Improved Apparatus for Cleansing Pipes and Tubes, especially such
for Drawing or
and other
Conducting Beer
as
used
are
Beverages from Casks or Barrels.
I, SAMUEL GEORGE BAKER COOK, of 96, Queen Street, Cheapside, in the
County of London, Manufacturer, do hereby declare the nature of this invention
to be as follows;-
It is a well known fact that in the pipes, tubes or "coils" used in drawing beer
and other fluids from the cask there is a sedimentary deposit of dregs and other
filthy and injurious elements which finally obstruct the flow of the liquids; and
various chemical substances have been resorted to, to clean the pipes or tubes by
reducing this sediment to solution and passing it off with a flow of water. It is also
well known that in many cities of Europe travelling boilers upon the streets furnish
steam through hose or other elastic connection with the liquor pipes or tubes which
disengages the sedimentary deposits from the inner walls of the same and that after
being thus disengaged it is passed out by a flow of hot water from the boiler
effectually cleansing the pipes which are then cooled by passing a flow of cold
water through them placing them again in condition for service; this street system
while efficient is expensive, cumbersome and begets a feeling of dependence on the
part of the owners of the pipes towards the owner of the steam cleansing and
washing boiler.
The purpose and object of my invention therefore is to furnish a small compact,
cheap, and at the same time an efficient water heating and steam generating
apparatus which in connection with the ordinary flow of water in city pipes shall
furnish at great convenience and small cost all the requisites of this well known
and most efficient system of pipe and tube cleaning viz. steam and hot and cold
water.
The particular features of my machine or device are such that no skill is required
to operate it and that it is adaptable to any size or length of "coil" pipe or tube
ordinarily used in saloons without increasing its size and is easily attached to the
water and gas pipes-gas being used as fuel-and is then ready to connect with
such pipes as may need cleaning.
My machine or device therefore enables each owner to clean his own pipes
thoroughly and economically the apparatus being constructed as follows.
I provide an annular conical formed base centrally provided with a basin shaped
burner base forming part of a Bunsen burner of special construction hereinafter
described.
Upon the conical base I mount a cylindrical case or body provided near its base
with an in-going draught regulator so that by bringing vent holes in an enclosed
circular band or ring, into position with corresponding holes formed in the cylindrical
case, the in-going draught can be increased or diminished at will.
Within the cylindrical case or body and in close proximity to its inner walls I
place a water heating coil and within the water heating coil I provide another coil
in which steam is to be generated. The steam coil is arranged conically to surround
the conical Bunsen burner herein before referred to and both the water heating coil
and the steam coil are connected at their lower ends by a combination stop flow,
jet and drain valve hereinafter described.
The upper extremity of the cylindrical case or body is provided with a cover
through which a regulating valve connects a water supply pipe with the water

page_text: "
heating coil and a similar regulating valve connects the steam coil with suitable
piping leading to the pipes tubes or
"coils
to be cleansed. The said cover is
provided with a movable register to regulate the out-going draught in accordance
with the regulated in-going draught hereinbefore referred to and is secured upon
the cylindrical case or body by means of a central binding bolt which serves
unite the cover with the base and at the same time to bind together the several
parts of which the Bunsen burner is formed.
to
The Bunsen burner consists of a basin shaped base, centrally formed in the base
of the apparatus. Upon this basin shaped base several annular conical section
pieces are built up within the steam coil, the number of these sectional parts
depending upon the amount of heat required to be produced. The upper one of
these sectional parts is provided with a cover through which the binding bolt
passes and so secures the parts of the Bunsen burner in position as well as binding
the base and cover of the apparatus in position upon the cylindrical case or body.
The basin shaped base of the Bunsen burner is provided with a gas inlet con-
trolled by a stop-cock and air inlets governed by a rotatable register plate and the
sectional parts of the burner are each provided with escape holes at their bases and
flame deflectors immediately above the same.
