UNITED STATES OLAF N. DYBVIG, OF
DET ROIT, MICHIGAN.
summon Application flled July 6,
The present invention relates to household heating furnaces and more especially to furnaces of the hot air type. 4
' Among the objects of the invention is to 5v increase the efficiency of the heat exchange between the combustion chamber and gases and the air to be heated.
Another object is the provision of a cheaper and more eflicient and more easily in constructedand installed radiating element fora furnace of this type.'
Other objects will be readily seen by those skilled in the art upon reference to the following description and drawings, in
which Fig. 1 is a vertical section with partsin Fig. 3 is a detail view partly in section? and partly in elevation of one of the connecting members.
As indicated in the drawings, the furnaceconsists of a central combustion chamber 10 preferably of sheet metal and closed at the to with a cap 11 which may be riveted or we ded-"in place. This chamber 10 is mounted upon a base member 12 in a suban stantially air-tight manner, preferably by placing the lower edge of chamber 10 in a groove in the top of the base member 12;
In the drawings, the combustion chamber is shown as having therein an oil burner 15 5 built according to the description set forth in my application for'Letters Patent of the United States, Serial Number 108,509, filed May 12, 1926, but it should be noted that the features of the present invention are not limited to oil burning furnaces but may be utilized in urnaces adapted for the combustion of tidal or other fuel.
Near theiiitop of the chamber 10 there is a' flue 16 leading therefromto a ring-shaped 5 radiator 20, and direct-1y opposite the connec- 'tion between the flue and the radiator is a,
ameter than the chamber 10 and is locatedconcentricall therewith near the top ofthe chamber. *T is radiator 20 is connected on the side opposite the flue 16 by means of a connecting member 21,- more specifically 1926. Serial No. 120,627.
centric with the chamber 10 and is connected to radiator 22 by aneans of a connecting member ea e ness similar to the connectlng member 1. The radiator 24 is connected through a third connecting member 25, similar to the other two, to a'lower radiator 26 which is of substantially the same size as radiator This lower radiator 26 is connected through a flue 30 to the stack 18, as indicated, and the draftfor the furnace is controlled by a damper 31 in the stack.
About the lower end of chamber 10 there is preferably a cylindrical sheet metal shield 35 spaced from the chamber and concentric therewith and with the radiator 26. The purpose of this shield 35fis to prevent the radiation of heat from the lower part of the combustion-chamber to the radiator 26, as will be more fully set out later.
The assembly of the chamber 10, base 12 and radiators 20, 22, 24, and 26 is enclosed within a suitable outer casing 40 having air inlets 41 and outlet conduits for heated'air 42 leading to the parts of the building to be heated, and suitable means, not shown, will be provided for supplying air and con-- firolling the draft to the combustion cham- The several radiators and connecting members are preferably formed of. sheet metal and each radiator is preferably made in four parts. Two of these parts will be semi eirc'ularf channel-shaped members curved inwardly and the other two parts .will be semi-circular channel-shaped members curved outwardl'yand mating with the first two members to form substantially complete circular conduits. These mating membars will be provided with flanges and the flanges crimped together to form a substantially air-tight joint. A conduitwill be so formedjas to be substantially oval in cross section, that is, one in which the vertical axis will be uite substantially lon er than the horizonta axis, as indicated in t e drawings. A conduit formed in this shape conforms more nearly to the stream-line of the rising air in casing 40 and therefore permits the air to contact with the outer surface of the radiator much more effectively than if the latter were circular in section.
The connecting members 21 will be, formed of two halves in the same fashion as the radiator and may have the flue ends so arranged as either to enter the half radiators 20, 22, etc., or tohave the ends of the radiators enter the connecting member. In the and the air passing over the outside.
By means.of the dampers. 19 and 3l the' flow of combustion gases through the sev-- eral radiators may be very easily and efliciently regulated so that the gases passing out of stack 18 may be cooled almost to ordinary atmospheric temperature. This arrangement allows a very efiieient combustion of the fuel used.
Having now described the invention and the preferred form of embodiment thereof, it is to be understood that the said invention is not to be limited to the s )ecifie details of construction herein shown ut only by the scope of the claims which follow.
1 claim 1. A heating furnace consisting of a com- -bustion chamber, a casing enclosing said chamber and spaced therefrom, a vertical series of horizontally arranged sheet metal radiating fiues disposed in the said space in staggered relation, and a heat shield disposed between the lower part of the combustion chamber and the lowermost flue.
2. In a hot air heating furnzue, a combustion chamber, a plurality of radiating fiues connected thereto and arranged horizontally and in vertical series relation whereby theair to be heated and the combustion gases. may be conducted in counter- .current'relation, and means for preventing re-heating of the coolest combustion gases by radiation from the combustion chamber.
