Abstract: The invention relates to a chimney lining device which includes a shell member which telescopically embraces the exterior of a bell member. A shell member of desired dimensions may be used in conjunction with a standard sized bell member for the lining of various sized chimneys. Both the bell member and the selected shell member are formed of one-piece construction enhancing the durability and performance of the chimney lining device. During use, the invention is generally lowered to the bottom of a chimney whereon a masonry mortar compound is deposited within the chimney covering the chimney lining device. The chimney lining device is then activated causing the vibration of the bell member and the shell member. The chimney lining device is then slowly raised within the chimney, which causes a uniform and compacted thickness of masonry mortar compound to be deposited to the interior walls of the chimney.
