FURNACE.
Specification of Letters Patent.
Application filed February 19, 1913.
Paton ted Dec. 16, 1913.
Serial No. 749,422.
To all whom '57 may concern lie it known that I, ALBERT MT. Joy, a
citizen of the United States of America, re-
siding at Greeni'sburg, in the county of lVestmoreland and State of Pennsylvania, have invented certain no if and useful improvements in Furnaces, of which the fol lowing is a specification, reference being had therein to the accompanying drawing.
This invention relates to fin-naces, and more particularly to that type of furnace commonly styled a hot-air heater.
The primary object of my invention is to furnish a furnace of the above type with a novel heat retainer through which cold air passes and is heated prior to being dis-- tributed to the z partmcnts of a building, the construction of the heat retainer being such that cold air is heated for a period of time after the fire of the furnace has gone out or been extinguished.
Another object of this invention is to furnish a furnace with a novel heat retainer and baffle plate that insures cold air being thoroughly heated and raised to a comfortable temperature before escapingthrough the fines of a furnace to the apartments of a building.
it further object of this invention is to provide a hot air heater consisting of comparatively few parts that are inexpensive to manufacture, durable, easy to assemble, and highly eflicient for the purposes for which they are intended. v
ll ith the above and other objects in view the invention resides in the novel construc tion, combination and arrangement of parts to be hereinafter specifically described and then claimed.
Reference will now be had to the drawing, wherein Figure 1 is a vertical sectional view of a furnace in accordance with this invention, Fig. 2 a plan of the same, Fig. 3 is a horizontal sectional view of a furnace illustrating a baffle plate, and Fig. lis a similar view of a furnace illustrating a heat retainer.
A furnace in accordance with this invention comprises a cylindrical shell or casing 1 having a bottom plate 2 and a top plate 3.
lVithin the shell 1 there is a closed hollow element constituting a fire box or chamber 4: having a vertical exhaust stack 5 extending through the top plate 3 of the shell 1. Within the fire box l there is a conventional form of grate 6 upon which fuel can he placed through the medium of a connection 7 between the fire box and the shell 1, said connection being ordinarily closed by a door 8. i-inother connection 9 between the bottom of the fire box 4 and the shell 1 permits of ashes being removed from beneath the grate and this coi'incction is normally closed by a door 10.
Limited within the shell 1 and resting upon the breast of the fire box 4 is a heat retainer 11 having a plurality of vertical openings 12 that are disposed in radial rows, as shown in Fig. l. The heat retainer 11 is made of a porous material, as fire clay, and said heat retainer absorbs and holds in suspension heat from the fire box f, whereby cold air admitted to the shell 1 through an inlet connection 13 is heated as it passes upwardly through the openings 12.
Located above the heat retainer and also above the lire box and surrounding the stack 5, is a hot air divider which consists of a horizontal plate 141- providcd with a plurality of vertical lines 15 which aline with the lines connections 16 carried by the top 3 of the shell. The function of the hot air divider is to cause a more perfect circulation and so divide the hot air as to distribute equally to the fines. The line connections 16 are in communication with diverging fines l7, employed for distributing heated air to the apartments of a building.
I attach considerable importance to the heat retainer ll, particularly when made of tire clay, as it a well known fact that this product of nature possesses a heat retaining quality that is sufficient to disseminate heat even after the source of heat is extinguished. It is also essential to use the baffle plate l l above the heat retainer whereby air will be retarded in its upward movement and heated by the upper surface of the heat retainer. The retarded air can only escape through the lines 15 directly into the flue connections 16 and consequently is not exposed to the upper walls of the shell 1 to that extent that the heated air would be reduced in temperature before escaping" to the apartments.
It is thought that the operation and utility of a furnace in accordance with this invention will be apparent without further description and while in the drawing there is illustrated a preferred embodiment of the invention it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.
hat 1 claim is l. A furnace comprising a shell provided with a top and a cold air inlet, a closed hollow heat retaining element arranged within the said casing and constituting a firebox, an exhaust stack opening into the top of the said element and projecting through the top of the casing a horizontally disposed heat retainer arranged within the casing and surrounding and supported by the upper portion of said hollow retainer said heat retainer provided with vertical openings, a hot air divider consisting of a plate surrounding said stack and arranged above said heat retainer and provided with vertical flues, flue connections carried by said top and alining with said vertical flues, and means whereby access can be had to said fire-boX.
2. A furnace comprising a shell provided with a top plate and a cold air inlet, a closed hollow element arranged within the said casing, an exhaust stack opening into the top of said hollow element and projecting through the top of the casing, a horizontally disposed heat retainer arranged within the casing and surrounding and supported by the upper portion of said hollow element, said retainer provided with Vertical openings, a hot air divider consisting of a plate surrounding said stack and arranged above said heat retaining element and provided with vertical flues, flue connections carried by. said top and alining with said vertical fiues, and means whereby access can be had to said fire-box, said heat retainer being of greater thickness than said plate.
In testimony whereof I affix my signature in the presence of two witnesses.
ALBERT MT. JOY.
