SPECIFICATION forming part of Letters Patent No. 510,029, dated December 5, 1893.

Application filed May 9, 1892. Serial No. 432,255- (No model.) i

To aZZ whom it may concern.-

Be it known that I, GUSTAV KALIES, of Horicon, in the county of Dodge and State of Wisconsin, have invented a new and useful Improvement in Windmills, of which the follow ing is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in wind mills.

The objects contemplated are the provision of improved means for operating the pump rod whereby a direct movementof the same is insured, novel mechanism for adjusting the vane, and finally other minor objects as will hereinafter more fully appear.

The invention consists in the improved construction and combination of parts hereinafe ter set forth.

In the accompanying drawings, Figure 1, is

a side elevation of a wind mill embodying my improvements, a part only of the Wheel being shown, so as to disclose clearly parts to the rear thereof. Fig. 2, is an elevation of the upper part of the device, at right angles to Fig. 1. Fig. 3, is a detail view of a portion of the vane rod, and its allied mechanism. Fig.

4, is'a detail illustrating the connection be parts throughout the several figures of the drawings.

Referring to the drawings, the numeral 1 indicates the usual tower, and 2 a centrally apertured bracket provided-with legs extending and secured to the uprights forming the tower. The upper ends of these uprights are connected byan annular plate 3, provided with a central aperture registering with the aperture of the bracket, and also with an annular recess or trackway 4. A hollow vertical shaft 5 is inserted through the registering apertures of the annular plate and bracket and is provided near its lower end with a screw 6, the annular plate and bracket both provided with slots extending from the cenduplicate of that illustrated in said figure.

The numeral 8 indicates a casting, provided with upper and lowerv boxes or bearings 9 and 10. Through the upper box passes a shaft 11, upon the outer end of which the wind wheel 12 is fixedly mounted. This wheel consists of the usual oblique blades attached to and radiating from a central band 13. The innermost edges of each of the blades are slotted medially as indicated at 14, and through these slits passes an outer connecting band 15, secured to each blade by angular brackets 16. The hub 17 is formed or provided with radial braces 18, which extend to the outer band 13. These braces are preferably inclined in the direction of the blades so as to present as great an area as possible to the wind and thus assist in the rapid rotation of the wheel. Rotatable in the lower box or bearing is a shaft 19' which carries fixedly upon its inner end a disk 20, the side of said disk facing the wheel being provided with an internal peripheral gearing 21, with which a pinion 22 upon the inner end of the Wind wheelshaft meshes. From the opposite side of the disk extends a crank or wrist pin 23, which has attached thereto the inner end of a pitman24, the opposite end of said pitman articulating with a rocking lever 25, said lever having its fulcrum at the upper end of an arm 26, extending obliquely from the casting 8. This rocking lever is arranged at an obliquity so that its other end'will be on the gear sideof the disk, in a vertical line above the hollow shaft, so as to connect at this point pivotally with the upper end of a pump-rod stem 27. This connection is made through the medium of a link 28 provided at its upper end with an eye receiving a transverse pin or bolt,29, journaled in the bifurcated end of the rocking lever. This link is provided upon one of its edges, as clearly shown in Fig. 4, with a recess, 30, adapted to receive the upper end of the pump-rod stem, the latter bent 'ICO at right angles, and passing through'an aperture 31. This forms avery convenient connection inasmuch as when it is desired to detach the stem 27 it can be accomplished with but the slightest difficulty.

The lower portion of casting 8, upon one side, is provided with laterally extending lugs 32, 32, having their ends concave to conform to the contour of vertical shaft 5,' Wl1il6 staples 33, 33 serve to connect the two firmly together so that the casting and parts carried thereby will rotate with said shaft. The extreme lower end of casting 8 has journaled therein a roller 34, which rides in the recess or guideway of the annular plate 3.

The numeral 35 indicates a vertical shaft having its lower end turning in abearing lug 36, projecting laterally from casting S, and having its upper end passing through an aperture provided in arm 26.

