FEATHERING PADnLE-WHEELS. No.184,532. Patented Nov.z1,1e7e.
UNITED STATES PATENT GFEICE.
FRANCIS J. LEISEN, OF WOODBRIDGE, NEW JERSEY.
IMPROVEMENT IN FEATHERING PADDLE-WHEELS.
Specification forming part of Letters Patent No. 184,532, dated November 21, 1876 application filed May 22, 1876.
To all fwhom it may concern Be it known that I, FRANCIS JOSEPH LEI- SEN, of Woodbridge, in the county of Middlesex and State of N ew Jersey, have invented a new and improved Feathering Paddle-Wheel, of wh ich the following is a specication:
My improvement in feathering paddlewheels consists of a contrivance of stationary cams in a hollow hub, in which the bucketarms are fitted in boxes so as to revolve a quarter of a revolution forward and backward to present the buckets sidewise or edgewise, the essential feature of the invention being the contrivance of the hub.
Figure l is a sectional elevation of the wheel on theline .x a: of Fig. 2. Fig. 2 is a horizontal section. Fig. 3 -is a perspective view of one of the paddles. Fig. 4 is a side elevation of one of the parts of the hub, and Fig. 5 is a section through one of the paddlearms and its box.
A and B represent two parts of a hub joined together in the plane of the wheel, and fitted to turn on' a stationary shaft, C, in the center of' which hub is a grooved stationary h ub, D,
. containing cams E and F for turning the paddle-arms forward and backward by acting on the heads H and I of the inner end of the paddle-arms. The part A of the hub has recesses in one side to receive journal bearings or boxes K of brass or suitable metal for the arms to turn in, said boxes being made in two parts and rabbeted at the meeting-faces so as to be suitably confined against lateral play,
`the water by acting on the heads El, and the cam F turns them edgewise by acting on the headsI.
Having thus described myinvention, whatI claim as new, and desire to secure by Letters Patent, is-
1. 'IheA combination, with the hollow hubA B, containing stationary hub D, having cams E Land F,-of the paddle-arms G, having heads- H and I, substantially as specified.
2. The part A of the hub having recesses in the side for the boxes K, and the part B having radial sections L, combined and arranged substantially as specified.
