Application .filed ma 6,

My invention belongs to that general class of devices known as heating systems and relates more particularly to a heating apparatus particularly adapted for use in large shops, assembly halls, auditoriums, gymnasiums, and the like, although the same may of course be used wherever found applicable. The invention has among its objects the production of a unit heater of the kind described that is simple, convenient, efficient, compact, light weight and comparatively inexpensive. More particularly it has as an object the production of a device of large capacity or efficiency, and yet of such weight that it may be suspended or supported from suitable supporting means above the floor without requiring heavy, bulky and cumbersome supports. It also has as an object the production of a device of the kind de scribed upon which a power driven fan may be mounted in such a manner that the power element, particularly if an electrical motor. is protected from dirt and excessive heat. In the preferred construction, the motor is air cooled. Many other objects and advantages'of the construction-herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this end, my. invention consists in the novel construction, arrangement and combination of parts hegain shown and described,-

and more particularly pointed out in the claims. 2

In the drawings, wherein characters indicate like or parts: v

Fig. 2 is a front elevation of the same;

Fig. 3 is a rear elevation, with a portion K like reference correspondmg broken away to show the construction- Fig. 4 is a sectional view taken substantially on line 4-4 of Fig. 1;

Referring to the drawings, in which the preferred embodiment of the invention is shown, 1 represents a main or pipe such as a steam pipe, which may be controlled by a valve (not shown) and may be supported by hangers 2 or any equivalent supporting means from a ceiling, wall or the like, I have 1925. Serial No. 28,369.

illustrated a standard return pipe 3, it being understood that this may be a return pipe or a vented pipe provided with the usual ail the manifold 4 is a heating unit or radiator construction 15, which I prefer to make in a form very similar to an automobile radiator the same in the particular device illustrate consisting of tubes. or pipes 16 communicating with chambers at the top and bottom and carrying fins or'thin sheet metal plates 17. The manifolds 4 and '11 communicate with the top and'bottom chambers respectively of the radiators 15, the manifolds 4 and 11 being secured to the radiators by bolts 18, or the equivalent. It will be noted that the manifolds 4 and 11 are positioned to balance each other.

Secured to aligned surfaces of the radiators 15 is a front plate 19 in an aperture of which is mounted an annulus 20. An elec tric motor 23 is suspended fromthe manifold 4 by rods 24 which are secured to 'flanges 25 formed integral. with the manifold 4. The motor 23 is provided with a shaft 26 to the outer end of which are secured a plurality of inclined vanes 27, the

vanes being disposed within the annulus 20,

' and being adapted to draw air through the radiators 15 when the motor shaft 26 is rotated in the proper direction.- The flow of air through the radiators 15 and through the annulus 20 is indicated by arrows inthe manifolds 4 and 11. Secured to the rear edge surfaces of the radiators 15 is a back plate 34 and secured to the upper edge surfaces of the radiators is a top plate 35. The chamber, which is defined by the bent plate 29, the back wall 34. and the top wall 35, is

closed at its'lower end by a wire mesh 36 and a felt pad 37. The wire mesh 36 and the felt pad 37 permit the vanes 27 to draw air past the motor 23 to cool it, such air being drawn through the aperture 31 and projected from the apparatus by the vanes 27 to mix with the heated air, flowing .from the radiators 15. The wire mesh 36 and the felt pad 37 screen dust from the air flowing to the motor 23. When the apparatus is subjected to chemical fumes, the pad 37 may be treated with suitable chemicals to remove or neutralize these fumes, thus prei'rinting injury thereby to the motor 23; However in some instances the wire mesh 36 and felt pad 37 may be dispensed with entirely.

Pivotall mounted adjacent the upper edge of t e frontv plate 19 is .a plate 39, which may be secured in a plurality of adjust'ed positions to deflect the current of air flowing from the vanes 27. The means for securing the plate 29 in these positions in the desired direction in the vertical plane which is coincident with the axis of rotation of the shaft 26. I

' When the apparatus is in operation, steam is supplied to the radiators 15 by way of the steam pipe 1, the nipples 6 and 7 and the manifold 4. The electric motor 23 is connected with any suitable source of electrical energy (not shown), whereupon the vanes 27 draw the air through the radiators 15. This air is heated by the radiators and is then \projected against the plate 39 which deflects it in the manner above described. The motor 23 is cooled by the air which is drawn-through the wire mesh 36 and the felt pad 37. It is obvious that the unions 8 and 11 permit the apparatus to be adjusted around a vertical axis so that by suitably adjusting both the apparatus as a whole and the plate 39- by'itself, the'heated air may be directed to any desired portion of a room.

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 l miting myself to the exact form, constructlon, arrangement and combination of parts herein shown and described or uses mentioned.
