IMPROVEMENT IN wlNuMlLLs.

Specification forming part of Leiters Patent `No.111055l4, dated July 1, 1873; application filed April 8, 1873.

To all whom 'it may concern:

Be it known that I, GiLEs MABIE, of Dixon, in the county of Lee and State of Illinois, have invented certain Improvements in Windmills, of which the following is a specitication `My invention consists, first, in the construction of a device for holding the shifting-rod and. pitman or pumping-rod of a windmill. Said device is formed of three castings or forgings, as shown in Figs. 2 and 3. Each half of the principal casting or forging has a semicircular projection, said projection having ears formed thereon, said ears being provided with a suitable bolt-hole; and when said halves of the principal casting or forging are bolted together, the projections form a circular aperture for the reception of the sleeve, which, in combination with the castings or forgin gs mentioned above, forms a swivel. Said sleeve has shoulders formed on its upper and under side, and fits into the circular aperture formed by the projections on the two halves of the principal castings or forgings, the upper shoulder resting on the upper side of the circular projection, and the lower shoulder a-gainst the under side of said projection, thus being held securely in position and turning freely in the apertures of the device, and forming a swivel. This sleeve has an oblong hole out through its center to receive the pitman or pumping rod and the shiftingrod. Said shifting-rod has shoulders so formed thereon that the upper shoulder rests on the upper side of the sleeve,

and the lower shoulder against the under side of said sleeve, and thus securely holding the pumping rod or pitman in position without the use of bolts or pins.

My invention consists, secondly, in the peculiar construction of the forked casting or forging employed to connect the fanshafts of a windmill, such casting or forging being grooved on its under side, and is provided with slot bolt-holes for the reception of the radial arms. This forked casting or forging has on each side of the fork a journal, and on this journal a knob or projection is formed, (see Figs. 5 and` 6,) which knob or projection lits into a 'slot in the -hole of a casting or forging affixed to the endsk of each fan-shaft, more fully explained hereafter. By means of these knobsor projections and the slotted holes the forked casting may be attached to the fanA shafts without the use of bolts or pins, and the journals have free play in the holes of the castings or forgings attached to the ends of the fan-shafts, and by means of the slot bolt-holes in these forked castings or forgiu gs, by means of which the radial arms are bolted or fastened to said forked castings, such castings can be let in or out, thereby tightening or loosening the fan-shafts, and thus holding thein securely in position, and enabling the operator to give more or less rigidity to the wheel7 formed by the fan-shafts, and also cffectuall y preventing all noise in the revolution of said wheel. In castings or forgiugsaflixed to each end of the fanshafts, before referred to, has a circular hole drilled-or formed in its front face, said hole having a slot to receive the knob or projection on the journals of the forked casting or forging, above described, and serving to connect said fan-shafts to said fork-e ed casting or forging and the radial arms, so that when the outer end of the fans are turned in, the slot in the hole is in position to receive the knob or projection on the journals of the forked casting or forging, and when the fans are turned back securely locks said forked casting, and thus bolts or pins are entirely dispensed with, and the fastening or locking is made more easy and more rapid.

My invention relates, thirdly, to the construction of the forked levers and to the manner in which they hold the flange on the hori zontal shaft, and also the manner in which they are connected to the lshifting-rod by means of an elbow entering through a mortise in the main hollow shaft, and thus protecting suchconnection from the action of storm and ice.

My invention relates, further, to the construction of the castings or forgings called ears afxed to and projecting from the center of the fan-shafts, such ears being made in two parts, and their upper ends form, when the two parts are bolted together, a fork, such fork being provided with holes for thereception of the journals formed on each side of a block, enaA bling such block to turn freely on its axis. This block has a hole perforated through its center for the reception of the ends of the con- -necting or brace-rods. The ends of these con- .e maar@ necting-rods are provided with screw-threads and nuts, one above and the other below the block, by means of which nuts the fan-shafts can be placed in any desired position and the fans at any desired angle; but that my invention may be fully understood, I will proceed to describe the same by aid of the accompanyin g drawings.

Figure l is a perspective view of a windmill, showing my improvements. Figs. 2 and 3 represent a perspective and sectional plan view of the device for holding the shiftingrod and pitman or pumping-rod. Fig. 4 is a front elevation of the sleeve, holding the pitman or pumping-rod and the notched shiftin grod. Fig. 5 is an under-side view of my iinproved forked casting or forging employed to connect the fan-shafts. Fig. 6 is a plan view of my improved forked casting or forging lit-v ted into the slotted holes of the casting or forging attached to the ends of the fan-shafts. Fig. 7 is a front view of the casting or forging attached to the ends ofthe fan-shafts. Figs. S and 9 are plan and sectional views of the ears attached to and projecting from the center of the fan-shafts and holding the block, by means of which and the connecting-rods the position ofthe fans can be regulated. Fig. 10 is a side view of the forked lever hold-v ing the iiange on horizontal shaft and connecting with the shifting-rod.

