SPECIFICATION fomnng part of Letters Patent No. 686,200, dated November 5, 1901.

Application filed April 25, 1901. Serial No. 57,683. (No model.)

` tralia, have. inventeda certain new and useful Improved Wind-Motor, of which the following is a specification.

This invention relates to an improved windmotor from which more power can be obtained than from those hitherto in use and which can be constructed at much less cost.

According to this invention a horizontal shaft revolves in bearings in a rotatable U standard or frame on the top of the tower. The said shaft carries sails or vanes of peculiar construction in that they are composed of two semicircnlar metal sheets (preferably of plain or corrugated galvanized iron orsteel) secured across the shaft at an angle of about forty-five degrees and at right angles to each other. The sails are braced together and `form an ellipse when viewed from eitherside or from either end. From the main shaft is driven a counter-shaft, having bearings in the said U -standard for reciprocating the pitman-rod. y

In order that the invention may be clearly understood, reference will now be made to the accompanying drawings, in which-- Figure l is a front and Fig. 2 a side elevation, and Fig. 3 a plan, illustrating the` improved wind-motor, while Fig. 4 is a plan of one of the sails. Fig. 5 is a detail in elevation, on an enlarged scale, showing the manner of securing the sails to the ties.

Portions of some of the figures have been shown broken away for the sake of clearness.

The same reference -letters indicate the same or corresponding parts.

A is a U-shaped standard or frame carrying the horizontal shaft A' in the bearings A2.

B B are the semicircular sails or vanes secured across the shaft at an angle of about forty-ve degrees, each sail Vbeing at right angles to the other.

C C' are sprocket-wheels on the shaft A and countenshaft D, respectively, geared together by the chain C2. The speed of the countershaft may be varied by changing the size of the sprocket-wheels.

D' D' are bearings for the shaft D.

D2 is a crank-disk carrying the arm or crank pin D3 for reciprocating the pitman-rod E.

F is a cast-iron sleeve-pipe, having ballbearings at F' (not shown) between its flange and that of the pivot of the U-frame.

G is a Babbitt or other suitable metal bearing, and H a metal cap holding the top of the tower rigidly together.

J is the guiding and regulating vane.

K K are lubricating-cups.

L L are ties bracing the sails together.

The somicircular vanes or sails B have rounded notches, as B', centrally of their straight edges to receive the shaft A' substantially at the middle of the latter, While the opposite ends of the vanes are fastened by screws, as L', to the outer ends of the oppo sitelydisposed arms-of the ties L, the hubs' of which are fastened to said shaft.

In operation the wind strikes the surface of the sails B, and the shaft A being rotated drives through the gear-wheels C C' the counter-shaft D', by means of which the pitmanrod E is reciprocated. The sails are kept to the wind by the U-frame being pivoted off the center, as shown clearly in Figs. l and 3.

It will be understood that any number of sails may be employed, this being simply a matter of choice, and that alterations may be made in the details without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, ism-- l. In a wind-motor, a horizontal shaft and a pair of semicircular sails secured at their inner straight edges directly to said shaft and substantially midway of the length of such edges, said sails being set approximately at right angles to each other. I

2. In a wind-motor, a horizontal shaft and a pair of semicircular sails secured at their inner straight edges directly to said shaft and substantially midway of the length of such edges, said sails being set approximately at right angles to each other combined with a rotary U-shaped standard the branches of which support the opposite ends of said shaft.

3. In a wind-motor, a horizontal shaft and a pair of semicircular sails secured at their inner straight edges directly to said shaft and substantially midway of the length of such Io edges, said sails being set approximately at right angles to each other combined with a rotary U-shaped standard the branches of which support the opposite ends of said shaft a second shaft also supported by said standard and driving connections between said 15 shafts.
