UNITED STATES PATENT OFFICE.
CHARLES MARIA PIELSTIOKER, OF LONDON, ENGLAND, ASSIGNOR TO THE STEEL ABRASIVES COMPANY, OF NEW YORK.
MANUFACTURE OF SUBSTITUTE FOR EMERY-WHEEL'S.
SPECIFICATION forming part of Letters Patent No. 621,702, dated March 21, 1899. Application filed August 9, 1898- Serial No. 688,198. (No specimens.)
T0 allwhomft may concern: Be it known that 1, CHARLES MARIA PIEL- STICKER, mining engineer, of London, England, have invented certain new and useful Improvements in the Manufacture of a Substitute for Emery-Wheels, of which the following is a specification.
My invention relates to'improvements in the manufacture of a substitute for emerywheels; and the object of the invention is to produce a substitute suitable for a wheel to be utilized for abrasive and polishing purposes which will be sufficiently hard so as not to wear down too rapidly; and it consists in the process hereinafter more particularly explained.
Heretofore I used to mix iron-sand, which is magnetic iron ore reduced by-natural agencies, such as water or frost, with a binding material and form a mixture in a mold under pressure and heat into a wheel in asimi-' lar manner as ground emery is formed into wheels for abrasive and polishing purposes. It has been found that although such wheels worked well and were very useful for many purposes, yet for others they were not sufficiently hard and wore down too rapidly. My improvement results in removing this defect and rendering the wheels a great deal harder and more durable. For this purpose I place iron-sand after the removal of silica or other extraneous matters into a crucible, together with a quantity of pulverized carbonaceous matter sufficient to reduce the iron-sand to the metallic state.. I also preferably add to the mixture of iron-sand and carbon a substance yielding phosphorus to the iron, such as bone-ash, of which about three per cent. is added, which has a tendency to render the iron harder. After covering the crucible I heat the same in a furnace until the iron-sand is reduced to the metallic state. I then empty- It must be further carbon and absence of air into a molten mass, 5 5 but that a bright-red heat, which will not melt iron, is suflicient to reduce oxid of iron in the shape of iron-sand to the metallic state, leaving the product in the shape of finely-divided particles, as it originally was. The product is then mixed with a binding material, such as vulcanized rubber,. and formed in a mold under heat and pressure into the shape of a wheel which is of great hardness and serves formany purposes for which the much more expensive emery-wheels are now used. Instead of rubberas a binding material to accomplish the molding of the wheel I would alternatively mix the product first with silicate of soda and next with a solution of chlo- 7o rid of calcium. By the reaction produced I would form a silicate of calcium, a binding medium of great strength and hardness. The chlorid of sodium produced by the reaction may be removed by immersing the wheel in water.
Should it not be desired to form the product into a wheel, such material before or after being reduced to the metallic state, as hereinbefore described, may be pulverized to a greater degree of fineness by passing it between iron rolls or in any other suitable manner. When thus pulverized, the powder may be utilized as such or may be suitably spread on cloth to be used the same as emery-cloth or on paper for analogous use, as may be desired.
lVhat I claim as my invention is 1. In the manufacture of a substitute for, emery products the process herein described consisting in purifying the iron-sand, heating the purified iron-sand in the presence of carbon to redness, and then immersing'the redhot iron particles in cold water, on the top of which rests a thick layer of oil as set forth.
2. In the manufacture of a substitute for emery, the process herein described, consisting in purifying the iron-sand, mixing in a crucible, the purified iron-sand and pulverized carbonaceous matter to reduce the iron 10:) ore, and adding thereto a phosphorus yielding substance to harden the iron, heating the same, and then immersing the iron particles in a cold liquid, substantially as described.
CHARLES MARIA PIELSTIOKER.
