FAN EVRQTOFL Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed June 24.19051 Serial No. 266.308.

The invention consists in the novel form of gearing hereinafter fully (lescri ed, pointed out in the claims, and shown in the acconipanying drawings, in which" Figure 1 is a front elevation of my device. Fig. 2 is a side elevation. 3 is a sectional view of a gear-wheel, a ratchet, and a pinion, a part of the shaft being also in section. Fig. 3.

1n the drawings, A r esents the bascboard or back, upon which is car ied a metal frame A, and in the frame are journaled shafts B C, D, E, and F, all in vertical alinement, as shown in Fig. 2.

The shaft B carries a gear-wheel B, which is fastened to the shaft, and a ratchet B is arranged loosely upon the shaft B, iacent the gear-wheel B, and a pawl B earned by the gear-wheel B, engages the teeth of the ratchet B A pinion B" is formed upon a hub B which hub is integral with the rate b et B A sprocket-chain B runs over the pinion B and at its free end has a weight B The other end of the chain is connected to a suitable drum B ann a portion of the chain is adapted to be wound upon the drum, thus drawing the weight B upwardly. ll hen the Weight descends, the chain will be unwound from the drum and will rotate the sprocket B and the ratchet B and the gear-wheel B,

being locked by the pawl B to the ratchet upon the drum B and then throwlng the B will also be rotated by the descent of weight. C, and the pinion C is also fixed upon shaft. and a pinion D.

The shaft E carries a gear- .n 'lerri t cry,

Fig. 4 is a section on the line i f of A gear-wheel C is fixed on the shat 1 The shaft D carries a gear-wheel D desired number of teeth and also a wheel of much less size, and to distinguish between these two classes the larger wheels are termed gear-wheels and the smaller ones pinions. 'lhcsc wheels are connected by sprocket-chains in the following manner: A sprocket G runs over the gear-wheel B, the pinion D, and drives the shaft D. A sproclmt-chain K runs over the pinion C and the mar-wheel E. A sprocket-chain J runs over the gear-w heel D and over the pinion F A: .jacent the upper end of the frame is a short stub-shaft 1, having a pinion L at one end and a beveled gear L at the opposing end, and a sgrochet-chain L runs over the gearwhcel t and over the pinion L.

it wiil thus be noticed that the shaft D is driven from the shaft B by the sprocketchain (-1-, and the speed of the shaft D will be tcr than that of the shaft B; that the .li} F is diivrn by the sprocket-chain J from the shaft D, and that another increase in speed is gained; that the shaft E is driven by a sprocket-chain H, which runs over the gear-wheel F and the pinion E thus fur tncr increasing the speed; that the sl it 0 is driven from the shaft E by the sprcclcrt-chain K, and that the stub-shaft I is di ivtn by the chain L from the gear-wheel C (L11 the shaft 0. It will therefore be noted that commencing with the top and going d ownwerd each shaft drivcs alternate shafts, and that coinnncncing with the bottom the ren iniitg shafts nae driven from the bottom shalt F, the speed increasing with each shaft driven. A stub-shaft L is journaled at the up of the franie at iigh angles to the shaft I and at its lower rnd carries a beveled gear L which nicshcs with the beveled gear L and at its upper end the shaft L carries a pulley L from which runs a cable or belting L, which in. turn d1 ivcs a fan M of any constructien.

twill be obvious fro m. this description and the drawirgs that by winding the chain B .1), ratchet B, that the descent of the weight,

wiich is of course regulated by the governor wheel E and a pinion E The shaft l carj ries a gear-wheel F and a inion F.

It will be understood that all of these wheels are i sprocket-wheels and are driven by means of sprocket-chains and that each shaft carries a wheel of considerable size and having any O, will drive the gear-wheel 3, and that while the s; id witccl may be driven at very slow rate of speed, the weight falling, for eX- anple, at the rate of a foot per hour, the constant increase in the rate of rotation of the shafts D, F, E, C, and I in the order named Will impart to the fan several hundred revolutions per minute, and that this speed Will be maintained for several hours or until the Weight B has fallen to its lowest lirnit.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A device of the kind described con1prising a frame, a plurality of shafts journaled therein in vertical alinenient, a gearing-Wheel fixed upon one of said shafts, a ratchet loose upon the said shaft, and having a hub portion, a pinion carried by the hub portion, a sprocket-chain running over said pinion and having a Weight at one end, a pawl carried by the gear-Wheel and adapted to engage the ratchet, and means for transn" itting in an increasing ratio the rotation of the said shaft to a fan.

2. A fan-motor comprising a plurality of shafts in vertical alinenlent, a pinion on one of the said shafts, a sprocket-chain running over said pinion, a Weight upon the free end of the said chain, said pinion being locse upon the shaft, a gear-Wheel on the said shaft, means for locking the gear-Wheel to the pinion, a pinion upon one of the other shafts, a sprocket-chain running over the gear-Wheel and the last-mentioned pinion, a stub-shaft saaaez having a bevel-gear at one end,a second stubshaft at right angles to the first, and having a beveled gear meshing With the beveled gear of the first stub-shaft, a pulley carried by the second stub-shaft, belting running over the said pulley and adapted to rotate a fan, and means for transmitting the rotation of the first-mentioned shafts to the first-mentioned stub-shafts.

3. A motor of the kind described comprising a shaft, a pinion locse upon the said shaft, a sprocket-chain running over the said pinion, a Weight connected to the chain, at one end, a drum upon which the opposite end of the chain can be Wound, a gear-Wheel fixed to said shaft, means for locking the gear- Wheel to the pinion, a fan, a plurality of shafts in vertical alinernent With the firstntentioned shaft, means for driving the said shafts an increasirn rate of speed from the firstn;entioned sh aft and 11?.62t1lSf01 transnitting the rotation of the last of the said ihafts to the fan, as and for the purpose speciled.
