. This invention relates to wind mills, particularly to those ofthe horizontal type, and has for its object the provision of a wind mill provided with a plurality of revoluble vanes, the position of the vanes being automatically varied during the rotation of the wheel whereby the maximum degree of rotative power of the wind impinging against the vanes will be obtained. An important object is the provision of a device of this character in which vthe positions of the vanes will be varied properly to obtain theomaximum power regardless of the direction in which the wind is blowing, the vane shifting meansbeing automatically regulating in accordance with the direction of the wind.

Another object is the provision of a device of this character provided with manually operated means may be varied so that the vanes will be antomatically moved into a-position parallel with the wind and therefore eventually bringing the device to a stop, this shifting the movement of the wheel.

Still another object is the provision of a device of this character provided with means whereby the entire device maybe thrown into its inoperative position.

An additional object is the provision of a device of this character which will be comparatively inexpensive inmanufacture, efficient and durable in service, and a general the art.

With these and other objects and advantages in view, the invention consists in the novel construction and arrangement of parts as will be hereinafter more fully described and claimed and illustrated in the acc0mpanying drawing, in which V I Figure 1 is a top plan view of my device, Fig. 2 is a vertical sectional view therethrough, Fig. 3 is an enlarged vertical sectional view through the head, showing the Dominion of Canada, have invented whereby the adjustment device inits operative position, Fig. 4 is a similar view showing the parts moved to throw the device into its inoperative position, Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 2 looking upwardly, Fig. 6 is a cross sectional view, looking downwardly, on the line 66 of Fig. 2, and

Fig. 7 is a detail sectional view through one of the shiftable collars.

Referring more particularly to the drawing, the numeral 10 designates the supporting tower upon which my device is mounted and which may be of any desired height.

The tower 10 is formed preferably of a plurality of angle bars 11 of any desired cross section which converge toward their upper ends in the usual manner and are connected with a tubular head 12 which may be slotted at its lower end as shown at 13. Adjacent the upper portion of the tower 10 are rings 14 grooved upon their upper edges as shown for a purpose to be described.

My novel wind mill comprises a wheel formed of upper and lower horizontal bars 15 and 16 which have their ends connected and braced by suitable wires as shown. The bars 15 and 16 are connected by substantially vertical bars 17 and brace'd by diagonal bars 18 connecting the bars 15 and 17. The bars 15, 16, 17 and 18 form a frame and there are preferably six of these frames comprising the wheel, the frames being connected at their rings 19 and 20, the lower faces of the rings 20 being grooved as shown and coiiperating withthe grooved rings 14 on the tower to form races for the reception of balls 21, or rollers if preferred. By. this structure it will be seen that the wheel is freely and easily revoluble relatively to the tower.

In order that the wheel may be rotated by the action of the wind, I provide a pluper ends 24 and the lower ends 23 of which lower and upper ends by.

are respectively journaled in the upper and lower bars 15 and 16 of the wheel frame, fixedly engaged on the shafts above the bars 15 with worm wheels 25. Journaled through bearings 26 secured upon the upper bars 15 are shafts 27, corresponding in num her to. the number of vanes and carrying upontheir outer ends worms 28 which mesh with the worm wheels 25. The extreme inner ends of the'shafts 27 have loosely mounted thereon beveled pinions 29 which are prevented from longitudinal movement by collars 30. Adjacent their ends, the shafts 27 have loosely mounted thereon larger beveled pinions 31, which are prevented from longitudinal movement upon the shafts 27 by stop collars-32 l The" automatic controlling portion of my device comprises a head33 disposed upon the standard head 12 and provided with overhanging flanges for holding it in position. The head 33 is in the form-of a sleeve having inner and outer gears 35 and 36 formed thereon and meshing respectively with the pinions 29 and 31. the upper portion of the head is a bracket 37 upon which are formed hooks '38- journally receiving arms 39 secured upon a tail 40. 4

In order'that the tail 40 may be moved, I provide a pulley 41 journaled upon the bracket 37 and having trained thereover a cord or cable42 connected with the tail as shown 43 and; extending downwardly through the head 12' to the bottom of the tower. 7

