page_text: I, FREDERICK WILLIAM KNOWLES, of Ivy House, Thornhill Lees, near Dewsbury,
in the County of York, Manager of Glass Works, do hereby declare the nature
of this invention to be as follows:-
1
This invention has reference to stoppers for closing bottles. In constructing a
stopper according to my invention I form the shank of the stopper somewhat
tapered and at the end of the shank 1 form a small ledge or projection. In con-
junction with this stopper I employ a ring of cork or other similar expansible
substance, of such size as to grip the shank of the stopper. The ledge or annular
projection at the bottom of the shank is of such size or width as to allow the
cork ring to be slipped thereover with pressure when wet, but the said ledge is
sufficiently wide to prevent the ring working off again.
In order to prevent movement of the stopper independent of the cork ring, I
mould or otherwise form two small points or projections at diametrically opposite
positions on the shank of the stopper which, when the cork ring is placed in posi-
tion engage said ring and ensure due movement thereof with the stopper.
The stopper may be constructed of glass or other material and may be moulded
cast, or formed in any suitable manner.

In order to prevent movement of the stopper independent of the cork ring c I
mould or otherwise form two small points or projections dat diametrically oppo-
site positions on the shank of the stopper which when the cork ring c is placed in
position engage said ring and ensure due movement thereof with the stopper.
The stopper may be constructed of glass or other material and may be moulded,
last, or formed in any suitable manner.
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;-
The combination with a stopper for closing bottles, having a tapered shank a,
of a ring constructed of cork or other suitable expansible material or substance,
together with a flange band pegs for keeping same in position, all arranged
substantially as shewn and described.
