FAN CONSTRUCTION.

$PECIFICATION forming part of Letters Patent No. 741,107, dated October 13, 1903.

Application filed April so, 1903. Seriall ic.156,057. (NomodelJ T ctZZ whom it Duty concern:

Be it known that I, WORLEY WALDEN BURNES, a citizen of the United States, residing at McCoy, iu the county of Kaufman and State of Texas, have invented certain new and useful Improvements in Fan Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled [O in theart to which it appertains to make and use the same.

My invention relates to fan construction; and it consists of certain novel features of combination and construction of parts, the

preferred form whereof will be hereinafter clearly set forth The prime object of my inventionfamong others, is to provide a fan which. shall consist of a few actuating parts, comprising a spring-motor which may be easily and quickly wound and when wound provides power for many hours.

A further object of my invention is to provide simple though reliably efficient means 2 5 for adjusting the blades of the fan whereby they may be disposed in any preferred position and deemed productive of the best "resuits.

Another' object is to provide means for. readily adjusting the height of the fan from the table or desk.

Other objects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings, which 35 are made a part of this application, and in which- Figure 1 shows a side elevation of my invention applied to use. Fig. 2 is a detail view showing means for readily adjusting the blades of the fan proper whereby they may be disposed at any desired angle. Fig. 3 shows means for adjusting the height of the fan from the ceiling. Fig. 4.- is a sectional view of the motor, showing the preferred arrangement of the train of gears and actuating spring therefor. Fig. 5 is a top plan view of the fan-blades and accompanying parts. Fig. 6 is the cross-bar to which the fan-blades are secured. Figs. 7 and 8 show means for 50 adjusting the relative position of the fanblades.

Referring to the various details of my invention and cooperating accessories, numerals will be employed, the same numeral applying to a similar part throughout the several views.

Referring to the numerals on the drawings,

1 shows the casing of any preferred size and shape, designed as a housing for the motor, which consists of the actuating-spring 2, operatively connected with the master-Wheel 3, which latter is in mesh with the power-communicating wheel 4, which is journaled on the shaft 5, having suitable bearings in the brackets or cross-bars 6 and 7, which latter are connected with each other by means of the depending arm 8 or the equivalent thereof. To the lower end of the shaft 5 I secure the gear-wheel 9, which is in mesh with the gear 10, carried by the upper end of the shaft 11, to the lower end of which is secured the fan-carrying arms or bar 12, which is provided centrally with a square aperture 13, designed to receive the similarly-shaped end of the shaft 11, a suitable set-screw 14 being provided to insure a union of said parts.

It will be observed that the master-wheel 3 is mounted, as is common, upon ashaft 15, the outer end of which'receives the windingkey 16, while a suitable pawl and ratchet 17 is also provided to hold the master-wheel against reverse rotation while being wound, as is common.

The fan-blades 18 may be adjusted by means of the toothed bar 19,which is provided with the longitudinal slot 20, which is adapted to receive the end of the bolt 21, which at the point where it passes through said slot is square in cross-section. The bolt 21 is also squared, so as to be received by the square 0 aperture 22, formed in the outer end of the arm 12, so as to insure'that the plate 19 will be held in a true vertical position with its cogs or teeth pointing outward and adapted to mesh with the segmental toothed bracket 23. g5

The segmental bracket 23 is provided with an arm 24, having apertures 25 and 26. The aperture 26 is adapted to receive the bolt 27 which passes through a registering aperture provided in the fan or blade 18, while the ap- 10o erture 25 is'intendedtoreceive the bolt 28, which passes through registering apertures in the inner end of the fan or blade and also through the aperture 29 in the extreme outer end of the arm 12, and it is therefore obvious that the bolt 28 forms a pivot-point by means of which the outer end of the fan or blade may be raised or lowered through the mediation of the rack-bar 19 and the segmental bracket 23. It is therefore clearly obvious that by loosening the nut upon the bolt 21 the rackbar 19'may be raised or lowered, as desired, which will incidentally lower or raise, respectively, the outer end of the blade 18, thereby enabling a proper adjustment of said blade to be quickly etfected,when the nut upon the bolt 21 may be tightened, thus locking the blade in an adjusted position.

To the upper side of the housing 1 I secure the tubular extension or elongated socket 33, which is adapted to receive the lower end of the shaft 34, said shaft being secured in said socket, as by the set-screw 35, thus enabling the motor and fan carried thereby to be raised or lowered to any desired point. It will thus be seen that I have provided simple though effective means for adjusting and securing the fan-blades in any desired position, and While I have described the preferred combination and construction of the various parts deemed necessary in materializing my invention I desire to comprehend such substantial equivalents and substitutes as may be considered as fairly falling within the scope of my invention.

Believing that the advantages and manner of using my improved fan have thus been made clearly apparent, further description is ward from the housing of the motor, adapted to adjustably receive the end of a depending shaft, in combination with a driving-shaft 1 l connected with said motor and extending downward below the same; a cross-bar or pair of arms 12 connected to the lower end of said shaft; and each arm carrying a rack-bar adjustably connected to its end; a pair of fanblades each having at its inner end a segmental toothed bracket 33 adapted to mesh with one of said rack-bars and means to change the relative position of said parts whereby the fan-blades will be adjusted and secured at any desired angle all combined substantially as specified and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses. I

WVORLEY WALDEN BURNES.
