SPECIFICATION forming part 01 Letters Patent No. 787,182, dated April 11, 1905.
Application filed January 30, 1905. Serial No. 243,359.
' 0 ([7/ lr/mlit if mil/y Poll/(cruc- Be it known that 1, JOHN HU'roiirXos, en-
gineer, a subjectot' the Kingot' Great Britain, residing at 210 .\loorgate Station Chambers, in the city of London, lh'igland, have invented certain new and useful iinprovementsin and relating to means and apparatus for the gen eration of motive power by floating bodies" such as ships, buoys, floating docks, and the like for purposes of propulsion and other u es, of which the following is a specification.
ln propelling ships it is customary to use steam or other engines driven by burning coal, petroleum. or other fuel. This means of obtaining or generating power is very costly owing to the great consumption of coal or petroleum, besides the expense involved in the employment ot' a large numberot' men required to attend to the stoking of coal and watch the working of the largeamountot' machinery required by these means of moving ships or other floating bodies through water.
By this invention 1 provide means in any shi p or floating body without coal or petroleum for generating power either for propelling such ships or for other use which this power may be applied to,such as loading, unloading, lighting, and other like operations by the action of the ship and apparatus in contact with the water, through which water such ship or floating body may be moved.
The apparatus as arranged for effecting propulsion ot' a ship by means of a speciallydesigned turbine-driven screw is illustrated in the three accompanying drawings, ligured, respectively. 1 2, 3, and t.
Figure l is a cross-section amidships,wherein is shown a sectional view of a containingships body within the ligure 1/ I! 1/, the airbuoys i, with their attached water-tan ks c e, the air or water compressors e, the air or water conducting pipesf'f, the receiver the turbine /i, the semispherical friction-roller eases I, the safety-valve j, the bilge-keel links A, the movable bilge-keel the ships training 7/! and in, the deck-beams l 2, the navigatingbridge 3, the starting, stopping, and reversing valve gear and connection-le- VPI'S 11 H N.
Fig. 2 is a side elevation and section comtion of the containing-ships body.
bined in one drawing, showing a longitudinal sheer-draft and part-sectional view of a porln this ligure the shell-plating is shown as having been removed, the more plainly to admit of the interior of the air-buoys 7/ 7; being seen, together with their subtended and attached water tanks or compartments (1 c, the air-compressors or water-pumps If 1 the ships bodyt'raining HI and m, the rib-t'ranie stations; -t, the balancing-tank water-intake holes 1/ at the bottom of each water-compartinent, the piped or hollow piston-rod p, the steel guiderods (1, upon which the air-buoy l; and water tank t run and work, a sectional view showing the braces, struts, and internal constructional features of the air-buoy and watertank 0, the bilge-keel links Z', and the inovable bilge-keel Fig. 3 is a plan view taken amidships, showing the general arrangement of the diflerent parts, including the air-buoys 7/, the waterpumps or aircoinpressors I, the conductingpipes f, the receiver r the turbine it, the satety-valvej, the side body-framing m and iii, and the frame-station deck-beams in.
At convenient points along the ships side between the outer frames and shell-plating ill in and the inner shell and plating m m of the ships body the power-buoys I; l), with their attached water-tank I v, are hung permanently onto the piston-rod p, which, as will be seen by the drawings, is provided with a passage through its center extending from the point at S to T for the purpose of letting air out of the water-tanks c w to enable their being lilled with water or regulated so that they occupy their proper position on the load water-line. \Vhen a ship litted with these buoys and tanks is launched or lowered into the watcr,the tanks 0 c are full of air, by the buoyancy of which the tops of the power-buoys at I r are forced upward in the direction of p p, but they are lilled and adjusted with the proper quantity of water to bring the division-plates a x to a level with the load water-line when the ship is at a standstill, which is etl'ected in the following manner: Caps titted with valves are screwed onto the top ends of the. piston-rod at p p. These valves are designed to be opened by means of the turning of these caps, thereby allowing the air in the water-tanks 0 0 to escape at p'p, Fig. 1, and admitting water into the tanks through the holes 0 in their bottoms in the direction indicated by the arrows 1 1, Figs. 1 and 2, and on the admission of the water the combined tank and air-buoy c and L begin to descend into the water at t t. The valves at p p are closed as soon as the dividing-plate s has reached a point level with the load water-line, which is ascertained by a pointed indicator n, fixed to and moving with the piston-rod 1), Fig. 1, in conjunction with a graduated scale 1;, fixed to the top of the compressors c a, Fig. 1. \Vhen the position of the combined power-generating tanks 0 0 and buoys L b have been thus adjusted, they are then allowed to float on the water-line, being in free communication with the water outside the ship and subject to every movement of waves both in the water and any movements produced by the water waves on the ships containing them. The upward movements of the piston-rings w in, Fi 1, are caused (when the containing-ship moves dow nward) by the buoyancy of the air contained in the buoys 5 7), Figs. 1, 2, and 3. Thedownward movements of the piston-rings w w are caused (when the containing-ship moves upward) by the combined weight of the iron or other materials forming the piston-rod p, the combined buoy and water-tank added to the weight of the water in the tanks 0. These weights (when the dividing-plate s is at the water-dine) combined are equal to the buoyancy of the air contained in the buoys 5, thereby producing a uniform pressure in the compression-cylinders e a, Figs. 1, 2, and 3, during both the up and down movement of the piston-rings w w.
