PROPELLING MECHANISM FOR VESSELS.
SPECIFICATION formingpart of Letters Patent No. 742,522, dated October 27, 1903.
Application filed March 16, 1903.
To ctZZ whom it may concern:
Be it known that I, TELEMAQUE THOMAS TI- MAYENIS, a citizen of the United States, residing in Boston, in the count-y of Sufiolk and State of Massachusetts, have invented an Improvement in Propelling Mechanism for Vessels, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to a propelling mechanism for steamships, yachts, launches, and like vessels which employ steam, electricity, or other motive power.
The invention has for its object to provide a propelling mechanism with which the speed of the vessel can be increased without increasing the power employed to drive the vessel and which can be applied to vessels of the character referred to at a minimum expense.
In accordance with this invention I employ an annular propeller comprising a suitable annular frame having attached thereto a plurality of blades or vanes which are set at an angle to the axis of the annular frame and secure said frame to a sleeve which is fitted upon and secured to the shaft of the ordinary screwpropeller. The sleeve referred to is keyed or otherwise secured to the screw-propeller shaft, so that the screw-propeller lies within the annular frame referred to. The blades or vanes are made of such size as to leave a space between them and the outer ends of the screw-propeller. These and other features of this invention will be pointed out in the claims at the end of this specification.
Figure 1 represents in section and elevation a vessel provided with a propelling mechanism embodying this invention; and Fig. 2, a rear elevation, on an enlarged scale, of the propelling mechanism and a portion of the vessel.
The vessel a, provided with the screw-propeller 1), fast on the shaft 0, may be of any suitable or usual construction. In accordance with this invention the screw-propeller b has cooperating with it an auxiliary propeller, which is secured to the shaft-c, so as to rotate therewith. The auxiliary propeller conblades or vanes 11, secured to an annular frame or support, which may be Serial No- 147887. Qlo model.
made as herein shown, and consists of two rings e f, between which the blades or vanes d are located and secured against movement by nuts g on the shafts or center rods h of said blades or in any other suitable manner. The blades (1 are set inclined to the shaft 0 and project within and without the annular frame or rings (if. The annular frame is secured by rods or arms t or in any other suitable manner to a sleeve j, so as to leave the center of the annular frameclear to enable the vanesor blades d to be brought into line with the propeller b. The sleeve is fitted over the shaft 0 and is keyed or otherwise rendered fast thereon, so as to turn therewith. The' sleevej is secured to the shaft so that the auxiliary blades 61 are in line with the main propeller b, as represented in Fig. 1, and the blades 01 are separated from the outer ends of the blades of the propeller b. by a space, which affords opportunity for the passage of the water between the outer ends of the blades of the main propeller and the inner ends of the blades d.
The sleeve j may be held from longitudinal movement on the shaft 0 by collars m 'n, socured on said shaft at opposite ends of the said sleeve, or in any other suitable manner.
It will thus be seen that the auxiliary propeller can be readily applied to the propellershaft 0 of steamships, yachts, launches, 850., now in use at a minimum expense, it only being necessary to remove the screw-propeller b from the said shaft, apply the sleeve thereon, secure said sleeve to said shaft, and replace the screw-propeller. It will further be seen that increased propelling action is obtained by both propellers working in unison. By securing the auxiliary propeller to asleeve which is fastened to the shaft 0 the auxiliary propeller does not in any way interfere with the main propeller and can be so strengthened and secured to the sleeve j as to avoid liability of breaking while in action.
I claim- 1. In a vessel of the character described, in combination, a shaft provided with a screwpropeller, an auxiliary propeller comprising an annular frame, a plurality of blades or vanes secured to said annular frame, a sleeve fast on the said shaft, and means to secure said annular frame to said sleeve, substantially as described.
2. In a vessel of the character described, in combination, a shaft provided With a screwpropeller, an annular frame, a plurality of blades or vanes secured to said annular frame substantially in line with said screw-propeller and separated therefrom, a sleeve fast on the said shaft, and means to secure said annular frame to said sleeve, substantially as described.
3. In avesscl of the character described, in combination, a shaft provided with a screwpropeller, an auxiliary propeller comprising rings, vanes or blades interposed between said rings and secured thereto at an angle to said shaft, said vanes or blades projecting within and Without said rings, means to render said blades or vanes fixed or immovable, a sleeve fast on said shaft, and rigid arms se- TELEMA QUE THOMAS 'IIMAY EMS.
