To all 'whom it may concern:

Be it known that I, Mmron Kenn, a citizen of vthe United States, residing in the borough of Manhattan, city, county, and

State of New York, have-invented an Imtor fanlis constructed for ornamental pur-` poses as well as practical uses, and hence may be made in a casing of ornamental configuration and provided with means for ca'P member and parte guard or cage member the lampsy ,or other producing different facts. The present invention does not relate howeverfto theconstruction of the parts of the apparatus which produce the currents of air, but has to damore particularly with a surrounding the air current ,producer in order to add te the .orna-l mental eiect, te` guard against n'ury by contact with the revolving lades o the air producer and alsbllto .serve the purpose of conduits forcontaining the leads orelectric circuits lay-which the current is- 'conveyed to` ldevices employed fory reducing the eilects as will --be ereinafter more particularly described7px Inthe n Figure 1 isan elevation of my improjggd ventilator a'li'.- g" y 5,; Fig. 2 is a partial elevation and loigitudinal section thereof. f ig. .3 lis an enlarged inverted of the l lighting and other efsection illustrat'l 4 I I hollow rods or'lies c member. n. siieigw is financi tbetopplaie ce? member. 7. :gv 7. .i ig. 6 is aplanofftheblo to assist in maintaining the motoriniY position in thrwine and i, FigTis a di- :u f ticplan ofthe cir- 55. icuits employed the apparatns.

liglrd'blfcage portion' of the a paljand culminating in a' cup portion Within the cup portion 12 anelectric4 or any other `mfotor v13 is mounted on a U- shaped frame orstrap 14, resting upon the base of the cup portion of the casing and secured in tion therein b means of a block 41 5 made t0 fit within e neck 11 of the together with a bolt '16 fixed at one end'mthe yoke of the U-sha strap memberand adapted-bo be a'ssed t rough a bore provided therefor on t e blockv 15 with the parts secured in place by'means of a nut- 17 or otherwise. The peripheral? eur-` face ofthe -block 15 is provided with recasses 18 andl 19 for a purpose hereinafter The air current producer of the apparatus'I as illustrated, com rises a cone-shaped-member 20, bladey mem rs 21, and a rin 22, the bladememhers 21 being connecte at one end in the cone-shaped member and at their opposite ends to the ring 22. While these parte are thus connected to ther they are also to and onnte upon Vthe nio- `toi- 2 3'iiiany sui blemanner so. as to be thereby. mated the current' producer is so'conthatby the revolution thereof air caused to move first ina direction to the axis of rotation predetermined -paths at an an le thereto to 'diffuse the air as mov andthus ete circulation of the air in the y 'or other place ,to beven'tilated. features however, form `no part of my present invention and are more `particularly pliation 'Sefonelof the features o thev Y inpludes As hereinbefnm muy and then periphery o nature of this invention. At its outer end each hollow arm 24 terminates in a cup member 25 provided with a reduced extremity 26 and an internal flange 27. Within each cup member 25 there 1s a 11ning 28 of insulating material recessed to recelve a metal cone 29 rovidcd with a screw threaded bore as clear y indicated in Fig. 4.

A lead wire 30 passes through each, of the hollow arms 24 and is electrically connected in a suitable mannerto the corresponding metallicco'ne 29. At the oplposite or lower end as illustrated, each of t e cup members 25 is fitted with a plug 81 having an ornamental exterior configuration and secured in any desired yway to the cup member or the metal coneI secured within the same. This caseor frame structure also includes a series of tubes 82 corres ending in number with the hollow arms 2 and each tube'82 is provided with a 'linin 38 of'insulating material havin a bore t erethrough. The series of tubes 2 is suitably connectedto a plurality of bandsor rings 34 preferably of different diameters so as to cause vthe tubes 32 to assume an inclined osition in order to conform generell to t e inclination at which the blades of t e air current reducerr are set. The guard or cage mem 'r also includes a disk top 35 preferably o f insulat` ing material the upper surface adjacent the which 1S raised as indicated ai 36 while the ed thereof is flanged as indicated at 37 an the under surface recessed as indicated at 38. The surface of the raised portion is such as to preferably be at 1i ht angles to the axis of the tubes 32 while as will be understoodthe cup members 25 are so placed or lthe arms 24 so bent, as to cause these cup members 25 to be in alinement with the tubes 32 when the parts are assembled. It will now be understood that the frame or cage member comprises the'supporting arms 24 with their cups 2g, an s the-connected tubes 32 and rings or 3.4, and the top 85. In assem ling these parts the connected tubes and bands-are placed over the rblades of the air' current producer and fitted attheir lower or inner ends into the reduced portions 26 of the corresponding cup members 25 while at their up er ends the tube mem rs 33 fit withint erecesses Y38 of the to 35 which are so made as to receive them. 'ese parts 'are connected by means of bolts 39 which pass through openings in the raised part 36 on the top 35 and through the bores in the linings 8B of the tubes 32 there being a` bolt provided for -eaoh of these tubes and each olt havinga head at one end as indicated l at 40 withl a circumferential recess' 41 therein vwhile at the oiherlend each .bolt is sfre'w threaded so as to 4be turned down into the screw threaded here of the' spending metal cone 29. By this ineens at`v o'f contacts 47 which .ends the contacts are .at 49, tll Said L vo:

