Chimney Fire Preventer (Patent No: 351910)

Inventor: Alix, James A.

Location: Edmonton

Comments: N/A

Description: What I do claim as my invention and desire to secure by letters patent, is-

1. A fire preventer chimney cap consisting of a vertical, central flue member of any cross-section, open at both ends, and connected outwardly to a frusto-conical or frusto-pyramidal storm-band, also open at both ends and having same axis, or to a conical or pyramidal cap, by four plane, vertical, radial plates, positioned at right angles with one another.
2. In a fire preventer chimney cap, a vertical central flue member, connected outwardly by four radial plates, to a frusto-conical or frusto-pyramidal storm-band or to a conical or pyramidal cap; the base plane of said storm-band or cap being slightly below the plane of upper part and central flue member; the base diameter of said storm-band or cap being not less than about two and one half times the diameter of upper part of central flue member; the altitude of said storm-band or car above upper part of central flue member being not less than one diameter of said central flue member.
3. In a fire preventer chimney cap, a vertical, central flue member, connected outwardly to a frusto-conical or frusto-pyramidal storm-band, or to a conical or pyramidal cap, by four plane, vertical, radial plates; the lower part of said radial plates being secured inwardly to the vertical, central flue member, and projecting outward from said central flue member, and downward from the storm-band or cap so as to form a square-shaped extension below the base plane of said storm-band or cap; the upper, outward part of said radial plates being secured to said storm-band or cap; the upper, inward part of said radial plates joining by a straight, slanting line, the top edge of the central flue member to the storm-band or cap.
4. In a fire preventer chimney cap, a frusto-conical storm band - or a conical cap - connected by four radial plates to a vertical, central flue member, said flue member being corrugated lengthwise at its lower end, along a length of several inches, when it is to be adapted on a smoke stack, or a roof pipe.
