WINDIVIILL.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed November 2, 1905. Renewed September 29,1906. Serial No. 336,807.

To all whom it may concern;

Be it known that I, DAVID Dory, a citizen of the United States, residing at San Angelo, in the county of Tom Green and State of Texas, have invented certain new and useful Improvements in I/Vindmills, of which the following is a specification.

My invention relates to improvements in windmills, and has for its object the provision of anovel mechanism for communicating and converting the rotary motion of the drivingwheel shaft or spindle of a windmill into a reciprocating motion of the power-transmitting-rod or pump-rod operated by the windmill.

A further object is to construct means for this purpose which will combine a high degree of efliciency with simplicity and durability and which will be comparatively cheap in first cost.

By my construction I am enabled to secure a direct and clear lift of the pump-rod and obviate any frictional contact or rubbing of parts in the operation of the rod itself.

The invention consists in certain novel features of construction and combinations and arrangements of elements of the mechanism for utilizing and converting the power of the wind-wheel, as will be described, and more fully pointed out in the claims.

In the accompanying drawings I have illustrated one eXample'of the physical em bodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof.

In the drawings I have disclosed a sufficiency of the mechanism of a windmill to illustrate the application of my invention, it being understood that other appliances of suitable construction may be embodied as necessary or required.

Referring to the figures of the drawings, Figure 1 is a view in elevation of a portion of a supportin tower for a windmill, showing the windmill and connections in side elevation; and Fig. 2 is a view, partly in section, paken at right angles to the position shown in The numeral 1 designates a supportingtower of ordinary or suitable construction surmounted by a cap-piece or turn-table 2, which is secured thereto in customary manner. The wheel-frame or carriage 3, which supports the wind-wheel and connections, is rotatable on this cap-piece, and at its lower 1 portion said frame is provided with a hollow l circular base 4, between which base and the turn-table or cap-piece 2 a series of antifriction-balls 5 are interposed, traveling in a groove or ball-race between the members, as usual.

The wind-wheel 6 is supported on its shaft or spindle 7, which shaft is journaled in a boX in the frame or carriage 3. The shaft 7 is projected through the frame on its side opposite the wheel 6, and on its end a gear-wheel 8 is secured, which meshes with or engages the teeth of a similar wheel 9, journaled on a stud or short shaft 10 on the frame 3. These two gear-wheels 8 and 9 are connected by a pitman composed of a rod 11 and a sleeve 11, in which said rod is slidably disposed. The power-transmitting or pump rod 14 is connected to sleeve 11 by a link 15, said link being pivoted at 16 to said sleeve.

The directing-vane 17 is supported from the frame by the vertical arm 18 and the horizontal arm 19, the parts being secured by bolts or rivets, and this vane serves as a counterbalancing-weight for the wheel and its supporting-frame, as usual.

In operation as the wind-wheel revolves by the action of the wind its rotary motion is communicated through its shaft to the gearwheel 8, which in turn communicates its motion to the wheel 9. The rotary motion of the two wheels is converted into a reciprocating movement by the vertical rising and falling of the pitman caused by the action of the wheels to which the pitman is connected. Thus the link and power transmitting or are made to partake of a reciprocatory vertical movement, which may be utilized as power in usual manner.

The upper end. of the pitman is slotted at its pivoted point 12, as is illustrated in Fig. 2, to permit of a limited adjustment of the parts.

From the above description, taken in connection with the drawings, it is evident that I have produced a mechanism which fulfils all the conditions set forth as the purpose or object of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, 1s-

1. In a windmill, the combination with a supporting-tower having a turn-table thereon, a wheel-frame having a base and antifriction-bearing between said base and turnpump rods which are attached to the pitman.

table, a wind-wheel with its shaft ournaled in the frame, a gear-Wheel journa-led in the frame, and a similar wheel meshing there with located on the wheel-shaft, a pitman connected to said gear-wheels, and a trans mitting-rod connected to said pitman.

2. In a device as described, the combination with a supporting-tower and frame, of a wind-wheel having its shaft journaled in the frame and a gear-wheel on said shaft, a gearwheel journaled in the frame engaging the first gear-wheel, a pitman connecting the gear-wheels, and a power-transmitting rod connected to said pitman.

3. The combination with a supportingframe of a drive-wheel having its shaft journaled therein, a gear-wheel on the shaft and a similar wheel meshing therewith journaled in the frame, a pitman connecting said gearwheels, and connections to the pitman whereby the rotary motion of the drive-wheel is converted into reciprocatory movement of the connections.

4. In a windmill, the combination with a supporting-tower and rotatable wheel-frame, of a wind-wheel with its shaft journaled in said frame and a gear-wheel on said shaft, a similar gear-wheel ournaled in the frame and meshing with the first gear-wheel, a pitman pivotally connected at its ends with the gear-wheels, a powertransmitting rod, and a link connecting said rod and the pitman, substantially as described.

In testimony whereof I afIiX my signature in presence of two witnesses.

DAVID DOIY.
