The shaft 36 has secured thereto a sprocket 52 which is also engaged by the endless chain 4|. Motion is transmitted to the chain 1 4| by a drive unit 53 which includes a casing 54 secured to a side Wall of the housing member 33. The casing contains a pair of shafts 56, 51 connected by the gear 58 and pinion 59, respectively. 'Power, supplied to the shaft 51 from any suitable source by means of a joint 66 (Fig. 2) is transmitted through gearing 58,59 to the shaft 56 which has secured on an exterior end thereof a sprocket gear 6| engaging the chain 4|.
The forward end of the shaft 36 carries a detachable coupling 62 which is connected in well known manner to a coupling 63, forming a universal joint 64 disposed within the hollow shell 50. On the rearward lower end of the rear conduit section 28 is a semi-spherical flange 28a fitted against the under side of spherical surface 5|. In vertical transverse cross section, the
-- rearward portionof the conduit section 28 is forms with the conduit section 28 a cylindrical portion 69 therein. In this cylindrical portion 69 is mounted a disc 10, the outer surface of which is arcuateto permit angular movementof the disc. The rearward portion of the disc 10 detachably carries the. joint coupling 63 and on its 1 opposite side isfarranged to receive a disc 1| formed integrally with the conveyor screw 32.
' In the operation of this device, fuel in thebin I6 falls through an aperture 13 of the tender floor l'linto the trough conduit 2|. The conveyor screw 3| urges the fuel forwardly past the crusher 14,
I a portion 15 of which may be secured to the floor At'its rearward end, the. conveyor screw 3| and the screw 32, thereby securing a more direct rotation.
is provided with a journal 16 received'in a bearing 11 of a construction which restrains relative fore or aft movement of the screw incident to its Upon beingcrushed, the fuel passes into the forward portion 23 of the trough conduit. In order. to permit unobstructed passage of fuel through the sleeve 31, that portion of the conveyor screw 3| therein is provided with a hub 18 of reduced diameter. From the cylindrical sleeve 31, the fuel enters the spout 46 and discharges into thelowerend of the intermediate conduit 26 for conveyance to the locomotive by the conveyor screw 32.
Those familiar with the art willrecognize that the particular drive arrangement for the conveyor screws 3|, 32 permits'endwise delivery. of fuel by the conveyor screw 3| through the spout 46 and onto the conveyor screw 32. It will also be apparent that the construction permits forward inclination of the intermediate conduit 26 conveyance of fuel with fewer parts. Since the disc 16 has an arcuate outer periphery, the conveyor screw 32 is thus provided with a suitable hearing which allows for slight angular movement of the screw 32; at the same time, the disc 10 excludesfuel from working around the universal joint 64.
