretofore described.

With the radiator construction disclosed herein a relatively large body of water is maintained within the radiator sections and the heat transferred to the water chambers is proportional in each case to the amount of heat delivered to the room. By properly reducing the area of the webs connecting the water chambers with the walls of the steam conduits a nice adjustment may be made which. will cause approximately the desired amount of moisture to be supplied to the air at all times.

While l have described the water chamber of the radiator as being constructed preferably integral with the Walls of the conduit it is to be understood that the water chamber may be made separate from the conduit 'and assembled within the same the walls of the conduit and of the water chamber being connected by a web of suitable conducting material.

lit will be understood that the embodiment of the invention disclosed herein is illustrative merely and that it may be embodied in other forms within the spirit and scope of the following claims.

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

l. A radiator unit comprising a. conduit for a heating fluid and an open chamber adapted to contain a vaporizable fluid, the wall of said chamber being connected to the wall, of the conduit by arelatively thin web of heat conducting material apertured to reduce the conducting area of said web sufficiently tomaintain the contents of said chamber at a desired temperature below the boiling temperature'of the liquid.
