FIREPLACE.

SPECIFICATION forming part of Letters Patent No. 549,823, dated November 12, 1895. Application filed August 28, 1894:. serial No. 521,533. (No model.) Patented in England August 12, 1893,110. 15,353.

- editor, a subject of the Queen of Great Britain, residing at London, England, have invented certain new and useful Improvements in Fireplaces, (for which I have obtained a patent in GreatBritain, No. 15,353, bearing date Au-- gust 12, 1893,) of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a vertical transverse section, and Fig. 2 a horizontal section on the line a: a, Fig. 1, showing my hot hearth applied to a fireplace in such a manner that it forms the bottom of the grate thereof. 7 Fig. 3 is a trans verse section illustrating another form or modification of my said invention. Fig. 4 is a front elevation of part of the hot hearth shown in Fig. 3. Fig. 5 is a transverse section illustrating a further modification of my invention, and Fig. 6 is a similar View showing a still further modification thereof.

Like letters indicate corresponding parts throughout the accompanying drawings.

The object of my invention is to provide for the better utilization of the heat from fires in fireplaces in such a manner as to effect economy in the consumption of fuel therein, While obviating the necessity for the use of a fender. I accomplish this result by providing a device which I term a combined hot hearth and fender.

This device consists, essentially, of an inner hearth fitting into the fireplace-recess and adapted .to support the fuel and an outer hearth which extends to a suitable distance in front of the grate or of the chimneypiece and conveys the heat of the fire into the room, and which may also serve, if desired, in place of a fender. The said inner and outer hearths are formed of a single piece of cast metal or other suitable material, or they are made of two or more pieces fitted or joined together in any convenient manner. The outer hearth is in some instances provided around its outer edge with a fender-curb of any desired section or design.

My improved device can be made of various sizes and shapes to suit any fireplace, and it may have a monogram, crest, coat-of-arms, or otherornament formed on or secured to its front or outer part.

\Vhen a fire is burning in a fireplace pro vided with my combined hot hearth and fender, the heat transmitted to the inner hearth from the fire is conducted to the outer hearth and thereby radiated into the room. Any available part of the hearth can, moreover, be used for cooking or for other heating purposes.

The hot hearth is preferably arranged at a higher level than the. floor of the room to more efiectually insure an adequate supply of air tothe fire and to permit the utilization of the under side of and the space beneath the said hot hearth for heating purposes. The air-space beneath the hot hearth is in some instances left open in the front and at the sides. In other instances it is inclosed by means of a metal plate or in any other convenient manner.

If desired, I provide a door or doors to permit access to the space thus inclosed, in which case the said space can be utilized as an oven or hot chamber for cooking or for warming or keeping warm plates, dishes, or other articles.

In thearrangement shown in Figs. 1. and 2 the hot hearth a is made hollow and is support-ed beneath the grate Gb y means of brickwork b, (orby beingletinto the wall or in any other convenient manner,) the front or' outer part of the said hearth being provided with suitable legs 0 for supporting it. The said hearth is shown with a fender-curb at around the edge of its front or outer part. This fendercurb may, however, be dispensed with, if desired. It will be seen that the front or outer part of the hot hearth, whether made with or without the curb, serves very efficiently in place of a fender. Moreover, not only does it conduct the heat from the fire and radiate it into the room, but the air circulating around and beneath it, and also through it, if desired, becomes warmed and thus the apartment can in a short space of time be brought to the desired temperature and can be maintained at a uniform temperature more easily than heretofore and with a comparatively-small consumption of fuel. Thehot hearth can also be conveniently used for warming the feet, by resting the feet thereon, or for drying boots, socks, and other articles upon or in the space beneath the same. Kettles and other cooking utensils or other articles 7 can also be placed upon the hot hearth for the purpose of warmin g them or keeping them warm, or for cookin g food or boiling water.

I sometimes form on the hot hearth a projections or ribs 0, which extend upward there from into the grate G and facilitate the transmission of heat from the fire to the said hot hearth.

In the arrangement shown in Fig. the SllilCObOllOZttll the hot hearth is completely inclosed by means of a metal or other plate a extending around the front; and sides of the said hot hearth and secured thereto by rivets or otherwise. ()no or more doors a", Fig. 4, may, if desired, be providedin the metal plate (1 to permitaecess to the said space.

According to another modification of my invention, I construct myhot hearthas shown, for example, in Fig. 5, so that it can be used with a curb-Iemler f or a tender of any other suitable description.

According to a further modification of my said invention 1 provide for causing air from the exterior of the building to pass through the space beneath the hot hearth and then through a pipe or passage behind or at either or both sides of the fire into a recess or cavity in the front of the fireplace above the fire, iro m which recess or cavity the air previously heated in its passage beneath the hot hearth and through the aforesaid pipe is discharged in a series 01 jets or in the form of a thin sheet or layerfor example, through a slit or slits between the brickwork of the chimney and the metal plate supporting the same. By this means I am enabled to promote the draft and to cure smoky chimneys. For this purpose I inelose the space beneath the hot hearth and suitably connect the said space with a pipe, passage, or tunnel extending to the exterior of the house or other building and with another pipe or passage extending behind or at one side of the fire and communicating with the aforesaid recess or cavity in front of and above the fire. The heated air is drawn upward through the said passages, the cold air irom the outside of the house or other lmilding entering the space beneath the hot hearth and gettin \Yfllfll'lOtl. on its way. I have shown an arrangement of this kind in Fig. 0. The air is conveyed from the exterior of the building through 'a pipe 1 into the space inclosed by the hothearth (I/ and passes thence through a pipe or pipes h at the side or sides of the fire into a recess or cavity j in the brickwork above the fireplace. From this recess or cavity the heated air is discharged through the slit or opening 7c in such a manner that; it will mix with the gaseous products of comlnistion rising from the fuel in the grate.

It is evident that the construction and arrangement of my combined hot hearth. and. fender may, if desired, be somewhat modified without departing from the nature of my said invention and that the said combined hot hearth and fender may be used in combination with fireplaces wherein gas or oil or other heating medium, such as electricity, is used instead of coal or other solid fuel.

\Vhat I claim is 1. The combination with a fire place, of a plate of heat-conducting material arranged. in said. fire place and elevated above the fire place bottom to form an air space beneath the plate, said plate forming the bottom of a grate and extending to a suitable distance in front of the fire place, and a fire-grate super imposed upon the rear upper portion of said plate, substantially as described.

The combination with a fire place, of a plate of heat conducting material arranged in said place and elevated above the fire place bottom to form an air space beneath the plate, said plate forming the bottom of a grate and extending to a suitable distance in front of the fire place, a wall or casing around the front and sides of said space, and a fire grate superimposed upon the rear upper portion of said plate, substantially as described.
