DRIWNGMECHANISM' FOR WINMELLS;

SPECIFICATION fdrming part of Letters Patent no. 616,134, dated. December 20, 1898. Application filed January 24,1898 Serial No. 667,736.. (Ni) model.)

To all whom, it may courier/1,:

Be it known that 1, LA VERNE W. N'OYES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi nois', have invented a certain new and useful Improvement in Driving Mechanism for Windmills, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a combined grinder and driving device for windmills, my object being to provide an improved construction whereby a grinder or other mechanism may be attachedto and driven by the lower end of vthe vertical. shaft of ageared windmill-and whereby in addition means may be provided for driving one or 'more other machines or mechanisms situated near the base of the windmill-tower.

I have illustrated my invention in the accompanying drawings, in whichner in which my invention may be applied to' the driving of any one of a number of different machines or mechanisms. Fig. 2 is a sec tional view showing the manner of connect ing the grinder and the auxiliary driving mechanisms to the lower end of the windmillshaft. Fig. 3 is a side elevation of the casing of the grinder. Fig. 4 is a view thereof from beneath. "Fig; 5 is a sectional view illustrat ing the ball-bearings of the lower end of the vertical shaft. Fig. 6 is a view illustrating the support of the grinder and the lower JOUI". nal-box of the shaft. Fig. 7 is a view of an arm for supporting the belt-guiding rollers or pulleys. Fig. 8 is a view of an adjustable arm supporting a single pulley or roller.

Like letters refer to like parts in the sev eral figures.

The lowerend of the shaft a,which is geared to the wind-wheelof the mill, is journaled in rries at the lower end the casing c of the grinder or other mechanism, the grinder being provided with a hopper 0, bym'eans ofwhich the grain may be fed thereto, the grinder havingupon the interior of the casin g a grinding-ring c opposed to the face of which is provided a grindingring 0 carried upon the support a, which is secured to the lower end of the shaft a and rotates therewith: The grain passing in through the hopper cf works outward between the grinding-faces of the rings a c and passes downward into a receptacle, which may be provided therefor beneath the end of the easing a. In the lower end of the part c is carried a bearing-block d, the lower face of which is of somewhat conical form, being gradually curved from the center toward the edges to form oblique bearing-faces, which tend to press the balls (1'' outward against the curved bearing-faces provided in the upper end of the block d which is mounted in the end of the adjustable nut d screwing in the lower end of the casin g c. Thenut d is hollow, and a central hole (1 is provided through the block 61 so that any dust or dirt that may work into '0 is hollowed, so that the edges '0 thereof project downward below theball-bearings, so

that there is little tendency for the dust and chaff to pass into the bearings; but what little dust finds access to thebearing-surfaces finds a ready exit through the opening (F. The nut d is providedwith a notched periphery 01 into the notches of which a pivoted: lever cl is adapted to rest by gravity to maintain the nut in any adjusted position.

Upon the shaft or abovethebearing-sleeve or barrel b is keyed a pulley e, having an exterior' rim e and also preferably having an interior rim e both of the rims being adapted to engage driving-belts. Rotatably mounted upon the barrel 1) is an arm f, having a collar f, which encircles the barrel b and which is adapted to'be secured in any adjusted position by means ofa set-screwfh Upon the f ismounted a pair of rollers f and a belt f is adapted to pass around the rim or pulley e and over the rollers f f, and thence around a pulley to be driven, which may be located in any convenient I position. Surrounding the barrel 1) is also provided a pair of supporting-arms h k, the armh having two collars h h encircling the barrel, while the arm k is also provided with two collars I0 I0 encircling the barrel and situated just above the collars of the arm h. The pairs of collars h k and k k are free tomove'relatively,

whereby the armsh and Ir, may he moved rela= tively in to any angular. position .to accommodatethe varying angles at which the belt may i is mounteda rollerk, and a belt 70 pass to and from the pulley. Upon the arm It is mounted a roller h and upon the arm 7.: is adapted to be passed around the pulleys and over the rollers h 0 the belt; then passing to and around a driving-pulley. situated in a convenient positiom By mounting theguiding rollers on separate and independent support ing-arms different angular positions of the" entering and leaving portions of the belt may be accommodated, and the rollers may be readily adjusted for passing the belt around alarge or small pulley or over a pulley arranged in a vertical or horizontal plane.

In Fig. 2 the rollers W k are illustrated in position to accommodate a belt adapted to pass downward after passing over the rollers.

- On-theendi of arm h is illustrated an arm l,

extending upward and adapted to support a roller 72?, whereby the belt may be carried to a pulley situated above the pulley e. A similar arm Z may be provided upon each of the arms h 70 when desired, and separate rollers or pulleys may be journaled upon these arms, or the pulleys h k may be moved from one position-to the other when desired. Where the driven pulleys are always below the drivlug-pulley, the arm Z may be omitted.

In Fig. 1 1 have illustrated the manner in which my invention may be employed when it is desired to provide means for driving any one of a number of machines,

7 such as a saw, a grindstone, a feed-cutter, a corn-sheller, and the like. These various machines may be arranged in a circle around the base of the tower with the driving-pulleys preferably of the same size and arranged so that the belt k may be placed upon the pulley of the particular device which it is desired to operate. The

' belt may thus be moved into any radial position in order to drive any one of the plurality of machines, the rbllers h k and the arms carrying the same being movedto accommodate the belt in its new position. By this construction the driving-shaft of the windmill maybe employed to operate a grinder or other mechanism mounted directly upon the lower end of the shaft, and in addition, by the employment of the auxiliary driving, de-

vice any one of a numberof other machines may be driven at the same time.

. The iower end of the casing c is provided with Walls at rightangles to each other, against of the grinder and driving mechanism.

which the angle-bar o is adapted to be secured by means of the bolts 0 0, the lower end of the angle-bar resting upon the ground or other foundation to thus support the weight The angle-bar 0 is supported and braced in position by means of the braces 0 0 which may be of wood or metal and which are secured at the upper ends to the respective faces of the angle-bar, the lower ends of the braces being securedin position in any desired manner.

Having described my invention, what I substantially as described.

claim as new, and desire to secure by Letters Patent, is- V 1. The combination with the vertical shaft,

'of a barrel within which the same is journaled, a-pulley on said shaft, a pair of independent supports mounted upon said barrel and independently rotatable. about'the same, and a guiding-roller mounted upon each-oi said.supportawhereby the two guiding-rollers may be varied in relative position,

2. The combination with the vertical'shaft of a windmill, of a barrel in which the lower end thereof is journaled, a pulley on said shaft, a pair of arms each mounted on collars surrounding and rotatable about said barrel and a pair of rollers for guiding the belt, one carried on each of saidarms, substantially as described.

3.' The combination with the vertical windmill-shaft, of a pulley having an outer rim and an inner rim lying within the outer rim, two pairs of adjustable rollers, one pair for guiding the belt passing over each-of the said rims, substantially as described.

5. The combination with the vertical shaft, of a bearing-block provided at the end thereof having a conical end, an adjustable nut or part beneath the same, a bearing-block provided on the end thereof having a concave face and a centralv aperture communicating with the hollow interior of the nut orpart,

and bearing-balls interposed between said conical and concave bearing-blocks, whereby dust and dirt entering surfaces may escape through the central aperture, substantially as described.
