To ttt whom, it may concern/.-
Be it known that I, ERNEST OHRrsTorHnR ROBINSON, a subject of the King of Great Britain and Ireland, residing at West Hartlepool, in the county oi' Durham, England, have invented Improvements in Vessels Propelled by Steam or other Motive Power, of which the following is a specification.
This invention relates to improvements in navigable vessels of the kind adapted to be propelled ahead or astern and provided with propellers actuated by steam or other motive power and located in a tunnel that extends from end to end of the lower part of the vessel.
, In order to effectively protect the propel- 1ers and at the same time to allow the Water free communication with the tunnel throughout its length, the bottom of the tunneiis formed of suitably-supported metal plates, and there are provided openings throughout the entire length of such bottom. The bottom of the tunnel may be closed with ships skin plating arranged so as to provide suitable openings at intervals throughout the length of the bottom and strengthened by stout angle or T irons extending from end to end of the tunnel.
v To provide suitable accommodation :for the motors without materially impeding the flow oi water through the tunnel, a portion of the ships bottom forming the roof of the tun nel is at a lower level than the other portions ofthe tunnel-roof and is adapted to form the iloor of the engine-room or a portion thereof, the end portions connecting the tunnel-roof portion of lower level to the tunnel-roof portions oi higher level being each inclined upwardly toward the respective end of the vessel, the propeller-shaft extending through appropriatelypacked glands in said inclined walls.
The vessel is provided with a rudder at each end, and in order to shield the rudders and provide cut-water ends for the vessel the stem-post or frame at each end of the vessel extends to the bottom of the propeller-shaft tunnel and adjacent to the corresponding mouth of the tunnel has formed in it a suitable opening in which the rudder is adapted to work.
Figures l and 2 of the accompanying illustrative drawings together show, partly in central longitudinal vertical section and partly in side elevation, one construction oi vessel according to this invention. Fig. 3
shows the vessel partly in end elevation and partly in transverse section.
The vessel illustrated is intended to be propelled ahead and astern, developing the same speed either way.
The propeller-shaft a is located in a longitudinally-arranged tunnel b, that is formed midway in the bottom oi the vessel. The ships bottom c, which (as usual) is double, is arched or bridged to `form the roof of the tunnel b, Fig. 3, and each stem-post or frame d extends below the bottom c to the bottom of the tunnel b, so forming ne cut-water ends for the vessel.
At a suitable distance from each end oi the vessel the corresponding stem-post or frame d is formed with an opening e, in which works a rudder f, the spindle or tailpiece of which passes up the corresponding rudder-tube g through the body oi vessel to the rudder-head on deck, from which it is worked in the ordinary way. Instead of the rudders extending outwardly toward the ends of the vessel, as is usual, they extend inwardly toward the middle oi the vessel. Rudders so arranged are more efficient in their action than rudders arranged to extend outwardly at the extreme ends o'l` the vessel. The ends of the propeller-shaft tunnel b terminate at the inner ends of the openings e.
The bottom of the tunnel b is built in with the ships skin-plating h, transversely arranged openings i being provided at intervals along the entire length of the tunnel-bottom, thus leaving the tunnel in free communication with the water. This plate-bottom` 7L is strengthened by two stout angle-irons or T- irons y', lying fore and ait and riveted to the plates.
The immersed propeller-shaft b works i'n a 9 number of suitable bearings lc, bolted tothe 5 top c of the tunnel. The propellers l are preferably put on in halves and secured by stout tapsbolts, the number of propellers used varying according tothe speed required.
To accommodate the engines m and boilers n, a portion o of the roof of the tunnel adapted to lorm the iloor ofthe engine-room is at a lower level than that of the remainder, and the end portions p, connecting the roof portion 0 of lower level to the roof portions of higher level are inclined upwardly toward the corresponding end of the vessel, the propeller-shaft I) extending through suitable packed glands r in the inclined walls p.
IOO
IIO
Instead of one propeller-shaft two or more may sometimes be provided, the proportions of the tunnel b being suitably modified.
It will be seen that in a vessel constructed according to this invention all the propellers are always immersed. They are also shielded from ice and other injurious objects.
