upon the spindle 9.

To all whom it may concern:

Be it known that we, JAMES ALEXANDER MASON, ELIJAH F. MULKEY, and GEORGE W. HOUSTON, citizens of the United States, residing at Savoy, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in Power-Fans; and we do hereby declare the following to beafull, clear,

and exact description of the invention, such as to will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fans which are operated by a slowly-revolvingbarrel turned by a spring or descending weight.

I 5 This invention consists in the novel construction and combination of the parts, hereinafter fully described and claimed, whereby the fan is actuated and kept moving at a uniform velocity.

The figure in the drawing is a side view of the complete apparatus.

A is the ceiling of the building, to which the fans are hung, and a is the end wall. B is a light metal frame secured to the wall 2 5 for supporting the gearing-spindles.

G is the slowly-revolving driving-barrel, secured upon spindle c and receivingits motion from the spring D, coiled insideit, or from the descending weight E on the end of core 6,

which is wound upon the outside of the barrel; or both spring and descending weight may be used together to drive the barrel.

F is a toothed wheel secured upon spindle c and gearinginto the toothed pinion f, secured G is a toothed wheel of the same size as the wheel F, also secured upon spindle g and gearing into the toothed pinion H, secured upon the spindle h, all the said spindles being jour- 0 naled in the frame so that they may revolve freely. The gearing is so proportioned that the pinion H will make fifty revolutions to one revolution of wheel F.

I is a crank secured to one end of spindle h 5 for operating the pitman-rod J, andi is a Weight for balancing the weight of the said pitman-rod.

K is the fan-lever, provided with the blade k and with a series of holes, k, for the connection of the pitman-rod, so that the speed of the fan may be adjusted. The lever K is pivotally connected to the ceiling by the hinge L. K is a similar fan-lever connected to the lever K by the rod Z. Additional fans and levers may be added and connected together in a series, if desired. In order to render the movement of the fans uniform aregulator is secured to any one of the fan-levers. This regulator consists of the weight M, which slides up and down the lever. This weight is raised automatically by the motion of the fans as the power of the spring decreases, so that the spring then has less resistance to overcome.

N is a ratchet-wheel secured on the spindle n, which isjournaled in the frame n, secured to the ceiling. A cord, 0, is wound upon a barrel on the spindle n, and is secured to the weight M after passing over the guide-pulley o, journaled at the top of the fan-lever.

P is a pawl which is pivoted to the said 7c lever and engages with the teeth of the ratchet-wheel, and p is a retaining-catch for preventing the ratchet-wheel from slipping back. At each stroke of the fan lever the pawl P turns the ratchet-wheel one notch and winds a portion of the cord 0 upon the spindle n.

\Vhat we claim is- 1. In a power-fan, the combination of the slowly-revolving spring-barrel and the toothed gearing, the pitman -rod operated from the revolving gearing by a crank, the fan-lever connected to the pitmanrod, a weight sliding upon the fan-lever, and the ratchet mechanism for automatically raising the sliding weight, substantially as and for the purpose set forth. 5

2. In a power-fan, the combination of the slowly-revolving spring-barrel and the toothed gearing, the pitrnan -rod operated from the revolving gearing by a crank, the fan-lever connected to the pitman-rod, a weight sliding upon the fan -lever, the ratchetwheel provided with a retaining-catch, a pawl pivoted to the fan-lever and engaging with the ratchet, the guide-pulley 0, and the cord secured to the weight,-passingover the said pulleyand 95 wound upon the ratchet wheel spindle by the motion of the fan-lever, substantially as and for the purpose set forth. v

3. In a power-fan, the combination of the slowly revolving barrel, the intergearing I00 toothed wheel F and pinion f, the intergearmeeting the said fan-levers together, substaning toothed wheel G and pinion H, the crank tially as and for the purpose set forth.
