Fig. 6 is a sectional viewon line 6 6 of Fig. 2.

Fig.V 7 is a diagrammatic view showing the electric circuit.

A at, circular, heavy base 10 is supported upon a floor 12, and may be bolted thereto if desired. Centrally of the base, an upwardly opening, cylindrical, flanged socket 14 is bolted to the base. Threaded into the socket is the lower end of an elongated, vertical tubular standard 16. External threads are provided on the standard intermediate its ends, said threads being closer tothe lower part has been than to the upper end of the standard.- A sleeve 18 is internally threaded for engagement with the threads of the standard, the standard extending upwardly through said sleeve. On the upper end of sleeve 1S, an outwardly directed, circumferential flange has spaced apertures receiving bolts connected to a flat table 20 of circular outer conliguration, formed to a large diameter to permit a number of persons to be seated therearound. Table 2t) has a center opening through which standard 16 extends and is made rigid by a plurality of supporting posts 17 having end flanges 19 which are in turn secured to the top f of the base 10 and to the bottom of the table 20.

A at, circular condiment holder or Lazy Susan 22 of substantially smaller diameter than that of the tablev 20 is centrally provided with a depending, circular boss Patented Dec. 6, 1955 threaded to engage internal threads on a connecting ilange 28 having a circumferential series of apertures receiving bolts 30 passing through registering apertures spacedV about the center opening of a ilat, horizontally disposed, circular plate 32.

Spaced 90 apart about the outer periphery of plate 32 (Fig. 3) are angle brackets 34 of L-shape, each having a horizontal leg bolted to and arranged radially of plate 32, and a vertical leg extending upwardly from the horizontal leg. The vertical legs are apertured to receive bolts, that pass through registering apertures of a cylindrical housing 36. Housing 36 is formed open at its upper and lower ends, and is vertically disposed inconcentric relation to standard 16 and plate 32. The marginal portion of the plate is in contact with the inner surface of the housing, intermediate opposite ends of the housing, but closer to the lower than to `the upper end of the housing.

A circular bottom plate 38 is of a diameter equal to that of plate 32. Plate 38 is spaced from plate 32, being disposed below the plate 32 in contact with the inner surface of housing 36. Bolts 40 arranged in an annular series pass through registering openings of

plates

32, 38 to ixedly connect the same. Mounted in openings formed in plate 38 (Fig. 4) are vertically disposed lamp sockets 42, opening downwardly to receive depending lamps 44, disposed to cast their beams upon the table 20.

On the upper end of standard 16 (Fig. 6) a lat, circular plug 46 of wood or the like is Seated. A vertical, tubular shaft housing 48 has a permanently closed lower end 50 engaged against plug 46, housing 48 being externally threaded at its lower end to engage internal threads of a coupling sleeve 52, thatis also engaged with the upper end of standard 16. A quantity of oil 54 or other lubricant is provided in shaft housing 48, and extending within the shaft housing 48 is a vertically disposed, solidly formed spindle or stub shaft 56, the upper end of which projects above shaft housing 48 and supports the center poitionlof a ilat, circular center plate 58 of a fan blade structure. f

A circumferential series of openings formed in center plate 58 receives downwardly extending connecting bolts 60, passing through registering openings of the horizom tally rotating pulley 62 circumposed about shaft housing 48, out of contact with the shaft housing. A belt 64 is trained about pulley 62, and also (Fig. 3) about ak the table top 20, and connected in series with the motor` are the several electric lamps. Thus, a conductor 76 extends from the motor through a notch 78 formed in the marginal part of plate 32. Cord 76 (Fig. 4) extends to one of the lamp sockets, and extending from said one lamp socket is a lead 80 to the next lamp socket, another lead 80' being extended to the last lamp socket. A lead 82 extends from said last lamp socket into standard 16, and also extending into the standard 16 is a lead 84.

Leads

82, 84 are connected to opposite sides of a 3 switchA $6 mounted upon. the underside of table 20 (Fig. l). l

An electric plug 87 connected to lead 76 is adapted to be plugged into a receptacle that is provided upon the motor, to. connect the switch and lamp electrically to the motor; The arrangement is such as to cause movement of the switch to on position to be eiective for closing a circuit through the. lamps a-nd motor, to operate the motor for turning a fan blade structure, simultaneously wth illumination with table 20.

The fan blade structure includes a tlat, horizontally disposed blade support plate 88 that overlies and is spaced above the open upper end of housing- 36. AV center opening of blade support plate 8S receives downwardly extending bolt 90 (Fig. 6) threaded into an upwardly opening, axial socketof spindle 56,. said bolt also being threaded into a center opening of plate 58. spindle or stub shaft 56, plate S, and plate 88 are all connected for joint rotation, the bolt 90 having a washer that bears tightly against the plate 88 to bind the same against rotatable movement relative to plate 58.

Integrally formed upon the marginal part of the plate 88 is a depending skirt 92, formed to` an inner diameter slightly greater than the outer diameter of housing 36, and slightly lapping the housing 36 as best shown in Figs. 5 and 6.

Recesses 94 are formed in the skirt (Fig. 2) and extending through the recesses are fan blades 96. Four blades, spaced 90 apart, are provided in the illustrated example. However, the number can be increased or decreased as desired.

Blades 96 are pitched obliquely to the horizontal plane in which they rotate, so as to direct air downwardly toward the table top Blades 96 are formed, intermediate their ends, with downwardly opening notches 98 of rectangular shape, said. notches being provided in the lower longitudinal edges of the blades 96 and receiving the upper end of housing 36. Also formed in blades 96, at the inner ends thereof, are right-angular recesses 100 providing a clearance for the marginal portion of center plate 58.

The upper longitudinal edges` of blades 96 are integrally formed with attaching anges 102 lying in horizontal planes. Overlying anges 102 in contact therewith, and arranged longitudinally and centrally of flanges 102 are downwardly facing channel bars or arms 104. Arms104 have openings receiving` bolts 106, passing also through registering openings. of flanges 102 to xedly secure the blades to the arms. The inner ends of the arms project inwardly a substantial distance beyond the inner ends of blades 96, and are interposedtas spacers betweenplates 98, 88. Registering openings are formed in plate 88 and the inner end portions of the arms 104, receiving bolts 108- that fixedly connect` the arms to the plate 88.

By reason of the arrangement illustrated, the major portions of the fan blades are disposed externally of housing 36 to direct cooling air against the users of the table. However, the blades also have inner end portions, constituting the parts of the blades that extend from the inner end of the blades to the notches 98 within the housing 36, which direct cooling air downwardly within housing 36 against motor 68.

It is to be noted that the lubricating oil 54 sup*- ports the entire fan blade structure in the illustrated position, and of course., in a commercial embodiment, a suitable packing gland might be provided. at the outer end of the shaft housing 48 surrounding the spindle; 56, to insure against leakage of oil between the.A contacting surfaces of the spindle and shaft housing. The: oil, at the same time, lubricates theV stub shaft bearing. defined by housing 48, during rotation of thefan blades structure.
