In the drawings, A represents the corner posts or uprights forming the tower, the entire posts not being shown in full length, as they can be of any of the ordinary and wellknown forms of construction and arrangement.
B is an annular ring or plate located within the space of the four uprights A, and connected to each upright by an arm or bracket, B, cast or otherwise formed with the plate B, each arm or bracket having a fork, b, to receive the corner of the post A and be secured'thereto by bolts a.- The upper face of the plate B is smooth, and its inner periphery is provided with a series of cogs or leaves, 1), extending entirely around the periphery, and, as shown, from the under side of the plate, running to a common center, I), are arms B, which form a spider to brace and support the plate B, the center I) being in the form of a hub or collar. 0 is a flat ring located above the plate B.

L is the wind-wheel shaft, having at its inner end a gear, L,which meshes with the beveled pinion h, and having attached to its outer end, in any firm manner, the spider K, for the wind-wheel arms or blades 1 the spider and arms being of the usual construction.
M is a tubular head or collar located around the bearing or sleeve K, so as to be free to slide forward and back on the sleeve K to turn the sails into or out of use.
N is a ring or collar encircling the slide M and free to turn thereon with the rotation of the wind-wheel, and, as shown, the connection between the collar N and slide M is formed k by a flange, m, on the slide and a flange, m,
on the collar, over which flanges a cap or boxing, a, fits, locking the collar and slide together, so that the collar moves with the slide, but is free to revolve thereon. The connection between the collarN and the wind-wheel is made through the bracket or arm k, attached to the wind-wheel arms, and supporting a triangular piece, Z, one corner of which is pivoted to the bracket by a pin or pivot, k, and another corner of which is connected with the collar N by a link, Z, and to the other corner of which is connected a socket, 0, which receives the lower end of the rod by which the sails are turned.

U is a collar mounted on the tube Land having a socket, a, in which is secured the lower end of the rod T by a set-screw, t. This collar U has an annular groove therein to receive a ring, U, as shown in Figs. 1 and 2.
V is a fork, the arms of which are pivotally connected with the ring U on opposite sides, and this fork V has an arm portion pivotally mounted on a shaft, 12, in brackets 1), attached to the posts A, and each sideof the fork has an arm or extension, V 'V.
\V and Z are wires running from the arms or extensions V and V, to be within reach of the operator on the ground or other support for the tower.
The plate or support B is attached to the corner posts A by the brackets B at the proper height for the location of the auxiliary turn-table, and the plate O,with the traveling shaft D and gear-wheels F on the traveling shaft and antifriction rollers d, is placed on the plate or track B. The plate E is dropped into place to rest on the anti-friction rollers cl, and the tube or hollow shaft I is connected with the hub or center 0, connecting the plate or track E with the tube I. The shafts H H are then placed in position and the gearwheels G G connected therewith and brought into mesh with the gear-wheels F, which completes the connection of the auxiliary turntable with the shafting. The wind-wheel is connected with the tube I through the head or collar J, arm J, tubular bearing K, shaft L, and spider K on the shaft L, and the motion of the shaft L is transmitted to the vertical shaft H through the gears L h, as usual, and such rotation is transmitted to the lower vertical shaft, H, through the gearing F, G, and G. The wheel is swiveled to the tower, so as to turn freely with every change of the wind by. the head J, which turns in the collar j, attached to the tower, and with every change of the wind the wheel will be swung around.
