Improvements in Means for Drawing Off Liquids from Tins, Cans,
and the like.
I, GIULIO CARMELO NOBILE, of The Monico, Shaftesbury Avenue, London, W.,
Manager of Restaurant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means for drawing off liquids from cans or tins and
it is designed more particularly for use in connection with the drawing off of thick
liquids such as condensed milk, puree of tomatoes, paint, varnish, and the like.
These liquids are usually contained in tins fitted with a removable lid or, in some
cases, in hermetically closed cans and my invention has for object to facilitate
the withdrawal of a quantity of such liquid from the can without removing the lid,
and to lessen, if not altogether to prevent, the deterioration of the remainder in
the can.
i
It consists essentially of a short pipe provided with a spiked end or extension
which is inserted into the can and which acts as a tap for the withdrawal of the
liquid. The pipe is provided at about the centre of its length with shoulder
securely attached thereto by soldering or otherwise and the lower half is cut away
obliquely and tapered to a point, thus forming the foot or spike of the device.
number of holes may, if desired, be perforated in the lower half of the pipe, and
in some cases I may attach a spike formed of hard metal to the tapered lower.
half to facilitate the insertion of the device in the can.
A
I may furnish two or more longitudinal ribs on this lower half, in which case
they will preferably be tapered similarly to the foot or spike.
A rubber, dermatine or other suitable washer is provided under the aforesaid
shoulder and above the ribs.
The top or delivery end of the pipe may be furnished with a lip and with a suit-
able cap, hinged or otherwise. In lieu of this cap a screw-plug or equivalent
device may be employed to exclude air, dust etc. from entering the pipe when not
in use.
When using a pipe of a narrow bore and to allow of the entrance of air into the
can so that the liquid may be poured out, I may connect a second pipe from the head
of the first and preferably diametrically opposite to the lip thereof, to the
body of the can and furnish a bush for insertion into the latter. The connection
may be made, if desired, by means of a flexible pipe, the object being as before
stated. The hole for the entrance of this bush may be punched in the can by
means of the spiked end of the draw-off device.
The pipe is made preferably of metal throughout and may be enamelled, plated
or otherwise suitably coated.

I, GUILIO CARMELO NOBILE, of The Monico, Shaftesbury Avenue, London, W.,
Manager of Restaurant, 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 means for drawing off liquids from tins or cans and
is designed more particularly for use in connection with the drawing off of thick
liquids such as condensed milk, puree of tomatoes, paint, varnish and the like.
These liquids are usually contained in tins fitted with a removable lid or, in some
cases, in hermetically closed cans and my invention has for object to facilitate
the withdrawal of a quantity of such liquid from the can without removing the lid,
and to lessen, if not altogether to prevent the deterioration of the remainder in
the can. By means of my invention I dispense with a tin opener and allow the
can to remain closed.
My invention consists essentially of a short pipe provided with a sharp spiked
end or extension which is inserted into the cam and which acts as a removable
tap for the withdrawal of liquid.
Referring to the accompanying sheet of drawings for a fuller explanation of
my invention :-
Figure 1 is a side elevation of my device for drawing off liquids and the like
from cans and tins.
Figure 2 being a rear elevation of the same.
Figure 3 shews also in elevation, a modified form of my invention.
Figure 4 shews an alternative arrangement of the fin or rib.
My device for drawing off liquids consists of a short pipe a provided with a
spiked end or extension a', which is inserted into the can, represented by the
dotted line, and which device acts as a tap for the withdrawal of liquid. The
pipe a is provided at about the centre of its length with a flange a securely
attached thereto by soldering or otherwise and the lower half is cut away obliquely
and tapered to a point, thus forming the foot or spike of the device.
A number of holes b may, if desired, be perforated in the lower half of the
pipe, and in some cases I may attach or secure a spike c of hard metal (Figure 3)
to the tapered lower half a¹ to facilitate the insertion of the device in the can.
I may furnish one, two or more longitudinal ribs d on this lower half a', in
which case it or they will preferably be tapered, similarly to the foot or spike.
A rubber, dermatine or other suitable washer e is provided under the aforesaid
flange a and above the ribs d.
The top or delivery end of the pipe may be furnished with a lip f and with a
suitable flap f, hinged or otherwise and which may be provided on its under side
with a washer of rubber or other suitable material. In lieu of this flap a screw-
plug or equivalent device may be employed to exclude air, dust etc. from enter-
ing the pipe when not in use and in this case the upper portion a of the pipe is
made straight and not as drawn.
When using a pipe of a narrow bore and to allow of the entrance of air into the
can so that the liquid may be poured out, I may provide a second pipe g leading
from the head of the first to the body of the can, as shewn in dotted lines
Figure 3.
Or, in lieu of the pipe shewn in dotted lines on Figure 3, I may secure a detach-
able pipe or flexible tube to the upper portion a of the pipe a a' and furnish the
other free end of this flexible pipe with a suitable bush for insertion into the

page_text: can.
The hole for this bush may be first formed in the can by means of
the spike.
This auxiliary pipe will then act to admit air into the can, but the previous
modification is a simpler arrangement and has the advantage of being more
compact.
The pipe a a¹ is made preferably of metal throughout and may be enamelled,
plated or otherwise suitably coated.
The objects of the ribs or fins d which are provided with cutting edges on their
under side are to facilitate insertion of the device into the can and to secure the
same therein by partly revolving the pipe a.
The ribs will then take a position
other than immediately under the holes or slots formed thereby. The upper side
of the flange a may be marked with a suitable mark so as to facilitate the with-.
drawal of the device from the tin or can indicating the position of the fins or
ribs, and, consequently, when these are immediately under their respective holes
or slots.
In lieu of pouring out the contents of the tin through this device the lid or
flap may be opened and the liquid or powder contained in the can may be with-
drawn by means of a suitable spoon.
Knobs or handles h may be provided on the upper part of the pipe to facilitate
the insertion of its lower portion into the can and also the turning of the same.
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. A device for insertion into a can or the like and for drawing off liquids there-
from, consisting essentially of a capped head and a lower tapered or cut away por-
tion, separated by a flange.
2. A device for drawing off liquids, consisting of a tube furnished with a cut
away lower portion or spiked extension from its lower tapered portion, a flange
or shoulder at about the centre of its length and a communication tube extending
from the top portion of said device to its lower end or furnished with a bush for
insertion into the can, substantially as described.
3. In a pipe device for drawing off liquids from cans, the combination of the
upper portion of a pipe having a flap or plug, of a lower tapered or cut-away por-
tion, and of a flange at about the centre of the length of the pipe device, substan-
tially as described.
4. In a pipe device for drawing off liquids from cang the combination of the
upper portion of a pipe fitted with a flap or plug, of a lower tapered or cut away
portion having one or more longitudinal fins or ribs thereon and of a flange at
about the centre of the length of the pipe, said flange being provided underneath
with a washer or ring of soft or elastic material, substantially as described.
5. In a pipe device for drawing off liquids, the combination of the upper portion
of a pipe fitted with a flap or lid and with a tube communicating with the lower
portion of the same or communicating direct with the can and having a bush for
insertion therein, and of a lower tapered or cut away portion, having, if desired,
a spiked extension, and of a flange at about the centre of the length of said
pipe and provided underneath with a washer or ring of elastic material, substan-
tially as described.
