First Claim
Patent Images
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 portions 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;
the improvement comprising;
(a) motion retainer bar means connected at one end thereof to the drive bar portion and at the other end thereof to the front end of the frame, said ends being respectively connected to connection means wherein at least one of said means is adjustable to be capable of varying the distance between the connection means and the motor means; and
(b) said motion retainer bar means including a link pivotally connected between the drive bar portion and the support frame, the pivot of said link attached to said drive bar portion being slidably adjustable along the length of said drive bar such that the angle between the drive bar portion and the support frame may be varied.

Abstract
Improvements in oscillating carpet and tile strippers having a cutting blade 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. An adjustable motion retaining assembly operates to restrict the motion of the blade to decrease transverse movement and minimize centrifugal forces. A link of the motion retaining assembly is pivotally mounted between the drive bar and the frame. The drive bar mounting includes an elongated slot which allows a wide range of blade angles to be selected by positioning the link pivot in varying positions therewithin.
