Lubrication of oscillating head elements for floor stripping machines and method of using the same

This invention relates generally to floor stripping devices, and more particularly concerns improvements in the driving and blade support means for same. Apparatus usable in power-operated floor stripping apparatus that includes a frame, a drive carried on the frame, wheels supporting the frame, a handle to guide the frame, and a cutting blade carried by a head which is pivotally mounted to the frame, the apparatus comprising a lightweight rugged connecting element having a first tubular part and a second tubular part, those parts having spaced, parallel axis, the second tubular part pivotally connected to the head. There are two axially spaced eccentrics on the drive shaft, which rotate within two annular bearings carried by the first tubular part. Spiral grooves are sunk in the external surfaces of said eccentrics to communicate with said lubricant receiving space to receive lubricant for distribution along said eccentrics to the annular bearings.