The combination stop flow, jet and drain valve employed to connect the water
heating coil and the steam coil at their lower ends, is a plug cock with ports so
arranged in the plug that by turning it into various positions it may in combination
with a pet cock communicating therewith either be employed to drain the steam
coil or to supply from the water heating coil a jet of water to be transformed into
steam in the steam coil, or a copious flow of hot water passing through both the
coils which after extinction of the burner, becomes a flow of cold water as required.
The operation of my device is as follows:
The connections are made with the supply of water and gas and also with the
tubes to be cleaned; the combination stop flow, jet and drain valve is closed, the
gas then turned on and lighted; water is then passed into the water heating coil
through the water regulating valve and allowed to heat until the steam coil is hot
enough to generate steam, the combination stop flow, jet and drain valve is then
turned into position a small jet of hot water is thrown from the water heating coil
to the steam coil and instantly converted into steam which passes through the
steam regulating valve and the connecting pipes through the pipes, tubes or
"coils" to be cleaned (should however these pipes tubes or coils be of extra-
ordinary length or very much obstructed, a momentary closing of the steam
regulating valve will accumulate steam and force enough to accomplish the
cleaning) then by again turning the combination stop flow, jet and drain valvo
a flow of hot water is passed through thoroughly washing out the impurities
liberated by the steam and then by turning off the gas, the flow of water gradually
becomes cold and thus places the pipes in a condition for immediate use.

COMPLETE SPECIFICATION.
Improved Apparatus for Cleansing Pipes and Tubes, especially such
as are used for Drawing or Conducting Beer and other
Beverages from Casks or Barrels.
I, SAMUEL GEORGE BAKER COOK, late of No. 96, Queen Street, Cheapside,
London, now of No. 27, Eagle Wharf Road, Hoxton, in the County of Middlesex,
Manufacturer, 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:-
It is a well known fact that in the pipes, tubes or
"coils
39
used in drawing beer

page_text: and other fluids from the cask there is a sedimentary deposit of dregs and other
filthy and injurious elements which finally obstruct the flow of the liquids; and
various chemical substances have been resorted to, to clean the pipes or tubes by
reducing this sediment to solution and passing it off with a flow of water. It is
also well known that in many cities of Europe travelling boilers upon the streets
furnish steam through hose or other elastic connection with the liquor pipes or
tubes, which disengages the sedimentary deposits from the inner walls of the same
and that after being thus disengaged it is passed out by a flow of hot water from
the boiler effectually cleansing the pipes which are then cooled by passing a flow
of cold water through them, placing them again in condition for service; this
street system while efficient is expensive, cumbersome, and begets a feeling of
dependence on the part of the owners of the pipes towards the owner of the steam
cleansing and washing boiler.
The purpose and object of my invention therefore is to furnish a small, compact,
cheap and at the same time an efficient water heating and steam generating
apparatus which in connection with the ordinary flow of water in city pipes shall
furnish at great convenience and small cost all the requisites of this wellknown
and most efficient system of pipe and tube cleaning viz. :-steam, hot and cold
water and the particular features in my machine or device are such that no skill
is required to operate it and that it is adaptable to any size or length of coil, pipe
or tube ordinarily used in saloons without increasing its size and is easily attached
to the water and gas pipes, gas being used as fuel, and is then ready to connect with
such pipes as may need cleaning.
The purpose and object of my invention therefore is to enable each owner to
clean his own pipes thoroughly and economically and I accomplish this with the
following illustrated apparatus in all the figures of which like letters and numerals
refer to like parts.
Figure 1 is a vertical section of the device.
Figure 2 is a section taken upon lines at right angles to Fig. 1.
Figure 3 is a plan of the combination spray cock showing its connection with the
lower ends of the water and steam coils (enlarged).
Figure is a section through the same taken in the line of the pipes and the
vertical plane (enlarged).
Figure 5 is a section through the same taken upon the lines of Figure 2
(enlarged).
