This invention relates to a new manufacture of collapsible metal tubes for
containing colours or moist pigments perfumed essences and the like and to the
mode of making such tubes, whereby a more ornamental and presentable article
can be obtained and at a reduced cost as compared with the mode of pressing up
by a hand press the process of manufacture is expedited and in lieu of using pure
tin of a heavy gauge, a cheaper compound metal of lighter gauge or what is now
known as capsule metal (that is to say, lead, covered or coated on one or both sides
with tin) can be substituted.

In carrying out this invention I make the said improved collapsible tubes in the
well known capsule making machines by first making the rigid headed cap and a
screw capsule to fit on the outside of the rigid capsule provided with flexible
flange to prevent removal and the colour or other contents from 'escaping or exuding.
I also take the rigid headed capsule and punch, puncture, or otherwise drive out the
small mouth or orifice and I emboss or otherwise embellish by the aid of suitable
punches or dies used either separately or in the capsule making machine itself the
sides or tops or both of the said collapsible tube with either plain or coloured trade
marks or other devices, thereby dispensing with the use of labels.
I sometimes embellish and form trade marks on the said tubes by applying a
thin perforated capsule over the tube showing a variety of colours “beneath and
employ coloured foil pasted or otherwise applied round the said 'tube.

A communication to me from abroad by Charles Cheswright of Hotel Simon,
Cognac in the Republic of France
The said invention relates to a new or improved manufacture of collapsible
*metal tubes such as are employed for example for containing artists colors or moist
pigments, shaving soap, perfumed essences and the like and to the mode of making
such tubes whereby a more ornamental and presentable article can be obtained
and at a much cheaper rate than by the mode of pressing up by a hand press
hitherto adopted moreover the process of manufacture is expedited and facility is
afforded for using in substitution for pure tin in the manufacture of this class of
tubes a cheaper compound metal of lighter guage that is to say lead plated or
coated with tin on one or both sides.
According to one mode of carrying out this invention I draw a collapsible tube
from a disc of lead or its alloy plated or coated with tin by the aid of a succession
of punches and dies in the well known capsule making machines to as great a
length as is practicable in those machines but in order to still further elongate the
tube I transfer it from the horizontal plungers to a second drawing machine
provided with one or more vertical plungers or punches working downwards
through dies and driven more slowly than in the ordinary capsule making machine
in order to continue the drawing in a more gradual and effectual manner whilst at
the same time facilitating the removal of the tube from the lower end of the
punch. The stroke of the punch, which is caused to reciprocate slowly by a crank
pin and connecting rod, is capable of being varied to any desired extent by
adjusting the throw of the crank pin..
The closed end of the collapsible tube is made rigid or of increased strength on
the crown as well as down a portion of the sides at the commencement of drawing
the same in the manner described with reference to capsules in the Specification
No 1103 A.D 1879. The crown is. then removed and a screw thread formed
round the rigid portion of the sides of the tube to receive a screwed capsule or
cover by preference made rigid for closing. the top of the tube so that when the
said capsule or cover is removed the tube may be readily filled from the open
mouth instead of from the opposite end as heretofore which. will be permanently
closed by folding soldering or otherwise. The said screwed capsule or cover may
be soldered to the tube or secured by a metal trade mark capsule placed over it
and pressed round the end of the tube. A perforated nipple which may be of
pure tin and provided with an external or internal screw thread is applied and
fixed by soldering screwing or otherwise over a perforation in the said screwed
capsule or cover or the nipple may be made in one with the said cover the said
nipple being closed by the usual small rigid screwed cap having an internal screw
thread or by a plug or stopper having an external thread as the case may be
screwed thereon or therein. The said nipple may protrude through an opening in
the before mentioned outside protective capsule so as to allow the contents of the
tube to be expelled in ordinary use without the tube being subjected to fraudulent
refilling. The small rigid screwed cap fitted over the nipple is by preference
formed with a flexible flange or thinner portion round its lip after the manner

page_text: described with reference to capsules in the said specification N° 1103 A.D 1879 or
it may be capsuled which capsule or the flexible flange when compressed tight
round the lower portion of the screwed nipple will effectually prevent the
possibility of removal of the cap without destroying the flexible flange or the
outer capsule placed over such cap and will also prevent the contents from escaping
or exuding by leakage.
If desired the before mentioned screwed capsule or rigid cover for closing the
end of the collapsible tube may also be made with a thin flexible portion or flange
for securing it to the body of the tube by being compressed tightly round it. In
some cases if desired the long collapsible tubes produced from a metal disc of lead
or its alloys (plated or coated with tin) by a series of punches and dies caused to
act in succession upon the metal as above described may be left with one end
closed as they come from the dies and punches of the drawing machine or machines
or they may be cut into any desired lengths of tube open at both ends in which
latter case I solder onto one end of the tube a rigid metal cap or capsule made
separately of stouter metal the said rigid cap having a screwed perforated nipple
attached thereto or formed thereon and closed by a small screwed cap or plug as
before described.
The opposite end of the said tube when filled is closed either by folding and
nipping as is well known or by soldering a disc thereon.
I embellish the sides or tops or both of the said improved collapsible tube with
either plain or coloured trade marks or other devices printed thereon thereby
dispensing with the use of labels.
Having now described and particularly ascertained the nature of the said
invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the invention secured to me by the herein before in part
recited letters Patent is:-
First. The manufacture of collapsible metal tubes from lead or its alloys plated
or coated with tin substantially in the manner and for the purposes hereinbefore
described.
Second. A collapsible metal tube suitable for containing artists colors perfumes
and the like composed of lead or its alloys plated or coated with tin made rigid or
of increased strength at one end closed at the rigid end by a separate screwed
capsule or cover having a perforated screwed nipple thereon and protected against
fraudulent refilling by an outer trade mark capsule or by a thin flexible flange
formed on the end of the capsule or cover itself pressed or folded round the tube
the opposite end of the said tube being permanently closed by a disc of metal
soldered thereon or by the usual method of folding and nipping as hereinbefore
described.
Third. The mode of manufacture of the said collapsible metal tubes from discs
of lead or its alloys plated or coated with tin by gradually drawing the same into
a tubular form by the aid of a series of punches and dies caused to act in succession
and so arranged as to leave the crown and a portion of the sides of the tubes rigid
or of greater strength than the rest as herein before described.
In witness whereof I the said Charles Edward Henry Cheswright have
hereunto set my hand and seal this seventh day of June in the year of
our Lord one thousand eight hundred and eighty three.
