APPARATUS FOR HEATING B UILDINGS.

SPECIFICATION forming part of Letters Patent No. 361,784, dated April 26, 1887. Application filed May Ti, 1886. Serial No. 202,384. (No model.)

To all whom it may concern:

Be it known that I, ISAAC W. RUsHMoRE, of Plainfield, in the county of Union and State of New Jersey, have invented an Improvement in Apparatus for Heating Buildings, of which the following is a specification.

Furnaces have been constructed with a coil or jacketthrough which water is caused to circulate by the action of the heat of the furnace, and'there have been radiating-coils within an air-chamber for heating the atmosphere, and such atmosphere has passed into the apartments or rooms through tubes or flues. In practice it is found that with heaters having an air-chamber and lateral air-pipes, whether a furnace alone is used or whether hot water or steam is used in such air chamber, in

cold weather the air in the lateral air-pipes .the tubes or flues that pass from the furnacechamber to the respective rooms, and at the same time to increase the radiating-surface of the hot-air pipes.

In the drawings, Figure 1 ma vertical section showing portions of the building and of the furnace and of the hot-air pipes or fines with my improvements applied thereto, and Fig. 2 is a cross-section of one of the hot-air flues.

The furnace A is of any suitable character, and within the same is by preference a coil of pipe, B; but a waterjacket might be used in place of a coil of pipe.

O is a coil of pipes through which the hot water is caused to circulate, and this coil is within the air-chamber H, to which the atmosphere is admitted through an opening, I, as usual, and from this air-chamber H the hotair pipes or fluesK pass to the different rooms or portions of the building to be heated.

As my improvements are available with any arrangement of hot-air pipes or fines it is unnecessary to describe these parts any more fully.

My present improvements are available with hot-air fines that pass off in any direction; but

the utility is more apparent in the fines that have but a slight inclination.

From the heating coils G, I pass along through the hot-air flues K the circulatingpipes L. These circulating-pipes are double in each flue and open into each other at the up per and outer ends, 4, and at the hot-air chamber the circulating-pipes L branch out from the coil-pipes O at different elevations, so that the hot water will pass off near the upper parts of the coil 0 through the circulating-pipes Land back again to the lower portions of the coilpipes 0, thereby insuring a rapidity of circulation of the hot water within the air pipes or fines K, so as to warm such air and promote the rapidity of circulation and cause such warm air to pass along the pipes, which are but slightly inclined, with greater rapidity than otherwise.

In all hot-watcr-circulating apparatus it is necessary to maintain the continuity of the column of water and to prevent the accumulation of steam or gases in the higher portions of the coils. YVith my present improvement any such accumulation of air or gases in the circulating-pipes L would effectually prevent the apparatus operating reliably. To avoid this difficulty I provide branch pipes 1?, ex

tending above the upper and outer ends, 4, of

the circulating-pipes L, and to these branch pipes P cocks may be applied for allowing the air to be blown offlperiodically; but as there is usually a water-cistern in an elevated position within the dwelling-house I prefer to make use of said cistern for maintaining the necessary water-supply to the heating apparatus, and for allowing the escape of air and gases, and for preventing the accumulation of steam-pressure. With this objectin view, the pipes P are continued upwardly until they reach the reservoir Q, and it is usually preferable to unite these branch pipes 1? into one pipe where it passes into the reservoir; and by, placing these pipes at an upward inclination any air or steam will pass off through the water of the reservoir.

It is often difficult to obtain the necessary supply of hot water in all parts of a building. I therefore make use of the pipes P for conveying hot water to any desired portion of the s semst rooms or building; but in order to be able to draw such hot water it is preferable to provide a'cock, S, in the pipe Pabove the cock T, from which the hot water is drawn, so that the water from the reservoir Q may pass down into the furnace-pipes through some other portions of the branch pipes to supply the place of the hot water that is drawn from one of the cocks T. It is to be understood that the cock S,

should be opened after the cook T has been closed. a

In some rooms in distant portions of dwelling-houses-such, for instance, as'bath-rooms or water-closets--difficulty arises in obtaining the necessary heat in cold weather. added to my aforesaid apparatus the radiating- I coil Mwithin one of the rooms, the same being a continuation from one of the circulatingpipes L, passing through one of the heating- 7 flues, in order that the'hot water may circulate I have i and steam and for supplying Water, substantially as set forth.

2. The combination, with the furnace and the air-chamber around the same, of the hotair flues passing off from such chamber, and hot-water-circulating pipes within such flues, a reservoir for supplying water, and a branch pipe to such reservoir from the upper and outer ends of the circulating-pipes, substantially as set forth.

3. The combination, with the furnace and air-chamber and the hot-air flues passing off laterally, of circulating hot-water pipes within the-hot-air flues, a coil within the furnace for heating the water, a reservoir, and a connec tion between the upper and outer parts of the circulating-pipes and the reservoir, substantially as set forth.

4. The furnace-coil for heating water, theair-chamber, and the hot-air flues passing off from the air-chamber, in combination with the hotwater-circulating pipes within the hot -air fines and connected to the coil, and

radiator-pipes connected to the outer ends of ISA AC W. RUSHM ORE.
