UNITED STATES JOSEPH A. MENARD, 0F SEATTLE, WASHINGTON.
ABRASIVE COMPOUND.
No Drawing. Application filed June 30, 1919, Serial No. 307,590. Renewed May 12, 1921. Serial No. 469,032.
To all whom it may concern:
Be it known that I, JosErH A. MENARD, a citizen of the-United States, and resident of the city of Seattle, county of King, State of Washington, have invented certain new and useful Improvements in Abrasive Compounds, of which the following is a specification.
My invention consists of a compound which is intended for use as a grinding or polishing compound, especially for use on metal surfaces, as for grinding in bearings, polishing surfaces, etc.
The object of my invention is to produce a compound of a reasonable cost which shall also be of superior quality and one which may be used safely for such purposes as grinding in bearings and other work which demands a superior product.
My invention consists in the use of certain ingredients combined in the manner and in substantially the proportions which will be herein described and particularly set forth in the following specification.
As the base of my invention I first form a compound which is not, of itself, a satisfactory grinding compound, and add to this other abrasive ingredients which vary according to the character of the service to which it is intended the compound shall be put. This base compound serves to blend together the particles of the abrasive material so that. it will work satisfactorily, also to prevent damage in case some of the compound is left in a bearing. In fact, the final compound may be said to be not injurious to a bearing, as it will, after a certain period of use, have its abrasive particles coated with certain of the ingredients of the base compound, so that it loses its cutting qualities.
The finished product as I have heretofore made it, is in the form of a dry powder and when used is mixed with oil or water. In grinding bearings, the product is mixed with oil or water and introduced into the bearings and the shaft rotated.
This compound will cut and grind babbitt,
bronze and like bearing metals, but will not appreciably cut steel. After a limited amount of use in a bearing it appears to lose its cutting power and works out. It appears under a strong magnifying glass to form minute masses which are coated with a film of the material removed from the bearings and certain of the ingredients of the compound, such as the graphite, the potash and sodium. These substances eventually destroy the cutting action of the material to such an extent, that it is not strictly essential to clean the compound from the hearing when there is any opportunity for it to work out v by use.
This material is excellent for grinding or polishing any object, such as valves and for cleaning steel surfaces. As I have theretofore made the base compound'I take two parts by measure of pure white lead and in this thoroughly incorporate onepart by measure of lamp black and a small quantity of flake graphite or plumbago, and of sodium bicarbonate, say about. one eighth as much of each as of the lamp black, and of potash or potassium oxide, about one third as much as of the sodium bicarbonate.
This forms a base compound to which is added an abrasive substance or substances, which differ in accordance with the use to which it is to be put. The abrasive substance which I most largely employ, is ground glass. This is ground to pass a 120 mesh screen or finer. A sufficient amount of this is added to constitute from 55% to .materials.
Obviously, less than all the ingredients named may be employed, the results being measurably satisfactory even with the use merely of lead and silica, butlead, silica and sodium, or lead, silica, graphite and sodium may be used with more completely satisfactory results than lead and silica alone.
The lead, preferably white lead though red lead may be used, serves in a measure as a vehicle or carrier for the silica or other abrasive. It also serves, as the compound is subjected to the rubbing action of the relatively moving or moving and fixed parts, to coat the abrasive particles and render them non-abrasive, or even to make them serve in a limited degree as a lubricant.
Graphite increases the lubricating properties of the mixture as the abrasive gradually wears or breaks down, and the same is true of the sodium.
WVhile the proportions stated are those found most eifectlve in practice, it is to be understood that I. do not mean to limit myself closely thereto, the nature of the surfaces to be treated making it possible or exp'edient to employ compounds of widely l0 varying proportions.
\Vhat I claim as my invention is:
