Improvements in Apparatus for Capsuling Bottles and other
like Vessels.
I CHARLES CHESWRIGHT of Leith Villa Parkhurst Road in the County of
Middlesex Manufacturer do hereby declare the nature of said invention for
"IMPROVEMENTS IN APPARATUS FOR CAPSULING BOTTLES AND OTHER LIKE
VESSELS to be as follows:-
This Invention relates to improvements in what are known as hydraulic
capsuling machines for fixing capsules over the mouth or stoppered portion of
a bottle or other similar vessel and has for its chief object increasing the durability
of the elastic or rubber chambers employed in such machines by obviating the
destructive strain or tearing action exerted upon the external holding flange
hitherto formed round the mouth of the elastic chamber for the purpose of
enabling it to be gripped or held firmly in an annular groove surrounding the
mouth of the metal chamber, within which the said elastic chamber is contained,
in order to form a joint which shall be fluid tight under considerable pressure.
Now my present invention consists of a peculiar construction of the front part
of the elastic chamber whereby the necessity for gripping or holding it fixed at
that part round the mouth of the metal chamber is obviated, the elastic chamber
being left perfectly free at that part and formed with an reverted lip tapering in
thickness towards its inner edge and acting as a cup-leather packing by expanding
against the interior of the metal chamber when the fluid pressure is applied but
fitting the said chamber easily when the pressure is taken off, thus enabling the
elastic chamber which constitutes its own fluid tight joint to be readily removed
and replaced when required. The inner end of the improved elastic chamber may
also be left free or disconnected from the metal chamber in which case it is
prevented from being expelled from the metal chamber by an internally flanged
metal ring screwed onto the mouth of that chamber without in any way gripping
the rubber. Or if preferred the inner end of the said elastic chamber may be
screwed by a nut and screw or by a screw alone to the back of the metal chamber
but in all cases the front or entering end is left free. The before mentioned
tapered lip constituting a cup-leather packing in one with the elastic chamber may
be formed round an elastic tube in lieu of round a cup-shaped chamber said
tube being by preference made with a slightly conical or tapered bore to receive
the neck of the bottle and closed at its inner end by a metal cap or cover which

page_text: enables it to be there secured to the inner end of the enclosing metal chamber.
When intended for champagne capsuling or where extra large capsules are used I
make the said improved elastic chambers of corresponding dimensions and I form
therein longitudinal grooves for absorbing the pleats of superfluous metal produced
in the act of compressing the capsule as is well understood. In some cases I fit
over the end of the elastic chamber an external metal or other rigid cap which
covers and protects from pressure the extreme end and more or less of the side of
the said elastic chamber whilst at the same time admitting of the pressure being
concentrated upon a greater or less area of the front portion of such elastic
chamber according to the depth of such rigid cap thus enabling the pressure to be
confined to that part of the neck or mouth of the vessel where it is chiefly required.
I also combine when requisite with my aforesaid improved elastic chamber an
internal rigid metal cap or thimble for protecting the end of the soft metal capsule
on the bottle from pressure as is well understood in reference to this class of
capsuling machines The general arrangement and construction of the machine in
which my said improved elastic chambers may be employed, may be varied more
or less provided these essential parts be retained, namely a rigid metal chamber for
receiving the elastic chamber such rigid chamber being shaped to receive the
reverted tapered lip or cup-leather ring formed round the mouth of the elastic
chamber, a cylinder opening into the side or end of the rigid chamber provided
with a piston or plunger working through a stuffing box and actuated through
suitable connections by hand or by foot, a filler and cock for supplying the said
chamber with any suitable liquid such as water, or, which I prefer, glycerine, as
having a less injurious action on the rubber and not being liable to congeal; and
finally a discharge cock for the escape of the liquid from the rigid chamber when
required.
I sometimes form longitudinal flutings or small grooves round the inside of the
before mentioned improved elastic chamber in order to take up the superfluous
metal of the capsule in the form of fine corrugations which I may afterwards
ornament by applying color to the ridges thereof.

