CONSTRUCTION OF STOVESAND EIREPLAQES.

Specification of Letters Patent No. 806, dated June 23, 1838.-

To all whom it may concern.

Be it known that I, J osErH HURD, junior, of Stoneham, county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in the Construction of Fireplaces and Stoves for Cooking. or other Purposes tolVhich the Same May be Applied.

This improvement, the principle thereof.

and mode in which I have contemplated the application of that principle or character by which it may be distinguished from other inventions; together with such parts, improvements or combinations which I claim as my invention, I have set forth and described in the following specification and accompanying drawings referred to herein.

The general features of my improvement consist in such an arrangement of the oven, boiling apparatus, fireplace and flues, that the operations of baking, boiling and steaming, may be carried on at one and the same time by the same fire, or separately, when ever occasion may require. By so doing I economize heat, or in other words create a great saving of fuel.

The particulars of my said invention and improvement are represented by Plates 1, 2, a

A, A, A, is the brickwork surrounding and sustaining the oven and fireplace with the grate. This may be constructed as shown in the drawings, or otherwise built up as circumstances may require.

B represents a sliding box, having a grate in its bottom to sustain the coals. This box rests and can be pushed in, or drawn out upon a horizontal shelf or plate of iron A. The plate a has a square hole of suflicient size formedtherein, over which the box B may be placed, so that the ashes from the grate may fall through the same into the ash box 0.

D, is a small cylindrical boiler of iron or other suitable metal, placed in the upper part of the fireplace, and having its ends secured in brickwork. Near each extremity of the boiler D, a pipe I), b, is inserted and passes up and is properly connected'with a steam vessel E, E. The boiler D has two cocks 0 cl inserted in one of its ends, for the purpose of ascertaining the quantity of water or steam therein whenever necessary.

F, is an oven directly over the fireplace, the sides ofwhich are formed of metallic tubes 6, e, e, which pass through the top f,

and bottom g, serving as somany 'flues for the passage of the smoke and heated air from the fireplace, and thus expose a large heated surface to the air in the oven. Between the plate f, which forms theupper part of the oven, and the plate h, which serves to support the steam vesselsbE, E,is

another plate 71 hlavinga square j japerture near its center. As the smokepasses up the tubes 6, c, itimpinges against the underside of theplate i and is reflected; against the top f of the oven and passes. through the aperture in the plate 2" into the chimney where it escapes into theatmosphere.

7c, is a damper or flue valve, in the back of the fireplace, which on being opened, ad-

mits the smoke and heated air to pass di-- Z is another the oven, which on being opened suffers the vapor formed during the process of baking, to escape into the chimney, so that when U the lower damper is closed, the smoke rises through the pipe 6, e, and passes into the chimney through the aperture in the damper m. These dampers may be opened at pleasure, by means of the bent rods n 0 p proceeding therefrom.

G, H, I, are doors to the oven, fire place and 'ashpit.

By means of the sliding furnace, to be used in connection with the oven, the fire may be placed within a few inches of the bottom of the boiler, or the oven, or in such situation as to produce the greatest effect. It may be withdrawn at pleasure to receive fuel, and also when the heat may be to powerful for the oven or boiler.

When the furnace is in place, the fire door is closed, which prevents any cold air gaining access to the coals except through the grate. The tubes 6, e, materially assist the draft, while from their situation, they also cause the hot air from the furnace to spread equally over the under surface of the oven before passing oft through them; The heat the tube which connects it with the boiler D, and rises through the other tube into the opposlte steam vessel, and as the water be? comes heated in the boiler it ascends into the steam vessel. Onopening the lower closely. fitted and formed, as to answer'the purpose of digesters for softening bones, or such otherpurposes to which the same may be applicable. The number of the tubes e 6, their size, together with the dimensions of the boiler and other parts of the apparatus may be varied at pleasure. Instead of the whole being set in brickwork, it may be surrounded'by a casing of sheet or cast iron, or other proper metal, this forming a stove which may be removed at pleasure.v

7 Having described such parts of my improvement as I believenew and useful I now setforth my claim as follows.

- 1. The combination of the tubular oven with the boiling and steaming apparatus and fireplace, arranged and acting together as I have'herein described.

2. I claim separately, an oven constructed with tubular flues passing through the same from bottom'to top,,and so situated that the smoke and heated air from the furnace shall pass through thesame on both sides, and impart heat to the interior of the oven.

In testimony that the above is a true specification of my invention and improvement I have hereto set my hand this first day of October in'the year'of our Lord, one thousand eight hundred and thirty seven.
