IMPROVEMENT IN WINDMILLS.
Specification forming part of Letters Patent No. 124,282, dated March 5,1872.
SPECIFICATION.
I, WILLIAM D. NICIIoLs, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in W'indmills, of which the following is a specification, reference being had to the accompanyin g drawing.
The Object and Nature of my Intention.
My invention relates to making a windmill with two sets of rosette sails, arranged so that they will be on opposite sides of the mill at all times; the object being to make a balanced mill and a mill of large capacity without making as large rosette sails as has been necessary heretofore; and also so arranging the sets of sails on the shaft that one of them takes the place of the vane ordinarily used to keep the mill to the wind. By using two sets of rosette sails so that they balance each other on the machine, I can use much smaller rosette sails to obtain a given capacity; consequently a lighter mill, and one much more durable and less liable to accidents.
Description of the Drawing.
Figure 1 represents atop or plan view of my improved windmill; and Fig. 2, a side elevation, with a piece broken out of the bearing or support S, to show the interior.
General Description.
cast upon the hub C and connected by the bridge E. The shaft F has bearings on the supports D, and has a set of rosette sails, S, on each end. These sets of sails may be constructed in any of the known methods of con structin g what is called rosette sails for windmills. The particular kind of rosette sails shown in this application for a patent, are the same as are shown and fully described in my application for a patent for improvement in windmills, filed by me in the Patent- Oflice, December-1, 1869, and allowed January 19, 1870.
It will be observed that both sets of rosette sails S are so attached to the shaft F that the corresponding sides are in the same direction. I do not limit myself to this construction and arrangement of sails and their connections, for any known kind can be used.
H is the lever for throwing the rosette sails into and out of the wind, and I is the vibrating rod, communicating power from the shaft F by means of the eccentric J. I usually make one of the sets of sails larger than the other, which serves to keep the sails turned to the wind; but in order that there may be no chance for failure, the vanes V are used. They are supported upon the arms L, and may be braced in any suitable manner. They are so attached as to always turn the largest set of sails behind the other set, as shown in Fig. 2.
Claim.
What I claim, and desire to secure by Letters Patent, is-
I claim the two sets of rosette sails S S, when combined in a windmill so as to balance each other,,substantia1ly as and for the purposes specified.