Figure 6 is a section of burner such as is intended for gas (enlarged).
Figure 7 is also a section of burner and shows the form of top (enlarged).
Figure 8 is a plan and section of the burner air regulator (enlarged).
In describing my invention A is an annular conical formed base centrally pro-
vided with the basin shaped burner base a, core a¹, gas inlets a² and air inlets a³
also section-built-up burner as a³, a³ aª and cap a (any of the sections may be a
cap if the heat produced is sufficient) and all are provided with the escape holes (2ª
and the flame deflectors a². a is a boss centrally located to accommodate the
binding bolt.
B is a barrel shaped case or body resting upon the base A and
provided with an ingoing draught regulator b which by bringing the vent holes 63
into position with those b¹ of B can increase or diminish it at will.
C is a cap plate resting upon B and is provided with escape or ventilating
draughts bosses c¹, c², and c for the water pipe, binding rod and steam pipe and a
regulating plate & which can be made to slide over the draught holes c.
D is the water inlet pipe connected with the supply, d the regulating valve, d' the
water heating coils situated within and near the inner walls of the case B.
E is a combination stop flow jet and drain valve connecting the lower end of the
downwardly coiled water heating pipe with the lower end of the upwardly coiled
steam generating pipe f¹ in which is the supply or water port and e¹ the exhaust
or steam port the auxiliary flow core the drain core and et the pet cock c³ the
plug provided with an angle core 6 (the position shown is the position for draining
the water pipe if the pet cock is open and if closed, of jetting a small stream of

page_text: water into the pipe f¹) through the jet core e and it is evident that by turning this
angle core the pipe f may be drained into the core 3 or supplied with a flow
from the core ; e is a binding plug e the operating lever and wheel e the pet
or drip cock; Fis the exhaust or steam pipe connected with the pipes or tubes to
be cleaned; is a valve; f¹ the steam generating coil connected at the lower end
with the valve or cock E and the water heating coil d¹. G is the air regulator
having the core g and the air ports y corresponding to the gas supply pipe H at h
and the air ports a³ of the core a¹.
On account of the intense heat to which the combination stop flow jet and drain
valve E may be subjected when fixed as shown within the outer casing of the
apparatus it may be desirable to alter the form of the cock so that the body
thereof fitted with the plug e may be brought to the outside of the apparatus and
there may also be provided an index on the body of the cock and a pointer upon
the plug to point upon the index to the exact positions into which the plug is to be
set to open communication for steam, hot water and cold water as required.
The operation of the apparatus is as follows
The connections are made with the supply of water and gas and also with the
tubes to be cleaned; the valve E is closed the gas then turned on and lighted;
water is then passed into the coil d' through the valve d and allowed to heat until
the coil is hot enough to generate steam, the valve E is then turned into the
position shown in Figure 4 and a small jet of hot water is thrown from the coil d¹ to
the coil f and instantly converted into steam which passes through the valve and
the pipe F through the pipes or tubes to be cleaned (should however these pipes
or tubes be of extraordinary length or very much obstructed a momentary
closing of the valve f will accumulate steam and force enough to accomplish the
cleaning) then by again turning the valve E a flow of hot water is passed through
thoroughly washing out the impurities liberated by the steam and then by turning
off the gas the flow of water gradually becomes cold and thus places the pipes in
a condition for immediate use.
It will be observed that the body of the valve E (or when the valve E is fitted
outside the apparatus, then that part to which the valve E is connected and which
serves as a union for the water heating coil and the steam generating coil f¹) is
merely passed through an opening in the shell B without any water, air or steam
tight fit, these being unnecessary and that by simply removing the plug of the
valve E and the pet-cock (or the complete valve E when fitted outside) the
remaining part can be moved inwardly so as to be entirely inside of the shell.
Now by simply removing the nut at the upper end of the binding rod, the cap and
coils may be lifted bodily away from and out of the shell for the purpose of
cleaning or repair.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
