Improvements in the Means of Connection between Mouthpieces,
Tans, and the like, and Enamelled Iron and Steel Utensils, such
as Water Bottles, Urns, and the like.
I, ALFRED ORME, of the firm of Orme, Evans and Company, of Elgin Works,
Wolverhampton in the County of Stafford, Enamellers, 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 :-
According to the mode heretofore practised of connecting mountings, such as
mouthpieces and taps, to enamelled iron and steel utensils, such as water bottles and
urns, by means of a wiped soldered joint, a plain hole is formed through the sheet
metal of the utensil where the mounting is to be fixed, and the enamel is wiped
away, before being fused, from a margin of the outer surface of the metal
immediately around the hole, and after the enamel on the outer and inner surfaces
of the metal is fused the exposed surface around the hole is filed and tinued, and
the mounting is fixed thereto by a wiped soldered joint of which the solder fills in
the exterior angle between the inner end of the mounting and a margin of the tinned
surface of the sheet metal which stands out all round beyond the circumference of
the inner end of the mounting. There are several objections to this method of
fixture, owing to the following causes, namely; difficulty in wiping away the enamel,
before it is fused, to a regular width around the hole; difficulty in filing the surface
from which the enamel has been wiped off, owing to such surface being below the
surface of the surrounding enamel; and the liability of corrosion of the metal,
owing to the edge of the hole being unenamelled and to the liquid for which the
utensil is used coming in contact with such edge and with the unenamelled surface
against which the inner end of the mounting beds.
Now, the object of this invention is to obviate the inconveniences above
enumerated; and this object is effected, according to this invention, by forming the
sheet metal to be enamelled with a part around the hole which is raised in relation
to a part of the metal which is between itself and the hole and to a part of the
metal which surrounds it. The enamel is readily wiped off, before it is fused, from
the top of the raised part, and such part is subsequently readily filed and tinned.
To fix the mouthpiece, tap or other mounting, its inner end is entered within the
space surrounded by the raised portion of the metal, and the filed and tinned surface
of the metal is then entirely around the mounting, instead of passing also under it
as is usual. A wiped soldered joint is then made around the mounting, and some of
the solder fills up the angle between the side of the mounting and the side of the
raised portion of the sheet metal, and thus as the filed and tinned surface is com-
pletely covered by the solder and is still further protected by the solder within the
angle around the mounting, from access of the liquid thereto, all liability of corrosion
through exposure of the surface prepared for the solder is obviated. As the enamel
is not wiped away from the edge of the hole, or from the metal immediately there-
around, the metal is of course not exposed around such edge or otherwise near to
the hole as in the ordinary method of fixing.
That the invention may be clearly understood, I have illustrated the same, by
way of example, according to two modifications thereof, as applied for the purpose
of a screwed-mouthpiece connection with the top of a sheet iron enamelled water
bottle.
Figures 1 and 2 each represent the connection in vertical section.
In Figure 1 the top A of the bottle is shewn to have a raised portion a around
the hole b, and to have the metal at the edge of the hole turned outwards as shewn
The enamel is wiped, before it is fused upon the sheet metal of the utensil,
at c.

page_text: from the top of the raised part a, and such wiped surface is filed and tinned to
receive the solder, after the enamel has been fused. The inner end of the mouth-
piece B is formed with a part d which fits fairly well around the turned up edge c
and enters the annular recess e; and the mouthpiece is fixed by means of a wiped
soldered joint made upon the tinned surface of the raised part a and around the
exterior of the inner end of the mouthpiece, the solder filling the corner, as shewn,
and filling in the angle g between the side of the mouthpiece and the inner side of
the raised part a.
In the modification shewn by Figure 2, the inner end of the mouthpiece Bis
bedded upon a flat portion of the sheet metal which immediately surrounds the
hole, and the edge of which forms the edge of the hole, this modification being
otherwise the same as that shewn by Figure 1.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
1 claim is
1. The method of connecting a mouthpiece, tap or analogous mounting, by a
soldered joint, to an enamelled sheet iron or steel water bottle, urn or like
utensil, by first preparing an unenamelled surface which is spaced from the edge of
the hole by a margin of enamelled surface and which is in position in relation to the
mounting to be entirely protected by the solder from the access thereto of the
liquid in respect of which the utensil is used, substantially as described for
the purpose set forth.
2. An enamelled sheet iron or steel water bottle, urn or like utensil, prepared
with an unenamelled surface surrounding the hole, which is raised in relation to the
metal immediately around and within it, for the purpose of connecting a mouthpiece,
tap or like mounting, to such utensil by a soldered joint, substantially as described
and shewn.
3. The means of connecting a mouthpiece, tap or analogous mounting, by a
soldered joint, to an enamelled sheet iron or steel water bottle, urn or like utensil,
substantially as described and shown.
Dated this 15th day of October 1892.
