US Patent 7493931 Vibrating tile setting tool

A light weight vibrating tile setting tool, optionally having a self-contained power supply, vibrates at high frequency while setting/leveling tiles during a tile installation process. The tool comprises a housing which houses a vibration mechanism which includes a motor. An off-set weight 75 is attached to an output shaft of the motor. Rotation of the shaft, and off-set weight, causes the entire tool to vibrate. Ratio of frequency of vibration to mass of the tool is at least 200 vibrations per minute per pound mass. The high frequency of vibration causes a tile, to which the tile setting tool is applied, to be easily manipulated, by the user of the tile setting tool, into its set location in an array of such tiles.
