PROVISIONAL SPECIFICATION.
Improvements in the Method of Filling Tins or Cans with Jellies,
Condensed Milk, and other Semi-fluid Substances.
I, FREDERICK WILLIAM FEAVER, of Lawrence Road, South Norwood, in the
County of Surrey, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the method of filling tins or cans with
jellies, meat extracts, condensed milk, paint and other semi-fluid substances.
Hitherto in filling tins or cans with semi-fluid substances, such as above named, it
has been necessary to form a large hole in one end of the tin or can through which
the material has been passed by means of a funnel or tap. When the tin is filled, a
disc or cap has to be soldered over the said hole and in this disc or cap a small hole
had to be left to allow of the escape of air during the operation of soldering on the
disc or cap, which small hole had subsequently to be closed by being tipped with
solder.
Now the object of my invention is to obviate the necessity of using a cap or disc
as heretofore.
In carrying out my invention I merely form in one end (or other part) of the tin
or can, a small hole only, and I introduce the meat extract, condensed milk or other
semi-fluid substance into the tin or can through the said small hole by employing
pressure. In practice I find it advantageous to employ a cylinder and piston, the
capacity of the cylinder being such that each stroke of the piston will deliver into the
tin the required amount to fill the same. Or I can employ any other suitable meter
which will allow of a fixed quantity of the material being delivered and forced into
the tin or can at each operation.
The tin or can having been thus filled all that remains to be done is to close the
small filling hole by tipping it with solder.

Improvements in the Method of Filling Tins or Cans with Jellies,
Condensed Milk, and other Semi-fluid Substances.
I, FREDERICK WILLIAM FEAVER, of Lawrence Road, South Norwood, in the County
of Surrey, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in the method of filling tins or cans with
jellies, meat extracts, condensed milk, paint and other semi-fluid substances.
Hitherto in filling tins or cans with semi-fluid substances, such as above named,
it has been necessary to form a large hole in one end of the tin or can through
which the material has been passed by means of a funnel or tap. When the tin is
filled, a disc or cap has to be soldered over the said hole, and in this disc or cap a
small hole had to be left to allow of the escape of air during the operation of
soldering on the disc or cap, which small hole had subsequently to be closed by being
tipped with solder.
Now the object of my invention is to obviate the necessity of using a cap or disc
as heretofore.

semi-fluid substance into the tin or can through the said small hole by employing

capacity of the cylinder being such that each stroke of the piston will deliver into the
tin the required amount to fill the same. Or I can employ any other suitable meter
which will allow of a fixed quantity of the material being delivered and forced into
the tin or can at each operation.
In the accompanying drawing I have illustrated by a sectional elevation a form of
apparatus suitable for carrying out my invention.
In this figure a indicates a cylinder, b a reservoir surrounding the same and co-
municating with the interior thereof by openings such as c, the capacity of that portion
of the said cylinder below the opening c corresponding with the quantity of substance
required to fill a tin or can.
d is a piston which in the drawing is shewn as adapted to be operated by a
screw e.
f is a filling nozzle at the bottom of the cylinder which is advantageously provided
with a cock y for opening and closing the said nozzle.
h indicates a tin which is to be filled, the said tin being provided with a small
hole i only.
jis a spring platform upon which the tins are placed.
The operation is as follows:-Assuming the parts of the apparatus to be in the
position shewn, the reservoir to be charged with the semi-fluid substance and a tin h
to be pressed upon the spring platform j so as to bring its small hole i over the filling
nozzle f; if now the piston is lowered the required quantity of semi-fluid substance
will be forced into the tin through the nozzle f. The tin or can is then removed
and the small filling hole i closed by tipping it with solder.
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. The method herein described of filling tins or cans with jelly, condensed milk
or other semi-fluid substances such method consisting in introducing a measured
quantity of the semi-fluid substance into the tin or can through a small hole therein
by means of pressure, for the purpose specified.
2. The use in filling tins or cans with semi-fluid substances, of the apparatus herein-
before described and illustrated in the accompanying drawing.
