Many other conflicting requirements could` be mentioned. rihese requirethe railroads lead to the design of manyI diderent types of stokers and complications in their installation with a resulting complicity of locomotive and tender construction.

My present invention permits compliance with the conflicting requirements without the complications of past practice and the invention contemplates designing the locomotive and its tender 'to best suit a desired Stoker mechanism and wherein the Stoker conduit system is incorporated as an integral part of alocomotive and tender structure.

lReferring now tothe drawings, Figures 1 to 4 illustrate a preferred form of construction selected for the vpurpose of best de scribing the invention, although, it will be recognized by those familiar with locomotives that under certain conditions, or design requirements specified, any of the other forms shown may be preferred, or still others not shown may be employed and be within the spirit of this invention.

A On the drawings and referring now particularly to Figures 1 to 4, the locomotive is generally represented at Anthe tender as a whole at B, andthe articulated coupling gear interposed between as at C. Fuel is carried from the tender and fed to the locomotive by suitable mechanism, hereinafter described, through a exible conduit system indicatedgenerally at D which comprises a rearward trough section E .formed integrallyA with the tender structure, a forward tubular or delivery section F formed integrally with the locomotive structure, and' a telescoping conduit section G separable from the locomotive and tender and which flexibly joins the rearu ward and forward conduit sections incommunicating relationship in a manner to per-1 mit articulation between the locomotive and tender without breakage of the conduit sections or any of its associated parts. All of these parts vand Athe particulary locomotive 'and tender construction are hereinafter more specifically described.

The locomotive A is of the usual construction except in that part to which this invention is directed. lt includes a frame 10 and a boiler and iirebox 11 having an upstanding backhead 12 at the rear thereof. rllhe tirebox is provided with the customary grate as at 13. The locomotive cab is represented at 14 and its deck or floor indicated by the numeral 15. The tender B rearward of the locomotive is formed'with an under frame 16 above which there isa body portion including'a fuel bin 17 and a water compartment 18 separated from each other by the side slope sheets 19 and 20, the rear slope a gear housing compartment 26 which is formed by the top Wall 27, the rear vertical wall 28, andsidewalls 29 and 30.

The sidewall 30 extends to the forward end of the tender and forms with the support 24: and the frame 16 a longitudinally extending compartment 31 open at its forward end and at its rear end opening into the gear housin compartment 26. The compartment 31 ena les inspection or maintenance of the vdriving gears 32, 33 and the trough drive shaft 34 of the stoker mechanism. ein additionalinspection opening 35, see Figure 1, is provided in the under frame 16.

An upstanding wall 36 transversely of and being'cast withthe under framel is arranged to partially close the front end of the V-trough 22 andvtov servev as the forward wall for the water compartment beneath the tender deck 37. An opening 38 is provided in this wall for the passage of fuel forwardly from the trough.

Horizontally and inwardly extending ldges 39, 40, are provided at the upper end of the trough 22 to form a seat for slidable plates 41, which form a continuation of the tender deck. The sides of the trough ,22 extend upwardly as at 42, 43, to receive the side slope sheets 19 and 20, which sheets are held thereto by welding orriveting in any suitable manner. Likewise the rear slope sheet 21 is attached to the top wall 27, ofthe gear housing compartment 26.

Thus it will beseen the rear and side slope sheets together with the trough formation of the underframe divide the fuel and water compartments in a manner to greatly simi plify tender construction, reducing construcwith a projection 45 detachably secured' to the front-wall 36 in communication with the opening therein and formed with the projection 4:5 is a spherical ange 46 adapted to be wardiend a spherical ball cooperating with a. horizontally split spherical liange 5l on the rear end of the rearwardly extending portion 52 of the forward conduit section F, and

forms a flexible section between the forward and intermediate conduit sections.

The forward conduit is formed integrally with a new and novel mud ring 54. As best shown in Figures l and 4, the conduit F extends through the plane of the backwall 12 and has a forward mouth portion 53 extending into the iirebox and opens upwardly therein to deliver fuel at a height above the normal level of the lire to a distributor 55 disposed in any suitable manner in the back of the mouth portion substantially at the rear of the fuel stream being delivered. This mouth portion is protected from the heat of the fire by an upstanding perforated protecting wall 56 horizontally split and partially surrounding the mouth portion. The protecting wall is supported on the center gra-te bar 57 of subs antially Wishbone shape or a form well known in locomotive and Stoker construction.

