Abstract
_________________________________________________________________
16738.
[Class 46.] A filter for separating solid impurities from oil and c.
comprises a jacketed casing having ports 3, 4 for the inlet and outlet
of a heating or cooling medium and containing a plug 7 having ribs 8b,
Fig.
2, forming longitudinal channels 8 on its outer surface.
The plug is adapted to be reciprocated by hand against the pressure of
a spring 15, which may however be placed outside the casing as shown
in dotted lines, by a hollow rod 16.
The oil enters the casing by a port 5 and flows through the rod to
radial passages 20 by which it is distributed to alternate channels
from which it passes over the edges of the ribs, which are in close
proximity to the inside of the casing, into the adjacent channels and
thence through the annular passage between the rod and the spigot 21
on the casing cover to the outlet 6.
The impurities in the oil collect in the channels and are periodically
forced into the sump 9 by reciprocating the plug so as to shut off the
outlet 6 from the interior of the casing and reverse the oil flow in
the channels.
In the event of the channels becoming choked the oil passes through
the ball valve 14 directly to the outlet 6.
The channels may be tapered.
In a modification, a duplex apparatus is described.

I, DAVID MCCROR In 3 SHANNON, of 44, Longridge Road, Earls Court,
London, a British Subject, do hereby declare the nature of this
invention to be as follows:This invention relates to apparatus for
heating or cooling, and separating solid impurities from liquids, and
the chief object is to provide apparatus by means of which a rapid
transfer of heat from one fluid to another is effected; a further
object is to effect a cleansing of the fluid treated during its
transit throughf the apparatus; the invention will be described by way
of example as applied to the cooling of oil, for which it is
particularly adapted.
According to present practice, difficulty is experienced in obtaining
a rapid and efficient transfer of heat-particularly in the case of
oil, owing to the fact that the main body of the fluid-oil for
examplepassing through the apparatus cannot readily be brought into
contact with the cooling surface; with the result that, for a given
fall of temperature, the apparatus must be of comparatively large size
This difficulty is accentuated where the fluid to be dealt with is an
inefficient conductor of heat, and in the case of oil a fairly thick
coating is formed on the cooling surface, acting as an insulator which
renders it difficult to cool the oil not directly in contact with the
cooling surface.
According to the present invention the difficulties referred to are
overcome by causing the fluid to be brought into intimate contact with
the heat exchanging surface in the form of a film of determinable
thickness, according to the nature of the fluid to be treatedc and the
degree of heat exchange required This is accomplished by providing one
or more passagewa-ys of suitable shape and dimensions, and in its
passage from inlet to outlet, the finia flows or is forced over
obstructions, such for example as knife edges or other forms of walls
of grooves or channels, located comparatively close to the heat
exchanging surface.
In the following description, the part of the apparatus through which
the oil or the like to 'be cooled is passed will be lPrice 1 ice 4 S d
termed the cartridge and the part through which the cooling medium is
circulated 55 or on which the said medium acts, will be termed the
casing, which usually surrounds the cartridge.
