columnof air therethrough.'l

A particular object of the invention is to provide devices ofthe kind described having improved means for directing a column of air. c

One form of the invention is embodied in aV heat exchange unit adjustably suspended from a steam pipeor the like, the device preferably comprising `a radiator score through which air is advanced by a.v fan driven by an electric motor. Positioned upon one side of the radiator core are a plurality of vanes byn means of which the direction in which the air is advanced is controlled.v Many other objects and advantagesof the construction herein shown and described will be obvious to those skilled in lthe art from the disclosure herein given. v

To this end my invention consists in the novel construction, arrangement 'and combination/ of parts herein shown and -departicularly pointed out in In the drawing, wherein like reference characters indicate like or corresponding parts:

vFig. 1 is a front elevation of a heat exchange unit embodying the invention; Fig. 2 is a side elevation of the improved heat exchange unit; and j Fig. 3 is a section taken on line 3-3 of Fig. 1.

Referring to the drawing wherein I. have shown a preferred embodiment of the invention, the improved heat exchange unit `is' designated generally by the reference character 10 and preferably comprises a housing 11 formed fromupper and lower manifold members l2 and 13, respectively. It will be noted that the

manifold members

12 and 13 are substantially rectangular and that they are connected to each otherv by side plates 14 so that they forma substantially box-like chamber together with theside plates. Formed in the

manifold members

12 and 13 are U-shaped passages 15 and projecting into the

manifold members

12 and 13 are nipples 1926. -Serial No.- 112,380.

17 and 18, respectively, which communicate with .the U-shaped passages 15. The nipple 17 is operatively connected to a steam pipe 21 by means comprisinga pipe union 22, a nipple 23 and -a T fitting 24.` The pipe nipple 18 is operatively connected to a drain or return pipe 26 by-a pipe union 27, a nipple 28 and an elbow 29. A The

pipe nipples

17 and 18 are coaxially disposed so that the heating unit 10 may be angularly adjusted.

Mounted upon the manifold member 13 is a bracket 3() which supports an electric motor A31 adapted to drive a fan 32. Positioned in i front of the fan 32 and securedto the

manifold members

12 and 13 by bolts 33 is a radiator core 34 comprising upper and

lower tanks

35 and 36, respectively, which commun-icate with the U-shaped passages 15.

The

tanks

35 and 36 communicate with each.

other through tubes 38 which are preferably formed from relatively thin sheet metal.` It' will be noted that the tubes 38 areprovided with a plurality of fins 39 which are also preferably formed from relatively thin sheet metal.

Projecting forwardly from the radiator core 34 are a plurality of side plates 42 and 43 to which a plurality of substantially U-shaped .vanes v44 are pivotally 'mounted by means preferably comprising rivets 46 or the equivalent. It will' be noted that the lowermost vane 44 is pivotally connected to the side plate 43 by a pin 48 which isrigidly secured to the vane and has a lever 49 rigidly secured to it at its outer end. Pivotally securedto the vanes 46 are links 50 which are disposed between the vanes and side plates 42 and 43,

the construction being such that if the lowermost vane 44 is angularly. displaced around its pivotal axis the other vanes 44 are similarly displaced. Depending from the'lever49 are rods or cables 52 and 53 which are preferably provided with suitable rings or handles 55 at their lower ends. Obviously, the rods or 'cables 52 and 53 may be manipulated to adjust the vanes 44 so that the air `advanced through the radiator core. 34 by the fan32 may be given any desired angle with respect to the horizontal.

The operati@ of the 'ahora described. ap-

paratus is substantially as follows: Steam or hot water is supplied to the heat exchange unit 11 by the pipe 2l,.the unit being drained by the pipe' 26. The electric motor is connected to any suitable source (not shown) of electrical energy and advances a column of air through the radiator core, which air is heated by the fluid in the tubes 38. The heat exchange unit 11 may be angularly adjusted around the coincidentaxes of the nipples 17 and 18 'so that the'fan will advance the column of air in any desired radial direction with respect to the axes ot' the nipples. The vanes 44 may lthen be adjusted to direct the air with respect to the horizontal.

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 wishl to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
