Abstract

7762. John, H. April 26. Chimney tops.-A short pipe f, changing from square section at a foot flange 8 to round section at the top, rests on the brickwork, and is secured by four internal foot-plates 3 loosely connected by angle-pieces 2, in which holes 4 with burred lips 5 and teeth 6 are punched to bite the mortar of the lining and the second brick course. Each footplate is also formed with a cross-rib 7, to form a similar rib in the mortar lining. A rotary hood, composed of two steep segments a, b connected by a strip g, is supported over the pipe by a pivot pin s, set in a bridge l<1>, and rising into a socket c which is riveted to a vertical vane d on the upper segment. A tightfitting but frictionless collar t within the hood fits the thickened base of the pivot pin. The hood and vane are stiffened by ribs 13 and 14. The steep form of the hood and vane allows of easy packing within the pipes for transit, and enables the tops to be used on chimneys set close together. In a modification for use on a tallboy, the foot plates are replaced by a continuation of the pipe having spring ears cut in it.
