We ALFRED ARNOLD of 76 Verney Road, South Bermondsey, Stationer, and
WILLIAM HOWARD WEBB of 84 Asylum Road Peckham in the County of Surrey
Engineer do hereby declare the nature of this invention to be as follows:-
This Invention relates to open Boilers or Coppers of all kinds whether fixed in
brick setting or portable and has for its object the prevention of the inconvenience
and loss incurred by the boiling over of the liquid or other contents.
Our Invention consists in forming round the outside of the edge or lip of the vessel
or boiler an annular sunk channel which receives any liquid which may boil over the
edge of the lip and allows it to flow back into the body of the vessel or boiler or into
a separate receptacle in lieu of being wasted by flowing over the brick setting or onto
the fire.
According to one mode of carrying out the said invention we make a number of
openings in the side of the boiler just below the lip through which any liquid that
may have boiled over into the annular channel can flow back again into the boiler, or
we connect the said annular channel by a passage, formed either inside or outside the
boiler, with the interior of the boiler itself at or near the bottom thereof, or we attach
one or more flow off pipes to the said annular channel in such a manner as to convey
any liquid that may have boiled over into the said channel to a separate receptacle.
Any ordinary loose lid or cover may be employed fitting inside the outer circum-
ference of the annular channel and resting upon the lip or edge of the boiler which
forms the inner circumference of the said channel.

We ALFRED ARNOLD of 76 Verney Road, South Bermondsey, Stationer and
WILLIAM HOWARD WEBB of 84 Asylum Road, Peckham in the County of Surrey
Engineer do hereby declare the nature of the said invention and in what manner the
sanie is to be performed to be particularly described and ascertained in and by the
following statement :—
"
This invention relates to open Boilers or 'coppers" of all kinds whether stationary
and fixed in brick setting, or portable so as to be placed on an ordinary fire and has
for its object the prevention of the inconvenience and loss incurred by the boiling
over of the contents thereof.
แ
Our invention consists in forming round the outside of the upper edge or lip of an
open boiler,
copper" or other like vessel or utensil usually provided with a loose lid,
an annular trough or channel so constructed as to receive any liquid which may boil
over from the said vessel and enable it to flow back into the body of the said vessel
or in some cases into a separate receptacle or collector in lieu of being wasted by
flowing over the brick setting or onto the floor.
According to one mode of carrying out the said invention we make a number of
apertures in the side of the boiler or vessel just below the upper edge of the lip
thereof through which lateral apertures any liquid that may have boiled over the lip
into the annular trough or channel can flow back again into the boiler or we connect
the said annular trough or channel by one or more descending passages formed either
inside or outside (by preference outside) the boiler such passage or passages opening
into the interior of the boiler itself at or near the bottom thereof, or we attach one or
more flow off pipes to the annular trough or channel in such a manner as to convey
any liquid that may have boiled over into the said channel to a separate receptacle or
collector.
Any ordinary loose lid or cover may be employed fitting loosely inside the outer
rim of the annular trough or channel and resting upon the lip or edge of the boiler
which forms the inner wall of the said channel.
When the improved boilers are to be used as fixed "Coppers" they can be set in
brick work in the ordinary manner hitherto adopted in setting "Coppers" of the
Betal construction

page_text: Similar letters refer to similar parts throughout the several figures.
a is the body of the boiler which when made portable can be provided with any
convenient handle such as 6 for lifting the same. c is the lip or upper edge of the
boiler or vessel. d is the annular trough or channel cast or formed in one with the
boiler or secured round the upper part thereof by rivetting brazing or soldering as
will be readily understood. ee are any convenient number of lateral apertures made
round the upper part of the body of the boiler and opening direct into the surrounding
annular trough or channel d. e' is a passage cast or otherwise formed on the outside
of the boiler for the purpose of connecting the bottom of the annular trough or
channel into which it opens direct, with the interior of the boiler at or near the
bottom thereof through a suitable opening or perforations in the body of the boiler.
9 (figures 1 and 2) is the flow off pipe leading from the annular trough or channel to
any convenient separate receptacle or collector (not shown in our drawings) for
collecting the overflow. h is an ordinary loose "copper" lid or pan lid. i (figures 1
and 2) is the usual projecting flange for supporting the boiler or copper
in its
brick setting which latter being well understood and forming no part of our invention
we have not considered it necessary to illustrate in our drawings. The outer side or
wall of the annular trough or channel d should project a little above the inner wall or
lip c of the boiler say from one to two inches the lid or cover h resting loosely upon
the lip and fitting freely inside the outer rim of the annular trough or channel as
shown in the drawings. Although we have shown in figure 1 the lateral apertures
or perforations e, the descending passage e¹, and the flow off pipe 9, as all applied to
one and the same boiler, it is not necessary to employ the apertures e when the
descending side passage is used nor the side passage when the apertures e are
employed (see fig. 4) and when one or more flow off pipes 9 are fitted to the
annular trough or channel then the lateral apertures and the descending passage may
be dispensed with.
"
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
«
1. An open fixed boiler or copper" provided round the outside of the lip with
an annular trough or channel communicating with the upper part of the interior
of the boiler through lateral apertures or communicating with the bottom of the
same through one or more lateral descending passages as and for the purpose
specified.
2. An open portable boiler or saucepan provided round the outside of the lip with
an annular trough or channel communicating with the upper part of the interior of
the vessel through lateral apertures or communicating with the bottom of the same
through one or more lateral descending passages as and for the purpose specified.
3. Making the outer wall of the aforesaid annular trough or channel to project
above the level of the lip of the boiler or vessel so as to receive the loose lid or cover
thereof as specified.
4. The combination with an open fixed boiler or "copper" provided with the
aforesaid annular trough or channel of one or more flow-off pipes for conducting the
overflow in the channel to a separate receptacle or collector as specified.
