Specification of Letters Patent.
Patented Feb. 23 1915 Application filed February 4, 1914. Serial No. 816,428.
To all whom it may concern:
Be it known that I, SAMUEL G. BARR, a citizen of the United States, residing at Laredo, in the county of Grundy and State of Missouri, have invented new and useful Improvements in lVindmills, of which the following is a specification.
This invention relates to wind mills and it consists in the novel features hereinafter described and claimed.
An object of the invention isto provide a wind mill of simple structure and which includes a tower having a shaft journaled therein and provided with a series of blades at its upper end. A shield partially incloses the set of blades and an arm is connected with the shield and is arranged to rotate about the axis of the shaft. A vane is carried by the arm and means provided for securing the arm at an adjusted position upon the tower. The parts are so arranged that the shield may be disposed so as to cause the set of blades to rotate in either of two directions or the said shield may be interposed between the wind and the set of blades whereby the set of blades will remain at a state of rest.
In the accompanying drawings :Figure 1 is a side elevation of the mill. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view of an arm and attached parts used upon the mill. Fig. 4 is a detailed section view of one form of retaining bolt mechanism used upon the mill. Fig. 5 is a detailed sectional view of the lower portion of the mill. Fig. 6 is a perspective view of a -modified arrangement ofthe parts of the mill.
The mill comprises a tower 1 which may be of any suitable structure and a vertically disposed shaft 2 is journaled for rotation in the tower. A gear wheel 3 is fixed to the lower portion of the shaft 2 and may be employed for transmitting movement from the said shaft to machines or devices which are operated by the mill. The shaft 2 is provided at its upper end and above the upper end of the tower 1 with a series of blades or vanes 4. An arm 5 is journaled upon the upper portion of the shaft 2 below the vanes 4 and above the upper end of the tower 1 and carries a shield 6 which partially incloses the set of blades 4. The arm 5 is provided at that end opposite the end thereof at which the shield 6 is located with a vertically disposed vane 7.
An arcuate guide 8 is mounted at the upper end portion of the tower 1 and the arm 5 is provided with a bracket 9, as shown in Figs. 1, 3 and 4, which extends under the lower portion of the said guide 8. The gulde 8 is provided at intervals With perforations 10. bracket 9 and a bolt 12 is slidably mounted 1n the case. A stop 13 is mounted on the bolt 12 between the ends of the case 11 and a coiled spring 14 bears at one end against the end of the case and at the other end against the stop 13. The said spring is un der tension with a tendency to hold the end of the bolt 12 toward the guide 8. The bolt 12 is also provided at one end with an eye 15 with which a rope or cable 16 is connected.
The operation of the mill is as follows: By grasping the cable 16 and drawing in a downward direction upon the same the bolt 12 may be moved out of contact with the guide 8 and by using the rope 16 the arm 5 may be swung upon its pivotal connection with the shaft 2 so that the shield 6 may be brought between the wind and the blades 4. Then by releasing the rope 16 tension of the spring 14 comes into play and the bolt is moved longitudinally whereby the end of the said bolt is caused to enter one of the perforations 10 in the guide 8 and the parts are held at the adjusted positions. When the shield 6 is interposed between the wind and blades 4 the said blades will remain at rest. By using the cable 16 and swinging the arm 5 so that the blades 4 at one side of the axis of the shaft 2 will be exposed to the wind the said shaft 2 will be rotated by the force of the wind in one direction. By using the cable 16 and swinging the arm 5 in an opposite direction so that the blades 4 at the opposite side of the axis of the shaft 2 are exposed to the wind the said shaft 2 will be rotated in an opposite direction. Therefore it will be seen that by using the arm and the shield mounted thereon the shaft may be caused to remain at a state of rest or may be caused to rotate in either of two directions. The vane 7 provided at the outer end of the arm will be acted upon by the wind and will promptly cause the arm 5 and shield 6 to assume such positions with relation to the blade 4 as to cause them to come to a state of rest promptly when the bolt 12 is disengaged from one of the perforations 10 in the guide 8.
A case 11 is carried by the I In the form of the invention as shown in Fig. 6, a spring pressed bolt 18 is slidably mounted under the arm 5 and extends parallel therewith. The said bolt is adapted to engage notches 19 provided in the edge of the guide 8. A pulley 20 is mounted upon the arm 5 and cables 21 are trained over the pulley 20 and are attached at one end to the end of the bolt 18. The said cables are then trained over the pulley 22 journaled under the guide 8. It is apparent that by drawing on oneof the cables 21 the bolt 18 Will first be withdrawn from that notch 19 in which it is engaged and the arm 5 will then swing toward that pulley 22 over which the said cable is trained.
Having described the invention what is claimed as new is A wind mill comprising a tower, a shaft journaled therein and provided at its upper end with a series of blades, an arcuate guide mounted upon the tower below the set of blades, an arm journaled upon the shaft above the guide and below the blades and extending transversely across the guide and carrying at its outer end a vane, a wind shield mounted upon the inner end of the arm and partially inclosing the set of blades, a bracket carried by the arm, a case carried by the bracket, a spring pressed bolt slidably mounted in the case and adapted to engage the guide and a cable connected. with the bolt.
In testimony whereof I afiix my signature in presence of two witnesses.
