SPECIFICATION forming part of Letters Patent No. 605,206, dated June 7, 1898.
Application filed August 6, 1896. Serial No. 601,912. (No model.) Patented in England July 18, 1895, No. 13,371; in Germany August 20, 1895, No. 87,5 16; in France September 14,1895, No. 250,290,- in Belgium November 11, 1895, No. I 118,308; in Italy November 16, 1895,No. 10,171.; in Austria January 11, 1896, No. 46,108, and in CallatlaI'ebz-uary 14,
To all whom it may concern:
Be it known that 1, ANDREW PILLA'IT, of
- Nottingham, in the county of Nottingham,
No. 250,290, of September 14, 1895; Belgian,
No. 118,308, of November 11, 1895; Italian, No. 40,171, of November 16, 1895; Austrian, No. 46,108, of January 11, 1896, and Canadian, No. 57,337, of February 14, 1896.
My improvement consists in the combination, with the bridge-wall, of a furnace provided with an opening or openings, of a grate composed of bars having continuous passages from one end to the other, and openings along their lower portions, communicating with said continuous passages, the said continuous passages being in communication with the opening or openings of the bridgewall of the furnace.
In the accompanying drawings, Figure 1 is a vertical section of portions of a furnace embodying my improvement, the section being taken lengthwise of the grate-bars; Fig. 2 is a top View of grate-bars comprised in said furnace. Fig. 3 is a side View of such gratebars. Fig. 4 is a transverse section of one of the grate-bars.
Similar letters of reference design ate corresponding parts in all the figures.
A designates the chamber of a furnace embodying my improvement. I have not attempted to show this in detail, as it may be of any suitable construction comprising an ash-pit and a combustion-chamber, and additionally a bridge-Wall B, which may be of any suitable construction, but is to have an opening or openings b extending horizontally through it.
. O designates a grate composed of gratebars, here shown as made of longitudinal sections 0 c fitted together. The sections 0 are open from end to end and communicate with the opening or openings b of the bridgewall B between the ash-pit and combustionthe openings c chamber. The sections 0 are also open from endto end and communicate with the interior of the sections 0. As here shown, the sections 0 c are rabbeted, so as to malre a close joint 0 where they communicate. In the present example of my improvement I have shown the sections c as having enlarged end bearings adapted to the inner bearingfaces of the openings 12 and somewhat depressed inlet portions or months 0 The grate-bars are provided with a number of openings 0 and these I have shown in both the sections c 0 These openings are in the lower portion of the bars and preferably on opposite sides of the center line. They extend upwardly and communicate with the openings with which the grate-bars are provided longitudinally from end to end.
It will be seen thatby my invention air may enter the grate-bars at the end which is the farthest from the bridge-wall. In the present instance such air will enter from the ash-pit; but this is not essential to my improvement. Air will also enter the grate-bars through their openings 0 This air will of course be highly heated by radiation before entering A large body of highlyheated air is by my improvementcaused to flow continually through the grate-bars, thus keeping the bars sufficiently cool to preserve their integrity and supplying oxygen in a condition well fitted for combustion just beyond the bridge-wall, where it may combine with carbon, which will mainly be in the form of soot or smoke that has been carried over the bridge-wall with the products of combustion.
The heated air and carbon will enter into com- *rents of air are admitted thereto regularly throughout the lengths of the bars they will inevitably clog up, become inoperative, and burn out. I am also aware that bars have been made with longitudinal channels and with openings at intervals, but merely to prevent rapid burning out, and never with end bearings adapted to permit their use with perforated bridge-Walls and never arranged to supply heated air to combustion-chambers beyond the bridge-walls.
What I claim as my invention, and desire to secure by Letters Patent, is
1.- A grate-bar adapted to be fitted in a furnace with one end communicating with an vopening through the bridge-wall leading to the combustion-chamber, and having a longitudinal passage extending to said end and ANDREW PILLATT.
