"Our invention has for its object to furnish an improved emery-wheel machine, which shall be so constructed that the emery-wheel may be turned into any position that the form of the work being ground may require without stopping the wheel or checking its speed, and shall be so simple in construction and convenient in use, being so constructed as to expand and contract as the band is twisted and straightened in using the machine, and which will enable the bands to be readily slackened and tightened as may be required."
