FIRE-PLACE AND CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 313,441, dated March 3, 1885.

Application filedMay E0, 1884. (No model.)

To all whom it may concern.-

Beit known that I, THEODORE O. NATIVEL, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Fire-Places and Chimneys, of which the following is a description.

Figure 1 is a side view of my improved fireplace and chimney, and Fig. 2 is a vertical section of the same on line as x of Fig. 1.

My invention relates to fire-place heaters and ventilating-fines; and it consists in afire place formed of horizontal sections of bqnt clay made in semicircular iorm, and having a tongueand-grooved joint, and alsoa combined chimney and ventilating-flue rising from the fire-place to the top of the house, made up of horizontal tongued and grooved section of circular form, of burnt clay, having peculiarlyconstructed ventilating hot-air chambers, as

In the drawings, A B G D, &c., represent the fire-place, of which A is the base-plate, having detachable plate A, of semicircular form, constituting the hearth of the fire-place. On this base-plate is a semicircular flange or tongue, a, which enters a semicircular groove in the under side of a semicircular burnt-clay section, B. The upper edge of this section isalso provided with a corresponding flange or edge of the next semicircular section, 0, and this latter has at its upper edge a tongue or flange, c, that enters a groove in the under side of the section D, and so on throughout the sections E and F. There may be a greater or less number of these sections, dependent upon the height of the fire-place or the vertical depth of the sections, and all of said sec tions are made hollow, forming non-conducting air-spaces, as shown.

I is an inner lining, of brick or fire-tile. G is the top plate, of conical form. In the middle of this top plate there is an opening, d, for the escape of the smoke, and around this there rises a flanged ring, d, upon which sets the lowest of the chimney-sections, H. These chimney-sections are in the nature of hollowrlngs with a central opening forming the smoke-flue, and an annular chamber, e,which 5o chambers are open at the bottom and fit over and inclose the flanges or tongues f of the subjacent sections, and are closed at the top with the exception of a series of holes, 9, which open through the tongues or flanges from one annular chamber to the next above. One of the'chimney-sections, H, on each floor above the first is provided with a nipple, F, which communicates with the inner or smoke flue, and which nipple provides means for using a stove on any of thefloors above. On each floor, also, one or more of the chimney-seetions is provided with holes h, opening into the room, for ventilating purposes. As the chimney becomes hot a draft of air is intro- 65,

duced through these holes into the annular chambers of the flue-sections, and passes up through the holes in the flanges or tongues to the top of the chimney, where it passes into the upper section, J, of the chimney, which has no annular chamber, but has a detachable top, K. At the point where the thimbles in the sections H of the flue are located there is a sheet-iron casing, H forming an airspace to protect thewalls from the heat of the 7 thimble.

I am aware that it is not new to construct a chimney of burnt-clay sections having an inner smoke-fine and an annular air-flue, and I do not claim this, broadly.

Having thus described my invention, what I claim as new is 1. A fire-place composed of hollow horizontal sections of material of semicircular form, connected detachably by tongue-and-grooved 8 5 joints, substantially as shown and described.

2. A fire-place composed of a base-plate, A, with flange a and detachable plate A, and a top plate, G, with subjaeent groove and two or more semicircular sections, B 0, made 0 hollow to form air-spaces, and connected by tongue-and-groove joints to form the walls of the fire-place, substantially as shown and described. I 1

8. The chimney composed of sections H, 5 formed with a central opening and an annular chamber open at the bottom and provided with perforated flanges f at the top, adapted to enter and fitted into the open bottoms of lining, I, the converging cap-plate G, and the the annular chambers, leaving a smooth conchimney composed of sections H, constructed tinuous central opening, substantially as and snbstantially as shown and described.

for the purpose described. THEODORE O. NATIVEL. 5 4. The combinationof the hollow semieir- \Vitnesses:
