G. OLSON ELECTRIC FAN.
APPLICATION FILED JULY 29.1916.
Patented Oct. 23, 1917f UNITED STATES PATENT OFFICE.
. G'U'STAF OLSON, OF CHICAGO, ILLINOIS, ASSIGNOR OF OTTE-HALF TO WILLARD M.
. MCEWEN, OF CHICAGO, ILLINOIS.
ELECTRIC FANZ.
To all whom it may concern:
Be it known that I, GUSTAF OLsoN, a citizen of the United States of. America, and a resident of Chicago, county of Cook, and
' State of Illinois, have inventedcertain new berg and Olson Patent #1,125,684, granted January 19, 1915, and to provide a mounting of this kind which afiords a superior means of tiltably supporting the fan and which is capable of being more conveniently and economically made than the means heretofore used in this type of fan.
' An illustrative embodiment of this invention is shown in the accompanying, drawings, in which- Figure 1.is a rear elevation of an electric fan, the mounting of which is constructed in accordance with this invention.
Fig. 2 is a side elevation of the same.
Fig. 3 is a detail view of the member which tiltably and rotatably supports the blower mechanism. v
Fig. 4 is-a top plan of the same.
In the construction shown in the drawings, the blower mechanism 5, which comprises the usual motor 6 journaled m a casing 7 and carrying a blade 8 on the shaft 9 thereof, is tiltably supported on a shaftor.
The relative rotation of the sleeve '13 and the member 10 is effected by a gear rack 17 formed on the periphery of the flange 14 and a pinion 1 8 meshing therewith. The pinion 18 is carried on a shaft 19 journaled 1n the'motor casing 7 and by suitable gearing, shown in dotted outline in Fig. 2, connects with the shaft 9 of the motor 6.
The shaft or member 10 has a pair of Specification of Letters Patent.
Patented Oct. 23, 1917.
I Application filed my 29, 1916. Serial No. 112,090.
As shown in the drawings, all means for controlling the relativerotation of the shaft 10 and sleeve 13 has been omitted, this fan employing the same principle of operation as that set forth in a patent of Willard M. McEwen, No. 1,214,198,'issued January 30, 1917, wherein by tilting the blower mechanism up and down in a vertical plane, through the relative rotation of the member or sleeve 13 and shaft 10, gyratory forces are brought into action which cause the fan to swin back and forth in a horizontal plane. he ratory forces cause a reversal of the directlon of the horizontal swinging movement whenever the vertical tiltin movement is reversed, and the rapidity and angular extent of the horizontal movement depends upon the rapidity of the vertical movement.
Although but one specific embodiment of this invention hasbeen herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of, this invention as defined by the following claims.
"I claim: I
1. In an air circulating device the combination of a support, a member journaled thereon, arms on said member extending outwardly therefrom and having their ends doubled back at the sides of said support,
blower mechanism, lugs on said blower mechmember extending outwardly beyond the periphery of said flange and having the ends thereof doubled back at the sides of said flange,;blower mechanism, lugs on said blower mechanism pivotally connected to said arm ends, and means on said blower mechanism coacting with said flange so as to tilt said blower mechanism in a plane transverse to the axis of the pivotal connection of said lugs and arms.
3. In an air circulating device the com bination of a support, an outwardly disposed annular flange of wave-like form mounted on said support, a member rotatably mounted on said support concentrically of said flange, arms on said member extending outwardly beyond the periphery of said flange and having the ends thereof doubled back at the sides of said flange, blower mechanism, lugs on said blower mechanism pivotally connected to said arm ends on an axis intermediate the crowns and depressions of said wavelike flange, and means on said blower mechanism coacting with said flange soas to tilt said'blower mechanism in a plane transverse to the axis of the pivotal connection of said lugs and arms. I
4. In an air circulating device the combination of a support, a member rotatably mounted thereon. and having an annular track of wavelike form, a shaft journaled on said support concentrically within said member, arms on said shaft extending outwardly beyond said track and having the ends thereof doubled back at the sides of said track, blower mechanism, lugs on said blower mechanism pivotally connected to said arm ends on an axis intermediate the crowns and depressions of said track, and means on said blower mechanism coacting with said track for causing the rotation of said member so as to tilt said blower mechanism in a plane transverse to the axis of the pivotal connection of said lugs and arms.
Signed at Chicago this 22d day of July 1916.
GUSTAF OLSON.
