Petroleum Burning Furnace.
We, WILLIAM TYLER CHAMBERLAIN of 85 Spruce Street, Norwich,
Connecticut, United States of America, 'Engineer, and CALVIN BOLLES BEEBE
of 41, Elisabeth Street, Norwich, Connecticut, United States of America..
Gentleman, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in cand
by the following. statement:-
This invention has particular relation to the feeding and distribution of oil in
petroleum burning furnaces; the immediate purpose of this invention being to
provide specially for the free commingling of oil,. air and steam as the said
elements pass into the combustion chamber.
In order to explain said invention clearly the annexed sheet of drawings has been
provided in which Figure 1' is a side elevation of a locomotive boiler embodying
said invention and Figure 2 shows' portions of the front and rear of such a boiler
in central vertical section.
Figure 3 is a cross sectional view on line X of Figure 1 and Figure 4 is au
enlarged, central, sectional view of one of the air and steam pipes m and their
supports. In Figure 5 are illustrated (considerably enlarged) the inner or delivery
end of one of the several hollow stay bolts which are utilized as oil pipes.
The said invention is here illustrated as applied to a locomotive boiler but it
will be obvious that it is as well adapted for use with other forms of boilers.
In the annexed drawings the letter a indicates the shell of a tubular boiler,
b. the tubes, c the stack and d'the fire box or 'combustion chamber, said chamber
being provided with a door e through which the fire may be viewed when desired.
The casing d' of the combustion chamber is supported chiefly by a number of
stay bolts that are made hollow and extend outward, beyond the boiler shell a,"
and the outer ends of said hollow bolts are connected by pipes 9 that are in turn
connected with a main supply pipe h that leads from an oil tank located at some
convenient place as, for example, on the locomotive tender.
The supply-pipe h is provided with a valve h¹ by means of which the flow of oil
through said pipe may be regulated or cut off entirely..
Immediately beneath the combustion chamber d is a chamber i that is connected
by a number of hollow stay bolts (f) with the said combustion chamber and,
leading from the steam dome to said chamber i is a pipe k by means of which
super-heated steam may be carried into said chamber to find its way thence
through pipes into the combustion chamber.
Within, and concentric with, said pipes are smaller pipes m that extend from
the upper ends of pipes f downward to and through the lower wall of the steam-
chamber i thus providing a number of passages through which air may pass freely
into the combustion chamber.
It will now be seen that three distinct systems of pipes lead into the combustion
chamber, to wit, one system for oil, one for air and one for jets of steam and these,
to produce the best results, should all be arranged and regulated to discharge the
said elements into the combustion chamber in proper proportions to provide, when
commingled; an inflammable gas. In order to prevent the too free discharge of
oil through the pipes f the inner ends of said pipes are preferably covered with
wire gauze, of very fine mesh, which, as the oil is forced through the pipes 9 and f.
under low pressure, causes said oil both to spray into the chamber d and to run

page_text: down the walls thereof in very thin sheets and so long as the oil mingles with the
steam, which enters through pipes f, a fierce and constant heat is maintained in
the said combustion chamber, and this desirable result is reached without the aid
of a stoker, as will be understood. Pipe k is provided with a valve k' by means of
which the supply and pressure of steam in chamber may, be, regulated and said
chamber i is provided with a petcock by means of which water (resulting from
condensation, or otherwise) in said chamber i may be drawn or blown out.
A proper degree of draft may be maintained in the combustion chamber by any
of the means in common use.
The described arrangement of oil, steam and air pipes provides a practical and
economical means for mingling the several elements and makes it possible, for the
engine driver to also control the fire and with a system, as herein set forth,,
whereby perfect combustion may be assured, an 'oil burning furnace may be made
more economical than a coal burner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
'In combination with a boiler, a combustion chamber supported within said
boiler by hollow stay bolts whose outer ends are connected with an oil supply pipe,
a steam chamber, pipes connecting the steam and combustion chambers, and air
supply pipes leading through the said steam pipes, as set forth and discharging at
the delivery ends of the steam pipes.
