A vertically elongated tool is provided including an upper head portion and a pair of downwardly divergent legs each having its upper end pivotally supported from the head portion for oscillation relative thereto about an axis extending transversely of the legs, the pivot axes of the legs being parallel, and for relative swinging movement of the lower ends of the legs toward and away from each other. A horizontally elongated control block extends between and interconnects the legs intermediate their upper and lower ends. The legs and the control block include coacting guide structure attaching the ends of the control block to the legs for guided movement therealong, whereby upward and downward movement of the block along the legs swings the lower ends of the legs away and toward each other, respectively, the head and control block each including anchor structure for anchoring one end of an elongated tension and suspension member section thereto and the remote sides of the lower ends of the legs including structure for frictionally gripping the internal surfaces of a hollow flue lining block.
A flue pipe installation tool including an upper head portion, a pair of slightly downwardly divergent elongated and substantially longitudinally straight legs each having its upper end pivotally supported from said head portion for oscillation about an axis extending transversely of said head portion and the legs for relative swinging movement of the lower ends of the legs toward and away from each other, said legs each including a longitudinal slot formed therein, a horizontally elongated control block extending between and interconnecting said legs intermediate their upper and lower ends, each end of said block including pin means slidably received in the corresponding leg slot, whereby upward and downward movement of said block along said legs causes the lower ends thereof to swing away and toward each other, respectively, said head and control block each including anchor means for anchoring one end of an elongated suspension member section thereto, the pivot axes of said legs relative to said head portion being spaced horizontally apart in parallel relation, the remote portions of the lower ends of said legs including resilient portions thereof for frictionally gripping the internal surfaces of a flue lining block.
