IMPROVEMENT IN HEATING APPARATUS.
Specification forming part of Letters Patent No. B929559, dated July 3, 1877; application filed August 4, 1876.
To all whom it may concern:
Be it known that I, WmLrAM BLIss, of Ashleyville, in the county of Hampden and State of Massachusetts, have invented a new and useful High-Pressure Hot-Air Heating Apparatus for cities or villages, which invention is fully set forth in the following specilication and accompanying drawings.
My invention consists in a combination of devices whereby air can be forced through a heating-furnace, and thence through a series of airmains or distributing-pipes laid under ground a-nd in buildings, in order to conduct said heated air through all the streets of a village or city, for use in manufacturing or mechanical industries, and to serve in dwelling-houses for warming and culinary purposes.
My invention is primarily based upon the Well-known principle that air compressed to a certain degree of density is a better conveyer of heat, retaining caloric better, than that under the opposite conditions.
To make my plan operative for the purposes above named it is necessary to heat the air to be distributed to a high degree.
Having forced the air through a proper heating-furnace, with the requisite devices to give the air the desired density and heat, and consequent distributing-force, it next becomes necessary to provide suitable main and branch pipes for conducting it to the places of consumption, that shall prevent the loss of heat, to any great degree, by radiation or contact with the ground. e
Under certain conditions, or for special purposes, air may be required possessing a greater degree of heat than may be obtaina-` ble from that in the mains at points remote from the main furnace, and to provide for such a contingency I place reheating-furnaces wherever upon the line of the mains it may be found necessary for the above purpose.
For convenience in laying the air-mains, and to insure more perfect joints therein, a non -condncting material, which is placed around the air-main, and held in its place by an outer sheath concentric with the main, is placed in the annular space, between the main pipe and the sheath, after the mains are laid and to render this operation convenient, the
sheath is constructed with a longitudinal opening ou one side throughout its length, or nearly so, and said opening is bordered by anges, in which suitable covers slide for the purpose of closing such openings.
For the purposes of obtaining the requisite density in the circulating heated air in the distributing-mains, and to`insure an ample delivery of air through them, I employ airpumps, placed near the heating furnace, which force the air through the furnace, and thence through the mains, said air-pumps to be run either by steam or Water power, as may be most convenient.
To obtain steam-power in the most economical Way for running the air-pumps by a steam-engine, I set a steam-boiler on the top of the furnace, which heats the hot-air pipes so that heat in passing from the furnace to the chimney will pass through the lines of the boiler, and generate steam therein.
In completing the details of this `circulating system of hot air under pressure, I shall place safety-valves at such points on the line ofthe air-mainsV as may be found necessary to prevent an undue pressure upon the pipes. I shall also employ'stop gates or valves ou the mains, such as are usually placed on the lines of gas or water mains.`
' Having explained the object of my invention, and the functions of the various devices which I propose to employ to render it operative and. useful, I would now still-further explain some of its peculiarly novel features.
I am aware that hot air can be conducted through pipes in buildings upwardly, and, to a limited extent, horizontally by its rarelication by heat, and consequent tendency to rise to higher points; and I am also aware that a certain degree of force may be imparted to a current of heated air by a fan, used to drive the air with more force than it attains by its rarelication, or to more remote parts of a building than it could' be made to reach were it not so propelled; but it is neither of these results that I seek to obtain by my devices, and such means as would accomplish those results successfully would be inoperative in supplying heated air under the conditions and for the purposes demanded by my plan.
I do not propose to blow hot air into rooms in a house for the purpose of warming them, but to circulate hot air, under pressure, through pipes and radiators, for warming buildings, substantially as steam is circulated for the same purpose.
I propose also to furnish hot air for industrial purposes, under such a degree of pressure that fans and bellows may be dispensed with in iron-founderies and smiths shops, and
the air be delivered for such use heated to so great a degree as to materially reduce the consumption of fuel usually required for` such purposes.
So also for culinary purposes, I propose to furnish hot air for cooking, conducted .from the mains by proper pipes to the kitchen, in substantially the same manner as steam is conducted for similar purposes.
The advantages of hot air circulated for warmingand cooking purposes, as specied, over a steam circulation for thesame objects, are obvious. In a systemof air circulation no trouble can arise from thevconsequences of condensation, while with steam, that would be an item of serious cost in installation, and a never-ending source of trouble from choking of drips and freezing. Also, the cost of fuel for generating the steam would be much the non-conductingsubstance with which I Y surround my pipes making this high degree of heat safe and practicable.
My furnace is constructed with one or more fire-boxes, and with double walls entirely surrounding that portionof it designed for heating the air-pipes, leaving a spacebetween said double walls sufficiently large to place airrounding the re box or boxes is perforated so as to admit heat from the re or fires freely into the space between the walls where" the .above-mentioned air-pipes are placed.
ply power for running myv air-pumps-is generated in the boiler before alluded to, and'which is placed over the furnace. The heat from the re below under the air-pipes is generally sufcient for this purpose, but to guard against contingencies I- build anauxiliary fire-box in the end of the furnace, by -which additional heat to that derived from the source above mentioned may bel obtained.
Referring to the drawing, Figure 1, Sheet l, is a plane view of the furnace, air-heating pipes, and air-pumps, and a portion of the distributing-mains. Fig. 2, Sheet`2, is a ver-A tical sectional elevation of the furnace, airheating pipes, air-pumps, and steam-boiler. Fig. 3, Sheet 2, is a view in section of the hotair-distr-ibuting main, itsv sheath, and a connecting-pipe or branch connection. Fig. 4, Sheet 2, is a vlongitudinal view of the hot air main, showing its sheath and slides, and a connecting-nut. Fig. 5, Sheet-3, is a` vertical sectional view of the furnace, air-pumps, airheating pipes,and steam-boiler, showing the perforated lining in the furnace between the lire-space and the space in the furnace walls which inclose the air-heating pipes.
