To (ti-Z whom it may concern:

Be it known that 1, JOHN C. Z1EGLER,I6SiCl ing at Seymour, in the county of Baylor and State of Texas, have invented certain new and useful Improvements in IVindWIotors, of which the following is a specification.

My invention relates to certain new and useful improvements in wind-motors, and it particularly seeks to provide a motor of this character of a very simple construction which will effectively and readilyserve its intended purposes and which is more particularly adapted to be used as a pumping-motor in connection with any suitable pumping mechanism to which it is adapted to be joined, but so constructed that by the substitution of cer tain parts for others the same can be readily changed into a power-motor for any use, if desired.

Generically my invention comprises a motor of this type comprisin a wind-wheel and a power-transmitting shaft, a particular and novel form of gear connection between said wind wheel and power transmitting shaft whereby the rotary motion of the wind-wheel shaft is transformed into reciprocating motion in the power-shaft, a novel means for maintaining the several parts of the gear connection always in operative engagement with one another, and an equalizing device for the wheel to prevent racing thereof, as well as to aid the same in lifting the load during certain parts of its operation. Again, my invention seeks to produce, in connection with a motor of this character, an improved form of brake mechanism for the wind-wheel which is automatic in its operation and which is controlled by the movement of the vane. In its generic nature the brake mechanism comprises a band clutch-brake adapted to be applied to the wheel-hub and an endless chain-drive cooperatively connected with a brake band clutch and with the tail-bone fulcrumshaft, whereby the motion of the vane imparts motion to the endless chain, which in turn applies the brake to the wheel-hub an amount in proportion to the movement of the vane.

\Vith other objects in view than have heretofore been enumerated the invention comprises certain novel construction, combination, arrangement, and details of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in Which Figure 1 1s a perspective of my invention.

Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a vertical cross-section taken on the line 3 3 of Fig. 2. Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 2. Fig. 5 is a vertical cross-section taken on the line 5 5 of Fi 2. Fig. 6 is a vertical cross-section on the fine 6 6 of Fig. 2, the shaft38; and the sprocket segment carried thereby being shown in side elevation. Fig. 7 is a horizontal section on the line 7 7 of Fig. 2. Fig.8 is a detail perspective view of the gear member carried by the reciprocating shaft. Fig. 9-is a detail perspective view of the cam-wheel which maintains the gears in their correlative positions at all times. tion of a modified form of my invention.

Referring now to the accompanying drawings, in which like numerals of reference indicate like parts in all of the figures, 1 designates the'pipe-base for the tower, which base is adapted to be secured to the tower at its top in any approved manner. Rigidly secured to the base 1 is a pipe-section 2, having a bearing 3, provided with a ball-race 4, as shown.

5 designates a supporting-frame for the motor mechanism, which includes a base 6, from which a pipe-section 7 projects downwardly and terminates in a bearing 8, having a ball-race 9, and the pipe-section 7 fits over the pipe-section 2 with its bearing 8 over the bearing 3, and the bearings 8 and 3 receive balls 10 between them in their respective ball-races. This arrangement of parts constitutes the turn-table and permits the frame 5 to turn freelyv on a vertical axis in a manner and for the purposes presently more fully understood. The frame 5 also includes a cross brace 11, having a central vertical squared bearing-aperture 12, which cooperates with the central bearing-aperture 13 of the upper cross-bar 14 of the frame 5 to permit passage of the vertically-held power rod or shaft 15, which also passes through an aperture 16 on the base 6 of the frame 5 through the pipes 1 and 7 and is rigidly connected with the pump-rod 17, as clearly shown in Fig. 2. Thus the frame 5 can turn freely on its vertical axis, while the rod 15 is held from turning by reason of its connection with the non-rotatable pump-rod 17 or in any other suitable manner desired. The rod 15 may also be held from turning by forming the said rod square in cross-section where it passes through either the bearing 13 or the bearing 12. The rod 15 has a squared portion 15 to cooperate Fig. 10 is a side eleva- I and a similarly formed bearing portion near its lower end. The lower bracket-bearing 37, which co6perates with the bearing portion 40 of the shaft 38, is slotted, as at 41, to

permit the shaft 38 being slipped into place,

it being held in its normal position by a pin 42, as shown. The tail-bone 43, which may be of any approved construction, has the usual brace- bars 44 and 45, the bar having a projection 46, to which the furl-chain 47 is secured. The chain 47 passes over the idler-pulley 48, mounted on a stud 49 on the cross-brace 11 of the frame 5. At a point about two inches below the idler-pulley a rod is connected to the chain 47 and passes downwardly through the pipes 1 and 7 and connects with the furl-disk of the furl-swivel 50, to which the tie-bar 51 is also secured in any approved manner. A furl-bar 52 connects with the swivel 50 and the furl-wire 55,

as shown, a guide 56 being provided for the furl-bar 52.

Secured at one end to a bracket portion 57 on the frame 5 is a coil-spring 58, whose other end is secured to the tail-bone 43 to hold the vane in its normal position, a stop-arm 59 being secured to the tail-bone brace to limit the action of the spring 58 and to hold said tailbone at aright angle with the wind-wheel when the mill is at work, the lower end of the bar 45 striking against the base of the frame 5 to hold the tail-bone in a parallel position with the wind-wheel when the mill is at rest.

Secured to the shaft 38 near the base of the frame 5 is a segmental sprocket 60, the movej ment of which is limited by the adjacent upwith the squared aperture 12. The rod 15 projects upwardly beyond the frame 5 and receives a coil-spring 18, which is held in po sition by the check-nut 19, threaded on the end of the rod 15, as clearly shown in Fig. 1, or secured by any other suitable means. The spring 18 serves to equalize the work performed by the wind-wheel for the motor in a manner as will be more clearly explained later.

