Improved Means and Apparatus for Preventing and Removing
Incrustation Formed in Boilers, Steam Pipes, and other
Vessels.
THOMAS CUDLIPP 8 Church Street London N.W. Laundry and General
Engineer do hereby declare the nature of this invention to be as follows:-
The object of this machine is to prevent and remove the incrustation which now
forms, and is so detrimental to steam, and other boilers, boiling pans, steam pipes.
or anything in which steam or hot water is used, while the said boilers, pans, or
pipes are in use, thus preventing the loss of time caused by stopping the boiler, and
the chipping which takes place, when cleaning boilers under the present system.
The machine consists of a brush or brushes, a scraper or scrapers or any
suitable appliance which I place inside the boiler, tube, pan, or any other article
I wish kept clean I now cause this brush, or scraper, or both, to work in such a
manner that they will rub the different parts of the boiler, where the incrustation
takes place and thus prevent it. In the case of dirty boilers, this will clean them.
This rubbing is obtained by means of suitable gearing fixed either inside the
boiler when space is limited, or fixed outside when most suitable.
These brushes or scrapers may be set to work vertically, horizontally, or in any
suitable manner.
The motion may be continuous, or it may be set to work at intervals. It may
be worked by hand or power.
Improved Means and Apparatus for Preventing and Removing
Incrustation Formed in Bollers, Steam Pipes, and other
Vessels.
I, THOMAS CUDLIPP, 8 Church Street Edgware Road, London N.W. Laundry
and General Engineer 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 this machine is to prevent and remove the incrustation which now
forms, and is so detrimental to steam and other boilers, boiling pans or other
vessels in which steam or hot water is used, thus preventing the loss of time caused
by stopping the boiler, and the chipping which takes place under the present
system.
The machine consists of a brush or brushes, a scraper or scrapers, or any suitable
appliance which I place inside the boiler, pan, or other vessel, I wish to keep
clean; I now cause this brush or scraper or both to work in such a manner that'
they will rub the different parts of the boiler where the incrustation takes place, and
I 'Ning Q, 1

page_text: thus prevent its adherence. This rubbing action is obtained by means of suitable
gearing, for instance, in the case of a vertical boiler of circular shape, 1 employ
one or more circular brushes or scrapers to which a reciprocating motion may be
imparted by means of a crank, eccentric or equivalent device forming part of or
mounted upon a shaft passing through a stuffing box or boxes fixed to the boiler
sides, the said shaft being driven by hand, belt, or any other equivalent and
suitable means. In some cases the shaft may be mounted upon the top of the boiler,
piston rods or plungers passing through glands or stuffing boxes are connected to
the internal brush brushes, or scraper, or both if required, and by means of a
connecting rod or its equivalent to the crank throw, throws, or the like. Again in
some cases the brushes or scrapers, or both may be fitted to horizontal boilers or
like vessels the reciprocating or rubbing motion may then be obtained from a
crank shaft, or eccentric motion mounted upon the end or ends of the vessel, the
piston rods being suitably packed, or the mechanism operating the brushes or
scrapers may be placed within the boiler the driving shaft passing through glands,
either form being driven by belt or other like means. The brushes are preferably
made of iron steel or other metal wire, or of bass, wood, fibre, or the like and the
scrapers of wood or metal either being of square round or other shape so as to
conform to the contour of the vessel to which they are fitted.
To enable my invention to be more readily understood reference is made to the
accompanying drawing in which :-
Fig. 1, shews in part vertical section the application of my improvements to an
ordinary vertical boiler.
Fig. 2, is a plan, the boiler crown being removed.
Fig. 3, is a longitudinal section of a horizontal boiler shewing one method of
applying my invention thereto.
Fig. 4, is an enlarged detail shewing joint and scraper.
In the drawing 1, is the boiler, mounted thereon as shewn is a stuffing box or
gland 2, through which passes a light shaft 3, stepped at its opposite end into a
metallic bearing 4, this shaft is fitted with pulleys 5, which may be replaced by a
winch handle 6, as see dotted lines or by a plain lever for working by hand; keyed
to the shaft are two pinions 7, which engage with the spur wheels 8, running loose
on the studs 9, rivetted or bolted to the boiler sides, each wheel is fitted with a
crank pin 10, which may also in some cases be adjustably mounted, as in a slot so
as to vary the stroke of the brushes. The crank pins pass through the eye 11, of
each connecting rod 12, the other end of each connecting rod being connected by a
bolt or pin 13, as nearly centrally as possible with the frame 14, carrying the
brushes or scrapers 15, see also Fig. 4. These frames which are preferably made
in segments and jointed as at 15, may consist wholly of wood or metal packed with
wood strips 16, in which the wire, fibre, or other material forming the brushes 15,
is mounted, they are so shaped as that the brushes or scrapers may be in close
contact with the boiler shell 1, and fire box 17, or tube replacing it as the case may
be. Each frame 14, is connected to the other preferably by light metal rods 18,
screwed or otherwise fastened to the frame.
The operation of my invention is as follows:
In
Upon turning the shaft 3, by means of a strap engaging with the pulleys or by
hand by means of a winch or lever replacing it, a reciprocating motion is imparted
to the brushes or to the scrapers replacing them by means of the gear wheels 7,
and 8, and the connecting rods coupled thereto. The scale or other sediment
removed thereby falls to the bottom of the boiler or other vessel fitted with my
invention and is cleared out through the mud holes in the ordinary manner.
some cases I find it more convenient to mount the mechanism operating the brushes
or scrapers upon the boiler top or on one end as in Fig. 3. In cases of this kind
I rivét or otherwise fasten a bracket 19, upon the top or end of the boiler, a crank-
shaft 3, is supported in bearings as shewn and the throws 20, connected by rods 12,
to the plungers or pistons 21, passing through stuffing boxes 2, and fastened to the
frames 14, carrying the brushes or scrapers 15, motion being imparted to the crank

page_text: shaft 3, a reciprocating action is conveyed to the brushes which thereby remove
the scale from the sides of the tube or tubes. In Fig. 4, I have shewn an enlarged
view of a scraper, this consists of a thin piece of metal 15" bolted preferably at
right angles to the frame 14.
I do not confine myself to any particular shape or number of brushes or scrapers
as it is obvious that these will vary in a manner depending upon the contour of the
vessel and the requirements of each particular case.
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
claim is :-
1. The improved means and apparatus herein described for preventing and
removing the incrustation formed in boilers and similar vessels.
2. The combination in or with a steam boiler or other similar vessel of a brush,
brushes, or scrapers, or both brushes and scrapers, shaped so as to conform to the
internal contour; to which a reciprocating or scrubbing motion is imparted by the
means and in the way and manner described.
3. The combination in or with a boiler or other vessel of a crank or other shaft
mounted thereon or therein for the purpose of imparting a scrubbing action to an
internal brush, brushes or the like, employed for preventing or removing the
incrustation; substantially as herein described.
