SPECIFICATION formingpart of Letters Patent No. 226,036, dated March 30, 1880.

Application filed January 26, 1880.

To all whom it may concern:

Be it known that I, Oason GoLvIN, of Schoolcraft, in the county of Kalamazoo, and in the State of Michigan, haveinvented certain new and useful Improvements in WVindmills; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a windmill, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation of my improved windmill. Fig. 2 is a side view of the vane and upper part of the mill. Fig. 3 is a plan view of the turn-table and the devices connected therewith. Fig. 4 is a central vertical section of the same. Fig. 5 is a vertical section of the upper end of the mill. Fig. 6 is a plan view of the center of the base upon which the turn-table rotates.

A represents a circular rim, provided with interior braces or crossbars, B B, and placed over and firmly secured to the top of the derrick of a windmill. In the center, between the interior braces or cross-bars, B, is formed a cup, 0, through the bottom of which projects ahollow center-pin or journal, D, of the turn-table.

The turn-table consists of a circular rim, F, with radial braces E, and from the center projects downward the hollow center-pin or journal D. Within the cup 0 are placed a number of rollers, a. a, which bear against the inner periphery of the cup and the outside of the pin, so as to reduce the friction at the center. The turn-table F is deeply grooved on its under side to form an annularchannel, in which are placed a number of beveled rollers, b b, which run upon the upper edge of the circular rim A, the two sides of the annular channel fitting over the upper edge of the rim A, as shown in Fig. 4., to retain the rollers and turn-table in proper place.

The rollers 11 are beveled on their edges and made convex on their outer faces, so that in traveling around on the track or rim A they will touch the outer wall of the recess in the turn-table F only at a single point in the center, and thus reduce the friction to the minimum.

In the turn-table, at one side of the center, is formed a cup, Gr, provided with a cap, H, which has a central orifice with an upwardlyprojecting flange, d, around the same.

1 represents an upright hollow shaft, the lower end of which is solid and formed with a spindle, f, that extends down through the opening in the cap, and into an aperturein the bottom of the cup G. The lower end of the shaft 1 also forms an inverted cup, 6, which fits over and around the flange cl and forms the lower bearing for the shaft. The upper end of the shaft I forms a cup, J, on top of which is placed a cap. L, held firmly in position by means of braces K K connecting with the turn-table. The cap L is provided with a central spindle, h, which extends down through the cup J into the shaft I, and also with acircular flange, t, which fits around the upper edge of the cup, and thus forms the upper bearing for the shaft I.

On the shaft I is secured a casting or head, M, in suitable bearings upon which is placed the shaft m, that carries the wind-wheel N. On the shaft m is an eccentric, n, which operates the rod 11, and said rod extends downward through a clamp-guide, O, fastened to the lower end of the shaft 1. The lower end of the rod or pitman p is formed with an eye, through which is passed a curved rod, 8, pro jecting from the inner end of a lever, 1?. The curved rod 8 is made on the are of a circle having the axis of the shaft I for the center, for a purpose that will be hereinafter explained.

The lever I? is attached to a shaft, t, which has its bearin gs in two oil-boxes, R It, attached to the turn-table F, and covered by suitable caps. Within each box R the shaft 13 is provided with a pulley, '21, and a band, to, passes over the same. This band passes around a pin or roller, 00, in the bottom of the oil-box and conveys oil up to the shaft, so as to lubricate the hearings on both sides. The outer end of the lever P is provided with an adjustable balancing-weight, S. Near the inner end of the lever, on one side, is a projecting stud, 3 on which is placed the pump-operating rod .2.

In operation the weight S on the outer end of the lever aids in raising the pump-rod and balances and equalizes the motion perfectly, and the weight may be adjusted out or in, so as to make the balance even.

One of the braces K is extended, as shown in Fig. 2, and has the vane T attached to it in a line with the wind-wheel shaft on to keep the wheel in the wind.

To a pin or screw, to, in the clamp O is attached one end of a spiral spring, V, which passes around the clamp and shaft, as shown, and the other end of said spring is attached to the turn-table. The spring V may be adjusted or regulated to any tension desired, according to the power of the wind desired to be controlled.

As the wind increases beyond the power of the spring the wheel and the head M turn to one side more or less, and the pitman 1) moves outward on the curved rod 8, so that the motion will at all times be the same. When the wind lulls the springV brings the head M and wheel N back into their former position.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a windmill, the combination of the base A B, forming the central cup, 0, the turn-table EF, formed with overhanging flange, as shown, and provided with the hollow center-pin or journal D, the horizontal rollers a in the cup 0 around said center-pin, and the beveled rollers b, having convex outer surfaces and placed on the rim of the base within the overhanging flange of the turn-table, substantially as and for the purposes herein set forth.

2. The combination, with the turn-table of a windmill, of the cup G, cap H, with flange d, shaft I, with spindle f, inverted cup 6 and cup J, the cap L, with central spindle h and circular flange i, and the braces K, all constructed substantially as and for the purposes herein set forth.

3. In combination with the pitman or 0011 meeting-rod that is operated from a wind-wheel shaft, a balanced lever provided with a curved rod passing through the lower end of the pitman, and the pump-operating rod connected to a stud on the lever, substantially as herein set forth.

4. In a windmill, the combination of the shaft I, the head M, carrying the wind-wheel shaft, pitman 1), operated from said shaft, guide 0, balanced lever P, with curved rods, and the spring V, all constructed substantially as and for the purposes herein set forth.

5. The combination, in a windmill, of the balanced lever P, interposed between the windwheel pitman and the operating-rod, shaft 1?, with pulleys o o, oil-boxes R R, bands 10-20, and the pins or rollers it :10, all constructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 23d (lay of January, 1880.