Improvements in Apparatus for Capsuling Bottles and other
like Vessels.
I CHARLES CHESWRIGHT of Leith Villa, Parkhurst Road in the County of
Middlesex, Manufacturer do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
-
This Invention relates to the elastic or rubber chambers employed in what are
known as Hydraulic capsuling machines of the kind described in the specification
to Letters Patent granted to James Paterson bearing date the 28th of November
A.D. 1871 N° 3213 for fixing a soft metal or other like capsule over the neck or
stoppered portion of a bottle or similar receptacle and has for its chief object
increasing the durability of the said elastic or rubber chainber by obviating the
destructive strain or tearing action exerted upon the external holding flange hitherto
provided round the mouth of that chamber in order to form a fluid tight joint by
gripping or holding such flange firmly in an annular groove surrounding the mouth
of the metal chamber.
Now my invention consists of a peculiar construction of the front part of the
elastic chamber whereby the necessity for fixing it round the mouth of the metal
chamber is obviated it being so constructed as to admit of its being left free at the
front part whilst still forming a fluid tight joint with the metal chamber. For this
purpose I form my improved elastic chamber with a reverted lip by preference
tapering in thickness towards the inner edge so as to act as a cup-leather packing
by expanding against the interior of the metal chamber when the fluid pressure is
applied whilst greater facility is afforded for the removal and replacement of the
elastic chamber when required.
Figure 1 of the accompanying drawings is a longitudinal vertical section of a
portion of a Hydraulic capsuling machine provided with my improved "cup-leather"
elastic chamber.
Figure 2 is a corresponding front elevation of the same.
Figure 3 is a vertical sectional detail on a larger scale of my improved cup-leather
elastic chamber detached and,
Figure 4 is a view similar to figure 1 but showing the inner end of the improved
elastic chamber secured to the inner end of the metallic chamber in lieu of being
left free at that part as in figure 1.
A is the elastic chamber of rubber or other suitable material for receiving the
neck of the bottle or other receptacle round or over which a capsule is to be
applied. B is the metallic chamber within which the elastic chamber is placed
freely. C is a portion of the plunger for producing by its descent in the cylindrical
or other shaped chamber D the requisite fluid pressure round the exterior of the
elastic chamber as is well understood. E is a filling cup and stop cock for charging
the chambers B and D and F is a discharge cock and pipe for emptying the said
chambers when requisite. a is a reverted lip by preference tapered towards its
inner edge as shown so as to constitute a "cup-leather" packing said reverted lip

page_text: being formed round the open mouth of the elastic chamber and fitting accurately,
but without being fixed thereto, the interior of the front portion of the metallic
chamber. G is an internally flanged inetal ring screwed or otherwise fixed onto the
front of the metal chamber B so as to protect the front of the clastic chamber A
and prevent it from being forced out by the internal pressure.
In some cases I may combine with my improved elastic chamber a rigid metal
cap or thimble fitted over the exterior of the inner end of the said chamber or
inserted into the interior thereof for the purpose of protecting from pressure the
end of the soft metal capsule covering the protruding portion of the cork when
capsuling champagne bottles as is well understood in reference to this class of
capsuling machine. If desired longitudinal flutings or narrow grooves may be
formed round the inside of the elastic chamber in order to take up the superfluous
metal of the capsule in the form of fine corrugations which may be afterwards
ornamented by applying color to the ridges thereof. The plunger C which may
work through the usual stuffing box and gland may be actuated by the foot of the
operator by an arrangement similar to that described in the said former specifi-
cation or by side rods connecting a cross head on the top of the plunger with a
foot lever below or by any other well known mechanical arrangement suitable for
the purpose.
I prefer to employ glycerine as the liquid medium for applying the
pressure as having a less injurious action on the rubber than water and not being
liable to congeal.
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
In apparatus of the class referred to for applying capsules to bottles or other like
receptacles the use of an clastic chamber formed with a reverted lip which con-
stitutes a "cup-leather packing by being expanded outwards against the inner
sides of the metal chamber by the fluid pressure therein substantially as specified.
