To a/ZZ whom it may concern:
Be it known that I, JAMES BALLANTYNE I-IANNAY, a citizen of England, residing at Cove Castle, Loch Long, in the county of Dumbarton, Scotland, have invented a new and useful Apparatus for the Manufacture of Sulphate-of-Lead Pigment, (for which I have obtained patent in Great Britain, dated J an-l uary 24, 1889, No. 1,282; Cape of Good Hope, dated December 20, 1889, No. 569; Norway, dated July 11, 1889, No. 1,413; Luxemburg, dated July 11,1889, No. 1,156; Queensland, dated August 16, 1889, No. 821; Italy, dated September 11, 1889, Vol. LI, No. 25; Victoria, dated June 21, 1889, No. 6,841; New South W'ales, dated-J une 24, 1889, No. 1,494; South Australia, dated June 25, 1889, No. 1,338; France, dated May 20, 1889, No. 198,335; Belgium, dated May 20,1889, No. 86,300; Canada, dated November 21, 1889, No. 32,891; Spain, dated August 30, 1889, No.'9,622, and India,
` dated February 21, 1890, No. 205,) of which the following is a specification.
My invention relates to an apparatus for treatment of galena or other suitable lead ore containing sulphur, so as to produce sulphate of lead in a pure state, available as a pigment. For this purpose I volatilize'the ore, along with additional sulphur, if necessary,in a furnace constructed and worked as a gas-producer. The ore is sprinkled over or through the coke with which the producer is fed, and the fumes, along with the produced gases, of which combustible carbonio oxide forms part, pass into a combustion-chamber to which air is admitted. In this chamber the combustible gases burn and the fumes are reheated, become oxidized, producing sulphate of lead. From the combustion-chamber the gases, along with the sulphate-of-lead fumes, pass up a vertical tower or flue (in which part of the sulphate is deposited) to a condenser, in which, by means of a steam-jet acting as an injector, the gases and fumes are caused to pass through water. In this water the principal part of the sulphate of lead is deposited. The mixture of sulphate and water is drained or pumped from the condenser-tank and washed with water, preferably several times, and is then dried and 5o ready for use. The fumes generally carry with them metallic oxides, which, if left in the sulphate of lead, would affect the purity of its white color. The oxides which usually accompany the fumes being soluble in dilute sulphuric acid, it is of advantage to acidulate the water of the condenser and also that of the firstwashing-tank with a little sulphuric acid, which dissolves the oxides present, so that they are Washed out. phate deposited in the flue and passages is from time to time removed and washed, first with acidulated water and then along with the product from the condenser. In some cases the gases and fumes carry with them 7 Figure 1 is a longitudinal section of the whole apparatus, and Fig. 2 is a transverse section of the furnace.
A is the volatilizing producer-furnace,
which is charged through the door a with 8o coke, having the galena or other lead ore sprinkled over or through it. Combustion is maintained in the producer either by an airblast directed through tuyeres a into the lower part of the furnace, orit may be by an indraft caused by an injector steam-jet, as in many gas-producers. The produced gases, which are partly combustible, pass along with the fumes from the ore through a narrow opening a2 into the combustion-cham- 9o The powdery sul- 6o This 7c y F. By the action of this jet the gases and fumes are caused to pass through several permeable screens f, immersed in the water or acidulated water of the condenser F and suspended by a support a around or about the lower portion of the tube forming the top opening m of the condenser. The gases escape by the tube or pipe t' at the top of the condenser, while the sulphate of lead subsides toward the funnel-shaped bottom of the condenser. From this the mixture of water and sulphate is pumped by a pump G, while water is supplied to the condenser F from a cistern f', fed by a ball-cock. From the pump Gr the mixture of water and sulphate is delivered to washing-tanks, where the material is washed in the usual way, and whence, aftersubsidence and decautation, the washed sulphate is removed to be dried.
At the bottom of the tower C is a door, by which access is given to remove the powdery sulphate deposited in the tower and in the chamber B, other doors being provided, if necessary, to give access to various parts of the chamber and ues.
Although the drawings, Fig. 1, show only one furnace A dischargingits gases and fumes into the combustion-chamber B, there may be several furnaces such asA communieating with the one chamber B, or with the fine b beyond it, these furnaces being worked either simultaneously or in rotation; also, instead of a single steam -injector jet E,
there may be several of these when the volume of fumes and gases is considerable.
Having thus described the nature of my invention and the best means I know of carrying the same into practical effect, I claiml. An apparatus for the manufacture of sulphate-of-lead pigment, consisting of a gasproducing furnace, a combustion-chamber having an air-supply and in which the combustible gases from the gas-producing f urn ace burn and the fumes are reheated by such combustion, and a condenser connected with said combustion-chamber, substantially as described.

An apparatus for the manufacture of sulphate-of-lead pigment, consisting of a gasproducing furnace for the lead ore, a combustion-chamber connected with the furnace and having tuyeres, vertical and horizontal tlues for conducting the gases and sulphate of-lead fumes, a condenser having a top inletopening connected to the horizontal flue, a top gas-discharge tube or pipe and suspended permeable screens arranged about the top inlet-opening, and a steam-injector jet at the rear end of the horizontal flue, which forces the gases and fumes from said iiue through the top iulet-opening of the condenser to the permeable screens, substantially as and for the purposes described.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 9th day of May, A. D. 1885).
