WINDMILL.

This invention relates to an improved wind mill and one object of the invention is to provide a wind mill which is so constructed that reciprocating movement may be imparted to a vertically disposed pump shaft and at the same time permit the pump shaft to rotate with a hollow shaft through which the pump shaft extends, the pump shaft imparting reciprocating movement to the pump rod of an ordinary structure of water pump and the rotating hollowshaft carrying a pulley wheel so that rotary movement may be transmitted to a driven shaft at any point by means of a belt.

Another object oft-he invention is to so construct this wind mill that therotating .hollow shaft may carry at its upper end a 1 carrier above which the reciprocating pump shaft will extendga rocker shaft being carried by this carrier andhaving connection with the pump shaft for imparting reciprocating movement to. the pump shaft and the rocker shaft carrying wings which will be acted upon by wind so that the rocker shaft will be rocked and at the same time the carrier and hollow shaft; rotated.

Another object of the invention is to have the wings so mounted upon the outer end portions of the rocker shaft that when the pump is in operation, the wind in striking one of the wings will serve to impart rocking movement to the rocker shaft and at the same time serve to impart rotary movement to the carrier and hollow shaft. it being understood that when one of the wings is struct by the wind and moved to an operative position, the. wings at the opposite end of the rocker shaft will be swung to an in operativeposition.

Another object of. the invention is to provide the wings with improved bladeswhich are pivotally mounted for movement into and out of an operative position and are normally in an operative position thus permitting the wind mill to operate whenever the wind is blowing as long as the blades or vanes of the wings are not moved to an inoperative position.

Another object. of the invention is to provide improved means for moving the vanes or blades to the inoperative position and to provide actuating means for this means which will be manually controlled and to further provide actuating meanswhich will be controlled by centrifugal force set up during rotation of the carrier and hollow shaft. By'means of this actuating means which is operated by centrifugal force, the speed at which thehollow shaft and carrier rotate may beautoinatically controlled and the shaftand carrier prevented from rotating too rapidly.

Another object of the invention is to so construct this wind mill that the rocker shaft will be prevented from being rotated beyond a desired amount and thus breakf parts prevented.

This lnven'tion is illustrated in the accompanying drawings wherein:

Figure l is a view in side elevation showing the improved construction of wind mill.

Figure 2' is a top plan view with the upper end portion of the pump shaft shown in section.

Figure 3 is a sectional view taken along the line 3-3 of Fig. 2 with certain portions of the wind mill shown in elevation.

Figure 4 is a similar view taken along the line -it4 of Fig. 2.

Figure 5 is a sectional view taken along the line 55 of F ig. 2.

Figure 6 is a perspective view of the manually operated actuating means for the means for moving the blades of the wings to an inoperative position.

This improved wind mill will be provided with a tower construction having corner posts 1 connected by cross bars 2 and having their upper ends connected with a platform or head 3 which may if so desired be provided with a supporting ring 4 to which the corner posts 1 will be directly connected. The pump 5 is of a conventional construc tion and will be provided with a reciprocatingpuinp rod 6 having vertical reciprocating movement when water is being pumped. It will also be provided with an outlet pipe 7 which may lead to a suitable storage tank or to any other point where it is desired to have the water delivered. The pump shaft 8 extends vertically through the tower and about which will. be passed a belt 14; so that as this hollow. shaft 11 rotates, rotary movement may be t ansmitted to the driving shaft of a machine which it is desired totlp lfate by means of power developed by'the wind mill. The upper end portion of the hollow shaft 11 is provided with an outstanding collar or bearinghead15 which is positioned abovea Similar head 16 at the upper end ofthebearing sleeve 10. Antifriction balls 17 will be provided between these collars so that the hollow shaft can readily rotate. It is to be understood that suitable anti-friction balls or rollers can be provided for the bearing 12 and also within the; tubular bearing 10 if so desired. It will thus be seen that the hollow shaft 11 can rotate freely and itwill be further seen that the pump shaft 8 which is to impart movement to the pump rod, (5 mayhave vertical reciprocating movement and at the same time may have rotary movement with the shaft 11, this rotary movement of the shaft 8 being permitted due to the swivelled connection 9 between the shaft 8 and thepump; rod 6.

