4. Claims. 01. 110 101) This invention relates to Stoker mechanism, and more particularly to a distributor member therefor. p

The principal object of the invention is the i 5 provision of a new and improved stoker mechanism having means for directing portions of the fuel laterally into the rear corners ofthe fire-box.

Another object of the invention is the provision of a novel distributor plateprovided with new and improved means for connecting the plate to the locomotive and to the riser conduit.

A further object of the invention is the provision of a new and improved distributor plate having a nozzle rigidly connected thereto. 15

provision of a new and improved distributor plate that is cheap to manufacture, easily assembled in position in the stoker mechanism, that is eflicient in distributing the fuel over the grates of the ine-box, and that extends into the fire-box of the locomotive a minimum amount.

One embodiment of the invention is shown on the drawing, in which Fig. 1 is a longitudinal section of a portion of a locomotive showing the invention in position thereon;

Fig. 2 is a plan view of the plate; and Fig. 3 is a section on line 3-3 of Fig. 1. Referring now to the drawing, the reference character 10 designates a locomotive having a backhead 11 provided with a firing opening 12 therein. A fuel conduit is shown at 13 for conducting fuel froma source of supply to the firing opening 12. A distributor plate 14 extends forwardly from the conduit into the firebox 15 of the locomotive. The distributor plate is provided with a suitable support 16 resting on the lower marginal surface 17 of the opening 12. The distributor plate is secured in position in any suitable manner. Preferably the conduit 13 is provided with a forwardly extending lug 18 which is adapted to overlie a corresponding lug l9 rigidly secured to the backhead of the locomotive.

, The lugs 18 and 19 are provided with alined openings 21 for receiving a sleeve 22 which pivotally connects the two lugs together. The rear end of the distributor member is provided with a fuel nozzle 23 which is preferably though not necessarily made integral therewith and the nozzle is provided with a threaded opening in the passage 24 in the nozzle.

A steam pipe 25, extending upwardly through the sleeve member 22, is adapted to engage the threaded opening in the nozzle for holding the plate in position. The parts are so constructed A son further'object of the invention is the that the conduit 13 will have a pivotal movement relative to the plate 14.

' Thedistributor plate 14 has a plane flat upper surface, and is provided with a pair of low upstanding outwardly curved ribs 26 and 2'7. These ribsextend forwardly and laterally in opposite directions, and terminate adjacent the side edges of the plate. These ribs are preferably integral with the plate, and their inner ends merge with thesurface of the plate. The ribs are spaced apart to provide a free unobstructed wall for the free passage of fuel between them.

The ribs gradually increase in height toward their outer ends, which terminate adjacent to but spaced forward from the inner surface of the back wall of the fire-box, whereby they will check the velocity of portions of the fuel projected forwardly by steam from the nozzle 24 and will doflect other portions of the fuel laterally into the rear corners of the fire-box.

In the operation of the device fuel is fed forwardly onto the plate from the conduit 13, in front of the nozzle 24. The fuel is moved through the conduit by the screw 28 the forward end portion of which extends over and is tapered to conform to the slightly upturned forward end portion 29 of the bottom wall of the conduit. Portions of the fuel are projected forwardly across the unobstructed portion of the plate to the front of the fire-box, portions of it will strike the low ribs and, having its velocity checked, will be distributed over an intermediate portion of the grates, and other portions will be deflected by the ribs to the rear corners of the fire-box.

This is a division of my application Serial No. 105,164, filed April 28, 1926, upon which Patent 1,711,466 was granted April 30, 1929.

It is thought from the foregoing taken in connection with the accompanying drawing, that the construction and operation, of my device will be apparent to those skilled in the art, and that vari-' ous changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims.

I claim as my invention:

1. A distributor plate arranged to permit fuel to pass thereover for distribution comprising a body portion having a fiat upper surface, a single pair of ribs extending above said surface and curved forwardly and laterally, said ribs having their inner ends spaced apart and merging in said plate and gradually increasing in height toward their outer ends and terminating adjacent to the side edges of said plate, that portion of the top face of said plate included between said ribs declining from the remainder of said plate and having an unobstructed flat surface, the plane of the tops of said ribs and the plane of the upper surface of said plate sloping in opposite directions from the plane of the rearward portion of the upper surface of said plate and a pressure fluid nozzle integral with the rear end of said plate, said nozzle being positioned intermediate and rearward of the inner ends of said ribs.

2. A distributor plate arranged to permitfuel to pass thereover for distribution comprising a body portion having a flat upper surface, a single pair of ribs extending above said surface and curved forwardly and laterally, said ribs having their inner ends with respect to said plate spaced apart and merging in said plate and throughout gradually increasing in height toward their outer ends and terminating adjacent to the side edges of said plate, that portion of the top face of said plate included between said ribs having an unobstructed flat surface, the plane of the tops of said ribs and the plane of the forward portion of the upper surface of said plate sloping in opposite directions from the plane of the rearward portion of the upper surface of said plate.

3. In combination, a locomotive having a backhead with a firing opening therethrough, a distributor member extending forwardly into the firebox of said locomotive, said member being provided with an upper plane surface, said plane surface being interrupted by a single pair of low, upstanding, curved ribs extending only upwardly above the surface of said plate, the inner ends of said ribs with respect to said plate merging into the surface of said plate in spaced relation and gradually increasing in height to their outer ends, the outer ends of said ribs terminating adjacent to but spaced forwardly from the backwall of said locomotive, and a nozzle at the rear end of said plate in a vertical plane between said ribs for projecting fuel forwardly in an unobstructed path, said ribs being arranged to divert a portion of the fuel delivered to said plate laterally into the rear corners of the firebox and to impede the velocity of another portion of the fuel, the plane of the tops of said ribs and the plane of the upper surface of said plate sloping in opposite directions from the plane of the rearward portion of the upper surface of said plate.

4. In combination, a locomotive having a backhead provided with an opening therethrough, a distributor plate extending forwardly through said opening and means for supporting said plate on the lower margin of said opening, said plate being provided with a single pair of ribs rising above the upper surface thereof and curved forwardly and laterally and terminating at the sides of said plate, said ribs gradually increasing in height toward their forward ends and being spaced apart at their rear ends, that portion of the top face of said plate included between said ribs having an unobstructed flat surface, a distributor head at the rear of said plate arranged to project fuel thereover, said ribs being inclined at an angle from the surface of the plate to permit a portion of the fuel to pass thereover, to impede the velocity of another portion and to intercept and direct another portion to the corners of said backhead, the plane of the top of said ribs and the plane of the upper surface of said plate sloping in opposite directions from the plane of the rearward portion of the upper surface of said plate.
