Application filed January 12,1912; Serial No. 670,836.

lump fuel is fed in through the distributers.

' by means of a jet or blast of steam or other October 2, 1911. One of the objects of this present inven-- fluid under pressure as set forth in our prior application Ser. No. 652,462, filed tion is to provide an improved form of distributer having a wide shield-like extension at the top beyond the open end and having deflecting ribs or surfaces for distributing the fuel throughout the length of the firebox. 25

This form is especially desired for use at the sides of the furnace.

Another object is toprevent to a large'extent, the warping of the distributers due distributers. I

In the accompanying drawings: Figure 1 is a plan of one form of-our improved,d1s-- tributing device; Fig. 2, a longitudinal section of same; Fig. 3, a plan with a portion in horizontal section, showing a slight modification; Fig. 4, a longitudinal section of the same, a portion of the elbow being 'shown in elevation; Fig. 5, an inside ,end View; Fig. 6, anoutside end view of, the distributor shown in Figs. 3 and 4; and Fig. 7, minside end view of the distributer shown in Figs. 1 and 2.

According to the. construction shown in- -the drawings, the improvement is illustrated as applied in connection with that type of distributer having a cylindrical body, 19, adapted to be-inserted from within the furnace through the opening, 21, in the furnace 50.

. ably connected to the elbow, 19*, on the out wall, or water leg of the the box, and detachside of the boiler, the elbow having connections for fuel supply, an air inlet-opening,

shield 23.

forth and claimed in our co-pendingapplication, Serf No. 670,835 filed of even-date herewith. r

I 27 and a fluid pressure blast, 28, all as set v When used as side distributers, as in the.

present instance, it is desired that the 'fuel should be evenly distributed through the length of the fire box and to thefar'corners, and for this purpose the inner end of the distribute!" may be formed, at the top with a broad flaring hood .or shield-like en. tension, 23, projecting beyond the fuel dis:

24, "for diverting the fuel upward at this point against. the under surface. of the has Y chargeopening, 22, and as shown, .thennder' As shown inv Figs. 3, 4, and 5, the-lateral. I

extension ofthe shield is principally at one s1de of the center line of the distributer, and 1n this case a deflecting-rib, .26, is"10-' cated on the underside of the shield for dlvertmg a portion of the fuel toward the middle portion of thefurnacegra'te.

For the purpose of preventing the warping of the broad extension shield or hood,

23, dueto the high temperature to which it is exposed in the furnace, thelongitudinally diverging ribs, 29, are provided. on the .to'p oftheshield. Asthe sidedistributers are usually de signed to receive their fuel supply through inclined pipes, the elbow I portion, '19; is preferably turned at an angle to the vertical, as shown more particularly in Fig. 6. As the fuel is-driven'through the distrihuter by the steam: blast, it is deflected up ward by the wedge projection 24 at the discharge opening and impinges againstthe under side of the shield, 23, from which it is spreadout laterally and distributed over a wide range of grate area throughout the length of. the fire box,

: we claim as new, and desire to' secure .by Letters Patent, is z. In amechanical stoker, the; combination wlth a furnace Wall having an opening, of a bottom of the discharge end of said tubular fuel distributed comprising an elbow out-. shank. side the wall and provided with fuel and In testimony whereof We have hereunto fluid pressure connlectiogs, E1, fiat flarinig disset our hands.
