FREDERICK CADBY, of King's Heath, in the County of Worcester, Manager of
Works. "IMPROVEMENTS IN THE MANUFACTURE OF THE METALLIC COVERS AND
RIMS OF MUSTARD POTS, CLARET JUGS, WATER JUGS, AND OTHER LIKE VESSELS
AND ARTICLES."
In making the metallic covers and rims of mustard pots, claret jugs, water jugs,
and other like vessels and articles in the ordinary way the cover is connected to the
rim by a hinge which is soldered to the two parts to be jointed together. The
thumb-bit of the cover is also made separately from the cover and soldered to it.
The rim to which the cover is hinged is made in two pieces, which are soldered
together.
My Invention consists in making the said covers and rims and the parts of the
same from sheet metal in the manner herein-after described, whereby the separate
hinge and thumb-bit and separate parts of the rim and the soldering of the parts
together are dispensed with.
By my Invention simplicity and economy of manufacture are obtained, together
with strength and uniformity in the articles produced.
In making the cover of a mustard pot according to my Invention I cut from
German silver or other sheet metal or alloy a blank having at one side a projecting
piece. This projecting piece is slit or divided into three parts. From the middle
part I make, by the use of press tools worked in a press or stamp, the thumb-bit of
the cover, and from the outer parts of the projecting piece I make the outer
knuckles of the hinge by which the cover is hinged to the rim. At the opposite

page_text: side of the blank to that at which the thumb-bit and outer knuckles are made the
spoon hole in the cover is pierced. The cover of the mustard pot is thus made
with its thumb-bit and knuckle parts of the hinges from one piece of sheet metal.
In making the rim of the mustard pot, to which the cover is to be hinged, I cut
from German silver or other sheet metal or alloy a ring having a width sufficient &
to form the flat part of the rim against which the cover shuts and the collar or
tubular part which is fixed to the mouth of the mustard pot, and at one side of the
said broad ring I form an ear or projecting piece, from which the middle knuckle
of the hinge joint is made.
By means of press tools worked in a press or stamp I bend or shape the ring so 1
as to bring about one-half of it at right angles to the other half, and thereby form
in one piece the flat part of the rim for the cover to shut upon and the tubular or
collar part to be attached to the mustard pot. I also bend the ear or projecting
piece on the ring so as to form the middle knuckle of the hinge joint. By engaging
the middle knuckle on the rim between the outer knuckles on the cover and passing
a joint pin through the engaged knuckles the cover and rim are hinged together.
.
I make the metallic covers and rims of claret jugs, water jugs, and other like
vessels and articles in the manner herein-before described with respect to the cover
and rim of a mustard pot.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by 2
the said Frederick Cadby in the Great Seal Patent Office on the 19th March
1879.
FREDERICK CADBY, of King's Heath, in the County of Worcester, Manager of
Works. "IMPROVEMENTS IN THE MANUFACTURE OF THE METALLIC COVERS AND
RIMS OF MUSTARD POTS, CLARET JUGS, WATER JUGS, AND OTHER LIKE VESSELS 2
AND ARTICLES."
In making the metallic covers and rims of mustard pots, claret jugs, water jugs,
and other like vessels and articles in the ordinary way the cover is connected to the
rim by a hinge which is soldered to the two parts to be jointed together. The
thumb-bit of the cover is also made separately from the cover and soldered to it.
The rim to which the cover is hinged is made in two pieces, which are soldered
together.
My Invention consists in making the said covers and rims and the parts of the
same from sheet metal in the manner herein-after described, whereby the separate
hinge and thumb-bit and separate parts of the rim and the soldering of the parts
together are dispensed with. By my Invention simplicity and economy of
manufacture are obtained, together with strength and uniformity in the articles
produced.
In making the cover of a mustard pot according to my Invention I cut from
-German silver or other sheet metal or alloy a blank having at one side a projecting

