Improved Method of Fixing and Mounting Metal Rims or Hinged
Covers upon Enamelled Tea-pots, Coffee-pots, or other Enamelled
Articles.
WILLIAM ROBINSON Lower Stafford Street Wolverhampton Hardware Merchant
I do hereby declare the nature of this invention to be as follows:-
Enamelled ten pots, coffeepots, hot water jugs with hinged covers have hitherto
been supplied completely enamelled after made. The hinged cover so produced
has been not only clumsy in appearance-but has proved in use to be unpractical
and unsatisfactory and in addition has a tendency to chip the enamel. The hinge
is also liable to break off owing to the fact that the process of enamelling has the
tendency to give the hinge a brittle character.
Now this invention has for its object a method of fixing or mounting tin, brass,
copper or other metal rims, hinges and covers upon enamelled teapots, coffee pots,
hot water jugs and similiar articles in such a manner as secures all the great
savitary advantages of an enamelled pot and at the same time provide a metal rim,
hinge and cover which are strong, durable and practical, and which does not injure
the enamel.
The above object is effected, according to this invention, by fixing one or more
rivets close to the top of the rim of pot and slightly projecting on the outside of
the pot. This is done before the articles are enamelled in order to ensure a smooth
and perfect surface of enamel, free from all defects. The parts where the rivet or
rivets are placed may be countersunk if required to enable the rim or hinge to be
fixed and mounted, if necessary, flush with the pot. A small piece of tin or other
metal pressed or cut to the required shape, with holes made to receive the rivet or
rivets, is then fitted on, and securely fixed and soldered or braized on to the rivets.
A specially designed metal rim falls inside the pot in such a manner as to form a
ledge the edge of which is so constructed as to prevent any injury to the hand
when the pot is being cleaned. The ledge so formed permits the sieve made of
linen, or zinc or other metal to rest in a convenient manner. The top of the rim is
then rolled or spun over the top edge of the enamelled pot-the part which has
been affixed and secured to the rivets as already described being rolled under this
rim and so making the attachments firm and secure, and forming a groundwork for
mounting the hinge or hinged cover securely to the pot by means of soldering or
braizing.

Covers upon Enamelled Tea-pots, Coffee-pots, or other Enamelled
Articles.
1, WILLIAM Ronissos, of Lower Stafford Street, Wolverhampton in the
County of Stafford, Hardware Merchant, 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 :-
Enamelled ten-pots, coffee-pots, hot water jugs and the like, fitted with hinged 5
cosers, have hitherto or usually been completely enamelled, incluling the covers,
after the covers have been attached. The hinged enamelled covers are clumsy in
appearance and are found in use to be umpractical and generally unsatisfactory, and
the enamel has a tendency to chip off. Moreover, the process of enamelling has a
tendency to give the hinge a brittle character, and thus render it liable to break.
Now, this invention has for it- object means of fixing to coffee-pots hot water
jugs and the like alter they have been enamelled, when such is required, metal rims,
and of mounting upon ten-pots, coffee pots, hot water jugs and the like, after they
have been enam Hed, hingel metallic covers, in such mainer that no part of the
rim in the one case, and no part of the hinge in either case, is enamelled and that
no injury is done to the enainel of the utensil, and that all the sanitary advantages
of an enamelled utensil are nevertheless secured.
The main feature and basis of the invention consists in the means adopted for
forming a metallic groundwork surface, without exposing a metallic surface at the
interior of the utensil, to which the hinge or rim or both may be soldered or
brazed. These means consist in passing a metallic peg or pegs through a hole or
holes formed in suitable position through the metal of the utensil, before the utensil
is enamelled, until the head or heads come against the inner face thereof, then
enamelling the whole surfare of the utensil except for the outer end or ends of the
peg or pegs whereby the head or heads of the peg or pegs are coated with enamel
and the peg or pegs held in place, and finally passing a metal plate over the outer
or exposed end or ends of the peg or pegs and soldering or brazing it thereto. This
plate forms a groundwork to which the hinge or rim or both may be soldered or
brazed. If during the process of enamelling, any enamel should adhere to the end
or ends of the peg or pegs, such is removed previously to fixing the plate thereto.
Figures 1, 2 and 3 of the drawings herewith illustrate a convenient means,
according to this invention, of forming the metallic groundwork to which to solder
or braze the hinge of a cover of an enamelled tea-pot or other enamelled utensil of
the same kind. Of these views, Figure 1 is a plan of a portion of the hinder part
of an enamelled ten-pot previously to the hinge of the cover being fixed thereto
Figure 2 is a detached cige view and plan of the metal plate to which the hinge is
fixed; and Figure 3 is an enlarged vertical sectional view of the hinder portion of
the upper part of the pot, a portion of the handle being shewn by broken lines
a shews the thickness of the sheet metal of which the pot is made, and b show
respectively, the inside and outside coatings of enamel. Two pegs are pushed
prior to the pot being enamelled, through openings formed through the bottom of
sunk portion d formed in the top thereof. The heads of these pegs come agains
the inside of the sheet metal a, as shewn. The pot is then enamelled inside an
outside, the inside layer of enamel covering the heads of the pegs, as shewn; bu
the outwardly projecting portions of the pegs are left exposed. A plate f, havin
holes g therethrough for the pegs, is then passed down into the recess d and ove
the pegs, and is soldered or brazed to the pegs. This plate is omitted in Figure
but is shewn in place in Figure 3. The hinge of the cover is then soldered o

page_text: Led to the plate f. The purpose of forming the recess d is to ensure the outer
face of the plate being flush, or approximately so, with the surrounding surface of
the pot; but such recess is not of course essential, as the plate may stand above
the surrounding surface of the pot, if desired. The flap of the hinge which is to
be fixed to the body of the pot may, if preferred, be formed with holes such as g
and be passed down over the ends of the pegs e and be soldered or brazed thereto,
instead of using a plate as the foundation to which to solder or braze the hinge;
but it is much preferred to use the foundation plate and to solder or braze the
hinge thereto.
