S. WHITMARSH. Heating Stove.

Patented Aug. 17, 1852.

SAMUEL WHITMARSH, OF NORTHAMPTON, MASSACHUSETTS.

CALORIFERE.

Specification of Letters Patent No. 9,206, dated August 17, 1852. i

To all whom it may concern Be it known that I, SAMUEL WHITMZARSH, of Northampton, in the county of Hampshire and State of Massachusetts, have invented a new and useful Improvement in Caloriferes, Stoves, or Furnaces for Warming Buildings; and I do hereby declare that the same is fully described in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of the said drawings Figure 1 denotes a top view, Fig. 2 a front elevation, Fig. 3 a central and vertical section of a stove or calorifere made on my improved plan. Fig. l is a horizontal section of it taken through the radiator. Fig. 5 is a horizontal section taken through the water vessel and the ash it. p In Fig. 3 of the said drawings A represents a furnace or chamber for combustion of fuel, B is the grate thereof, C the opening or passage for supplying the chamber with fuel, D is the ash pit.

Above and out of the top of the chamber A, I carry a vertical pipe E, which by a partition F, I separate into an ascending and descending smoke flue, the pipe being covered on its top as seen at a. The partition F is not carried up to the top or cover a of the pipe E, but terminates at a short distance therefrom so as to allow the smoke and.

volatile products of combustion to pass over it and down the passage 0, such passage being made to communicate with a discharge pipe G.

The entire fire chamber A or any suitable part thereof I inclose in a bed of sand H, H, or other suitable absorbent non-combustible matter, which I place within a case I made to surround the fire chamber in whole or part as circumstances may require. Beneath the bed of sand I make a reservoir or chamber K for containing water, the sand being made to rest on the top (Z of such chamber K which should be perforated with numerous fine holes. The top of this reser voir has a tube e extending above it through which water may be poured to supply the vessel is and made to rise above the top surface of the top (Z of it in order that it may be absorbed into the mass of sand by the capillary attraction of the same. The sand chamber I open into a steam tight radiator L made in any suitable manner so as to expose a large external surface to the atmosphere.

In the drawings it is represented as consisting of fourteen metallic chambers f, f, f, &c., made to radiate from and open into a central chamber 9 that surrounds the pipe E. The inner end of each chamber f, f, is open from its top to its bottom, so as to allow a free passage for vapor in the chamber g to enter the chamber f.

The furnace or chamber of combustion may be constructed of metal or other suitable material.

The operation ofthe stove or calorifere is as follows. The sand will absorb water and become saturated with it so as to cause the external surface of the furnace or chamber A to be surrounded by or in-contact with a mass of wet sand. The fuel in combustion will heat the sand so as to cause vapor to form in it and pass upward and into the radiator where the heat of such vapor will be abstracted to such extent as to cause the vapor to condense into water and in such state run back into the sand where it will be again heated, vaporized and made to pass into the radiators. By employing a mass of wet sand around the furnace and a condensing radiator it will generally be impossble to elevate the Water of the sand to a boiling temperature or one calculated to produce steam of any injurious pressure. The sand absorbs the heat of the furnace and retains I it for a great length of time, while it also absorbs and vaporizes and reabsorbs and revaporizes the water. The mass of sand once saturated with water will require but very little added to it from time to time to provide for the small by leakage from any cause The condensing radiator may also be filled with sand if desirable, but I generally prefer to confine the sand to the chamber around the furnace.

The air of the apartment in which the stove may be will be warmed by contact with the external sides of the sand chamber quantity that may be lost 7 and those of the radiator, and with great" economy of fuel and withoutdanger of any elevation of temperature of the water in the sand to any dangerous extent.

My improvement or principle may be ap plied to hot air furnaces for heating several apartments of a building, also to stoves for culinary purposes.

What- I claim as my invention is- The combination of the Water supply reservoir, the chamber or bed of sand,'and a furnace or chamber of combustion,

In testimony whereof I have hereto set the Whole 5 being made to operatesubstantially as specio my signature, this nineteenth day of March SAMUEL WHITMABSH. it
