We DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer, and BENJAMIN STONER of Bridge Street of the
same place Mechanic do hereby declare the nature of our invention for IMPROVEMENTS
IN TOOLS FOR FORMING BOTTLE MOUTHS to be as follows :—
The object of this Invention is to construct the plug which forms the interior of
Bottle Mouth, so that a screw portion thereof revolves with the mouth of bottle during
the time a groove is being formed therein, and locks immediately the cutters leave
the groove so that the formed mouth of Bottle may be unscrewed from the plug.
To attain the above described object une Tools are constructed in the following
manner: Where our invention is applied to Tools whose cutters rotate to position for
forming square bevel or other grooves as per our patent specifications Number 8299
of 1885 and Number 13669 of 1886 it consists in placing on the portion of plug which
comes between the face of the swiller and the cutters a ferrule whose exterior periphery
has a screw thread or threads made in form to suit the desired shape of the interior
5 of bottle mouth above the groove. When the spring handles are compressed and the
rotating parts of the plug are accordingly apart, the screwed ferrule is free to revolve
with the mouth of the Bottle during the formation thereof; But when the handles are
released the ferrule becomes locked, by means of the rotating parts of the plug closing
and their back portions coming in contact with suitable notches formed on the interior
periphery of the ferrule and at the end thereof next to the cutters made with or attached
to the rotating parts of the plug. Where our invention is applied to tools having
spring dogs and whose cutters are pressed out into position for forming the groove
in the mouth of Bottle, it consists in placing the herein before described ferrule onto
the part of plug which comes between the face of the swiller and the cutters formed
5 on the spring dogs; the said ferrule can freely revolve on this part of plug when the
spring handles are compressed, but is prevented moving longitudinally by means of a
raised ring formed on said ferrule, which raised ring has a bearing in a recess formed
by means of attaching suitable plates to the face of the swiller, or the ferrule may be

page_text: prevented moving longitudinally by any other suitable means; When the spring
handles are compressed and the spring dogs forced apart by means of the presser, the
screwed ferrule revolves with the Bottle mouth during the formation thereof; but
when the handles are released the said ferrule becomes locked by means of the
following arrangement; a guide similar to the one which works the presser, but
working conversely 'thereto has secured to it a spindle which passes through the
swiller, and when the spring handles are released after the Bottle mouth has been
formed the end of said spindle is forced by the guide into a hole indent or notch
formed in the end of the ferrule which works against the face of the swiller, and thereby
locks the ferrule, any suitable number of holes indents or notches may be formed in
the end of the ferrule for the reception of the end of the spindle.
The above described part of our invention may be applied to any kind of Tool for
forming grooves in bottle mouths.

We DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the County of
York Glass Bottle Manufacturer, and BENJAMIN STONER of Bridge Street of the
same place, mechanic 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 :-
The object of this invention is to construct the plug which forms the interior of the
bottle mouth so that a screw portion thereof revolves with the mouth of bottle during
the time a groove is being formed therein, and locks immediately the cutters leave
the groove so that the formed mouth of bottle may be unscrewed from the plug ; to
attain which the Tools are constructed with the improvements illustrated in the
drawings annexed, of which the following is a description:
:-
Fig. 1 is a front view of the swiller and part of plug with the rotating parts thereof
removed; and Fig. 2 is a longitudinal sectional elevation taken on line a a of Fig. 1
and shows the dogs and cutters rotated to position for forming bottle mouth. Fig. 3
is an elevation of our improvements applied to Tools with spring dogs, and Fig. 4 is
a back end view of the screw ferrule.
Referring to Figs. 1 and 2 the ferrule works on the part of plug p' and comes between
the cutters c'e' (which are either formed on or attached to the parts cc) and the face
of the swiller a. The said cutters ce may be made either to form a square groove in
bottle mouth in manner described in our specification No. 8299 of 1885, or an under-
cut or bevel groove in manner described in our specification No. 13669 of 1886. The
ferrule has a suitable scrow thread or threads formed on its exterior periphery.
When the spring handles of the Tools are compressed and the rotating parts cc of
the plug are consequently apart (as shown at Fig. 2) the screw ferrule ƒ is free to
revolve with the mouth of bottle during the formation thereof, but when the said
spring handles are released the ferrule becomes locked by means of the rotating
parts of the plug c closing and their back portions c³ ³ coming in contact with the.
notches which are formed on the interior periphery of the ferrule and at the end
thereof next to the cutters c¹ c¹.
Referring to Figs. 3 and 4 our invention is there shown applied to Tools having
spring dogs cc whose cutters c' e' are pressed out into position for forming the
groove in the mouth m of Bottle B as shown at Fig. 3. In Fig. 3 our hereinbefore
described ferrule fis placed between the face of swiller and the cutters c¹ c' formed
on the dogs c. The said ferrule can freely revolve on the top part of plug pl shown
at Fig. 4 when the spring handles are compressed as shown at Fig. 3; but the
said ferrule is prevented moving longitudinally by means of a raised ring which
has a bearing in a recess formed by means of attaching suitable plates to the face
of the swiller s. When the bandles h h are compressed and the spring dogs cc forced
apart by means of the presser t, the screwed ferrule revolves with the bottle B during
the formation of the mouth m thereof, but when the handesh are released the said

page_text: ferrule becomes locked by means of the following arrangement: A guide k (similar
to the guide which works the presser t, but working conversely thereto) has secured
to it a spindle o; when the handles are released as beforesaid after the bottle mouth
has been formed, the end of the spindle o is forced by means of the guide k into a
hole, indent or notch f' formed in the end of the ferrule f which works against the
face of the swillers and thereby locks the ferrule f.
Any suitable number of holes, indents or notches f² may be formed in the ferrule f.
The improvements illustrated and described at Figs. 3 and 4 may be applied to any
kind of Tool for forming grooves in bottle mouths.
Having now particularly described and ascertained the nature of our said invention'
and in what manner the same is to be performed, we declare that what we claim is :-
==
1. In connection with Tools for forming grooves in bottle mouths, the adaptation
of a screw ferrule which can freely revolve during the formation of bottle mouth,
and is securely locked previous to the bottle mouth being withdrawn or screwed from
the plug substantially as described and illustrated at Figs. 1, 2, 3, and 4, of the.
accompanying drawings or any mere modification thereof.
