Specification Accepted, 18th May, 1888
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 :-
The object of my invention is to produce a separator for extracting grease, grit
and water from exhaust steam as it passes from the engine through the exhaust pipe,
and in which the products of condensation grease and grit are automatically carried
off by a drip pipe; and the invention consists in certain details of construction as
hereinafter fully described and set forth in the claims.
Referring to the accompanying drawings:-
Figure 1, represents a side view of an automatic grease, grit and water separator
embodying my invention.
Figure 2, is a vertical longitudinal section of the same.
Figure 3, is a view of one of the upright perforated plates detached.
Figure 4, is a view of the bottom perforated plate detached.
Figure 5, is a vertical longitudinal section through a separator embodying mix
invention with a modified arrangement for operating the valve.
Figure 6, is a plan or top view of the bucket and lever.
Figure 7, is a vertical section through a separator with the catch plates arrangea
horizontally.
A, represents the body of the separator, and B, a receiver for the grease, grit and
water that is separated from the exhaust steam; the body A, is provided with suitable
Hanges to connect. it to the exhaust pipe C, as shown.
In the body A, are secured a series of plates D, D, these plates are provided with
a number of small holes d, d around each of which, on the side nearest the engine,
s a small lip or flange e. The holes in one plate are so arranged as not to come

page_text: opposite the holes in the next plate thereby preventing any steam from passing
through without first coming into contact with one or more of the plates.
area
The combined area of the small holes in each plate must not be less than the
of the exhaust pipe, and 1 prefer to make it somewhat greater so as not to impede
the passage of the steam. The plates are capable of being adjusted nearer to or
further from each other so as to regulate the expansion of the exhaust steam passing
through and between them, the space between the plates being regulated by short
pieces of pipe ff placed upon the bolts g that secure the plates together. The central
plate is provided at the top and on each side with a boss or enlargement which is
screw threaded to receive screws h, that secures the plates in the body A.
The receiver B, is secured to the body A, by bolts j, j and is provided with a cap
or cover B at its lower end; near the upper end of the receiver is provided a per-
forated plate E, which rests upon a small ledge & formed in the receiver; the object
of this plate is to prevent the steam passing into the receiver in a volume.
F, is a hollow float or ball connected by a hollow stem G, to a puppet valve H,
provided with a hole through its centre so that the products of condensation in the
float will be carried off, thereby preventing the float from bursting.
A curved plate E' is interposed between the perforated plate E, and the plate F, to
prevent the pressure of the steam affecting the action of the float.
The seat I, of the valve is formed of metal or other suitable material which rests
upon a bushing J, in which the lower part of the valve works. To the upper part of
the float F, is secured a short rod K, that has a bearing in a boss formed on the
perforated plate E, so as to guide the valve when the float rises or falls.
By having the seat I, of the valve H, of metal, the valve will not be injured nor
prevented from closing should any grit lodge upon the seat.
To the cap or cover B₁, is secured a drip pipe L. On one or both sides of the
receiver B, is secured a sight glass M, so that the float and the contents of the receiver
can be seen when desired.
The exhaust steam passing in the direction of the arrows comes into contact with
the first series of plates D, except such portions as may pass directly through the
holes d in the said plate which steam will impinge against the second plate of the
series. The steam coming into contact with the plates causes any grease, grit, or
water that may be in the steam to become deposited upon the faco of the plates which
deposits then run down the plates and through the perforated plate E, into the
receiver B, the said deposits being prevented from running through the holes d by
reason of the flanges e.
When the receiver becomes sufficiently full the float F, rises, opening the valve H,
thus allowing the contents of the receiver B, to escape into the drip pipe L, until
sufficient of the fluid has escaped, when the valve again closes thereby preventing all
escape of steam.
Should the plates D, become damaged or worn out they can be readily removed
so that a new one or set may be inserted by simply removing the receiver B, and
taking out the screw h.
In the arrangement shown in Fig. 5, all the parts above the perforated plate E,
are as before described, but instead of the ball float F, I employ a bucket F¹, supported
on the end of a forked lever G, fulcrumed on a spindle g, secured in bearings in a
projection cast in one with the receiver B, and to the spindle g, outside the projection
on the receiver, is secured a bar provided with a weight at its outer end to counter
balance the weight of the bucket F, and on the end of the spindle g is secured
a short lever m which is connected to the stem of the valve H, by a rod or cord n.
A plate E¹ provided with a single hole in the centre is cast in one with or secured
to and immediately below the perforated plate E, so as to deliver the grease, grit
and condensed water into the centre of the bucket E'.
The operation of this arrangement is as follows: The bucket becoming filled with
the grease, grit and condensed water taken from the exhaust steain over-flows into
the receiver B; and as that becomes filled the bucket floats, which when raised_
sufficiently opens the valve H, and allows the contents of the receiver to escape

page_text: when the bucket again falls and the valve is closed when the operation is again
repeated.
This arrangement is particularly applicable for high pressure while that described
with reference to Figs. 1 and 2 is particularly applicable for low pressure.
:
In Fig. 7, I have shown the catch plates arranged horizontally in this case I
make the plates D, dish shaped, and provide each with a teat or nozzle d', to conduct
the
grease and such like down the centre into a pipe A¹ to conduct it to the
receiver B, constructed as described with reference to Figs. 1 and 2.
To keep the plates the required distance apart I have shown them provided with
short legs which take the place of the spacer tubes used with vertical plates.
Of course either of the receivers may be employed with either the vertical or hori-
zontal plates as may be required according to the place in which the separator is
to be employed.
In cases where it is required to use more than one separator they may all be
connected by suitable pipes to one receiver B.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent I declare that what I claim is
1. A grease, grit, and water separator consisting of a body provided with removable
perforated plates and a receiver provided with an automatic discharge valve,
substantially as set forth.
2. The body A, provided with perforated plates D, in combination with the
receiver B, provided with a valve H, operated by a float, substantially as set forth.
3. The body A, perforated plates D, pipes bolts g and screws h, in combination
with the receiver B, and cover B', the perforated plates E, valve H, rod G, and
float F, substantially as and for the purposes set forth.
