WIND-OPERATED WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 789,042, dated May 2, 1905.

Application filed April 15, 1904. Serial N0v 203,315.

To all whmn it may concern.-

Be it known that 1, LEE W. MAxoN, a citizen of the United States, residing at Johnson, in the county of N emaha and State of Nebraska, have invented new and useful Improvements'in Wind-Operated Water-Elevators, of which the following is a specification.

My invention relates to wind-operated water-elevators, and is in the nature of an improvement on a previous device of the same kind patented to me and bearing No. 232,531 and dated September 21, 1880.

The invention relates more specifically to a new means for controlling the blades of the wind-wheel, whereby they may be so moved in relation to the wind as to become inoperative without the controlling influence of a vane, and to mechanism for producing this result.

It also relates to a retarding device for preventing a too rapid descent of the bucket, and to means for controlling the discharge of the bucket when raised by the wind-wheel, and also, generally, in the details of construction and the combination of parts described in the specification and illustrated in the accompanying drawings.

In the drawings, Figure l is a front elevation of the wind-wheel and hoisting mechanism; Fig. 2, a side elevation of the same; Fig. 3, a sectional view on line 3 3 of Fig. 1 with the parts in position to elevate the bucket; Fig. 4, a similar view With the parts in position to lower the bucket; Fig. 5, a detail view of the bucket and discharging mechanism with the bucket ascending, and Fig. 6 a similar view with the bucket in discharging position. Fig. 7 represents an enlarged detail fragmentary view of the vane-actuating links and surrounding parts.

Referring to the drawings, A is a windwheel mounted upon a horizontal shaft B, carried in a bearing C in the end of a bracket D, which is pivotally mountedin a castingE, forming a turn-table and provided with a central opening E, through which an elevatorrope may be passed, as will be further described, carried at the upper end of a tower F of any usual or preferred construction which will permit the free movement of the wheel around the tower.

The wind-wheel A is composed of a series of blades 1, pivotally mounted at their front edges by pins 2 and 3 to annular rings 4 and 5, carried by radial arms 6 6 6 6, secured to a casting 7, forming the hub of the wheel and carried by the shaft B. An annular ring 8 is pivotally engaged by crank pins or links 9, carried by the edges of the blades 1, at a point intermediately between the rings 4: and 5, whereby the blades by the rotation of rings 8 may be rotated upon their pivots and thrown into or out of operative relation to the wind. The ring 8 has a limited movement of rotation about the shaft B and is controlled in its movement in one direction by rock-shafts G G, mounted in suitable bearings 11 11 upon the arms 6 6, and its opposite movement by spiral tension-springs 12 12, connected at one end to the annular ring 8 and at their other end to the arms 6 6. The rock-shafts G G are formed with angular extensions or crank Qmembers 13 13 at their outer ends and pro-.

vided with short sections 14 14 parallel to the shaft, which enter suitable openings in the annular ring 8 in such manner that the rotation of the shafts G G will impart a rotary movement to the ring 8 around the shaft B, between the hub of the wheel A and the bearing O. The collar His provided with lugs 15 15, to which are attached links 16 16, which slide through bearing-lugs 17 17, mounted on the hub of the wind-wheel and provided with rearwardly extending arms 18 18, which are connected to angular extensions or cranks 19 19, formed on the inner ends of the rockshafts G G at right angles to the extensions or cranks at their outer ends. From this construction it follows that the forward-and-backward movement of the collar H on the shaft B will impart a rotary movement to the shafts Gr G and through the annular ring 8 rotate the blades of the wind-Wheel and throw them in or out of operation.

