WIND-MOTOR.

SPECIFICATION forming part of Letters Patent No. 464,607, dated December 8, 1891.

I Application filed March 6, 1890- Serial No. 842,932. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. BROWN, a citizen of the United States of America, residing at Tina, in the county of Carroll and State of Missouri, have invented certain new and useful Improvements in \Vind-Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improved system of wind-motors. The invention consists of the new combination of parts hereinafter more fully specified.

The invention is illustrated in the accompanying drawings, Wherein Figure 1 is a side elevation showing the improved construction of motor-wheel, the tailvane for keeping the motor-wheel in the wind, the combination of parts to guard against shock and prevent strain in violent or chopping winds, the manner of transmitting power, the turn-table adapted automatically to turn by the action of the wind, the automatic brake, and the pyramidal frame, upon which all the parts rest. Fig. 2 is afront end view of the motor-wheel, illustrating the position and shape of the blades and, further, showing the construction of the motor-wheel and of the parts to prevent shock. Fig. 3 is a somewhat exaggerated sectional view of the automatic adjustable bearing or boxes in which the motorshaft runs, the eccentric upon the motor-shaft by which the pump is run, the sleeve and clutch to engage the eccentric, and the lever and its operation, by which the eccentric is automatically disengaged and the pump is stopped. Fig. 4 is a plan view of the motorwheel with blades removed, of the brake and its connections, and the manner in which it is automatically operated, &c.

Figs. 1 and 2 illustrate the form and shape of the blades of my improved wind-motor. From these figures it will be seen that the whole apparatus rests upon and is fastened into the circular turn-table O, which is free to turn automatically by theaction of the wind upon the circular platform B, which in turn is fastened and supported upon the pyramidal frame A A, the motor-wheel being kept in the wind by means of the directing tail-vane D.

I will first describe the construction of the motor-wheel with its siX nearly curvilinear blades G. Each blade considered in itself forms the arc of about one-third part of a circle. All blades begin in front at a common center D and extend in curved radii to the common periphery D each blade being riveted to and held in place by and upon the arms D of the ring E, and to and upon the curved spokes D radiating from the hub E. Said spokes D are straight from the hub E to the point of their contact F with side blades, being curved to accommodate the curve of the blades and extending to the periphery D Each blade is braced and connected by the stay D extending from D to the point G is the motor-shaft passing through the hub E and through the ring E and carrying the motor-wheel, said motor-shaft being secured in the boxes G and G The principal part of the motor-wheel rests upon the hub E, and the ring E acts in the nature of a guide to keep the center of the motor-wheel in a line with the motor-shaft, both motorwheel and motor-shaft revolving together, the motor-shaft being the common center. Said ring E and hub E are held in the same relative position laterally to each other upon the motor-shaft by means of the attachment of the blades G to the arms D and the spokes D The motor-wheel has a slight longitudinal and also a limited rotary motion upon the motor-shaft. This rotary motion is limited to the distance between the contiguous spokes D D is a cross-bar securely fasten-ed at right angles to and upon the motor-shaft and can only revolve as the motor-shaft revolves. From either end of said cross-bar D the spiral springs D are attached, their opposite ends being also attached to the spokes D H H are disks upon and through which the motor-shaft passes, said disks being joined and rigidly connected together by lateral rods H one of said rods passing over-and one under or between spokes D and in like manner under and over the crossbar D Said disks have a slight longitudinal and also a slight rotary motion upon the motor-shaft. The combination of the spring D with the cross-bar D, the spokes D and the motorshaft G provides a yielding rotary motion, which effectually prevents shock to the motor-wheel. The disks II and ll, with said lateral rods 11*, form part of an automatic brake, about to be explained, to operate upon the motor-wheel.

H is a brake-shoe adapted to engage by pressure the disk II whenever the lever H is carried to the right. The disk II being pushed to the left causes the disk H to press theringE, and the rods I-l between the spokes D and between the arms D form a combination which acts directly upon the motor-wheel to check or stop it. The lever H is connected by the chain H to the projecting arm H from the tail-vane D. Now it is obvious that tlie'tailvane D, being carried to the right, the proj ecting arm 11 will engage the chain H which in turn engages thelever II, which engages the rubber H which engages the disk II, and so on, in the combination already described, which operates upon the motor-wheel.

I is a governor-weight operating upon a curved arm to'keep the tail-vane D in line with the niot0r'shaftthat is, to keep the motor-wheel in the wind when said wheel is in action. The tail-vane D is attached to the uprightframes K by means of the hooks K and K and the projecting arms G and G in such a manner as to be free to turn to the right whenever the weight I is raised.

G is an arm projecting at right angles to and from between the frames K having a hole through the projecting end adapted to receive the hook from the upper arm of the tail-vane D and being provided with lugs upon either edge to prevent its being pulled from between said frames by the weight of said tail-vane. Said arm is curved upward from the said lugs, so that its inner end passes upward between the upper sides of the frames K and when said tail-vane is hooked in position, as shown in the drawings, said lugs are pressed upward into the front angle of said frames. Said arm G has a corresponding arm G which is riveted to the edge of the turntable C, and is provided with a hole through the projecting end to receive the lower hook of the arm from said tail-vane D. The tail-vane D is held in its normal position by means of the curved arm of the governor-weight I and can only turn to the left from said normal position-that is to say, it has a yielding motion to the left of about ninety degrees from its normal position, yielding to sudden side pressure of the wind. A violent or chopping wind striking said tail-vane upon the side will automatically raise the weight by pushing the tail-vane to the left, and the movement of the tail-vane to the left, as already seen, automatically applies the brake which operates upon the motor-wheel, as described. The weight I may also be'raised at will from the ground and the motor stopped by means of an appliance not shown in the drawings.

I will now describe the boxes G2 and G in which the motor-shaft is journaled. These boxes are adapted to be held in place between the parallel sides of the upright frames K and rest upon the springs K and K The box G has a slight movement between the frames K, to accommodate the movement of the motor-shaft whenever the box G3 is from any cause forced downward. The end of the motor-shaft maybe forced or pulled down by the pump or otherwise, in which case the pump will be automatically disconnected by means of the lever engaging the clutch K and the pump will remain disconnectedas long as the end of the motor-shaft remains below normal.

L is an angle-lever having two arms, one of which is adapted to engage the sleeve or clutch K upon the motor-shaft, by means of which the pump may be automatically disconnected. One arm of L is placed beneath the box G and whenever said box is forced down the opposite arm of L engages the sleeve or clutch K and disengages the pump. The pump is run by an eccentric upon the shaft of the motor-wheel, and the clutch IQ is adapted to disengage the pump from said eccentric.

M is a hollow shaft having bevel cog-wheel at top and bottom with engaging-wheel on motor-shaft, and at bottom showing means of transmitting power.

4 N is a pump-rod which works inside of the hollow shaft M.

O is a lever adapted to connect or disconnect the power by raising or lowering the hollow shaft M.

P illustrates means for distributing power.

The object and purpose and the operatron of the several parts of the mechanism hereinbefore described and set forth, both in detail and in combination, it is believed will be readily understood from the description already given.
