Claim 10

In a chimney having an outer column with an exterior and inner surface, an inner lining spaced therefrom and having a lower end, and breeching means communicating with said lining, the improvement comprising: an insulated breeching member comprising a tubular element generally in line with the inner lining, at least two lateral tubular elements disposed generally horizontally or at a slight obtuse angle to said vertical tubular element; said breeching member being symetrical or substantially evenly balanced about its vertical axis; said lateral tubular elements extending through the outer chimney column to form breeching entries; and suspension means coacting with the outer chimney column and the tubular elements for suspending the breeching member within the chimney at the lower end of the brick lining.

Claim 11

In a chimney having an outer column with an exterior and inner surface, an inner lining spaced therefrom and having a lower end, and breeching means communicating with said lining, the improvement comprising: an insulated breeching member comprising a tubular element generally in line with the inner lining, at least two lateral tubular elements disposed generally horizontally or at a slight obtuse angle to said vertical tubular element; said breeching member being symetrical or substantially evenly balanced about its vertical axis; said lateral tubular elements extending through the outer chimney column to form breeching entries; and suspension means coacting with the outer chimney column and the tubular elements for suspending the breeching member within the chimney at the lower end of the brick lining.

Claim 12

In a chimney having an outer column with an exterior and inner surface, an inner lining spaced therefrom and having a lower end, and breeching means joined to said lining, the improvement comprising: a breeching member comprising an upright tubular element generally in line with the inner lining, and at least one lateral tubular element, said lateral element extending through the outer chimney column to form a breeching entry; and suspension means coacting with the outer chimney column and the upright tubular element for suspending the breeching member within the chimney at the lower end of the inner lining.

Claim 13

In a chimney having an outer column with an exterior and inner surface, an inner lining spaced therefrom and having a lower end, and breeching means joined to said lining, the improvement comprising: a breeching member comprising an upright tubular element generally in line with the inner lining, and at least one lateral tubular element, said lateral element extending through the outer chimney column to form a breeching entry; and suspension means coacting with the outer chimney column and the upright tubular element for suspending the breeching member within the chimney at the lower end of the inner lining.

Claim 14

A chimney construction comprising an outer column and an inner liner radially inwardly spaced therefrom; the improvement comprising: a support for said chimney disposed in direct supporting relation to at least said column, a base extending into the space between said liner and column; and thermally expandable and contractable means mounting said liner with respect to said base for accommodating expansion and contraction thereof.

Claim 15

A chimney construction comprising an outer column and an inner liner radially inwardly spaced therefrom; the improvement comprising: a support for said chimney disposed in direct supporting relation to at least said column, a base extending into the space between said liner and column; and thermally expandable and contractable means mounting said liner with respect to said base for accommodating expansion and contraction thereof.

Claim 16

The invention according to claim 11 wherein said base member extends to and is supported from said column, and wherein said liner is seated upon said base.

Claim 17

The invention according to claim 12, and a breeching member having a thermal connection with said liner and extending through an opening in said column.

Claim 18

The invention according to claim 11, and a tubular breeching element extending through said column, and said liner having a collar, and said breeching member being hung from said collar for communication with the liner and expanding and contracting relative thereto.

Claim 19

The invention according to claim 14, and resilient means floatingly suspending said breeching member from said chimney.

Claim 20

The invention according to claim 14, and said breeching member having a collar seated upon said liner collar.

Claim 21

In a chimney having an outer column with interior and exterior surfaces and upper and lower end portions, a base within the lower end portion, a liner within said column spaced from said interior surface and seated upon said base, means supporting said base, a tubular breeching member suspended from said base, and connecting means providing for relative thermal expansion and contraction between said base and said breeching member.

Claim 22

In a chimney having an outer column with interior and exterior surfaces and upper and lower end portions, a base within the lower end portion, a liner within said column spaced from said interior surface and seated upon said base, means supporting said base, a tubular breeching member suspended from said base, and connecting means providing for relative thermal expansion and contraction between said base and said breeching member.

Claim 23

The invention according to claim 17, and said breeching member comprising a vertical tubular portion in alignment with the liner and having an upper end portion overlapping said base and thereby providing said thermal connecting means.
