PROVISIONAL SPECIFICATION.
Improvements in Means Employed in Capsuling Bottles.
I, DAVID PATERSON of 8 Mathew's Park Avenue, Stratford, in the County of
Essex, Engineer, do hereby declare the nature of this invention to be as
follows:-
.
The invention relates to that class of capsuling apparatus in which an elastic
chamber made of vulcanized india rubber is employed of capacity to receive the
bottle neck with the capsule thereon and which is compressed around said capsule
generally by hydraulic power to secure the same on the bottle neck.
Heretofore such elastic chamber has been provided with a metallic disc or cup in
the crown to resist the pressure at such point for the purpose of preventing the
compression of the capsule around the cork.
This disc or cup has been fixed in position by a screw threaded pin or stud
thereon passing through a hole in the crown of the elastic chamber and a nut on
the outer part of such pin or stud acting against a washer on the outer side of the
crown of said elastic chamber.
With the above construction of elastic chamber considerable difficulty is
experienced from leakage of the water through the crown thereof, in addition to
which on account of the metal disc or cup being on the inner face of the said
chamber the bottle is sometimes broken.
Now according to my present invention I obviate these difficulties by embedding
a plain disc or cup within the substance of the rubber forming the elastic chamber.
By this means l'obtain a rubber cushion between the said disc or cup and the
bottle neck and cork and I avoid any perforation of the crown of said chamber.
The said disc or cup is preferably formed of metal but other sufficiently strong
and suitable material may be employed.

Improvements in Means Employed in Capsuning Duties
I, DAVID PATERSON, of 8 Mathew's Park Avenue, Stratford, in the County of
Essex, Engineer, 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 :-
The invention relates to that class of capsuling apparatus in which an elastic
chamber made of vulcanized india rubber is employed of capacity to receive the
bottle neck with the capsule thereon and which is compressed around said capsule
generally by hydraulic power to secure the latter on the bottle neck.
Heretofore such elastic chamber has been provided with a metallic disc or cup in

page_text: the crown to resist the pressure at such point for the purpose of preventing the
compression of the capsule around the cork.
This disc or cup has been fixed in position by a screw threaded pin or stud
thereon passing through a hole in the crown of the elastic chamber and a nut on
the outer part of such pin or stud acting against a washer on the outer side of the
crown of said elastic chamber.
With the above construction of elastic chamber considerable difficulty is
experienced from leakage of the water through the crown thereof in addition
to which on account of the metal disc or cup being on the inner face of the said
chamber the bottle is sometimes broken.
Now according to my present invention I obviate these difficulties by embedding
a plain disc or cup within the substance of the rubber forming the elastic
chamber.
By this means I can obtain a rubber cushion between the said disc or cup and
the bottle neck and cork and I avoid any perforation of the crown of said chamber.
The said disc or cup is preferably formed of metal but other sufficiently strong and
suitable material may be employed..
My invention is illustrated in the accompanying drawings in which
Fig. 1 is a vertical section of one form of my improved elastic chamber for use
with capsuling apparatus.
Fig. 2 is a cross section and Fig. 3 a plan of the cup imbedded within the material
at the head of said chamber and
Fig. 4 is a vertical section representing a modification.
Referring to Figures 1, 2, 3, a is the rubber body of the said chamber and b is a
metal cup imbedded within the head of the same.
Instead however of employing a cup shaped piece b a plain disc may in some
cases be employed.
The method of constructing such rubber body and of inserting the cup or disc
therein will be readily understood by india rubber manufacturers and therefore
needs no description here.
In the modification represented at Fig. 4. the flange alone of the cup 6 is
embedded within the rubber body of the chamber whilst the head or disc of said
cup is against the under surface of the rubber body and not covered with rubber
on its lower surface. A plain disc might in like manner have its edges alone
embedded within the rubber body.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved elastic chamber to be used in capsuling machines substantially
as herein set forth and for the purpose stated.
2. In elastic chambers for compressing a capsule around a bottle neck in a
capsuling machine the manufacture of the same with a cup shaped piece or disc of
metal or other hard material embedded either partly or entirely within the
substance of the head thereof substantially as herein set forth and for the purpose
stated.
