LEWIS A. BOSWELL, OF TALLADEGA, ALABAMA.
IMPROVEMENT lN AERIAL PROPELLER-WHEELS.
Specification forming part of Letters Patent No. 155,218, dated September 22, 1874; application tiled April 4, 1874.
To all whom it may concern:
Be it known that I, Dr. LEWIS A. BOSWELL, of Talladega, in the county of Talladega and State of Alabama, have invented a new and Improved Aerial Propeller-Wheel, of which the following is a specification:
My invention consists of an aerial propellerwheel in which the fans or vanes are mounted horizontally on a hub of a vertical axis, so as to revolve on their own axes independently of each other, and they have an arm or projection which moves against a stationary cam and turns the vanes edgewise to the wind at the time of beginning the return movement, so as to offer little or no resistance while going backward, and a spring and chain are combined with each vane-arm in such manner as to turn the vane back so as to take the wind when the vane begins the forward movement at the moment the arm escapes from the cam.
Figure l is a plan view of an aerial propeller with wheels constructed according to my invention. Fig. 2 is a transverse section.
Similar letters of reference indicate correspondin g parts.
A represents the vanes; B, the vane-arms; O, the rim; and D, the hub of the middle portion of the wheel, on which they are mounted in bearings E, so as to revolve freely. F represents the lateral arms on the vane-arms G,
stationary arms for turning the vane-arms out of the wind; H, the spring, and I the chain mounted on the wheel and connected to the arm of a vane, so that the chain is wound on and draws the spring when the vane turns out of the wind, when its arm F comes to point L to turn it back by the tension of the spring, when the arm E escapes from cam G, which occurs when the vane arrives at the point K, where it begins the backward movement, all of which will be understood by inspection of Fig. 1. The wheels are mounted on a vertical shaft, J, which gears with a drivingshaft, H, to be driven by any suitable power.
Thus it will be seen that the vanes can be run with direct action against the wind and without material resistance when returning rear to front.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The vanes, arranged to revolve on their axes in the hub of the wheel, and provided with an arm, E, chain I, spring H, in combination with a stationary cam, G, substantially as specified.
