NEW INDUSTRY IS NOW ESTABLISHED
W. E. Wallace Has Installed in His Place of Business Complete Plant for Manufacturing Spectacle Lens— Most Interesting Devices
Three ingenious machines with the precision of a fine watch, and mounted compactly on a special bench, which also carries an electric motor to drive them, make it a new industry. A new industry has been established in Moscow by W. E. Wallace, who has added to his optical equipment a number of machines that will contribute materially to the comfort of many wearers of glasses who occasionally are put to considerable inconvenience when they break their spectacles and have to wait several days for duplicates.
Little machines possible to cut a spectacle glass from a blank, trim the edges with mathematical precision, and drill the necessary holes for mounting in a remarkably short time.
Hundreds of optical blanks, combining all the usual combinations of spherical and cylindrical surfaces, are designed in stock, and when the combination required in any case has been determined, the blank is out on any required axis and in any case, the lens is set accurately in a machine that automatically grinds the edges smooth and brings the lens down to the standard size desired, the grinding being stopped automatically, then with a specially shaped diamond, the number of glasses is increased.  Bolts needed for mounting are needed for mounting. Creamed with a little drill press, fitted with a plate press, and the lens smooth, their locations being determined are with standard tem accurately described.
