SPECIFICATION forming part of Letters Patent No. 541,301, dated June 18, 189

Application led February 13, 1892. Serial No. 421,654. (No model.)

T0 all whom, i?? may concern..-

Be it known that I, HENRY H. VELIE, a citi- I zen of the United States, residing at Thorson, inthe county of Pope and State of Minnesota, have invented certain new and useful Improvementsiu l/Vindmills; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable oth-V ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in windmills.

The objects of my invention are, first, to provide a windmill that will utilize the cur-A rent of the air to a greater extent than in ordinary windmills; second,.to provide a windmill with a proper speed governor at or near its base, where it may be readily reached for oiling and regulation; third, to provide a windmill, to the lower part of which may readily be put several beltings in different directions for running several machines at one time; fourth, to provide a windmill that runs with as little friction as possible and whose main wearing parts may be readily replaced by new ones without taking the mill apart or down. I attain these objects by the novel construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure l is a side view of the upper part of the tower and mill with `the wind-wheel in central section. Fig. 2 is a perspective view of the lower part of the tower with the speedgovernor and other parts mounted therein. The intermediate portion of the tower between Figs. l and 2 is cut away. Fig. 3 is an enlarged top plan View of the portion d d of the upper part of Fig. 1. Fig. 4. is a rear end view of Fig. 3 or a rear sectional view on the line u. b of Fig. l. Fig. 5 is a sectional View on the line c c of Fig. l. Fig. 6 is a sectional top plan view of the top collar of the tower and the casting turning therein, taken as on the line d cl in Fig. l. Fig.7 isa detail View of certain parts of Fig. 2. Fig. S is a detail side view of the head turning in the top collar of the tower.

Referring to the drawings by letters, A represents the horizontal timbers at the base of the tower. B are uprights secured to the said cross-timbers A with their lower ends, and with their top ends to an open ended cylindrical casting or top collar O, inside of which is loosely placed a revoluble cross-like casting D, which is formed of the four ribs E and a circular disk or web F which being located inside the cylindrical collar C forms a swivel joint for the windmill to revolve on, in adjusting itself to the different directions of the wind. This revoluble head D is secured to and held in its elevated position by a centrally located rod preferably an iron pipe G, of which the lower end H is secured to or in the top portion I, of' the metallic frame I, Q, N, J. The bottom portion lLof thesaid frame forms a revoluble bearing center upon and journal in the plank K, of the frame-work L, L, mounted on the platform M upon the base timbers A.

The frame N of which I and J are the eX- treme top and bottom, is formed with two side pieces N, which to the right unite and forni the seat O for the ball governor P. From the yside pieces N, extend upwardly the two arms Q, Q, which unite'at their top and forml the frame portion I. Between the upward bent free ends R of the frame N, are mounted on the pin S, two rope pulleys or sheaves T. In the arms A20 of the frame portion I is further secured a pin U, upon the ends of which revolve two other rope sheaves V.

W. W. are braces or arms extending from the frame portion I to the upright bar X which has an overbent top portion Yprovided with a notch, A21 in which the screw buckle or yoke Z4 is loosely inserted and guided. The rigid round iron bar d, the block e, the upright X and the braces W, constitute the frame for the governor P and its connections. The round rod d. is Secured with one end in the frame portion O. of the frame N. and with its other or top end in the horizontal portion Y. of the standard X.l Near the middle of the rod cl. the block e. is secured upon it. Upon this rigid rod d. revolve the governor P. and governor pulleyf. which by the collar f2 is prevented from rising. The upper collar g. of the governor revolves, not direct upon roo the rod d. but upon a tubular extension h. formed at the lower end of the yoke t'. where it is retained between the yoke above it and the set screw collar h2 below it, so that when the governor swings its balls j. outward the yoke i. is drawn downward on the standard (l. and when the balls are at rest or hang down the collar g. and h. will push the yoke upward. Upon the standard cl. is further placed a coil spring la. secured with its lower end to the top end of the yoke 'L'. and its upper end to the sliding screw buckle Z., in which is screw threaded athumb screw Z. the lower end of which bears upon the arm Y. so that by turning the thumb screw Z. the spring k. is stretched more or less according to the resistance it is desired to give the governor' balls when they try to spread outward.

In the block e. a suitable projection upon the frame portion I. is journaled the shaft m. upon which is fixed the toothed cam n. that engages with the teeth at the inner edge of the yoke z'. whereby the cam is swung up and down and the shaft m. is rocked by the action of the governor on the said yoke e'. At the'other end of the rock shaft m. is fixed a double cam o. (best shown in Fig. 7) from the grooved segmental-shaped ends of which extend two wires or wire ropes p. and q. up to the top `of the tower, where they' pass through two apertures fr. in the web F. (see Fig. 6), thence over the rope sheaves s. s. and are secured one of them directto the pin t. in the sliding sleeve u. which by sliding back and forth endwise, tilts the wings of the wheel in more or less powerful position to the wind, as will hereinafter be more fully described. The other rope p. passes over a sheave o. and returning underneath it is also secured to the pin t. The sheave fu. is mounted in its hood w. which is secured upon a sleeve like projection to2. of the frame or saddle m. which is secured upon the top of the swivel head D. which is retained from upward movement by a ring or flange y. screwed onto its ribs from below by the bolts y2 and projects outI under the'lower edges of the head collar C. The

[swivel head D. is provided also with an upper flange (not shown) but which covers up the top of the collar C. so as to prevent snow from falling into the collar, and with the up- Ward projecting arms C5, to which the saddle w is secured.

