UNITED STATES PATENT OFFICE.
DANIEL FORBES, OF MERIDEN, CONNECTICUT.
POWDER FOR POLISHING GLASS.
SPECIFICATION forming part of Letters Patent No. 262,034, dated August 1., 1882 Application filed June 19,1882. (No specimens.)
To all whom it mag concern:
Be it known that I, DANIEL FORBES, ot' Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Powders for Polishing Glass;
with a quantity of water into a pasty condition, commonly called putty. It is applied to the polishing-wheel while revolving, and, owing to the rapidity with which the wheel revolves, (four to five thousand revolutions per 1ninute,) a considerable quantity is thrown off in the form of dust,which is very injurious to the health of the operatives.
The object of my invention is to prepare a powder and give to it a specific gravity so great that it will not rise and mingle with the atmosphere, but, on the contrary, will fall at once, and without imparting any deleterious effects to .the surrounding atmosphere; and my invention consists in a powder composed of lead, tin, and copper, in the proportions and manner hereinafter described.
I take sixty parts of lead, thirty of tin, and
fifteen of copper, all calcined, ground, and sifted, so as to be as fine as possible to make it. I mix these ingredients with waterto the consistency of soft putty, or about the same consistency as the powder usually employed. The putty thus prepared is applied to the polishing-wheel in the usual manner. Combiningrthe copper with the tin and lead holds the particles together and gives the dust which escapes from the wheel a specific gravity so great that it falls at once upon its escaping from the wheel, and no dust arises from it, as in. the use of the lead powder. Again, the
copper gives to the surface polished a better or more brilliant appearance than the use of the lead and tin without the copper, so that not only does my invention aveid the healthdestroying character of this work, but produces a better result upon the surface polished.
While I have specified the proportions of the ingredients of the powder as sixty of lead, thirty of tin, and fifteen of copper, I do notwish to be understood as confining myself to this precise proportion of parts, as it may be varied to a considerable extent.
What I claim is-' The herein-described glass-polishin g powder, composed of lead, tin, and copper, calcined and ground, substantially as described.
DANIEL FORBES.
