Referring first to Fig. 1, the locomotive A in cludes a boiler IIJ provided with a hollow back Wall II at the rear of the ?ireboX I2. In the backwall II is the ñring opening I3 which is 50 above the level of the cab deck I4 and the grates I5. Coupled to the locomotive at C is a tender B having a fuel bin I6 above the apertured floor I1. 'I'he improved stoker for transferring fuel from the bin I6 to the ñrebox I2 is indicated 55 generally at S and it includes the transfer con n _conveyor screws ZI and 25, vthereby eliminating‘fany fuel degradation at this point. ` ` The universal jointn30 operatively con »'nects a `shaft-3l,¿driven by the gearing 22,_ with the journalled shaft 28 _fortransmitting power to 30 operate the conveyor screw`25. ` Ateits upperiforward endfthe` tubular portion L23 isa-provided with ¿spherical shell‘32'which'is received in acomplernentary seat` 33 of the riser 'member' 34.v Thenlatt‘er _is rigidly- supported from ` 'the boiler.` `backwall` I I >`by, abracketßä and is in 35 clined-‘forwardly ¿fromjthe' seat "33 _at agreater angle of inclinationv than the tubular portion 23 and greater than 45 degrees. Within the riser member 34 is a conveyor screw 36, at its rear 40 ward end universally jointed as at 31 to the con veyor screw 25, and terminating at its upper end adjacent the mouth 38 of the riser member. Fuel distributing means 39 disposed at the lir ing opening I3 serves to distribute over the grates 45 I5 the fuel discharged through the mouth 38 of the riser member 34. The tubular portion 23 is provided with a foot pad 40 having a spherical bottom which rests upon a spherical surface 4I of the bracket 42 supported on the locomotive frame 9, thereby forming an additional support for the transfer conveyor member intermediate the ends thereof. The support bracket may be better described as being saucer or dish shaped in which is seated 55 2,129,365 2 the bottom of the foot pad 40 much after the fashion of a cup resting in its saucer, whereby La contact is maintained between the adjacent sur faces of the pad and bracket. This forms an ad ditional support for the transfer conveyor mem ber during its free swinging movement on the lo comotive and tender, and also relieves the strain from the universal connection between the ad jacent ends of the tubular portion 23 andthe riser member 34. It will be apparent from the drawing that, since the spherical shell 33 is at a considerable elevation above the main portion of the transfer conveyor I8, said conveyor is,'in effect, suspended from the riser member 34. This imposes a strain upon the universal connection 32, 33 which is in turn transmitted to the backwall II by rea son of the fact that said backwall rigidly sup ports the conduit member 34. Therefore, it is clear that the provision of an additional support The following is claimed as new and useful: 1. In combination with an intercoupled loco motive and tender, the former having a boiler backwall and a frame, and the latter being pro vided with a fuel bin, a fuel transfer conveyor 2.1 leading forwardly from said tender to said loco motive comprising a trough portion underlying on the locomotive frame 9 effectively relieves this strain. ' ‘ Fig. 2 illustrates a modification wherein the tu bular portion 50 of the transfer conveyor mem ber I8 is inclined at the angle of inclination of r3 a: the riser member 5|, which is at an angle greater than 45 degrees, and in alignment therewith. Within the tubular portion 50 is an elevating screw 52,` the lower end of which is operatively connected to gearing 53 driven by a shaft 54 which leads forwardly from the gear drive'at the rear of the screw 2l. The gearing 53 is> housed in a casing 55 carried by the transfer conveyor member I3. At its upper end, the screw 52 ter minates within the riser member 5I at a point 33 belowkthe level of the distributing means 39. The advantage of this construction over that of Fig. 1 is that the screw 52 is inclined at a relatively steep angle, and of itself urges fuel through the riser member by the direct action of its flights. Since the tubular portion 50 Vis in alignment with the `riser member 5|, the spherical seat 5|a of the latter affords considerably less support for the ball member 60 of the 'tubular portion 50 than does the universal joint construction il lustrated in Fig. l. Furthermore, the conveyor said bin and a conduit portion rigid with said trough portion, the forward end of said conduit portion being disposed above the level of said O trough portion, means carried by said trough portion movably supporting said transfer con veyor on the tender, means carried by the boiler backwall arranged to flexibly support the for ward end of said conduit portion, said fuel trans* fer conveyor being provided with a depending foot member, and a support member carried sole ly by the frame of the locomotive, one of said members at its free end having a concave sur face and the other of said members at its free 9.0 end having a convex surface, one of said curved surfaces fitting into the other of said curved sur faces, the engagement of said curved surfaces arresting substantial fore and aft movement of said transfer conveyor with respect to said loco motive as relative fore and aft movement be~ tween the locomotive and tender occurs. 2. In combination with an intercoupled loco motive and tender, the former having a boiler backwall and a frame, and the latter being pro 30 vided with a fuel bin, a fuel transfer conveyor leading forwardly from said tender to said lo comotive comprising> a trough portion underlying said bin and a conduit portion rigid with said trough portion, the forward end of said conduit i portion being disposed above the level of said trough portion, means carried by said trough portion movably supporting said transfer con veyor on the tender, means carried by the boiler backwall arranged to flexibly support the for- „2.A O ward end of said -conduit portion, said 'fuel transfer conveyor being provided with a depend ing foot member, and a support member carried solely by the frame of the locomotive, said mem bers being disposed intermediate said first and second named means, one of said members at its free end having a concave surface and the other i8 also carries the additional gearing 53 for the " 0f said members at its free end having a convex screw 52, so it will be obvious that the use of the surface, one of said curved surfaces ñtting into additional supporting means, comprising the bracket 42 carried ,by the vlocomotive frame 9 and the pad 40 which is formed with tubular portion 50, is of special advantage in this modi ñcation in relieving the strains imposed by the conveyor I8, upon the> backwall Il. ~ This application is a division of my co-pending application Serial No. 32,339, filed July 20, 1935, for improvements in Locomotive stokers, pat ented Mar. 16, 1937, No. 2,027,304. the other of said curved surfaces, the engagement of said curved surfaces arresting substantial fore and aft movement of said transfer conveyor with respect to said locomotive as relative fore and aft movement between the locomotive and tender occurs. - CHARLES J.
