Application filed November 3, 1902. Serial No. 130,008. (No model.)

To all whom, it may concern,.-

Be it known that l, ALPHoNsUs M. ORUNI- GAN, a subject of the King of Great Britain, and a resident of London township, in the county of Middlesex, in the Province of'Ontario, Canada, have invented a new and useful Air-Motor or Windmill, of which the followi-ng is a specification.

This invention relates to a device by which motion is imparted to mechanism for pumping water, churning, grinding grain, and for many other purposes by the action of the wind on a series of laterally-pivoted radiating fan-blades; and it consists of the improved construction and novel combination of parts,

as will be hereinafter described, reference being had to the accompanying drawings, where- V Figure 1 is a front view of an air-motor or windmill embodying my invention. Fig.V 2- is an enlarged detail central vertical sectional view of they gearing and of the vertically-adjustable sleeve on which it is mounted. AIn this view a central verticalsectional view of a portion of the main mast-on which said sleeve f is vertically adjustable is also shown. Fig. 3

Fig." 1i

the sliding collar which operates the mechanism to throw the wind-wheel in or out of operation, and the sleeve on which said collar is adjust'ably supported and a side view of the shaft on which said wind-wheel is fixed and of the support of said shaft and its connections with the gearing'on the vertically-adjustable sleeve. Fig. 13 is an enlarged detail perspective view of the sliding collar shown Fig. 12, together with its operating mechanism. Fig. 14 is an enlarged detail plan view ing at a rate of speed in excess of that necessary to operate the wind-wheel. Fig. 17 is --an enlarged detail side view of the brake andy brake-rod and a sectional View of a portion of the vertically-adjustable sleeve.

In the accompanying drawings the numeral 1 designates a mast formed` of av beam of H- shaped steel; but it mayloe formed of any other suitable shape or material desired. The lower end of said mast 1 'is inserted and secured in a bed of concrete 2, and its upper end is braced by the stayorbrace' wires 3, eX- tending from the outer ends of the cross-arms 4 to the anchors 5 in the ground. Said mast 1 is thus rigidly supported land'h'eld in an upright position, both -above and below the operative parts, thereby making it very solid,

and'said 'cross-'arms 4 are rigidly secured to i;tend from said mast 1 out beyond said operative parts in order that the operation of the latter may not be. interfered withby said stay or Ybrace wires. `"6 designates asleeve which encircles anfdfatthesame time is'adapted" to be freely adjusted vertically on said mast 1. 7 is a chain secured at one end to` said sleeve 6, which chain extends over a grooved pulley 8, supportedinbearings near the upper end of the mast 1. Said chain 7 then extends downward and is secured to the counterbalance-Weight 9, and said counterbalance-weight is located out of the way between the fianges of the mast 1 and is adapted to balance the sleeve 6 and the gearing mounted thereon. As a result the raising or lowering of said sleeve 6 and attachments is facilitated.

111 is a guiding and connecting rod which extends through holes in-the upper and lower annular rings 21 and 27, and said rod 111 is connected at its lower end to the band 108, and its upper end is connected by the coupling-link 112 to the pivotal vane-arm 113, pivoted on the bracket 114, and vto the outer end of said arm 113 the small vane 115 is secured Yat about right angles to the large vane 91, so that when the large vane 91 is feathering the wind the small vane 115 will be against the windl 1'16 designates a bolt which extends through the pivotal vane-'arm113, and its lower end is secured to the bracket 114, and 117 is a coilspring which encircles said bolt 116 between the enlarged head thereof and said pivotal vane-arm 113.

