My present invention relates to railway rolling stock and appertains particularly to locomotives and tenders equipped with mechanical stokers. The main purpose of the invention is the pro- 5 vision of an auxiliary tender behind the usual tender and the provision with such tenders of conveying mechanism for advancing fuel therefrom to the locomotive.

Specific objects of the invention reside in the novel tender structure and in the arrangement of and the relation between the conveying mechanism on the main and the auxiliary tenders as disclosed by the accompanying drawings, in which Fig. 1 is a longitudinal vertical section on the median line of the locomotive and its main and auxiliary tenders of the invention with the conveying mechanism therefor shown partly in elevation and partly in section;

Fig. 2 is a similar view of the main and auxiliary tenders illustrating a modification of the invention, and Fig. 3 similarly illustrates another modification of the invention.

The preferred embodiment of the invention is illustrated by Fig. l of the drawings. Referring to this figure, the locomotive is indicated at A, the main tender at B, and the auxiliary tender at C. As is customary, the locomotive and its main tender are coupled together by the conventional coupling means at I and a similar coupling connection is provided at II between the main and the auxiliary tenders. Thus, the three units are intercoupled to permit of the necessary articulation between them to meet service conditions.

Fuel is carried from the main tender to the flrebox I2 of the locomotive by the stoker conveyor represented generally at I3 which includes a rearward trough section I4 mounted in the conventional Stoker trough compartment I5 beneath the apertured floor I6 of the fuel bunker I1.

In the broader aspects of my invention the fuel bunker and the stoker compartment in the preferred and modified constructions constitute a fuel compartment separated by partition plates 4') from the water compartment.

The flow of fuel from the bunker intothe trough is controlled by slidable plates I8 which, as is well understood in the art, are shiftable 5o longitudinally in the fuel bunker floor. From the trough the fuel is advanced by the sectional screw I3 forwardly through the intermediate conduit section 20 and thence through the forward conduit section 2| to the distributor 22 disposed at the firebox firing opening 23. In the device (Cl. 10S-234) shown, the trough and the forward conduit sections are mounted rigidly in any suitable manner and the intermediate conduit section is composed of telescopic portions lat their remote ends being universally jointed as at 24 and 25 respectively to the trough and to the forward conduit section. It will be understood that the screw I3 similarly consists of three sections universally connected together in the vicinity of the conduit joints 24 and 25.

The screw I9 at its rearward end is coupled in any known manner to the gear 26 which is driven by the pinion 21 on the pinion shaft 28 which in turn receives power from the rigid drive shaft 29 and the flexible and telescopic shaft 30, the latter being operatively connected to the motor 3| located on the locomotive.

After the fuel has been removed from the fuel bunker I1 of the main tender the locomotivev is then red with fuel stored in the fuel bunker 2 32 of the auxiliary tender C. The fuel from the auxiliary tender is carried forward to the fuel bunker I1 of the main tender and from there it is advanced to the locomotive by means that now will be described. From the bunker 25 32 of the auxiliary tender the fuel passes through the apertured floor 33 into the trough 34 disposed thereunder in the water tight compartment 35. The ow of fuel from the bunker 32 into the trough 34 is controlled by the slidable plates 36 which are shiftable as heretofore explained in connection with the slidable plates I8 of the main tender. The trough 34 is universally connected at its forward end as at 31 to one end portion of a two part telescopic conduit 38 extending forwardly to the rear wall 33 of the main tender from which wall it is universally supported by the universal joint construction 40, the member 4I of which is xed In any suitable manner to the wall 39. A tubular pipe or conduit 42 at its rearward end opens into the conduit 38 and is inclined forwardly and upwardly therefrom to and opens forwardly through the rear slope sheet 43 of the main fuel bunker.

