Oscillating carpet and tile stripper
First Claim
1. A carpet and tile stripping machine comprising:
- a support frame;
motor means mounted on said frame;
said motor means including eccentric means driven by said motor means to produce orbital motion in a substantially horizontal plane;
handle means connected to the rear portion of said frame for guiding and maneuvering said carpet stripping machine;
a cutting blade mounting assembly positioned on said frame for orbital movement in a substantially horizontal plane, said assembly having an elongated drive bar portion and a transversely extending cutting blade mounting portion;
said elongated drive bar portion being operatively connected to said eccentric means with said cutting blade mounting portion being positioned beyond the front of said frame whereby the cutting blade portion is driven in an orbital, substantially horizontal path by said eccentric means; and
means connected to the drive bar portion at the front end of the frame for restricting the movement of said bar portion at the front end of the frame to reduce the effect of centrifugal force on said blade mounting assembly.

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.
