GEARING. FOR WINDMILLS.

SPECIICATION forming part of Letters Patent No. 537,982, dated April 23, 1895.

Application filed May 8, 1894. Serial No. 510,473. (No model.)

To @ZZ whom it may concern.:

Be it known that I, MILTON KEYS, a citizen of the United States, and a resident of Fort Vorth, in the county of Tarrant and State of Texas, yhave invented certain new and useful Improvements in Gearing for Windmills; and I do hereby declare that the following is a ful1,`clear, and exact description ofthe invention, whichk will enable others skilled inl after fully described and claimed.

In the accompanying drawings: Figure 1 is a sectional elevation of the upper portion of a windmill constructed in accordance with my invention. Fig. 2 is a similar sectional View taken at right angles to Fig. 1.

In the said drawings, the reference numeral 1 designates the uprights of the tower, which may be of any ordinary or suitable construction. Secured to the upper ends of these uprights or standardsis an annulus or ring 2, provided with downwardly depending arms 3,

` bolted or otherwise secured to said uprights or standards. Seated and rotatable upon this ring or annulus is a rotatable circular plate 4, having a downwardly depending annular liange 5 at its periphery, formed with lugs 6, having inwardly projecting pins 7, carrying rollers 8 which engage under said ring or annulus and hold the rotatable plate or turntable in place. The turntable or plate is also formed with a central downwardly depending iiange 5a concentric with iange 5 forming a circular recess in which is seated a metal ring 5b formed with a number of downwardly depending bearings 5 in which are journaled rollers 5d which rest upon the upper side of ring 2. The turntable is supported by the ring 5b and rollers. Secured to this plate are journal boxes 9, in which is journaled the power shaft 10, having at one end a windwheel not shown, which may be of any ordinary or suitable construction and at the other end provided with a friction-wheel 13, with which engages a brake-shoe carried by the vane 14. Also secured to said plate is a bracket 15, formed with a hole 16 to receive the lower end of the vertical shaft 17, to which the vane 14 is attached. The upper end of this shaft is formed with a conical recess to receive the end of a set-screw 1S, passing through alug 19, formed with said bracket. Secured to said bracket and also to the plate 4, so as to rotate therewith, is aV housing 20, consisting of two plates 21, and a rim 22. Passing centrally through this housing is the power shaft 10, having secured thereto a pinion 23, by which the pump rod is actuated.

The numeral 24 designates the pump rod, having at its upper end the connecting rod 25, which in turn is pivotally connected with the vertically reciprocating slide 26. This slide consists of a metal plate recessed at its center forming a continuous bar 27, provided on its inner side with cogs or teeth 28, with which said pinion engages. The inner ends of this slide are provided with studs 29, having rollers 30, which engage in oblong cam slots 3l, ar-

ranged one above the other inthe same verti.

cal plane formed in the innerl side of one of the plates of the housing. The sides of each of these grooves are perpendicular and parallel with each other, forming vertical ways conn nected together at top and bottom, by the curved ways. The said vertical ways of one slot are aligned with those of the other.

The operation will be readily understood. As the wind-wheel revolves it will rotate the power shaft, which through the medium of the slide 26, and the cogs on the slide will reciprocateV the latter up and down and impart a corresponding movement to the pump-rod which is connected therewith. The rollers 30 work in the slots or ways 3l, and guide the slide in its movement.

By this construction a steady, even, uniform movement is given to the pum p-rod, obviating many of the objections incident to the ordinary crank-connection, thereby rendering the apparatus much more efficient in use.

Having thus described my invention, what I claim is- In a windmill, the combination with the ring or annulus 2, the rotatable circular plaie et, having a downwardly projecting annular ilange 5 at its periphery formed with lugs 6 having inwardly projecting pins 7 carrying rollers S, which engage under said ring or annulus, the downwardly depending annular flange 5, the ring 5l located between said flanges formed with downwardly depending bearings 5c and the rollers 5d, loosely journaled in slots in said bearings, of the housing passing through and secured to said plate 4, the driving shaft passing through said housing and provided with a pinion, the two oblong cam grooves formed on the inner side of said housing, one above the other, and Jthe sides of each of said grooves being parallel and perpendicular, the vertically reciprocating slide having rollers at top and bottom engaging with said grooves and formed with an oblong slot provided with rack teeth with which said pinion engages and the pump rod connected with said slide, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

MILTON KEYS.
