"Be it known that I, GEORGE W. CASE, a citizen of the United States, residing at Lestershire, in the county of'Broome and State of New York, have invented certain new and useful Improvements in Metal Com ounds for'the Removal of Boiler-Scales, which .lIO
ing ingredients: antimony, aluminum, bis- .muth, copper, lead, tin, mercury and ZlIlC, to be used together or in groups of two, or
more metals; the objects of these different combinations are for the purpose of meeting the different steam pressures in boilers, as before mentioned herein. Different steain pressures require a different combination of the ingredients. These metals are combined, for general use, in the following pronum, 2 parts bismuth, 1 part copper, parts -lead, 3 parts mercury, parts tin, parts zinc.
The proportion of the different metals entering into this compound, may be varied in amount, in accordance with the different amount or degrees of steam pressure; The actual quantity placed in a boiler at any given time will depend on the horse power, steam pressure, and desired. running period between changes. These ingredients above named are first melted separatelyand then mixed together in the molten state when in this state and thus mixed together, the com' pound is placed in molds and cast into balls, or'other forms and shapes. When in the form of balls, they are about 2 inches in diameter and about one lb in weight.- The balls are placed within a metal container, which is then suspended within the steam boiler foruse.
The action-of the boiling water .and the steam pressure soon disintegrates the metal compound: it dissolves, and the water he comes impregnated with it. The quantity of the metal compound and the proportion of the ingredients entering into'the compound,
depend upon the horsepowers of the boilers,
the com osition of the water .and the steam power o1 the boiler; the water being purified by the action of the dissolvin prevents pitting, priming or ioaming of the boiler.
Having thus described my invention or discovery, what I claim as new and desire to secure by Letters Patent, is:
let: The herein described composition of matter, consisting of antimony/aluminum, bismuth, copper, lead, mercury, tin, zinc substantially as described andfor the purpose specified,
2. The herein described composition of matter consisting of 8 parts antimony, 4 parts aluminum, 2parts bismuth, 1 part copper, 10 parts lead, 3 parts mercury, 25 parts tin, 45 parts zinc and for the purpose of removal and prevention of scales in steam boilers, and other receptacles in which steam.
In testimony'whereo'l I have afiixedmy signature,.in presence of two witnesses.