An elongated carrier platform 18 is socured tothe head or collar '15 at the upper end of the hollow shaft 11 and is provided at this end with upstandingbearing arms 19 which serve to anount a rocker shaft 20 which extends longitudinally of the carrier 18 with its endportions extending beyond the ends of the carrier. This carrier platform 18 is provided withan opening so that the upper end portion of the pump shaft 8 may extend upwardly through the carrier and above the rocker shaft. Arms 2lvextend from this rocker shaft and are loosely connected with the lower end of a. pitman link :22 which extends upwardly and has its upper emit loosely connected with an arm 23 which extenijls from the shaft 8. From an inspection of Figs. 3 and 5. it will be readily seen that when the wind mill is in operationand the carrier platform and roclrer shaft are turning in a horizontal plane the shaft S and hollow shaft 11 will be rotated at the same rate of speed. It will be further noted from an nspection of these figures and Fig. that as the rocker shaft rocks n a manner to be hereinafter brought out,

reciprocating movement will be imparted to the pump shaft 8 while the pump shaft and hollow shaft 11 are rotating. In order to control the rocking movement of the rocker shaft and prevent breakage due to excessive rocking movement and sudden stopping of this movement, there has been provided a bracket 24 which is secured upon the carrier 18 and extends transversely thereof. This bracket 2% is provided at its ends with upstanding bearing arms 25 with'which yokes 26 are loosely connected. These yokes 26 extend inwardly and each slidably carries a stem 27 which is yieldably, held against movement. by means of "a spring 28. An elongated collar is mounted upon the rocker shaft 20 between the arms 21 and one ofthe bearings 19 and is provided with spaced sections or plates 29 which are connected by a neck 30 through which a fastener 31 will pass to secure this collar upon the rocker.

shaft. The stems 27 are loosely mounted between the ends of the sections 29 as shown in Fig. l and from an inspection of this figure, it will be readily seen that when the rocker shaft isturned during operation of the wind mill, the yokes 26 will receive vertical swinging movement and the stems 27 will have longitudinal sliding movement.

This longitudinal. sliding movement will be r'etarded by the springs'28 and therefore these springs will provide brake means to prevent sudden stoppage and consequent breaking of parts. I

In order to impart rotary movement to the hollow shaft and carrier there has been provided wings upon the end portions of the rocker shaft. These wings extend at substantiall ri ht a-n 'les to each other as shown in Figs. 1 and 2 and each is provided with a frame 352 which is substantially U-shaped and has its side arms connected adjacent their free ends by a cross bar or strip 33 having openings formed therein so that fastener bolts 3&inay be passed through the cross bar to secure the frame firmly against the rocker shaft} The end portions of the rocker shaftwill be flattened as clearly shown so that the cross strips of the wings may be securely held in placeand have no tendency towards rocking, movement upon the shaft. The inner side bar of each of the framesis extended thus providing an arm extension 35 upon which will be adyustahly mounted a (EOl'lIlilGl'd'JtlltlllCfi weight 36 so that the properroclnng movement maybe easily imparted to ,the rocker shaft. Vanes or plates 3'7 are positioned between the-side bars .of the win 's and each is rovided with i a pivotshaft These shafts 38 are journaled'in the sidebars of the frame and at one side of the frame, the end portions of these shafts are bent to provide crank elements 39 upon which will be mounted'a strip 40 so that the vanes or blades 37 will all turn together. One of the shafts is extended as showna't 38" and has its end portions bent to provide a le-ver arm 41 u Jon which will be mounted a weight 42. by having this position.

lever arm and weight, the weight will serve to normally hold the blades in the closed position. These blades have a construction similar to the slats of a window shutter and it will be readily seen that although the blades are normally held in a closedposition by the weight 42, movement of the lever arm against the action of this weight will serve to move the blades or vanes to an open or inoperative position. v

