To aZZwhom it may con-cem: i

YBe itknown that I, AlHoMAs H. PITHER,

. citizen of the United States residing at Chicago," in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Ceiling-Fan Motors, of which the following is a full, clear, concise, and exact description..- l

My invention relates `to motor driven mechanism of the type wherein the driven 'member surroundsthe driving member kand is rotated thereby; l The vobj ect of my invention is to provide a simple and compact structure, maximum efficiency, with a minimum of My invention provides a structure wherein a highspeed motor ma be used and any desire variation of speer of the driven member obtained without com' licated gearing and lpa'rrangemefnts` My invention consists of a rotatable member surrounding a motor and c lriven'tliereby, the driving element of the motor being movably adjustable with relation to the rotatably- /tljie gearing engagement therewith and thereby to control the speed at which. the rotatable `niemberis driven. i f f 'In the preferred embodiment of my invenpivoted in a Jframe to swing on a horizontal axis and the driven member Acomprises a casing rotatably mounted on the vframe and having an annular portion in en` gaveme'nt witha driving gear carried on the en of the motor shaft.

The engagement of the gear with the annular ing is thus rendered adjustable byswinging the motor' on its pivots. Y A further feature of my invention consists inthe means ofmountingtlie casing` on the supporting frame or bracket, the bearing for -A the rotatable casing comprising an oil-cu mounted upon 'the supporting frame.

IAnother feature of my invention consists in the 'p articular means. employed for swinging the motor on its pivots, said means comprisiiig a link and ratchet mechanism by.

means of which the motor may be adjusted and held in its adjusted position.

In the accompanying drawings I have shown myirivention embodied in a ceiling fan.

f AThe various feaftures of 'the invention may' i Specification of Letters Patent. Application sie@ August 22,1907. serai Np. 389.621.

having a Patented Dec. 24, 1907 I be readily understood by reference to `said I drawings, in which Figure lisa side elevation of a ceilin fan; Fig. 2 is aside elevation-showing, by lfu and dotted lines respectivelyJ two positions of the adjustable elements, the casing being shown in section; Fie'. but taken at right angles thereto; Fig. 4 is a .fragmentary detail sectional 'view' of the link -an ratchet mechanism for adjusting the mopr; and Fig. 5 is a section on'the line 5-5 of Jike parts are desi nated by similar characters o f reference t roughout the several views. f`

The electric motor M is mounted on horizontal ivots 1, 1, upon diametrically opposite, si( es of a ring-like frame or bracket 2, which is suspended in the usual manner u 'on the lower end of a standard or hanger 3. 'ilhe means for swinging or 'adjusting themotor link/connection, the upper member 4 of which is pivoted at its free end to, the frameof the motor and the' lower member 5 is pivoted intermediate its ends upon a pin 6 in the lower portion of the frame 2.

terior curvature of a sphere, the center of whic is the pivotal point 6. The lower end of the lever5 extends through aslot 8 in the part 7', and forms a handle 9 for operating the toggle-lever- Ratchet teeth y10 are videdupon each side ofthe slot S.' The le` ver 5 cariies a pawl comprising a pin 11', slidable longitudinally of the lever and having a spring-thrust engagement .to hold it in its adjusted" position between the teeth 10. By operating tlie handle 9, therefore, the toggle lever may be operated to swing the motor to any desired position and the-parts will be heldin their adjusted positions.

and frame 2 said frame 2.

of leather, paper or other suitable'substance, which'has'frictional engagement Awith the driving gealr 14 of the motor.

The driving' gear shown in the drawings is the well-known spring-thrust steel'disk 14 carried upon the end of the motor shaft.

upon its pivots comprises a toggle lever or IThelower end of theframe .2.has the eX;

pro-

rThe driven member carrying the fan blades preferably comprises a hemispherical or bell-V shaped casing 12, surrounding -the motor M' and journaled at its apex upon I also preferably secure upon the periphery of the easing an annular rim 13 TWO of these, upon' opposite ends of the shaft, may be employed, and their errengement thus, 180o np'zirt, equelizes the loedend insures uniform turninrT movement.

in the position of the parts shown in full lines in F '2, the center of the disk 14 is in engagement with the rim 13 in which position the motor. receives no current, sinee, es shown in Fig. 4, the switching mechanism 15 is in its open position. nnism is preferably of the type of snepswiteh shown in United States Letters Pntent No. 82h52?, te Herold 1t. Nellnmin issued Mey Sth, 1906, sind hence needs no detailedy description. l adept seid snapswitcli for use in connection with in v invention by providing the link 16 thereof with n. biiurrntedend, or with prongs 1?,.171. in the normnl or inoperative position of the inn, e lug 1b upon.,the link 4 lies between seid prongs.V In moving' the handle 9 one iioteh or to the 'lirst operative position, seid lug engages with the prong 17, moving` said prong` out of tno pero -oi sind lug, :ind throwing the switeh 15 into its closed position. At the seine time, sind movement of the link 1G on its )ivot throws the iron" 17 in io'sition to be engaged ,by the lug lin its return inove-v ment,` and henne in moving the handle 9 to its initiel position from its iii-st or slowest' speed position the switch ilis thrown: open and the parts restored to the positions shown'` in Fig., 5. By this simple arrangement, the first movement of the operating liendle in one direction elosesthe switch, end the last movement in the reverse direction opensthe seme.'

As shown most clearly in Fig. 2, the movenient oi the handle 9 operates the toggle iinks and swings the motor on ,its horizontal pivotal exis, thus ehn-ligging 'the radial enffegement of the disks 14 vwith the annular {iii-nge or riin 13. The more said inotor is tilted, the festerthe speed et whien the easing 12 is ro tated, es is readily npperent. 1 l

As isweltknowinn high-speed motor is of simpler construction, more compact, and

cheaper to iniiiiiifneture-tlni.n n low-speed motor. W'ith the eiriingei'nent vdescribedV i am enabled to employ e high-speed motor of,y

As before started, l pi'eternlily employ n. heniispheiienl or bell-shaped (raising 12 sui'- rounding the motor iind the supporting freine 2, sind 'lrnine having threaded openings 19 for rereiving the t'zin blades. An oil eup 2l) mounted on the top of the freine 2 `end preferably enst integral therewith forms n bearing for the rotntnble rinsing l2. The npex of sind easing surrounds the exterior of seid eup, and luis e. tubulin' llnnge 21 which Seid switeliing nieehextends downward into the cup and rests upon e Washer 22. Said iinge 21 surrounds e,- tnbulsrsleeve 23 secured to freine 2 and byj means of which said frame is suspendedifrom the heneer 3.

The riower -helf of the operating parts may be surrounded by the usuel easing 24 tixedly mounted by screws or otherwise upon bracket ernis 25 extending outwardly frein-the freine 2.
