To ALnWHoM 4Ir MAY CONGERN:

Be it known that I, WILLIAM H. WILEY, of Fredonia, Chautauqua county, and State of New York, have invented a certain new and useful Improvement in Horse-Power; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure I is a top plan view. Figure II is a longitudinal vertical section. l Figure III is a cross-section on line XY, Fig. I.

My invention relates to that class of horse-power machines in which the horses travel around a vertical axis, and give motion to a vertical shaft, by an arrangement of draught-poles and gearings. i vIn the use of horse-power machines, they are frequently required to produce reciprocating motions, as in operating wood-mills; and at other times continuous circular motion, as in operating threshing machines, feedcutters, and other farm implements. The nature ofl my invention consists- First. In extending the frame of the machine (bywhich the vertical shaft and driving-gearing are sup? Aporte(l,)laterally across and beyond the circular road travelled by the horses, and providing said frame extension, tirst, with slides for the reception of a drag-saw cross-head, so that said drag-saw may be operated directly from the central driving-shaft by a pitman connecting said cross-head with a'crank-on said driving-shaft; and secondly, in providingsaid frame extensiouwith bed-pieces fitted for the reception of pillow-blocks, (when the vdrag-saw cross-head and pitman are removed,) to form bearings for the support of a horizontal shaft, receiving A thereof` prevented.

motion from the vertical shaft through the medium of a pair of bevel-gears, and carrying upon its outer end a pulley,.fron which motion may be transmitted to any of the before-'mentioned machines; by which'planl of construction and arrangement the'machine'is readily adapted to the production of either circular or reciprocating motion, and in either form all the parts are firmly supported by the same frame, and any disalignment Second. In providing for. a change in velocity of the main `driving-shaft under a uniform travel of the horses in feet per minute, by providingthe rotating-table, to which the draught-poles are attached, with pinionspindles, placed at varying distances from the axis of rotation of said table, so that pinions of-varying sizes may be used between the stationary cog-rim and main-shaft pinion, to increase or diminish the velocity of the main shaft, as required.

Letters of like name and kind refer to like parts in each of'the figures.

A represents the main frame of the machine, upon which the operating parts are supported, and A repre sents a covered extension thereof, below which those parts are located which transmit the power to the outside 'of the circular road upon which the horses travel'. B represents the main central driving-shaft, which is secured in appropriate bearings formed upon the main frame of the machine, and carries upon its top-a pinion, b. C represerits a table, which revolves upon a chilled cast-iron spindle, C', through which the shaft B passes, and which is located immediately below the'pinionb. Y

Upon this table I securely bolt four `or more vertical arms or spindles D, at unequal distances from the centre of table C, which form appropriate fulcra for the gearing hereinafter described. These spindles or arms are made of cast iron, chilledI or hardened. This renders them capable of resisting any strain which may be put upon them, and prevents their wearing out in conseqenceof excessive friction.- Each spindle has a bed-plate, which is securely bolted to the table C, and each is made hollow, so that a bolt ,may be passed verticallythrough the same, for connecting the table to the draught-poles or levers E. There may be four or more arms or-poles, which are connected inthe centre by means of the strengthening bracket e.- The bolts which pass through the arms oxgjspi'ndles D reach up through the poles, and have a nut upon their upper end, by which means the poles or levers may be attached to and .detached from the table with great convenience and little loss of time.

F represents a circulurinternal gear, which is securely bolted to the top of the main frame A. G G represent spur-wheels, having pinions attached upon their 'under side, which are placed upon two of the spindles D in such manner that the pinion will mesh with the internal gear F, and the spur-wheel with the pinion 6 upon the central shaft B; and hence, when 'the table C is revolved by means of the levers E, the pinion Vb and shaft B will be revolved with an increased velocity, proportionate to the difference in the diameter of the intern mediate spur-wheels and pinions G.

In order to `he able to produce a greater velocity of movement of the central shaft B with the same velocity of the levers or prime movers, I provide an additional set of spur-wheels and pinions, the'diti'erence in the diam eters of which is greater than that of the spur-wheels and pinions Gr G. Thevarying distance ofthe spindles D from `the centre of the table C corresponds withA the difference in size of the pinions, so that they will all properly mesh with the cog-rim. This additional set of gearing is shown in red dotted lines, iig. 1, in the posi'- tion the same occupies when used' in lieu of the gearing G G.' It will be readily seen that where great strength is not an object,`only one spurwheel and pinion of either set of gearing may be used to advantage; but for heavy work both should be used. l

H H are boss-pinions, which are placed upon two of the spindles D, between the driving-gear, They mesh with the internal gear F, and serve to strengthen and steady the movement of theY levers and table. These boss-pinions may or may not be used, as desired, but when only one spurwheel and pinion G should he employed, one of these boss-pinions must always be placed upon the spindle opposite the gearing, for the purpose of preventing unduc strain upon all the operating parts.

I represents a horizontal shaft, supported in hearings upon the adjustable cross-pieces z" z", which are parts of the extension of the frame ofthe machine Af, lUpon its outer end this shaft carries an overhang pulley, d, for which (by means of a belt) power may be transmitted to any one of the various agricultural machines now in use, such as feed-cutters, threshing machines, and the like.'V Upon the opposite or inner end a bevel-wheel, K, is attached, which gears with a corresponding bevel-wheel, L, upon the lower end of the vertical shaft B. This bevel-wheel L is so constructed that it may also be used as a crank, a projection being formed upon one side thereof for that purpose. By this means thepower of the machine may be applied to and Ichanged into a wood-mill b .a sim le and cas chanvre in the connections. The crossieces t" i2 are taken oli` b unscrewin y P y o P Y a holt or bolts upon their upper side, and the horizontal shaft I, bevel-wheel K, and pulley J lifted out of the frame and removed. Then the cross-head m is placed within thelslides m', which are a fixture upon the framework, and a connection between the cross-head and crank4 L is formed'hy means of the pitman n. The crosshead m and pitman n are both shown in red dotted lines, representing them to be used in lieu of the horizontal shaft I, bevel-wheel K, and pulley J. Adrag-saw may be attached to the cross-head m in a common manner, and the wood-mill is complete. v i

The changes necessary to increase or diminish the speed of the driving-shaft may he made easily and in a short time, as may also the changes necessary to produce reciprocating motion, or circular motion, when.

required. y

Both of these features meet a long-felt want of farmers,by whom these machines are principally used. The first enables them to suit the speed to the power and strength of their horses, and the second removes a great diiiiculty, existing in other machines, in the setting up and arrangement thereof for the several kinds of work to be donc.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isV

1. Extending the frame of the machine laterally across and beyond the circular track travelled by the horses, and providing the same with slides for the reception of a drag-saw cross-head, and with bed-pieces forthe horizontal shaft pillow-blocks, in the manner and for the purposes described.

2. Securing the pinion-spindles D to the table C, at varying distances from the centre thereof, so that different sizes of pinions, to gear with vcog-rim F, and spur-wheels, to gear with pinion b', may be used, as and for the purpose set forth. 4