It will be observed that the conduit 42 is disposed in the water compartment D of the main tender and therefore, a water tight joint of any suitable construction is formed at its end portions. In other words, the conduit is made water tight and so fitted in the tender that there will be no leakage of water from the water compartment. The fuel is carried forward from the trough 34 through the conduits 38 and 42 by a sectional screw 44 which is coextensive with the conduits and at its forward or delivery end dis- 56 charges the fuel into the main fuel bunker I1 from whence it falls by gravity or may otherwise be delivered into the trough I4 and from there carried forward to the rebox as heretofore explained. It will be understood, of course, that the screw 44 is universally jointed in the vicinity ofthe conduit joints 31 and 40.

Thej'screw 44 is operatively connected at its rear end "in any desired manner to the drive gear 45 which is driven from the pinion 46 by the rigid drive shaft 41. This last named shaft is operatively connected to the flexible and extensible shaft 48 extending between the main and the auxiliary tenders and the shaft 48 receives its motion from the shaft 49 which may be connected to or disconnected from the pinion shaft 28 by the clutch 50. That portion of the shaft 49 extending between the rear wall 38 of the tender and the rear wall 52 of the stoker compartment l is housed in the sleeve 5| which .is made water tight at its ends by welding or in any other suitable manner. Hence, it will be understood that by engaging the clutch 50 the screw 44 will be driven through its associate gears and shafting from the motor 3|.

When the locomotive with its main and auxiliary tenders is placed in service, the clutch 50 is out of engagement, as shown, and the conveying mechanism is operated to remove all of the fuel from the main fuel bunker |1 after which the clutch 50 is engaged to transmit motion as heretofore described, from the engine 3| to the screw 44 for the purpose of conveying fuel from the auxiliary fuel bunker 32 forwardly into the main fuel bunker I1 from which it is advanced to the locomotive rebox by the stoking mechanism 3.

In this preferred form of my invention the auxiliary tender C is interchangeable with the main tender D. Thus, when at times only one tender is needed, the tender B can 'be uncoupled from the locomotive and the auxiliary tender C coupled directly to the locomotive and its conduit 38 and drive shaft 48 coupled respectively to the forward conduit section 2| and the motor 3| to constitute a complete mechanism for advancing fuel to the firebox; or if preferred, the auxiliary tender C with its conduit section 28 and its drive shaft section 48 may be uncoupled from the main tender B without impairing the operation of the stoker mechanism of the main tender for moving the fuel forwardly therefrom to the locomotive.

While I have not shown how the water is supplied to the locomotive it will be readily understood that the water may be passed from the `water compartment E of the auxiliary tender through a hose connection (not shown) to the water -compartment D of the main tender from which it may be pumped or carried forward by an injector as is well known in the art'to the locomotive boiler.

In the modification of the invention illustrated in Fig. 2, the structure differs from that of the preferred construction in that the fuel from the auxiliary fuel bunker is carried forward to the locomotive directly by the conveying mechanism without first passing into the main fuel bunker. Referring to Fig. 2 the fuel from the fuel bunker 60 of the auxiliary tender B passes into the trough 6I the same as described in connection with the preferred form of the invention, and similarly the trough 6| is mounted on the auxiliary tender the same as in the preferred construction. Fuel in the trough 6| is carried forward by the sectional screw 62 through the flexibly mounted extensible and contractible conduit 63 from the end of which it is delivered into a receiving chamber 64 formed rearward of the backwall 65 of the main tender A'. From this chamber the fuel is advanced forwardly by the screw 1| through the water tight conduit 66 disposed in thecompartment 61 of the main tender A and through the conduit extension 66a forwardly into the trough 68 mounted in the water tight stoker compartment 68 positioned beneath the main fuel bunker 10. Any mechanism such as that shown inthe preferred construction may be employed to advance the fuel from the trough 68 forwardly to the locomotive.

