PROVISIONAL SPECIFICATION.
Improvements in Canister Tops.
I, JOHN WATERS, of 46, Bordesley Street, in the City of Birmingham, Grocers'
Outfitter, do hereby declare the nature of this invention to be as follows:-
This invention applies to the manufacture of the tops, shoulders, or necks of
canisters used by grocers and tea dealers for the storing of tea, coffee, and the like.
Hitherto these have been made in two parts seamed or grooved together, & after-
wards put in a machine to form the bead. which forms the finish to connect it to
the body of the canister, the opening or mouth of the top, neck, or shoulder being
cut out with shears.
My invention consists in forming the top, neck, or shoulder seamless by placing
the metal in a machine which forms it into the required curved shape with the
moulding on the edge for forming the bead and the mouth or opening cleanly cut
out in a perfectly true curve, circle, or other required shape, thus leaving a piece
of metal suitable for immediate use in the manufacture of a similar article of a
smaller size. I can produce these tops, necks, or shoulders of any variety of
shapes to suit the various shapes of canisters, & manufacture a much neater article
with less labor & cost. I make no claim for any specially constructed machine
for my purpose the object being the construction of the canister neck without seam
or waste of material."

I, JOIN WATERS, of 46, Bordesley Street, in the City of Birmingham, Grocers'
Outfitter, 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: -
This invention applies to the manufacture of the tops shoulders or necks of
canisters such as are used by grocers & teadealers for the storing of tea, coffee,
and other groceries.
Hitherto these have been made in two parts seamed or grooved together and
afterwards put in a machine to construct the bead upon it which forms the finish
to connect it to the body of the canister, the opening or mouth at the top of the
neck or shoulder being cut out with shears to the circular or other desired shape
which it is difficult to do with perfect accuracy.

page_text: My invention consists in forming the top neck, or shoulder of the canister
seamless by placing the metal in a machine which forms it into the required curved
shape with the moulding on its edge for forming the bead, for connecting it to
the body of the canister and which also cleanly cuts out the mouth or opening in a
perfectly true curve, circular or other required shape, thus leaving a piece of metal
suitable for immediate use in the manufacture by the same process of a similar
article of a smaller size.
The accompanying sheet of drawings illustrate my invention.
Fig. 1 shews a circular sheet of metal from which to produce a top for a circular
bodied canister.
Fig. 2 is a sectional view of the metal when formed into the desired shape.
And Fig. 3 is a perspective view of the completed article.
The sheet of metal Fig. 1 is placed in a machine which forms the metal into the
desired curved shape (such as the sectional outline Fig. 2) with the moulding (a)
on its edge for forming the bead for connecting the neck (b) to the body of the
canister. At the same process the portion (c) within the dotted lines, Fig. 1, is
cleanly cut out at once leaving the perfectly circular opening (d) forming the
mouth of the canister and leaving a perfectly circular sheet of metal (c) suitable
for making another neck for a canister of a smaller size.
By constructing canister tops as above described I can produce a much neater
article than by the usual process and do so with less labour and less cost than
hitherto.
I can produce these canister tops necks or shoulders of any variety of shapes to
suit the various shapes of canister bodies.
I do not claim any special machine to effect my purpose, which is, to construct
canister necks without seam and without waste of material.
Having now particularly described and ascertained the nature of my said
invention and in. what manner the same is to be performed, I declare that what
I claim is;-
(1) The manufacture of the tops shoulders or necks of canisters used for storing
tea coffee and other groceries in one seamless piece and forming the mouth or
opening to the tops the exact required outline at the same process.
Dated this 16th day of May 1898.
