like Hollow Vessels.
I, THOMAS TAYLOR of the firm of Taylor, Tunnicliffe and Company of Hanley in
the County of Stafford, Manufacturing Potter, do hereby declare the nature of this
invention to be as follows:-
My invention relates to the screw stoppers of bottles, jars and other internally
screwed necks, or orifices, and which said invention is an improvement on Letters
Patent granted to Sarah Ann Bull dated the 24th day of February 1883 and
numbered 1021.
In screwed stoppers made according to the said patented invention, the shank or
stem of the stopper, next to the head part, or that part between the underside of the
head, to near the end of the shank, is of reduced diameter and unwormed; that is, its
surface is perfectly plain; and upon this plain part of less diameter, a short cork
cylinder, and also a loose flanged top is placed; and which said short cylinder, is of a
diameter about equal to the wormed end of the shank.
Screwed stoppers so constructed, are rendered inefficient, after having for a time
been used, by the cork jacket, or outer covering, becoming cut, distorted or burst, by
the threads of the internally screwed necks of the vessels with which the said stoppers
are used, pressing more upon one portion of the cork surface, than on the other.
The object of my invention is to remedy this defect by worming the whole of the
stem, or nearly the whole of the stem from top to bottom, and making that part, from
near the end of the stem, to the underside of the head, (with the exception of a small
collar) of less diameter, than the other part, but with a thread of the same pitch; and
upon the said reduced part of the shank as aforesaid, a flanged short cylinder or ring
of cork, india-rubber or other like yielding material is placed. This short cylinder is
of the same, or of about the same diameter as the enlarged screw part as aforesaid.
Thus the stopper consists of a screwed shank of two diameters, with a coating or
covering of cork, india-rubber or the like upon the lesser of them; so that when in

page_text: use, the extreme wormed end of the shank (which may be only a part of the thread)
fits into the she wormed interior part of the neck of a vessel, and forms the lead in
screwing; while the yielding outer covering of cork or rubber, on the part of lesser
diameter, takes into, and follows the contour of the threads of the said parts, upon
which it surrounds, on the screwing up of the said stopper, within the neck of a bottle
or other vessel; so that the standing out portions of the threads of the one, press the
cork or the like, into the depressed or sunken portions of the threads of the other,
thereby preventing cutting, bursting or the like, to the said cork or outer covering.
Dated this Twenty-first day of May 1887.

like Hollow Vessels.
I, THOMAS TAYLOR of the firm of Taylor, Tunnicliffe and Company of Hanley in
the County of Stafford, Manufacturing Potter, 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 :-
My invention relates to the screw stoppers of bottles, jars, and other internally
screwed necks or orifices, and which said invention is an improvement on Letters
Patent granted to Sarah Ann Bull dated the 24th day of February 1883 and
numbered 1021.
In screwed stoppers made according to the said patented invention, the shank or
stem of the stopper, next to the head part, or that part between the underside of the
head, to near the end of the shank, is of reduced diameter and unwormed; that is, its
surface is perfectly plain; and upon this plain part of less diameter, a shirt cork
cylinder, and also a loose flanged top is placed; and which said short cylinder, is of a
diameter, about equal to the wormed end of the shank.
Screwed stoppers so constructed, are rendered inefficient, after having for a time
been used, by the cork jacket or outer covering, becoming cut, distorted or burst, by
the threads of the internally screwed necks of the vessels with which the said stoppers
are used, pressing more upon one portion of the cork surface, than on the other.
The object of my invention is to remedy this defect, by worming the whole of the
stem, or nearly the whole of the stem, from top to bottom, and making that part, from
the end of the stem, to the underside of the head, of less diameter, than the other part,
but with a thread of the same pitch; and upon the said reduced part of the shank as
aforesaid, a flanged short cylinder or ring of cork, india-rubber or other like yielding
material is placed. This short cylinder is of the same, or of about the same diameter
as the enlarged screw part as aforesaid.
Thus, the stopper consists of a screwed shank of two diameters, with a coating or
covering of cork, india-rubber or the like upon the lesser of them; so that when in
use, the extreme wormed end of the shank (which may be only a part of the thread)
fits into the she wormed interior part of the neck of a vessel, and forms the lead in
screwing; while the yielding outer covering of cork or rubber, on the part of lesser
diameter, takes into, and follows the contour of the threads of the said parts, upon
which it surrounds, on the screwing up of the said stopper, within the neck of a bottle
or other vessel; so that the standing out portions of the threads of the one, press the
cork or the like, into the depressed or sunken portions of the threads of the other,
thereby preventing cutting, bursting or the like, to the said cork or other outer
covering.
Figure 1 represents in front elevation, a screw stopper made according to this
invention. Figure 2 represents the same partly in elevation and partly in vertical
section. This said view represents the shank of the stopper which is of two diameters,

page_text: in elevation, while the cork jacket, or yielding outer covering, which embraces the
part of lesser diameter, is shown in section. Figure 3 represents the stopper, with a
necked shank, or with the outer yielding covering removed. Figure 4 is a plan of the
underside of figure 1, and figure 5 is a vertical section of figure 3. Figure 6 is a
section of the washer, and yielding cork jacket, which latter consists of a short
cylinder of cork. Figure 7 shows the stopper when in use, in the neck of a bottle.
Figure 8 shows a stopper in which the screw threads, and spaces between the threads,
are semi-circular.
a is the head, and b, c, is a screwed shank of two diameters; the part 6 which is
disposed between the end c, and the underside of the stopper head is of less diameter,
than the other screwed part or end c.
This end is left naked, and is of the proper
diameter, for the taking into, of a corresponding she thread, in the neck of a bottle.
d is a short cylinder of cork, extending from the top edge of the larger screwed
part,.which is the lead to the stopper, to the underside of the head; and when the
stopper is in use, the said yielding jacket or outer covering, takes the same screw
thread and diameter, as that of.the said lower part or lead.
e is a washer disposed between the top of the cork jacket on the underside of the
head, and serves to ensure a more perfect joint.
The outer covering d may be of india-rubber, cork, soft wood, or other similar
yielding material.
I wish it to be particularly understood that my invention consists not in a stopper
whose shank is of two diameters, a plain part, and a screwed part, and with the part
of least diameter encircled by a plain short cylinder of cork, or a stopper with an
entirely screwed shank, uniform in diameter, but a stopper, whose shank is entirely
screwed, but of two diameters, and around the screwed part of least diameter, a short
cork cylinder or other yielding covering, encircles, leaving the screwed end which is
of larger diameter, naked.
By making stoppers as described, no cracking or bursting of the cork, or other
yielding covering takes place when in use, as is common with other stoppers of a
like kind.
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.―
First. The improvement in screw stoppers, having stems of two diameters, as
herein-described and illustrated; that is, worming or screwing both diameters, or both
the throttled and the enlarged parts of the said stems, substantially as and for the
purpose herein described and set forth.
Secondly. Encircling the screwed throttled part of the stems of screw stoppers,
with a covering or jacket of cork, india-rubber or other like yielding material,
substantially as described and set forth.
