,SPECIFICATION forming part of Letters Patent No. 519,218, `dated May 1` 1894. l

Divided and this application -tlled December 12, 1893. Serial Original application tiled April 18, 1893Serial citizen of the United States, residing at Butte city, Montana, have invented certain new and useful Improvements in Converters for Smelt` an application filed In thedrawingalFigure lis aside elevation of my improved converter; Fig. 2 a vertical `view ofthe bottom of the converter detached; and Fig. 4t a vertical section taken on line 4s of Fig. l.` f

In constructing my improved converter, I make a converter provided with a smelting or converting chamber, A, having side'water water jackets are made of sheets of metal with a space between them for the circulation of water. The edges, ct, of the inner sheets are turned or bent outward and fastened to the edges of the outer sheets byrivets, or in` any other convenient way. In this! way,I avoid` all seams, rivet holes, or other openings through the inner sheet of thewatervjack-` ets, so that all liability of leakage into the converter, which may occasion accidents, is avoided. The bottom water jacket is intended to fit in and to be inclosed by the lower ends of the side jackets, as shown in the drawings. The upper end of the converter,

into a dust chamber, and has proper communlcation or connection with a smoke stack, as

is now the usual construction. In order to support the converter in a versupports or standards, B, which are provided with journals or bearings, Z), at their upper ends. 1 i v t I provide the converter with `hollow trunnions, C, adapted to rest and be supportedin the journals of the supports or standards on which the converter is mounted. Through oneof the hollow trunnions I introduce a blast pipe, D, so that a blastor current of and througha continuation of the blast pipe,

`D', whichljcommunicates at its upper end .with the hollow'trunnin, and leads at' its lower end tofthetuyeres, d, which Apreferably enter the converter through the bottom water jacket more 'at one 'side of the bottom than' the other, asshown in Fig. 2. I carry a water pipe, E, leadingfrom a `proper source of supply through the other hollow "trunnion 'and` `down to or near the bottomofthe side water jacket, which pipe may be divided into branches, one leading into the side Water jacketand the other into the bottom water jacket, so as to supply the requisite quantity of waterto each. Pipes, E', leadfrom the water jackets out through the holloW trunnion, to permit the water to `iiow through the water jacket and be carried off, so that a fresh supply will constantly be introduced into the water j ackets."

I make a section of the converter, F,which will be above the surface of the molten mate rial when the converter is in its initial working4 position, 4of brick work or other frangible a tap to draw off from time to timethe desired quantity of molten material.

material, so that it can be punctured to form As willbe apparent from the description 1 up tothis point, the converter is intended to be tipped or turned over, las represented by dotted lines in Fig. 2, whenit is desired to draw off a quantity of molten material. The section, F, in whichthe tapis intended to be made, will be below the surface of the molten material when the converter is tipped over to draw off a portion ofthe charge. At such times also the tuyeres, d, which, as above stated, are arranged toward one side of the bottom of the converter, will open into the converter above the surface of the molten Inaterial, so that the blast will not be driven through no r agitato the material when, the converter is tipped to draw off the material. It will thus be permitted tosettle and assume the condition desired before drawing off.

In order to tip the converter, I arrange a gear wheel, G, on one of the trunnions, and a rack, G', with its teeth"intermeshing with the `gear wheel, and to move this rack up and down whenever it is desired to tip the couverter, I employ a hydraulic cylinder, II, the piston in which connects with the rack, so that when water is admitted behind the piston it will move the rack up, turn the gear Wheel, G, and tip the converter.

It will thus be seen that by changing the position of the converter with its converting chamber the molten material in it occupies one place while the converting chamber is in its initial or working position, and another place when it is in its discharging position. In a word, it changes its position relatively to the converting chamber to permit the discharge and prevent the blast of air from agitating the molten material.

I claim- 1. A tipping, tapping converter having a smelting chamber for the reception of molten materials, tnyeres for the admission of an air blast, a section of brick work arranged above any molten material in such chamber when in its initial working position and below the surface of any such material when the converter is tipped, and means for tipping the converter, substantially as described.

2. A tipping, tapping converter having water jackets entirely surrounding its smelting l chamber, hollow trunnions for supporting such converters, tnyeres for the admission of an air blast in the bottom of such converter, g blast pipe connecting such tnyeres and leading in through the hollow trunnion, water supply and discharge pipes connected with such Water chambers and leading inthrongh the trunnion, and asection of such converter Wall I formed of brick Work arranged at a point above any molten material in such chamber when the converter is in its initial working position and below such material when the converter is tipped, and means for tipping 4 the converter, substan tially as described.