A, Fig. 1, is the main hollow shaft, containing the pitman or pumping-rod E and the shiftingrod F. B is lthe rod, to which the swivel is attached. To the end of said rod B the lever B1 is aiixed, by means of which the shifting-rod F is operated. (l C1, Fig. 2, are two castings or forgings, having semicircular projections C2 C2 formed thereon, such projections being provided with ears G3 C3, such ears having a suitable bolt-hole, C4, Fig. 3, drilled through or otherwise formed therein for the passage of a bolt, G5, Fig. 2, by means of which they are fastened together, and forming, when so fastened or bolted together, a circular aperture, (JG, Fig. 3, to receive the sleeve D, Figs. 2, 3, and 4. This sleeve has shoulders D1 D2 formed on its upper and under side, which rest on the upper and under side of the circular aperture GG formed by the two castings or forgings C102. The sleeve D has an oblong hole, D3, cut through its center to receive the pitman or pumping-rod Eand the shifting-rod F. This shiftingrod has shoulders F1 F2 formed in such a manner -that the shoulder F1 rests on the upper side of the sleeve D, and the shoulder F2 against the under side of said sleeve D, thus securely holding in vposition the pitman or pumping rod E. IThe castings C C1 are attached to the' rod B by means of pins or bolts through suitable holes, asvshown at C7, Fig. 2. The sleeve D, holding the pitman or pumpingrod E vand the shifting-rod F when inserted into the circular aperture C, as shown by Figs 2 and 3, formed by the .projections G2 G2, and then bolted together by means of the bolt G5v 'through the ears G2, forms what is called the swivel of a windmill, said sleeve D having free play in the circular aperture CG. G, Figs. 5 and 6, is a forked casting grooved on its under side, and provided with slot bolt-holes, by means of which the radial arms K are attached to such castings, as fully set forth by the specification of myPatent No.124,499, dated March 12, 1872. Such castings or forgings have on each side of the fork journals G1 formed thereon, such journals G1 being provided with knobs or projections G2 in such manner as to iit and pass through the slotted holes H1, Figs. Gand 7, formed in the face of the casting or forging H, such castn g H being attached to the ends of the fan-shafts I, Figs. 1 and 6. By means of such journals G1 and the knobs or projec-l tions G2 formed thereon the forked casting G may be fastened to theca-sting or forging H at the ends of the fan-shafts 1 without the fuso of bolts or pins, andthe operation is as follows: Vhen the fans lon the fan-shafts l, Figs. 1 and 6, are turned in the slots H2 of the slotted holes H1 are in position to receive the knobs or projections G2 on the journals G1 ou each side of the forked'casting G, and may then be inserted, and when soinserted the fans l are turned back, turning the fan-shafts I and the castings H attached to each of their ends, and placing the slot-hole H1 in a different position from the knob or projection G2, thus securely locking or fastening the fanshafts I and forked castings G together, dispensin g with the usual pins or bolts, enabling the operator to connect or disconnect suchl fan-shafts more easily and more rapidly; and by means of the slot bolt-holes G3 formed inV the castings G the radial arms K are fastened to said castings G, and may be"1et in or out, as required, causing the/castings G, when let in, to press against the faces of the castings or forgings H attached to the ends of the fan shafts I, thus tightening the wheel formed by such fan-shafts I,thus givin g great strength and rigidity Vto such wheel, and eft'ectually prevent ing all noise. L L, Figs. l and 10, are levers affixed with capability of turning on axes Z1 fixed in the main brace A1 formed on or affixed to 'Ethe main hollow shaft A. These levers L, at-

yA4, in the hollow shaft A, and, at L3, is connected to the shifting-rod F in order that such shifting-rod F, when desired, may operate the; levers L, and, by means of their forked ends L2, the flange A3 and boss Ait, thereby givingmotion, by means of the connecting-rods Z, to the boss Z1, in which are formed the bearings for the brace or'connectin g rods O, and, in so doing, altering the position of the fan-shafts I and fans I from time to time, as may be required.

By this arrangement it will be readily seen that the levers L and the shifting rod F are greatly protected from disarran gement or obstruction in working by reason of storms or ice.

The forks L2 are provided with projectionsl in order to give such for-ks a better and more even hold on the ange A3, and to prevent the sacid forks from wearing grooves in the flange A M, Figs. 8 and 9, is a casting or forging affixed to and projecting from the center of the fan-shaftsl formed in two parts, M1 M2, and having projections M3 M4 forming a fork, each half having formed therein semicircular apertures, which, when the halves are placed in position, form circular bearings for the reception of journals N 1 of the block N. Said block N, turning freely on its axis, is perforated through its center for the passage of the threaded ends O1 of the brace or connecting rods O, said threaded ends O1 being provided with a pair of nuts, O2 O3, one above, and the other below, the block, by means of which the relative position of the block N upon the brace or connecting rod O may be adjusted, thereby regulating the position or angle ot' the fans l.
