Definitions
- Hitherto aluminium powder has generally; been made by rolling cast rods out into leaves after repeated glowing or heating and then stamping the leaf metal. Experiments have also been made with waste filings, &c., but these experiments have thus far had no good resultbecause the powder was not soft enough.
- the present invention is based on the observation that thin-walled bodies of aluminium which are produced when liquid aluminium is poured into water are suitable to be comminuted directly into powder by stamping, and this powder leaves nothing to be desired as to softness and ductility.

LEONHARDT OTT AND HANS RIFFELMAOHER, OF BOTH, GERMANY, ASSIGNORS TO THE BRONZEFARBENWERKE AOTIEN GESELLSOHAFT, VORMALS CARL SCHLENK, OF SAME PLACE.
PROCESS OF MAKING ALUMINIUM PAINT.
SPECIFICATION forming part of Letters Patent No. 642,358, dated January ;30, 1900.
Application. filed July 21, 1899. Serial No, 724,712. (No specimens) To all whom it may concern:
Be it known that we, LEONHARDT OTT and HANS RIFFELMAOHER, subjects of the Emperor of Germany, and residents of Both, in the Kingdom of Bavaria andGerman Empire, have invented certain new and useful Improvements in Methods or Processes of Manufacturing Aluminium Powder, of which the following is a full, clear, and exact specification.
Hitherto aluminium powder has generally; been made by rolling cast rods out into leaves after repeated glowing or heating and then stamping the leaf metal. Experiments have also been made with waste filings, &c., but these experiments have thus far had no good resultbecause the powder was not soft enough.
The present invention is based on the observation that thin-walled bodies of aluminium which are produced when liquid aluminium is poured into water are suitable to be comminuted directly into powder by stamping, and this powder leaves nothing to be desired as to softness and ductility. In producing it according to our discovery we pour the liquid aluminium into water, which causes it to solidify in irregular forms of extreme thinness. These small or thin pieces are then brought under a stamping-press of ordinary construction or similar comminuting apparatus, whereby they are converted into a fine powder. 7
By the above process the lengthy preliminary operations usually required, necessitat ing skilled operators, are dispensed with.
Having thus described our invention, what we claim is-- The herein-described process of producing aluminium powder consistingin pouring fluid aluminium into water and then comminuting the thin irregular-shaped pieces so formed, substantially as described.
In testimony that we claim the foregoing as our invention we have 'signed our names in presence of two subscribing witnesses.
LEONI-IARDT OTT. HANS RIFFELMAOHER.

JULIUS GERTERBEIN, ERNST EISENBERG.
