Application filed May 1 1911. Serial No. 628,164.
To all whom it may concern:
Be it known that I, WI LIAM J. A. LON- DON, a citizen of Great Britain, residing at Hartford,county of Hartford, State of Connecticut, U. S. .A., have invented certain new and useful Improvements in Elastic-Fluid Turbines, of which the following is a full, clear, and exact description.
My invention relatesto. elastic .fluid turbines and has for its main object. the provision of mechanism for safeguarding the turbine against in ury by the automatic sounding of awarning signal in the event of an abnormal pressure within the turbine casing.
In the accompanying drawings, Figure 1 is a side elevation, diagrammatic in character, on a reduced scale of part of a turbine equipped with my improved safety apparatusz F igu-EZ. is a relatively enlarged View, partly in section, of a modification. Fi 3 is a similar viewof another modification. Fig. 4 is a view on a'still larger scale/of another modificati0n. p
1 represents the external casing of a turbine; 2 represents. the main exhaust pipe; 3 represents a controlling valve in the exhaust tube; 4. represents a relief pipe made up as desired and lea ding from the interior of the casing 1 to the free side of the exhaust.
.5represents the casing of, 'what I will term, a pressure-controlled-check-valve, relati-vely enlarged views of the valvepro er being shown in Figs. 2, 3 and 4. The va ve in these figures is in all instances substantially the same and is. indicated by the numeral 6. 7 is a spring rovided to hold said valve closed or seated against the outflow of fluid excepting as at such times as the pressure back of the valve 3' in the region of the relief pipe 4 may rise to' a point beyond that adapted to be resisted by the means for holding the valve 6 closed, when, at such period, said valve opens, thereby relieving the pressure within the casing l. 8 (Fig. 1) conventionally represents a signaling device, in this. instance av Whistle, the same being in communication with the relief pipe 1 and preferably at a point between the valve 5 likewise operate only when'the pressure to open the and'the casing 1. This whistle may.
rises toa point corresponding substantially to the pressure at which the valved opens, so that simultaneously with the opening of said valve, or, if desired, slightlyin advance thereof, said whistle purpose of causing an alarm towarn the atwill lac-blown for the tenda-nt that thepredetermined pressure has been reached. Q
In Fig. 4, 8 represents a'whistle which is controlled directly by the movement of the valve 6. In this instance the valve 6'has a stem 9 which is mounted in a relatively long guide 10, and said stem is cut away as at l1.
12 is a duct which penetrates the valve stem guide 10 at apoint preferably sl-i htl above the reduced part 11 of the. valve iant when the valve is seated. 14 is a duct which penetrates said valve stem guide 10 preferably at a point adjacent to the reduced portion' 11 of the valvestem when said valve is seated. The valve stem accordingly operates as a valve in the whistle circuit. The
' duct 14 may lead, asdoes the reliefv pipe ,4,
to the casing 1', or indeed, toa source of compressed air. From theforegoingit follows that when pressure within the casing 1 rises to a point s'ufiicient to open the valve. 6, said operation will take place and simultaneously the valve stem will be moved to a position whistle circuitwhereby, and at which time, the whistle warning will. be sounded.
In Fig. 2; I'have shown a'modification in which 8 represents the Whistle, the same beirg directly connected by a pipe 15 with the exhaust 2*, preferably back of the valve therein. 16 represents a valve in thewhistle pipe 15. 17 represents a spring-controlledlever connected by a link 18 and arm 19 with the valve 16. When the lever 17 is in the position shown in F ig. 2, the whistle pipe 15 is closed. The lever" 17 is held in this position against the tension of'the spring 20 by the trigger 21. .In this instance, the valve stem 10" co -acts with the trigger 21 in such a manner asto trip the'trigger and release the lever 17 Whenever the valve 6 opens.
Upon releasing the lever l'Z, the spring .20
moves the stem in a direction to. open the valve 16, whereby the whistle warning will l ounded. 1
In Fig. 3 I have shown an equivalent arrangement of that shown inFig. 2, in which, instead of providing a whistle "Warning, I have provided an alarm bell 23, the same being operated in any suitable manner, for example, by an electric battery 25. 26-.27 are circuit wires. 28 is a lever moved in any suitable manner, as by a spring 29, which lever 28 operates as a circuit closer when released, that is, when it stands in the position indicated in dotted lines, Fig. 3. 30 is a trigger operated in the same manner as the trigger 21, illustrated in Fig. 2. When the trigger 30 is moved to releasethe lever 28, the spring moves the latter in a' directionto close the bell circuit, whereupon the bell 24: will sound the warning and the attendant is called to attend to the apparatus.
It will be seen by the foregoing that the above means will provide for the safeguarding of the operation of an engine of the type referred to by insuring against danger of accident or explosion due to pressure being built up higher than the predetermined pressure. Obviously, the exhaust past the alarm valve 6 may lead into the main exhaust or to a condenser, or indeed, into the open, it being immaterial-so long as a proper outlet is aflord d. Obviously, the warning may be sounded by a whistle or hell, as shown, or by any other suitable alarm device capable of operating with certainty and efficiency described.
in connection with the apparatus that there are many details It is obvious of a turbine engine construction which are well understood that I have deemed it'unnecessary to illustrate or describeherein, since I appreciate that any of the wellknown apparatus of the prior art may be associated with the apparatus diagrammatically shown herein without the exercise of invention, and indeed, without requiring disclosure herein.