r1Ehe novel construction of the mud ring 54 together with its integral :feed conduit section is clearly illustrated in igure 4 read in connection with Figures and 2. yl-he mud ring may be of the usual construction mad in the form of a unitary casting hounding the hare of the iirebox., or as conventionally illustrated in Figure 4 it may be formed of four straight sections welded er otherwise attached at the corners and which the transverse rearward section 6G has formed centrally therewith, the forward feed con- A duit section F. ln this transverse section there is an upwardly extended ring portion 6l of channel section having an archway or opening therethrough at 62 which as will be seen from Figure l forms the hand tiring opening of lthe hackwall. Beneath this opening and interposed between the upright sides of the extended ring portion is disposed the conduit section F in such manner as to form with the mud ring proper a durable striu1n ture. A cross 'wall 63 extends laterally about the tubular conduit portion 52, connecting the upright sides of the ring portion to form a closure beneath the opening 62. rlhis wall alf'o serves to tie the conduit and mud ring together. A horizontally disposed wall A64 extends rearwardly from the mouth portion 53 of the conduit to the upwardly extending sides of the ring portion and merges therewith to form a closure to prevent loss of fuel and to prevent the flow of excess cold, air into the ireb'ox at the base of the firing opening or archway. rlhis wall also ties the mouth portionof the conduit with the ring like extension of the mud ring to form a solid structure. Any suitable number of strengthening ribs as at 65,66, may b e provided to further aid in the construction of a well built and durable mud ring and stoker feed section.

Deck supports 'as at 67 and 67a are formed integrally with the rearward's'ection 52 of the conduit F, extending upwardly therefrom forming a solid support for the deck l5 as best shown in Figure l. rlhis arrangement supports the deck at a point where in past practice it has been found dihcult to firmly brace the deck from the backhead.

In` constructing the irebox and particu-4 larly, the backhead, the inner and outer sheets are apertured centrally and from their lower marginal edges, this aperture is substantially an inverted lul-shape in form and in alignment with the inner margin of the extended ring portion 6l, of the mud ring. rl`he sheets can be secured to the mud ring and its ring portion by riveting and welding or in any customary manner. as shown in Figure l a tiredoor ring 68 having an opening there in corresponding 'to the opeiun@q 62 of the inurl ring can be attached to the backhead in alignment with the firing opening provide a base for any conventional style of iredoor, not shown.

lhis novel mud ring structure stalled with a boiler iireboheures e and Hrm backhead andin '.hicl any p" ferred *form of stoker feed conduit can formed integrally therewith to deliver fuel to the iirehox at any desired elevation, and either within the irebox as sb Figure l, or eateriorly 'thereof a charged through the cpering 82 as shown in the modification illustrated in Figures 5 to 7 as later .explained Suitable mechanism is empoye ing and for conveying fuel through the condu system D and distributing the tire. For this purpose there is por" a screw conveying means including section 70 disposed within the trough E, and at its rearward end operatively connected with the gearing 32, 33 through a gear shaft 7l; a section 72 mounted within the conduit G and universally connected as at 73 to the rearward section; and a forward screw section 74 in the conduit F flexibly connected as at 75 to the intermediate section and at its forward end terminating short of the upturned portion 53 of the forward conduit section. This screw conveying means is driven from a motor 7 6, see Figure 2, mountedon the locomotive and operatively connected with the trough gearing through a flexible and extensible shaft 77 universally connected at its one end at 78 to the motor aud at its other end at 79 to the trough drive shaft 34 mounted in the bearings 8O or" the trough structure. A Crusher member 8l is mounted above the i n uw screw section 7 0 within the trough E in a position to actupon the fuel as it is being ad trough E and is conveyed forwardlyv through the conduit system by the screw sections 70, 72 and 74, driven at desired speeds from the motor 76. The fuel rises fromv the forward end of the screw section 74 through the mouth or delivery conduit portion 53 into the path of a distributing steam blast adapted toxissue from the distrbutor 55 and is spread in aerial paths over the grate 13. Obviously, the arrangement of the stoker drive and the conduit system permits of movement between the locomotive A and the tender-B. 'l

It will be recognized from. the foregoing description of the preferred form of my invention that a very desirable construction of stoker fired locomotive and tender is provided wherein the Stoker mechanism is of an extremely simplified form and in which the fuel may be conveyed from the fuel bin of the tender and delivered to the firebox in a most direct path with a minimum of handling,r

and consequently a minimum of grinding or pulverizing of the lump fuel.

A modified form' of the invention is illustrateddn-Figures 5 to 7 inclusive, in which' the tubular section 82 of the forward conduit F is. entirely outside of the firebox 11 and through which the fuel is raised by' any suitable means to a sufficient elevation for s reada firing opening through the backhead 12 is provided above they rearwardly extending conduit section 82 which is integrally formed with the mud ring. In this construction, as shown in Figure 7, the inside sheet of the firebox backwall is of the same form as that used in present practice and having an aperture therein corres onding to' the opening through the mud rlng to provide for hand firing, whereas, the outside plate will be the same as that used in the construction of the preferred form. The rear. crosswall 88 of the mud ring extending between the upright sides of the ring member and constituting a closurebelow the feed conduit extends horizontally at its upper end to form the bottom of the firing opening and it meets with the inner sheet v-to form a chamber 89 through which the boiler water may circulate entering through theapertures 90. of the ring portion.

