SURDYKOWSKI, OF ERIE, PENNSYLVANIA, ASSIGNOB TO THE STANDARD STOIEB COMPANY, INCORPORATED, A CORPORATION OF DELAWARE LOCOKOTIVE FURNACE Application fled .Tune 6, 1929. Serial No. 868,751.
This invention relates to furnaces of locomotives which are provided with mechanical means, such as stokers for feeding fuel to the ecting the delivery of fuel upon and laterm ally across the rearward portion of the fire-.
a motive boiler havi box grates of the character above specified. A preferred embodiment of the inventlon is hereinafter described and is illustrated in the accompanying drawings, in which Fig. 1 is a vertical, longitudinal section through the firebox of a locomotive and ad'acent parts;
. ig. 2 is a detail vertical, longitudinal section of the means for. delivering the fuel into the firebox; and 1 Figs. 3 and 4 are views in perspective of parts of the fuel deliverin means.
The invention is ap lica le to any locomotive furnace provide with fuel advancing s grates and the furnace construction shown in the drawings is .merely illustrative of the aplication of the invention to furnaces of this type. v
At there is shown a portion of a locoa firebox 11 which is provided with a chambered backhead 12 in communication with the boiler 10. At 13, there is shown a chambered front wall for the firebox which it will be understood is also in communication with the chamber of the boiler. There is shown an arch 14 of masonr projecting backwardly and upwardly from t e wall 13 and supported on the tubes 15 which connect the chambers of the walls I 18, the arms of all of the bars of each set being connected together by means of a link as 19. Reciprocating actuating bars 20, 21 are associated respectively with the links as 19, and suitable mechanism, not shown, is provided for causing the reciprocation of these actuating bars, their movements being in opposite directions. The fuel bearing face of each of the grate bars normally extends forwardly from the line of the bar pivots and when the bar is rocked, it raises the fuel and deposits it upon thenext bar in advance. The grate is not in itself novel nor is its precise character important in connec tion with the present invention which simply requires that the grate be of such a character that it will shift the fuel from the end of the firebox at which it enters and which in locomotive practice is characterized as the rear end, to the opposite or front end.
Fuel advancing grates have been in coinmon use in hand fired furnaces, but no practical means has been known for using them in connection with existing types of mechanical stokers in railroad service, and consequently in this service, their use has been limited to the smaller locomotives, whose fuel capacity is within the limitation of hand firing.
- In the drawings, there are shown parts of one of the stokers now in common use in connection with locomotives, comprising a trans fer conveyor 22 for moving the fuel from the bin of the tender 23 to the locomotive and deliveringit to one or more riser conduits 24each of which delivers to a tube 25 setting through the backhead 12, a steam nozzle 26 being provided for blowing the fuel through the tube.
The tube 25 is of the general form shown in the patent to Lower No. 1,675,187, its bottom wall 27 being provided at its inner end with an extension carrying an abutment 28 for arresting the lower stratum of the fuel and causing its delivery through lateral chutes as 29 into the back corners of the firebox.
The tube as shown in the patent referred to was intended to provide for the scattering of the major part of the fuel over the entire grate area. For the.purpose of adapting it for use in connection with fuel advancing grates, its upper wall 30 is extended beyond the abutment 28 and at its inner end is provided with a depending skirt 31 which extends below the plane of the bottom wall of the tube. The inner face of the skirt 31 is approximately vertical and in width somewhat exceeding that of the body portion of the tube 25.
All of the coal which passes the abutment 28 is arrested by the skirt 31 and falls directly upon the rear portion of the grate. The inner face of the skirt 31 is so configured as to provide for a lateral spreading action. For this purpose, the inner face of the skirt is shown as transversely concave and the skirt or deflector cooperates with the abutment 28 and the chute 29 in order that fuel may be laid down upon the grate from sidewall to sidewall of the firebox.
Preferably the tube bottom 27 and the extension 30 of its top Wall are separate elements, detachably connected with the body of the tube to facilitate replacements.
In the operation of the device, the back corners of the grate are supplied with fuel by the action of the abutment 28. The remainder of the fuel is laid down across the rear end of the grate in a layer of approximately uniform depth. As the grates are rocked, this layer of fuel is thrown forwardly by the bar or bars upon which it rests, being received by the bars next in advance which in turn transfer it to adjacent bars. An even bed of fuel over the entire grate surface is thereby maintained, and much more reliably than with hand firing.
I claim as my invention:
1. In a locomotive furnace, in combination, a grate comprising rocking bars for. progressively advancing fuel, a fuel delivering nozzle projecting into the furnace, and delivering upon the rearward portion of the grate only, such nozzle comprising a tube and a skirt depending from the top of the tube and spaced from its open end, and mechanical means for delivering fuel to the nozzle.
2. In a locomotive furnace, in combination, a grate comprising rocking bars for progressively advancing fuel, a fuel delivering nozzle projecting into the furnace, and deliveriug upon the rearward portion of the grate only, such nozzle comprising a tube and a skirt depending from the top of the tube and spaced from its open end, the inner face of the skirt being transversely concave through an are extending the full width thereof, and mechanical means for delivering fuel to the nozzle.
3. In a locomotive furnace, in combination, a grate comprising rocking bars for progressively advancing fuel, a fuel delivering nozzle projecting into the furnace, and deliver-
