Incorporated, a. corporation ofv Delaware Application April 26,'V 1930, SerialNo. 447,451 Renewed August 12, 1933 7 Claims.

My invention relates to railway rolling stock and appertains to improvements in the construction of-tenders of Stoker-'fired locomotives.

-In tenders of this character it has heretofore -5 been customary to mount the Stoker fuel trough on'the tender in a specially provided compartment formed between the fuel and water compartments, the fuel trough bei-ng a unit separate from and forming no part of the tender construction, but being disposed in the compartment provided therefor in a position to receive fuel from the coal bin or fuel compartment; consequently, complicating the fabrication of the tender and materially reducingits water carrying capacity. :My present invention has for its main object to dispense with the necessity for the special trough compartment and the separate trough, and at the same time, to provide a novel and improved tender K construction `simplifying the fabrication and affording increased water space without sacrificing fuel space.

More specifically, I contemplate vthe provision of a novel and improved tender wherein the Stoker fuel trough may be formed' as a function- "22.5 ally integral part of the tender tank walls forming the fuel and water compartments and wherein novel supporting means is provided to support the fuel trough from the tender underframe to permit the use of the space'beneath the troughfor water space.

A further object of my invention consists in the provision of a novel locomotive tender trough having formed therewith a water tight gear hous- 5 ing compartment, and a Water tight drive shaft casing communicating with the gear housing, with or without a fuelcrush'er formed as an integral part of the trough.

Another object of my invention consists in the o provision in a locomotive tender trough having a drive shaft casing formedv therewith, of a jointed shaft in the drive shaft casing and novel means for preventing longitudinal movement -of the shaft.

Another and important object of my invention is to provide a-more rigid, simplified tender construction, reducing construction and maintenance costs.

The foregoing and other objects and advantages will appear from the following specification.

Referring to the accompanying drawings, in which K.

-Fig. 1 is a central longitudinal vertical Vsection of aportion of a locomotive tender showing a "part of 'the' Stoking Annchanis'rn;

Fig. 2 isa plan View partly broken away of the structure shown in Fig. 1; and

Fig. 3 is a vertical section taken on the line 3--3 of Fig. 1 in the direction of the arrows.

The tender of a locomotive is generally indi- 60 cated at l0, its deck at 11 and its underframe at 12. The fuel bin is designated at 13 and the water space at 14. The fuel bin 13 is formed by the rear slope sheet 15 and the side slope sheets 16 and 1'7.

The floor 18 of the bin is provided with a 65 central vlongitudinal opening 19 communicating with the trough 20 and through which fuel is supplied to the trough by gravity. Plates 21 are slidably mounted in the opening 19, and may be moved from covering position to permit the entry 70 of fuel into the trough 20 as the supply becomes depleted.

The forward end of they trough 20 is equipped with a projection 22 detachably secured to the front wall 23 of the trough and communicates 75 with a restricted opening in -said front wall. Formed with the projection 22 is a spherical flange 24 adapted to be received in a spherical portion of the vertically split coupling member 25 carried' by the tubular section 26 which leads for- 80 wardly to deliver fuel to the locomotive rebox in any desired manner.

Suitable mechanism is employed for crushing and for conveying fuel, including a screw conveyor 27 mounted in the trough 20 and extending 85 forwardly through the projection 22 and spherical flange 24, a conveyor screw 28 in the tubular section 26 flexibly connected with the screw 27 as by a universal joint 29, and a crushing abutment 30 formed integrally with theforward wall 90 23 of the trough and above the discharge opening thereof for vengaging the `fuel to crush it to a proper size for firing.