A. nsaaeae.

In this form of the invention the delivery or floor portion 84 is Adetachable from the conduit section 82 and is secured thereto in the seat 91 by suitable bolts as at 92. The distributor head 88 projects upwardly through the floor of the conduit section 82 rearward of the backhead 12 and at the rear of the delivery portion 84, there the fuel is swept forwardly into' the frebox. Bothv the delivery member 84 and ,the distributor 83 cooperate in scattering the fuel uniformly over the fire.

This modification of the invention discloses in effect an outside feed conduit system, the forward section of which is formed with the mud ring and wherein the forward or delivery portion that extends into the firebox and subjected to the heat thereof is replaceable and can be detached from the mud ring structure. This form of the invention 'also has cast therewith deck supports as at 93, 93a, extending laterally from the conduit F to rigidly support the deck 15.

Making the forward delivery or mouth portion of the stoker conduit replaceable is an important feature of myinvention and in Figures 8 to 10 of the drawings, the form of feed systemy illustrated in the Figures 1 to 4 is shown, but wherein that portion of the forward conduit section that extends into the firebox is so constructed that it may be removed, replaced 'or renewed.

Referring now to these figures the forward conduit F is formed of two sections, a rearward section 95 formed integrally with the mud ring and extending rearwardly therefrom; and a forward delivery or mouth section 96 in effect a continuation of the rearward conduit section, but which can be detached iffound destroyed by the heat of thefire or if worn by the passage of the fuel therethrough. The mouth portion has formed therewith a laterally 'extending flange 97 which when applied is received in the seat 98 formed by the U-shaped lug 99 disposed vertically on the wall portion 63 of the mud ring structure. As shown the forward section 100 terminates ,at or a little short -of the detachable section of the conduit toA permit this portion to be removed or replaced without the necessity of taking apart4 or breaking down the Stoker mechanism.

If desired, the forward screw section can be extended into the mouth portion and the replaceable section can be renewed merely -by disconnecting the locomotive and tender and separating them a sufficient vdistance 4to move f the vforward end of the screw rearwa'nd of the juncture of the two conduit sections 95 and 96 to permit the section 96 to be lifted out of itsposition. Otherwise, the Vconstruction shown in these figures is identical with that described in Figures 1 to 4. v

Figures 11 and 12 on the drawings illustrate a somewhat difl'erentaspect of the invention wherein the forward conduit sec- Lerares tion F is formed integrally with the frame work of the locomotive.

In these :figures the locomotive A is equipped with a conventional boiler iirebox 101 having its component parts of conventional form. Ihe frame structure includes a cradle casting 102 at the rearend portion of the locomotive. In the broader aspects of this invention it is immaterial whether the conduit F as shown in Figures 11 and 12 be formed integrally with the main frame, one of its members, or with the cradle casting as specifically disclosed in the drawings, but for the purpose of illustrating the various modifications of the invention the conduit is shown as b eing formed with the cradle casting. The conduit F in this modification of my invention comprises 'the integral section 103 and an upwardly 'extending replaceable delivery or mouth section 104. The replaceable section extends loosely into the iirebox but is supported in the seat 105 in the forward curved portion of the integral section. The forward screw section 106 terminates at or adjacent this curving portion and forces the fuel upwardly through the replaceable section into the zone of action of the distributing blast issuing from the distributor head 107 actin to spread the fuel over the fire as is wel known in practice, The replaceable conduit section is protected from the heat of the fire by a protecting grate wall'56 of identical form to that shown in Figure 1. Any suitable cast construction can be employed for forming the conduit section 103 of the forward conduit F with the frame or cradle casting 102, but for this purpose there is shown a rib structure generally indicated at 108.

It isbelieved apparent from the drawings and description that my invention provides a greatly improved Stoker-fired locomotive and tender construction of practical utility and one in which the construction is such as to be designed to incorporate the stoker feed conduit or its major sections as an integral and essential art of its structure with a consequent simpli cation in design, resulting in a reduction in weight, lowering of production and maintenance cost, and offering a more durable and rigid construction:

The specific illustrations shown 1n the drawings and corresponding specific descriptin herein are used for the purpose of disclosure only, but it will be realized that the substance and spirit of the invention ma be embodied in other forms as well as t ose shown.
