WIND-ENGINE.
SPECIFICATION forming part of Letters Patent No. 261,686, dated July 25, 1882.
Application filed January '27, 1882. (Model) To all whom it may concern:
Be it known that I, FRANK G. CORNELL, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Wind Engines; and I do hereby declare that the following is a full,clear, and exact description of the same.
My invention relates to wind-engines of that class in which a sectional wheel is used in rear of the head, with an automatic regulating-governor in front of the head.
The object of my invention is to make a practical engine in which the sections of the vane shall be turned out of the wind by means of the fan in front of the wheel. There are wellknown advantages arising from the use of the sectional wheel, or wheel in which the fans are arranged in sections over a solid wheel, the principal of which are that there is less strain both upon the wheel and upon the head and working parts, and the sections are more sensitive and respond more readily to the action of the regulating vane or governor.
Heretofore attempt has been made to con nect the lever which carries the governor directly to the hinged sections of the wheel; but this plan required a long central rod projecting to the rear of the wheel and a large amount of movement in the governor lever. The central rod, extending far to the rear and weighted by the connecting-rods, would necessarily sag and give unequal movement to the sections, thereby practically rendering the engine inoperative.
My invention consists essentially in connecting the central rod to the sections by means of a series of levers.
In the accompanying drawings, Figure 1 shows a side elevation of the engine. Fig. 2 shows a central vertical section through the head and wheel. Fig. 3 shows a side elevalion of the rear face of the wheel. Fig. 4 is adetached view of a part of the arm, showing the small friction-rollers in plan.
The head A is formed of a single casting, having an ordinary hollow pivot, a, in which the pump-rod 1) works. This is provided with a hollow shaft, a, carrying an eccentric, d, having an arm,f, connected to the upper end of the pump rod. The upper end of the pumprod works in the arm,with small friction-rollers 1 1 bearing against the edge of the pump-rod. A bend in the pump-rod carries it around the shaft of the wheel. The head of the wheel is solid and provided with ordinary radial arms, 6 e, braced by a ring, g. Through thehollow shaft passes a rod, h, which is connected to the governor-lever t by means of a link, as shown at 2.
The governor-vane is shown at It and the adjustable weight at l. The central rod passes through the head of the wheel and terminates in the rear in the head m, having ears (in this case six in number) marked 3. These ears are connected by links 4 to levers 5, pivoted upon the ring of the wheel, and the levers 5 are connected by links 6 to the sections 0 of the wheel. These fans are fixed rigidly upon transverse rods 7, the ends of which bear in eyes in the radial arms of the wheel. The link-connection is toward the inner end of the sections, and any desired amount of motion may be imparted to the sections by proper proportion given to the arms of the levers. The amount of motion permitted to the central rod is enough to throw the levers from a position parallel to the head sufliciently out of the wind. With this arrangement any sudden increase of force in the wind strikes the governor -vane first, which communicates motion to the rod and levers and throws the sections, to a greater or less extent, out of the wind. As the head to which the connecting-arms are attached that operate the levers is near the hub, there is no tendency whatever to sag, and the levers and their connecting arms being properly adjusted their action is certain and uniform.
I am aware that systems of levers have been v. I claim is- 1. The combination, in a wind-engine, of the wheel mounted in rear of the head, a governorvaue in front of said head, and a rod connected In testimony whereofI have signed my name 10 to this-specification in the presence of two subscribing witnesses.