The trough 20 is a unitary casting, preferably steel, and is substantially U-shaped, it may however, be V-shaped, ormade to assume any other suitable shape or design. The sidewalls 3l of the trough have a beveled surface 32 underlying the bin floor 18 adjacent the opening 19, and the plates 21 havetheir side edges formed to a corre- 100 spondingbevel 33. By this arrangement the bin floor 18 and the sidewalls 31 cooperate to form -V-shaped guideways for the plates 21 and there is no tendency for the fuel to collect Von the supporting surfaces 32 for the plates. Formed with 105 vthe sidewalls 31 of the trough are the flanges 34 underlying the bin floor 18 and the slope sheets any other suitable manner to form a water tight joint. Likewise the rear slope sheet 15 is secured to the flanged portion 37 of the rear wall 38 of the trough. Similarly, at the forward portion of the trough, the laterally extending integrally formed flange 39 is secured to the bulkheads 40 and 41 beneath the deck 11 and together with the plate 42, which is secured along its upper margin to the flange 39 and along its lower margin to the underframe 12 and extending between the bulkheads 46 and 41, forms a closure for the water space 14 at the forward part of the tender.

The screw 27 is adapted to be operated through gearing 43 located in the gear housing 44 at the rear of the trough from a suitable source of power, not shown. The rear wall 38 of the trough forms one of the sidewalls of the gear housing 44 which is formed integrally with the trough. The gear housing 44 is provided with a removable cover plate 45 secured to the housing through water tight joints. The cover plate 45 may be secured to the housing 44 by a suitable number of studs or bolts, as at 46, and a rubber gasket or a gasket of any other suitable composition may be used between the adjoining machined surfaces of the housing and cover to effect a water tight joint.

A water tight casing 47 is formed integrally with the trough 20 and opens at its rearward end into the gear housing compartment 44. The rearward end of the housing 47 forms a bearing surface 48 for the rearward portion 49 of a jointed shaft 50 disposed within the casing 47. The portion 49 of the jointed shaft 50 carries a spur pinion 51, which engages a corresponding gear 52, on the shaft 53 of the screw conveyor 27. The forward portion 54 of the jointed shaft 50 carries a coupling member 55 on its rearward end forming a driving connection with the shaft portion 49. The forward end of the casing 47 isr closed by the member 56 which forms a bearing for the shaft portion 54. The member 56 may be secured to the casing 47 by means of bolts 57 or by any other suitable means. Any tendency of the shaft portion 54 to movev forward is prevented by means of a collar 58 secured to the shaft portion 54 adjacent the member 56. The shaft portion 54 may be readily removed throughthe forward end of the casing 47 by removing the bolts 57. The member 56 is also removed leaving an opening in the forward end of the casing 47 large enough to permit the coupling member 55 to go through. The shaft 50 communicates with a suitable source of power, not shown, through the telescoping shaft 59 connected to the shaft 50 by means of the universal connection 60.

Forming the gear housing compartment 44 and the casing 47 integrally with the trough provides a more rigid, durable and simpler construction and increases the available water space on Vthe tender. The number of movable parts is considerably decreased, minimizing replacement and maintenance costs of parts that can get out of order.

The trough 20 is supported from the tender frame 12 by the foot members or supporting brackets 61 and is secured thereto by the rivets 36 which pass through the bin floor 18 and flanges 34. The foot members 61 comprise headers 62 and base plates 63 which extend longitudinally the length of the trough. The header and base plate are joined by transverse plates 64 spaced at intervals throughout the length of the header and base plates. The plates 64 on one side of the trough are provided with the recesses 65 to provide for the casing or drive shaft casing 47.

Joining the faces of the plates 64 and perpendicular thereto are plates 66 extending from the header 62 to the base plate 63. The plates 66 are provided with the openings 67 to permit circulation of water in the water space beneath the trough.

Fastened to the edge of the plates 64 are the baffle plates 68 which prevent the surging back and forth of water in the water space of the tender.

From the foregoing it is believed those familiar with locomotive tender construction will recognize the advantages of my invention and will realize that it permits of installation and conversion of hand fired to stoker fired engines to particularly good advantage as well as being useful and desirable in newly constructed tenders.
