SPECIFICATION forming part of Letters Patent No. 241,625, dated May 17, 1881.
Application filed March 5, 1881. (Model.)
To all whom it may concern Be it known that I, DELoss A. DANFORTH, of Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Windmills; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accom pan ying drawings, and tothe letters of reference marked thereon,which form part of this specification, and in which- Figure l is a perspective view of my mill; Fig. 2, a side elevation, partly sectioned, and Fig. 3 is a section through the turn-table.
The object of this invention is to provide means for preventing the turn-table in a windmill from being accidentally raised from its bearings, and also to adapt the same to turn easily; also, to provide improved means for bringing the hinged vanes into the Wind also, to provide means for admitting the pump-rod and raising the water with but little power, as hereinafter fully described, and particularly pointed out in the claims.
A refers to the derrck, which is provided with timbers a a", secured by bolts in the four corners of a rectangular-flanged metal plate, B, that constitutes the top of the derrick. This top plate isformed with a central openin g, in which the turn-table C works. The turntable consists of a cone-shaped metal shell provided at its end which extends above the derrick with the flan ge D,and near its lower end with a llange, D. The object of the Lipper flange, D, is to prevent the turn-tablefrom being raised from the derrick, and to provide a bearing-surface for anti-friction wheels E E, which are arranged upon the top plate of the derrick and provided with anges e, which project over the flan ge D of the turn-table, and hence prevent the same from being unduly raised. A lower plate, F, is secured to the derrick, and provided witha central opening, in which the lower ianged portion of the turntable works, wheels `or disks f being secured to this plate so as to extend over theange D of the turn-table, and thereby prevent-the accidental raising of the turn-table in case the devices rst described for the same purpose should give Way.
Gr refers to a circular band secured to the ends of the radial bars gof a frame or spider,
H, that is mounted upon the horizontal shaft sleeve, l, arranged loosely upon the shaft H,
so as to slide thereon. Thesleeve lis made with a flange, l', from which two rods, M M,
extend back through the radial bars of the i spider and connect with a grooved wheel, N, the said bars or rods being arranged parallel with the axis of the shaft upon which the spider and the hub L are mounted. The shaft passes through al cylindrical bearing, O, and is providedat its end which extends over the turn-table with a crank-wheel, H2, for operating the pump-rod. The bearing O is xed upon a horizontal plate, I), securedto the top of the turn-table, one end of said bearing being extended, as at p, to `form a support for the grooved wheel N, which is arranged to be capable of both a rotary and a sliding or side movement upon said extension of the cylindrical bearing.
In the Lipper end of an upright arm or plate, Q, secured to the turn-table, is supported arockshaft, q, that is provided with an upper central arm, R., and two lower end arms, R R', the latter of which arms connects with two movable horizontal bars, S S, arranged t0 slide upon the plate P, alongside of the guides p p. The
outer ends, S', of these bars are bent upward into the peripheral groove a of the wheel N, but'are made less in thickness than the widthl of the groove, so as not to interfere with the free rotation of the wheel.
To the central upper arm, R, of the rockshaft is connected a rod, T, that passes down `through the turn-table, and is provided at its lower end with a suitable weight.
The pump-rod U, which works through the turn-table, is provided at its upper end with a curved link, V, in which the wrist-pin upon the crank-wheel H2 works, so as to operate the pump-rod. The upper and lower curved bars, n c, of this link are concentric with each other and it will be observed that the arcs formed by these curved bars are" unequal, the upper being greater than the lower one hence the pump-rod will descend `by the action of the IOO wrist-pin upon the lower curved bar of the link more rapidly than it will be raised by the action of the Wrist-pin upon the upper curved bar. By this construction less power Will be required to raise the pump-rod and the water than if the arc of the upper bar were equal to the arc ofthe lower bar, it being obvious that but comparatively little power is required to force down the piston, and that by the arrangement of the upper curved bar no additional force will be necessary to raise the pump-rod and the Water.
The hinged vanes will be brought into the Wind by means of the weighted rod connecting with the rock-shaft, the movement of which causes the horizontal bars S to move and shit t the grooved Wheel upon the cylindrical extension p, the said Wheel causing a like movement of the hub Lf, which connects by means of links with crank-arms upon thehinged vanes. The hinged vanes thus oder to the winda resistance sufficienti y yielding to prevent breakage, and at the same time are kept in the wind, so as to insure operation of the windmill.
In conclusion, I will remark that the outer and inner rings of the wind-wheel can be provided With holes x fr, so that when desired additional lvanes can be provided, these extra vanes being provided with pintles adapted to lit loosely in the holes ofthe said rings or bands 5 also, the crank upon the end of the drivingrod might be taken off and gear-Wheels employed for a like purpose.
What I claim, and desire to secure by Letters Patent, is-
1. The combination, in a windmill, of the turn-table C, having a dan ge extending around its upper portion, with the flanged anti-friction Wheels arranged to bear against said flange,
with vtheir flanges overhanging the same to prevent the turn-table from being raised from the derrick in which it is mounted, substantially as described. v
2. The combination, in a Windmill, of the derrick having its bars secured at their upper ends by a plate, B, with the turn-table G, having the flanges I) D', the plate F, the anti-friction ianged rollers E, and the disks f, the said turn-table passing through and rotating in the two plates, and being prevented from rising from its bearings by the disks and the flanged rollers, substantially as described.
3. The combination, in a windmill, of the spider H, mounted upon the horizontal shaft Which transmits motion to the pump-rod, with vanes-hinged to the radial bars of the spider, a hub provided with vanes and arranged to slide upon the said horizontal shaft, links connecting the hinged vanes with the vanes of the hub, and a weighted rod connected with the hub byintermediate connecting mechanism, whereby the hinged vanes Will be kept in the Wind, substantially as described.
4. The combination, with the rotary shaft in a Windmill, ot` the crank-Wheel upon one end of the shaft and a curved link upon the upper end of the pump rod, the said link having upper and lower curved bars, between which the wrist-pin of the crank-Wheel works, andthe arc of the upper one of said curved bars being greater than the arc of the lower curved bar, substantially as and for the purpose specified.
In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.
D. A. DANFORTH. Witnesses:
