PROPELLER FOR CANAL-BOATS.
Specification of Letters Patent No. 20,862, dated July 13, 1858.
i and State of New York, have invented certain Improvements Relating to the Construction and Propulsion of Canal-Boats; and I do hereby declare that the following is a full and exact description thereof, reference being made to the accompanying drawings and to the letters of reference marked thereon.
T he nat-ure of my invention relates 1st to a propeller shaft so constructed and arranged that it may be moved in a. longitudinal direction any distance from one to live feet (more or less) and support the propeller on the end thereof, so that the propeller may be projected outwardly, to get a good hold upon the water, and drawn inwardly toward the boat and close up to, or under the stern, when passing locks, Sac.; 2d, in Vconstructing the rudder with a notch or recess therein of sufficient size to receive the propeller and allow it to work therein, and so that the rudder will swing clear, of the propeller, and at the same time guard and protect the propeller.
To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.
Figure I, is a longitudinal section of the boat showing in elevation the construction and arrangement, of the rudder propeller, and propeller shaft. Fig. II, is a cross section of the propeller shaft.
A, represents the rudder. It is constructed so as to make a notch or recess in the part neXt to the boat, and so that it will swing over and beyond the propeller. It is connected to the tiller post (E,) the tiller post being also made fast to the stern, by means of two hinge joints, as shown at b o. Its whole width is about eight and one half feet. This allows of a notch or recess of about live feet next to the boat, so that the propeller may have a horizontal movement (to and fro) of from one to five feet, without coming in contact with the rudder. This will leave the rudder about three and one half feet wide in all its parts outwardly from the recess, with a longitudinal width of about eight feet above the propeller. A bar of iron (c) is made fast to the lower end of the rudder, which bar is hinged to a projection from the keel, as represented at d. This joint (d) is on a line with the tiller posts and joints Z) b. It will be noticed that this construction and arrangement of the rudder, affords protect-ion to the propeller and will prevent the tow lines from other boats from catching thereon, and will also serve to protect the propeller from floating obstacles. This arrangement also gives the rudder a suflicient hold upon the water, for all the purposes of steering the boat.
F, represents the propeller shaft. It works in a stuiiing boX (g) through the stern, and in a hollow shaft (H) within the boat. It has a projecting nib (i in Fig. II) which slides in a groove made in the hollow shaft as shown in Fig. II. This rib prevents the shaft from turning in the hollow shaft and at the same time allows of a longitudinal movement therein. II, hollow shaft. This has its appropriate bearings in the supports J J. The crank wheel (K) is attached to this hollow shaft, and power is applied thereto in the usual manner. This of course will drive the propeller shaft in any part of its longitudinal movement.
L, is a lever, with a fulcrum at a and an appropriate clutch on the propeller shaft at t, by which the steersman can give the pro peller shaft any required longitudinal movement, without disturbing its revolving motion. This lever may be made in a manner common for like purposes.
M, is a prolongation of the keel, or a projection therefrom, for the purpose of connecting and hinging the rudder bar (o) thereto. N, propeller. A propeller of any desirable form may be used in this arrangement. O, tiller; P, stern; R, keel; S, deck.
My improvement allows me to apply steam power to the propulsion of canal boats in a simple and economical manner, without materially lessening the tonnage capacity of the boat, and to give the propeller a position and protection in a full body of water when the boat is under way.
Another object is its adaptation to boats already constructed.
My improvement allows me to use boats of as large tonnage capacity as can pass the locks and enables me to propel t-he boat by one propeller, and to place it in a position, Where the Water has at all t-irnes unrudder, having a notch or recess therein to obstructed access to the propeller from all receive the propeller for the purposes and directions. substantially as herein set forth.
