FAN SUPPORTING DEVlCE.
APPLICATION FILED SEPT-2.1919- 1,332,875, Patented Man-9, 1920.
MARK Amswoia'rn, or KANSAS oIrY, Miss'ounr.
rniv fsnrronaine DEVICE,
' To aZl whom. it may concern:
Be it known that I, MARI-r finiswon'rrr, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Fan-Supporting Device, of which the following is a specification.
This invention relates to supporting devices and more particularlyto rotary fansupporting devices.
. An object of this invention is to provide means for supporting a plurality of fans,
the fans depending from a rotary frame. and
being so disposed that 'the'reaction of the current of air from the fans .will cause the fentire supporting vframe toJrotate about a fixed support.
Another object of'this invention is to pro V vide a fan support of generally improved construction, whereby the device will besim- 'ple, durable, and inexpensive in constructlon, as well as conven ent, serv1ceable,practical and efiicient-in its. use.
, With the foregoing and other objects in view which will appear as'the description ,proceeds, the invention resides in the combination 'andarrangement of parts and in" Referring to the details 'of'construction hereinafter describedand claimed, it'being understood that changes in the precise embodiment'of theinvention hereindisclosed, may bemade within the scope of what is claimed without,
departing from the spirit of the invention.
' The invention hasbeen illustrated inits preferred embodiments in the accompanying drawings, wherein: V F'gurel is a side elevation, parts appearing in'section of thefan supporting device. Fig. 2 is a horizontal sectional viewtaken on line 2-4. of Fig. 1. I
Fig. 3 is a diagrammatic view showing the wiring circuit. A v I the drawing, there is shown a stationary support comprising a rod or stem 5, which is secured at its upper end to a plate. 6, by screwing the upper end of the rod 5 into a'threaded apertureformed in' the plate 6,.and a shoulder 7 carried by the rod 5 engages the plate 6 to hold the rod 5 against rotation with respect to the plate 6, which plate is secured to the ceiling of a room by suitable securing devices 6. A
bearing member 8 is threaded to the lower end of the stem 5, and the upper face of the bearing member 8 engages a shoulder Specification of Letters Patent.

Application filed September 2, 1919. Serial No. 321,293.
vformed adjacent: a lower-threaded terminal of thestem 5.
The bearing member 8 is, provided with a ballrace 9, which coiiperates with a complenienting ball race 10 formed on a bearing ring or annulus 11.
This bearing ring 11 is received in an axial socket 12 formed in a rotary supporting member or spider 13, and a plurality of radially extending arms 14: are formed on apertures 15 are formed at thef'outer end of each arm 14; and separate chains or flexible members 16 are secured to the outer end of each arm by passing the end link of each chain through the apertures 15.
shaped bracket 17 is. supported by each arm .14 through the instrumentality of the chain 16 which are secured at their lower ends to the bracket 17, as shown at 18. Each bracket'supports an electric fan F of conventional form, and each bracket and fan'is so Spaced.
An L- disposed with relation to the rotary supporting member 13, that the-axis of the fan shafts is positioned tangentiallywith respect to. this rotary supporting member or spider, or perpendicularly toeach arm.
' 'In order to convey the electric current to each fan, separate insulated distributing rings 19 are carried by thevertical stem 5 and each lead'of the line wires 20 contacts with oneofthe rings 19. Separate resilient fingers or brushes 21 arecarried by each arm l t'and yieldingly engage the rings 19, and
leads, or conductors 22 extend from these resilient fingers to the fans F. 1
. In use, the fans are put in operation by closing the electric circuit by means of a conventional ,switc-h'23, and the reaction of the-current of air put'inj motion by the operating fans,will cause the rotary supporting member to revolve about the stem 5 on 1 its ball bearings 10 and thereby uniformly circulatethe air-throughout the entire room or hall in which the device is employed.-
Having thus described my invention, what is claimed -is:--
l. A device ofthe'class described includ f ing a stationary supporting member, a rotary member supported by the stationary member, flexible members depending from the rotary member, electric fans supported by the flexible members, and means for transmitting an electric current from the usual-line wires to the said fans.
A device of the class described including a stationary supporting men'iber, a bearing member secured to the stationary sup porting member, aball race formed on the said bearing member, ball bearings engaging the said ball race, a rotarysupporting member having an axial socket formed therein, a bearing-ring positioned Within the said socket and engaging the ball bear-i11 radial arms extending from the rotary sup porting n'lember, opposed chains secured to the outer terminal of each arm, a bracket supported by the said chains, an electric fan secured to the said brackets and positioned tangentially with respect to the rotary sup porting member, separate distributing rings carried by the stationary supporting member, said rings'being in contact With line Wires, and movable conductorsextending from the said distributing ringsto the said" fans. 7 I
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of twov Witnesses.
