I SAMURL BRASSINGTON BAMFORD of the Firm of H. Bamford & Sons
Agricultural Engineers Uttoxeter in the County of Stafford do hereby declare the
nature of this invention to be as follows:-
My invention consists of a new method of fixing the hoops and bottoms on milk
cans especially those used on railways.
It is also applicable to other kinds of cans, drums or bottles made out of sheat
metal-where great strength is required for withstanding rough usage.
I carry out my invention by making a malleable or wrought iron or steel hoop
for the bottom of the milk can. This hoop has the inside of its upper portion made
conical and widening towards the top. The lower part of the conical portion
terminates with a rebate or ledge.
I make the bottom edge of the body of the can tapering inwards sufficiently to
fit into the conical part at the top of the hoop.
The body of the can is then driven tightly into the hoop-which it is better to
have tinned previously-until the lower edge of the can body projects a little
through the conical portion of the hoop.
This edge is then hammered outwards on to the before mentioned ledge to form &
Beam with the hoop.
By then soldering, the whole is made solid and firm and will resist great strain
when subjected to rough usage.
I fix the bottom of the can also on the said ledge-the bottom being first edged-
this edge projecting downwards and fitting against the sides of the hoop. It is
then soldered inside and out.
By this method a new bottom can be fixed in the can without taking off the
hoop.

1, SAMUEL BRASSINGTON BAMFORD, of the Firm of H. Bamford & Sons,
Uttoxeter, in the County of Stafford, Agricultural Engineers, 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:—
My invention relates to a now method of fixing the hoops and bottoms or ends of
sheet metal cans, drums and bottles requiring great strength for withstanding
rough usage, the said invention being particularly applicable to milk cans lised on
railways.
In carrying out my invention I make a malleable or wrought iron or steel hoop
for the bottom of the milk can or other vessol, the said hoop having an inwardly
projecting flange, the upper side of which is made conical to form a seat whilst the
lower side forms a rebate or ledgo. The bottom edge of the body of the can is
coned or tapered inwards sufficiently to fit into the conical seat in the hoop and the
lower edge of the body which projects below the conical seat of the hoop is
hammered outwards onto the said ledge.

page_text: The bottom of the can or the like is fitted against the said ledge and is flanged
to fit against the sides of the hoop.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which-
Figure 1 is a central section of the lower part of a milk can having the hoop and
bottoin fixed according to my invention.
Figure 2 is a sectional view of the hoop detached.
Figure 3 is a sectional view of the bottom of the body of the can adapted to fit
into the hoop; and,
Figure 4 is a sectional view shewing how the body is fixed to the hoop.
Figure 5 is n sectional view of the bottom of the can detached.
Figure 6 is a sectional elevation drawn to a smaller scale than Figures 1 to 5 of
a milk can constructed according to my invention and provided with a
spring-fastener for the lid; and,
of
Figure 7 is a plan view of the said can.
special form
Similar letters of reference indicate corresponding parts in the several figures.
a is my malleable or wrought iron or steel hoop having the conical seat baud the
ledge c, as shewn in Figure 2. d is the body of the milk can, the bottom edge of
which is coned or tapered at e, as shewn in Figure 3, so that it will fit into and
project slightly below the seat c, as shewn in Figure 4, in which figure the projecting
portion is indicated by dotted lines. f is the bottom of the can which is flanged at
its edges and adapted to fit within the ring or hoop a, as shewn in Figure 1.
In fitting the can the body is first driven tightly into the hoop which is preferably
tinned so that it will readily take solder and then the projecting portion of the body
of the can indicated by the dotted lines in Figure 4 is bent onto the ledge c, as
indicated at g in Figure 4, the turned-over edge boing preferably soldered to the
ledge c. The bottom is now introduced into the hoop so that its edges lie against
the turned-over part g of the body and solder is then applied as at A Figure 1 to cover
the joint between the conical portion e of the body and the bottom, and as at i to
secure the bottom to the hoop.
By adopting this method of fixing the bottom it is obvious that by removing the
solder at hand i the bottom can also be removed and replaced.
The spring fastening which I advantageously employ in conjunction with a milk
can constructed according to my invention is shown in Figures 6 and 7, in which.
jindicates the lid, k an abutment at one side of the neck of the can and any catch
or fastening. This catch is formed of a plate of steel or other suitable material
doubled upon itself and secured at one end to the neck of the can, the other end
being free to project over the lid to prevent the latter from lifting. In order to
pall back the free end of the catch so that the lid may be removed, a stud mis
fixed to the said free end of the said catch and projects through a hole in the neck
of the can, the other end of the said stud carrying a ring a which serves as a
handle. It is obvious that when the ring n is gulled the free end of the catch
will be pulled out of engagement with the lid so that the latter can be readily
.removed.
Although I have described my invention as applied to a milk can it is obvious
that the bottoms or ends of sheet metal cans, drums, bottles, pails and the like can
be fixed in a similar manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
.claim is :-
1. A sheet metal can, drum, bottle or the like having its bottom or end fixed in
a hoop provided with a conical seat into which the correspondingly tapered part of
the body of the vessel is fitted and with a ledge over which the extreme end of the
body is bent and having a bottom or end which is soldered within the said hoop,
-substantially as described.
2. The manufacture and use of sheet metal cans, drums, bottles and the like the

page_text: bottoms or ends of which are fixed substantially in the manner hereinbefore
described and illustrated in the accompanying drawings.
3. The combination with a milk can having the hoop and bottom fixed sub-
stantially in the manner hereinbefore described and illustrated in Figures 1 to 4 of
5 the accompanying drawings, of a catch arranged substantially as described by
reference to Figures 6 and 7 of the accompanying drawings.
