Description: |
| Abstract:
The process which I have adopted is an improvement of that ordinarily followed in which the conversion of blue lead into carbonate is effected by the heat generated by the fermentation of manure cooperating with the vapor of vinegar, but instead of the heat produced by fermentation I introduce steam from a steam boiler, and the vapor of vinegar produced also by artificial heat. The structure in which the conversion is effected may vary in size but for the purpose of description I give the proportions of one which I have used, and which I have found to answer the intended purpose in a very perfect manner. I build a basement usually of brick, which is thirty three feet long, twelve feet wide, and four feet high. I form two furnaces for heating boilers on each end of this basement. The furnace, and boilers for water I place in the middle of each end the boilers being five feet long by two in diameter. The boiler for acid is considerably smaller, a common hundred gallon still answering the purpose well.
Claim:
The effecting of the corrosion of the lead, and the conversion thereof into white lead by the admission of steam from boiling water, and of the vapor of vinegar, or other fluid containing acetic acid into a corroding chamber, which corroding chamber is properly charged with lead, and is surrounded in the manner herein described by layers, and banks of sawdust, tan, or other like material into, and through which layers, and banks steam from water is forced so as to enter the corroding chamber. |
