` when in danger of collision or in other emergencies, the same being under the immediate and instant control of the helmsman or other officer of the vessel, whereby steam may be instantly cut off from the engine and directed into the water at the bow of the vessel and in the direction of movement of the vessel, at the same time avoiding complication of machinery and obtaining a de- .vice which is always ready for instant use and which may be installed economically.
lV 1th the above and other objects 1u View,
i the nature of which will more :fully appear as the description proceeds, the invention consists in the novel construction, combination and arral'lgement of parts as herein fully described, illustrated and claimed.
ln the zufcompanyiug drawings:-Figure 1 is a vertical longitudinal section through a sufficient portion of a vessel to illustrate the application of the present. invention thereto. Fig. 2- is a vertical transverse section through the same.
Referring to the drawings, 1 designates t-he hull of the vessel, 2 the deck thereof, 3 the bridge, 4 the boiler room, 5 the enUine room, (3 the engine and 7 thc engine shaft.
In carrying out the present invention, an engine cut off valve casing 8 is interposed. in the main steam pipe 9 leading from the boiler 4 to the engine G. This valve casing embodies a valve seat 10 in conjunction with which, a cut offl valve 1.1 cooperates. The valve 11 is normally open as shown in Fig'. 1, being held open by the steam pressure in the pipe 9 and said valve is provided with a stem 12 passing through a stuffing box 13 having secured to the other end thereof a piston 15. A steam pipe 16 leads from the main steam pipe 9 upward to the bridge 3 and the return portion 16 of said pipe communicates by means of a tee with a double branch pipe 18, 18', one branch of which leads into the head of the valve casing 8 so as to allow the steam to act upon the piston which is of materially larger` area than the valve 11 so that when steam is admitted to act against the piston 15, the effect is to lclose the valve 11 and cut off the supply of steam to the engine 6 thereby stopping the propeller of the vessel. The other branch 1S of the steam pipe leads into the head of another valve casing 19 in which is arranged a brake valve 20 controlling communication between the main steam pipe 9 and a large exhaust pipe 21 as clearly shown in Fig. 1. The valve 20 is provided with a stem 22 to which is secured a piston 23 operating in a cylinder 24 forming an extension of the valve casing 19. The piston 23 is of considerable larger area than the valve 20 so that when steam is admitted to act against the piston 23 the effect will be to open the valve 2O and allow the steam to pass from the main pipe 9 into the exhaust pipe Q1.
The exhaust pipe 21 is connected by a teecoupling to a horizontal pipe Q5 near the bow of the vessel, the opposite ends of the pipe 25 being provided with forwardly facing flaring nozzles 2G which are arranged outside of the hull so as to direct the exhaust steam forward or in the direction of movement of the vessel for the purpose of arresting the forward movement of the vessel. The pipe 21 is provided with a valve casing 27 in which is arranged a check valve which is normally closed by the water pressure passing inward through the nozzles 26 and which opens under the action of the exhaust steam to allow the steam to escape through the nozzles 2G. The pipe 1G is provided with a stop cock 2S adapted to be oper ated by the helmsman standing on the bridge 3 while a similar' stop cock 29 controls the branch 1S of said steam pipe and is arranged in the engine room so as to be in ready reach of the engineer.
The operation of the mechanism hereinabove described is as follows z-In case of collision or other emergency when it is desirable to stop the vessel, the helmsman standing on the bridge opens the stop valve 28 whereupon the steam pressure passing through the pipes 1G and 1G and through the branches 18 and 1S acts on the pistons 20 and 23 to close the valve 11 and open the valve 20. This cuts off steam from the engine and transfers said steam into the ex- Patented Mar. 29, 1910.
`ulates the reverse gear of the engine and then opens the stop cock 29 which again admits the steam from the pipe 9 to the engine 6, thus causing the propeller to rotate in a reverse direction which materially assists in stopping the forward progress of the vessel.
The whistle 30 also acts as a vent for the steam in the pipes fed by the main steam pipe 9 and by relieving the pressure on the pistons 5() and 23, the valves are allowed to bereturned by the steam pressure in the pipe 9 and their normal positions shown in Fig. l.
I claim f l. In a device of the class described, the combination with the steam pipe which supplies the engine, of an exhaust pipe arranged to discharge the steam from the bow of a vessel in a forward direction under water, and means for shutting off steam from the engine and admitting it to said exhaust pipe comprising valves in the steam pipe, and steam actuated pistons on the stems of said valves.
2. In a device of the class described, the
combination with the steam pipe which supplies the engine, of an exhaust pipe arranged to discharge the steam from the bow of a vessel in a forward direction under water, and means for shutting oft the steam from the engine and admitting it to said exhaust pipe comprising a valve between the boiler and engine, another valve between the boiler and exhaust pipe, and steam operable pistons on the stems of said valves.
3. In a device of the class described, the combination with the boiler and engine and the main steam pipe leading from the boiler to the engine, of an exhaust pipe arranged to discharge steam from the bow of the vessel in a forward direction under water, a valve controlling communication between the main steam pipe and exhaust pipe, another valve arranged in the steam pipe between the boiler and engine, pistons for actuating said valves, a valve operating steam pipe leading from the main steam pipe to the chambers in which said pistons are mounted, a stop cock controlling said valve steam pipe and arranged adjacent to the bridge of the .vessel, and another stop cock controlling said pipe and arranged in the engine room.
In testimony whereof I aiiix my signature in presence of two witnesses.
