The object of the invention isfto provide an improved fan of this character inwhich the"fan"bla'de may beadjusted vertically and I secured in adj ust-able position.
"Another obj ect -is to provide" an improved". if.) fairrof this'ch'aracter ofisimple and-durable. construction, reliable in operation and easy.
and inexpensive tomanufactura I Other objects and advantages of the in vention reside in certain novel 1 features of construction; combination and arrangement of;- ).arts-which1 (will be hereinafter morev fully describedandparticularly pointed out in' theyappended "claims, reference, beiingi had to the accompanying drawings forming ,part thereof;eand'inuwhich 1, L 1 s Figure 1 is an elevational view of a fan embodying my invention, the fan blades being shown in dotted lines in adjusted position;
Figure 2 is a plan view of the adjustable connection;
Figure 3 is an end view thereof; and
Figure 1- is a side view. I
Referring to the drawings, the fan casing 5 is hung from the ceiling in any suitable manner, the motor 6 being carried by the lower end thereof. The motor includes a rotor 7 taking the form of a short cylinder which revolves the fan blades 8.
The means for connecting the fan blades to the rotor comprises an adjustable connection embodying my invention. This means includes a motor bracket, indicatedgeneral- 1y at 9, and which is carried by the rotorof the motor and a fan bracket, indicated generally at 10, which cooperates with the motor bracket and which itself is carried by the inner or adjacent end of the fan blade.
The motor bracket 9 includes base 1 1 hav: ing its inner face concaved and of arcuate form to conform to and snugly fit against the periphery of the rotor of the motor the base being directly secured to the rotor by fastening means 12. A pair of circular spaced ears 13 extend outwardly from the base and are preferably formed integral therewith. These spaced ears are each provided with a pivot bearing 14 formed centrally of the ear, the pivot bearing of one ear being alined with the pivot bearing of the other. Adjacent their outer periphery the ears are provided with alined apertures 15' one: ofwliich iszthreade'd as. shown in Figure I I I Theblade bracket comprises a 1 plate :16 provided "withv apertures-17: to facilitate ithe; attachment of the pla te to the inner end tofthe fan bladezi A circular ear'18 is integral- 'ly formed; with the inner endeofithe plate 1.6. Thecircula-r ear'is provided with acen tral pivotbearing;19 and wi'th. a-circular. series=ofapertures 20.- V

XVhenuthese: pivotybearings'; are a-linedi aiipivotwpin ori pintlev 21; is inserted, toe Xtendthrough all The ear 18 of the blade bracket ist-adapted oif-the pii' otbearings as-zshown inthedrawe ings. r This vpin-tle has wits-r; outer extremity th e ded togengage;correspondingthreads of the adjacent ear 13, as indicated at 22 in Figure 2. lVhenthe blade bracket and the motor bracket are thus assembled the openings of the circular series 20 of the ear 18 of the blade bracket may be brought into register with the openings 15 of the spaced ears of the motor bracket. l/Vhen one of the openings of the circular series is thus brought into register the lock pin 24 is inserted and secured in position by means of the engagement of the threads formed at the outer extremity of the shank with the threads formed in the aperture of the adj acent ear 13, as indicated at 26 in Figure 2, Both the head of the lock pin and the head of the pivot pin or pintle are provided with a slot 27 for, the reception of a suitable tool.
vIn practice, it will be seen that when the motor bracket and the fan bracket are assembled with the pivot pin or pintle in position and the fan blade is secured in position on the plate of the fan bracket; the
fan blade may be adjusted to any one of a plurality of positions simply by rotating it until the desired one of the circular series of apertures 20 is registered with the apertures 15 and inserting the lock pin 24 and threading the sameon. This construction and arrangement'provides for the ready and easy adjustment of the fan blades and does not require for its installation any modification of the fan blade or of the motor.
I claim 1. In a fan of the character described, in
combination, amotor having a rotor, a fan blade, and means independent-ofthe motor and of the fan blade for adjustably connecting the fan blade to the motor comprising a motor bracket including a base directly secured to the rotor of the motor, spaced ears formed on said base and provided with centrally disposed and alined pivot bearings 1 bearings of said ears, and a lock pin operatively arranged in the registering openings or said ears.
2. In a deviceof the character described for use with fans having a tan blade and a motor lncluding a cylindrical rotor, inde' pendent means for ad ustably conecting the fan blade to the motor comprising a motor bracket including a'base having a concaved arcuate face adapted to be snugly fitted against the periphery of the rotor and to be directly secured thereto, and a fan bracket adjustably connected to the motor bracket and including a fiat plate upon Which the adjacent end of the fan blade is adapted tobe seated and to be directly secured.
3. In a device of the character described for use with fans having a fan blade and a motor including a rotor, independent means for adjustably connecting the tan blade to the motor comprising a motor bracket including a base adapted to be snugly fitted against and directly secured to the rotor of the motor, spaced ears formed on the base and provided with centrally disposed and alined pivot bearings and with alined openings adjacent their periphery, a fan bracket including a plate upon which the adjacent end of the fan is adapted to be seated and to be directly secured, and an ear formed on said plate and having a pivot bearing adaptsa-id spaced ears and having a circular series of openlngs ad acent its periphery adapted to be selectively brought into regis-v ter with the peripheral openings of said spaced ears, a pivot pin operatively arranged in the alined pivot bearings of said ears, and a lock pin operatively arranged in the registering openings of said ears.
