4 Claims.

This invention relates to a stoker for a boiler firebox and primarily has for its object the provision of a novel and improved form of construction whereby the application of the stoker to the firebox is simplified and rendered more convenient.

There are in commercial use, fireboxes of many diiferent types for stationary boilers as well as for locomotive boilers, and the firebox walls may slope at various angles with respect to the horizontal. In applying to a firebox, a stoker of the type in which the forward end is attached to the firebox wall, it is apparent that difficulty is encountered in providing a stoker which is adapted for attachment to firebox walls of different slopes. Many stokers in use today have a flange formed integral with the forward end of the stoker conduit, and the conduit is fastened to the firebox wall by bolting the flange to the firebox Wall. However, in such instances, it is obvious that the forward end of each stoker must be particularly designed in accordance with the slope of the firebox wall of each particular installation. Therefore, instead of one stock forward conduit, it would be necessary to design a forward conduit to meet the particular conditions of each firebox for which an installation is to be made.

In the application of stokers to a firebox in which the forward conduit is not provided with an integrally formed fiange but a separate bracket is provided, it is necessary todrill holes in the proper places in the stoker conduit walls before the stoker can be assembled in place.

It is therefore a further object of my invention to provide a stoker that can be installed on a firebox irrespective of the slope of the firebox wall and eliminate the necessity of performing further operations on the stoker forward end other than merely attaching it to the firebox wall.

In stokers of the type wherein the blast chambers and distributing table are attached to the delivery end of the conduit it may be found necessary to change the slope of the conduit slightly to maintain the distributing table in a horizontal position or for some other reason it may be found necessary to slightly change the slope of the conduit. It is therefore, a further object of this invention to provide means, for securing the forward end of the conduit rigidly with the firebox wall, that is adjustable to compensate for such changes in the slope of the conduit, eliminating the necessity of performing any mechanical operations on that portion of the stoker adjacent the firebox wall.

Therefore, my present invention addressed to the efficient elimination of the ills above enumerated, further resides in the novel details of construction, combination and arrangement of parts which will be pointed out in the appended claims, reference being had to the accompanying drawing, in which:

Figure 1 is a side view partly in elevation and partly in section of the stoker and associated parts of the boiler firebox.

Figure 2 is a plan View of the construction illustrated in Figure 1.

Figure 3 is an elevational view of the stoker as viewed from the left-hand side of Figure 1.

Referring more particularly to the drawing, 4 indicates the back wall of a boiler firebox which may be of any desired construction, and 5 indicates the firing opening in the back wall. Disposed Within the firing opening is a blast chamber 6, and extending forwardly from the blast chamber is a distributing table l. A ledge ta integral with the blast chamber and underlying the distributing table supports the latter and is provided with the opening 5h closely receiving the downwardly projecting lug lot of the table for removably securing the table to the blast chamber. Associated with the blast chamber is a fuel conduit 8, of any desired construction for delivering fuel to the distributing table I. Disposed between the sides of the conduit and the backhead are angular brackets 9. The angular brackets may be secured to the backhead by means such as studs l9, and nuts I i. The brackets extend rearwardly from the backhead at substantially right angles alongside the side Walls of the conduit 8, and are secured to the conduit by means such as studs 01 bolts l2, and nuts 53. Rearwarol of studs l2 are studs i i, arranged for movement in slots 15. Slots iii are constructed as segments of a circle and have for their axis studs l2. It will be observed that the conduit 8 is capable of pivotal adjustment about the studs 2 with respect to the firebox backwall and between the brackets 9.

From the foregoing it is seen that the conduit 8 may be pivotally adjusted to any angle necessary to position the distributing table I, on a substantially horizontal line, since the distributing table is movable with the conduit.

After the conduit 8 is adjusted to the proper angle, nuts 53 and H are then tightened, thus resulting in the conduit being attached rigidly to the backhead. Bracket ii is also applied for additional support to the conduit at its lower portion. The length of the bracket I! may be conveniently changed to fit between the conduit and backhead by bending it.

Thus having fully explained the invention, I claim:

1. In a stoking mechanism for locomotives in combination, a locomotive having an apertured boiler backhead, a fuel conduit delivering to the aperture, a blast chamber rigidly attached to said conduit, a removable distributing table secured to and extending forwardly from said blast chamber and in position to receive fuel from said conduit, means for securely attaching said conduit to said backhead, said means permitting pivotal adjustment of said conduit about a horizontal transverse axis thereby providing means for adjusting said distributing table to a substantially horizontal position.

2. In a stoking mechanism for locomotives in combination, a locomotive having an apertured boiler backhead, a fuel conduit delivering to the aperture, a blast chamber rigidly attached to said conduit, a removable distributing table extending forwardly from said blast chamber, said table being secured in fixed relation with said conduit and blast chamber and in position to receive fuel from said conduit, means for securely attaching said conduit to said backhead, said means permitting pivotal adjustment of said conduit about a horizontal transverse axis, thereby providing means for adjusting said distributing table to a substantially horizontal position, and means for securing said conduit rigidly to said backhead after adjustment thereof.

3. In combination, a boiler firebox provided with a firing opening in a wall thereof, an upwardly extending fuel conduit positioned outside the firebox and at its delivery end communicating with said firing opening, fuel distributing apparatus disposed in said opening and being rigidly secured to said conduit, means for attaching said conduit to said backhead, said means permitting pivotal adjustment of said conduit about a transverse axis thereby providing means for adjusting said fuel distributing apparatus in any one of a number of positions.

4. In combination, a boiler firebox having a 15 firing opening therein, a fuel conduit outside the firebox in communication with said firing opening, a bracket at each side of the conduit adjacent its delivery end rigidly secured to said firebox, means pivotally mounting said conduit at its delivery end in said brackets for movement only about a horizontal axis extending transversely of the conduit, and means rigidly securing the conduit to the brackets in any one of a number of positions permitted by said pivotal mounting.
