This invention relates to locomotive tenders of the class equipped with Stoker mechanism. The primary object is the provision of an unusually long tender of the character described.

In past practice, most of the tenders for Stoker fired locomotives were provided with a cast steel screw conveyor mounted in an open mouth trough for advancing the fuel from the bunker to a conveyorrleading forwardly from the tender to the locomotive. The length of the cast screw permissible with satisfactory operation is an Yirnportant factor in the design of tenders, particularly so on those transportation systems where the trend of the design is toward the adoption of longer tenders with greater fuel carrying capacity than those now in service. One design considered contemplates the use of a stoker conveyor approximately 25 long which is about double the length of the conveyors of past use. Many problems apparent to those skilled in the art arise in connection with the use of such a conveyor.

This invention seeks to meet the problems by the provision in a locomotive tender of a stoker conveyor comprising a plurality of sections disposed under the fuel bunker and arranged with the delivery end of one of the sections being positioned above the receiving end of another. In one embodiment of the invention, as will presently appear, the stoker conveyor of the aforesaid construction is adapted for use with a fuel bunker having a plurality of discharge outlets disposed in diiferent elevations.

Many specific objects and advantages of the invention will be apparent from the following description when read with the accompanying drawings, in which,

Fig. 1 is a vertical longitudinal central sectional view of the locomotive tender of the invention;

Fig. 2 is an enlarged vertical transverse section taken on line 2 2 of Fig. 1;

Fig. 3 is an enlarged vertical transverse sectional view taken on the irregular line 3 3 of Fig. 1;

Fig. 4 is a view similar to Fig. 1 representing a modied form of the invention;

Fig. 5 is a vertical transverse section taken on the irregular line 5 5 of Fig. 4; and

Figs. 6, '7, 8 and 9 are enlarged vertical transverse sectional views taken on lines 6 6, 1 1, 3 8 and 9 2, respectively, of Fig. 4.

On the drawings, Figures 1 to 3 inclusive, illustrate the invention embodied with a tender of the type wherein a separate compartment under the bunker is provided to receive the stoker conveyor. For purposes of description, this construction will be referred to as the preferred embodiment of the invention, although the structure illustrated in Figures 4 to 9 inclusive, may be preferred in service because additional water space is provided by placing the stoker conveyor as shown within the water compartment.

Referring to Figures l to 3, the improved tender as a whole is represented at A. It includes the underframe I above which is formed the water compartment I I and the fuel bunker I2 separated by the rear and side partition plates as at I3 and I4 respectively. Extensions I3a and la of the rear and side partition plates form with the imperforate wall I of the underframe, a Stoker conveyor compartment I B. This compartment is separated from the fuel bunker by the horizontally disposed oor I 'l consisting of rearward and forward sections I'Ia and Ilb respectively, which are arranged in different elevations. Preferably, the rearward floor section is positioned in a horizontal plane above the forward floor section. Their adjacent ends are connected by an upstanding wall IB extending transversely thereof. Suitable brackets as at I9 and support the floor sections from the partition walls Ida.

The floor sections are centrally apertured at 2| and 22 respectively. The two constitute a downwardly opening discharge outlet in the bottom of the bunker. From another aspect of the invention, the apertures 2I and 22 may be considered as fuel bunker discharge outlets disposed in different elevations. Discharge of fuel through the apertures or bunker outlets, is controlled by slidable plates 23 which are well known in practice, but which never before have been disposed in series arranged in different elevations. The slidable plates of the forward floor section Ilb are carried in the seat 24 formed by any suitable construction of plates or bars on the underside of the floor; and similarly, the slidable plates of the rearward floor section are carried in the seat 24a. The plates are pulled forward one at a time to provide what may be called a shiftable opening as at 22 in Figure 1. As the fuel recedes in the bunker the rearward plates are pulled forward in succession.

It will be observed that the forward slide plate 23a of the rearward floor section I'Ia when pulled forward hangs over the wall I8 and rests in an inclined position upon the rearmost plate of the forward oor section. A lug 25 depending from the forward slide plate 23a engages the wall I8 and restrains further continued forward movement of the plate and its acts also to maintain the plate in the inclined position as shown conventionally in Figure 1.

