ABSTRACT:
This invention relates to an oscillating carpet and tile stripper in which the cutting blade is mounted on a mounting and drive assembly which is connected to an eccentric driven by an electric motor to impart an orbital motion to the cutting blade. The end of the drive bar assembly adjacent the cutting blade is guided in translatory movement such that the movement of the cutting blade is at an angle to the frame and is slightly restricted in a transverse direction. This will decrease the effect of centrifugal force of the blade in the transverse direction of movement of the cutting blade without change of the amount of eccentricity of the eccentric to minimize vibration on the machine. The blade operates at a high rate of speed to provide a shearing action at the blade tip which rapidly removes bonded carpet or tile from a floor.
