IMPROVEMENT IN STEAM-BEATLES.

TO `AL L WHOM IT MAY CONCERN:

Be it known that we, EDWARD B. CLARK, JosIAn S. CLARK, and WILLIAM S. CLARK, all of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Steam-Heating Apparatus, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying drawing, which makes part of this specification, and which represents a vertical'section through our improved heating apparatus, as applied to an ordinary chamber-stove.

-It is the object of our invention to combine with an ordinary stove or with a range a steam-heating apparatus, so that -while deriving the requisite heat from the stove or range in the room in which it is placed we may utilize the same heat by making it generate steam, which is conducted to any other part of the building where it-may be required. To these ends our invention consists inarranging a coil of steam pipes Within the fIrechamber of a stove,l range,por furnace, and connecting them `directly with the water-supplg1 in such a manner as to generate steam without the use ot' a boiler, and to conduct the steam thus generated through suitable pipes to the apartment to be warmed by it; an automatic stop-valve being so arranged'in the water-supply pipe as to keep the water at a uniform height in the fire-chamber, to prevent the burning of the pipes, and yet to supply water as fast Vas it is 'vaporited Our invention further consiste in a novel arrangement of the pipes in the tirecharnber. 4Our invention further consists in a novel method of balancing the steam pressure on the supplyv valve so as'to leave its motions uncontrolled .save by the pressure of the supply water.

-To carry out the objects of our invention, we convey the water from a street main, hydrant, or fronr'a tank, A, (situated in any convenient location,) through a feed pipe, B, into a water-drum, C, provided with a floatvalve, D, which prevents the water from rising above the proper water. line d. A water pipe, E, leads from the bottom of the drum C into an ordinary cylinder-stove, E', to the upper portion of which it ascends in a spiral coil, F. It is then bent down within the coil into a U shape, and up again to the top of the stove, (to increase the surface exposed to heat,) whence it leads ofll to a coil of pipes, G, whichv may bev situated in the same room with the stove, or may be in another apartment, orin any place where it is desired. The exit pipe H is provided Vwith an escape pipo, J, in which is a safety-valve, I, leading intov the'stove pipe K to prevent the pressure from vbecoming dangerously high. A pressure pipe, L, likewise leads from the upper part of .the water-drum Cl to the coil F, thus balancing the pressure on thc float-valve D, and enabling it to risc and fall freely with every change of the water level.

'The operation of this apparatus is. very simple, and it can be adapted to the ordinary stoves and rangos usod in every building at small cost. The fuel required to heat a room or to cook a meal will suiiice also to generate steam enough to warm another room, and the regulation of the supply of Water by the quantity of steam used secures the utmost economy in every respect. It requires no attention beyond that involved in keeping up an ordinary tire. It is manifest .that this apparatus can be used for heating several rooms or an entire building without any other change than an increase in the quantity of fuel used, and the consequent more rapid generation of steam.' The direct :application of the heat to the pipes, by passing the pipes through the iirc and-generating the steam within the stove itself, renders this apparatus so compact that it can be placed in any room without obstructing the ordinary uses of the apartment, or occupying any space that thc stove itself wouldnot require or render unavailable for other purposes, as the drum and connections could be placed between the stove and the wall, directly under the stove pipe.

What wo claim as ourinvention, and desire to secure by Letters Patent, is 1. The combination, substantially in the manner described, with an ordinary stove for warming buildings, of' a Coil of steam pipes provided with an automatic feed-valve which supplies water as fast as evaporated, thus maintaining the water at a uniform level, preventing the burning of the pipe, and dispensing with an external steam-drum. y

2. The combination, substantially as described, ofthe water-drum and iloat-valve,'with the heatingcoil and balancing pressure pipes, for the purpose of preventing pressure on the valve.

In testimony whereof we have hereunto subscribed our names.
