To (zZ/Z 107mm t may concern.'
Be it known that l, CHARLES Marius Morris, a French citizen, residing at Paris, in the French Republic, have invented new and useful improvements in Propellers for Vessels, of which the following is a specification.
This invention is an improvement in ships propellers of the continuously revolving turbine type with turnable easing, and it consists in the construction and combination ot means forming a pair of' co-acting suspended circular and symmetrically disposed turbine casings each with top and bottom inlet ports and a single lateral eduction port; power-means 'for simultaneously and uniformly driving the turbine wheels; and controlling means ior turning the turbine casings symmetrically in opposite directions to one another to thereby utilize the education currents for driving and stopping the ship.
According to my invention l' provide a pair of suitably divided surrounding turbine casings each having internal flanges to form a circular channel, opening into the aforesaid eduction port, in which a plurality of radial blades or vanes are caused to circulate by the rotation of a suitably driven turbine shaft. I also provide readily operated reliable gear for setting, changing or adjusting the direction of the eduction port.
It is my object to provide a self-contained mechanism adapted to replace the usual screw-propeller and which, by continuous uniform rotation and without additional or extraneous parts, will serve for driving ahead and astern, slowing down and stopping a ship or boat.
This object I attain by the means illustrated in the annexed drawings as being the preferred embodiment of my invention.
In these drawings, Figure l is a vertical central section of one of the suspended turbines, the operating mechanism being omitted for the sake oi clearness.
Fig. 2 shows in elevation the arrangement of combined turbines for propelling vessels; Figs. 8, i and 5 are plan views showing the important positions for the forward, and
rearward movement of the vessel and for stopping same by the turning of the eduction port.
Referring to F ig. l., a Shows radial blades driven by a central shaft c so as to circulate in a circular channel formed by inwardly projecting flanges 5X provided in a suitably divided casing L. rl`he casing b has inlet openings 1 and Z22 at top and bottom while a single lateral eduction port d is provided in the otherwise closed turbine casing. The casing Z; is rigidly attached at the stern of the ship to a tubular suspension body e which provides internal bearings for the shaft c, The body e is suitably carried in a socket rigidly fixed to the vessel to be driven by the turbine. The shaft c is constantly driven at proper speed by mechanism, such as mitre wheels or the like fast on shafting connected with a motor.
As shown in Fig. 2 I arrange two turbines to work together, their driving mechanism being 'enclosed in protecting casings f1. Independent of the inner revolution of the turbine vanes u, it is necessary to provide gear for turning the turbine casing in order to set the eduction port d at the various angular positions required for controlling the vessel, in going ahead or astern, slowing down or stopping. For the relative angular displacement of the eduction port of both turbines arranged as in Fig. 2, I may provide co-acting chain drives g operating chain wheels 7i fast on the upwardly protruding body e connected with the turbine casing t, said chain drives being operated by chain pinions h2 through the intervention of gear wheels its, 7L. The shaft of one of these gear wheels say, that of 71,3, is journalled in a sleeve fast on the casing f1 and is controlled by a hand crank Thus, in turning said crank i the eduction ports oi both turbines turn in opposite directions through a corresponding angular space to each other. The arrangement oiE the divided enclosing casing with internally flanged circular channels for the turbine blades gives great eiiiciency to the turbine, insures ready and plentiful access for the inflow to the central part of the turbine casing and a strong eduction current through the mzgularly disposed eduction port so that J. Vessel fitted with e pair of such turbines can be driven fast or slow and stopped easily and securely by the foi-oe and direetion of the eduotion currents.
I elaimz- Self-contained mechanism for driving and stopping Ships through the intervention of eduotion currents', which consists in two similar suspended educt-ioii devices, means for producing eduetion cum-ents, and means for symmetrically 'varying the direction of eduetion Within Circular and Oppositely turning paths.
