Application April 7, 1937, Serial No. 135,553 2 Claims. My invention relates to the circulation of air and includes among its objects and advantages the provision of an improved fan. In the accompanying drawing: Fig. 1 is an elevational view showing the fan suspended from the ceiling; Fig. 2 is an end view of the fan illustrated in Fig. 1; Fig. 3 is a sectional view along the line 3-3 of 10 Fig. 2; Fig. 4 is a sectional View along the line 4-4 of Fig. 3; Fig. 5 is a sectional View along the line 5-5 of Fig. 3; Fig. 6 is a bottom plan view of the motor illus trating the oscillating linkage; and (0l. 230-259) of the shaft 30 will impart rotary motion to the ring 44, to the flange 58 of which I connect the blades 60. To the ring 36 I connect a lug 62. A link 64 is pivotally connected at 66 with the lug 62 and lies against a web 68 cast as an integral part of the cap 22. A slot 10 is formed in the link 64, and the web 68 carries a wing nut 12 arranged to clamp- the link against the web. 'I‘he cap 22 may be provided with an opening 14 through 10 which one end of the link 64 passes. 'I‘he axis of the bar 54 is positioned at right angles to the axes of the screws 38 so that the fan unit I8 may be tilted to different angles with respect to- the motor shaft 30 about the axes of the screws 38. 15 By tightening the nut 12, the link 64 may be clamped in ñxed relation with the web» 68 to sup port the fan unit I8 in various angular adjust Fig. 4. In the embodiment selected to illustrate my ments. The slot 52 is of such length as to ac commodate angular adjustment of the bar 54. 2 O invention I make use of an electric motor I0 which may be suspended from the ceiling I2 by. Fig. 1 illustrates one of the fan units I8 as being a hanger I4 anchored to the ceiling by bolts I6. shifted to an angular position. The hanger I4 is of tubular construction to ac A fan unit I8 is connected with each end of the commodate the wires 16 for the motor I0, and the motor I0, which units are identical in construc tion so that the description of one will cover lower end of the hanger carries a ring 18 which 25 encircles the motor I0 and is pivotally connected both. The only difference resides in the angu larity of the blades of the fans whereby the air therewith through the medium of a bolt 80 pass ing through an opening .82 in the ring 18 and is propelled in opposite directions. Fig. 3 illustrates one end of the motor I0 in threaded into the boss 84 formed on the motor. Shaft 30 carries a worm 86 arranged in mesh 30 which the ñeld frame 20 includes an end cap 22 which has interñtting relation with the frame at with a worm gear 88 flXedly connected with a 24. Bolts 26 connect the cap with the frame. shaft 90 rotatably mounted in a bearing 92 .cast The armature 28 includes a power shaft 30 at integrally with one of the caps 22. To the lower each end, and the shafts are rotatably supported end of the shaft 90 I ñxedly connect a plate 94 within bearings 32 carried by they cap 22. The which, in turn, is pivotally connected at 96 with 35 a link 88 having its opposite end pivotally con fan units I8 are connected with the shafts 30. Referring again to Fig. 3, the bearing 32 ter-_ nected at |00 with a. short arm |82 lixedly con minates in a yoke 34 which vsupports a ring 36 nected with the ring 18. It will thus be seen that L-shaped in cross section. Screws 38 have rotary motion of the shaft 30 imparts oscillatory 40 threaded relation with the yoke 34 and include movement to the motor I0. The ring 18 is of 40 shafts 40 rotatably mounted in openings in the suiìicient diameter to accommodate oscillatory movement of the motor. flanges 42 of the ring 36. The screws 38 are ar A wire guard |04 may enclose each of the fan ranged in axial alignment with their axes cor responding to the axis of the ring 36. Within the units I8. In Figs. 2 and 7, I illustrate the ring 36 as being provided with arms I06 attached to 45 ring 36 I mount a ring 44. A roller bearing as sembly 46 is mounted between the flange 48 of the ring 36 by screws |08 for supporting the wire the ring 44 and the flange 42 of the ring 36. The guard |04. The fan blades 60 are riveted to» the bearing assembly is pressed onto the flange 48 flange 58 of the ring 44 at IIO. The invention embodies two fan units in com while set screws 50 having threaded relation with bination with a single motor, which fan units 50 50 the iiange 42 secure the bearing assembly in the propel air in opposite directions. The fan units position illustrated. The shaft 30 has a slot 52 extending inwardly are directly connected with the motor shaft, and of its end within which slot I position a bar 54 , the connections are so constructed and arranged which has its ends anchored in the openings 56 as to permit adjustment with the fan units to 55 in the ñange 48. Because of the bar 54, rotation different angles. Disconnection of the link 98 55 Fig. '7 is a sectional View along the line 1-1 of 2 2,112,766 converts the rotary fan to one oi’ the stationary type. Without further elaboration, the foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapty the same for use under various conditions of service. I claim: 1. 'I‘he combination of a motor including a power shaft, a support, a fan rotatably mounted 10 on said support and arranged forpivotal move power shaft, and means for pivoting the fan about said axis and securing the same in differ ent positions. 2. The combination of a motor including a power shaft, a support, a fan rotatably mounted on said support, said fan being movably connect ed with the support for pivotal movement about an axis transversely of the power shaft, said power shaft having a slot, a bar connected with the fan at right angles to said axis and lying 10 ment about an axis at right angles to the power shaft, a bar connected with the fan and opera within said slot, and means for securing? the fan tively connected with the power shaft to rotate said` axis. the fan, said bar being movably related to the in different angular positions when pivoted about WALTER FELTNER.