The air-buoys 5 b and water-tanks c 0 have fixed at both their longitudinal ends two semicircular grooved friction-rollers, (shown at a 00,, Figs. 1, 2, 3, and 4.) These frictionrollers are h'xed into semispherically-bossed recesses or cases i i in the ends of the buoys b and tanks 0, Figs. 2, 3, and also shown in side view, Fig. i. These friction-rollers are made to fit by their curved periphery and to work or run up ordown on or against vertical steel semicircular guide-rods (shown at q q, Figs. 2 and 3 and also on side view below Fig. 1) which are fixed to the ships framing. Thus it will be seen that by this means the tanks 0 0 and the buoys Z) 6 have freedom to move up and down, running on their rollers in this guiding-path in any way they may be influenced so to do by the water surrounding the water-tanks at t 6, Figs. 1 and 2, or by the movements of the containing-ships. Onto the bottom of the water-tanks 0, Figs. 1 and 2, is fixed and hinged suitable links at k k, which are also attached, by means of hinges, to the movable bilge-keels at Z. These bilgekeels are fixed in sections at convenient points between the rib-frame stations of the exterior shell-framing of the ships body. Any pressure against the top surface of these bilge- .keels caused when the ship rolls or pitches during the upward movement is transmitted through the tanks 0 0, buoys .7) 7), and pistonrod 3) to the piston-ring an, thus tending to increase the pressure in the air being compressed or water pumped and forced during the downstroke through the compressors e Similarly, any pressure against the bottom surface of these bilge-keels Z, caused when the ship rolls or pitches during the downward movement, is transmitted through the watertanks 0 c, buoys 7) b, and piston-rod p to the piston-ring 00, thus tending to increase the pressure on the air being compressed or water pumped and forced during the upstroke through the compressors e e. The ends of each of these bilge-keel sections are tapered down to thin pliable spring-steel tins for the purpose of assisting propulsion of the ship to which-they may be fitted. As the air is being compressed in the compressors e c it is forced down through the pipes f f, Figs 1 and 3. leading in the direction of the arrows 5 5, Fig. 1, sectional view, and passing thence into the receiver 9, Figs. 1 and 3. From the compressor a the air passes (when desired by the navigating officer on the officers bridge) into the turbine or other motor 71., Figs. 1 and 3, whereby the ship is propelled according to the direction given by the valves. Air-holes 7 afford vent from and access to chamber \Vhen water is pumped and forced for motive power by this invention the working movements are the same as above described; but in this case the turbine or other motor is placed in a position well above the water-line of the ship to enable the water after being used to return whence it came.
It will be seen by the drawings that by means of the lever-handle 6, Fig. 1, and the connecting-rods and angle-levers n 92. a w. a, which control the valves communicating between the receiver g and turbine /t, Fig. 1, or other motor any oflicer on the oflicers bridge of a ship may at will manipulate or control the working of the screw or other propeller.
The lever-handle 6 may be connected with a semicircular disk, upon which there is a graduated scale indicating the position of the lever to produce at the screw-propeller the motion required to go ahead, stop, slow down, back, slow back, or any speed both forward and backward required within the range of the power thus generated, or the indication may be otherwise effected. Although in the application shown the invention is limited to the propulsion of ships the power may in addition or alternately be applied to other uses such as pumping, raising, and lowering, generation of electric energy, or other uses.
