$PECIFIOATION forming part of Letters Patent No. 329,770, dated November 3, 1885.
Application filed September 29, 1885. Serial No. 178,532. (No model.)
To all whom, it may concern.-
Be it known that I, GEORGE II. PATTISON, a resident of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in VVindmill-Gearings; 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 of the class known as power-mills, as distinguished from pumping-mills.
The invention is fully described and explained in the following specification and shown in the accompanying drawings, in which- Figure 1 is a central vertical section of a windmill-tower and one form of myimproved gearing; Fig. 2, a similar view of a modification of a part of the gearing, and Fig. 3 a similar view of a modification of the upper part of the gearing.
In the first figure, A are the posts of an ordinary tower, and'D is a top plate fastened to the posts. 0 is a turn-table resting on the top plate,but separated therefrom by anti-friction balls, permitting the free rotation of the turntable, and c is awind-wheelshaft journaled in a bearing, d, which forms part of the turntable. F is a miter-gear mounted rigidly on the inner end of the wind-wheel shaft, and E G are two similar gears engaging with the gear F at its highest and lowest points, respectively, the gear G being rigidly mounted on a hollow shaft or sleeve, 0, journaled in the turn-table, and the gear E being rigidly mounted on a preferably hollow shaft, M, which is journaled in the top of the turn-table, and also in the sleeve 0, through which it extends, and below which it projects. At one side of the vertical axis of the mill are two independently-journaled vertical shafts, M M, one above the other, the lower of said shafts being the power-transmitting shaft of the mill, and on the shaft M is mounted loosely a sleeve, 0. The sleeves O O are connected by spur-gears 1 2, mounted on the respective sleeves, and the shafts M M are connected by spur-gears 3 4, mounted on the shafts,respectivcly. A miter-gear, H, is fastened rigidly to the sleeve O,and a miter-gear, L, is cast integrally with the gear 4, or otherwise fastened rigidly to the shaft M. It is evident that if the wind-wheel shaft 0 be ro tated the shafts M 0 must turn in opposite directions, and since the gears H L turn in opposite directions, they bear the same relation to each other as if they were mounted on the shafts O M, respectively, instead of on the shafts O M. In other words, the shafts O M are really continuations of or substitutes forthe shafts O M, and are set at one side of the axis of the mill merely for convenience in construction and operation. The remainder of the gearing, which is precisely the same as that shown in my PatentNo. 308,375, consists of a miter-gear, I, mounted on a stationary shaft, 6, and engaging with the gear H, a double-faced miter-gear, J J,mounted loosely on the shaft M, and having the face J, in engagement with the gear I, and a miter-gear, K, engaging the gear L and the face J of the double-faced gear J J. The gearK is mounted loosely on a horizontal gudgeon, a, formed integrally with a sleeve, R, which is fastened to the shaft M, so that the gear K has two motions, a rotation on its own axis and a revolu tion about the axis of its supportingshaft M.
The operation of the gearing above described is as follows: When the turn-table is stationary,and the wind wheel shaft rotates in its bearing in the direction indicated by the arrow on the gear F, the gears E G and the shafts O M, with their spur-gears 1 8, turn in opposite directions. The rotation of the gear 1 is transmitted, through the gears 2 H I J, to the gear J, and the rotation of the gear 3 is communicated directly to the spur-gear 4 and the gear L attached thereto, the rotation of the gears J L being in the same direction and at the same rate of speed. This uniform rotation of the gears J L carries the gear K bodily about the axis of the shaft M, and thus rotates the shaft itself, to which the gear K is connected by the sleeve R. Thus the rotation of the wind-wheel shaft in its bearing rotates both the shafts M M in the same direction. On the other hand, if the turn-table be rotated While the shaft 0 is stationary in its bearing, the gears E G turn in the same direction and at the same speed,and consequently the gears J L turn in opposite directions at the same rate of speed. The result of this rotation of the gears J L is the rotation of the gear K on its shaft a without any motion whatever about the axis of the shaft M; hence the rotation of the turntable has no effect on the wind-wheel shaft or the shaft M; but since the rotation of the turn-table turns the gear E, it must also turn the shaft M and gear 3, and consequently the gear 4 and shaft M. Therefore the rotation of the turn-table rotates the upper,but not the lower, of the two shafts M M. In fact the operation of this mechanism is substantially the same as that of the gearing shown in my Patent No. 308,375, above referred to. The difference between the mechanism shown here and that shown in the patent mentioned consists in the transfer of the power-transmitting shaft and the axis ofrevolution of the looselymounted gear from a position coincident with the vertical axis of the mill to a position at one side of the vertical axis of the mill, but parallel thereto.
The form shown in my patent above mentioned is but one example of a class of gearings in which a gear on the wind-Wheel shaft engages with two gears corresponding to the gears E G, and in which the rotation of said two gears is transmitted through other gearing to a power-transmitting shaft, one element common to all of said gearings being a loosely-mounted gear free to rotate on its own axis and to revolve about the vertical axis of its rotating support. In all the forms of the class the axis of revolution of the looselymounted gear may be coincident with the vertical axis of the mill or at one side thereof, as shown and described herein.
The modification shown in Fig. 2 consists, simply, in connecting the sleeve 0 with the shaft M and the shaft M with the sleeve 0, thus changing the direction of rotation of each of the parts 0 M; but since these two parts, in the form shown in Fig. 1, rotate in opposite directions, the reversal of the motion of both has no substantial effect on the operation of the mechanism.
I am aware that many of the features of the gearing shown herein are described in the specification and covered by the claims of the patent already referred to, and I therefore disclaim for the invention constituting the subject of this application all novelty except such as may be set forth in thefollowing claims.