Mounted on the rod 15 between the upper cross-bar 14 and. the cross-brace 11 of the frame 5 is what I term the rodgear mem l ber 20, which comprises the bearings 21 21, l which are joined together by the oblate gear 22 on one side of the rod 15, while the bearin gs 21 21 are joined by the integrally-formed web 23 on the other side of the rod 15, diagonally opposite to the median line of the gear 22. The web 23 has a wing 24, which cooperates with'the cam-wheel 25, and the cam-wheel 25 is loosely mounted to turn on a stud 26 on the frame 5. The gear portion 22 of the gear member 20 has internal rack-teeth 27, arranged in parallel vertical rows facing each other and connected together at the top and bottom by the curved gear portions 28, which project forwardly from. the plane containing the vertical teeth 27 and merge with said teeth 27 on a curved line having its center at the axial line of the gear member 20 to permit said member 20 to turn freely on the rod 15. The rod-gear member 20 is held in position on the rod 15 by collars 29 and setscrews 30.

31 designates a tubular bearing projecting outwardly from the front of the frame 5, in which the wheel-shaft 32 is mounted. The shaft 32 projects intothe frame 5 toward the gear 20 and carries a pinion 81 at its end, which meshes with the gear-teeth of the gear member 20, as clearly shown in the drawings. The hub of the wheel is in the nature of a bell-shaped spider 33, which is secured to and turns with the shaft 32 and projects over the bearing 31. The spider 33 has the usual radial arms 34, to which the sail-arms may be secured, and the spider 33 also has a brake rim 35 integrally formed therewith at the end adjacent the frame 5. Where the bearing31 is formed on the frame 5 the said frame 5 is thickened, as at 36, to add strength thereto. an angled foot 70, having a plurality of pin On the inner side of the frame, opposite the receivmg apertures 71 to receive the pin 72, bearing 31, is an inwardly-projecting stud 26, which is carried by the chain 62. The other upon which the circumferentially beveled lever 63 has its free end pivotally connected idler cam-wheel 25 is mounted, and the wheel to the lever 66 through a link 73, as shown. 25 coperateswith the wing 24,as before indi- From the foregoing description it will be cated, to hold the gear-teeth of the gear memseen that when the wind-wheel is in operaber 20 always in mesh with the pinion 81. On tion a reciprocal motion will be imparted to the outer side opposite the bearing 31 the the power-transmitting shaft, the equalizingframe 5 is provided with a pair of outwardlyspring serving to prevent racing of the wheel projecting bearing-brackets 37 37, in which on the downstroke thereof, thus forming an the tail bone turning fulcrum shaft 38 is automatic speed-equalizer for the wheel. As mounted, and the said shaft 38 is preferably the vane swings on its pivotal shaft, due to the square in cross-section and formed with a cy- I action of the wind or when drawn over by the lindrical bearing portion 39 at its upper end l furl devices, the motion thereof will beimpartright of the frame 5, and around this sprocketwheel and around idler-pulleys 61 61 at the opposite end of the base an endless chain or cable 62 passes.

The brake devices comprise a pair of curved bands 63 63, fulcrumed at 64 64 to the frame 5, one on each side of the brake-rim 35 of the spider 33, and each band 63 has a brake-shoe 65, as shown. One of the bands 63 has its free end pivotally connected with the operat ing-lever 66, which is also fulcrumed at 67 to the frame 5 and which has a downwardlyprojecting arm 68, having a curved portion 69 to pass the brake-rim, and terminates in IIO IIS

ed to the wheel 60, which causes the endless chain or cable 62 to be moved, carrying with it the pin 72, and thus swinging the brake-operating lever 66 and applying the brake to the brake-rim 35, it being understood that the amount of braking power applied to the frame varies with the position of the vane, being greatest when the vane is in the position shown in dotted lines in Fig. 7. As the gear member 20 ascends or descends with the movement of the rod 15 the wing 24 of the gear member 20, whose upper and lower edges are beveled to correspond with the slant of the beveled idler cam-wheel 25, is brought in contact with said idler cam-wheel, and as the wing slides over the beveled surface of the cam-wheel it is made to rotate on the stud 26, thus changing the position of the wing from right to left with each stroke of the powerrod 15 and at the same time changing the position of the gear portion 22 of the gear member 20 in the opposite direction from that of the wing 24, and thus keeping the internal rack-teeth 27 of the gear member 20 always in mesh with the pinion 81.

It will be noted that this construction requires but little power to impart motion to the power-shaft, as the resistance to be overcome is reduced to a minimum on account of the peculiar construction of the gearing em ployed. Attention is also called to the fact that no more wind-power is required for a long stroke than is necessary for a short stroke, except for the additional weight of water to be lifted in the case of the long stroke, it only requiring more time to make the long stroke. Again, the tendency to hammer, due to the wear caused by the change of the stroke in all mills having a pitman connection and swivel on the end of the power-rod, is entirely eliminated in this construction. Furthermore, owing to the action of the equalizing-spring on the upper end of the power-rod 15 the wear due to friction on the rack-teeth 27 and on the cogs of the pinion 81 is changed from one side of the teeth to the other with each change of stroke of the power-rod, thus prolonging the life of each of these members.

In Fig. 10 I have shown a slightly-modified form of my invention in which the equalizing-spring is eliminated and in which the gear member 20 is removed, a bevel-pinion 75 being secured to the rod 15 in lieu thereof, which pinion 75 meshes with a master-gear 76 on the wind-wheel shaft, as shown, thus transforming my apparatus into an ordinary powenmotor, by which the rotary motion of the wind-wheel is transmitted as rotary motion to the rod 15.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the complete construction, operation, and many advantages of my invention will be readily understood by those skilled in the art to which it appertains.
