` Patented Aug. 4, 1908.
To all whom it may' concern:
Be it known that I, 4ROBERT L. DARTER, a citizenof the United States, residing at Murphysboro, in the county of Jackson and State of Illinois, have invented a new and useful lImrovement in a steamfFan, of which 'the fol owing is a specification.
This invention relates to a novel construci tionof fan adapted -to be driven lby Ibelting from any engine and especially adapted for use in shops, factories and other places where steam power is available `and fans are desired. It 1s of course obvious, however,
,that a fan c onstructedin accordance with my invention may `be driven by any suitable means other than steam power.
The invention consists in a depending stationary shaft, a disk carried by said shaft, a.
revolving casing, and fans carried by said casing and rotated independent of rotation of thecasing by frictional contact betweenl rollers carried by. the fan shafts, andthe Y of the fixed shaft.
In the drawings I have shown a' sectional view of my invention in which A represents a ceiling socket in which is rotatably held a cylindrical casing B flanged at its' upper end and held in place inthe socket by a collar C. Anti-friction balls B are larranged between the flange of the casing Aand the collar.l
A pulley D is fixed'upon the casing and Aprojecting outwardly from; the casing and below the pulley, are fan sockets E, in which are held fan blades l?.` The lower end oi the casing is flared outwardly forming an opened conical frame B2. In this portion of the casing are journaled downwardly inclined shafts G lwhich at their lower and outer end carry fan blades H, and at their inner ends are ro- -vided with friction rollers K. A fixed s aft I extends through the casing B and within the conical portion lof the casing carries a beveled disk J engaged by the rollers K. When the pulley D is driven by a suitable belt or in any other manner, the casing B is rotated about the shaftrI, im artingrotation A to thefan blades F. The b ades vI-I are also carried about the shaft I with rotation of the casing B and are at the same time rotated upon their own axis by engagement of the roller K with the disk J.
f What I claim is 1. A device of the kind described comprising a ceiling socket, a rotatable casing carried by and depending from'said socket, the lower end of said casing flaring out and forming an Aopened cone, a shaft journaled4 Within the casing a disk upon said shaft, said disk being arranged within the cone, fan-'shafts jour-