The movement of the collar H is controlled by a forked bell-crank lever J, pivoted to the bracket D. The upright forked end 20 of this lever engages annular groove 21 in the collar H, and the rearward horizontal extension 22 of the lever rests upon an annular horizontal flange 23, carried by a ring 24, which surrounds and is adapted to slide in a vertical direction upon the casting E, its movements being under control from the base of the tower by a vertical rod K, moved by a hand-lever or any other suitable means, said rod K engaging at its upper end a bell-crank or elbow lever 7c, in turn engaging flange 23. The elbow or bell-crank lever is (seen in Fig. 2) has its upper-end engaging the flange 23 in such manner as to effect a slight upward movement of the flange 23 when the rod K is pulled downwardly, this movement being due to the swinging of the upper end of the bellcrank lever K through the arc of a circle as the lever moves upon its pivot, so that regardless of the position of the lever J its arm 22 may be actuated through operation of the rod K, the free end of the arm 22 of course resting at all times upon the flange 23, regardless of the extent of rotation of the bracket D and parts carried thereby.

In the rear of the bearing in the bracket D is mounted the mechanism for operating the water-elevating device, which consists generally in a drum L, loosely mounted upon the wind-wheel shaft; a tripping-clutch M for connecting and disconnecting the drum from the shaft; a tripping-lever N, controlled by the movement of the elevator-rope for operating the clutch M, and a detent-fan O, operated by the rotation of the drum for preventing the too rapid descent of the bucket. The drum L consists of a cylinder loosely mounted on the shaft and provided with flanges 25, the rear flange being provided with gear-teeth 26, adapted to mesh with a pinion 27, carried on a short shaft 28, mounted in a bearing 29, carried upon the upper side of the turn-table casting E. The outer end of the shaft 28 carries the detent-fan O, which may be of any construction, but is preferably in the form of a series of curved blades 30, adapted to offer resistance to the air and supported and reinforced at their outer extremities by an annular ring 31. Between the drum L and the bracket D is mounted the clutch mechanism, which consists of an angular dog 32, mounted in a collar 33, secured to the wind-wheel shaft with one arm substantially parallel to the shaft and the other adapted to engage a lug 34, carried by the drum L. The dog is normally held out of engagement with the lug by a spring 35, but can be thrown in position to engage the lug by means of a shifting cone 36, adapted to slide on the wind-wheel shaft. This cone is provided with an annular groove 37, adapted to engage the end of a bell-crank lever 38, pivoted to the" inner sideof the bracket D and provided with a horizontal member 39, carrying at its outer end a pivoted link 40, provided with an opening through which the elevator-rope 41 passesin such manis an upright weighted lever P, provided with.

a short arm 43, which engages the annular groove 37 'in the cone 36, the office of which is to hold the parts in their shifted position and prevent accidental displacement of the same when in either position.

The lower end of the rope 41 is attached to a bucket Q, provided at its bottom with a hinged valve opening upward and adapted when raised to enter a casing R, provided with a hinged discharge-spout S.

The casing R is provided with guides 44 44, adapted to slide on vertical guide-rods 45, movement being imparted to said casing by a flange 46 at the lower end of the bucket Q, which engages the lower edge of the casing R and lifts it along its guides. The discharge-spout is hingedto the lower edge of the casing and provided with an elbow 47, which carries an arm 48, provided with a wheel 49, adapted to make contact with a cam-track 49, having an inclined surface 50, which causes the discharge-spout to rotate upon its hinge upon the upward movement of the casing and make contact with the lower end of the bucket. The upper end of the discharge-pipe carries a pin 51, adapted as the spout is turned on its hinge to make contact with and lift the valve in the bottom of the bucket and permit the discharge of its contents.

It is to be understood that the stops on the rope may be moved to allow for different depths of water and heights of tower.

What I claim, and desire to secure by Letters Patent, is-

1. In a device of the class described, the combination with a hub and radial arms extending therefrom, of rings fixedly carried by said arms, blades pivotally carried by said rings, a ring linked to said blades, rock-shafts engaging said last-mentioned ring for moving the same in one direction, means for moving the same in an opposite direction, bearinglugs carried by said hub, links longitudinally movably mounted in said bearing-lugs, extensions carried by said links engaging said rockshaft for rocking the same, and means for actuating said links.
