JOHN C. ORMISTON, OF GENESEO, AND EDMUND S. SEGER, OF ERIE, ILL.
IMPROVEMENT IN WINDMILLS.
Specification forming part of Letters Patent lNo. 168,917, dated October 19, 1875 application filed February 19, 1874.
To all whom it may concern:
Be it known that we, JOHN C. OEMTs'roN, of Geneseo, in the county of Henry and State of Illinois, and EDMUND S. SEGER, of.Erie, in the countyof Whitesides and State of Illinois,
have invented certain Improvements in Windmills, of which the following is a specification.:
The nature of ourinvention consists in certain new and novel construction, to be hereinafter more fully described; also, in combining' in the construction of the parts of the mill a large amount of wood-Work; in equally spacing' the sails ofthe windmill; and in providing a double pivot-box, which holds out the cross-head by means of a, pivot, and upon which the sails are set, all ot' which will be more fully understood by referring to the letters of reference upon the accompanying sheets of drawing, in which- Figure 1 is a side elevation of our windmill. Fig.r2 is a plan of the top 0f the windmill. mechanism. Fig. 4 is a side view of the mill, having some of the sails removed to show the opening and closing mechanism. Fig. 5 is a part rear view ot' the sails upon the wheel. Fig. 6 is an end view oflpivot-box; Fig. 7, side view of Fig. 6; Fig.l 8, front view ot' Fig. 6.
ln all the same letters refer to the same parts.
'lhe iron crank-axle B rests upon bearings upon the turning or revolving top, and is held in position by the tubular bearing A. This upper part carries the crank-axle and the sails, with the arrow end to keep the Wheel of ofthe mill in the wind. Upon the front of the crank-shaft B and attached thereto is the spider-boss F, having theprojections f. These are sunk into and attached to the wooden spokes E, which radiate therefrom. These spokes E are held out in their position by a simple brace or tie, H, and bolt h. Near to the outer end of these said spokes E, upon their outside or outward side, there is let in or sunk in the double pivot-box e, and work- Fig. 3 is the arrow ot' the balancing' ing in this said box e are the pivots g, attached to the joist cross-heads G, which carry the sails I. The cross-heads G are merelyoblong pieces of wood, having cuts made in the front tace to receive the sails, and. each out represents and gives to the sail the angle it is intended for it to present to the wind, and by merely making the overlapping piece g formed upon the joist cross-heads G the sails are enabled, when thrown to the wind, to be equally spaced; also, this construction permits the cross-heads being light and inexpensive. To revolve the cross-head so as to take the sails in from the wind, or to give them to the wind, there is bolted at or nea-r themiddle of these joist cross-heads alug, d, and this lug is connected by a rod with the opening and closing lug D upon the crank-axle. There is also provided, underneath the tubular bearing A, a steadying-ring with a means of holding the connecting-rod, and this guide is attached by means of a bolted point tothe supporting-post P of the windmill. This guide is made by placing two plates together l and riveting them in that position, each having a shoulder which is made to t the ring, and any direction taken by the wheel of the mill, due to the action of the wind, the guide, as before mentioned, will revolve with the connecting-rod.
Having thusdescribed the construction and .operation of our invention, what we desire to secure by Letters Patent ofthe United States is as follows:
In a balanced revolving windmill, the combination of the crank-axle B with the boss F,
having arms f, the spokes E, having let therein the double pivot-box e, and held by braces H and bolts, with the joist cross-head G, having thevsails I revolved and operated by the lug d, connection d', and lug ou crank B, all operating substantially as herein set forth.
JOHN C. ORMISTON. EDMUND S. SEGEB.. Witnesses:
ANDREW J. OsBoENE, LEVI WEIGHT.
