UNITED STATES PATENT FFTCEQ WINDMILL.-

SPECIFICATION forming art of Letters Patent No. 609,457, dated August 23, 1898. Application filed May 26, 1897. Serial No. 638,197. (No model.)

To all whom, it may concern: I

Be it known that 1, LA VERNE W. Novas, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Ill i-' nois, have invented a certain new and useful Improvement in WVindmills, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a windmill.

My object is to provide an improved construction of vane-support and to provide a simple and effective furling' device and brake for bringing the wheel to rest. The tail-bone is formed straightbetween the pivot and the vane, and in order that it may not interfere with the drivingtrain when out of the wind the pivot for the tail-bone is provided upon an arm or bracket extending outward from the frame to support the tail-bone in position beyond the path of travel of the driving-gear. The end of the tail-bone is resiliently connected with the furl-leverby means of a coiledspring, and the vane is locked out of the wind by means of a locking-rod. The brake com prises a brake-disk adapted to engage the rim of the wheel-spider, the brake-disk being threaded upon a rotatable ring, which in turn is threaded upon a stationary partof the frame, and the ring is rotated to advance and retract the brake-disk by means of a weight which is raised and lowered by the furl-lever, thus throwing on and off the brake as the furl-lever is moved to throw the wheel out of and into the wind.

Referring to the accompanying drawings, Figure 1 is an end view of the mill in elevation. Fig. 2 is a side view thereof. Fig. 3 is a detail view of the brake and furling-lever. Fig. 4 is a plan view of the mill. Fig. 5 is a detached view of the brake-disk. Fig. 6 is a sectional view thereof on line 6 6, Fig. 5. Fig. 7 is a detached view of the brake-ring. Fig. 8 is a sectional view thereof on line 8 8, Fig. 7 Fig. 9 is a sectional view of the shaft-bearing. Fig. 10 is a sectional view showing the parts of the brake assembled.

Like letters refer to like parts in the several figures.

Thehub or spider 'c of the wind-wheel is carried on a shaft or axle b, journaled in the bearing-sleeve a. Upon the opposite end of the shaft is carried the pinion b, which meshes with the gear-wheel b journaled upon the shaft or stud b carried on the frame of the machine. The end of the pitman-rod c is journaled to a crank-pin on the wheel 6 and is journaled at theopposite end to a pin on the link 0, having a bifurcated end 0 c journaled upon the rod or; shaft 0 carried in bearing o To the pin on the link 0 is also journaled the end of the pump-rod 0 As the main shaft rotates motion is transmitted to the gear-wheel b and from thence through the pitman-rod to the link a, causing the same to vibrate to reciprocate the pump-rod.

Upon the standard or frame is provided an extending armor bracket d, to the end of which the upper member or tail-bone e of the vane is pivoted, while the lower member or tail-bone brace d is pivoted upon an arm or bracket d',likewise extending from the frame; The lower pivot is more remote from the frame thanthe upper pivot, so that the vane when in the wind is elevated and will return to the position'out of the wind by its own weight when released. Upon the frame is carried a projecting arm' or stop 01 which limits the inward movement of the vane when swinging out of the wind. The lengths of the arms d d and of thestop d are such that when the vane is out of the wind and lies parallel with thewheel the bones of the vane rest beyond and out of the path of travel of the driving train or gear of the wheel. By this construction the tail-bone may be made perfectly straight between the pivot and the vane, and when out of the wind the tail-bone will not interfere with the driving-train.

. through the barrel of the frame alongside the pump-rod. To the end of the tail-bone is attached a rod h, which extends through the interior of the coiled spring f and rests against the inner face of the brake-disk when the wheel is out of the wind, the end of the rod resting in engagement with one of the vertical ridges 7a 70 upon the said disk. The end of the rod is held against the disk by engagement with the lug 72, on the lower arm of the furl-lever, which limits the outward movement of the rod and presses the same against the face of the disk.

When it is desired to furl the mill, the furling-rod is pulled to rotate the furl-lever and move the arm g thereof to the right, Figs. 1 and 4, thus moving the end of the coiled spring between the brake-disk and the end of the brake-rod h to disengage the rod from the ridges on the brake-disk and permit the continued movement of the furl-lever to draw the wheel into the wind. When in the wind, the parts occupy the positions shown in dotted lines in Figs. 1 and at. In throwing the mill out of the wind the furling-rod is released and the vane by its weight swings inward and thereby through the coiled spring draws the arm g of the furl-lever to the left and carries the end of the brake-rod h into engagement with the brake-disk, thus locking the vane in position and the wheel out of the wind.

I will now describe the brake for checking the rotation of the wheel when thrown out of the wind.

Upon the bearing-sleeve a is provided a series of screw-threads a M, with which engage threads on the interior of brake-ring Z, carrying upon the exterior threads Z Z, which engage corresponding threads in the bore of the brake-disk 7c. The periphery of the brakedisk is beveled and engages a correspondingly beveled flange or rim on the spider a of the wind-wheel, so that when the brake-disk is moved into engagement with the rim of the spider the latter is brought to rest. The brake-disk It carries a downwardly-extending arm having a bifurcated end which straddles the bearing-sleeve a to prevent the rotation of the disk. Upon the brake-ring Z is provided a lug Z carrying a socket in which is clamped, by means of set-screw Z the end of rod m, carrying upon the end a weight on. The rod m rests upon and is supported by an arm or lug m on the arm g of the furl-lever, and when the wheel is in the wind and the furl-lever is in the position shown in dotted lines in Fig. l the rod is elevated, thus rotating the brake-ring Z to move the same away from the wind-wheel, due to the screw-threads on the ring engaging with those on the bearing-sleeve. The rotation of the ring within the brake-disk in turn retracts the disk, due to the engagement of the threads on the ring and disk. The brake-disk is thus maintained out of engagement with the rim of the spider and the wind-wheel is free to rotate. When the wheel is thrown out of the wind, the furllever assumes the position shown in full lines in Figs. 1 and 4, thus lowering the rod m and rotating the brake-ring to advance the same toward the spider, and thereby advancing the brakedisk into engagement with the rim of spider to brake the wheel and bring the same to rest.