page_text: {
piece. This projecting piece is slit or divided into three parts. From the middle
part I make, by the use of press tool worked in a press or stamp, the thumb-bit of
the cover, and from the outer parts of the projecting piece I make the outer
knuckles of the hinge by which the cover is hinged to the rim. At the opposite
side of the blank to that at which the thumb-bit and outer knuckles are made the
spoon hole in the cover is pierced..
The cover of the mustard pot is thus made, with its thumb-bit and knuckle parts
of the hinge, from one piece of sheet metal.
In making the rim of the mustard pot to which the cover is to be hinged, I cut
from German, silver or other sheet metal or alloy a ring having a width sufficient
to form the flat part of the rim against which the cover shuts and the collar or
tubular part which is fixed to the mouth of the mustard pot, and at one side of the
said broad ring I form an ear or projecting piece from which the middle knuckle
of the hinge joint is made. By means of press tools worked 'in a press or stamp I
bend or shape the ring so as to bring about one-half of it at right angles to the
other half, and thereby form in one piece the flat part of the rim for the cover to
shut upon and the tubular or collar part to be attached to the mustard pot. I also
bend the ear or projecting piece on the ring so as to form the middle knuckle of
the hinge joint. By engaging the middle knuckle on the rim between the outer
knuckles on the cover and passing a joint pin through the engaged knuckles the
cover and rim are hinged together.
Instead of making the rim from a broad ring a circular disc may be used.
I will now proceed to describe, with reference to the accompanying Drawing, the
manner in which my Invention may be performed.
Figure 1 represents in plan and section the blank from which I make the cover
of a mustard pot, the said blank being cut from sheet German silver or other sheet
metal or alloy. At one side of the blank, Figure 1, is a projecting part marked a,
from which the thumb-bit and outer knuckles of the joint of the cover are made,
and at the opposite side of the blank, Figure 1, is a hole or opening 6 which forms
the spoon hole in the finished cover. I take the blank, Figure 1, and divide or
slit the projecting piece a into three parts, as represented in Figure 2, the said parts
being marked respectively c, d, c. From the middle part d the thumb-bit of the
cover is made, and from the outer parts c, c, the outer knuckles of the joint are
made. The middle part d of the projecting piece on the cover is next raised out of
the plane of the cover part e and an ornamental figure given to it. The thumb-bit
is thereby completed, as represented in plan in Figure 3 and section in Figure 4,
where the finished thumb-bit is marked d.
The knuckle parts c, c, are at the same time or by a subsequent process bent
into the form best seen in the section, Figure 4. By the operation of the same pair
of dies by which the bending of the thumb-bit is effected the greater part of the
cover c is raised out of the plane of the marginal part, so as to leave a flange around
the circumference of the cover, as represented in Figures 3 and 4. The cover is
completed by bending the knuckle parts c, c, into a tubular figure, as represented in
plan in Figure 5 and elevation in Figure 6. The cover of the mustard pot, its
thumb-bit d, and knuckles c, c, are thus made from one piece of sheet metal.
In making the metallic rim of the mustard pot I cut out at a press the circular
blank represented in Figure 7, and by means of raising tools worked in a press I
raise the said blank into the cup form represented in plan in Figure 8 and section
in Figure 9. From the top or flat part of the partly-made rim I pierce and raise
the projecting piece from which the middle knuckle of the hinge or joint is to be
made. I take the partly-made rim, Figures 8 and 9, and cut out by the operation
of a pair of cutting tools worked in a press the greater part of the flat top of the
rim, as represented in plan and elevation in Figures 10 and 11, leaving only the
flat part or flange g upon which the cover shuts. The rim is finished by bending
or shaping the projection f into a tubular form, thereby forming the middle knuckle
of the joint or hinge, as represented in plan in Figure 12 and section in Figure 13,
where the said middle knuckle is marked i. There is thus formed from one piece

page_text: of metal the flat flange or part g of the rim against which the cover shuts and the
collar or tubular part h which is fixed to the mouth of the mustard pot together
with the middle knuckle i of the joint or hinge.
Instead of making the rim from a disc of sheet metal, as described and repre-
sented, a broad ring may be first taken and by subsequent operations brought into
the form represented in Figures 12 and 13.
Figure 14 represents in plan, Figure 15 in elevation, and Figure 16 in section, a
metallic cover and its rim made according to my Invention, the cover being hinged
or jointed to the rim by engaging the knuckle parts c, i, c, together and passing a
joint pink through them and rivetting the said pin in the usual way.
I make the metallic covers and rims of claret jugs, water jugs, and other like
vessels and articles essentially in the manner herein-before described and illustrated
in the accompanying Drawing with respect to the cover and rim of a mustard pot.
The cutting-out, piercing, and shaping, or raising tools which I use in carrying
my Invention into effect are of the kind commonly used in cutting out, piercing,
and shaping metals: for other purposes, and constitute no part of my Invention, I
therefore do not think it necessary to describe and represent the said tools.
Having now described the nature of my Invention and the manner in which the
same is to be performed, I wish it to be understood that I do not limit myself to
the precise details herein described and illustrated, as the same may be varied
without departing from the nature of my Invention,―
But I claim as my Invention of improvements in the manufacture of the metallic
covers and rims of mustard pots, claret jugs, water jugs, and other like vessels
and articles,
First. Making the said covers and their thumb-bits and the knuckle parts of the
hinge or joint from one piece of sheet metal, substantially as herein-before described
and illustrated in the accompanying Drawing.
Secondly. Making the said rims and the knuckle parts of the hinge or joint
from one piece of sheet metal, substantially as herein-before described and illustrated
in the accompanying Drawing.
In witness whereof, I, the said Frederick Cadby, have hereunto set my hand
and seal, this Seventeenth day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
Witness,

Clerk to George Shaw,
