' Filed Aug. 4. 1930 2 Sheets-Sheet 2 @www Patented Nov. 29V, 1932 UNITED STATES PATENT OFFICE LAURENCE M. PERSONS, OF ST. LOUIS,.MISSOURI, ASSIGNOR TO EMERSON ELEUIRIC MANUFACTURING C0., F ST. LOUIS, MISSOURI, A. CORPORATION OF MISSOURI FAN Application filed August 4, 1930. 1 Serial No. 472,848.

My invention relates to an improvement in fans and has for one `objectthe provision of a fan which willdeliver air generally laterally in ali directions. Another object is the 6 provision of a fan `adapted to deflect the a1r from a. vertical to a horizontal direction of movement.. Another object is the provision of a fan of the above type adapted to deliver a breeze simultaneously in a plurality of di- 10 rections. Another object is the prevention n of torsional vibration in the fan and the prov duction of quiet operation. Another object is the provision ofv a fan adapted to be combined with a lamp whereby a single installation for 'example on a desk or table, may serve the double function of illumination and of draft or air current production. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention morelor less diagrammatically 1n the accompanying drawings, wherein Figure 1 is a vertical section; Fi re 2 is a section on the line 2-2 of Fi ure 1; and

igure 3 is a section on the line 3--3 of Fi re 1.

ike parts are indicated by like symbols throughout the specification and drawings.

Referring to thedrawings, A generally indicates a lamp base, which may include the stem A1 and the supporting foot A2.

Mounted within the lamp shell A is a motor housing structure which may include the outer housing or shell B which carries the eld coils B1. B2 indicates a bearing sleeve and B3 a cover orclosure for the shell B. The structure so formed is supported within the shell A, for example, rby the bolts or screws B4, the heads B5 of which abut against countersunk preferably yielding or anti-vibrational bushings or washers B6. The inner ends of the upper screws B4 pass through apertures in a ring B7 associated with the cover plate-B3. The motor structure is thereby centered in and supported in the shell A, and rattle or vibration is prevented by the yielding washers.

Projecting upwardly through the motor structure is the fixed shaft C the lower end rod frame work are a plurality of air deectof which is iixedly supported in any suitable fashion in the bottom of the hub or sleeve B2. Fixed in relation to the upper end of the shaft C is the sleeve C1, which may be locked in relation to the shaft C, as by the set screws C2. Associated with the upper portion of the sleeve C1 is a gear reduction housing C3, which'also serves to support a'combined cover and electric light support C4 herein shown as in the form of a concave disc, which may support any suitable number of light sources, for example incandescent bulbs C5. The wiring therefor is not herein indicated; but it will be understood that they may be connected in any suitable manner, for egrample, with a source of commercial electric power. C6 is in effect an upward or interrupted continuation of the fixed shaft C and, like it, is fixed against normal movement in relation to the sleeve C1. It supports at its upper end a sleeve C7 to which is'secured a concave cover memberv Cs.

Surrounding the above described structure is a frame work herein shown as a truncated cone which includes the upright rods D, the upper circumferential circular rod D1 and the lower circumferential circular rod D2. The lower rod D2 is supported by the radial rods D3, the inner ends of which are secured as by the screws D4 to the exterior upper edge of the lamp base A. D' are any suitable circumferential reinforcing rods or guard members.

Mounted upon the above described wire or ing vanes E, herein shown as circumferential rings the inner portion of which inclines downwardly and inwardly, the outer edge of which inclines somewhat downwardly and outwardly. In practice these vanes are curved or set at any desired arc or angle, in order to deflect an upward flow of air through the lamp body and to direct it outwardly and more or less downwardly. The contour of the individual vanes may of course be varied widely, depending upon the use to which the device is to be put and the desired angle or direction of deliveryof the ilow of air.

Mounted for rotation about the shaft C is the fan hub G. Mounted on the hub are the 100 inclined fan blades G1, which are preferably so inclined, in relation to the direction of rotation of the fan, as to direct an upward circulation of air through the device. The fan is concealed, laterally, by the deflector E1, which extends downwardly from the outer edge of the lowest of the vanes E and is herein shown as curled about the circumferential rod or support D2. The lower portion of the hub G is herein shown as attached to the armature sleeve or bearing G2, associated with which is the rotating armature G3 of the earlier described motor. The sleeve is shown as resting on the ball bearing structure G4 within the motor sleeve B2. The upper end of the sleeve G is laterally expanded to form a pulley or driving member G5, about which passes a belt G6 which in turn drives a pulley G7 mounted against rotation in relation with the shaft G8. The shaft G8 rotates in a sleeve G9 which forms part of or is associated with the earlier described sleeve C1. At its upper end said shaft carries the worm G10 in mesh with a gear G11, which in turn rotates a worm G12 in mesh with a gear G13. The gear G18 serves to rotate the sleeve G11; which has associated with it the laterally extending supportingdisc G15 upon which are mounted rotating baffles G1, the lower edges of which are spaced and supported by the circumferential wire or support G17.

It will be realized that Whereas I have described and shown a practical and operative device, nevertheless many changes mi ht be made in the size, shape, number and dlsposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken in a broad sense diagrammatic and illustrative rather than as limiting me to my specific showing.

The use and operation of my invention are f as follows I provide an improved form of combined lamp and fan in which a fan is concealed and housed and protected. The appearance of the usual type of desk fan has long been recognized as objectionable; and it is also an annoyance if only adding to the clutter of mation of the hand of the operator. I have diagrammatically shown a protecting and reinforcing structure including the rods D3 and D5. It will be understood that these parts are preferably so spaced and proportioned as to make it difficult or impossible for the operator involuntarily to insert a finger within the fan structure. Thus the fan is far safer to use than the ordinary conventional fan with exposed blades or with blades inelflciently housed in more or less open metal screen.

The vanes E serve as a shade for the lamp, it being if desired so proportioned as to prevent the escape therethrough of any substantial amount of light from the bulbs C5. Rotation of the motor, and thus of the fan G1, draws air upwardly into the lamp shade area. This air is constrained to pass voutwardly between the vanes E. These vanes are so formed as to convert the upward movement of the air into a lateral movement. In the form of vane shown in Figure l herein, the air delivery will be somewhat downwardly toward the table top, and the table top itself serves as an additional deflector or spreader of the air circulation.

In order to increase the penetration of the air current, I may provide the rotating baflies or shutters G16 which revolve on the inside of the shade, allowing the breeze to be thrown, in the form herein shown, only in two opposite directions.

The spoke mounting of the motor upon the screws or spokes B4 eliminates the torsional vibration from the shell and base of the lamp and produces quiet operation.
