JAMES A. DONNELLY, OF BROOKLYN, NEXV YORK.
HOT-WATER HEATING SYSTEM.
SPECIFICATION forming part of Letters Patent No. 710,566, dated October 7, 1902. Application filed May 28, 1901, Serial No. 62,201. (No model.)
To all whont it may concern:
Be itknown that I, J AMES A. DONNELLY, of the borough of Brooklyn, Kings county, New York, have invented an Improvement in HotlVater Heating Systems, of which the following is a specification.
My invention relates to hot-water heating systems; and it consists of the improvements which are fully set forth in the following specification and are shown in the accompanying drawing.
More particularly, my invention relates to that class of hot-water heating systems in which the water is heated by the circulation of steam through the body of water which is circulated through the radiators. In systems of this kind, in which the water is heated in a tank or reservoir from which the radiators are supplied by a system of circulating-pipes, it is usually necessary, if the system is extensive, to employ alarge heater or condenser, and much heat is lost by radiation through the supply-pipes before the water reaches the radiators. To overcome this difficulty, it has been proposed to employ a system of steamheating pipes extending through each radiator or through a tank or reservoir connected therewith; but such an arrangement requires an extensive system of steam circulating pipes and the circulation of the steam is attended with the usual difficulties of extensive steam-heating systems.
It is the object of my invention to utilize steam for the purpose of heating the water in such a way that the water will be heated to a maximum temperature adjacent to the point at which the radiator is located, so that it may enter the radiator without material loss of heat and that the heating of the water may be effected without the use of an extensive and complicated system of steam-heat: ing pipes.
In carrying out my invention I employ a hot-water main extending through the building in combination with a steam heating-pipe extending through said main to heat the water therein throughout its length and a series of independent hot-water circulating and radiating systems located in different parts of the building and communicating directly with the hot-water main. By this means I am able to maintain a substantially maximum temperature in the water throughout the hot water main and to supply this water at maximum temperature directly to the radiators without the necessity of circulating it through any supply-pipes.
The drawing shows a diagrammatic view of a hot-water heating system embodying my invention.
A is a hot-water-supply main or riser extending up through the building, and while shown as a single vertical pipeit may have branches or extensions leading to different portions of the building. Extending through this water main or riser is a steam-heating pipe 13, receiving steam from any source through the supply-pipe O and returning the water of condensation through the usual return D, which may lead to a tank or receiver or may be connected with an exhausting apparatus or vacuum pump to operate the steam circulating apparatus as a vacuum system.
E represents hot-water radiators or coils located at the various points in the building where radiation is to be effected and connected by the usual supply and return pipes F G with the hot-water main A.
H is a valved discharge-pipe from the hotwater main,by which the main may be drained when desired, and I is the'supply-pipe for filling the main.
N is an air-vent to relieve the return-pipe D of air.
Steam is circulated through the steam-pipe B and heats the water in the main A. The hot water passes from the main through the pipes F to the radiators or coils E and the colder water returns to the main through the pipes G. The radiators E and their connections F G constitute independent hot-water circulating and radiating systems, which are located in the various parts of the building where radiation is desired, and these independent circulating and radiating sytems communicate with the common hotwater main A, in which the water is heated by the steam-pipeB. Eachindependentcirculating and radiating system may embrace a number of radiators or coils.
If desired, an automatic or thermostatic valve J may be employed in the return-pipe, which maybe connected with a vacuum-pump or exhauster to draw out the air and Water of condensation.
In the construction shown I have arranged this automatic valve J in a valved by-pass K, leading around the valve L in the return D. By operating the valve M in the by-pass and the valve L in the return the automatic valve may be introduced into the return or cutout, as may be desired.
I do not mean to limit myself to the details of construction shown, as they may be varied Without departing from my invention.
What I claim as new, and desire to secure by Letters Patent, is as follows:
1. A hot-water heating system for buildings consisting of a hot-water riser extending through the building from floor to fioor and constituting a hot-Water main, a series of independent hot-water circulating systems communicating with said riser at different points in its length and embracing hot-water radiating apparatus, and a steam heating-pipe eX- tending longitudinally through said hot-water riser from floor to floor to heat the water in said riser and cause it to circulate through said series of independent hot-water circulating systems.
2. A hot-water heating system for buildings consisting of a hot-Water riser extending through the building from floor to floor and constituting a hot-water main, a series of independenthot-Watercirculating systems communicating with said riser at different points in its length and embracing hot-water radiating apparatus, and a steam heating-pipe extending longitudinally through said hot-water riser from floor to floor to heat the Water in said riser and cause it to circulate through said series of independent hot-water circulating systems, a return leading from said steam pipe and an automatic valve in said return.
3. A hot-Water heating system for buildings consisting of a hot-water riser extending through the building from floor to floor and constituting a hot-water main, a series of independent hot-water circulating systems communicating with said riser at different points in its length and embracing hot-water radiating apparatus, and asteam heating-pipe extending longitudinally through said hot-water riser from floor to floor to heat the water in said riser and cause it to circulate through said series of independent hot-water circulating systems, a return leading from said steampipe, a valve in said return, a by pass or branch about said valve, and an automatic valve located in said by-pass.
In testimony of which invention I have hereunto set my hand.
