UNITED STATES CHARLES H. EGGLESTON AND WILLIAM M. PHELIS, OF MARSHALL,
MICHIGAN, ASSIGNORS OF ONE-HALF THEIR RIGHT TO C. S. CRANE OF SAME PLACE.
IMPROVEMENT IN WINDNHLLS.
Specification forming part of Letters Patent No. [62,636, dated April 27, 1875; application filed October 5, 1874.
To all whom it may concern Be it known that we, CHA s. H. EGeLEsToN and WILLIAM M. PHELPs, both of the city of Marshall, State of Michigan, have invented a new and Improved I/Vindmill, of which the following is a full and accurate description, reference being had to the accompanying drawings.
Figure l, Sheet No. 1, is a side view. Fig. 2, Sheet No. l, is an enlarged isometrical View, showing a portion of the main shaft, the sliding collar, and its connection with one of the sections of the wheel-wings. Fig. 3, Sheet No.2, is a rear view of the wheel.
In Fig. l the full lines represent the wheel in the wind in working order, and the dotted lines show the position of the parts when thrown out ofthe wind, and the wheel at rest.
The wheel A A is made up of the ordinary small rings set in ribs T, Figs. 1, 2, and 3, but arranged in sections. These sections are hinged radially upon the arms J ot the wheel by means of the hinges l l, Figs. 1 and 2, attached to the ribs T, so as to allow them to swing round the arms J, and present their edges to the wind when the wheel is at rest. An arm, Q, Fig. 2, is attached to each section, to which is hinged, at m, a link, k, which is also hinged to the sliding collar K. The collar K moves freely upon the shaft L, but is held fronrrevolving upon the shaft by the key s fitting loosely into a corresponding groove in the collar. This collar has a groove, t', out in its outer surface near its rear end, in which a yoke upon the end of the connectingrod G works loosely. The rod G is hinged at g to the standard D of the governing-vane B.
The standard D is hinged at e, so as to vibrate in a vertical plane, parallel to the axis ofthe wheel. The vane B is hinged at n, to vibratein the same plane. A short bracket, b, is attached rigidly to the back of the vane B. To this bracket is hinged, at o, a tilting rod, C, which is also hinged at its lower end at a point in front ot the standard D. The lower hinge of C is shown at d, Fig. 3. The armt and weight F are rigidly connected to the standard D, tending always to hold it in an upright position. A crank, a, is formed in the main shaft L, to which a pitman, for working a pump, may be attached. H H are tle bearings of the main shaft. ff are pulleys, over which the rope r are carried. N is the main pivot, on which the whole turns. It is hollow, to admit the passage of a pitman and the rope r. O is the vane for holding the wheel always facing the wind.
The operation ot' this wheel is as follows, viz: The weight F is so adjusted as to hold the standard D and its vane B upright against a breeze of given force. Vhen the force ot the wind exceeds this limit, the vane B, and standardD, and rod C are oscillated backward, carrying with them the rod G and sliding eollar K, and, by means of the links It, causing' the sections A to revolve upon their hinges, and assume a position approximating more or less to that indicated by the dotted lines A A. The tilting rod C and its connections are so proportioned that when the Wing-seetions ot the wheel have been revolved so as to present the edges of the wings to the wind the vane B shall assume a horizontal position.
In order to stop the wheel, it is'only necessary to pull down upon the rope r attached to the arm t, thus throwing the various parts of the wheel into the position indicated by the dotted lines, when all the wings and vanes will present only their edges to the wind, enablin g it to sustain, without any serious strain, a severe storm.
Practical experience has demonstrated that it is prime importance in a windmill that less force should be required to operate the governing device when it iirst begins to act than when it approaches its limit ot action, so that it may act gradually, and never allow the mill to be thrown suddenly out of the wind in gust-y weather, as is the ease with most devices. VVe secure this gradual movement by means of the peculiar arrangement of the various parts ot' our device. As the vane B moves backward under the pressure of the wind the tilting rod C causes the vane B to tilt over more and more, but evenly, and just in proportion to the increasing force of the wind, and presenting less and less surface to 2. The combination of the vane B, tilting rod C, and Weighted hin ged standard D, with the connecting-rod Gr, sliding collar K, links 7c, arms Q, and sections A, when constructed and operated in the manner and for the purpose substantially as shown and specified.
