- o Surdykowski now by judicial change ofnamef o Charles J. ASurdy; assignorsqto The Standard l StokerY Company,

of Delaware Incorporated, a"corporationA This invention relates*generallyr to features `:of

Ylocomotive construction-and more particularly to the underside of-a locomotive deck andaccess thereto Vfor purposesof inspection or repair mayV be conveniently had from above:l the deck.

' It is a further object of this inventionto provide such an arrangement wherebyVV the stoker orjother locomotive accessory "driving A- motor` Vmay* be mounted to occupy suchspace onthevlocomotive which has not heretofore been utilized; Y I

With the above and other' `objects and advantages in view,` the invention consistsin the features of construction, the combination of velements and arrangement of parts herenaftermore Afully described and claimed, and' illustrated in the accompanying drawing, in whichl 1 Y Figure 1 is acentral verticallongitudinal section through a portionpof la locomotive with a Stoker and Stoker driving motor mounted thereon and shown inelevation, parts of which are broken away; Y.

[Figure 2 is an end elevation, partly-in section and partly broken away, of the structure shown in Figure 1; and 'Y Figure 3 is a sectional view 4taken on theV line 3 3 of Figure l.

In the drawing, thelocomotive is represented generally by the numeral A, and comprises the engine unit lli and the tender unit Illa, which are provided with a deck' II. The engine unit IU includes a boiler irebox I2, at the'rear of which is the usual war leg or backhead I3, the latter having a ring opening I4 therethrough.A

The locomotive is provided with a suitable form of Stoker, designated generally by the numeral I5, and which comprises a transfer conduit I6 leading from a suitable source of fuel supply, as from the tender Illa, forwardly beneath the locomotive cab deck II and above the frame I'I. A riser conduit I8 extends upwardly andforwardly from the discharge end of the transfer conduit I6 through the deck II to the lower portion of the ring opening I4. The upper portion of the ring opening I4 may be closed by a suitable liredoor arrangement I9. The locomotive unit of the stoker I is supported from the locomotive 52 and suitable-'securing,means boiler' baekheadl not neces- I Y sarily v from. the Vfoundation ring 5;!) v at .its lowerv end loy-A abraoket5l andnfrom the rear sheet of I the backheadatfitsuppegend through theilange Fuel may -bveconvenie tly delivered fromA thev sourcer .of supply to the firing openiifigV by aseo?- tional'serew-conveyor comprising a screw section r2li in the transfer vconduit I6 and ascrew sectioiijfl intheYriserconduit I8.

driven trom anjengine24 of thevmulti-cylinder reciprocating type, which in the instance shown, is frigidly mountedrfrom the under side of the locomotive cab, deck A,I I( on 'thefleft' side portion ofthe locomotive andV above the foraine I1. The engine ,24, comprises an,A engine bed 25 havingside walls-26.7and ZTI, ,en dwalle 28 and 29` and a iioor 30, A cylinder block 3|isV securelyattached to anffend wall-otthe.enginebed, Theusual valve indersl32;` The cylinders 32v are provided with reciprocably mounted lpistons ',(not shown) arranged-to transmit power to a crank shaft 33,

mechanism (not shown) is employed, for conl f l trolling Ythe inlet and exhaust of steamto the cylmounted in the bearings 34 inthe side walls .26

and 21 of the engine bed 25.

The upper marginal edge'of the engine bed 25 35forming a cover for the engine bed 25. Bolts l 3B passing through the removable floor portion'33 and into the flange 35 bounding the opening 36 secure it in place, preventing coal dust from entering. the engine bed. To insure a. tight fit, a

gasket 40 may be inserted between the floor portion 38 and the anger35.V

Y The base casting 4I of the riserA conduit I8 hasA crank shaft 33 are providedwith the sprockets which' passes a1 4G and 41, respectivelygover sprocket chain 48.

By securing the engine 24 to the underside oi" the cabdeck Il and mounting the engnescylinders from an end Wall of .the engine bed,V access to the engine'for purposes of inspection andrepair is readily and convenientlyfmade possible by removing the floor portion 38 of the cabr'deck. At the same time, the engine is disposed so as to occupy only such space upontheiocomotive which heretofore hasnot been used to any; ad'- vantage. Y j g i The locomotivenunit of the Stoker lrsinceit is supportedfrom the locomotiveboiler backhead, is free to move with the backhead asthe latter expands and contracts-A` Likewi'sej since A the stoker engine 24 is rigidlyl secured tothe deck i I Whichis attached to the boiler backhead, italso is free to move with the fbackhead.
