PROVISIONAL SPECIFICATION left by the said Charles Cheswright at the
Office of the Commissioners of Patents on the 19th February 1879.
CHARLES CHESWRIGHT, of Parkhurst Road, in the County of Middlesex.
IMPROVEMENTS IN THE MANUFACTURE OF CAPSULES FOR BOTTLES AND OTHER
LIKE RECEPTACLES, AND IN THE APPARATUS EMPLOYED THEREIN.”
L
My Invention relates, 1st, to capsules intended more particularly to be used for
champagne bottles and bottles of similar shape for containing beer or other liquids,
and has for its object improving the appearance of the capsule; and at the same
time giving greater prominence to the trademark.
In carrying out this part of my Invention I make the capsule at its upper part-
in the form of a truncated cone fluted or corrugated in any suitable direction,
leaving the upper end flat for the reception of the trade mark.
In constructing capsules according to my Invention I first prepare a plain capsule
in the ordinary manner, and then by means of a punch and dies I impart to the
said capsule the required form.
My Invention relates, secondly, to improvements in apparatus for manufacturing
capsules, and consists in the use of an expanding and collapsible mould or matrix
composed of segments of metal or any other suitable rigid material acted upon by
springs either operating on each segment separately or surrounding the whole series
of segments so as to be capable of yielding or adjustment to suit the shape of the
capsule to be prepared. I also propose to employ a spring die capable of yielding
under impact or of adjustment so as to produce variegated designs for trade marks
not otherwise attainable..

CHARLES CHESWRIGHT, of Parkhurst Road, in the County of Middlesex.
"IMPROVEMENTS IN THE MANUFACTURE OF CAPSULES FOR BOTTLES AND OTHER
LIKE RECEPTACLES, AND IN THE APPARATUS EMPLOYED THEREIN.”
My said Invention relates, first, to capsules intended more particularly to be used
for champagne bottles and bottles of similar shape for containing beer or other
liquids, and has for its object improving the appearance of the capsule, and at the
same time giving greater prominence to the trademark.
In carrying out this part of my Invention I make the capsule at its upper part
in the form of a truncated cone fluted or corrugated in any suitable direction,
leaving the upper end flat for the reception of the trade mark.
In constructing capsules according to my Invention I first prepare a plain cap-
sule in the ordinary manner, and then by means of a punch and dies I impart to the
said capsule the required form.
My said Invention relates, secondly, to improvements in apparatus for manu-
facturing capsules, and consists in the use of an expanding and collapsible mould or
matrix composed of segments of metal or any other suitable rigid material acted upon
by springs either operating on each segment separately or surrounding the whole
series of segments so as to be capable of yielding or adjustment to suit the shape of
the capsule to be prepared. also may employ a spring die capable of yielding under
impact or of adjustment so as to produce variegated designs for trade marks not
otherwise attainable.
And in order that my said Invention may be fully understood, I shall no proceed
more particularly to describe the same, and for that purpose shall refer to the
several Figures on the annexed Sheet of Drawings, the same letters of reference
indicating corresponding parts in all the Figures.
Figure 1 of my Drawings represents a side elevation of a capsule constructed
according to the first part of my said Invention; Figure 2 is a side elevation of a
punch or male die and section of a matrix for carrying out the same; and Figure 3
is a plan of the matrix; Figures 4 and 5 are respectively a vertical and horizontal
section of a mould or matrix constructed according to the second part of my
Invention; and Figure 6 is a sectional elevation of the yielding die hereinbefore
referred to.
Referring to the first part of my Invention, I make the capsule A, Figure 1, at its
upper part a in the form of a truncated cone fluted or corrugated either vertically,
as shewn, or in any other suitable direction, leaving the upper end b flat for the
reception of the trade mark. In the manufacture of these capsules I first prepare a
plain capsule in the ordinary manner and then by means of a punch or male die C
and a matrix D, Figures 2 and 3, I impart to the capsule the required form, viz.,
the form shewn in Figure 1 in the example illustrated. Where (very deep im-
pressions are required I may employ a punch composed of india rubber, which will
expand on impact, or I may form the punch of metal or other suitable material, and
construct it hollow in the manner hereinafter described under the second head of
my Invention, and employ, in addition to the lower die, lateral dies which will be
caused to protrude by the descent of the lower die, and thus produce an impression
of the requisite depth.
The second part of my said Invention, which is illustrated more particularly in
Figures 4 and 5, has for its object facilitating the production of capsules of peculiar
shapes by enabling them to be readily removed from the mould in which they are
formed or impressed. For this purpose I employ a matrix composed of seg-
ments E, E, of metal or any other suitable rigid material, which may be surrounded
by another tube in segments F, F, of elastic material in its turn enclosed in a ring G.

page_text: When the capsule is formed it may be released from its mould by removing the
ring G, and thus admitting of the separation of the segments F, F, and E, E. The
seginents F, F, act as springs, but springs of other forms may be substituted
therefor or employed in addition thereto. In lieu of making the india rubber ring
in segments it may be simply divided at one point, as will be well understood. -
Means may be provided for preventing the separation of the segments beyond
certain limits. I may, in some cases, employ a spring die as shewn in Figure 6,
the die proper H being fitted in a holder I, and acted upon by a spring K, the
tension of which may be regulated by the act of adjusting a screw L.
Having now described and particularly ascertained the nature of my 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 hereinbefore in part recited
Letters Patent is,―
First. Constructing capsules, substantially in the manner and by the means
hereinbefore described and illustrated by Figures 1, 2, and 3 of my Drawings.
Second. The employment in the manufacture of capsules of apparatus constructed
substantially in the manner herein before described, and illustrated in Figures 4
and 5 and Figure 6 of my Drawings.
In witness whereof, I, the said Charles Cheswright, have to this my Specifica-
tion set my band and seal, this Fourteenth day of August, One thousand
eight hundred and seventy nine.
