ROBERT JOHN SMITH, of the City of Manchostor. "IMPROVEMENTS IN CLOSING
OR STOPPERING GLASS AND OTHER BOTTLES, AND IN TOOLS FOR MAKING THE
SAME."
These improvements consists in forming a double female screw thread on the
inside of the neck of glass and other bottles for containing malt and other liquids
to receive a corresponding male thread formed upon a metal or other stopper which
is provided with a flange and cork or other suitable washer, so that when screwed
home into the neck of the bottle such bottle is effectually closed.
In performing my Invention I arrange a double male screw thread upon the
plug of the tool used by glass bottle makers for putting the ring round the neck,
and which plug is in accordance with this Invention capable of revolving whilst
the bottle is rolled to and fro in the ordinary manner, so that in the act of putting
on the ring the female screw thread is also formed inside the neck, such plug being
held stationary by a suitable flat when removing or unscrewing the bottle.

ROBERT JOHN SMITH, of the City of Manchester. IMPROVEMENTS IN CLOSING
OR STOPPERING GLASS AND OTHER BOTTLES, AND IN TOOLS FOR MAKING THE
SAME."
Fig. 1 represents so much of the neck of an ordinary glass malt liquor bottle as
is necessary to illustrate the application of my improvement; and Fig. 2 shews the
improvement applied to an infant's feeding bottle.
The improvements consist in forming a double female screw thread A. on the
inside of the neck of glass and earthenware bottles for containing malt, aerated,
and other liquids, to receive a corresponding male thread formed upon a stopper B,
which is made of metal, glass, or other suitable material. This stopper B is pro-
vided with a flange C and cock, or other suitable washer D, so that when screwed
home on to the neck of the bottle such bottle becomes effectually closed or
stoppered.
It will be apparent that this method of closing or stoppering bottles dispenses
with the necessity of using a corkscrew, as the stopper can be unscrewed by
hand.
Having thus particularly described my said Invention, and the best methods with
which I am acquainted for carrying the same into practical effect, I wish it to be
distinctly understood that I am well aware that some description of bottles have
hitherto been made with a single screw thread formed inside their necks, but by
adopting a coarse double screw thread, as herein-before described, and illustrated on
the accompanying Drawing, and which I clain as my Invention, a bottle can be a
opened in considerably less time than has hitherto been practicable.
In witness whereof, I, the said Robert John Smith, have hereunto set my
hand and seal, this 6th day of November, in the year of our Lord Ono
thousand eight hundred and seventy-eight.
