STEAM-HEATER.

No. 7,152. Reissuea May 30,1876.

N,FETERS, PHOTO-LVIHOGRAPHRR, WASHINGTONy D Cy Speciication'forming.part of Letters P To all whom t't may concern Be it known that I, ANDREW VAN HORN, of Brooklyn, in the county of Kings and State of New York, have invented a new Improvement in Steam-Heaters 5 and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a vertical central section, and in Fig. 2 a horizontal section in the plane m w, Fig. l.

This invention relates to that class of steamheaters in` which the steam is conducted from the generator to the radiators distant from the generator.

The invention consists, principally, in a generating-coil surrounding the tire-box, and a secondary or steam coil yabove the tire-box, and connected with theV generating-coil, combined with a water-supply tank connected to said generating-coil, and with an exit from the steam-coil, to allow the steam to flow to the radiating' apparatus, and a return to the water-supply tank, all as more fully hereinafter described.

In the drawing, the letter A designates a furnace, which contains a secondary coil, B, one or more. This generating-coil is situated above the fire-grate O, and close to this grate, over the ash-box l) of the furnace, is situated .the generating-coil E. This generating-coil connects at its lower or oilter end, by means of a pipe, a, with a supply-tank, F, situatedoutside of the furnace, and the upper or inner end of said generating-coil connectsv by a pipe, b', with the lower end of the secondary coil B, said pipe b being situated outside the furnace A. The steam which is generated passes through a pipe, c, to the heating-pipes, and from the pipe c extends a branch pipe, d, to the supply-tank. The pipes c and d are provided with stop-cocks e and f, respectively. The tail end g of the heating-pipes connects with the upper part ot the supply-tank, and this tank is filled with water to such a height ,are closed, and the UNITED STATES PATENT OFFICE.

IMPROVEMENT IN STEAM-HEATERS.

ter. The tail-pipe g is provided with a stopcock, h.

When a fire is kindled in the furnace, the water contained in the coil is rapidly formed into steam. It' the stop-cock e is opened, and the stop-cock f in the branch pipe d is closed, the steam generated passes through the heating-pipes, and finally back into the supplytank, and as the pressure in the supply-tank is thus made equal to that in the coils, the water from the supply-tank continues to pass through the generating-coil to the secondary coil, and a constant circulation is el'eeted. At the same time the water on passing is heated, and rapidly transformed into steam, and thereby an even and uniform' circulation is produced, and a regular supply ot' steam is obtained, and at the same time the generating-coil is protected against being' burned or overheated.

When it is desired to shut oft' the steam from the heating-pipes the stop-cocks e and h stop-cockfis opened. The steam generated is then conducted back in the supply-tank through the bran ch pipe d, and the circulation of water through the coils continues without interruption, so that said coils are not liable to become overheated.

My heater is applicable for railroad-cars, and also for buildings.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a steam-heater, the combination, with the steam-generating coil E and water-supply tank F, oi' the brauch pipe d, having stop-cock f, and steam-pipe o, having stop-cock e, substantially as and for the purpose described.

2. The combination, in a steam-heater, of the generating-coil E, the secondary or steam coil B above the generating-coil, and connected thereto, the water-supply tank F, connected to said generating-coil,4 and an exit for the steam from the secondary coil, to convey the steam to the radiating apparatus, and a return to the watertank, substantially as specified.
