ENGLAND.
SHIP-PROPULSIGN INSTALLATIGN.
Original application filed January 19, 1918, Serial No. 212,746.
To all whom it may concern:
Be it known that I, DAVID CHRISTOPHER BLACK, a subject of the King of Great Britain and Ireland, and residing at 88 Park road, Newcastlc-upomiyne, in the county of llorthuinberland, England, have invented certain new and useful Improvements in and Relating to ShipPropulsion Installations, of which the following is a specification.
The present invention relates to ship pro- A rdsicn installations of the type where two or more motors or sets of motors drive through gearing, two or more propeller shafts, and particularly of the type described in United States application No. 21274:?) of which this case is a division.
The object of the invention is to arrange the engines, intermediate shafts and gearing in such a manner as to give the maximum hold space in the vessel and to minimize the hold space occupied by the power transmission system.
The invention consists in a marine propulsion installation in which a plurality of propeller shafts are employed connected with driving means by intermediate shafts which are geared both to the propeller shafts and to the driving means, the intermediate shafts being displaced axially out of line with the propeller shafts and nearer the sides of the ship than the propeller shafts so that a greater hold space is provided.
- eferring to the accompanying drawis plan of a two-shaft installaged acccrding to the invention.
r s a plan of an installation in which ado itio al propeller shafts are provided, while Fi 3 is a plan of another modification in wnich additional propeller shafts are employed.
In the form of the invention shown in Fig. l, the intermediate shafts l, 2, are placed in tunnels 3, a, built against the sides of the ship. The reduction gearings are divided, the first reductions 5, 6, being placed in the engine room in such a. position that the intermediate shafting is well outside the main portion of the engines and gearing. The second reductions 7, 8, are placed as far aft in the vessel as possible and are so arranged that the propeller shafting a b is considerably nearer the central line of the vessel than the intermediate shafting. In this manner a very considerable width of Specification of Letters Patent.
hold space is provided without any central tunnels for the shafting. The gears may be single or multiple.
In the form of the invention shown in F 2, in addition to the propeller shafting a, b, and intermediate shafts 1, 2, additional propeller shafts 0 (Z and intermediate shafts 11, 12, are provided, the intermediate shafts being geared at one end of a propeller shaft and at the other end to the engines.
the form of the invention shown in Divided and this application filed November Serial No. 339,664.
Fig. 3, the additional propeller shafts 0,
(Z are passed along tunnels near the sides of the ship and are geared to the engines by gearing 15, 16.
Having now described my invention, what I claim as new and desire to secure by Let ters Patent is 1. In marine propeller installations a plurality of propeller shafts, driving means in an engine room, shafts intermediate the driving means and the propeller shafts and extending along the hull of the vessel aft of the engine room, each of sad intermediate shafts being disposed axially out of line with the propeller shaft it is to drive, tunnel means in which said shafts are located and gearing between each aft end of the intermediate shaft and its propeller shaft, said gearing being spaced from the engine room aft the hold, said intermediate shafts being displaced toward the side of the ship from the propeller shafts, providing greater un broken hold space.
marine propeller installations a pinrality of propeller shafts, driving means in an engine room, shafts intermediate the driving means and the propeller shafts and efitelltilng' along the hull of the vessel aft of the engine room, each of said intermediate shafts being disposed axially out of line "it-h the propeller shaft it is to drive, tunnel means in which said shafts are located and gearing between each aft end of the intermediate shaft and its propeller shaft, said gearing being spaced from the engine room aft tie hold, said intermediate shafts being displaced tcward the side of the ship from the propeller shafts, providing greater unbroken hold space, said tunnels being placed along the sides of the vessel, as set forth.
In testimony whereof I have signed my name to this specification.
DAVID CHRISTOPHER BLACK.