According to one modification, the cooling medium which may be water
or 60 other fluid, is circulated through an annular space in a casing
(usually cylindrical) having a comparatively thin inner wall, a
suitable inlet and outlet being provided for the cooling medium It is
also 65 provided with an inlet and an outlet for the oil to be
treated, said inlet and outlet of course not being in communication
with the inlet and outlet for the cooling medium 70 The cartridge is
in the form of a hollow plug, the periphery of which is provided with
a series of reversely set grooves or channels, the edges of the walls
of which are almost but not quite in contact with 75 the interior wall
of the casing Each alternate groove or channel is reversely arranged,
one set being in communication with the oil inlet and the other set
being in communication with the oil outlet 80 The casing is usually
arranged vertically, the oil inlet being in the lower part, and the
casing below this inlet is arranged to form a sump or settling chamber
for dirt and other foreign matter, a 85 grating, or a plate with a
suitable opening) being provided below the oil inlet and above the
settling chamber, so as to prevent deposited matter from being again
mixed with the oil 90 The cartridge is hollow, with a closed lower
end, its lower part being provided with a housing adapted to contain a
nonreturn valve, preferably a ball valve, which automatically comes
into operation 95 in event of the cartridge becoming choked and so
ensures the continuous passage of oil from inlet to outlet in even't
of the cooler failing to function, a point of importance in the case
of oil circulation, t 1 o particularly in internal combustion engines
The cartridge is located in the casing by means of a central spring in
the base its upper end being provided with a central stem which is
mounted in a 105 fitting which carries the oil outlet and Pdeae 25, 1
' 7, l 17 -_=: 1 1 7,,4,'- i -11 closes the opening through which the
cartridge is introduced into the interior of the casing The stem is
provided with a valve which, when the stem is depressed , cuts off the
oil from the outlet, thus forming a very effective means of clearing
the cartridge should it become choked On depression of the stem, the
cartridge moves downwardly in the casing, against the pressure of the
central spring; while the stem is held depressed , the valve on the
stem closes the oil-outlet, thus causing a reverse flow of oil through
the grooves normally in communication with the outlet, the oil passes
thence in a reverse direction into the grooves in communication with
the oil in 16 t, th-us forcing any dirt or other foreign matter into
the sump in the lower part of the casing, where they are trapped, and
from which sump they are adapted to be removed through a suitable
opening normally closed by a plug or the like, which may be
conveniently extended inwardly to form 1 a locating spigot for the
spring vhich supports the cartridge.
Usually a few reciprocations of the stem, causing corresponding
movement of the cartridge in the casing, are sufficient to clear any
dirt which has collected in the grooves In order to ensure a rapid and
thorough cleaning of these grooves by the reverse flow, the casing and
cartridge may be slightly tapered, in which case the constiuetion of
the casing would be suitably modified.
When the stem is depressed to give the reverse flow, the oil outlet is
closed, and:as this is undesirable in some cases, I obviate this in a
further modification by m O forming the oil inlet and outlet in the
upper end of the apparatus, suitable ports and division walls being
provided so that the ail normally passes from the inlet to the
interior of the cartridge, being deflected iat the bottom into the
inlet grooves or channels by a series of radial holes or a plate in
spaced relationship with the bottom of the cartridge, the flow of oil
from inlet to outlet being as above described The steni is provided
with a piston valve, and passes through an inwardly extended boss in
the cover so as to leave 1 an annular clearance space pro vided with
a-port (or ports) so arranged gas thaf, when the stem is depressed ,
the i piston valve cuts off the cartridge from i the outlet and gives
the reverse flow tovlear the cartridge, at the same time perInitting
oil to pass directly from inlet to 6 outlet without passing through
the cartridge.
-I find that -by arranging both the oil inlet and outlet in the upper
part of the apparatus, the inlet is kept free from the possibility of
becoming choked by dirt M deposited in the sump.
A duplex arrangement may be provided by means of a pair of casings
each containing a cartridge In this case each cartridge is carried
from a stem on which 70 is mounted a piston working in an upward
extension of the casing, suitable twoway cotrol valves being provided
In this modification, the cartridge in operation is in its lowermost
position, the oil 75 passing from the inlet flowing to the underside
of the cartridge and thence to the outlet via the inlet and outlet
passageways In this arrangement, a second twoway valve is provided
which, on the oil 80 feeding valve being placed in communication with
a particular cartridge, allows oil to pass to -the upper side of the
piston -mounted on the cartridge steni, so depressing the cartridge
These valves are 85 preterably arranged on the same spindle, and, on
reversing the valves to bring the other cartridge into operation, the
spring acting on the cartridge which has been put out of action,
causes the cartridge to 90 rise (as the fluid pressure has been
removed from that piston), thus causing the cleansing action During
the upward inovemient of the cartridge, the piston displaces the oil
above it, which leaks off g 5 through suitable ports.
In a modification of this type, instead of providing the stems of the
cartridges with pistons operated through a two-way control valve, the
stems may extend 100 through the tops of the respective casings, and a
single two-way oil supply valve may be provided operated by an
oscillating handle: each easing is provided with a pivoted arm having
suitable abutments, 105 the arrangement being such that in the
operating position for each easing, the handle moves the arm into a
position in which it depresses the stem of that cartridge The
arrangement otherwise is 110 similar to that last described.