In the use of common beveled gearing for power-windmills having a turn-table swiveled in a fixed tower the reaction of the vertical shaft on the swiveled turntable is exactly equal to the power being transmitted through it, and which operates to turn the wind-wheel away from the line of the travel of the wind, and thus destroying its effectiveness. The reaction of the vertical shaft is caused by its resistance to the motive energy of the power being delivered to it, and hence always acts in the opposite direction from what the motive ICS force is operating. The reaction of the vertical shaft H upon the swiveled turn-table .of the mill tends to turn it in the opposite direction from that in which the shaft H is being driven with a force exactly equal to that imparted to the shaft H. This force or strain thrown upon the swiveled turn-table will be imparted to the tube I and plate E, secured to its lower end, and as plate E rests upon and has a geared contact with the rollers 01, which rest upon and have a geared contact with the plate B, fixed to the tower, it will be seen that this reacting force operates on the rollers d in exactly the same manner and with exactly the same force as the power which is being transmitted through the gear-wheels E operates on them, but in the opposite direction, both of them operating as levers prying over their journals as fulcrums, and as the journals of both are fixed in the turn-table 0, these forces, working in opposite directions, meet and are exactly balanced in turn'tableO. It will also.
be seen that the strain thrown upon plate B by geared rollers dis exactly equal to the strain thrown upon gearing g by gears F, but in opposite directions. Thus the reaction of vertical shaft H is transmitted through tube I, plate E, geared rollers d, and plate B to the fixed tower of the mill, and the power of the Wind-wheel is transmitted through shaft L and gears L h to the vertical shaft H, gear-wheels G, F, and G, and thence to the driven machinery, and all reacting tendency perfectly balanced. The sails of the wind-wheel are thrown out of the 'wind by the operator taking hold of the wire W and pulling down thereon, which carries down the arm V of the fork V and raises the end of the fork attached to the ring U of the sliding collar U, raising such sliding collar and carrying up the rod T, which raises the weighted end of the lever or arm S, carrying down the other end thereof, which, through the bars 8 s, throws the lever B backward, carrying with it the connectingrod Q, withdrawing the sliding collar M, and such withdrawal of the sliding collar through the connection thereof with the rods 0 turns the bell-lever P to throw the sails out of use,
and when the wire W is released the parts are brought back to their normal position by the weighted end of the lever S being carried down by the weight. Should it be desired to increase the speed of the wind-wheel, it is obvious that a weight may also be attached to the lower end of wire Z by the operator on the ground. The rod T, passing through the slot j of the head J, is carried around with the rotation of the head, so as to maintain the same relation between the sliding collar U and lever S with the tube or hollow shaft I, on which the sliding collar is mounted, by which arrangement the hand shifting devices are always in position for use, as the fork V remains unchanged in position,
the sliding collar turning in the ring U, which ring is held stationary by the fork.
The arm'V, with the wire Z thereto attached, enables the operator to lock the weighted arm firmly against upward movement, so that, if desired,tl1e sails of the windwheel can be held in one position without liability of changing,and this arm, with its wire, can also be used, if necessary, for the purpose ofvdrawing down the weighted lever S to turn the sails into operating position. The rod T, through which the sails are operated, by this arrangement is located outside of the tubular shaft, thus enabling the vertical shaft H to be placed within the tubular shaft I without interference from the shifting-rod, and as this rod is carried by the tubular shaft it is always in the same relation to the parts which it operates, rendering it at all times in condition to perform the office for which it is de-' signed.
It will .be seen that when the wind-wheel is at rest and the turn-table formed by the parts J J of the mill is rotated around the tower the gear-wheels F perform the same office in tracking on the gear-wheels G G that the geared rollers d perform in tracking on the surfaces of the plates B and E, and this movement does not move or affect the windmill shaft L in its bearings or rotate the vertical shaft H, thus demonstrating that the upright shaft is swiveled as effectually as the wind-wheel itself is swiveled in the tower.
This arrangement of a secondary or auxiliary turn-table produces an effectual counterbalance or compensation for the reaction of the vertical shaft H on the wind-wheel shaft L and its transmission to the turn-table or swivel J J of the wind-wheel shaft, for the reason that the force of the gearing of the wind-wheel shaft to rotate in one direction is counterbalanced or counteracted by the force of the tubular shaft in the opposite direction, thus maintaining a perfect equalization between the two forces, by which no strain is transmitted to the wind-wheel shaft and its bearings.
