Abstract
A apparatus for removing surface coverings, includes a shaft having a first end and a second end; a sleeve slidably mounted on the first end of the shaft; a clevis pivotably mounted on a first end of the sleeve; a drive mechanism for shifting a rod between a first rod position and a second rod position relative to the shaft; and a blade mounted on the clevis and extending away from the shaft. The clevis is secured to the rod, such that as the rod moves between the first rod position and the second rod position, the clevis pivots on the sleeve, and the sleeve slides on the shaft to shift a leading edge of the blade between a first edge position and a second edge position.
Claims59
An apparatus for removing surface coverings, comprising
- a shaft having a first end and a second end;
- a sleeve slidably mounted on said first end of said shaft;
- a bracket pivotably mounted on a first end of said sleeve;
- a drive mechanism for shifting a rod between a first rod position and a second rod position relative to said shaft;
- and
- a blade mounted on said bracket and extending away from said shaft;
- wherein said bracket is secured to said rod, such that as said rod moves between said first rod position and said second rod position, said bracket pivots on said sleeve and said sleeve slides on said shaft to shift a leading edge of said blade between a first edge position and a second edge position.
An apparatus for removing surface coverings, comprising
- a shaft having a first end and a second end and having a pin mounted on said shaft proximate to said first end;
- a sleeve, having an oblong hole radially formed therethrough, extending beyond and slidably mounted on said first end of said shaft, such that said oblong hole receives said pin to restrict the sliding of said sleeve on said shaft to a length of said oblong hole;
- a bracket pivotably mounted on an end of said sleeve extending beyond said first end of said shaft;
- a drive mechanism mounted on said shaft for shifting a rod between a retracted rod position and an extended rod position;
- and
- a blade mounted on said bracket and extending away from said shaft;
- wherein said bracket is secured to said rod, such that as said rod moves between said retracted rod position and said extended rod position, said bracket pivots on said sleeve and said sleeve slides on said shaft to shift a leading edge of said blade from a lowered edge position and a raised edge position.