In order to permit of the blades being moved to an open or inoperative position when desired, to prevent operation of the windmill, there has been provided rocker shafts 43 which are mounted by means of bearings 44:. Each'of these rocker shafts is provided at its inner end with a depending handle element .5 and at its outer end is provided with an offset arm/i6 extending for engagement with the lever arms d1 when the rocker shafts are rotated to swing the arms 46 upwardly. In order to rotate the rocker shafts and swing the arms 46 upwardly there has been provided a disk 47 which is slidably mounted upon the bearing 10 and is provided with depending arms'etS which extend through openings formed in the head 3 and have their lower ends pivotally connected with the arms of a V-shaped lever 49. This lever 49 has its arms pivotally connected with bearings 50 carried by one of the cross bars 2 of the tower and has its outer end portions provided with an. eye 51 so that a pull line 52 may be connected with this lever. It will'be readily seen that. when the pull line 52 is drawn upon by a personv standing at the foot of the tower, the lever 49 will be rocked uponthe bearings 50 and the arms 48 and disk 47 will be moved upwardly. As the disk 47 moves upwardly,

the rocker. shaft 4C3 will be rotated and the arms 46 swung upwardly to engage the lever arm 41 and turn the bladesB'T to an inoperative position so that the wind will not have to begradually opened as-the wind increases in force beyond an amount which it would be safe to have the blades in the closed Therefore, there has i been provided pendulum arms 53'wl'iichare pivotally connected with the carrier and are provided with weights 5% at their lower, ends. Side arms extend from the pivotally mounted upper ends of the pendulum arms and extend. into positions to engage the arms d6 when the arms are swung upwardly. As the carrier turns with the rotating hollow shaft ll, centrifugal force will be set up the speed increases and the pendulums will swing outwardly? When the peiidulums have swung: outwardly a suflicient distance to bring the side arms 55 into engagement with the arms 46, the arms l.(i \\"lll be swunp upwardly and will engage the lever arms 41.

the carrier and hollow shaft.

creases in force, the blades will be turned to- Ward the open or inoperative position and less surface will be presented for the wind to act upon. hen the blades are completely moved to an open position, th operation of the wind mill will be shut off the same as when these blades are moved to the open or inoperative position by means of the disk 47 being brought intoengag'ement with the arm 45.

-When this wind mill is inoperation, the elements will be in the position shown in Fig. 1 with the blades shut. When the wind st-rikesthe wings which extend downwardly.

it will tend to impart rotary movement to \Vheu thesecond wing has swung into position forengagement by the wind, this wing which has been positioned substantially horizontally but slightly inclined downwardly will be struckby thewind and will be swung down 'wardly to a. substantially vertical position. At the same time, the first wing will be swung to the horizontalposition. It will thus be seen that as the w ngs swung into and out of the horizontal and. vertical positions,

rocking movement will be imparted to the rocker shafts and at the same time rotary movement imparted to the shaft 11 and carrier. The rocker shaft is connected with the 'shaft 8 by means of the link or pitman 22 and therefore this shaft 8 will rotate with the shaft 11 but at the same time rocking shaft 8 isconnected with the pump rod 6 by means of the swivel connection 9 and therefore the pump rod 6 willonly receive reciprocating. movement so that the pump will be properly operated. Itwill thus be i seen that by means of this wind mill. rc-

ciprocating movement may be imparted to the pump. 5 to operate the same and at the same time rotary movement may be transmitted from the hollow shaft 11 by means of the belt 14. lVhen'it is desiredto prevent further operation of the wind mill. it is simply necessary to draw upon the pull line 553 and the "disk 47 will be moved upwardly to engage'the' arms 45 and turn the rocker shafts 43" to swing the lever extensions or lever arn'is il upwardly and thus open the shutters so that the wind cannot operate which is very effective in operation and easy to control; J