Splined upon each of the shafts 27 between the pinions 29 and 31 is a flanged collar 44. which carries upon its sides bolts 45 and 46 slidable within recesses and normally pressed outwardly by coil springs 47, the bolts being prevented from moving entirely out of the recesses by pins 48 passing through" slots 49. The pins 45 and 46 are adapted to engage withinholes 50 and 51 in the opposed faces of the pinions 29 and 31 respectively. Under normal conditions,

when the device is in operation, the pins 45 are in engagement within the holes 50 111 the pinions 29, thus locking the pinions 29 upon the shaft 27. V V The holes 50 in the pinions 29 are so arranged that when they are engaged by the bolts the shafts 21 will be so held relatively to each other that the vanes 22 will be disposed relatively to each other, as shown in Fig. 1. As the wind impinges against the vanes, the wheel carrying the vanes will rotate and by virtue of the meshing of the pinions 29 with the gear 35 the vanes will be turned continuously as the wheel rotates, the worms 28 and worm wheels 25, so that the vanes will always be disposed at'the proper angle for obtaining the maximum power from the wind. The gear 35, pinions 29, worms 28 and worm wheels 25 are soproportioned that as the wheel makes one complete revolution each vane will be turned through half a revolution.

ssuming that the wind has been blowing in a certain direction, and then suddenly changes, the tail 40 will move so as to be parallel with the wind. As the tail i moves, the head 33 upon which it is mounted will also move, resulting in movement of the gears 35 and36. This movement of the new direction as they presented to Formed upon will always be disposed parallel with the wind, I provide a lever 52 pivoted at 53 upon one of the uprights forming the tower and having a rope 54 connected with one end thereof and leading down to the ground.

a rod 55which extends upwardly and ter To the other end of the lever 1 52 is connected minates in a fork 56 disposed within the slot 13 in the tower head 12. The fork 5.6 supports a ring 57 which contacts with the inher ends of the horizontal levers 59 pivoted at 60 upon the bars 15 and having their vertical arms 61 forked and engaging the'fianged collars 44. When it is desired to swing the vanes parallelarms 58 0f angle with the wind, it is merely necessaryto rock the outer end of the lever 52 downwardly, as by means of the rope 54, whereupon the rod 55 will be movedrupwardly carrying the plate -or rin 57. Upward movement of the ring 57 will tical arms 58 of the angle levers 59 outwardly, thus disengaging the-bolts 45 from the holes 50, by reason of the fact that the flanged collars 44 are moved outwardly upon the shafts 27. 46 to bear against the inner faces of the pinions 31, and as the pinions 31 rotate, the pins or bolts 46 will slip into the holes 51 when they register rock the ver- Y This will cause the bolts 1 therewith. As the bolts 2 46 engage within the holes 51, the pinions 31 will be locked upon androtate with the shafts 27 and consequently as the wheel rotates, owing to the proportionate sizes of the gear 36, pinions 31, worms 28 and worm wheels 25, the vanes 22 will be rotated, only i in the event of a sufliciently strong wind to break the device, the device may be quickly and easily rendered inoperative so that "the force of the wind can have no purchase upon v the vanes.

In case it is desiredto stop the wheel gradually or altogether, when the wind is not blowing too severely, it is merely necessary to pull upon the cable 42 whereupon the tail 40 will move into such a position that its relation to the vanes will be such that the vanes will gradually be disposed in similar positions to the wind on each side of the tail, owing to the engagement of the gear with the pinions 29. This is done only when the device is in its operative position and not when the mill has been adjusted in the event of a hurricane.

In order that the power derived from the rotation of the wheel may be utilized, I provide an internal gear 62, secured upon the bars 17 of the wheel frame between the rings 20 and meshing with a pinion 63 secured upon the end ofa shaft 64 extending downwardly along the tower 10. and journaled through suitable bearings 65.

It will be readily understood that I reserve the right to make various changes in the form, construction and arrangement of parts without departing from the spirit of the invention or limiting the scope of the subjoined claims.

,Having thus described my invention, I
