Patent number: 4303224Abstract: A lever-type tool for adjusting the camber and caster of automobile wheels. A fulcrum point of a lever of the third class is provided on the tool which bears against an automobile frame to provide a force on the end of the automobile's wheel pivot bar to thereby move the pivot bar and its attached arm relative to the automobile frame, the arm in turn being attached to the upper portion of a wheel. Opposed ends of the pivot bar may be individuallyadjusted by this tool which changes the camber and caster of the wheel acting through the arm. A force applying lever forms a part of the tool to thereby multiply the applied force and because the position of the handle can be adjusted relative to the remainder of the tool, it is possible to accommodate the various possible spaces between the fenders and tires of different vehicles.Type: GrantFiled: January 29, 1980Date of Patent: December 1, 1981Inventor: Leonard G. Nelson

Patent number: 4269393Abstract: A tree-felling implement is disclosed, which is particularly effective for felling frozen trees. The implement is of the type comprising flat plate with a front transverse straight edge, a lever arm being rigidly secured to the top face of the flat plate and extending upwardly at an acute angle rearwardly from the flat plate. This implement is characterized by the provision of a bite member which downwardly projects from the bottom surface of the plate along the front transverse edge. Said bite member has a generally rectangular cross-section providing parallel front and rear flat side faces substantially perpendicular to the bottom surface of the plate and a flat edge surface substantially parallel to the bottom surface of the plate. The plate and the bite member are thin enough to be inserted into a saw kerf made in the trunk of a frozen tree.Type: GrantFiled: November 27, 1979Date of Patent: May 26, 1981Inventor: Honore Michaud
