WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 264,862, dated September 26, 1882.

Application filed July 6, 1882. (No model.)

To all whom t may concern:

Be it known that I, PETER T. GOEEIELD, a citizen ofthe United States, residing at Springlield, Clarke county, Ohiozu have invented certain new and useful Improvements in Vind- Engines, of which the following is a full, clear,

and eXact description.

end to the turn-table at l.

My invention relates to an improvement in wind-engines; and it consists in arranging the turn-table so as to revolve freely on the derrick or mast, and providing it with an automatic brake operated by the wind, which will hold the wheel in the wind and prevent its walking round on the gear out of the wind.

`Figure 1 is a side elevation of the wind-engine and brake. Fig. 2 is a side elevation of the brake and gearing. Fig.3shows the ratchet and spring-pawl within the brake-wheel. Fig. 4 is a horizontal section of the brake-wheel and eccentric brake and the toothed bed-plate.

Like letters of reference indicate the same parts in different figures.

A is the top of the mast or derrick supporting the engine. Y

B is a toothed bed-plate, firmly fixed to th top ot' the derrick. C is the turntable, which `is balanced upon the bed-plate B, and revolves freely around the counter-shaft D.

On the top ot' the driving or counter shaft D, and rrnly fixed to it, is the beveled-gear wheel E, geared with the beveled-gear wheel F, fastened to the fan'sha'ft G.

H is the wind-wheel, made in any suitable form, and only partly shown in the drawings.

I is the tubular shaft, fastened at its lower Within this tubular shaft I,'and Vsupported by it, is a straight rod, J. To the upper end of this rod is attached a iiag-vane, K, made of sheet metal or other suitable material, and bent into the wind, as shown at K. To the lower end of the rod J is firmly attached an eccentric, L.

On the lower side of the turn-table, and at the end opposite the wind-wheel, is pivoted the brake-wheel M, near the eccentric brake L, and so arranged that as the rod J is turned the brake L presses against the periphery of the wheelM and acts as a brake to hold it stationary. On the lower side of this brakewhcel M are interior ratchets, (shown at O.) Below the brake-wheel M, and revolving 0n the same pivot, is a pinion, B, which is geared into the toothed bed-plate B. This pinion It is also provided with a spring'pawl, which isinserted in the brake-wheel M, and operates upon the' wind against the brakewheelM and holds it Y stationary, the pinion cannot turn from left to right, being held by the vpawl and'ratchets, and the pinion being geared in the bed-plate B, the pinion, with the entire turn-table, is prevented frorn turning from left to right. The Hag-vane is fastened to the rod J, and projects in the direction of or over the wind-wheel slightly to the leeward, and curving toward the wheel. The wind-wheel, turn-table, Sto., swing freely from ri ghtto left, when constructed as shown in the drawings of course the gearing may be inverted,) and withont a brake would swing from left to right round out of the wind; but as the wind strikes the wheel and turns the rod J and forces the eccentric brake L against the wheel M, holding it stationary. The pawl and ratchets prevent the pinion from revolving, and its teeth, meshed with the teeth of the bed-plate, prevent the turn-table from swinging any farther, holding the wheel in the wind, forcingit to revolve the Vgear-wheel F and drive-shaft D, instead of the side of the tubular shaft l and pressing "against the pin or lug T, presses the rod J around, so as to keep the brake constantly in it also strikes the concave side ot the liag-vane operation. Shouldthe wind change and strike l the Hag-vane K on the convex side, the brake will be instantly loosened and the wheel free to move round until it is again adjusted.

The dag-vane and brake may be used on a vaneiess wind-engine or in connection with a vane.

To secure greater friction, the edge of the brake may be made convex and the' periphery of the brake-wheel correspondingly concave or curved with leather; but any suitable substance or construction may be used.

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

l. In a wind-engine having` a flag-vane and rotating pump-rod, the combination, with the wind-wheelshaft and the rotating pump-rod, with connecting` mechanism, of a curved llagvane provided with a brake at its lower end, whereby the wheel is held in the wind and prevented from walking around on its mast or derrick, substantially as described.

2. In a wind-engine, the toothed bed-plate B, in combination with the pinion R and-brakewheel M, arranged as and for the purpose specied.

3. The brake-wheel M and pinion It, so con- PETER T. COFFIELD.
