ING METAL AR William G. Balz,
POLISH FINISH-- AND METHOD said William G. Balz alz, Kalamazoo, Mich.
Claims. (Cl. 51 2s2) This invention relates to improvements in tumbling material for polish finishing metal articles and method.
The main objects of this invention are:
First, to provide a "wet polishing or burnishvery widely used.
Third, to provide a not only produces a highly satisfactory luster or tion as compared to commonly used wet materials and methods.
Fourth, to provide an improved method of polishing metal I treatment.
The applicants are aware and have had extended experience for many years in the practice of the so-called wet method of burnishing ing balls as barrel.
A quite satisfactory luster may be had by this method but sharp edges on the cation, while highly desirable for certain types of work is not as desirable as the material of this application for certain types of work or certain results.
articles through tumbling barrel In the invention of this application, we employ as polishing or abrading elements, irregular fragments of crushed stone, pref ably limestone,
longer dimensions.
These irregular fragments of with the use of nishing method followed by the ball polishingmethod. v
While the proportions given of two-thirds and one-third steel balls is a desirdominating material. Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:
1. A tumbling material for polishing metal articles comprising irregular fragments of crushed the proportion of two-thirds crushed limestone and one-third steel balls and the water and soap being of such proportion as to provide a substantialflooding volume of soapy water.
2. A tumbling material for polishing ta a ticles comprising irregular fragments of crushed limestone of a plurality of sizes and shapes and roughly of the order of one-eighth inch to one and a half inches in longer dimensions, andsoap and water, the water and soap being of such proportion as to provide a substantial flooding volume of soapy water for the crushed stone and the articles being polished. a
3. The method oi. polishing'metalconsisting of tumbling barrel treatment of the articles to be polished in a tumbling material comprising irregular fragments 01 crushed limestone of various sizes and shapes with a soapy fluid in such proportions relative to the crushed stone and the eluding a large mass of irregular fragments of fractured limestone of the order in size of /2 to 1 /2 inches, a mass of metal polishing elements? 15 and a liquid in flooding volume.