will be readily apparent the guard or cage which is an integral structure and separatelyremovable from the casin is connected thereto mechanically and e ectrically to secure these parts together and provide means for electrical clrcuits to electric lamps or other devices which ma be emplcgd for producing a desired decorative e Of course it will be understood that the bolts 39 may be madcwith permanent insulating coverin so as to be fitted into the tubes 32 instea of constructed as hereinbefore described, in which instance as will also be understood the o ening in the flan ed ortion' of the top plate 35 is sailicienty arge to Iseceivey the bolt with its insulating covering being of substantially the same diameter as lthe diameter o'f the insulation on the bolt.

Withthe structure as herein described I may also em )loy suitable means for changing the con ition of the air as it is discharged rorn the fan. The air may be chan ed by heating, cooling, perfuming, disin acting, humidifying, ozonizing, or otherwise treating it in the same or equivalent manners as are described in my lco- Eending application to which reference has ereinbefore been'made. For example, the rings or bands indicated at 84 may be in the form of tubes and provided with resistance coils which are suitably connected and disconnected in and from one of the electric circuitsto heat the tubes and thus raise the temperature of the airl as it is delivered from the fan. 4Suitable means also may be provided in these tubes for cooling the air or as hereinbefore stated,.means may be employed for perfuming, disinfecting,

humidiying or ozonizing the airhtliut these a shadev 46 or other ornamental device whic adaptsurrounds the laml bulb. The 'electrical connections are ma ve the bolts 39 to the lam'p socket and lamp bulb by means eralrfly4 insulated from the cap 42 b screws and an interveninglayler of ms'ula in lillaterial or otherwise. he contacts 4 are preferably o'il'set .at the corresponding ends thereof as indicated at'48 and 1n @sive the eircumfentielly: recessed portions are secured to and prefi these recessed as indicated: being adapted to re? of the heads 40 of cpbesitelv diseased een 1th a positive conductor and the others irrespecl tiveofytheir number as negative conductors in order to produce different lighting effects. It will furthermore be apparent that as illustrated in the smaller types of ventilator fans the guard or cage member may be made conical but in larger types thereof it may be advisable to make it hexagonal or octagonal, or even spherical, or in some other coniguration which however, has no bearing on the subject matter of this invention.

In the base 10 I prefer to employ a series of terminals indicated at 52, 53, 54, together with contacts indicated at 55 and 56, and a switch arm 57 which at one end is pivotally connected to the terminal 52 and intermediate of its ends is adapted to bear against either the contact 55 or the contact 56. The positive lead wire from the source of electricity to the ventilator fan is indicated at 58 and is carried`and connected to the terminal 52. A lead Wire 59 extends from the terminal 52 to the terminal 53 and to one of the terminals of the light socket, and as will be understood, this lead Wire as diagrammatically indicated in Fig. 7 includes the lead Wire 30, a conductor bolt 39, a contact 47, and either of the lead wires 50 or 51 as hereinb'efore described. 4A lead Wire 60 extends from the other terminal of the lamp socket to the contact 54 which is connected by alead Wire 6l to the negative line, and the lead 60 of course includes either one of the lead Wires 50 or 51 and the other side of the circuit includes one or all of the other conductor bolts forming part of the guard or cage. A lead Wire 62 extends from the contact 54 to one of the motor terminals while the other' motor terminal is connected by a lead 63 to the contact 55. From the diagrammatic plan as shown in Fig. 7 it will be apparent that the light may be usedy a vertical position and at its lower end made to turn in a thrust bearing, if it were not properly ventilated it would overheat in a comparatively short time unless a motor of considerably larger capacity were employed than is necessary to operate the fan or air current producer, which even then if not ventilated would produce an excessive,

amount of heat. In the structure as herein indicated it is to be noted that a series of openings 64 are provided in the casing beneath the motor for the admission of air so that through the operation of the fan or 'air current producer there is a positive draft or current of air circulated around the motor at, all times so as to adequately ventilate the interior of the casing and maintain the motor at an eliicient Working temperature by coolin the interior a's well as the exterior of t e motor, which of course permits the use of a motor of smaller capacity than would otherwise have to be employed, the y air currents passing through the openings 64 and through the Ventilating recesses 18 in the block 15 as hereinbefore described, as well as through the space provided for thispurpose between the exterior of the motor and the interior of the casing. I

As herein described the casing or frame is an ornamental structure in which the motor is mounted and the device supported, but as will be understood in some instances this casing may be dispensed'vith and the guard or cage connected to the frame of the motor either directly or through arms or other suitable supports'projecting therefrom in the same manner as the arms herein described extend or project from the casing.
