' UNITED STATES PATENT OFFICE.
L. BRANDEIS, on NEW YORK, N. Y.
' IMPROVEM E'NTlN PROCESSES OF MAKING BRONZE-POWDERQ.
Specification forming part of Letters Patent No. 8,365, dated September 13, 1851.
. To all whom it may concern:
Be it known that I, LnoPoLn BRANDEIS, in the city of New York, State of New York, have 7 invented a new and Improved Mode of ProducingBronze-Powders, by hand, water, steam, or any other power, and givin g the same a handsome, bright appearance; and I do hereby declare that the following is a full and exactde scription thereof.
The nature of my invention consists-improducing the powder by rolling it between steel or iron tempered rollers, instead of the old producing (kept secret) to beat the mctalto Dutch leaf and grinding it, to give it a bright and brilliant surface by covering the bronzewith soap instead of grease and oil, and polishing the surface by application of polished rollers.
Toenable others skilled in the art to make use of my inven tion, Iwill proceed and describe its construction and operation, also the old proceeding.
. The making of bronze-colors has been parried on in two places in Germany for the last von'ehundred and fifty years, and is still kept a secret there. As Fiirth and Nuremberg, in Bavaria, are-the'only places in the world where metal-beating is carried on to any great extent, and the waste of the leaf is used for making bronze, they supplied the whole known world. Their expensive process is as follows:
After the metal has been reduced by waterpower to a ribbonof a thinness of one-sixth of an inch it is beat with iron hammers of twentytwo pounds each till about one-twelfth of an inch thick, annealed, cut in square pieces of one and a. half inch, laid between parchment, and
'beat two hours. Then it is taken out, annealed after wrapping it up in a stout piece of rolled brass, cooled between sand, cleaned, and cut again in square inch pieces. Then it is filled inthe gold-heaters skins and'beat until reduced to the thin leaf, commonly called Dutch or metal leaf. The cuttings and waste leaf are used now for grindin g, after it was brushed through a sieve. Then it is washed out, moved slowly and equally for an hour to settle the metallic parts on the bottom of a basin containing six pounds, then dried. For giving it brilliancy and to protect it against the infiuence of air, they cover it with grease over a coal-fire. Some even grind 'it with oil and take the superfluous oil outagain by hydraulic pressure.
Y My proceeding-is; I take ship-metal(sheeting) or any other-rolled copper or composition of copper,,zinc, and tin, break this down by iron or steel rollers to a powder, mix this with gum-arabic and water, grind it anhour, wash it out, and dryit. After this I takehalf an ounce of white Windsor or any other white I soap, scrape it under the bronzc, pass the mix- 2. The application and manner of application of soap to make the bronze bright and brilliant and durable. V
' BRA NDEIS.
