Improvements applicable to Oil Engines.
We, PETER PHILLIPS BEDSON, D.Sc., Professor of Chemistry, Durham
College of Science, Newcastle-on-Tyne, and JAMES CULLEN HAMILTON,
Chemical Engineer, Arnside, near Carnforth, do hereby declare the nature of
this invention to be as follows, that is to say :-
Our said invention has for its object to deal with the offensive gases and vapors
ordinarily discharged from oil.engines, and whilst preventing the contamination of
the atmosphere therewith, to secure such economical results as may be obtainable.
In carrying out our invention according to one modification, we bring the
exhaust gases and vapors into intimate contact 'first with water, and afterwards
with mineral or other suitable oil. The oil employed may be the same as that
used for actuating the engine, and may be used in the engine after acting on the
exhaust gases and vapors so as to utilise any combustible matters it may take up.
The exhaust gases and vapors may be treated with water and oil by being passed
through one or more chambers containing coke or other like material, or having
any suitable mechanical arrangements such as are in use for scrubbing or purifying
illuminating or other gases. The water used may be that employed for cooling
the cylinder of the engine either before or after acting on the exhaust gases and
vapors. The exhaust gases and vapors are by preference passed first through. oue
chamber in which they are treated with water, and afterwards through another or
other chambers in which they are treated with oil.
In a convenient arrangement of apparatus for treating the exhaust gases aud
vapors a chamber is provided with horizontal partitions with openings or spaces
alternately at opposite ends, one of the partitions being without such opening or
space so as to divide a lower compartment in which water is applied from an upper
one in which oil is applied. The horizontal partitions have low weirs across them,
and between these there are dipping partitions with their bottom edges serrated.
The exhaust gases and vapors are admitted at the bottom and after reaching
the complete horizontal partition pass through a by-pass pipe to the upper
compartment from the top of which the purified gas is discharged. The oil is
admitted at the top and after traversing over the horizontal partitions of the
upper compartment in directions opposite to those of the gases passes off through
a trap-bend pipe at the complete partition. The water is admitted at the top of
the lower compartment, and traversing the horizontal partitions oppositely to the
gases and vapors, passes off through a trap-bend pipe at the bottom.

We, PETER PHILLIPS BEDSON, D.Sc., Professor of Chemistry, Durham
College of Science, Newcastle-on-Tyne, and JAMES CULLEN HAMILTON,
Chemical Engineer, Arnside, near Carnforth, 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 and by the following statement, that is to say :-
Our said invention has for its object to deal with the offensive gases and vapors
ordinarily discharged from oil engines, and whilst preventing the contamination of
the atmosphere therewith, to secure such economical results as may be obtainable.
In carrying out our invention according to one modification we bring the exhaust
gases and vapors into intimate contact first with water, and afterwards with mineral
or other suitable oil. The oil employed may be the same as that used for actuating
the engine, and may be used in the engine after acting on the exhaust gases and
vapors so as to utilise any combustible matters it may take up. The exhaust
gases and vapors may be treated with water and oil by being passed through one
or more chambers containing coke or other like material, or having any suitable
mechanical arrangements such as are in use for scrubbing or purifying illuminating
or other gases.
The water used may be that employed for cooling the cylinder of
the engine either before or after acting on the exhaust gases and vapors. The
exhaust gases and vapors are by preference passed first through one or more
chambers in which they are treated with water, and afterwards through one or
more other chambers in which they are treated with oil.
And in order that our said invention and the manner of performing the same
may be properly understood, we hereunto append' a sheet of explanatory drawings,
to be hereinafter referred to, and showing two modifications of apparatus as made
with our improvements.
Figure, 1, of the drawings is a vertical section of one modification, and Figure, 2,
is another view of a part of the same.
Figure, 3, is a plan as with a cover removed and
Figure, 4, is a vertical section of another modification.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
In the modification of apparatus shown in Figures, 1, and 2, for treating the
exlianst gases and vapors, a casing or vessel of rectangular form and made in hori-
zontal sections which are bolted together is provided with horizontal partitions, A, B,
C, D, and E, with openings or spaces, G, H, J, and K, alternately at opposite
ends, one, C, of the partitions being without such opening or space, so as
to divide a lower compartment, L, in which water is applied, from an upper
one, M, in which oil is applied. The horizontal partitions, A, B, C, D, and E,
have low weirs, N, across them, and between these there are dipping partitions, P,
with their bottom edges made with serrations as shown in Figure, 2. The exhaust
gases and vapors are admitted at the bottom of the casing or vessel by means of
an inlet pipe, Q, with a downwardly curving mouth, which directs them against
water lying on the bottom of the compartment, L. Thereafter the gases and
vapors pass through the opening, G, and between the partitions, A, and B, over
the weirs, N, and under the serrated dipping partitions, P. They then pass
through the opening, H, and between the partitions, B, and C, and next proceed
by a by-pass pipe, R, to the upper compartment, M, and through the spaces
divided by the partitions, C, D, and E, fiually escaping through the pipe, S.
The water is admitted at the top of the lower compartment, L, through a
trap-bend pipe, L1, and traversing over the horizontal partitions, B, and A, oppositely
to the gases and vapors, passes off through a trap-bend pipe, L2, at the bottom.

page_text: The oil is admitted at the top of the upper compartment, M, through a trap bend
pipe, M 1, and after traversing over the horizontal partitions, E, D, and C, in
directions opposite to those of the gases, passes off through a trap-bend pipe, M 2.
In the modification shown in Figures, 3, and 4, a casing or vessel is employed
very similar to that of the first modification, and it is provided with similar
partitions, A, B, C, and D, which are made with annular openings, G, H, J, and K,
each formed with a lip or projection round its upper edges. These annular
openings, G, H, J, and K,, are covered by annular hoods, P 1, which act like the
dipping partitions, P, of the first modification, each being bolted to its partition
and having its hottom edges serrated. For the descent of the oil from the space
above the top horizontal partition, D, and from the space between the partitions, D,
and C, to the space between the partitions, C, and B, dipping pipes, T, are
provided having their lower ends sealed to prevent gas or vapor passing up
through them. The gases and vapors are admitted by the inlet pipe, Q, and
pass upwards through the annular opening, G, and being deflected by the hood, P 1,
pass through the washing liquid to the next higher annular opening, H. In each
space they pass in a similar manner proceeding through the annular openings, J, and K,
and finally through the pipe, S. The water is admitted below the complete
partition, B, by a trap-bend pipe, L 1, into the compartment, L, and passes into the
space within the annular hocd, P1. by a lateral opening, V, in the hood. It then
passes by a dipping pipe, T 1, similar to the dipping pipo, T, into the space below
the partition, A, from which it escapes by a trap-bend pipe, L2. The oil is
admitted above the partition, C, by a trap-bend pipe, M 1, and passes off by a
trap-hend pipe, M2. The top space to which oil is not supplied from outside, is
provided for the depositing from the gases or vapors of particles carried up by
them in mechanical suspension.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is —
The treating of the exhaust gases and vapors of oil engines by bringing them
into intimate contact first with water and afterwards with oil, or with oil ouly, for
the purposes herein before described, and by means of apparatus substantially such
as is hereinbefore described or referred to.
