To all whom it may concern.-

Be it known that I, GEORGE I-I. PATTISON, a resident of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Gearings for WVindmills; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in gearings for windmills, its object being to counteract the tendency of the work performed by the mill to throw the wind-wheel out of the Wind.

The invention is fully described and eX- plained in the following specification, and shown in the accompanying drawings, in which- 7 Figure 1 is a central vertical section of windmill tower and turn-table with the gearing in operative position. Fig. 2 is a similar view of a modified form of the lower part of the gearing, and Fig. 3 a similar View of a second modification of a part of said gearing. In Fig. 1, A are the posts of an ordinary windmill-tower. Y B is a top plate, rigidly fastened to the posts, and O is a turntable supported by anti -friction balls 0, which rest on the plate 13. On the lower face of the turntable is a hollow cylindrical neck, G, extending through and journaled in the plate B, and a horizontal box or bearing, D, is formed in: tegrally with the turn-table, and forms the bearing of a wind-wheel shaft, E. In the neck G of the turn-table is j ournaled a preferably hollow Vertical shaft, 01, which is connected with the wind-wheel shaft E by two mitergears, m m, mounted on the shafts E a, respectively, and on the lower end of the neck is rigidly mounted a spur-gear, I, which engages with a spur-gear, H. The spur-gear H and a smaller spur-gear, L, formed integrally with it, are mounted on a vertical shaft, F, whose upper end is journaled in the plate B, while its lower end is j ournaled in a bracket, M, formed integrally with the plate. The spur-gear L engages with a spur-gear, K, mounted loosely on the shaft n, and below the gear, and formed integrally with it, are a neck, K, a horizontal arm or disk, N, and two down ward-extending vertical gudgeons, P, carrying loosely-mounted planet-wheels, T. On the lower end of the shaft 11, below the arm N, is rigidly mounted a spur-gear, O, engaging the two planet'gears T, and an internal gear, Q, engages both of the planet-gears, and is mounted rigidly on the upper end of a second vertical shaft, n, located in the same straight line as the shaft n. The lower end of the shaft n is stepped in a socket in the gear Q, and between the ends of the shafts n n is a cylindrical opening through the gear, corresponding to the internal diameter of the shafts, and continuous therewith.

The operation of the mechanism above described is as follows: When the turn-table is stationary, if the wind-wheel shaft be rotated in its bearing in the direction indicated by the arrow on the gear in the gear m, shaft n, and gear 0 must turn in the direction indicated by the arrows on the gears m 0. The turntable being stationary, the gears I H L K are also stationary, and consequently the arm N and gudgeons P are immovable; hence the rotation of the gear 0 rotates the gears Tabout the gudgeons P in the direction indicated by the arrows thereon, and this rotation of the gears T turns the internal gear, Q, in the direction indicated by the corresponding arrow. The gear Q carries with it the shaft n, and the shafts n it thus turn in opposite directions. On the other hand, if the gear Q be held sta tionary, either by the resistance of the work or by any other means, and the turn-table be rotated in the direction indicated by the arrow thereon, the gear I must turn in the same direction as the turn-table, and the double gear H L must turn in the opposite direction. The gear K,engaging with the gear L,turns in the same direction as the gear I, and carries with it the arm N and gudgeons P, and thus revolvesthe planetgears T about the shaft 1; and since the gear Q is stationary, the gears T roll about its geared face and turn the gear 0 and shaft a in the direction indicated by the arrow on the gear-.thatis, in the same direction that the turntable rotates. As shown,

the gears O T T are all equal, and conse-' quently each rotation of the gear K and arm N turns the shaft 11. four times. At the same time the gears K L H I are so proportioned that for each rotation of the gear K the gear I turns four times-that is to say, the complete shaft 12, is the central rotation of the gear K corresponds to four rotations of the shaft n and four rotations of the turntable in the same direction; hence the turn-table and the shaft we maintain the same relative positions, and the wind-wheel shaft does not turn in its bearing. In other words, the rotation of the turn-table does not turn either the working-shaft n or the wind-wheel shaft E, and the mill can swivel without affecting or being affected by the work.

The form shown in Fig. 2 is the same as that shown in Fig. 1, except that miter-gears O T Q are" substituted for the spur-gears shown in Fig. 1, and the ratios of the gears I H L K are altered to correspond with the change in ratio of the gears O T Q.

In' Fig. 3 the gear 0, fastened to the shaft n, isan internalgear. The gear Q, fastened to the spur-gear,and the gears -H, L are separated (though fastened rigidly to the same shaft) for the purpose of bringing the-"gear K below the planet-gearing O T Q. The only effect of this change from the form shown in Fig. 1 is to increase the speed of the shaft n as compared with that of the shaft n. This change also requires a corresponding change in the ratio of the gears I H L K, for reasons already explained.

Whichever one ofthe forms ofgearingshown maybe used, I prefer to run the shaft 17/ to the foot of the tower, and take the power from it there, rather than at a point higher up in the tower. This is, however, not essential.

In my Patent No. 317,186 I have shown a gearing embodying many of the features of the gearing shown and described in this application. Without specifying the elements of this gearing which are to be foundin said patented form, I'disclaim for my present invention any novelty, except such as is set forth in the following claims, to wit:
