We FRANCIS HABGOOD FREETH and SIDNEY JOB POCOCK trading as Freeth and
Pocock of 8 South Lambeth Road Vauxhall, Surrey, Dairy Implement Manu-
facturers do hereby declare the nature of this invention to be as follows:-
The Milk Can or Beer Can at present in use is constructed of two or more pieces
of metal such as tin which are soldered together to make it watertight.
To dispense with this soldering which is detrimental to the contents and also
to economise the labor and time of the present method of construction we now
construct the milk can or beer can so that the bottom and sides are of one piece of
metal only.

page_text: We FRANCIS HABGOOD FREETH and SIDNEY JOB POCOCK of N° 8 South Lambeth
Road Vauxhall, Surrey, Dairy Utensil Manufacturers do hereby declare the nature
of our invention for IMPROVEMENT IN MILK CANS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
That the body of the Milk Can or Beer Can (hereinafter called the Milk Can) at
present in use is constructed of two or more pieces of metal soldered together to
make it watertight.
Our Invention consists of a vessel, the horizontal section of which is an oval
formed of parallel or slightly tapering sides, the sides and bottom being formed
out of one and the same piece of metal.
The process of manufacture by which our said milk can is made is as follows:-
Having rolled the metal to a thickness suitable for the first operations of our
Patent we take a large sheet of it and we obtain from it by stamping or any other
suitable process, pieces of sheet metal of the proper shape and size.
We make a series of oval dies and receiving beds (see Figs. 1, 2 and 3) and
hereinafter more fully described.
Figure 4 is a plan of the receiving bed shewn in Figure 2.
We then place the shape in the receiving beds in the order in which they are
shewn in the Illustration and upon the upper surface of the receiving beds, guides
(C Fig. 2) are placed to secure the shape being in the right position.
Above the oval recess B of the receiving beds (Fig. 1, 2 and 3) we place a stamp
or die formed in two parts' E and D Fig. 3 which move independently of each
other and are hereafter referred to as the inner and outer die.
By suitable mechanical means such as cranks or cams these dies are brought
down upon the shape of metal in such a way that while the outer die holds
the sheet flat the inner die forces it into the recess of the receiving bed a short
distance. This operation is repeated as often as is found necessary.
For the successive operations after the first the stroke of the inner die E is
lengthened each time till the required depth is obtained.
With some metals it is found necessary to heat the metal shapes between the
processes of stamping.
In Figure 5 (a b and c) we shew the shape of the milk can as made by the
processes herein before described.
We then place the milk can on another machine (Fig. 6) where it is placed in
suitable receiving beds B and C. The stamp D is then brought down by suitable
means, upon the Milk can, and forms the bottom into the desired shape which may
be either flat or slightly concave (Fig. 7 e and f).
By suitable means a wire is put round the outer upper edge, to strengthen it,
and the body of the can is then complete (Fig. 7. d).
It is particularly claimed by us that our Patent is the first successful attempt to
make oval milk cans out of one sheet of metal where the sides of the milk can are
relatively nearly equal to; and in some cases greater than the longest axis of the
bottom of the can.

page_text: Having now particularly ascertained and described the nature of our said
Invention and in what manner the same is to be performed we declare that
what we claim is,
(1). The construction of an oval metal milk cans with parallel or slightly
tapering sides, formed of one piece of metal only.
(2). The shape of the dies and receiving beds for making oval metal milk cans
as herein before described.
(3). The deep stamping process by which oval metal milk cans are stamped out
of one piece of metal the sides being nearly equal and in some cases greater than
the longest axis of the bottom of the can.
