Device for lining or repairing offset chimneys including a reticulated centering device with an upper and lower centering guide

A device for repairing or relining an offset chimney, comprising:

• a) a spreader assembly comprising a spreader blade configured to spread a chimney repair material over the inner wall of a chimney as the spreader blade is pulled through the chimney;
• b) a pull assembly extending upward from the top of said spreader blade for a distance of at least 12 inches, said pull assembly being connected at an upper end to a device effective for pulling the spreader blade assembly upward through a chimney when the spreader blade is loaded with a repair material, and being connected at a lower end to said spreader assembly;
• and
• c) a reticulated centering device for keeping the pull assembly centered in the chimney when the spreader assembly is moved through a chimney offset;
• said reticulated centering device having an upper portion comprising a first plurality of rods and defining an upper centering guide, wherein each of said first plurality of rods has a first end connected to an upper portion of said pull assembly, and a second end connected to a lower portion of said pull assembly, and a lower portion of reticulated centering device comprising a second plurality of rods and defining a lower centering guide, wherein each of said second plurality of rods has a first end connected to said spreader blade, and a second end connected to said spreader blade, with said first plurality of rods at least partially overlapping said second plurality of rods;
• wherein said upper portion and said lower portion are reticulated with respect to each other such that upper centering guide may be angled with respect to lower centering guide, thus allowing the upper set of rods to begin turning in a bend in a chimney offset before the lower set of rods begins turning in that bend.
