I To all whom it may concern:
' Be it known 'thatI, HAROLD EDGAR YAR- ROW, a subject of the King of Great Britain, residing at Scotstoiin, Glasgow, Scotland, have invented certain new and useful ImprovementsRelating to Emptying and Fillmg the Ballast-Tanks of Submarine Vessels,
ofwhich the followingis a specification.
: This invention relates to arrangements for filling and emptying the ballast tanks of submarinevesselso V i i Each ballast tank is usually provided with three valves, viz. a sea valve through which the water enters or leaves a tank, a venting valve to let the air escape when the water is "entering a tank,and a valve through which *compressed air enters to expel the water from a tanls As there are several ballast tanks in a sub marine vessel a large number of valves widely distributed must be operated in a short time when the, displacement of the vessel has to be rapidly altered. According facilitated by the provision of one or more central stations at which there are'levers or the like, each of which is adapted to control the setting of the valves of one tank or of a group of ballast tanks. n the accompanying drawing, Figure 1 is a part plan of a submarine vessel showing wdiagrammatically the position of the various ballast tanks and their valves and means tanks.
heads shown on the lines in connection with .the lever C. T D is alever for operating'the according to the invention for operating the valves; Fig. 2 shows diagrammatically an example of means for. operating a group of valves by air or llquid under pressure.
Fig. 3 shows a side elevation o: a modification or development of the actuating mechanism.
Fig. 4 shows a diagrammatic plan of this mechanism, and i Fig.5 shows the setting ofthe cams.
Referring to Fig. 1 A and B are control levers for operating respectively the valves of the port and starboard external ballast tanks E, B, T. C is a lever for operating the valves of the forward and aft trimming These trimming tanks are situated respectively forwardand aftofthe arrow valves of the main ballast tanksM, B, T. A V are compressed air valves, SV sea valves and VV venting valves.
Referring to Flg. 2, Ass a lever which cylinders,
will be moved to the right is displaced to the extreme position in the other direction, the sea and compressed air valves of the tank or group would be opened, so that the water would be expelled from the tank or group of ballast tanks.
The lever A is connected by a link Z) to a crosshead 0 to which are attached piston rods 6Z1, (Z operating pistons 0 c, 0,, working in cylinders f f f F rom the n F pipes g g 9,, lead to the mechanism ror valves and venting valves of the ballast tanks controlled by the lever A;' from each pipe such as 9,, branch pipes 7L h,,etc., may lead to connections of other valves of the same group, the pipe 9 for example, with its branches controlling the sea valvesof a group. The sea valve 2' is controlled, in the example shown, by means of a piston j in a cylinder is. Compressed air is supplied to a cylinder m through a lead Z and is admitted either through the lead a, to the left of the piston y or through the lead a, to the right of the piston; in the former case the sea valve 71 is closed and in the latter case opened. The admission of air to the leads n de pends upon the position of the piston valve 0 in the cylinder m. In the central position of the valve the supply of compressed air to the cylinder is closed; when the piston valve is moved to the right, air is supplied to the lead a and when moved to the left to the lead m The piston valve 0 is controlled by a small piston 72 sliding in a cylinder the cylinders q and f, are in communication through the fluid contained in the pipe 9,, which may be either compressed air, glycerin, water or other fluid, any movement of the piston 6 being communicated to the piston 79. If the handle of the lever A is moved to the left, the pistons 6 and 77 and the sea valve 2' opened; a movement of the handle of the lever A to the right will cause the valve 2' to be shut. At the same time, the compressed air and venting valves of the same tank will be operated as required by the fluid 1n the leads g and g acting upon devlces similar operating the compressed air, seav the air pressure admitted through the lead Z.
to those described in connection with the sea valve 2'. Also through the branch leads 72.
72. all the sea valves of the same group of ballast tanks may be simultaneously actuated and similarly through branch leads from the pipes g 9 all the compressed air and venting valves of this group -may be The operation of the compressed air ventilating valves and sea :valves may also be controlled d rectly by means of an electro 'motor actuating the spindle olthe valve through worm or rack gearing, the movement of the electro motor bemg controlled by the lever A.
The arrangement may also be such that in the intermedlate posltions of the lever A show nin Fig. 2, other combinations ofthe valve settings may be effected.
For examle 1f the lever A is olaced in an intermedlateposition it could be arranged to open only the venting valves, a further movement of the lever A being requlredto open the sea valves. hen the venting valves only were opened, this would adapt the control for the casein which hand,'or power driven, pumps are used for emptying the ballast tanks.
In Fig. 3, the lever-YA has a central position a, and four other positions 60,, a a (4,. On the shaft A to which this lever is keyed there are fixed three cam" plates, 1', s, '25, as shown in Fig. 4. lVorking in thegrooves .of the cam plates are three crossheads u a and '04,, connected by piston rods (Z (Z and d, to pistons 0 c, and 6 These pistons work in cylinders f f and f whlch are connected, as explainedin connection with 2', respectively, with the compressed air ballast tanks.
valves, sea valves and'venting-valves of the Fig. 5 shows diagrammatically the relative positions of the three cam platesr, s a and t. Whenthe lever A is in the position a all'the valves are shut, the piston rods 65,, (Z, and (Z, being all pulled to the left.
When the lever A is in the position (4,, it
will beseen that the cam plate 13 will not have moved the plston rod (Z as the path of the cam groove is circular from a to a so that the compressed air valves remain shut; the cam plate 8 will, however, have moved the piston rod (Z and, consequently, will have actuated the sea valves; the cam plate at Wlll not have movedthe plston rod (Z and,
hence, the venting valves will remain shut,
50 that with the lever A in the position a only the sea valves will be open.
When the leverA is in the position a, the piston rod cl, will have been moved, as well as the piston" rod 652, but the piston rod (Z willnot have been moved; and in this positionboth the sea valves and the compressed air valves will be open, the venting valves remaining shut. Similarly, with the lever A in the position a the sea valves onlyhwill be open; while in the position at, the sea valves and the ventingvalvesfwill both be open, and the compressed air valves .will remain shut.
