T0 @ZZ whom it may concern,.- y

Be it known that L RUPERT ScIIULTIIEIss, a citizen ofthe UnitedStates of America, and-a resident -of Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Start.- ing-.Valves for Compound Locomotives, of which the following is a specification. My invention relates to improvementsv in starting valves for compound locomotives adaptable to regulate induction and eduction of motive fluid, and has especial reference to a valve of this class adapted for embodiment with compound engines.

Among numerous objects attained by this invention is the production of a balanced rotary valve of simple kand inexpensive construction adaptable to either asingle or compound engine and readily adjustable at will to run a compound engine either simple,single, or normal;

The above-mentioned and other objects equally as desirable are attained bythe constructions, combinations, and arrangement of parts, as disclosed on the accompanying drawings, set forth in the following specification, and succinctly pointed out in the appended claims.

With reference to the drawings filed herewith and bearing like reference characters for' corresponding parts throughout, Figure 1 is a view of a portion'of the head end of a com` pound locomotive in front elevation and' shown with my improved valve embodied with `the motive cylinders thereof andone aside viewof the valve as preferably formed and indicates the seat thereof in longitudinall section online 3 of Fig. 4 and the valve set to .operate a compound engine normal.

4v is a .transverse section of the valve and its Seat on line 4 of Fig. 3 viewed as the arrows Iiyandgindicates the plug of' the valvesub- Fig.

l stantially midway its path of travel. Fig. l5-

is a similar section to Fig. 4, taken on line 5 of Fig. 3 looking as the arro'wsindicate and shows the intercepting-shell set to operate a compound engine normal and the valve-plug midway its path of travel. Fig. 6 is a like sectionon line 6` of Fig. 3 viewed as the arrows liy, and Fig. 7 indicates alike view of the valve in transverse section on line .7 ofV Fig. 3 looking as the arrows point. A n

This valve comprehendsa rotative cylindrical valve-plug, as 10,- arranged'to receive motive fluid interiorly and having suitable ports for admission and distribution and a thereby conveniently arranged to lie free for independent movement in said seat, which is conveniently'formed in communication with suitable fluid-passages leading to and from the engine-cylinders, as high and low lpressure cylinders, (marked a and b, respectively, inFig. .1 or o and CZ, respectively, in Fig. 2.) In the present embodiment valve-plug 10 is formed with both ends closed and with suitable partitions, as 9 and 9', Fig. 1, or 9, Fig. 2, arranged to .afford separated chambers in the val-ve,f;as'an induction-chamber 14, adapted to receive live Huid primarily for distribution to thecylinderof a single engine or the high-prese sure cylinder of a compound engine; an inter- 1 mediate chamber 15, Fig. 1, or 15, Fig. 2,'to

receive the exhaust from ahigh-pressure cyl- Y inder or live fluid primarilyfa'nd also inter.-

mixingly with said exhaust, if desired, for distribution therewith tothe low-pressure cylinder when the engine is operating compound or for distribution'of` said live fluid alone to the low-pressure cylinder when the engine is operating simple, and anexhaust-chamber 16,

IOO

Fig. 1, or 16, Fig. 2, adapted to receiveuid exhausting from both or either cylinder and to act secondary to either the induction-chamber 14 or intermediate chamber 15, or both, as determined by the nature of the engine, whether single or compound, or by setting the intercepting-shell to operate compound engines normal or simple.

From lthe foregoing it Will be understood that the passages for motive fluid leading to and from the cylinder or cylinders of an engine incorporating my valve are arranged in conjunction with a seat, as 13, and in conformity with the ports and apertures as arranged, respectively, in the plug and shell of the valve in accordance with the nature of the engine. In the present instance induction-chamber 14 is arranged in one end of plug 10, and a transversely-disposed port 19 is suitably placed in 4 the Wall of said chamber, Fig. 4, so as to lie constantly in communication with alive-fluid passage, as 2O, leading from a source of supply to seat 13, and oppositely-disposed ports 22 are formed in said wall, so as to alternately and intermittently register with respective fluid-induction passages 20', which lead-from said seat to opposite ends of an engine-cylinder, as a high-pressure cylinder a or c, Figs. 1 and 2. Exhaust-passages 23 are arranged to leadA the Huid exhausting from respective ends of said cylinder back to valve-seat 13, and the plug and shell of the valve are suitably formed to direct this iiuid to intermediate chamber 15, Fig. 1, or 15, Fig. 2, for distribution for further use in the engine, or to chamber 16, Fig. 1, or 16', Fig. 2, for exhaust, and thereby render it possible to operate the engine single.

