Abstract
Abstract The invention relates to an extruded lead wheel balancing weight for use with pneumatic tires, particularly for automobiles, and particularly for a rim having a tapered wheel seating flange. The weight is tapered across its width so as to take a conical shape along one surface when the weight is formed to the circular configuration of the wheel flange to thereby conform to the tapered shape of the wheel flange and remain parallel to the rotating axis of the wheel. The weight is normally extruded and moldable by finger pressure, and is held in place to the wheel flange by a double faced pressure sensitive adhesive foam.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
118 words
A balancing weight in combination with a rotatable pneumatic wheel which comprises: an elongated lead based strip weight having a trapezoidal shape in cross-section with two long non-parallel sides and two substantially parallel ends, one end being shorter than the other, a drop center rim mounting a pneumatic tire to constitute the wheel, said rim having a tire supporting flange attached to the drop center and bead retaining edges on the flange to mount the tire and where the flange is conical in shape tapering outwardly from the drop center rim, and means to secure the strip in position to radially inward surface of the flange with the shorter end adjacent and substantially parallel to the drop center.
Claim 2
Dependent Claim
118 words
A balancing weight in combination with a rotatable pneumatic wheel which comprises: an elongated lead based strip weight having a trapezoidal shape in cross-section with two long non-parallel sides and two substantially parallel ends, one end being shorter than the other, a drop center rim mounting a pneumatic tire to constitute the wheel, said rim having a tire supporting flange attached to the drop center and bead retaining edges on the flange to mount the tire and where the flange is conical in shape tapering outwardly from the drop center rim, and means to secure the strip in position to radially inward surface of the flange with the shorter end adjacent and substantially parallel to the drop center.
Claim 3
Dependent Claim
18 words
A combination according to claim 1 wherein the strip weight is extruded and is moldable by finger pressure.
Claim 4
Dependent Claim
27 words
A combination according to claim 2 where the means to secure is pressure sensitive adhesive covering the full engaging surface of the strip weight to the flange.
Claim 5
Dependent Claim
54 words
A combination according to claim 3 where the trapezoidal shape of weight in cross-section is such that when the weight is conformed to the conical shape of the flange, the weight takes the shape of a segment of the cone, and the sides remain parallel to each other throughout the length of the weight.
Claim 6
Dependent Claim
51 words
A wheel balancing weight extruded from finger pressure moldable lead which has a trapezoidal shape in cross-section with two long non-parallel sides, and two short parallel sides, and double faced pressure sensitive foam means secured over the entire surface of one of the sides defined by one of the nonparallel sides.
Claim 7
Dependent Claim
51 words
A wheel balancing weight extruded from finger pressure moldable lead which has a trapezoidal shape in cross-section with two long non-parallel sides, and two short parallel sides, and double faced pressure sensitive foam means secured over the entire surface of one of the sides defined by one of the nonparallel sides.
Claim 8
Dependent Claim
19 words
A weight according to claim 5 where the other of the non-parallel sides is perpendicular to the parallel sides.
Claim 9
Dependent Claim
40 words
A weight according to claim 6 where when the weight is formed to a curved configuration whereby the other side is concave and the one side is convex, the one side forms the shape of a section of a cone.
