SPEJIFICATION forming part of Letters Patent No. 789,4:97, dated May 9. 1905.
Application filed January 30, 1905. Serial No. 243,246.
To a. who/1t it may concern:
Be it known that l, ALFRED (l. JonNsoN, a citizen of the United States, residing at VVinters, in the county of Yolo and State of California, have invented new and useful Improvements in \Vindmills, of which the following is a specification.
My invention relates to improvements in windmills; and it consists in means for positioning the mill with relation to the wind, means for transmission of power from the wind-wheel, and the construction of the wheel, the tower, and intermediate supporting devices.
The invention comprises combinations of parts and details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a transverse section of my invention. Fig. 2 is a plan view of same. Fig. 3 is a view of Wind-wheel. Fig. 4 is a view of Worm-wheel and rack. Fig. 5 is a view of regulating-wheel. Fig. 6 is a view showing method of supporting vanes.
It is the object of my invention to provide a wind-propelled wheel so constructed that the most effective exterior portions of the vanes of the wheel are available Without the weight of a comparative valueless center. A skeleton tower is also so constructed as to allow of a free passage of the air through it, so that the wheel being journaled upon the top of the tower the lower half is exposed to the action of the wind.
Means are provided for revolving the wheel and its bearings within the tower and means for transmitting the motion of the wheel to a centrally journaled universally adjustable mechanism through which power may be transmitted to fixed appa 'atus.
As shown in the drawings, the tower is com posed of angle-iron bars A, which are made of the smallest possible area for strength. These bars are united by similar and horizontally-disposed angleirons 2, fixed to the vertical posts at intervals and forming a substantially cylindrical structure, and the whole is again strengthened by trausversely-disposed slender rods or wires 3, drawn to the required tension for rigidity. This forms a structure which allows the wind to pass through it almost entirely unimpeded, and I am thus enabled to journal a wind wheel at of large diameter upon the top circular ring of the tower, so that one half only of the wheel appears above thetower, the other half turning within it, but being fully exposed to the action of the wind.
The shaft 5 of the wheel extends entirely across from side to side. and its journal-boxes 6 are supported upon frames or yokes 7, having rollers 8, which are adapted to travel upon the top rim of the tower. This rim is prefcrably made of angleiron, and its outer periphery may be toothed, shown at 9.
The wind-wheel consists of suitably-formed radially-disposed vanes having light concentric rings upon each side of the vanes at intervals between the outer and inner ends, and these rings are braced from one to the other With diagonally-disposed bracing-bars. the angle of which bars is such as to coincide with and support the vanes in their angular position. This structure is Well shown at 10. As the inner portion of the vanes would have little or no propelling power on account of their narrowness and on account of their proximity to the axis, 1 have shown the inner supportingring of large diameter and the whole wheel supported at a considerable distance outside of its axis by tension wires 11, stretched from either side of the wheel to the sleeve 12, which forms the axis, and is turnable upon the shaft which extends across the tower. The wheel is thus practically sus pended around the shaft with its periphery turning in close proximity to the upper rim of the tower.
The ends of the shaft 5, exterior to the journalboxes, have worms upon them, and these engage with gear-wheels 13, which are journaled upon the yoke or frame which carries the journal-boxes of the shaft. Upon the lower ends of the shafts of these gear-wheels are pinions it, which engage the teeth around the rim of the tower. As the gear-wheels and pinions are so disposed that one may turn in one direction and the other in the opposite direction, it will be seen that by thus turning the pinions the shaft will be gradually turned around upon the top of the tower, one end moving in one direction and the other in the opposite direction, so that the wheel may always be placed in the desired position to receive the full power of the wind or to be turned out of the wind, as required, and this travel of the shaft around the common center will maintain the wheel in its proper position within the tower. In order to thus operate this turning-gear, I have shown the shaft extended beyond the worm or screw at one end and having upon the outer end a bevel or crown gear 15. This is engaged by a pinion 16 upon the vertically-supported shaft, and upon the same shaft is a gear-wheel 17, which engages with a pinion 18, mounted upon the shaft 19 of a small wind-wheel 20. This wind wheel and its shaft is turnable about the vertical axis of the gear-wheel 17 and may thus be thrown into or out of the wind. If thrown into the wind, its action will turn the mainwheel shaft 5 and thus acting through the sleeve carrying the main wind-wheel will simultaneously turn the worm-gears at opposite ends and will thus turn the main wheel with relation to the direction of the wind, as previously described. hen the proper or desired position has been reached, it is only necessary to throw the small wheel out of the wind and the main wheel will remain in the position to which it has been set, either so as to receive the wind or be thrown out of the wind.
In order to transmit the motion and power of the main wheel and to make it possible to do so whatever may be the position of the wheel, I have shown a platform 22, is suspended by light rods 2-3 from the yokes or frames which carry the wind-wheel shaft journals, so that whatever change of position of the wheel may take place will be transmitted to the platform, which will move in unison therewith. Upon the rim of the wind-wheel is fixeda light pulley 25. Upon the platform is journaled a vertical shaft 26, carrying a pulley 27 upon the upper end, and parallel with this shaft is another shaft 28, having a pulley 29 lying in the same plane with the pulley 27.
30 represents angularlysupported direction-pulleys, and the driving-cord 31, passing around the main-wheel pulley, passes thence around one of the angularly-journaled direction-pulleys, thence successively around the two horizontal pulleys, as shown, thence from the other angular pulley to the main pulley, so that power will be transmitted to the vertical shaft 26, which is located centrally of the tower and in a line passing through the plane of the wind-wheel and its axis. From the shaft 26 power may be transmitted by any suitable or desired connections, depending upon the work to be done.
The shaft of the pulley 29 is journaled in a fork or yoke, so as to be movable to or from the pulley 27, and by means of a weight 32 and and this a cord passing over a pulley 33 and connecting said weight with the yoke in which the wheel 29 is journaled the latter may always be moved outwardly, so as to insure a proper tension upon the driving-belt.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1.
