INVENTOR Nazi/2 an M Lou/en ATTORN EY 'March 3, 1936. N. M. LOWER STOKER CONVEYER Fi led Oct. 10, 1934 Patented Mar. 3, 1936 UNITED STATES STOKER, CONVEYER Nathan M. Lower, Tuckahoe, N. Y., assignor to The Standard Stoker Company, Incorporated, a corporation of Delaware Application October 10, 1934, Serial No. 747,663

3 Claims.

This invention relates to stokers for locomotives and has for its object the provision of a stoker conveyer including a conduit section on the locomotive, a conduit section on the tender 5 and a non-extensible and -cntractible intermediate conduit at one end universally connected to the conduit section on the locomotive and at the other universally and slidably engaging the adjacent end of the conduit section on the tender.

The advantages of the invention will be apparent from the following description and the accompanying drawing, in which,

Fig. l is a central longitudinal section through a portion of a locomotive and tender with the 15 stoker conveyer of the invention applied thereto;

Fig. 2 is a cross section on the line 2-2 of Fig. 1; and

Fig. 3 is a cross section on the line 33 of Fig. 1.

On the drawing, the locomotive is indicated at I0, having a firebox ll provided with a firing opening I2 in the backhead l3 thereof. The tender l4 rearward of the locomotive has the usual fuel bin I5 with an apertured floor l6 spaced a distance above the underframe I! sufficient to provide space for a stoker conveyer as will presently appear. Any well known coupling connection 18 ties the tender to the locomotive and permits articulation between them.

Fuel is conveyed from the fuel bin l5 tothe firebox H by the stoker S, only that portion of which is shown necessary to illustrate the improved conveyer organization of this invention. The stoker includes a conduit system comprising the rearward trough section A held rigid to the apertured floor l6 by tie straps l9, a forward or riser conduit section B fixedly mounted by means such as the support 20 to the backhead l3 in communication with the firing opening l2, and a nonextensible and -contractible intermediate conduit section C extending between the rearward and forward conduit sections A and B.

Articulation between the conduit sections necessary because of the articulation between the locomotive and its tender is provided in the construction of and the relation between the intermediate section C and the adjacent ends of the trough and riser sections A and B. For this purpose a spherical ball 2| formed at the forward end of the intermediate section C is received in the spherical seat 22 facing outwardly from the lower end portion of the riser section B. This seat and the ball together with the complementary clamp member 23 form a universal joint connection tying the intermediate conduit section to the riser conduit section, preventing longitudinal movement of the one without the other.

The opposite end of the intermediate conduit section is formed with an enlarged sleeve or cylindrical portion 24 slidably fitting over the hollow spherical ball 25 of the trough section A. This construction permits universal as well as longitudinal movements between the trough and intermediate sections. Hence the universal connection between the intermediate and riser conduit sections and the universal and longitudinally slidable relation between the intermediate and trough sections permit the required articulation.

Fuel is conveyed through the conduit sections to the distributor 26 for distribution over the firebox by the universally connected screws 21 and 28 rotatably mounted in the trough and intermediate conduit sections respectively and by the separated screw section 29 mounted in the riser conduit section B. Any suitable drive mechanism may be employed to drive the screw section 29 through the gearing 30 at the base thereof and to drive the screw sections 21 and 28 through the shaft 3| leading to gearing (not shown) in the housing 32.

Not only is the intermediate conduit section 01' simple compact construction providing for the required articulation between the conveyer sections but it also simplifies uncoupling the locomotive and tender because there is no necessity for removing covers or other fastening members to permit the conveyer to pull apart.

I claim:

1. In an intercoupled locomotive and tender, a conveying system leading from the tender to the locomotive comprising a conduit section mounted on the tender and having an unvarying longitudinal relation therewith, a conveyer screw in said conduit, a conduit section mounted on the locomotive and having an unvarying longitudinal re lation therewith, a conveyer screw in said conduit, an intermediate conduit of unvarying length between the first and second named conduits arranged with its axis. approximately in the horizontal plane of the axis of said first named conduit section, said intermediate conduit at one end being flexibly related with one of said conduit sections and having an unvarying longitudinal relation therewith, said intermediate conduit at its opposite end being flexibly related with the other of said conduit sections and having a varying longitudinal relation therewith, and a conveyer screw in said intermediate conduit, said last named conveyer screw at one end being flexibly connected to one of said named conveyer screws and having an unvarying longitudinal relation therewith, said last named conveyer screw at its opposite end being offset and separated from the adjacent end of the other of said conveyer screws and having a varying longitudinal relation therewith.

2. In an intercoupled locomotive and tender, a conveying system leading fromthe tender to the locomotive comprising a conduit section mounted on the tender and having an unvarying longitudinal relation therewith, a conveyer screw in said conduit, a conduit section mounted on the locomotive and having an unvarying longitudinal relation therewith, a conveyer screw in said conduit, an intermediate conduit of unvarying length between the first and second named conduits ar ranged with its axis approximately in the horizontal plane of the axis of said first named conduit section, said intermediate conduit at one end being flexibly related with one of said conduit sections and having an unvarying longitudinal relation therewith, said intermediate conduit at its opposite end being flexibly related with the other of said conduit sections and having a varying longitudinal relation therewith, and a conveyer screw in said intermediate conduit, said last nam'ed conveyer screw at one end being flexibly connected to said first named conveyer screw and having an unvarying longitudinal relation therewith, said last named conveyer screw at its opposite end being ofiset and separated from the second named conveyer screw and having a varying longitudinal relation therewith.

3. In an intercoupled locomotive and tender, a conveying system leading from the tender to the locomotive comprising a conduit section mounted on the tender and having an unvarying longitudinal relation therewith, a conveyer screw in said conduit, a conduit section mounted on the locomotive and having an unvarying longitudinal relation therewith, a conveyer screw in said conduit, an intermediate conduit of unvarying length between the first and second named conduits, said intermediate conduit at one end being flexibly related with one of said conduit sections and. having an unvarying longitudinal'relation therewith, said intermediate conduit at its opposite end being flexibly related with the other of said conduit sections and having a varying longitudinal relation therewith, and a conveyer screw in said intermediate conduit, said last named conveyer screw at one end being flexibly connected to one of said named conveyer screws and having an unvarying longitudinal relation therewith, said last named conveyer screw at its opposite end being offset and separated from the adjacent end of the other of said conveyer screws and having a varying longitudinal relation therewith.
