J_ MITCHELL 2,134,881 AIR CONDITIONING DEVICE Filed May 26, 1937 ' -2 Sheets-Sheet 2 2 INVENTOR ; JESS MITCHELL BY lq TTORNE Y Patented Nov. 1, 1938 2,134,881 UNITED STATES PATENT OFFICE 2,1 34,881 AIR CONDITIONING nnvrcr. Jess Mitchell‘, St. Louis, Mo. ‘ Application May 26, 1931, Serial No. 144,784 1 Claim. (Cl. 257-202) ’ My invention has relation to improvements in ?ts snugly within the tube 4 and is of a length air conditioning apparatus‘ and consists in the so that it extends from the inner edges of the novel features‘of construction more fully set forth ducts III to an annular?ange [2 formed on the in the speci?cation and pointed out in the claim. inner end of tube 4. Member I I has a diamet The principal object of the invention is to pro rically disposed partition l3 running through it vide a compact unitary device‘for cooling or heat from end to end ‘and a semicircular end wall l4 ing ‘and circulating the air within a room so as between said partition and the periphery of said to either lower or raise the temperature of said member II. room air. ' ' The partition l3 and end wall l4 form a con 10 It is a further object of the invention to pro tainer within the member II in which ice I, or 10 vide such a device that may be manufactured at other cooling medium, may be held. A cover low cost and that may be readily moved from plate 15 is provided for said container, between _ which and a cover plate l6 for the tube 4 there These advantages, as well as others inherent 15 in the invention, will be better apparent from a is disposed a coil spring IT to take up any play detailed description thereof in connection with when the motor M and fan F are operating. When‘ the apparatus is used as an air cooler, the ice container formed within the member II is disposed at the top of the tube 4; but if it is desired to use-the apparatus as an air heater, this container-may be inverted and a suitable heating element (not shown) disposed either within it or on the partition I3, The operation of my improved air conditioning room to room as desired. the accompanying drawings, in which: w Figure 1 is'a side elevation of my improved air conditioning apparatus; Fig. 2 is an end elevation looking toward the open end from which the air discharges; Fig. 3 is a vertical transverse section . taken on the line 3-3 of Fig. 1; Fig. 4 is a vertical longitudinal section through the apparatus taken, on the line 4-4 of Fig. 2; Fig. 5 is a vertical cross’ 25 section taken on the line 5-—5 of Fig. 1; Fig. 6 is a side elevation of a fragment of the apparatus showing a ?lter applied to the air inlet duct; and Fig. 7' is a longitudinal sectional detail taken on they line '!--1 of-Flg. 6. 30 , between the parts so as to eliminate vibration 15 apparatus is as follows: We will assume that the container of the mem ber H is charged with ice ‘so that the apparatus may be used as an air circulating device. The motor M'is now started so as to rapidly rotate the Referring to the drawings, i represents a cylin— drical casing supported by feet 2, 2 on a suitable fan F, the blades of which will force air outward— 30 ly through the space S into the room and draw 'base 3 on which a motor M is also mounted. the room air through the ducts l0 into the mem concentrically disposed within the casing I there ber ll below the partition l3. As the air travels is a tube 4 of smaller diameter so as to leave an through the member II, it will, of course, be 35 annular space S between said tube 4 and the cas cooled by contact with the cool surfaces of the 35 ing l. The tube 4 stops short of a closure plate member ll through which the air is moved by 5 disposed over the end of casing I adjacent to the action of the fan F. Thus, we have a con tinuous circulation of air through the ducts Hl, ‘ motor‘M so as to provide a space S’ for a fan F securely ?xed on the motor shaft 6. The blades through the member II, and back through the 40 ‘I of the fan are ?at but have their outer edges space S within the casing I from which the cooled 40 8 and inner edges 8 arcuate so as to follow the air is discharged into the room. The cover plate 5 is removable, for which pur contour of the casing l and-tube 4, respectively. It will be observed (Figs. 1 and 4) that the inner pose I provide a radially disposed tapering open edges 9 of the blades slightly overlap the adjacent ing l8 leading from the center thereof to the 45 end of tube 4, and the blades are pitched so that , periphery of the plate 5. This opening l8 per 45 upon being rotated in the proper direction, they will force air through’ the space S toward the mits the cover plate to be disposed over the shaft ‘6 of the motor, after which a sliding gate i 9 may open end thereof. The tube 4 is supported with be slipped into the opening and held in place by guide lugs 20, III, as well understood in the art. A plurality of ‘spring clips 2|, 2| may be secured 50 adjacent to the inner end of the casing l for the _in the casing l by a plurality (four in the present instance) of ducts l0 ?ied at their inner ends in the wall of tube 4 and at their outer ends in the ‘ casing I. The side of each ‘duct toward the .fan F'is V-shaped so~ as to offer a minimum of resistance to the air that is forced through the I‘ casing by the fan F. A cylindrical member ll purpose‘ot engaging and holding in place the cover plate 5. ' Referring to Figs. 6 and '1, 22 is an air perviousv screen held in place on the end or the duct II 55 2 2,184,881 by a spring holder 23 shaped to ?t the outline of the duct l0. Having described my invention, I claim: An air conditioning apparatus comprising a cylindrical casing closed at one end, a. tube dis tube being closed and having air inlet ducts lead - ing through the casing wall, an air conditioning device removably disposed within said tube, and a fan in the space between the tube and the closed end of the casing, said fan having blade-s oper posed concentrically within the casing and spaced ating between the cylindrical walls of the casing from the walls thereof, one end of said tube be and of the tube. ing spaced from the closed end of the casing and having an air outlet and the opposite end 0! the JESSLHTCHEIL.