The operation is as follows: By winding the chain 18 around or unwinding it from the drum 13 the vertically-adjustable sleeve 6, together with the gearing mounted thereon and the wind-wheel, may be raised or lowered to work at any place on the mast 1 from the ground to the cross-arms 4; and by means of the counterbalance-weight 9, crank 16, and gear connected therewith said sleeve 6 and attachments may be adjusted near the ground for the purpose of oiling, or to be out of the Way of storms, or to be adjusted to catch a current of air at any elevation on the mast 1. As a result the oiling is accomplished with ease and with perfect safety to the operator and is very likely to-be attended to more regularly, and when the direction of the wind changes and said wind strikes the vane 91 from the opposite side to that at which the parts 94 to 98 are situated the dog 94 rides on the teeth of the annular toothed flange 26, and again when the direction of the wind changes and said wind strikes the vane 91 on the same side as that on which the parts 94 to 98 are situated the arm 90 swings slightly on the pivot-bolt 33. This acts on the rod 95 to disengage the dog 94 from the teeth of the annular toothed flange 26 and permits the vane 91 to adjust the wheel to the wind, and the instant that the wheel is adjusted to the wind the force of the wind is removed from the side of the vane, the vane-arm moves back to its normal position, and the dog 94 again engages with the teeth of the annular toothed fiange 26, and the excessive movement pivotally of said arm 90 on the pivotbolt 33 is limited by the bar 92 abutting against the nuts 34 on the bolts 33adjacent to the ends of said bar 92, so that when the wind is blowing in 'one direction and Athe vane has adjusted the wheel to the wind the parts 94 to 98 lock the annular ring 27 with the collar 24 on the sleeve 6 to prevent the gear from acting on the sleeve 6 to cause the latter to bind on the mast. At the same time when the direction of the wind changes the parts 94 to 98 permit the vane to adjust the wheel to the changed directionmof the wind, and the beveled gear -pinion 45, being secured to the shaft 43, supported by the standard 29, it engages with the beveled gear-wheel 42 at Whatever point the large vane 91 and parts connected therewith may be adjusted to by the wind. Again, the beveled gear-wheel 42 and internal gear-wheel 41 being supported by ring 38 and rotating independently of the sleeve 6 and the annular rings 21 and 27 and attachments and said internal gear-wheel 41 engagingl with the gear-pinion 52, as the windwheel revolves, said beveled gear-pinion 45, beveled gear-wheel 42, internal gear-wheel41, gear-pinion 52, and shaft 46 are rotated, as well as the beveled gear-wheels 50 and 87, shaft 85, and chain-wheel 88, secured to said shaft 85, from which chain-wheel motion is communicated by achain beltto the pump, churn, or any machinery requiring to be operated, and the spindles 53, to which the gear-pinion 52 is secured, being vertically adjustable on the shaft 46, the latter is operated at whatever elevation the sleeve 6 and attachments may be adjusted to on said mast 1. By securing the weight 80 to the lower end of the rope 79 the band 77, the guiding-rod 82, and the adjacent arm ofthe lever 73 will be lowered and the coil-spring 84 compressed. This will draw the upper end of the lever 73, the adjustable collar 65, and lower end of the lever 67 toward the standard 29 and adjust the upper end of the lever 67 outward to operate the bell-crank lever 69, ring 63, and cranks 61 on the ends of the radial rods 60 to bring the side of the fan-blades 64 to the wind to rotate the wind-wheel and start the mill to work, and when said weight is removed, said fanblades having a greater area on one side of said radial rods, as hereinbefore described, the current of air has the greatest effect on the side having the greatest area. As a result the blades are automatically adjusted by the current of air to feather the latter, and they remain so until it is wished to start the mill to work, which is done at once by securing the weight to the lower end of the rope 79, when the parts connected therewith will be operated as hereinbefore described and the machine started to work.

When using the eccentric brake 104, the dog 17 may be disengaged from the toothed wheel 14, and when so adjusted the eccentric brake 104 holds the vertically-adjustable sleeve 6 and attachments from accidentally lowering or being lowered. When so adjusted, if a windstorm of great force was to strike the mill it would force the inclined small vane 115 backward and downward and lower the vane end of the pivotal vane-arm 113. This would raise the opposite end of the vane-arm 113, the connecting-rod 111, band 108, slide 109, and draw upward on the rope 110 to raise the outer end or handle n of the eccentric brake 104 and disengage it from the brake-rod 99, when the action of the wind on the fan-blades 64 would be to lower the wind-wheel, sleeve 6, and attachments on the mast 1 near to the ground and out of the wind. Thus all running away of the mill or damage or injury therefrom is avoided and completely prevented. As a result a simple, strong, durable, inexpensive, and light and easy-running air-motor or windmill is provided; one in which asingle IOO mast is used instead of a tower; one in which the gearing may be easily lowered to oil, and thus do away with the necessity of the oiler climbing up to the top of the machine and exposing himself to danger from falling; one in which the wind-wheel may be raised or lowered with ease to any elevation to catch a current of air at any elevation on the mast 1; one which is so constructed that the lgearing and'windwheel will be automatical-ly lowered out of danger at the beginning of'storms of excess- 4ively high'wind, and one in which the raising and lowering of the sleeve and gearing and wind-wheel mounted thereon may take place at the same time as the wind-wheel is revolving on its axis to communicate motion to the gearing which rotates the vertical operating-shaft 46, and both of these operations may be taking place while -the vane 91 is being adjusted by the wind to move the annular rings 21 and 27 and Wind-wheel around the sleeve 6 to maintain the fan-blades against and in proper position to be acted upon by the wind.
