Wind-Mills.
Patented Septemberl, 1873.
NITED STATES PATENT OFFICE.
EPHRAIM A. ATWOOD AND HARRY H. BODWELL, OF SAN FRANCISCO, GAL.
IMPROVEMENT lN WINDMILLS.
Specification forming part of Letters Patent No. 142,885, dated September 16, 1873; application filed September 3, 1873. Y
To all whom it may conoerm Be it known that we, EPERAIM A. ATwooD and HARRY H. BODWELL, of San Francisco city and county, State of California, have invented an Improved Windmill; and we do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use our said invention or improvement without further invention or experiment.
Our invention relates to certain improvements in Windmills; and it consists, rst, in a novel mechanism by which the hinged tail or rudder of the mill is turned from a position in line with or parallel to the axis of the windwheel to any desired angle with this line up to a right angle, and at the same time locked in such position Without any other special locking device. This enables us to throwr the wheel into or out ofthe wind to a greater or less degree, as required. The turning and locking device for the tail is operated by a cord passing over two vertical pulleys, one upon the shaft of the worm or screw, and the other conveniently situated near the ground.
Referrin g to the accompanying drawings for a more complete explanation of our invention, Figure l is a perspective view of our mill. Fig. 2 is a sectional elevation. Fig. 3 is a plan or top View.
A is the supporting-frame of a windmill, having the upper platform B, through which the hollow post G passes and turns about its axis, being supported by a step on the platform or cross-beams at D. The axis or shaft E of the Wind-Wheel turns in boxes at the top of this post C, the crank standing above the opening in the post, through which the pumprod passes. At the side of the post opposite to the wind-wheel the shoe which supports the inner end of the tail or rudder is hinged. This shoe is ordinarily of cast-iron, and has a trough or socket in its horizontal portion F, into which the wooden beam Gr of the tail is secured. A vertical arm or part of the shoe H extends downward beside the post O, and` ment will also be turned gradually around,
and thus swing the shoe and the tail or rudder.
It will also be seen that this construction makes a complete lock for the rudder, as the worm will hold the segment at any point where it may be stopped.
In order to operate this mechanism more conveniently and from the ground a pulley, M, is secured to the end of the shaft N of the worm, one edge of the pulley turning through a slot through the post G, so that the cord O will pass down inside the post. The other side of the cord also enters the post through an opening, P, above the platform B, so that the two parts of .the cord will pass down inside of the post and not interfere with lits turning about upon its axis as the wind-wheel changes its position. A friction pulley or idler serves to relieve the rope where it passes through the hole P. Below the step on which the post C is supported is another vertical grooved pulley, R, around which the rope O passes, this pulley being hung in a block or frame, S, so as to be conveniently near to the ground. A guide-rod, T, suitably placed, prevents the pulley from turning around and twisting the rope.
In order to compensate for the lengthening and contracting of the rope O a spring, U, or a weight is made to give it the proper tension.
By this construction we are enabled to greatly cheapen and simplify our mill, as by the use of the worm-gear the tail can be easily turned, and at the same time locked in any position.
R may be a roller around which the rope O makes several turns, the ends being secured to it.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. 'lhe worm L and thesegment K, for the purpose of turning the tail to any position and lockingit, substantially as herein described.
2. In combination with the Worm L and the segment K, the vertical pulleys M and R, and the rope O, for the purpose of operating the rudder from the ground, substantially as herein described.
3. In combination with the pulle5r R eindredjusting-spring U, the guide-rod T, to prevent twisting, substantially as herein described.
In Witness whereof We hereunto set our hands and seals.
