JONAS H. ALDRICH, OF BUTLER, INDIANA.
WINDMILL.
SPECIFICATION forming part of Letters Patent No. 402,552, dated May *7, 1889.
Application filed March 24., 1888. Serial No. 268,449. (No model.) W
To all whom it may concern.-
Be it known that I, JONAS I-I. ALDRICH, a citizen of the United States, and a resident of Butler, in the county of De Kalb and State of Indiana, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
My invention relates to windmills of that character in'which the wind-wheel is thrown from the wind by means of a governor-rod having a swiveled connection with the vanecasting.
The object of the invention is to provide a spring-brake against which the pitman-wheel is forced when the wheel is being thrown out of the wind, and to which a final pressure of sufficient power is given to stop the revolution of the wheel by the inner end of the g overnor-rod.
In the drawings, Figure I is a perspective view of a sufficient portion of the mill to illustrate the operative parts when assembled. Fig. 2 is an elevation of the cap with the wheel and vane omitted. Fig. 3 is a side, and
' Fig. 4 is a sectional, view of the main shaft and bearings.
A designates the derrick; B, the cap into which the vane-casting C is journaled, vanecasting 0 being provided with a vane, D, supported by a rod, E, preferably formed of ordinary gas-pipe and having a squared end which is inserted into a squared perforation in the vane-casting and held in place by a set-screw, E.
F designates the journal-box in which the wheel-axle F revolves, and is composed of lower section, F, cast integral with the upper section of the pitman-guide and upper section, F secured to the lower section by bolts 0.
G designates the wind-wheel attached to journal F in the usual manner, pitman-wheel M being attached to the opposite end of journal F and connected with pitman Nby rod N.
wind and the, pitman-wheel against a springbrake, L, connected to the vane-casting and extending upwardly in an inclined direction in a position to be actuated by the inner end of arm I, to bring sufficient friction upon the wheel to stop the revolution thereof when the wind-wheel shall have been entirely turned from the wind.
K designates the bearing for the lower section of the vane-castihg journaled in cap B and extending downwardly. Bearing K has the usual cylindrical opening, into which the upper portion of the pitman-guide is journaled and held from vertical'movement by washer K and set-screw K.
N designates the pitman reciprocated through the medium of pitman-wheel M and rod N, connected to the wheel and pitman by means of bolts, which allow an easy movement of the parts. Rod N is so arranged with reference to wheel M and pitman N that the vertical li-ft upon the pitman shall be when rod N is in a parallel relation with the pitman, thereby giving the maximum power of the wind-wheel in raising the pitman and the rod attached thereto. 7
By the use of the spring-brake there is no sudden frictional engagement with the wheel. The action of the brake is gradual, thereby having no tendency to torsional strain upon the axle by reason of too sudden stop.
Having described my invention, what I claim, and desire to secure by Letters Patent, 15-- In a windmill, a spring-brake attached to the vane-casting and projecting in the path of travel of the pitman-wheel and governorrod, as and for the purpose set forth.
In testimony that I claim the foregoing as my own I hereto affix mysignature in presence of two witnesses.
JONAS I-I. ALDRICH.
