page_text: LETTERS PATENT to Frederick Foster of 23 Forston Street Hoxton in the
County of Middlesex for an Invention of "IMPROVEMENTS IN SCREW NECK
BOTTLES OR JARS AND IN STOPPERS FOR SAME."
PROVISIONAL SPECIFICATION left by the said Frederick Foster at the
Office of the Commissioners of Patents on the 16th October 1882..
FREDERICK FOSTER of 23 Forston Street Hoxton in the County of Middlesex
"IMPROVEMENTS IN SCREW NECK BOTTLES OR JARS AND IN STOPPERS FOR SAME
"
This invention relates to improvements in the manufacture of bottles or pickle
jars with screw threads within the neck such as are referred to in my specification
N° 466 A.D. 1871. It consists in improving the form of the neck of the bottle.or
jar by making a ledge within the neck (but above the screw thread) in such manner
that the joint may be made here instead of on the top of the neck as heretofore.
By this means a cork washer may be used to make the joint instead of India rubber
when desired, as the cork is confined by the sides of the neck of the bottle and is
not therefore capable of extending laterally and breaking as would be the case if
the joint were made on the top. The stopper I make by preference of earthenware
either bearing a screw thread upon it or being pierced by a hole at an angle with
a slanting recess made at each side of the stopper into which the ends of a wire
passed through the hole may be bent. These bent projecting ends of the wire
prevent the wire from being withdrawn from the stopper and at the same time
they form portions of a screw thread to engage in the screw thread made within
the neck of the bottle.

FREDERICK FOSTER of 23 Forston Street, Hoxton. N. London IMPROVEMENTS
IN SCREW NECK BOTTLES OR JARS, AND IN STOPPERS FOR SAME
This Invention relates to improvements in the manufacture of Bottles or pickle
jars with screw threads within the neck such as are referred to in my specification
N° 466 A.D. 1871. It consists in improving the form of the neck of the bottle or
jar by making a ledge within the neck (but above the screw thread) in such
manner that the joint may be made here instead of on the top of the neck as
heretofore. By this means a cork washer may be used to make the joint instead
of India rubber when desired as the cork is confined by the sides of the neck of
the bottle and is not therefore capable of extending laterally and breaking as would
be the case if the joint were made on the top. The stopper, I minke, by preference
of earthenware.either bearing a screw thread upon it or being pierced by a hole at
an angle with a slanting recess made at each side of the stopper into which the
ends of a wire passed through the hole may be bent. These bent projecting ends
of the wire prevent the wire from being withdrawn from the stopper and at the
same time they form portions of a screw thread to engage in the screw thread made
within the neck of the bottle.
In the accompanying drawings Figure 5 represents an elevation partly in
section of a stopper suitable for a pickle-jar, and Figure 4 a plan of the saine
a. aal showing the mode of fastening in the wires by preference made of vulcanite,
the vertical position of each wire on the plug of the stopper being such that they
all combined match the pitch of the screw-thread formed within the neck of the
bottle. Figure 6 represents a pickle-jar with screw neck suitable for receiving
such stopper Fig 2 represents a stopper suitable for a beer-bottle having an
inclined hole through the plug of the stopper and a curved channel B on each side
into which the ends of the wire (by preference of vulcanite) are bent over forming
a portion of a screw thread of the same pitch as the screw-thread-formed in the
neck of the Bottle. Figure 1 represents a plan of such stopper showing the inclined'
hole E, and the bent over portions of the wire F. Figure 3-represents the neck of
a bottle with screw thread C, and seating D for the washer above the screw
thread.
Having now described the nature of the said invention and the manner in which
the same is to be performed I would have it understood that I claim
1° The hollow stopper for pickle bottles, fitted with wire staples bent over within
the hollow part of the stopper forming together portions of a scrow t thread of the
same pitch as that formed within the bottle neck.
2° The solid plug stopper for smaller neck bottles with angular perforation. and
angular channels in which the ends of the wire are bent over forming portions of
a screw thread and serving to fasten the wire in the stopper
.
3° The form of seating shewn in Fig 3 and Fig 6 for the purpose of using a
washer of cork or other, inodorous material in cases where India rubber may be
objectionable,
All substantially as set forth and described, In witness whereof.I have hereunto
set my hand and seal this sixteenth day of April in the year of our Lord one
thousand, eight hundred and eighty-three
