THOMAS A. BUGKLAND, OF ST. LOUIS, MISSOURI.
LOCOMOTIVE-FURNACE.
SPECIFICATION forming part of Letters Patent No. 242,108, dated May 31, 1881,
Application filed September 28, 1880. (No model.)
To all whom it may concern:
Be it known that I, THOMAS A. BUCKLAND, of St. Louis, Missouri, have made a new and useful Improvement in Locomotive-Furnaces, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making partof this specification, in which- Figure 1 is a side elevation of a locomotive having the improvement, portionsof the view being in section Fig. 2, a vertical section taken on the line a: w of Fig. 5; Fig. 3, avertical transverse section taken on the line as m. of Fig. 2, looking toward the forward end of the locomotive; Fig. 4, another section taken on the line :0 w of Fig. 2, but looking in the opposite direction to that of Fig. 3; Fig. 5, a horizontal section taken on the line 00 x of Fig. 2 Fig. 6, a detail, being a horizontal sec tion taken through the stack above the damper; Fig. 7, a detail, showing the end of one of the tubes used in supporting the diaphragm and the mode of fastening it in the shell of the firechamber; and Figs. 8 and 9, details, being sectional views of the diaphragm.
The same letters denote the same parts.
By means of the present invention a more effectual means is obtained for preventing the cold air in firingifrom passing into the fines. The gaseous products of combustion are more thoroughly consumed, and a better draft through the grate is secured.
It consists partly in the means used iufixing the diaphragm-supports in the fire-chamber walls, partly in the mode of introducing steam into the furnace, and partly in the system of tubes and damper used in conducting air and gas from the stack into the furnace.
Referring to the drawings, A represents a locomotive having the improvements in question.
B represents the furnace-chamber.
A diaphragm, 0, extends from above the doorway to inward and downward into the furnace nearly tothe forward end, I), thereof, and reaching transversely entirely across the furnace. The diaphragm is made of tiles 0 0 c. Perforations c c extend longitudinally entirely through the tiles; but as in use the extreme lower ends of the perforations are liable to be closed by reason of the tiles fusing at the inner ends, branches 0 c and c 0 lead fromthe main perforations 0 c and respectively to the upper and under surfaces of the diaphragm, as seen in Figs. 5, 8, 9. The diaphragm is supported by tubes D D, which at their ends connect with the water-space a a at the sides of the furnace, providing fora water circulation through the tubes, and thereby protecting them fromthe fire. The tubes are held in place, and the joints around the ends of the tubes are made tight, in the following manner The tubes are longer than the width of the furnace-chamber, and preferably so that the tube ends d d project slightly into the spaces a a. The perforations in the furnacewalls I) b to receive the tube ends are larger in diameter than the tube ends. Upon the tube ends sleeves or thimbles E E, tapering as indicated in Fig. 7, are arranged. After the tubes are inserted in thelfurnace-walls the encircling sleeves are wedged into the annular spaces around the tubes, as shown. The sleeves are preferably furnished with flanges e c, and, after the sleeves are driven into place, they are kept from working loose by fastening the flanges c e, by means of the screw-bolts e e, to the walls b b. At the same time the tubes can, by being elongated and contracted by heat and cold, move in the sleeves without becoming loose therein and causing leakage.
The outer air may be taken into the perforations c c in the diaphragm C; but in place of air, steam, by means of the pipes F F, may be conducted from the boiler a into the passages c c, and thence into the furnace-chamber, issuing at the extreme ends of the passages c c, or through theoutlets 0 c 0 0 The outer air is received from the front of the locomotive-leg into the tubes G G. It passes thence into spaces g g, which are formed by means of tiles H, that are arranged at the forward lower end of the furnace-chamber, substantially as shown in Figs. 2, 3, 5. The air passes from the spaces g 9, through passages h h in the tiles H E, into the furnace-chamber. Other tiles, I I, may be arranged at the sides of the furnace-chamber, and shaped to form spaces 1; i, and having perforations 'i i extending from the spaces 43 i into the furnace-chamber.
I J J represent pipes leading from the stack K and connecting with the spaces 1' i. The hot air and gas passing up the stack may, by means of the partition k and damper k, be partially intercepted and carried, through the pipes J J, spaces i i, and perforations i i, into the furnace-chamber. By means of the dam p' er-rod L this last'dcscribed current may be regulated.
The diaphragm C and tiling II I coact to form a throat for the fiirnace-chamber, through which all the gaseous products of combustion must pass. By reason of its location, and in consequence of the diaphragm and tiling (they being made of a substance such as fire-clay) being capable of becoming highly heated, the gases given off from the fuel are very thoroughly consumed and a very high degree ofheat is attained. The result is improved by means of the air or steam admitted through the diaphragm, by means of the air admitted through the tiles 11 H, and by means of the air or gas admitted through the tubes J J and tiles I I. No cold air, when the furnace-door is opened, can pass to the tines L. The draft upward through the grate M is improved, causing a more perfect combustion, and an ample supply of oxygen, highly heated, is obtained through the perforated tiling and delivered into the furnace immediately at the throat form ed by means of the diaphragm and tilingthe point where it can be applied to the best advantage.
The tubes J J may, if desired, connect with one or more of the tubes G Gr.
I claim- 1. The combination of the walls I) 1), tubes D D, and tapered sleeves E E, said tubes and sleeves being separate parts, substantially as described.
2. The combination of the walls I) 1;, tubes 1) D, and tapered sleeves E E, said sleeves having the flanges c c fastened to the walls by means of the bolts 0 e, and said tubes and sleeves being separate parts, substantially as described.
3. The combination of the boiler a", pipes F F, and the diaphragm 0, having the perforations 0 c, substantially as described.
4. The combination of the stack K, tubes J J, spaces i 1', perforated tiles I I, and chamber B, substantially as described.
