SPECIFICATION forming part of Letters latent No. 764,332, dated July 5, 1904.

Application filed April 8, 1904. Serial No. 202,194. (No model.)

To @LZ w/zolrt t may con/cern:

Be it known that I, RALPH BAGGALEY, oil` Pittsburg, in the countyot' Allegheny and State of Pennsylvania, have invented a new and useful Converter,oiI which the following is a specification, reference being had to the accompanying drawings, in which- Figure lis a vertical longitudinal section of the converter. Fig. 2 is a vertical cross-section on the line Il II of Fig. l. Fig. 3 is a detail view on a larger scale.

.My invention provides means by'which a Bessemer converter used for treating copper matte can be cooled with air and the extent of the cooling and the place of its application regulated as desired.

ln the drawings, 2 represents the exterior metal shell of a converter, having an interior brick lining 3, back of which is the air-cooling device which forms the subject of the present invention. A series of horizontal pipes 4 extend from end to end of the converter within the shell, and these pipes, oli' which l show three, are open at the ends, and they supply the air for the cooling-channels, which extend transversely around the sides et the converter.` For that reason they should be made as large as convenient. They are covered with blocks 4, of brick, tile, or metal, having a series of lateral holes 5 5, communieating with holes in the pipes 4, adapted to receive the ends of other metal pipes, 6, which 4 extend upward along the sides of the converter and terminate at short tubes 7, open at the end outside the shell and having lateral holes bb, which register with the pipes. 1n like manner at the ends of the converter are blocks il, extending through the converter-shell intoV the lining and having lateral holes, into which are fitted pipes 6', which` extend up te tubes 7. The pipes 6 6 are embedded in hollow bricks, tiles, or metal blocks 8 8, which are strung upon the pipes and are thus built into a compact structure on the interior of the metal shell, and within this structure is the lining 3, preferably of magnesite brick. The invention thus affords within the metal converter-shell a large number of vertical airpassages communicating at the bottom with the external air through the horizontal passages 4 4, and at the top through the tu bes 7,

so that there will be a natural circulation of air, which will cool the pipes and thus cool the converter-lining, to which the pipes present a large area 0i contact. It it is desired to localize the cooling action, the tubes 7 7 at the places not needed to be cooled may be closed with' screw caps or plugs 9, which will at once stop the circulation of air therethrough, or the circulation may be established in all the pipes or closed in all ot' them. In like manner it may be found that a circulating air current through the outer pipes may be suilicient to accomplish the result, and this can be effected by capping the two inner pipes 4 4 at each. end of the converter, which will have have the eiiect oi preventing any air-circulation through the entire series of pipes connected therewith. The hotter the convertershell and lining become the more rapid will be the air-circulation and the more eilicient the cooling action. This is accomplished automatically and without the expense and inconvenience of using water or `forced air. The degree of the cooling action over the entire area can be regulated at will and without expense by the three complete systems ot' pipes, and the cooling may be localized at any portion of the shell or heads, as described above.

"he converter' may be provided with burn ers B, supplying flame from the jets of oil or gas above the bath.

The employment of the upright metal pipes on which the hollow bricks are strung is im portant, because if they were not employed the air-passages would become clogged in use or in the operation oi laying the blocks with mortar, clay, or cement. This will not occur with the metal pipes.

Within the scope of my invention as de- {ined in the claims the parts may be modified, since What I claim is.

1. A converter having ventilated passages open to the air at the bottom, and other passages leading therefrom upward along the shell; substantially as described.

2. A converter having a series of ventilating air-passages open to the atmosphere above and below, the inlet being lower .than the outlet; substantially as described.

3. A converter having ventilated passages IOO IO stantially as described.

5. A converter having' ventilated passages open to the air at the bottom, and other pas# sages leading therefrom along the shell, said converter having a burner for supplying auX- iliary heat within the same; substantially as I5 described.

In testimony whereof I have hereunto set my hand.
