COMPLETE SPECIFICATION.
Regenerative Heating Furnaces.
I, ALEXANDER YOUNGER, Rolling Mill Foreman, of 1289 Harvard Street, in the
City of Cleveland, in the County of Cuyahoga, in the State of Ohio, United States
of America, do hereby declare the nature of my invention for REGENERATIVE
HEATING FURNACES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of my invention is to construct an improved form of regenerative heating
furnace, in which natural gas and Archer fuel gas and other similar kinds of fuel may
be economically utilized.
The points of invention are: A gas pocket located intermediate of the regenerator
and bridge wall and provided with ports connecting respectively with the regenerator
and opening toward the bridge wall whereby a portion of the current of air, may be
induced to pass through the gas pocket in finely divided streams, that it may the
better and more perfectly commingle with the gas; and the pocket discharging
toward the bridge wall through a series of ports that open toward the bridge wall,
causes the gases to mingle with the heated air that has not passed through the pocket,
and to meet at the contracted neck of the furnace where perfect combustion is
assured, again when the direction of the current is reversed a portion of the
products of combustion passes, through the pocket and highly heats the same,
thereby raising the temperature of the gas issuing from the pocket when the
current is again reversed. This heating of the pockets is a direct aid to economy
and smokelessness. In the ordinary sized furnace I contract the lateral width of
the pocket whereby 1 compel the heated air and gas that may pass through the
pocket to more intimately and thoroughly mingle and coalesce.
Referring to the drawings: Figure 1 is a vertical sectional view taken on the
dotted line y y of figure 3 and in the direction indicated by the arrow: :.figure 2
is a horizontal sectional view of the furnace taken on the dotted line x x of
figure 3; figure 3 is a vertical section of the furnace taken on the dotted line z z
of figure 1, the right hand portion of the view representing a portion of the furnace
in elevation.
The central or metal heating portion of the furnace being of the usual form no
description of the same is here necessary, and as the two end portions containing
the regenerators are duplicates of each other, it is not thought necessary to show
in the drawings or describe in the specification more than one of them. So too,
it has been deemed best to omit all description of the flues leading to and from
the chimney and the reversing valve that changes the direction of the current as
any suitable flue and valve may be used.
A is the lower or primary regenerator composed of reticulated brick-work or
checker-work, a portion of it being located directly under the upper or secondary
regenerator B, a flue 6 leads upwardly and discharges into the said upper

page_text: regenerator B, that is composed also of reticulated brick-work having the usual
flues that discharge into the horizontal flues C. The bottoms of these flues C are
substantially on a level with the top d of the bridge wall D.
Intermediate of the regenerator and the bridge wall and located below the secondary
regenerator and also below the level of the top of the bridge well, is the inclosed gas
pocket E that extends transversely of the furnace and is provided with the ports F
that connect with said regenerator and open into the ports of the same, said pocket
is also provided with ports G that open toward the bridge wall and discharge directly
into the contracted neck H of the furnace that is formed by the upward projection
of the bridge wall. In the usual size of furnace, which is the size shown in the
drawings filed herewith, I preferably make the gas pocket of less width than the width
of the furnace proper and thereby as the air and other gases pass through the pocket
they are contracted laterally; and while passing through the neck of the furnace they
are contracted vertically, whereby a better and more complete mingling and coalescing
of the gases is produced than as if they were spread out in a broad passage. Again,
by means of the regenerator with its checker work, the air passing through the same
is divided into thin streams before it is brought into contact with the gas in the gas
pocket and this also aids in the more complete mingling of the gases and helps
combustion. A portion of the hot air issuing from the regenerator passes through
the pocket and there a primary mingling of the air and gas takes place, then as the
gas issues from the pocket it meets the streams of air about to pass the bridge wall
and a secondary and final intermingling takes place and perfect combustion is assured.
It will be noticed that no matter in which direction the current is passing a portion
of the same passes through the gas pocket and thus the pocket becomes as intensely
heated as the regenerator, which is a great aid in the economical, complete and
perfect combustion of the fuel.
The air issuing into the lower regenerator A passes upwardly through the: flue b
and into the regenerator B, thence downwardly into the ports where it divides, a
part passing into the pocket E through ports F and a part passing out of the end of
the said flues C where it is met by the gas issuing from the pocket through the
ports G. When the valve is reversed the products of combustion pass over the bridge
wall, and then a part passes through the ports G into and through the pocket, which
is thus highly heated. The remainder passes through the ports C where it ismet
by the gases that have passed through the pocket and up out of the ports F, thence
the whole body of gases passes upwards through the regenerator B and thence through
regenerator A.
The foregoing description and accompanying drawings set forth in detail, mechanism
embodying my invention; change may be made therein provided the principles of
construction respectively recited in the following claims are employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what
I claim is :
1. In a regenerative heating furnace, the combination with a regenerator, and a
heating chamber, of an inclosedigas pocket provided with independent ports respectively
connecting with said regenerator and heating chamber, whereby a.
portion of the
heated. gases issuing from said regenerator is caused to pass through said inclosed gas
pocket, substantially as set forth.
2. In a regenerative heating furnace, the combination with a regenerator and
a heating chamber, of an inclosed gas pocket located intermediately. of the two
and provided with openings located in different walls of said pocket and respectively
connecting with said regenerator and heating chamber, substantially as set forth.
3. In a regenerative heating furnace, the combination of a regenerator; a.bridge
wall projecting into the neck of the furnace and thereby contracting the same, and
an inclosed gas pocket provided with a series of ports respectively connecting with
said gas pocket and furnace neck,-an. opening also. connecting said regenerator and
neck independently, whereby a portion of the heated gases issuing from the regenerator

page_text: passes through the said gas pocket and another portion passes directly to the bridge
wall, substantially as set forth.
4. In a regenerative heating furnace, the combination with an inclosed gas pocket,
of a primary and secondary regenerator having flue connection with each other, said
secondary regenerator provided with a series of flues opening directly into the neck
of the furnace, and also provided with a series of ports opening directly into said
gas pocket, said pocket provided with a series of ports opening directly into the neck
of the furnace, whereby the body of gases issuing from the regenerator is divided,
a part passing directly to the furnace neck, another part passing through the gas
pocket and thence to the furnace neck where they mingle with the former portion,
substantially as set forth.
5. In a regenerative heating furnace, the combination of a regenerator, a bridge
wall projecting into and contracting the neck of the furnace, and a gas pocket
extending transversely of the furnace and provided with ports connecting, respectively
with the said regenerator and opening toward the said bridge wall, said gas pocket
of less width than the body of the furnace whereby the gases passing through the
same are contracted laterally, substantially as set forth.