The vane of themill is indicated by the numeral 37, and the rod 38 thereof at its rear end is provided with a collar 39 encircling vertical shaft 35 and turning therewith. A brace rod 40 extends from the upper end of shaft 35 to the vane, while an arm 41 projects medially from shaft 35. The outer end of this arm has connected thereto a chain 42, said chain passing around a horizontally mounted roller43 and thence overaquartered pulley 44 located above the vertical hollow shaft 5. The chain is then conducted through said shaft and is connected at its lower end to a pulling or shifting rod 45. A lever 46 is pivoted medially to the vane rod 38, and a rod 47 is also connected to said pivot and extends to and connects with arm 41. A rod 48 extends from a lug 49 of the casting and connects with one end of lever46. The opposite end of said lever has connected thereto a coiled spring 50, said spring having its opposite extremity engaging any of the series of perforations,5l, of the vane rod, whereby the tension of said spring may be adjusted. It will be seen that by manipulating the pull rod the vane may be readily adjusted so as to throw the wheel into and out of wind, the effect of a downward pull upon said rod being to shift or force the vane around substantially at right angles to the wind wheel shaft, whereby the wheel will be feathered or thrown out of wind. hen this is done, the chain exerts a lateral pull upon arm 41 and partly rotates shaft 35. As this shaft is rotated the vane-rod is necessarily carried in the same direction, and as this takes place rod 48 exerts a pull upon the end of lever 46 and throws the opposite end of said lever in a reverse direction, thereby expanding the coil spring 50. The moment the pull upon the rod ceases, the spring recoils and returns the vane rod to its normal position in line with the wind wheel shaft. In order to preventpossible damage through too forcible contact of the vane rod on its return movement with the casting, I provide the latter with a cushion, consisting of a bolt 52, free to move through a perforation in an extension of the casting, said bolt being encircled by a spring 53 and provided at one end with a nut and at the contact end with a headed portion 54. I also provide my wind mill with an improved brake mechanism consisting of a semi-circular strap 55 normally located around the disk at a slight distance from the periphery thereof. The upper end of this brake is secured to a lug 56 formed upon the castingS and the lower end secured to a bolt 57, the opposite end of said bolt being secured to the collar 39 of the vane rod. It is apparent that as said vanerod is movcdaround at right angles to the wind wheel shaft, as just explained, the brake will be brought into contact with disk 20 and the friction between the two will prevent the rotation of said disk.

Referring to Figs. 5 and 6 of the drawings it will be noticed that the lower end of thehollow vertical shaft 5 is closed by means of two semi-circular plates 58, 58, each of said plates provided with recesses, which register and form apertures for the passage of the pumprod stem and the pull rod. These two parts, therefore, are guided and separatedin their vertical movement. The registering plates are further provided with upwardly extending lugs 59, 59, one of which is provided with a V-shaped recess and the other with a correspondingly shaped tongue fitting the recess. These lugs are held firmly together by means of the screw 6 hereinbefore referred to, which thus serves the purpose of holding the plates in their position against the lower end of the hollow shaft 5. t is to be understood, that the perforations of the plates extend up through these lugs.

The upper end of the pump rod has connected thereto and extending thereabove straps 60, 60. To these straps are secured a collar consisting of two halves 61, 61, secured together by means of bolts.

The numeral 62 indicates a swivel connection for the lower end of the pump-rod stem. This is similarin some respects to the joint connecting the upper end of said stem with the rocking lever. It is of tubular form and provided with an L-shaped recess or slot 63, for the accommodation of the lower end of the stem, which is also bent at right angles at this point and enters a perforation 64. The lower extremity of this swivel is provided with an annular flange 65 fitting into recesses 66 formed interiorly in the two half collars 61. The pull rod also passes through this tubular swivel and extends down between the upper straps of the pump red. It will thus be seen that either the pump rod or its stem is free to be revolved without danger of winding the pull rod therearound, and at the same time said pump rod may be readily detached when desired.

In order to accomplish this detachment all that is necessary is simply to bring the pump rod to a horizontal position, so that the lower portion of the L-shaped slot will be in a line with the angular bend of the pump-rod stem or lever. In such position, of course, the pumprod may be readily withdrawn. It is again attached by bringing the parts to the same relative positions.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is Y 1. In a windmill, the combination, of a wind- Wheel shaft provided upon its inner end with a pinion, a rotatable disk provided upon one face with an internal gearing with which the,

pinion meshes and upon its opposite face with a wrist or crank pin, a pump rod stem upon the gear side of the disk, a pit-man connected to the crank or Wrist pin, and a medially fulcrumed rocking lever having one end connected to the pitman, said lever-extending obliquely over the circumferential edge of the disk so as to bring its opposite end upon the gear side of said disk in a line with the pump rod stem, whereby a connection is formed therewith in a direct vertical line, substantially as setforth.

2. In a Wil1d-lIllll, the combination, of a vane, a rotatable casting or cap, a vertical shaft journaled in bearings formed in said casting or cap the lower end of said shaft rigidly connected with the rod of the vane, an arm extending from and rigidly secured to said shaft at right angles to the normal position of the vane rod, a pulling rod anda chain connecting said pulling rod with the arm extending from the vertical shaft, for throwing the vane at right angles to its normal position when the vertical shaft is rotated, and a spring for returning said vane rodto its normal position after the force applied to the pulling rod has been removed, substantially as setforth. l

3. In a wind-mill, the combination, of a rotatable casting or cap, a vertical shaft journaled in bearings formed therein, an arm extending from and rigidly secured to said shaft,