I have described the above modifications of my invention by way of
example, but obviously the constructional arrangeiiient a-d details
way be varied within 1 l Z wide limits to suit different requirements,
Conditions of working, and the fluids to he dealt with, and it is to
be understood that lt is applicable generally to the heating, 3 o 00

Improvements in Apparatus for Heating or Cooling, and Separating Solid
Impurities frlon Liquids.
1, DAVID MOCRORIE SHANNON, of 44, Longridge Road, Earls Court, London,
a British Subject, 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 relates to apparatus for heating or cooling and
separating solid io impurities from liquids, and the -hief object
thereof is to provide apparatus by means of which a rapid transfer of
heat from one, liquid to another is effected; the invention will be
described by way of example as applied to the cooling of oil, for
which it is particularly suitable.
According to present practice, difficulty is experienced in obtaining
a rapid and efficient transfer of heat, particularly in the ease of
oil, owing to the fact that the main body of the liquid-oil for
example -passing through the apparatus cannot be readily brought into
contact with the cooling surface; with the result that, for 2 f a
given fall of temperature of the oil, the apparatus must be of
comparatively large size This difficulty is accentuated where the
fluid to he dealt with is an inefficient conductor of heat, and in the
case of oil a fairly thick coating is formed on the cooling surface,
acting as an insulator which renders it difficult to cool the oil not
directly in contact with the cooling surface.
According to the present invention apparatus for heating or cooling
and separating solid impurities from liquids is tharaeterised by an
outer casing through which a heating or cooling agent flows and ran
inner member or cartridge provided with ribs the edges of which are in
close proximity to the inner surface of the casing so as to effect
filming of
therefrom.
the
liquid
over
said edges and separate the impurities
The invention will now be more fully explained hereinafter with
reference to the accompanying drawings which show:Fig 1 a vertical
section of a simple { O forn of construction of apparatus accordins to
the invention.
Fig 2 a part vertical section of a cartridge forming part of the
apparatus; Fig 3 a plan of a part of the cartridge j 5 Shown in Fig 2.
Fig 4 a similar view to Fig 2 of a edified eartridge; Fig 5 a duplex
form of apparatus, in vertical section.
In the following description the part of 60 the apparatus through
which the oil or other liquid to be cooled is passed will be termed
the cartridge and the part through which the cooling or heating medium
is circulated or on which the said cooling 65 or heating medium acts,
will be termed the casing, which -usually surrounds the cartridge.
According to one construction, the cooling medium, which may be water
or other 70 fluid, is circulated through the annular space 1, Fig 1,
of a easing 2 (usually cylindrical) having a suitably thin inner wall,
an inlet 3 and outlet 4 being provided for the cooling medium The
casing 2 is also provided with an inlet 5 and an outlet 6 for the oil
to be cooled or heated, said inlet and outlet of course not being in
communication with the inlet and outlet for the cooling or heating
medium 80 The cartridge is in the form of a hollow plug 7, the
periphery of which is provided with a series of longitudinal grooves
or channels 8, Sa, the edges of the walls 8 b of which are almost, but
not quite, in con 85 tact with the interior wall of the casing.
Each groove or channel 8, 8 a is closed at one end 8 and adjacent
grooves
or channels are reversely arranged, one set being in
communication with the oil inlet and 90 the other set being in
communication with the oil outlet.
The casing 2 is usually arranged vertically and I find that by
arranging both the oil inlet and outlet in the upper part 95 of the
apparatus, the inlet is kept free from the possibility of becoming
choked by dirt deposited in the sump The bottom of the casing 2 is
arranged to form 100 a sump or settling chamber 9 for dirt and other
foreign matter, a grating, or a plate with suitable openings 11 being
provided below the oil inlet and above the settling chamber so as to
prevent deposited 105 matter from being again mixed with the oil.
