rare.

.To all whom 'it may concern:

1Be it known that I, HARRY MANEs, a' citizen of the United States, residing at Jersey City, county of Hudson, and State of l .considerably from other motors of this class for a similar purpose.

-My improved motor operated fan is intended for usel more particularly 'where' an electric current is not available,and also by those who cannot aord to purchase an electrically driven fan.

I will now proceed to describemy invention, the novel features of which I will finally claim, reference being had to the accompanying drawing, forming part hereof,

wherein-M Figure l illustrates a verticalsectional view of my improved device, certain parts being shown in elevation Fig. 2 is a sectional plan view thereof, the section being taken on a line a-a in Fig. 1, and Fig. 3 is an enlarged fragmentary sectional view of the spring casing and brake therefor.

Referring nowv to the' drawing the numeral lwi'ndicatesthe casing of my improved device "within which the motor parts are mounted. The power exerting element of my `improved device comprises a clock spring 2one end 43 of which is' secured to a casing 4, the'inn'erend 5 being secured to a rotatable shaft 6. Upon the shaft v6, and secured to the casing 4, I'loosely mount a gear 7, which is adapted to mesh with-an intermediate pinion 8, secured to a rotatable shaft 9. Upon the shaft'9, I also secure 'an intermediate gear 10, which-is adapted to mesh with a'pinion 11 secured to a shaft 1 2. The shaft 12 carries a crown-gear 13, which in turn meshes with a pinion 14 mounted upon the lower endof the verticalshaft .15.,

vThe shaft 15 is rotatably supported by atubular support 16, which in t rn is secured `to the frame 1 by a set screw 1y 'The 'upper Aer1/d of the shaft 15 carries a pinion 1.8 vvh1ch meshes with a gear 19, which inturn is carried by a shaft 20. The shaft 20 has mounted thereupon a1 fan 21, the said shaft 2O being supported by Ia bracket 22, which in turn 1s carried by the tubular support 16.

As can beseen in Fig. 1 the casing 1 is secured to a table 23, which is adapted to' rotate upon a ring 24, which .is suitably supported'by a base 25.` rIhe ring-24, upon the inside thereof is provided with gear teeth 2G, with which a gear 27 is adapted to mesh. The gear 27 is carried by a spindle 28, which at its upper end carries a loose gear 29 provided with a clutch-jaw 30. Adjacent to theclutchjaw 30, and upon the spindle 28, I mount a. clutch-jaw 31, which'is longitudinally movable upon and splined to the shaft 28 as at 32.

ment with the clutch-jaw 30 I provide an operating lever 33.

To control the speed of the motor, and also to holdthe mechanism against .movement while the spring 2 is being wound up, I provide a brake shoe 34 which is placed upon the casing 4'as shown in AFigs-1 and 3. To causethe brake shoe 34 to oppose the rotation of the casing 4, I provide at thumb screw 35. y

It is quite apparent that when the casing' 4 is caused to rotate by the reaction of the springQ, after said spring has been wound up, the fan 21 will be caused to rapidly revolve through the medium of the gearing Vbefore described. Should the clutches 30 and 31 be caused to engage, the gear 27 will rotate simultaneously' witlr'the crown gear 13. As thev gear 27 and gear teeth 26, vof the ring 24, are in mesh, the table 23 will be caused to revolve, whereby the fan 21 will travelv in a circular path while it is being rotated. Should I desire to keep the casing 1 stationary', while the 'fan 21is being revolved, Ikeep thel clutches 30 and 31 out of engagement, for instance as illustrated in Fig. 1.

To move the clutch-jaw 31 `into and out of engage- By meansof the vbrake shoe. 34 andr setscrew 35 I am able .to control the speed of the fan. When I desire to wind the spring 2, I force the brake shoe 34 firmly against the casing 4. The spring 2 is of the. ordinary clockA spring variety and is. therefore lwound up .in the same manner, a ratchet 36 and pawl being provided for thecusual purpose.

Alfter having wound thelspring I.' can vhold the` operating mechanism of the' motora) stationary by means of the shoe'e and screw 35. By releasing the screw 35 the motor will operate, the speed thereof being goV-. erned by' the pressure of the shoe upon the casing Having nonT described my invention what l claiin and desire to secure byl Letters Patent isz-s f Arinotor operated fan', comprising a rotatable casing, spring actuated gearing Within said c'aslng, a crown gear VWithin ysaid casing adapted for operationby the spring actuated gearing, .a table secured to said 'casing rotatably'mounted upon a base therel ..for, a ring interposed between said baseV and Y said table, gear -teeth carried by said ring,`