In the preferred construction of the valveplug partition 9 is disposed transversely thereof adjacent one end `to form induction-chamber 14 at that extremity of the valve, and partition 9' is disposed longitudinally the plug between said transverse partition and the opposite end, so as to form intermediate and exhaust chambers, as 15 and 16, respectively, Figs. 1, 3, 5, and 7, and intercepting-shell 12 is rendered of suitable length to cover said plug over said

chambers

15 and 16. In the Wall of chamber 16 a suitable exhaust-port 35 is arranged, Fig. 7 and apertures, as 36,v are formed in the opposing Wall of shell 12 relatively thereto and in conformity With an exy periphery and adapted to bring said apertures into communication With exhaust-passages 23, leading from the high-pressurefcylinder,when the shell isadj usted to run the engine single or simple, and ports 28 are arranged inthe wall of pluglO at suitable points to alter-v Yand is arranged so as to register with one passage 23 When the shell is properly adjusted to cause one of the apertures 26 to lie directly in line with the opposite passage 23, as indicated in Fig. 7, and ports 24 are formed in the Wall of plug 1() at suitable points, so as to intermittently register with a

respective aperture

26 or 26 and admit the. fiuid exhausting through passages 23 to chamber 15 for distribution and further use in the engine.

In the present instance live steam is admitted direct from the source of supply to intermediate chamber 15 through an aperture, as 30 or 31, Fig. 5, formed in shell 12 at suitable points to register with a supplemental live-uid passage, as 29, When the shell lies in either of its adjusted positions. These apertures are controlled by plug 10, in the wall of which oppositely-disposed ports 28 are arranged to intermittently admit Huid to chamber 5 "rom respective passages 29 and 31 when either of said apertures register therewith, and thereby render it possible to distribute said luid to the low-pressure cylinder When the engine is running either simple or compound. The fluid admitted to intermediate chamber 15 is conducted to the low-pressure cylinder by passages, as 34, Fig. 6, a1'- ranged in communication with respective ends of said cylinder and with valve-seat 13, Fig. 6. Apertures, as 33, are formed in pairs at suitable points transversely the wall of shell 12, so as to register with these passages 34 when said shell lies in either of its adjusted positions, and ports 32 are formed at opposite points through the wall of plug 10 to intermittently release fluid through respective apertures 33, and thereby supply the low-pressure cylinder. From the foregoing it will be understood that when shell 12 is adjusted to run the engine simple the exhaust from the high-pressure cylinder passes into chamber 16 for final exhaust and only live Huid is admitted to intermediate chamber 15, which is then distributed to the low-pressure cylinder. Should, however, shell 12 be adjusted to run the engine normal, the exhaust from the highpressure cylinder passes into the intermediate chamber 15, and live fluid is also admitted thereto from supplemental passages 29 and intermixes with said exhaust and passes therewith to the low-pressure cylinder, as heretofore set forth. The low-pressure cylinder exhausts through passages 39, Fig. 5, into chamber 16, Whlch 1s constantly open to passage IOO IIO

27, as heretofore set forth.' Shell 12 is formed with apertures 38, arranged in rpairs in v'the wallatsuitable `points to'give said passages'I 39 a delivery-way through said shell at all times', and ports, as 37,v are 'conveniently'provided=in'the wall ofplug 10 at suitable oppo-I site points to intermittently registerwithrespective apertures 38 to give a free exhaust at proper times.

As now considered valve-plug 10 is operated by means'of a crank, as` 40, fixedto a'suitable stem of the plug and operably connected to any suitable reversing-gear, and theinterceptingv-shell 12 is adjustedthrough the me#- dium of a similar 'crank 41, attached to the stem thereof and operably connected to any suitable mechanism for turning the shell as desired to vary the application of motive fluid.y

I t will beunderstood that 'the several pas sages, apertures. and ports' are arranged in' relative positions in conformity with the length of adjustmentof. the shell vand travel of theplug and" that thelvalve ispractically balanced at all times owing to the passage ofthe motive fluid therethrough; furthermore, that the valve can be formed without the'referencey to the'I supplemental passage 29, and thereby made to operate an engine single, or it can be arranged to distribute Huid from said passage haustfrom cylinder a, Fig. 1, passes through passages 23,Fig. 7', to apertures 26, respec-V tively, and is admitted to'e'xhaust-chamber `16 through ports 28. When it is desired to run the engine normal, shell 12 is set to register aperture-26' with one passage' 23, Fig.7, and 1 thus cause the fluid'exhausting from said cylinder-"tol pass into intermediate chamber '15 through ports 24:,'and isdistributed to they low-pressure cylinder through ports 32, Fig. 6, apertures 33,v andpassages 34., and said cylinder exhausts to chamber 16 through pas-4 sages'39, Fig.' V5, apertures 38, and ports 37.. If thevalve is arranged to admit fluid fromy passage 29 when'shel-l 12'is Iadjusted to runa compound engine normal, the said fluid will enter 'intermediate chamber lthrough aperture 31 and ports 28', Fig. 5, and thence Apass to the low-pressure cylinder, as heretofore set forth. If thevalve is arranged to admit said fluid t'o the intermediate chamber only when the shell is adjusted to operate a compound" engine simple, the aperture 31 is omitted, andM the fluid will only be admitted through said communication withy passage 29.