Figures 4, 5 and 6 of the drawings illustrate a convenient means, according to
this invention, of fixing to an enamelled coffee pot, or other enamelled utensil of
the same kind such as a hot water jug, a metallic rim and of mounting a hinged
cover to such pot or utensil. Of these views, Figure 4 is an enlarged sectional
elevation through the side of the upper portion of the utensil to which the hinge is
to be fixed, shewing the metallic rim placed thereupon, but not secured in place.
Figure 5 is a corresponding view to Figure 4, and is drawn to the same scale, but
shews the metallic rim and hinge to be securely fixed in place, and shews also a
portion of the cover. Figure 6 is a back elevation of the upper portion of the
utensil to half the scale of that to which Figures 4 and 5 are drawn, and shews
the base plate for the hinge, but the hinge itself is omitted, and the middle portion
of the rim is shewn as broken away so as to leave the entire plate exposed to view.
In this particular instance, a single peg c¹ is shewn as passed through the wall of
the utensil, and is held in place by the enamel as in the case of the pegs c before
described. A base plate, corresponding to the plate before described, but
having a single hole formed therethrough, is passed over the peg c', and soldered or
brazed thereto. The upper portion of this plate follows the curve of the exterior of
the beaded or wired edge of the utensil, up to about the middle thereof. The rim j
is first formed of a trough or channel shape to pass down over the edge of the
utensil, and subsequently the portion thereof is spun in from its position shewn
by Figure 4 under the beaded or wired edge of the utensil, and for the distance
thereof which extends along the plate f¹ such portion is turned in against the
upper portion of the plate so that such portion of the plate is between the beaded
or wired edge of the utensil and the portion of the rim, as shewn by Figure 5.
The rim is soldered or brazed to the plate and thus prevented from being turned
upon the utensil. The flap of the binge which is to be fixed to the utensil is
soldered or brazed both to the plate and to the rim j. The plate, thus forms
the base to which both the rim and flap of the hinge are securely fixed. As the
upper portion of the plate f' fits under the beaded or wired edge of the utensil,
and is itself secured to some extent by the rim, a single peg is sufficient, but of
course more than one such peg may be used if preferred.
The
The rim as shewn in section by Figures 4 and 5 is specially shaped to adapt it
for a coffee pot, having a portion m which extends a short distance down into the
pot and is formed with an inward flange n upon which the strainer may rest.
edge of the flange is folded back underneath as shewn, so ng to prevent
the exposure of a sharp edge which would be likely to injure the hand in cleaning
the pot. If the rim is for a hot water jug only, the portion inside the utensil woula
be close thereagainst all round and extend a less distance down than in the case of
a coffee pot.
The flap of the hinge may be shaped, as will be obvious, for being passed over
the ends of two pegs, each like the peg c, and soldered or brazed thereto, instead
of using a foundation plate f¹, the rim being held from turning by soldering or
brazing it to the flap /; but it is much preferred to use the flap as described.
It will usually be preferred, in adopting this invention, to fix and mount upon the
enamelled utensils unenamelled metallic covers, but enamelled covers may be used,
if desired, in which case the enamelled cover is surrounded with a metal rim to
which one flap of the hinge is soldered or brazed, the other flap of the hinge being
fixed to the utensil in the improved manner above described.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The improved method of fixing and mounting a hinged cover to an enamelled
tea pot, coffee pot, or other enamelled article, according to which a peg or pegs are
passed through the metal of the utensil prior to the same being enamelled, and the
head or heads thereof are coated with enamel to prevent a metallic surface being
exposed at the interior of the utensil, and after the utensil has been enamelled a
foundation plate is soldered or brazed to the outer end or ends of such peg or pegs,
which are left unenamelled for such purpose, and the hinge is soldered or brazed to
such foundation plate, or in lien of such foundation plate the hinge is soldered or
brazed direct to the exposed outer end or ends of the peg or pegs, substantially as
described.
2. The improved method of fixing and mounting a metallic rim to an enamelled
coffee pot, hot water jug or other enamelled article, which consists in the use of 8
peg or pegs passed through the metal of the utensil prior to the same bring
enamelled and covering the head or heads of such peg or pegs with enamel to
prevent a metallic surface being exposed at the interior of the utensil and after
the utensil has been enamelled soldering or brazing a foundation plate to the outer
end or ends of such peg or peg-, which are left unenamelled for such purpose, and
finally soldering or brazing the inetallic rim to such foundation plate, substantially
as described.
3. The improved method of fixing and mounting a metallic rim to an emmeiled
collee pot, hot water jug, or other enamelled article, which consists in the use of a
peg or pegs passed through the metal of the utensil prior to the same being
enamelled, and covering the head or heads of such peg or pegs with enamel to
prevent a metallic surface being exposed at the interior of the utensil, and after the
utensil has been enamelled soldering or brazing a foundation plate to the outer end
or ends of such peg or pegs and then turning in the outer edge of the rim under
the beaded or wired edge of the utensil and enclosing the upper portion of the
plate aforesaid between the turned-in portion of the rim and the underside of the
beaded or wired edge of the utensil, and finally Boldering or brazing such edge of
the rim to the plate, substantially as described.
