E. G. MERRILL AND A. W. WILLARD, OF- OHARLESTOWN, VERMONT,
ASSIGNORS TO E. C. MERRILL.
Letters PatcntNo. 95,824, dated October 12, 1869.
I IMPROVED COMPOSITION FOR EMERY-WHEELS AND OTHER ABRADING-IMPLBMENTS.
The Schedule referred to'in these Letters Patent and making part of the same.
I To all whom it may concern.-
Be it known that we, E. C. MERRILL and A. W. WILLARD, both of Oharlestown, in the county of Orleans, and State of Vermont, have invented an Improved Composition for Emery-\Vheels and other Abrading-Tools; and we do hereby declare that the following is a description of our invention sufficient to enable those skilled in the art to practise it.
Our invention has reference to the manufacture of emery-wheels and other abrading-tools; and
The invention. consists, primarily, in a grindingwheel, or other tool, made of a mixture of emery, or other abrading-powder, and a sand or stone powder, of inferior ..hardness, artificially united by a suitable,
'cementitious agent, the composition being moulded I of emery and five ounces of fine quartz or sand, and
mix with the emery and sand about eight ounces of oxide of zinc.
Having incorporated these ingredients well together, we add seven or eight ounces of chloride of zinc, or enough to moisten well the whole mixture, with which mixture we then fill the mould, tarnping the material well into it, so as to fill every part, and compact the whole well together. I
We then leave the material in the mould and in twenty-fourlrours it will have become hard and stonelike, and will be ready for use.
These proportions, and the method of procedure, may of course be varied, as circumstances may require.
By this process we obtain avery enduring wheel, and one which wears away very evenly and perfectly.
Our object in employinga material of inferior hardness, mixed with the main grinding-agent, is to keep the sharp edges of the harder material always prominent, and prevent the face of the stone from wearing smooth, as it always inclines to do where the grinding-powder is of uniform hardness, or the grains are united by a gum, or animalor vegetable cementitious agent.
In uniting abrasive powder to form a grinding-wheel or other abrading-tool, we have found that we can make a very enduring and comparatively cheap article, whether the grains be of uniform or of comparative hardness, by using abrasive powder, united by an oxide and a chloride of zinc, the united mass being