Fuel passing through the bunker discharge outlet is received by a stolzer conveyor indicated as a whole by the letter S` This conveyor is mounted in a fixed position on the underframe EEB beneath the fuel bunker I2 in the conveyor compartment I6. It may be formed of any desired number of i.

oifset sections, but preferably, it comprises the rearward section 25 and the forward section 21".

These sections are made in tne form-of4 troughs, as best shown in Figures 2 and 3, and Yare disposed with the delivery end portion 26a-of the rearward trough section positioned above the receiving end portion 21d of the forward trough section; The trough sections are shown disposed in horizontal planes one higher than the other, but it will. be recognized the one or both of them may be `placed in an inclined position vif desired.

Preferably,l the rear trough section 2B is mounted closely adjacent and directly beneath the bunker iioor section Ila', vand similarly,` the forward trough section 21' is disposed under the forward floor section 'i 1b; 1 TheV adjacent ends of the trough sections are offset frornrone' another and the rearward troughsection is-'provided with the downwardly opening passage- '2d-'communicating with the.receiving portion 27a of the forward trough section at 'a pointrearward of or directlyy adjacent tothefwall -I8 between thebunker iioor sections;

In this embodiment-of the invention the trough f-Isectionsare'- constructed-as separate units with thesectionvZT carriedbythe underframe i@ and thesection A26secured in an elevated position to the floor-section` Ha. Any suitable fastening membersmay be employed Vfor holding the sections in their respective positions. Each unit or trough section'containsa -screwasat Q9 and-3%, which l"screws serve to ladvance fthe=fuelthrough the stokerconveyor-to 4a Itransferl conveyor 3l leading forwardly from theftender.- The rearward end ofthetransfer conveyor 3 |.is `universally connected at 3la to theforward end of the deliver-y or forward trough "section V2li mounted over the forward end portion of the screwlloooperates witlrthe-screwto break down lumps of` fuel too large forfiring. Thesorews 2Q,

30' are of substantially the same length 'which is notl inexcessofthat determined-by practice to operate satisfactorily without bending or-break ingand such that requires no bearings intermediateI the 'ends of thescrew;l In -longertenders more thanytwo separate screws maybe found necessary.v Thel use'ofv the separated screws is made possibleby theprovision of the trough 'sections disposed in'different elevations.y

Suitablefmeans is provided for driving the-screws 29."and- SQ'from' their rearward ends. Forl this purpose'a gear drive is mounted-.at the rearward end of each-trough sect-ion in housingsiand'.v

The screw- 30is connected-- to vthe -shaft- 353 which carries a gear yr-fmeshing withthe pinion {il} on thepinion-shaft 35i'. This shaft is connectedto Va power, shaftl 39* extending forwardly to a prime mover,not "shown:A The gear shaft 35 extends rearwardly from the housing 3d and isuniversally rconnected-to the drive-shaft 5mi-which at its rearwardlendis universally connected to la gear shaft'l-y Thisshaft carries a Agear 52. .meshing within the housing 33 with a similar gear 43 fixed on the-shaft'A 44- which lis operatively connected .to the Vrearward end-of the screw'f-ZQG Hence, mo-

tion imparted by the power shaft 3S will be transmitted through the gear drives to the screws.

The forms of the invention described above is particularly applicable where it is desired or necessary to form the Stoker conveyor in separable sections disposed in the customary conveyor com# partment. The use of this construction is made possible by forming the tender with thelfloor sections disposed in different elevations as heretofore described. Figures 4 to 9 inclusive, illustrate a modification of the invention now to be described. It employs the important feature of the preferred form of the invention, in that the Stoker conveyor, mounted beneath Vthelounker, is composed of sections disposed in different elevations and offset at their adjacent ends. In this modied form the conveyor sections are formed as an integral structure mounted beneath the fuel bunker in the water compartment of the tender. By reason of forming the sectionsras an integral unit-andplaoing the unit in the waterlcompartment, a compact structure is provided such that in lmany instances` it will not be necessary to vconstruct the floor of the bunkenof sections disposed in different elevations asfin the preferred form of the invention.-