The swivel-head D. ith its top collar or cover (not shown) and its arms C5 and the frarne or saddle make up what is usually termed the turn-table, and may be formed of one or more pieces or parts. The saddle is further formed with four cross bars A A2 A3 A4 the latter being double or provided with an opening B', as shown in Fig. 4. These four bars are united by the side bars B2, and B3. The vane B4 is of usual construction and serves the usual purpose of keeping the wind wheel against the wind. The shaft C is journaled in the cross bars A and A2 upon two friction rollers C2, arranged between said bars and is kept from upward motion by a cap C3. The rearend of said shaft C is journaled between the three friction rollers D D2 4D3 provided between and journaled in the cross bars A3 and A4.

E E2 are two metallic strips secured by,

nular groove n ear the extremerear end of the shaft. These plates E and E2 inserted in said groove in the shaft keep the latter from longitudinal motion. shaft C is rigidly secured the wind wheel hub F and near the rear end the pulley F2. The rest of the shaft revolves freely in the-above described bearings and in the inner' sleeve to2. The sliding head F2 is provit-led with rigid arms F4. The latter'are, by connecting rods `8o Upon the front end of the i G pivotally connected with the rocking arms G2 secured upon the rock-shafts G2 which are journaled'in the hub F and the ring G4 of the wheel, aud carry at their outer ends the wings or sails H. which maybe of any desired number. The said wings are made in such peculiar shape that the entire wing forms a groove or part of a side of a cylinder with the groove running diagonally from the corner H2 to the corner H3 of the wing. Said shape of the wings serves the twofold purpose of first, gathering the wind toward the center of the wing, thereby causing a greater density of air to press upon the wing. The second purpose is to guide the dead air along the groove from H2 to H3 thereby sending it into the open spaces between the arms or spokes Gs of the wheel, where the life current passing through said spaces can carry it away. 'lhis is a decided advantage over the ordinary windmills, in which the dead air slides off from the front of one wing to the back'of the next wing causing great resistance to the latters forward motion.

The sliding and revolving head F3 is built of three pieces, namely, the main-head in which the arms F4 are secured, and the portion F5, bolted thereto as shown and which is split or made in two halves, so that it may be removed and a new one replaced whenever it wears out, without taking other parts of the mill to pieces. This part F5 of the sliding collar has an annular groove FG in which engage the two hooks F7, which are secured upon the sliding sleeve u. that slides on the stationary sleeve to2. (See Figs. 1, 3 and 5.)

In the planks K. and K of the bottom frame L. L. and in the upper junction of the` metallic frame portions Q. Q. is journaled an upright shaft or spindle K2, upon which is secured a pulley K4, for driving the governor by the belt K5. On said spindle is further secured the pulley K6 which receives the belt K7, from the pulley F2, on the upper shaft C which belt is guided over the sheaves T. and V. and passes through apertures K2 in the swivel-head D. (See Fig. 6.) Finally there ICO IIC

is secured on the spindle K3 a series of pulleys K9, of various sizes, for 'receiving belts from several workingrnachinesthat may be placed in different directions around the base of the windmill and driven by the latter.

K10 is a grooved strip of metal pivoted at its upper end to the yoke 'i'. When it hangs down in its normal position it forms a guide that prevents the cam n. from slipping sidewise out of engagement with the rack at the inner edge of the said yoke i., but when it is desired to disengage the cam from said yoke the guide is swung out of the way as illus'- trated in the drawings, until the disengagement has taken place.

K12, is an arm or handle projecting from the double rope cam 0. l

In operation, the wind wheel' revolves the shaft C', and pulley F2, which by means of the rope or chain K7 revolves the spindle K3, and all its pulleys. The governor being run by the belt K5, acts on the yoke i, cam n. shaft m. and cams o. Ropes p. and q., move the sleeve u. and sliding head F3 more and more toward the tower,"th'e more speed the governor gets. This causes the arms F4, rods G', arms G2, and rock-shafts G3, to/tilt the wings more and more edgewisefagainst the wind, thereby diminishing/the speed of the wind wheel. When it is desired to obtain eX- tra high speed of the mill, the thumb screw l. is turned so as to stretch the spring and thus resist the action of the governor. Again, if it is desired to obtain extra great or eXtra small power, the position of the wings to the wind may be changed by swinging 'away the guide K10, swing the yoke t'. out of engagement with the cam n., set the latter a few teeth up or down in the yoke and swing the guide strip K10, into place again.

If it is desired to stop the mill for a shorter or longer time, the operator disengages the yoke 'L'. fromthe cam fn., takes hold of the handle K12, and by swinging it downward and keeping it there by a weight or other means the wings will stand edgewise to the win'd as shown in dotted lines in Fig. 1, (the upper wing.)
