GEARING FOR WINDMILLS.
SPECIFICATION forming part of Reissued Letters Patent No. 10,789, dated December 14-, 1886. Original No. 35!,461, dated October 26, 1886. Application for reissue filed November 23, 1886. Serial No. 219,710.
To all whom it may concern:
Be it known that I, Gnonen H. PATTISON, a resident of Freeport, in the county of Stephensop and State of Illinois, have invented certain new and useful Improvements in Gearings for WVindmills; and I do hereby declare the following tobe a full, clear, and exact description of the invention suificient to enable others skilled in the art to make and use the same. I
My invention relates to improvements in gearings for windmills in which the object is to counteract the tendency of the work per-- out of the wind.
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 windmilltower and turn table with the gearing in operative position. Fig. 2 is a similar View of a modified form of the gearing located a modified form of the lower part of the gearing of Fig. 1. Fig. 4 is a similar view of a modified form of the invention, in which most of the gearing is located below the turn-table. Fig. 5 shows the gearing O T Q located lower down in the turn-table than in Fig. 1.
In Fig. 1, A are the posts of an ordinary windmill-tower. Bis atop plate fastened to said posts, and O is a turn-table supported by anti-friction balls, which rest upon the plate B. The lower portion of the turn-table is a hollow cylindrical neck, F, extending through the plate B, and ahorizontal bearing, D, is formed integrally with the turn-table and provides a bearing for the wind-wheel shaft E, while a vertical arm, D, is also formed integrally with the turn-table and provides a bearing for the short, preferably hollow, shaft it, upon which are mounted the miter-gears m 0, the gear m engaging with the gear m on the wind-wheel Shaft E.
The hollow shaft H is journaled in the turntable, and to its upper end is attached the arm or bracket N, bearing the gudgeon P, upon which is journaled the miter planet-gear T. The planet-gear T engages with the miter-gear O, and communicates the motion of the gear O to the miter power-transmitting gear Q, with which the gear T engages upon its opposite side. The power-transmitting gear Qis attached to the power-transmittin g shaft n,which is journaled in the shaft H and tower-plate I.
Formed integrally with or attached to the lower end of the downwardly-projecting neck F is a horizontal arm, G, carrying the vertical gudgeon L, upon which is loosely mounted the double planet gearing w y, the upper gear, at, engaging the gear K, attached to the lower end of the shaft H, and the gear y engaging with the gear Z, mounted stationarily in the tower upon the plate -I.
The operation of the mechanism above described is as follows: When the turn-table is stationary, if the wind-wheel be rotated in its bearing in the direction indicated by the arrow on the gear m, the gear m, shaft 91., and gear 0 must turn in the direction indicated by the arrows 011 the gears on O. The turntable being stationary, the arm-G and gudgeon L are stationary, and the gears w y, journaled on the gudgeon L, are stationary. As the gear 3/ engages with the always-stationary gear Z, and the gear K, engaging with the now-stationary gear w, is also stationary, the shaft H, arm N, and gudgeon l? are also stationary; hence the rotation of the gear 0 rotates the gear T about the gudgeon P in the direction indicated by the arrow thereon, and this rotation of the gear T turns the power-transmit ting gear Q in the direction indicated by the corresponding arrow thereon. The gear Q carries with it the shaft n, and the shafts n n thus turn simultaneously in opposite directions.
On the other hand, if the gear Q be.
held stationary, either by the resistance of the work or by any other means, and the turntable be rotated in the direction indicated by the arrow thereon, the arm G and gudgeon L turn in the same direction and carry the double planet-gears x g bodily in the same direction, and this bodily rotation of the gear y will roll it about the equal stationary gear Z, with which it engages, and rotate it on its own axis L in the direction indicated by the arrow thereon. Now, the gear or, being formed integrallywith or attached to the gear 3 must rotate with it about the gudgeon L. The gear K engages with the gear :0, and is twice the diameter thereof, and as the gear at is carried bodily once about the center of the gear K by ICO ' of the planet-gear T, together with one rotathe gudgeon L, and is also rotated once about the gudgeon L in the direction indicated by the arrow thereon through its connection with the gears 3 Z, the gear K will be rotated half of one revolution in the direction indicated by the arrow thereon-that is, if the gear a: were rigidly attached to the gudgeon L, one rotation of the turn-table arm G and gudgeon L would carry the gear K around once in the same direction, since there could be no action between the gears av Kybut though the gear 00 is carried once around bodily by the gudgeon L, it is attached rigidly-to the gear y instead of to the gudgeon L, and hence isrotated once about the gudgeon L, together with the gear 3 which is caused to roll about the stationary gear Z with each revolution of the gudgeon L, and the gear :10 being half the size of the gear K would thus rotate the gear K half a revolution in the opposite direction or half-way back; but these two motions of the gear w bodily and about the gudgeon L taking place at the same time operate simultaneously on the gear K, and hence cause it to make only half a revolution for each revolution of the turn-table arm G and gudgeon L. The half of a revolution of the gear K is communicated through the shaft H to the arm Nand gudgeon I, and thus revolves the planet-gear T about the shaft 11', and since the power-transmitting gear Q is stationary the planet-gear T is thus rolled about the face of the gear Q and turns the gear 0 and shaft n in the direction indicated by the arrow on the gear-that is, in the same direction as the rotation of the turn-table. As shown, the gears O T Q are mitergears; consequently, as one bodily rotation tion on its axis, would produce two rotations of the gear 0 and shaft n, one-half of one bodily rotation of the gear T, arm N, shaft H, and gear K, will produce one rotation of the gear 0 and shaft 11.. Hence the turn-table and shaft 12. maintain the same relative position 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 a or the wind-wheel shaft E, and the mill can swivel without affecting or being affected by the work, and is therefore balanced.
Fig. 2 shows a slightly-modified arrangement of the gearing m m 0 T Q, located in the turn-table. The shaft n and shaft H are continued upward, and the gears m 0 and shaft 41 are journaled about the shaft Hinstead of in the arm D.
Fig. 3 shows a modified form of the lower part of the gearing that is, the gearsg Z are miter gears and the gears K as are bevelgears in the proportion of two to one. In this figure the gudgeon L is shown as fastened rigidly in the gear and rotating in its own support, and this construction may, if preferred, be used in the forms illustrated in the other figures.
' In Fig. 4 a modified form of the invention, in which most of the gearing is located below the turn-table, is shown. The shaft H passes necessitate simply a relative change in theproportion existing among the gears K m 3 Z.
