Description

WILLIAM E CAKES, 0F INDIANAPOLIS,YINDIANA.
FAN.
Specification of Letters Patent.
Patented Apr. 16, 1912,
Application filed October 12, 1911. Serial No. 654,287.
To all whom ttmay concern.
Be it known thatI, WILLIAM H. OAKES, a citizen of the United States, residing at- Indianapolis, in the county of Marionand State of Indiana, have invented a new and useful Fan, of which the following is a specification. j g
It is the object of my invention to improve and simplify the construction of fans. In carrying out my invention, the fan blades, which are preferablymade of a single punching with integral rings connectingtheir outer, and inner ends respectively, are connected to a rotatable, annular central support by int-erfitting projections and apertures, which are clamped in interlocking position by a suitable cap, preferably the dust cap for the fan bearings.
The various novel features of my invention will appear from the description and drawing and will be particularly pointed out in the claims.
In the drawing, which illustrates a pre-- ferred embodiment of my invention, Figure 1 is a complete end elevation of a fan embodying my invention; Fig. 2 is a somewhat enlarged longitudinal partial section through such fan substantially on the line 2-2 of Fig. 3; and Fig. 3 is a fragmentary view, with some parts removed and broken away, showing the'central part of the fan.
The stub shaft 10 is provided with bear ing cones 11 and 12, the adjustable bearing cone 12 being held in adjusted position by a nut 13. Bearing balls 14 are located between the bearing cones and suitable ball races 15, mounted on the inside of a tubular hub 16 and spaced apart by a spacing tube 15 held in place in the hub 16 by an oil cap 16. Suitable dust guards 31 may be provided in the bearings. On one end of the hub 16, which is preferably made of steel tubing, is a pulley 17 or other suitable power-transmitting device, and on the other a collar 18 having an annular flange 19. The parts 15, 17 and 18 are preferably all made of pressed steel and the parts 17 and 18 may conveniently be fastened to the hub 16 by electric spot welding.
Mounted on the flange 19 is the fan blade structure, which preferably comprises a central ring 20, skewed fan blades 21, and an outer reinforcing ring 22, the rings 20 and 22 respectively connecting the inner and outer ends of the fan blades and with them forming one integral structure. This cap 30, the collar 18 structure may conveniently be a stamping of sheet steel. The reinforcing ring 22 may be spun around a strengthening wire 23, if desired. 'To strengthen the inner part of the fan blade structure, the blades may be riveted to a spider comprising a ring 24 and arms 25.. The rings 20 and 24 are preferably of the same size, and their inner edges fit over a shoulder 26 on the flange 19, one face of the ring 24 hearing againstthe face of such flange. The flange 19 is'provided with a plurality of notches 27, to receive ears 28 punched in the rings 20 and 24 and bentout of their plane.v The ears 28 are held in the notches 27, and the rings 20. and 24 against the flange 19, by a flange 29 of an internally threaded dust being threaded to receive such dust cap, which isalso preferably a sheet steel stamping. The removal of the dust cap 30 allows the removal of the blade assembly in its entirety, or the removal or adjustment of the adjustable bearin cone 12, or the removal of the hub 16 an the parts carried thereby from the shaft.
My invention is not limited in its details to the precise arrangement shown, and I aim to cover all modifications which do not involve a departure from the spirit and scope of my invention as set forth in the followin claims.
What claim as new is:
1. A fan structure comprising a flanged hub, a spider carrying a plurality of fan blades, the spider and the flange of the hub having interfit-ting projections and apertures, anda cap closingthe end of the hub and clamping the spider and flange together and the projections and apertures in interloclc ing position.
2. A fan structure comprising a flanged hub, a spider carrying a plurality of fan blades, the spider and the flange of the hub having interfit-ting projections and apertures, and a cap clamping the spider and flange together and the projections and apertures in interlocking position.
3. A fan structure comprising a shaft, a flanged hub rotatably mounted thereon, a plurality of fan blades, said fan blades and the flange of the hub having interfitting projections and apertures, and a cap closing the end of the hub and clamping said projections and apertures in interlocking position,
'4. A fan structure comprising a shaft, a flanged hub rotatablyimounted thereon, a plurality of fan blades, said fan blades and the flange of the hub having interfitting project-ions and apertures, and a cap clamping said projections locking position.
5. A fanstructure',
and apertures in intercomprising a, shaft, a
hub rotata bly mounted on the shaft and,
having a circular flange, a plurality of fan blades connected at their inner ends by a ring integral with the blades, said ring hearing against the flan eon the hub, and said ringvand' flange having interfitting ears and openings, and a threaded on and closing the end of the hul and clamping said ring 7. A fan structure comfprising a stub shaft,
a hub having a notched ange, ball bearings between the shaft and hub, a plurality of fan blades connected at their inner ends by a ring integral with the blades, said ring bearing against the flange of the hub and a plurality of fan vhaving integral projections extending into the notches of said flan e, and a flanged dust capthreaded on and c osing the end of the hub, the flange of the cap clamping the ring and the hub flange together and the projections in thenotches.
8. A fan structure comprising a stub shaft, a hub having a notched flange, ball bearings between the shaft and hub, a plurality of fan blades connected at their inner ends by a ring integral with the blades, said ring bearing against the flange'of the hub and having integral projections extending into the notches of said flange, and a flanged cap threaded on the end of the hub, the flan e of the cap the 'ub flange together and the projections in the notches.
9. A fan structure comprising a flanged hub, a flanged cap fitting on the end of said hub, and a spider carrying a plurality of fan blades and located between the flange on the hub and the flange on the cap, sald spider and one of said flanges having interengaging projections and apertures.
In 'witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana. this 10th day of October, A. D. one thousand nine hundred and eleven.
