Abstract
A removable extension for thimbles used in baghouse installations. The extension, which projects below the main body of the thimble, insures that gas entering a filter bag connected to the thimble will have a flow direction aligned with the bag axis such that particulate matter entrained within the gas stream will not impinge on the sides of the filter bag and cause excessive wear. The extension, which need not be secured to the main body of the thimble, abuts the inner wall surface of the thimble and rests on an annular flange formed in the upper portion of the thimble.
