ILLINOIS, ASSIGNEE 0F DANIEL HALLADAY.

IIHPRVBIIENII.'y IN WINDMILLS.

-Toallwhomitmyeoncerm Y Be itlmown that I, DANIEL HALLADAY, of Batavin, in the county of Kane and State of Illinois, have inventedl ai, new and useful Improvement in Windmills; lnd'I dohe'reby declare that the following is a full,

' clear, land exact description of the same, 'reference be-- in?! had to the annexed drawing making a part of specification, in which- 1 is a side elevation of my improved'wind'- mill, with the foundation broken away at A', showing the water-pipes of the governor.

Figure 2 is a face view of the wings or sails, and the mechanism for turning them.

Similar letters of reference indicate corresponding I ports in the two figures.

, The nature of my invention consists in having the 'wings or lsails attached to movable or rotating spinhaving levers or equivalent devices connected to them, said levers or their equivalents being also connected to a head, which rotates with the wings or sails, und upon the same shaft, the head having a lever connected to it, which is operated by a governor, which slides thehead upon the shalt, and causes the levers or their equivalents to turn the wings or sails, so as to present a proper resisting-surface to the wind, and thereby produce a uniform velocityof the wings or `sails, which are made to have a greater or lesser obliquity,`according to the velocity of the wind.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it. v

A represents a horizontal shaft, which works in suitable bearings, d a, upon a cap, B, said capB working loosely upon a circular plate, C, attached permanently to s proper support or frame-work, D, (see fig. 1.)

The shaltAprojects some distan beyond the edge of the cap B, as shown in iig. 1, au has a wheel, E, attached permanently to it.

F represents the wings or sails, which are secured to spindles b, said spindles passing radially through the rim ofthe wheel E, and into its hub, the spindles being-prevented from withdrawing by collars c, which Yheer against the inner edge of the rim, and bearings d, (see iig. 2,) which are secured by screws over the spindles, the spindles being loose in the wheel E, and allowed to turn upon their axes. Four wings or sails `are nprcsented, but any proper number may be used. G is a head, tted loosely upon `the shaft A, and having prqiections, e, at its front end, to which pojcetions small levers, f, are attached by pivots g, the outer cnds'of the small levers h being secured tothe -cnds of connecting-rodsf by pivots i. The levers Itv it, in which groove a forked lever, H, tits, (see fig. 1.)

.'.l'hocbedule referred to the Letters Patent und making part cl the sans The lever H is bent,and has its fnlcrum at k; and to the outer end of the lever H a wire orrrod, I, is attached, said wine or rod passing down in a groove, l, in a vertical rod, J, tlieupper end of which is connected toa crank, K, on the inner end of the shaft A by a connecting-rod, L.

The lower end of the wire or rod I is attached to a.-

,sliding head or boss, M, on. the rod J.

N is a spring, one endvof which is connected to thevertical portion of the bentlever H, and the opposite end toa projection, m, on the inner bearing a of the shall; A.

The sliding head or boss M, on the r0.1 J, has a recess, n, in it, in which a fork at one end of a lever, 0, lits, said lever 0 having its fulcrum at p.

The opposite end of the lever O is attached, by a pivot, to'a piston-rbd, P, the piston of which works within a cylinder, Q, (see dotted lines', iig. 1.)

R represents a reservoir containing water, and

T' is a pipe, which communicates with the reser voir, and, with a pump, T, a valve, b', in the lower part of the pump being placed directly over the end of the said pipe T', as shown in lig. 1.

T" represents a pipe, communicating with thc pump T and an air-chamber, Q', that end of the said pipe T entering the chamber heilig provided with a valve, c', as shown also in fig. 1. y,

T' is a pipe, which communicates with chamber Q and cylinder Q, and also with a pipe, S, thc latter re` tnrnin g water to reservoir R.

U is a cock in the pipe S.

V is a horizontal vane attached to the cap B, for the purpose of keeping the wings or sails F facing the wind.

W is a spring attached to the lever O.

Operation.

- The reservoir R is lilled with water, and the wings or sails F, wheel E, and head G rotate with the shaft' A, and the crank K, at the inner end of the shaft A,

works tlie piston-rod J of the pump T, and the water Y in the reservoir It is, by means of the pipe T',taken into pump'T, from which, by means of a pipe, T", it (the water) is forced into the air-chamber Q', and from thence into cylinder Q, the water 'returning to the tank R through pipe S.

'In case the shaft A revolves too rapidly, Ithe cock U is somewhat turned, so as to check the flee passage' of the water through the pipe S; and the water will then be forced against the under side of the pisto'in the cylinder Q, and will raise it, andthe head or boss M will, consequently, be moved downupon the rod J, (see arrow 1,) and the wire or rod I will draw down ward tlfe horizontal arm of the lever H, while the vertical arm will force outward the head G on the shaft A, (see arrow 2,) and the levers h and rod f will turn the spindles b, and the wings or sails F will move obliquely to the wind, and the motion of the mill will be decreased in a corresponding degree.

llhen it is desired to increase the motion of the mill, the cock U is opened, and, the water having a free passage through the pipe S, the head or boss M is raised upon the rod J, and the head G, on the sha-it A, brought back to its original position by the spring N,the wings or sails presenting a greater surface to the wind.

The spring W causes the lever 0 to resurneiits origi- .nal position, or depresses the piston in the cylinder Q, v when the water has a free passage through the pipe S.

The windmill, as above described, is arranged for operating a pump, and the arrangement of the reservoir R.l and cylinder Q with the pipe-connections merelyV acts'as a governor, it being understood that, inpractice, the pump T draws the water from a well, instead of the reservoir, R, herein shown.

The above arrangement would b'e most economical where pumping alone is required; but in other cases, as in grinding grain, churning, thrashing, 85o., a ballgovernorA would he operated by the rod J, or otherwise, which would then be connectedto the shaft A by bevel-gearing, and have a rotary motion.

I do not contue myself to any particular form or kind of governor.

The above mill is more particularly designed for farmers use, and in other eases where a moderate power is required. They are not expensive to manufacture,

I do not claim attaching the Wings or sails to spin` dles b, which turn on their axes irrespective of thearrangement for turning said spindles, in order to give them the desired Obliquity, and thereby presenting a greater or lesser surface to the wind; but

I claim as new- 1. The combination of the connecting-rods fand levers h with the sliding head G and spindles b of the wings or sails, for the purpose set forth.

2. rJJhe combination of the sliding head G, arranged to regulate the Obliquity of the wings or sails and the lever H, with a governor of proper construction, for the purpose of giving the desired Obliquity to the wings or sails, as set forth.

3. A sliding head, G, connected .to the spindles b (of the wings or sails) by means of the connectingrods f and levers h, in combination with lever H and a governor of proper construction, for the purpose of giving the desired Obliquity to the wings or sailsand thereby insuring an equal motion and power with a variable velocity of wind.
