page_text: LETTERS PATENT to Robert Stroud, of the firm of R. Stroud and Company
of the Niphon Works Wolverhampton in the county of Stafford for an
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF "NECKS" FOR CANS
OR CHURNS FOR THE TRANSPORT OF MILK AND THE LIKE
"
PROVISIONAL SPECIFICATION left by the said Robert Stroud at the Office
of the Commissioners of Patents on the 3rd September 1883.
ROBERT STROUD of the firm of R. Stroud and Company of The Niphon Works,
Wolverhampton in the county of Stafford, "IMPROVEMENTS IN THE MANUFACTURE
OF NECKS FOR CANS OR CHURNS FOR THE TRANSPORT OF MILK AND THE
LIKE
"
"
"
This invention has for its objects improvements in the manufacture of necks for
cans or churns for the transport of milk and the like.
Hitherto such necks have been made of malleable cast iron in a circular shape
but it is found that in the cooling or by some other influence the finished castings
are rarely regular in shape.
The necks have also been produced from sheet steel or iron in two or more pieces
grooved or seamed together such process of grooving or seaming together necessarily
resulting in an uneven surface and irregularity in shape.
The result of the irregularities in the shape of either the malleable cast or hand
made necks so grooved or seamed is that each lid is necessarily required to be
made and fitted to a particular can or churn. Now my invention consists in the
adaptation of the process of stamping to the manufacture of the said necks whereby
I am enabled to produce necks that are perfectly regular in their shape and thus
enabling lids to be used which are interchangeable and uniform in their fitting
diameter and as a result the possibility of the milk or other fluid splashing out
between the lid and the neck when in motion is reduced to a minimum.

page_text: By my process of manufacturing necks the cost is considerably reduced and
equal strength is also secured with much less weight and they are much more
easily cleaned from the fact that sheet steel or iron presents a greatly improved
surface when tinned than malleable cast iron.
The necks when stamped out have their upper rims preferably turned in on a
lathe over a stout wire inserted so as to form a continuous annular head or ring on
their peripheries. The seal for the lid (which is formed to correspond) is made on
the neck by a suitable portion of the die.
The necks may be attached to the can body by any suitable means and the lid
likewise secured or locked.

ROBERT STROUD, of the firm of R. Stroud and Company of the Niphon Works,
Wolverhampton in the county of Stafford "IMPROVEMENTS IN THE MANUFACTURE
OF " NECKS FOR CANS OR CHURNS FOR THE TRANSPORT OF MILK AND THE

""

This invention has for its object improvements in the manufacture of necks for
cans or churns for the transport of milk and the like.
Hitherto such necks have been made of malleable cast iron in a circular shape
but it is found that in the cooling or by some other influence the finished castings
are rarely regular in shape.
The Decks have also been produced from sheet steel or iron in two or more pieces
grooved and seamed together such process of grooving or seaming together
necessarily resulting in an uneven surface and irregularity in shape.
The result of the irregularities in the shape of either the malleable cast or hand
made necks so grooved or seamed is that each lid is necessarily required to be
made and fitted to a particular can or churn.
Now my invention consists in the adaptation of the process of stamping to the
manufacture of the said necks whereby I am enabled to produce necks that are
perfectly regular in their shape and thus enabling lids to be used which are inter-
changeable and uniform in their fitting diameter and as a result the possibility of
the milk or other fluid splashing out between the lid and the neck when in motion
is reduced to a minimum.
By my process of manufacturing necks the cost is considerably reduced and
equal strength is also secured with much less weight and they are much more
easily cleaned from the fact that sheet iron or steel presents a greatly improved
surface when tinned to that of malleable cast iron.
The necks when stamped out have their upper rims preferably turned in on a
lathe over a stout wire inserted so as to form a continuous annular head or ring on
their peripheries. The seat or bearing for the lid (which lid is formed to correspond
therewith) is stamped on the neck by a suitable portion of the die.
The necks may be attached to the can body by any suitable means and the lid
likewise secured or locked.
Referring to the accompanying drawings and to the figures and letters of
reference marked thereon
Figure 1 shows a plan view of a neck.
Figure 2 an elevation of same.
Figure 3 a section through neck.
Figure 4 a sectional elevation view of the die
In carrying my invention into practice I find it most advantageous to use sheet
steel as the material for forming my necks and after cutting or stamping out a
sheet to the required size I place the same on a suitably formed die and fitted with
a corresponding matrix or swage which being worked by suitable means as is well
understood descends and forces the sheet steel into the die or the die and sheet may
be pressed against a fixed matrix or swage block. The lip or flange of the neck is
then turned in on the lathe against a fixed tool the stout wire being inserted as
shewn in Figure 2.
In these figures A is the neck complete B the lid as shown in Figure 2 stamped
out of sheet steel or iron and with a ventilating cone The lid may be secured by
hasp or otherwise and I do not claim the lid or method of securing the same.

page_text: It will be seen my invention enables me to produce necks at a much cheaper
rate than usual and which is especially of value the lids if damaged are easily
replaced owing to the various sizes manufactured being uniform.
The form of neck and die for making the same can be of course varied without
departing from the principle of my invention.
Having now described the nature of my said invention and particularized the
manner of performing the same I would have it understood that what I claim as
novel and original and desire to secure under the before in part recited Letters
Patent is :-
The manufacture of necks for cans or churns for the transport of milk and the
like by stamping the same from sheet iron, steel or like metal in a suitable die or,
mould substantially as described.
In witness whereof I the said Robert Stroud have hereunto set my hand and
seal this twenty ninth day of February in the year of our Lord 1884.