As in the preferred embodiment of the invention the screw conveyors are driven from a prime mover located on the locomotive as shown in Fig. 1, but not disclosed in Fig. 2. The motor is suitably connected to the drive shaft 12 in the modified construction which shaft extends rearwardly from the compartment 69 through the water com,- partment 61, wherein it is protected by the water tight sleeve 13, to the pinion 14 suitably journalled in the housing 15 formed with the chamber 64. Motion is imparted from the pinion 14 to the gear 16, the shaft 11 of which is connected to and drives the screw conveyor 1|. Power transmitted by the shaft 12 is passed to thefiexible shaft 18 of the auxiliary tender B through the clutch 19 and from the shaft 18 to the pinion Ashaft 80 which carries the pinion 8| in turn driving the gear 82 for imparting motion to the sectional screw conveyor 62. Like in the preferred construction the conveying mechanism of the main tender A' may be operated independently. of the conveying mechanism of the lauxiliary tender B' because of the clutch 18. When it is desired to use the fuel in the auxiliary bunker 60 this may be done by engaging the clutch 18 and thus causing the fuel to be carried forward by the screw conveyor 62 in to the chamber 64 on to the screw conveyor 1| which functions to advance the fuel to the mechanism for carrying it 'forwardly to the locomotive firebox. It will be recognized that the conduit 66 and the sleeve 13 are formed water tight with the rear wall 65 of the tender and the rear wall 83 of the stoker compartment 69.

A still further modification of my invention is illustrated in Fig. 3. In this construction the engine for driving the conveying mechanism is mounted on the auxiliary tender and the screw conveyor sections are disposed in end to end relation throughout and are driven from the rearward end of the rear section. For this purpose the motor 90 is disposed in any desired location on the auxiliary tender 9| and is connected by the shaft 92 to the pinion 93 which drives the gear 84 connected in any desired manner to the rearward section 95 of the sectional screw'convey'or indicated as a whole at 96. The screw-section 05 is disposed in the trough 91 positioned the same as the troughs of the auxiliary tenders heretofore described.y From the trough 91 the fuel from the auxiliary tender is carried forward by the screw section 98 through the extensible and contractible conduit 99 extending between the auxiliary tender 9| and the main tender |00. The conduit 99 is universally attached at |0| to the trough 91 and is attached similarly at |02 to the rear end of the conduit |03. 'I'his last named conduit is water tight and is disposed in the water compartment |04 of the main tender. It communicates through the extension |03a with the trough |05 disposed in the stoker compartment |06 beneath the main fuel bunker |01. 'I'he screw section |08 is universally connected to the screw section 88 and serves to advance the fuel through the conduit |03, its extension |03a, and into and through the trough |05. Mechanism such as einployed in the preferred embodiment of the invention may be used to carry the fuel to the locomotive from the trough |05.

In operation of this embodiment of the invention the slidable plates 0 of the auxiliary tender 9| are positioned to close the aperture of the floor until all of the fuel has been removed from the main fuel bunker |01. When the main fuel bunker has been emptied the fireman then shifts the plates ||0 of the auxiliary tender to form an opening as at I2 to permit the flow of fuel from the auxiliary fuel bunker ||3 into the trough 91. With this construction the main tender can not be used independently of the auxiliary tender, although, the auxiliary tender may be coupled to the locomotive in place of the main tender |00 as will be observed from the described construction.

From the foregoing description it is believed apparent that in each form of the invention the conveying means of the auxiliary tender cooperates with the conveying means of the main tender to constitute a fuel conveying system extending between the fuel bunkers for advancing fuel from the bunkers to the stoking means on the locomotive; or from another aspect the invention provides a fuel conveying system extending from the auxiliary tender to the locomotive firebox for transferring fuel from the main and auxiliary bunkers to the rebox.

Those familiar with the operation of railway locomotives will recognize that my invention makes it possible to operate a locomotive for a greater distance and with less delay than is possible with the locomotive and tenders of past practice. It will be recognized too that my invention is particularly useful where locomotives are used in pusher service and when so employed it is possible to use the same locomotive for a greater period of time with less frequent delays for refueling.

While I have illustrated a number of embodiments of my invention still others may be utilized without departing from the scope and spirit of the appended claims.
