IMPROVEMENT IN HORIZONTAL WIND-WHEELS,

Specication forming part of Letters Patent No. 168,608, dated October 11, 1875; application led August 31, 1875.

To all whom it may concern i Be it known that I, FOGHT BURT, ot' Van Wert, Van Wert county, Ohio, have invented an Improvement in Horizontal Wind-Vheels; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings mak' ing a part of this specification, in which like letters of reference refer to like parts, and in Which- Figure 1 represents au elevation or vertical section on line a a, Fig. 2 5 Fig. 2, a horizontal section on line b b, Fig. 1. 4

This is an improvement in horizontal windmills inclosed in adjustable slats or shutters; and the rst part of the improvement consists in the use of trough-shaped vanes, which present a more effective surface to the wind; second, in the mode of hanging and operating the shutters which incluse the wheel; third, in the mechanism for cutting off high winds, automatically applied to the shutters; fourth, in the automatic closing ofthe shutters by action of water from the overow from the full tank falling into a bucket. This is the old horizontal wind-wheel inclosed within a circle of vertical shutters to admit or to cut olil the wind. The radial vanes of the windwheel are trough-shaped, presenting the hollow side to the wind. The slats or shutters are pivoted at their middle by hinges, assisted by springs or hinges, which are at once springs and pivots, acting to keep the shutters in their normal position, i. c., open; and these are all closed simultaneously by the construction of an encircling wire,which passes through a staple or eye projecting from the outer edge ot' each shutter. One end of said wire is iixed to one of the four corner-posts, or other point, while the other end, after making the circuit of the shutters, is iixed in the channel in the periphery of a wheel or pulley attached Ato another post, and governed by a horizontal governing wind-wheel above or on top of the machine by means of a lever and cord attached to a lever on said pulley, which tightens the wire and shuts oi' the wind from the wheel. This pulley and lever is also operated to close the slatspin the same way by'means of a cord, which passes up from the said lever over a second pulley, and attached beneath an overl flow-spout at the water-tank to a bucket, the

filling of which bears down the cord and raises the'lever, which noWcloses theshutters.

In the drawings, which represent oneof the forms in which I construct my wind-wheel, A A` represent a rectangular frame, which incloses the wind-wheel C and its shut-ters E E; B, a horizontal platform supporting the wheel; C, the wheel, having a vertical axle or shaft, l, pivoted above and below in the frame A A, and ending below the platform B in a crank, c'. The wheel has several radial arms, b, which carry `the trough-shaped vanes a, so made to give greater impetus to the wheel.v D D represent circular horizontal rings above and below the shutters E, to which either end of their respective standards g g, &c., are attached. vThese rings are attached, respectively, to the platform B and to the frame above. E E are the vertical adjustable shutters which encircle the wheel C, by which the supply of wind is regulated. These are each attached.

to their respective standards g, along a centralrib on said shutters, by means of a tlat piece of rubber, h, or other elastic material set in mortises in said shutters and standards, in such a manner as to hold the shutters elastically to the inner face of their respective standards, which latter have their said faces inclined tangentially to the wheel, or, rather, in the direction ofthe normal or open position of the shutters. Any other hinge which will have the same effect may be used in conjunortion with an auxiliary spring to keep the shutters open. From the outer edge of each shutter projects au eye or staple, each of which is' threaded by the encircling wire F, which is fixed at one end to one ofthe cornerposts A, and, after making the circuit of the shutters, the other end is extended to the channel in the pulley G and fixed therein. This pulley or grooved wheel G is pivoted vertically to one ofthe corner-posts, opposite the post in which the other end of the Wire is fixed. To the outer face of this pulley G is attached a lever, H, to the end of which the cord il ofthe lever I on the top of the machine is attached. This lever I is a horizontal one, and is connected at its other end to the axle of a horizontal governing-wheel, K, above the wind-Wheel by la cord or wire, q. A second cord or chain, k,

passes from the end of said lever H over a small pulley, p, above the pulley Gr, along the groove of the latter, down to the bucket, whose mouth is below the end of the tank overoW-spout, which, on lling, raises the lever and closes the shutters. A Weight, o, at the same end of the lever helps to enlarge the circle of the Wire F, and relax it when the Wind is light, and keep the shutters open. K, the governing-Wheel, to regulate the Wind upon the Wheel, also inclosed in shutters L; but the latter are Xed, and arranged tangentially to the Wheel Within. This Wheel K has a Wire or cord, q, attached to its axle, which runs to the lever I, before described, and is adj ust-able atany point o'the'am of said lever to obtain a proper Working tension upon the Wire F in closin g the shutters E in a high Wind. M, the walking or piston beam to work the pump or pumps, the vertical arm r of which beam is connected to the crank e of the shaft Z of the Wheel C by means of the rod f.

The operation of this wind-Wheel is as follows: In an ordinary Wind the Weight o of the lever H keeps the Wire F extended or from constricting the shutters E E, &c. When the Wind is too strong the governor-Wheel K winds up the cord q, which causes the lever I to tighten the Wire F, by rotating the pulley G and closing. the shutters E more or less, preprovided with a central rib, the elastic hinges' h h, or equivalents, and the eyes or staples m m, arranged and operating as described.

2. The combination, with the eyes m m and shutters E E, 85e., of the constricting-Wire F,

arranged and operatingV substantially Yaside- Y Y Y scribed.

3. The combination, With the Wire F, ofthe pulley G, lever H, provided With Weight o, and cord k, substantially as described.

4. The combination, With the lever H, of the cord i, lever I, cord q, and governing-Wheel K, provided with shutters L. g

In testimony that I claim the foregoing windmill improvement I have hereunto set my hand this 1st day of August, A. D. 1875.
