CHARLES EDWARD HENRY CHESWRIGHT' of Leith Villa Parkhurst Road in the
County of Middlesex IMPROVEMENTS IN THE MANUFACTURE OF CAPSULES FOR
BOTTLES AND OTHER LIKE RECEPTACLES A communication to me from abroad

This invention relates more particularly to that class of champagne capsules in
which the tops are more or less cut away perforated or made with lateral openings
or spaces round them in order to afford ready facility for their being twisted or
wrenched off by hand when opening the bottle and consists in so forming by
embossing or otherwise fluting or corrugating into, a species of wire by compression,
the connecting parts or branches of the said capsules whereby such connecting
parts whilst being much slighter in appearance than heretofore and in fact hardly
visible, are nevertheless as strong if not stronger than the connecting parts in the
usual manufacture of this class of capsule made from a much heavier gauge of
metal-I am thus enabled to use a lighter gauge and to effect a considerable saving
in the weight of metal employed in the manufacture of the class of capsules before
referred to whilst the general appearance of the capsule itself is greatly improved.

CHARLES EDWARD HENRY CHESWRIGHT of Leith Villa Parkhurst Road in the
County of Middlesex ." IMPROVEMENTS IN THE MANUFACTURE OF CAPSULES FOR
BOTTLES AND OTHER LIKE RECEPTACLES." A communication to me from abroad by
Charles Cheswright of Hotel Simon, Cognac in the Republic of France.
The said invention relates more particularly to that class of champagne or other
capsules in which the tops or upper portions are more or less cut away perforated
or made with lateral openings or spaces round them in order to afford ready facility
for the upper part of the capsule being twisted or wrenched off by hand so as to
effectually destroy the capsule before opening the bottle and thereby prevent the
fraudulent use of the same capsule a second time and consists in so compressing by.
.fluting corrugating folding or doubling in a longitudinal direction by the aid of
suitable dies the hitherto Hat connecting parts or branches of the said capsules as
that they shall be more or less fluted corrugated or rounded or present the
appearance of a species of wire whereby such connecting' parts whilst being much
-slighter in appearance than heretofore are nevertheless as strong if not stronger
than the connecting parts in the usual manufacture of this class of capsule.made
from a much heavier guage of metal. I am, thus enabled to use a lighter, guage
and consequently to effect a considerable saving in the weight of metal employed
in the manufacture of the class of capsules before referred to whilst the general
appearance of the capsule itself is greatly improved.
And in order that the said invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the explanatory sheet of drawings hereunto annexed the same
letters of reference indicating corresponding parts in all the corresponding figures.
Figure 1 is an elevation of a champagne capsule of the class previously
'mentioned before being treated according to the present invention.irad
Figure 2 is an elevation of the improved capsule wherein the connecting parts
.strips or branches between the lateral openings are compressed, fluted, corrugated
rounded folded or doubled in a longitudinal direction so as to present a much
islighter and neater appearance without their strength being in any way impaired.
such
a is the body of the capsule the top or that part, thereof. which is above, the
lateral openings or spaces bb may either be left plain as in Figure 1 or be fluted
or corrugated as is well understood round the side as shown in figure
'corrugations' extending or not as preferred to the portion of the body beneath the
lateral openings. cc are the intermediate branches or connecting strips shown
flat in Figure 1 and corrugated folded or compressed in Figure 2.

Figure 3 is a full sized plan of a tool which I 'employ in carrying out the said
invention.

Figure 4 is a cross section taken' along the line 12 in Figure 3 and Figure 5
represents a pair of compressing dies in their closed position...
The tool which has been found to answer well in practice consists of a convenient
support or bracket d capable of being secured in any suitable manner to a work
'table or bench, this bracket carries the fulcra of two hand levers ee and has fitted
thereto by a nut or otherwise. between the said fulcra a mandrelf tapered" to
correspond to the taper of the capsule. The outer end of this mandrel (shown in.
cross section at figure 4) is cut away partly or flattened on one side and carries a
stationary ping also slightly tapering towards its outer end to facilitate the
withdrawal of the finished capsule. hh are two compressing corrugating fluting

page_text: folding or doubling dies mounted on the levers e so as when closed together (see
detail Figure 5) they shall meet accurately on opposite sides of the intervening
pin g and fold or compress the flat strips c (Figure 1) round the said pin thereby
imparting to the said strips the desired folded or corrugated form. The dies are
then separated by opening out the levers e and the capsule is pushed off by the
discharger i and again replaced so as to bring another strip over the pin when the
operations are repeated until all the connecting strips have been operated upon.
Lateral channels or grooves k k are formed in the sides of the mandrel to afford
room for the corrugated strips c' c¹ (6gure 2) as they are formed. It is obvious
that the shape of the pin g and of the acting faces of the two dies h h may be
varied according to the form of corrugation or fold to be imparted to the strips c c.
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 hereinbefore in part
recited letters patent is :-
The manufacture and use of capsules for bottles and other like receptacles
wherein the connecting parts or branches between the lateral openings in such
capsules are fluted corrugated rounded doubled or folded longitudinally so as to
reduce their width thereby presenting a neater appearance whilst adding to their
strength and enabling a lighter guage of metal to be employed in this class of
capsules than has heretofore been attainable.
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.
