HEATING DEVICE 'Patented Nov. l, 1932 ARTHUR IB. MODINE, OF RACINE, WISCONSIN, ASSIGNOB TO MODINE MANUFACTURING COMPANY, OF RACINE, WISCONSIN, CORPORATION OF WISCONSIN HEATING DEVICE Application filed December 24, 1928. Serial No. 328,078.

My invention relates to heating devicesand more particularly to devices comprising a radiator unit, connected with a steam feed line wherein the steam before admission to the radiator unit, is utilized to actuate a turbine which drives a fan so positioned as to force ya column of air between the radiator tubes and thereby accelerate radiation.

Another object is vthe provision of improved means for draining off the water resulting from condensation of the steam in y the turbine casing,

the water being discharged into the outlet end of the radiator unit without the possibility of any back flow or'return of steam in the direction of the main feed.pipe.

Still ,another object is the provision of'a device that is simple, compact, eifcient and satisfactory.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is aplan view of one embodiment of my invention;

2 is an elevational view of the same;

1g.3isaview along the line 3 3 of Fig.2; F Fig. 4 is a view along the line 4 4 of ig. 5 is a view along the line 5 5 of Fig. 1; and

Fig. 6 is a view along the line 6 6 of Fig. 1.

Referring now to the drawings, the numeral 10 generally designates a radiator unit 11 and 12. The radiator unit 10 is positioned horizontally and comprises a plurality of tubes 13 separated by a plurality of transversely extending fins or plates 14. The radiator unit 10 is shown as suspended from a steam supply pipe 17 which isconnected with a generally circular-shaped member 20 by means of a nipple 19 and a union 18. The nipple 19 has a threaded connection with an elongated casing 21 which forms an inlet chamber 15 into which steam is discharged from the supply line 17 through the nipple 19. l

An irregular annular-shaped casing 22 is positioned immediately underneath the member 2() and is fastened thereto by a plurality of bolts 32. A turbine wheel 23 is shown as mounted in the casing 22, upon a vertical shaft 25. rlhe chamber 15 is connected with the turbine casing 22 by a duct 27 in which a nozzle 28 is mounted. The nozzle 28 is so positioned as to discharge the steam from the chamber as a jet which impinges against the vanes of the turbine wheel 23. The resulting rotation of the Wheel 2 3 and the shaft 25, actuates a fan 24 which is mounted on the lower end of the shaft. f.

he steam, after performing work Aupon the turbine wheel 23, leaves the casing 22 and enters a conduit 35 from the lower end of which it is discharged into the header tank 11. From the header tank 1l the steam is distributed through the tubes 13 in which it loses its heat to the air currents which are set in motion by the fan 24 and enters the header tank 12 from which the steam is discharged through a return pipe 33. It is the device, performs the dual function of doing Work by actuating the turbine wheel 23 and the fan 24 which is connected therewith, and of discharging its energy in theform of radiated heat given off by the radiator tubes 13 The vertical shaft 25 is enclosed in a housing 26 whichis positioned in the path of the air currents induced by the rotation of the fan 24. v

The nozzle 28 is adjustably mounted in the duct 27 by means of a set screw 29 as is best shown in the sectional view indicated at Fig. 6. A threaded plug 30 provides means for access to the nozzle 28. for adjustment or cleaning of the same. If necessary, the entire housing48,in which the duct 27 is located can be removed by loosening the bolts 40 which are used for fastening the housing 48 to the plate member 20.

Such of the steam as is condensed in the chamber collects at the bottom of the conduit 36. A shoulder 41 prevents any of this condensed steam from flowing into the turbine Wheel 23 through the duct 27. A float valve generally designated 34 is suitably positioned in the bottom of the conduit 36 to permit the discharge of surplus Water from the conduit 36 into the header tank 12. A Water seal is also provided which prevents any possibility of back flow of steam from the header tank 12. The oat valve preferably vtakes the form of a vertical cylinder 49 having end pin bearings 42. A plug 46 provides a means of access to the oat valve 34. A hollow inverted L-shaped niember 43, mounted in the bottom of the conduit 36 provides an outlet for the surplus water and also functions to retain sufficient Water in the conduit 36 to form a Water seal. A port 44 in the plug 46 and a similar port 45 in the L-shaped member 43 provide mountings for the pin bearings 42. As thewater level in the conduit 36 rises the cylinder 49 is elevated and thereby permits Water to How 'through the port 45 and into and through the member 43 from Which'it is discharged into the header tank 12. As the Water recedes the cylinder 49 drops and closes the port 45. The port is vertical with its lower end submerged in the Water which surrounds the downwardly'projecting free end of the member 43. The Water thus retained in the conduit 36 provides a Water seal preventing any back flow of steam from the header tank 12, through the member 43.

The radiator unit 10 is fastened to the conduits 35 and 36 by the bolts 37 and 38, respeetively. The conduit 35 is fastened to the member 20 by bolts 39 and the conduit 36 is similarly fastened by bolts 40. The various members comprising the device being bolted together are easily assembled and disassembled and can be readily mounted in any suitable steam line.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the "spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangementand combination of parts herein shown and described, or uses mentioned.