Referring to the aforesaid figures, the improved` tender -is represented asia whole at B. Above thel waterbottom underframe't, the fuel bunker 45 f '30 by'side .partition plates l; and the rear plate 4E,- secured at their lower marginal edges in any suitand the water compartment '36a .are separated ableimanner to thestoker `conveyor Vindicated generally at 49. Theconveyor is an integral unit mounted-lin the water .compartment to contact the water therein and. arranged .to `provide for passage `of water from one side of the tender to the other. Itmay be/cast integral with `the uncast unit mountedon. the frame. endof the conveyor unit lis formed in any de.- sired manner with the front wall of the tender to1form a closure forthe water compartment.

Likein the preferred form of theinvention, the

stoken l.conveyor is composed of a plurality of secl v derframebut preferably, it is built as a separate Y The forward..r

tions; The rearwardgsection 53; ispositioned in a Y horizontalrplane in a level above thereceiving end. of theV forward .sectiong l; which is/inclined forwardly from a point below the delivery end `of the.

rearward section. A wall 52 unites the adjacent ends of therearward and forward sections. Eachy section isfmade in the form of a troughopening upwardly to communicatev with the fuelY bunker. Discharge of fuel from the bunker -in to either trough section is controlled by a series of slidable plates 53 positioned horizontally `inthe seat 5;

formed along the upper marginaledges of the,

VerallyYeXtending ledges 5E which in effect f orm a floor for the fuel bunker which iioor is apertured as at 5T. 'immediately above the trough forma- Y tions of the conveyorunit.

The conveyorscrews 58, and 59 of substantially theV same length are mounted respectively in the The forward end of screw 58. extends over and above the 'rearward end of the., screw 59 vwhereby the ,fuel conveyed along. thelrearwardtrough section ffwill be discharged downwardly in-to the receiving end portion; of @the forward. trough sectionl; on ,to the CTI screw 59 which advances the same forwardly beyond the crusher 60 to any suitable mechanism for transferring the fuel from the tender to the locomotive, not shown.

'I'he screws 58 and 59 are driven from their rearward ends by gearing disposed in a water tight housing 6| formed at the rearward end of the stoker conveyor 49 and extending downwardly through the underframe 45. A bracket structure indicated as a whole at 52 mounted underneath the underframe and extending to one side thereof forms a laterally extending continuation of the housing 6I and opening through a side of the tender. The bracket structure carries the prime mover or stoker drive engine B3. An endless chain 64 imparts motion from the prime mover to a sprocket 56 on the pinion shaft 51. This shaft carries a pinion 68 in mesh with the drive gear B9 on the shaft 'Hl which is operatively connected to the rearward end of the screw 53. Another` pinion l! is also carried by the pinion shaft 51, which last named pinion engages the gear 'l2 fixed on the drive shaft 73 which extends forwardly to a point within the forward trough section 5l where it is connected by a universal joint 'M to the rearward end of the screw 59. The aforesaid gears and pinions are journalled in a box 'l5 which is mounted on the rear transverse wall 'I6 of the stoker conveyor unit 49 in a manner to form a water tight sleeve therewith. A bearing 'I1 carried by the wall 52 supports the forward end of the drive shaft 13. This shaft is protected from the water of the water compartment by the sleeve 18 which surrounds the shaft and extends between the wall 52 and the rear wall 16.

From the foregoing description it will be recognized that the screws 58 and 59 are driven from their rearward ends by the primemover and the gear drive both of which are mounted in the water tight Yhousing 6I at the rear of the conveyor unit.

In order to deliver the fuel at a point forward of the joint 'lll in the forward trough section 5i a removable iioor member 80 is pro-vided as an overhanging extension of the rearward trough section 55. This floor member may be held in position by welding or any other suitable means.

'While the two trough sections are shown as formed in an integral unit, it will be understood that they may be formed separately as in the preferred form of the invention or in any other desired manner such that will serve to arrange the sections whereby the delivery end of the rearward trough section is disposed above the receiving end of the forward trough section at a point beneath the fuel bunker. Various other changes and modifications of the invention may be made without departing from the scope of the appended claims.
