Latas ramY No. 83,701, dated November 3, isos.

To all whom fit may concern:

Be it known that I, JOHN ERVIN, Seur., of Princeton, in the county of Gibson, and State of Indiana, havey invented a new and .improved Fire-Place and Chimney; and I do hereby declare that the following is a full, clear, a'nd exact description thereof, which will enable those skilled in. the art'to make` and use `the sama-reference being had to the accompanyingv drawings, forming part of this specification.

This invention relates to improvement in the fireplaces and chimneys of dwellings andother buildings, whereby the re is supplied with air from beneath the ure-grate or hearth; and the invention consists in forming air-fines and orices in the jambs, as will be hereinafter more fully described. Y

Figure 1 is a sectionalfront elevation oi' a lire-place and chimney, constructed according to my invention, thesection being through the line v v of fig. 4.

Figure 2 is a horizontal section, through the line x x of fig. l. y

Figure 3 is a horizontal section, through the line y'y 'of ii l.

Figgure 4 is a vertical section of fig. 1, through the line z z. y Y

Similar letters of reference indicate corresponding parts. I p

A- is the hre-place, which may be used for burning either wood or coal. If for the' latter, a coal-grate would be adjusted thereto in the ordinary manner.

B represents the hearth.

.C is the chimney.

D represents a grated aperture through the hearth,

through which the air from the outside of the chimney passes to the iire.

Eis a hollow arch beneath the hearth, having an aperture, F, in its top, so that ashes may fall from the" the chimney.

ciple for two purposes, one for a chimney built outside, and the other for one built inside, each having a ilue arranged,y as seen in the drawing, for admitting lair into the fire-place from the external atmosphere.

H is a iiue, built in the jamb of the fire-place, for admitting air when the chimney is built up outside of the building, and J is a lue,formed in the same manner in the jamb of the irelace, extending with the chimney above the root1 of jhe building, but closed at the top, with orifices i for ladmitting air.

The air descends in this' i'lue, and enters the fireplace lthrough the orifices h and F, and grated aper- .ture I).

For the outside chimney, the air enters through the orifices l, and, passing downward through the orifices m, under the arch, is discharged into the fire-place through the aperture F and grate D.

kIn the. iiue J, there is a damper, as seen at n, for regulating the draught.

Through the' back side of the chimney there are orifices for the admission of air, as seen at o, and the ashes from'beneaththe arch may, in outside chimneys,

be removed by providing a suitable aperture therefor.

For inside chimneys, the ashes may be removed by raising the grate D. In either case, it would only be 'at long intervals that the removal would be necessary.

By this arrangement, all danger from fire on account of the ashes would be avoided.

By the introduction'of cold air from the outside, a powerful draught is produced in the irefplace and up I claim as new, and desire to secure by Letters Patent- The lues H and J, with the orifices l, m, t', k, and o, arranged substantially as and for the purposes described.
