Improvements in Stoppering Bottles and Vessels.
I ARTHUR SPEAR TANNER of 39 Bridge Street, Mile End in the County of Middlesex
Sign & Glass Writer do hereby declare the nature of this invention to be as
follows:-
This Invention has for its object Improvements in stoppering Bottles & Vessels.
I make the inside of the mouth of the Bottle or Vessel cylindrical with one or more
nibs projecting inwards of Glass, Metal, earthenware or other suitable material.
With this Bottle or Vessel 1 imploy a stopper made of the same or any suitable material
with a centeral plug and head or cap of a convenent size, on the underside of the head
there is an undercut groove in which I lodge a ring of Cork or other suitablo material,
the plug of the Stopper has one or more projections at its lower end extending round
the plug the upper edge of which is inclined to the axis of the stopper, and between
each projection is a vertical groove to correspond with the nibs inside the mouth of
the Bottle or Vessel, when the Stopper is inserted; the upper parts of these projections
on the plug of the Stopper are of a spiral or incline form thus forming a spiral or
inclined rebate. When the stopper is inserted and slightly turned the undersides of
the nibs inside the mouth of the Bottle or Vessel bear upon the lowest parts of the
inclined upper edges of the projections on the Stopper, and on further turning the
stopper the same is drawn into the Bottle or Vessel and closing the Cork or other
ring inserted in the groove on the underside of the cap on the rim of the neck of the
Bottle or Vessell thus making the same airtight.
In some cases the groove may be dispensed with, and in Glass Bottles I sometimes
grind the rim of the Bottle and the underside of the Cap of the stopper to be airtight
when in contact thus rendering the use of Cork or other rings unnecessary.

page_text: I ARTHUR SPEAR TANNER 39 Bridge Street, Mile End in the county of Middlesex,
Sign and Glass Writer 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 has for its object improvements in stoppering Bottles and similar
vessels, also Drums or Cans and casks which the manufacture of the same is facilitated
and is shewn in Figs. 1 and 2 on drawings hereunto annexed.
By the first arrangement shewn in Fig. 1 and which is applicable to Glass or
other kinds of Bottles, Jars or other similar vessels, I make the mouth of the vessel
cylindrical inside and having one or more nibs projecting inwards of such length and
thickness as would givo sufficient strength when formed of the material of the vessel
itself or these nibs may be of any suitable metal and inserted in the neck of the
vessel during the process of manufacturo, into the mouth of the vessel so formed I fit
a plug or stopper (1) made of the same material as the vessel or other suitable materials,
the lower end of the shank of the plug is of about the diameter of the inside of the
mouth of the vessel so as to turn freely in it, the upper end of the shank being reduced
in diameter so as to allow it to clear the nibs in the mouth of the vessel, in the lower
or enlarged part of the shank one or more vertical grooves corresponding with the
nibs inside the mouth of the vessel are made, and the upper part or edge of this part
of the shank of the stopper is slightly inclined between each of the vertical grooves in
the same direction; and on the underside of the head of the plug a groove is made
into which I lodge a ring or washer of cork or other suitable material.
In some cases where it would be desirable to dispense with the washer I grind by
ordinary means the rim of the vessel and the underside of the head or cap of the
stopper to form an air-tight joint.
On inserting the plug into the mouth of the Bottle or vessel by passing the vertical
grooves above described over the nibs inside the mouth of the Vessel and slightly
turning the stopper the nibs bearing upon the inclined part of the shank of the
stopper draw the stopper farther into the bottle or vessel thus closing and making
same airtight by the pressure of the cap of the stopper upon the rim of the Bottle
or Vessel.
Fig. 2 shows a modification of this stopper made of metal and applicable to metal
drums, casks, etc. as well as for attaching to Glass or earthenware vessels the sleeve (D)
fits preferably over the neck of the vessel when of Bottle form, or is attached to the
head of the drum. In this sleeve the nibs as above described are cast or fitted
thereto and the mouth is coned to form a seating. The plug is made of any suitable

page_text: materials and formed in the manner above described except that under the head or cap
a cone is formed corresponding to the cone in the sleeve into which it fits when the
plug is inserted and secured as above described.
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
