showm'the section is made in two par TUCJ part being substantially hemiephe. in shape while the lower part is in the rorin of *ardly curvedrim. In order to facilitate the mounting or the motor shown generally at 17, in the housing, the run 20 is removhhly attached to the upper section in any suitable manner, such for example, as by the use of the screw bolts 21 shown in Fig. 1. As will be observed. the housing); section 16 is also substantially hemispherical in siepe and is pended in the rim member 20. in a manner .hat will be set forth. hereinafter.
The motor 17 may be of any well known type used in fan construction and is provided with a siaft 22 which extends be yond the motor casing to present an end for the reception of the tar wl'ieel 23.
As shown. the motor suspended in the housing section 15 and has the housin tion 19 attached ll will readil Elli l he understood thet'the hous ng section 1.6 may be attached to the motor casing in suitable manner. sizcln for example, as by the use of the screws 24. i
In order to i -re the tan wheel a circulator; movement, the motor 17 is rotatahly si'zsg iended in the housing so that its shalt may he lined to the axis of rotation. ll l h a View to suspen' 11g the motorin the hens ing so that it may be rotated about an axis inclined to the axis of the shaft, a universaljoint connection is provided.
An examination of Fig. 1 will show'that the universal-joint connection includes a plate 18 provided with two depending spaced arms supported in the housing section 15 by means of screws 25. Pivotally mounted between the depending arms of the member 18 is a block 26 adapted to receive the bifurcated end of a stub shaft 27. It will be readily understood that, in order to permit the universal movement of the stub shaft, the arms of the bifurcated end of the stub shaft are pivotally connected to the block 26 so that the shaft may oscillate about an axis extending at right angles to the axis about which the block 26 may oscillate.
Since it is required that the motor 1'? he suspended from the universal-joint connection in a manner to permit rotation, a blocl: 28 is provided on the motor casing and has formed therein a bearing adapted to receive the stub shaft 27. It will be readily understood that the motor may be retained in position on the stub shaft in any one of a variety of ways and, in this particular construction, a connection is a complished h forming a circumferential groove in the shaft to receive a set screw 29, mounted in the block 26.
The rotation of the motor on the stub shaft 27 is effected by means of a train of gears actuated upon the rotation of the motor shaft 22. It will be seen in 1, that a worm 80, having one end slotted, is loosely mounted in a bearing provided in the bloclt 28 and is disposed in alinement with the shaft 22, the latter having a tongue formed on its end to project into the slot provided in the worm.
It will be apparent that the worm 30 may be retained in position in the bearing in any one of a variety of ways. in this particular embodiment of invention, in order to facilitate assemblage, the bearing is extended through the block 28 and provided, at its outer end, with. an internal thread for the reception of a cap 31., adapted to form a bearing for the end of the worm anc to hold it in engagement with the shaft 22.
As illustrated in Fig. 3, a shaft is rotatably mounted in a bearing provided in the block 28 and extends substantially at right angles to the axis of the worm 30. Connection is established between the shaft 32 and the worm 30 by means of a worm gear 33, fixed to the shaft32 and disposed in a chamber formed in the blocl: 28. The chamber in which the worm gear 33 is located is accessible from the end of the block and is closed by means of a cap 34,-.
In order to retain the axis of the shaft 22 inclined to the axis of rotation of the motor to give the fan wheel the desired circulatory movement, a brush-and-ring device is provided. i LS shown in i l, a ring 37 is disposed between a plurality of brushes 38, ans'ularly paced rbout the housis retained centrally positioned in the housing section with its axis coincident with the axis aboutwhich it 's desired to rotate the motor.
The ring 3? is carried by the housing section i i 'h attached to the motor, and
it will be r iily understood that thering may be set in any desired position relatire ient. Accordingly, the brushes 38 are housing section 15 and urged toward toe ring by means of springs d0.
will be observed that these springs held in position in the bushing and in gageinent with the brushes by plugs As shown, the plugs 41 are adapted to make threaded engagement with the bushin thereby providing a structure that is ea disass mbled for the re lacement of pa Further, the springs 40 urge the brus forward to compcnsat for wear.
The motor 17 being rotatably mounted, the conductors 19 cannot be directly c nnected to a con .mutator or collector rin carried by the motor. Consequently, in or er to supply the motor with electrical energy, collector rings l2 are disposed on the ring '37 carried by the motor and are located in alinement with the brushes 38.
Sine, it necessary to insulate the rings 12 from one another and from the motor 1 ring 3? preferably made of casing, ie some insulating material, such, for example, as hard rubber. ml e collector rings are constructed ime material capable of conducting electricity and are connected to the motor wind s.
The brushes 00, which are disposed to engage v he collector rings 42, are made from carbon or any other suitable material having wear-resisting properties. Since these brushes are resiliently mounted, the danger of destruction due to the ring being thrown slightly off center during operation, is greatly reduced.

Since the l'iousing section 16, is symmetrically dispo about the axis of rotation of the motor, the lower portion of the shaft 22 describes a path lying within the ring 20. The housing section 16, the lower portion of which is hemispherical in shape, is rotated in the ring. 20 about the axis of rotation of the motor, and the fan wheel 23 is given a circulatory movement.
Since the mechanism causing the rotation of the motor is connected to the shaft 22, the motor, by its own power, effects its iotation.
