PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Making and
Finishing Externally Threaded Bottles, Jars, or Vessels.
We, CAIN DOUGLAS, Bottle Maker and BEN LISTER, Fitter, both of Cromwell
Road, Thornhill Lees, Dewsbury in the County of York, do hereby declare the
nature of this invention to be as follows:-
:-
The object of our invention is to make and finish bottles, jars and vessels with
finished external threads around their necks and rims.
I employ the ordinary tool used in the glass bottle trade, which is in the form of
a spring tongue, with a central divided spring plug, upon the central bar or swiller
I fix a recessed plate within which is a slot for the spring plug to pass through and
to allow of their opening, within the recess of the plate is a disc having at one
end a flange fitting into the recess in the plate and held therein by a cap and
screws, the edge of the flange of the plate is notched at intervals for the reception
of a catch carried upon a slotted cross bracket or arm, upon the tongue arms, when
the arms are extended the catch projects and enters one of the notches in the flange
of the disc and holds it, when the arms are compressed it withdraws the catch and
leaves the disc free to revolve, within the disc is formed an internal thread the
size and shape required to be formed upon the neck of the bottle, jar or vessel.
The action is as follows:
The bottle neck is placed in the tool and spun in the usual way, as the arms are
compressed the split spring plug, opening, presses the glass or metal into the
threads of the disc, the disc is free and revolves with the spinning of the bottle,
so forming a corresponding thread upon the outside of the neck to that within
the disc.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Making and
Finishing Externally Threaded Bottles, Jars, or Vessels.
We, CAIN DOUGLAS, Bottle Maker and BEN LISTER, Fitter, both of Cromwell
Road, Thornhill Lees, Dewsbury in the County of York, 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 our invention is to make and finish bottles, jars, and vessels with
finished external threads around their necks and rims.

page_text: We employ the ordinary tool used in the glass bottle trade, which is in the form
of a spring tongue A, with a central divided spring plug B.
Upon the central bar or swiller C, we fix a recessed plate D, within which is a
slot E, for the spring plug B to pass through, and to allow of their opening;
within the recess H of the plate D, is a disc F, having at one end a flange G,
fitting into the said recess H in the plate D, and held therein by an annular
cap J, and screws K, the edge of the flange of the disc F is notched at intervals,
see Fig. 4, for the reception of a catch L, carried upon a slotted cross bracket
or arm M, upon the tongue arms N; when the arms are extended see Fig. 1, the
catch L projects and enters one of the notches in the flange G, of the disc F,
and holds it; so that when the thread has been formed upon the external periphery
of the bottle neck, the loose disc is held fast until the bottle is removed, and a
second bottle placed in the tool; when the arms are compressed see Fig. 2. the
catch is withdrawn, by means of pins or studs R, upon the tongue arms, working
within slots S in the cross bracket M, leaving the disc free to revolve.
Within the disc is formed an internal thread P, the size and shape required to
be formed upon the neck of the bottle, jar or vessel.
The action is as follows:-
The bottle neck is placed in the tool and spun in the usual way, as the arms N
aro compressed, the studs T bear against and open the split spring plug B,
which presses the glass or metal into the threads P of the disc F, and the
catch L, having been simultaneously withdrawn, allows the disc to revolve with
the spinning of the bottle, so forming a corresponding thread upon the outside of
the neck to that within the disc.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
--
1. For forming external threads upon bottles, jars, or other vessels, the use
and employment of loose disc F, with notched flange G, catch L, and spring plug B,
operated in the manner, substantially as shown and described.
2. The use and employment upon the arms of the tongue A, of cross bracket M,
with slots S, and pin or catch L, for engaging with and holding disc F fast, whilst
the bottles are removed and replaced as shown and described.
Dated this Third day of November 1893.
