Claim 15:
16. A dampening device for dampening vibrations of a belt that drives a vehicle by applying tension to the belt, the dampening device comprising:
an elongated body constructed from a rigid material, the body defining a longitudinal axis, wherein the body extends along the longitudinal axis;
a first end of the body located at a first longitudinal end of the body;
a second end of the body located at a second longitudinal end of the body, wherein the first end is located opposite of the second end;
a mounting foot pivotally attached to the first end of the body;
a tensioning spring secured to the body and the mounting foot, wherein the tensioning spring has a first end secured to the body and a second end secured to the mounting foot;
wherein the second end of the tensioning spring forms a hook that catches a raised edge of a side wall of the mounting foot without inserting the second end of the tensioning spring into a hole in the mounting foot;
a base of the mounting foot;
the side wall of the mounting foot that extends vertically above the base, wherein the side wall of the mounting foot accepts a fastener to secure the mounting foot to the first end of the body;
a mounting aperture in the base of the mounting foot that accepts a fastener inserted vertically downward to secure the mounting foot to the vehicle;
a rotating head that secures to the second end of the body, wherein the tensioning spring biases the rotating head downwards against the belt;
a spring aperture located between the first end and the second end of the body, wherein the spring aperture is located longitudinally away from the first end of the body, wherein the first end of the tensioning spring inserts into the spring aperture;
an attachment juncture located at the raised edge of the side wall of the mounting foot, wherein the hook formed at the second end of the tensioning spring is biased against the raised edge to secure the second end of the tensioning spring against the mounting foot, wherein the raised edge is an edge of the side wall located vertically above the mounting aperture and the base of the mounting foot;
wherein the mounting foot attaches to a first side of the body located laterally of the body, wherein the rotating head attaches to a second side of the body located laterally of the body, wherein the rotating head is located on an opposite side of the body as the mounting foot.
