Lubricant composition composed of high-titre soap, borax, and an inorganic compound

Claim 1

A WATER SOLUBLE LUBRICATING COMPOSITION FOR USE IN THE FORMATION OF METAL ARTICLES CONSISTING ESSENTIALLY OF AT LEAST ABOUT 15% OF AN ORGANIC LUBRICATING MATERIAL SELECTED FROM THE GROUP CONSISTING OF A WATER SOLUBLE HIGH TITRE SOAP AND A MIXTURE OF WATE SOLUBLE HIGH TITRE SOAP AND ORGANIC WATER SOLUBLE ALIPHATIC, POLYHYDRIC ALCOHOL HAVING LESS THAN FOUR HYDROXY GROUPS, AND AT LEAST TWO LUBRICATING, WATER LIBERATING HYDRATED, GLASS FORMING, WATER SOLUBLE INORGANIC MATERIALS SELECTED FROM THE GROUP CONSISTING OF METAL PHOSPHATES, METAL CARBONATES, METAL SILICATES, METAL BRATES AND BORIC ACID, ONE OF SAID INORGANIC MATERIALS BEING BORAX AND PRESENT IN AN AMOUNT AT LEAST ABOUT 40% OF THE TOTAL COMPOSITION AND GREATER THAN THE AMOUNT OF ANY OTHER INORGANIC MATERIAL PRESENT IN THE COMPOSITION, THE AMOUNT OF THE TOTAL INORGANIC MATERIAL BEING GREATER THAN THE AMOUNT OF THE ORGANIC LUBRICATING MATERIAL, THE MELTING POINT OF THE ORGANIC LUBRICATING MATERIAL BEING LESS THAN THAT OF ANY OF THE INORGANIC MATERIALS, AND THE INORGANIC MATERIALS EACH HAVING A MELTING POINT BELOW 1000*C. AND EACH HAVING A MELTING POINT DIFFERENT FROM EACH OTHER EACH INORGANIC MATERIAL BEING PRSENT IN AN AMOUNT SUFFICIENT TO PROVIDE AND MAINTAIN LUBRICATION THROUGHOUT A MATERIAL RANGE OF TEMPERATURE DIFFERENT FROM EACH OTHER, AND THE ORGANIC MATERIAL BEING PRESENT IN AN AMOUNT SUFFICIENT TO PROVIDE AND MAINTAIN INITIAL LUBRICATION UP TO A TEMPERATURE AT WHICH THE INORGANIC MATERIAL OF LOWEST MELTING POINT BECOMES OPERATIVE, WHEREBY THE COMPOSITION WILL PROVIDE PROGRESSIVE AND STEPWISE LUBRICATION OF THE METAL DURING THE FORMING OPERATION.
