Improvements in Machinery for Wiring the Rims of Sheet Metal
Articles or Vessels.
We, ROBERT READ and ALFRED READ, Engineers and FREDERICK JOHN TAYLOR,
Managing Engineer, all of 21 to 27 Bridgewater Street, Liverpool, in the County of
Lancaster, do hereby declare the nature of the said invention to be as follows:-
This Invention relates to wiring the rims of sheet metal articles, or vessels when
such articles, or vessels are of cylindrical, tapered, oval, or like formation.
The object of this Invention is to construct, or provide simple, efficient and cheap
machinery for effecting the wiring of the rims of sheet metal articles, or vessels, when
of cylindrical, tapered, or oval formation, the rim, or rims of such articles or vessels
being previously provided with a groove, or grooves to receive the wire.
A machine according to this Invention consists of a (preferably vertical) revolving
mandril of form to suit the article to be wired. This mandril is mounted and revolves
on a table on which there is provided a sliding roller tool for rounding the metal of
the article over the wire.
In wiring the article, say the upper rim of a bucket, pan, or pail, the article which
is provided with a wiring groove is placed in an inverted position over the mandril, so
that the groove comes between the wiring tool and the mandril. A wire hoop is
placed in the groove and the wiring tool is brought against the groove and turns the
metal thereof round and over the wire.

We, ROBERT READ and ALFRED READ, Engineers, and FREDERICK JOHN TAYLOR,
Managing Engineer all of 21 to 27 Bridgewater Street, Liverpool, in the County of
Lancaster, do hereby declare the nature of the said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention relates to "wiring" the rims of sheet metal articles, or vessels when
such articles, or vessels are of cylindrical, tapered, oval, or like formation.
The object of this Invention is to construct or provide simple, efficient and cheap
machinery for effecting the "wiring" of the rims of sheet metal articles, or vessels,
when of cylindrical, tapered, or oval formation, the rim, or rims of such articles or
vessels being previously provided with groove or grooves.
A machine according to this Invention consists of a vertical revolving mandril of
form to suit the article to be "wired." This mandril is mounted and revolves on a
table on which there is provided a sliding roller tool for rounding the metal of the
article over.
In "wiring" the article, say the upper rim of a bucket, pan or pail, the article
which is provided with a wiring groove is placed in an inverted position over the
mandril so that the groove comes between the wiring tool and the mandril. A wire
hoop may then be placed in the groove and the wiring tool brought against the groove
and turns the metal thereof round and over the wire.
Having thus specified generally the object and nature of our Invention, its
description will be first proceeded with in reference to the Drawings hereto annexed by
way of explaining more fully the construction, operation and effects of apparatus
according to this Invention.
The Drawings and description of them set forth special apparatus designed to apply
the mode or means according to this Invention of "wiring" rims of sheet metal
articles, or vessels which has been above explained.
Figure is a plan of same.
Figure 3 shows the finishing tools of the machine in elevation.
Figure 4 shows the rim of the article provided with the groove prior to being treated
in the machine.
Figure 5 is a detail showing the rim of the article, a wire in such rim and the tool
effecting the "wiring."
Figure 6 shows the rim of the article wired and beaded and the tools used for the
purpose.

With reference to the Drawings a designates the bed and the frame of the machine
b is the mandril placed or working vertically. c the first tool, d a second, or finishing
tool and e a tool to support the rim of the article and take the pressure exerted by the
tool d. * denotes the metal of the article y is the wire and z the lip of the article,
which together with the metal x of the body constitutes or forms the groove which
when a wire ring is employed receives and holds such wire.
We would here state that the example of machine illustrated is provided with a
coned mandril 6, this being the shape to suit and take the article to be operated upon,
namely a common bucket; but we would have it understood that the shape, or con-
figuration of this mandril may be made to suit the form of any article capable of
being operated upon in the machine or in the manner herein described. We would
also state that when it is desired to finish the beading of the metal of the ring (=) as
shown in Figure 6 that is by lapping it completely round the wire the tools d and e
may be dispensed with, or if not dispensed with in the machine, they, of course need
not be used the effect of the tool c alone being sufficient to hold the wire y in its place
(see Figure 5). But at the same time where articles have to be "tinned," or
"galvanized" after "wiring" we prefer to finish the beading, as in Figure 6 as the
space within the rim when "wired" only by the tool c (see Figure 5) would become
filled with the "tinning" or "galvanizing " material and this quantity of the material
would be consequently wasted. On the other hand for ordinary "untinned" or
"ungalvanized "goods, or articles the extent of beading as shown by Figuro 5 is
sufficient.
The tool c is mounted upon a spindle secured to the holder c¹ which slides in and is
held by the guides c³. It is moved up to and away from its work by the lever c² one
end of which passes through the holder c¹ and the other end is connected to a sliding
crosshead by a link f¹. This crosshead works vertically upon the spindle 61 of the
mandril and receives its motion by the foot treadle lever g (which is of the second
order) through the coupling rod 9. At the commencement of the operation the
article is placed upon the mandril with the upper end of its groove uppermost-as will
be understood. The wire y is placed in the groove and the mandril rotated by the
pulleys and bevel wheels. The treadle lever g is then depressed and brings down
the crosshead and thereby forces the long arm of the lever c² away from itself so
causing the holder c¹ and tool c to approch the mandril b. By this action the concave
tool c bends the rim z into the position shown in Figure 5. The return action of the
tool and crosshead is effected by the lever which is of the first order having its
weight at one end and the other end being placed underneath the cross-head as
shown. For goods or articles which are not afterwards "tinned or "galvanized
the above operation might if so desired complete the wiring. But when it is desired
to lap the ring (2) completely round the wire y after the above operation is completed
the tools d and é are brought into action. This is done by raising the end of the
lever having its fulcrum at d-thereby bringing the concave tool d down onto
the metal z and lapping it round the wire y as in Figure 6. The roller tool c is merely
a supporting device.
"
"
When wiring oval shaped articles the mandril b is made oval and the roller tools
would be arranged to move towards and away from the axis of the mandril as it
rotates.
When wiring an article in the above described machine it may be prevented from
rotating with its mandril by placing the operators hand upon the bottom of the article.
The wire can then be easily inserted in its groove and upon raising the hand off, the
article will be rotated and the wire will lie naturally in the bottom of its groove and
in the proper position for wiring. As soon as the tool c is pressed against the metal z
of the rim the article binds on its mandril and is carried round with it. Thus it will
be seen that in wiring the articles it is not necessary to stop the mandril as the article
can be placed on it while rotating, then stopped by the hand (as described) and the
wire inserted, then by removing the hand the article again rotated and the rim is
turned over the wire and the wiring completed, and finally the finished article removed;
all these operations being effected with the mandril rotating. The se operations could

page_text: not be carried out in the manner above described with apparatus in which the mandril
is placed in any other than a vertical or a substantially vertical position. At the same
time no device for holding the article upon its mandril or the wiro in its groove is
required.
We would state in conclusion that the word " wiring" used in this Specification is
a trade term and denotes not only the enclosing of a wire ring in the rim of the article,
but also includes the providing of a turned in edge to the rim of the articles without
such wire ring and consequently the machine herein described as applied to the
"wiring" of articles in which a wire ring is enclosed in a groove is equally applicable
to wiring goods in which no wire ring is inserted, the metal rim being merely turned
round leaving a core, or space which the wire ring would otherwise occupy.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed we declare that what we
claim is :-