The cartridge 7 is hollow, with a closed lower end 12, its lower part
being prom vided with a housing 13 adapted to con 110 tain a
non-return valve 14, preferably a ball valve, which automatically
opens in the event of the cartridge becoming ehoked and so epsures the
continuous passage of oil from inlel; to outlet which 115 is of
importance in the ease of oil circula-tion particularly fil internal
conabustion 403,639 engines The cartridge is located in ti casing by
the terminal ends which f closely therein and is also held in plac by
means of a central spring 15 in tb base or the spring might be mounte
externally as at 15 a beneath the operatin handle, the cartridge being
provided wit. a central spindle or stem 16 which i mounted in a
fitting 17 which carries, o lo preferably connects with, the oil
outlet
-and closes the opening through which th cartridge is
introduced into the interio of the casing The stem or spindle 16 i
provided with a piston valve 18 which when the stem is depressed ,
cuts off the oil from the outlet 6, thus forming ia ver, effective
means of clearing the cartridg 4 -should it become choked On
depressioi of the stem 16 the cartridge 7 moves down.
2 o wardly in the casing 2 against the pres, sure of the central
spring 15 or 15 a while the stem 16 is being depressed thf -valve 18
on said stem closes the oil outlet, thus causing a reverse flow of oil
through the grooves normally in communication with the outlet 6, the
oil passing thence in a reverse direction into the grooves in
communication with the oil inlet 5 and thus forcing any dirt or
foreign matter into the sump 9 in the lower part of the casing 2 where
it is trapped and from which it can be removed through a suitable
opening normally -closed by a plug 19 or the like, which may be
conveniently extended inwardly to form a locating spigot as at 20 for
the spring supporting the cartridge 7, where such -spring is used.
Usually a few reciprocations of the o stem 16 causing corresponding
movement of the cartridge 7 in the casing 2 suffice to clear any dirt
which may have collected in the grooves 8, 8 a To ensure a rapid and
thorough cleaning of the said grooves 8, 8 a by the reverse flow The
reversely set grooves in the cartridge 7 may be slightly tapered,
being deeper at 8 c and 8 d while they may also be peripherally
tapered as shown at Fig 4.
:0 The oil normally passes from the inlet to the interior of the
cartridge, being deflected at the bottom into the inlet grooves or
channels by a series of radial holes 20 or a plate in spaced
relationship with the:55 bottom of the cartridge, the flow of oil from
the inlet 5 to the outlet 6 being indicated by the arrows in Fig 1 The
stem 16 with the piston valve 18 passes through an inwardly extended
boss 21 in the cover to 17 so as to leave an annular clearance space
22 provided with a port 23 (or ports) so arranged that, when the stem
16 is depressed , the piston valve 18 cuts oft the caritridge 7 from
the outlet 6 and gives the X 5 reverse flow to clear the cartridge, at
the Le same time permitting oil to pass directly i from the inlet 5 to
the outlet 6 via the ce passage 22 without passing through the L_
cartridge as will be readily understood. d A duplex arrangement (Fig
5)' may be 70 g provided by means of a pair of jacketed h casings 2
each containing a cartridge 7. s -Each cartridge is carried from a
stem 24 r extending through the tops of the respee6 -tive casings and
a single two-way oil 75 O supply valve 25 may be provided operated r
by an oscillating handle 26 Each casing s -2 has a pivoted arm 27
provided with a suitable abutment 28 the arrangement being such that
in the operating position 80 (for each casing, the handle 26 moves the
e arm 27 into a position in which it deL presses the stem 24 of the
corresponding cartridge 7 The arrangement otherwise is similar to the
last described construe 85 tion.
The hand operating lever 26 is fixed on the spindle of the two way
valve 25 which 1 is operated by said lever which carries a -stud 26 a
which is adapted to engage one of the levers 28 or 28 a In the
position shown in Fig 5 of the drawings the stud 26 a is engaging the
lever 28 in which position the valve 25 allows the liquid to pass from
the inlet 5 througrh said valve 95 into the right hand cartridge 7
whilst when the hand lever is moved over so that the stud 26 a engages
the lever 28 a, and depressed , the spindle 24 and the left hand
cartridge 7 are depressed whilst the valve 100 is also turned so that
the oil flows through the left hand cartridge the right hand cartridge
being at the same time -raised -and the oil escaping through the
outlet 6 105 I have described the above embodiments of my invention by
way of example, but obviously the constructional arrangements and
details may be varied within the limits of the claims to suit
different re 110 quirements, conditions of working, and the fluids to
be dealt with, and it is to be understood that it is applicable
generally to the heating or cooling and cleansing of liquids 115
