We, JOHN GEORGE CHAMBERLAIN and RALPH PLAYER, trading as Joseph Wright
& Co, of Tipton, in the County of Stafford, and of 124, Victoria Street, in the
City of Westminster, Engineers, and JAMES RADCLIFFE, Engineer to the said
Joseph Wight and Company, do hereby declare the nature of this invention
to be as follows.-
This invention has for its object to provide means whereby grease is efficiently
emoved from exhaust steam, whether from high or low pressure cylinders
According to this invention the exhaust steam is passed into a chamber contain-
ing perforated tubes with a tube o rod inside each and preferably with slag
wool or fibrous material on like absorbent material in the spaces between the
perforated tubes and the internal tubes on rods the said spaces opening into a
vessel beneath into which the grease intercepted 18 received. The apparatus is
preferably arranged as follows -In one part of an upper chamber are arranged
the perforated tubes and internal tubes oi 1ods aforesaid, the internal tubes, or
1ods being passed at the upper ends, through holes in the top of the chamber
and secured in such a manner that they can be readily withdiawn for cleaning
or other purpose such as the renewal of the material in the spaces between them
and the outer perforated tubes The said spaces communicate by openings in the
bottom of the upper chamber with a grease chamber beneath
The other por-
tion of the said upper chamber is provided with a deflector which descends at an
angle from the exhaust steam inlet to near the level of the lower ends of the per-
forated tubes The bottom of this portion of the upper chamber is perforated
and communicates with a grease chamber beneath The steam outlet from the
upper chamber is beyond the said perforated tubes so that the exhaust steam in
passing through the apparatus first impinges against the deflector and grease 18
intercepted and passes, through the perforations in the bottom of the part of the
The
upper chamber beneath the said deflector into the grease chamber beneath
steam then passes under the said deflector and amongst the perforated tubes on
its way to the outlet, it, in its passage, having the remaining grease separated
from it by the grease being carried by the steam through the perforations in the
tubes into the spaces between them and the inner tubes or 1ods and being taken
up in the said spaces (the material in the said spaces facilitating the absorption
of the grease) the said grease passing therefiom into the grease chamber beneath.
Each such giease chamber is preferably provided with draw-off pipes and cocks
by which grease and deposit from each grease chamber can be discharged at
intervals into a general grease chamber beneath

We, JOHN GEORGE CHAMBERLAIN and RALPH PLAYER, trading as Joseph Wight
& Co, of Tipton, in the County of Stafford, and of 124, Victoria Stiert, in the
City of Westminster, Engineers, and JAMES RADCLIFFE, Engineer, to the said
Joseph Wight & Company, 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. -
This invention has for its object to provide means whereby grease is efficiently
removed from exhaust steam, whether from high, on low, pressure engines.
According to this invention the exhaust steam is passed into a chamber contain-
ing perforated tubes with a tube, or 1od, inside each, and preferably with slag
wool, or fibrous material, or like absorbent material, in the spaces between the
pertolated tubes and the internal tubes, or rods, the said spaces opening into
a vessel beneath into which the grease intercepted is received
We will describe an aliangement according to this invention with reference
to the accompanying diawings Figure 1 being a vertical section and Figure 2 a
halt plan and half horizontal section on the line 1, 2, Fig. 1 In one part of an
uppei chamber à are aanged the perforated tubes B, and internal tubes, or
rods, b
The tubes B are secured to head pieces bs, by pins, 01 11vets, as shewn,
or otherwise, and the tubes o1 10ds, b, can be secured in the said head pieces by
screwing, as shewn, so that the tubes or 10ds 6 can be readily withdrawn for
cleaning, or other purpose, such as the renewal of the absorbent material in the
spaces between them and the outer perforated tubes This material is shewn
at 63, as being wrapped round the tubes, or 1ods, b The said spaces between the
tubes B, and the rods, or tubes, b, communicate by openings in the bottom of the
chamber A, with a grease chamber C beneath. The other portion of the said
chamber A, 18 provided with a deflector plate a³, which descends at an angle
before the exhaust steam inlet a, as shewn, near to, or towards, the bottom of the
chamber A The bottom of this portion of the upper chamber is perforated as
shewn at a and communicates with a grease chamber C beneath The steam
outlet a from the chamber A is beyond the said perforated tubes B, so that the
exhaust steam, in passing through the apparatus, hist impinges against the
deflector plate a³, and grease is intercepted and passes, through the perforations a³,
in the bottom of the part of the chamber A beneath the said deflector, into the
grease chamber C³ beneath The steam then passes under the said deflector plate aª
and amongst the perforated tubes B, on its way to the outlet at, it, in its pas-
Bage having the remaining grease separated from it by the grease being carried
by the steam through the perforations in the tubes B, into the spaces between
them and the inner tubes, oi rods, b, the said gicase being taken up in the said
spaces, (the material in the said spaces facilitating the absorption of the grease),
and the said grease passing therefiom into the grease chamber C beneath
grease chamber C, C is provided with openings c, &, by which grease and deposit
from each grease chamber pass into a general grease chamber 1 beneath, or there
may be, in place of these openings c, &, draw off pipes and valves by which the
grease and deposit can be diawn at intervals from the chambers C, C², into the
chamber D. c, d, are hand holes (provided with suitable covers) for cleaning
purposes.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
olaim 18:-
1 In apparatus for removing grease from exhaust steam, a steam chamber
having perforated tubes and inside them, rubes or rods the perforations in the
first named tubes being in communication with the steam chamber and the open
ends of the said tubes being in communication with a grease chamber beneath,
substantially as herein before described
2. In apparatus for removing grease from exhaust steam, a steam chamber
having perforated tubes with tubes, or 1ods, and absorbent material inside them,
the perforations in the first named tubes being in communication with the steam
chamber, and the open ends of the said tubes being in communication with a
grease chamber beneath; substantially as hereinbefore described
3 In apparatus for removing grease from exhaust steam, the combination of a
steam chamber having perforated tubes and tubes, or 1ods, inside them, as claimed
by the preceding claiming clauses and between these and the steam inlet a deflect-
ing plate with perforations in the chamber beneath and grease receptacles beneath
the tubes and perforations substantially as hereinbefore described and illustrated
in the accompanying drawings
4 A filtering apparatus for separating grease from exhaust steam, the said
apparatus being constructed, or arranged, substantially as hereinbefore described
