7 claims.

.This invention relates to locomotive tenders wlth means for moving the coal forwardly in the tender bin from the rear of the bin to the front, placing it within convenient reach of the fireman for delivering it to the locomotive iirebox.

It is an object of the invention to provide a novel, Simple, economical and eicient means for effecting the transfer of fuel from the rearward to the forward end of the fuel bin of a locomotive tender.

It is a further object of the invention-,to provide a novel tender arrangement wherein all the driving mechanism for the coal passer is conveniently located for purposes of installation, repair and inspection.

Other and further objects and advantages of the invention reside in the combination of elements and in thestructure as hereinafter described and as illustrated inthe accompanying drawings, in which y Fig. l is a central, longitudinal vertical section of the forward portion of a locomotive tender and the rearward portion of a locomotive with the invention applied thereto, partsbeing shown in elevation;

Fig. 2 is a sectionon the line 2-2 of Fig. l with parts removed;

Fig. 3 is a detail section on the line 3 3 of Fig 2;

- Fig. 4 is a section on the line 4-4 of Fig. 3 with portions of the tender shown in section;

Fig. 5 is a detail of a portion of the endless conveyor with parts broken away; and

Fig. 6 is a longitudinal vertical section through a'portion of the tender illustrating a modified form of driving arrangement.

In the drawings, referring more particularly to the preferred form illustrated in Figures 1 to 5 inclusive, a locomotive is indicated generally by the numeral IB and the tender therefor is shown at Il. The locomotive comprises the conventional cab deck i2, nrebox i3 having a backwall I4 with an opening l5 therethrough, and the grates I6. The tender comprises the fuel bin l1 and the water compartment I8 separated by the rear slope sheet I9, side slope sheets 2!! and 2| and the bin bottom wall 22.

Extending longitudinally'of the fuel bin l 'l and mounted on the bin bottom wall 22 is a longitudinal endless feed conveyor 23 forming a movable floor for the fuel bin l1. This endless conveyor embodies a plurality of transverse L-shaped members 24 and welded in the opposite ends of the L-shaped members 24 are the lugs 25. The lugs 25 are tapped and threaded to receive the (Cl. 10S-232) threaded portion 2G of the bolts 2l. A plurality of links 28 forming a chain 29 engage the unthreaded portion 30 of the bolts 21 tying the L-shapedmembers 24 together. Y

The endless conveyor 23 travelsk about the 5 toothed wheels 3l, the links 28 tting between the teeth 32 of the wheels 3|.V The wheels 3l are secured to the transverse shaft 3,3 by means of Vthe keys 35, the shaft 33 being journaled in bearings as 36 which are fixed to thetender inner 10 walls 3l. At its rearward end the endless conveyor 23 is supported from the transverse shaft '34.

At the forward end of the tender and opening through its front wall is formed a compartment 38. arranged'to receive part or all ofthe driving 15 mechanism for the endless conveyor 23. The compartment 38 is located at one side of the end'- less conveyor 23, the upper portion thereof extending into one of the bunkers 39 and the lower portion extending into the water compartment I8. 20

An extension 40 of the shaft 33 penetrates into the compartment 38 and has a sprocket 4l mounted thereon. A smaller sprocket 42 its ratio to the larger sprocket 4I being such as toproduce the desired speed reduction, is mounted on a trans- 25 versely extending shaft 43 journaled in bearings 4d xed tothe sides of the compartment 38 vand is connected with the sprocket 4I byk a driving chain 45.

A longitudinal shaft 46 is mounted in the com- 30 partment 38, extending forwardly through its open forward end, and mounted on its rearward end is a bevel gear 4l engaging the bevel gear 48 mounted on thev shaft 43. A motor 49 for driving the endless conveyor 23 is preferably mounted 35 from the underside of the locomotive cab deck l2 and its power shaft 50 is universally connected with the shaft 46 through the extensible shaft 5S. In orderV to'prevent saggingfof the upper turn of the endless conveyor 23'and to prevent fuel 40 particles from lodging between the upper and lower turns, a plate 52 is provided directly beneath the upper turn and is securely attached to the tender inner walls 3l. Supported from ythe plate v52 are the bearings 53 and 54 for the shafts 45 33 and 34 respectively.

The bin bottom wall 22 is provided with a wear plate 55 extending laterally from one to the other of the tender inner walls V3l. The rearward end of the plate 55 curves upwardly following the 50 periphery of the endless conveyor and is attached to the rear slope sheet I9 forming a seal for preventing fuel from lodging behind the endless conveyor. The forward end of the plate 55 v curves upwardly following the periphery of the 55 endless conveyor, then slopes downwardly and forwardly and extends horizontally forward forming a shovelling platform 56 upon which the fuel is delivered by the endless conveyor. The sloping rearwall of the shovelling platform 55 permits greater ease in filling the shovel with coal and prevents the coal from being pushed back in contact with the endless conveyor.

A coalgate 57 is arranged between the bunkers 39 immediately in front of the endless conveyor 23. A space 58 is permitted to remain between the bottom of the coalgate 51 andthe endless conveyor 23, through which coal I'alls onto the shovelling platform 55. When the bin is full, coal will of itself fall by Vgravityy through the space 53, and when the supply of coal decreases to such an extent that it no longer falls through the space 58 by gravity then-the endless corrveyor 23 is put in operation to deliverthe coal through the space 58.

In Figure 6 is shown a modiedform of driving arrangement'. The motor M is shown mounted inthe compartment 38, arranged to reciprocate the piston rod B in the piston rod guide 6l. AV lever S2 having arms 63 and 64 is pivotally mounted on the shaft 43. The arm 63 is provided with a slot S5' receiving the pin 66 of the piston rod 6B. The arm 64 is providedlwith a toothed members? arrangedto engage the serrated wheel 68 which is rigidly fixed to the 'shaft 43. Thus when the pistona is movedtowards thev right, the toothed member il engages the serrated edge ofthe wheel 68 moving it in a counter clockwise direction. The movement of the wheel '5S is communicated to the 'shaft 43 in turn moving the driving' chainV 45 which drives the endless conveyor 23thiough the shaft 4B. When the piston 80 isi moved towards" the left, the toothed member' '61 is moved in a clockwise direction disengaging it from the serrated wheel 68 permitting it to ride over the serrations to a position where it may again be moved in a counter clockwise direction'movingthe serrated wheel e8 on the return stroke of the piston rod '60.

The preferred form of the invention is farranged to be operated continuouslyanduninter* ruptedly while the modified form `operates continuously but interruptedly `since motion in the latter form is transmitted to the endless conveyor on only one rstroke of the piston rod 6D. The endless conveyor of either the preferred or the modified form of the invention is however, operated only at such intervals whenthe coal no longer of itself falls through the opening between the front of the endless conveyor and the coal gate and when it is desired to add coal to the re in the locomotive iirebox.
