The chimneyl structure, illustrated' inthe dinv'rings,and: consisting essentially of the` fireplace l with its i'irebox 2, ornamentalfad.. ings :3, and shelf 4, and the chimney flue 5f:

ney fine. The vfirebox. 2 is .usually provided4 Withanaarched fire brick'backing 7.Which exe tends from the base ofthe firebox in curved 805 form upivardly'andforwardly to the .chim-- ney throat 8I forming behiIid-the upperpoi'-P tion of this backing; a shelf or ledge 195 for; di rectiiig the return draft passing downwardly at the rear, side ofthe chimney liuc. At. the lateral sides oftliefirebox andat the. upper ends of the side Walls theieof,are providedsupporting ledges 10` which are` at theisame elevation as the upper end .ofI the firelorick 'facing 7, as shown in Figs, 1' and` 2. vMy

chimney throat liner,v designated 11, v isy posi-l tioned Within the throat portion lof'theichimico@ g Y may be laid against and constructed upon the Y VMy chimney throat liner, in its preferred form of construction, is made of terra cotta and molded as a single and complete unit in the form shown. This form is a hollow truncated pyramid having a flat and vertical rear wall 1l, a front wall llb which is in the shape of a trapezoid and inclined backwardly and upwardly, and lateral side walls, alsov trape# zoidal in shape, inclined inwardly and` upwardly and joining at its edges the lateral edges of the rear and front'walls, as vindi- V Y cated by 11C. The inner faces of the walls forming this liner connect the ireboX, at the upper portion thereof, in smoothV lines and in unobstructed surfaces, with the inner faces of the flue liner 6 of the chimney flue 5.- The portion of the fireplace behind the facing 3 is usually built up of brick andthe forward wall of the chimney throat formed as steps in warious irregular form forming pockets and materially obstructing the passage of the gases of combustion and smoke to the chimney flue,'often causing the same to pass downwardlyinto the room. By Vemploying my flueliner, thebrick andlmortar forming the front and lateral sides of the throat `portion liner as a form, thus making a solid, rigid and compact structure, as well as facilitating `the construction of the chimney throat. The

front wall of the liner directs the heat away from the brick and mortar and reduces to a minimum the destructive action on the same 4pended claims.

the chimney, or upper portion of the fireplace or mantel, is eliminated. The same is true also of the'other walls forming the chimney throat.

Though l have shown and described a particular construction, combination, and arrangement ofparts and portions, l do not wish to' be limited to this particular con-V structiom'combination and arrangement but desire tolinclude inthe scope of my invention the construction, combination and arrangement substantially as set forth in the apvHaving thus j l claim as new andV desire to secure by Letters Patent is: A" Y Y l. A molded chimney throat liner open at its'lower and its upper ends, the rear wall being flat and substantially vertical, the front wall being inclined upwardly and backward described my invention, what ly from its lower to its upper end, and its side walls being upwardly convergingv with vrespect to each other and joined to the rear and front walls, Vall forming a free unobstructed upwardly converging and gradually reducing passage from its lower to its upper end, said linerbeing adapted to be telescoped over and within other liners for Astacking and economically storing the same, the inner surfaces of all walls of one liner, when stacked over another-liner", engaging the outer walls of the latter. Y

' 2. A chimney throat liner having a large rectangular opening at. its lower end and a smaller correspondingly shaped opening at itsfupper end, one wall of said liner being Asubstantially vertical and t-he other walls being inclined upwardly and inwardly from rthe lower to theupper ends of the liner, all

forming va free unobstructed upwardly converging and gradually reducing passage from its lowerto its upper end, the lower andupper supporting edges of the walls being the width of the thickness of the walls, the lower edges supporting the liner in the chimney throat and .the upper edges being adapted directly tosupport a flue liner, saidliner being adapted to be telescoped over and within other liners for stacking'and economically storing Vthe same, the inner surfaces of all walls of one liner, whenstacked'over another liner, engagingv the outer walls of the latter.

` 3. In a chimney structure, a large irebox portion, a `chimney flue liner positioned and extending above the same,-and a chimney throat liner contracted gradually from its lower to its upper end and having plain walls from its lower to its upper end, the termination of the walls at the eXtreme upper and lower ends being of the same thickness as intermediate portions, forming narrow supporting edges and upwardly converging smooth lines at the inner and outer sides of the walls, the lower end of said flue liner resting upon and being lsupported by the narrow edges of the upper end of the throat liner.

e. A. molded chimney throat liner shaped as a-hollow truncated pyramid wholly open at its upper and lower ends, said liner being adapted to be telescoped over and within other liners for stacking and economically storing the same, the inner surfaces of all walls of one liner, when stacked over another liner, engaging the outer walls of the latter.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 16th day of November, 1926. t,
