I HIRAM CODD of No 41 Gracechurch Street in the City of London Bottle
Manufacturer do hereby declare the nature of my invention for "IMPROVEMENTS IN
THE 'MANUFACTURE OF BOTTLES AND IN TOOLS TO BE EMPLOYED IN FORMING THE
SAME" to be as follows:-
In forming the necks of bottles tools known as tongs are employed which being
made to close on the neck and at the same time rotated reduce the neck to the
desired form.
For the purpose of forming bottles with a screw thread on the exterior of the
neck I employ tongs having a moveable piece in the jaw capable of sliding in
the jaw in a direction parallel to the axis of the bottle. This moveable piece in the
part which comes into contact with the glass has inclined grooves in it corresponding
to the threads of .the screw it is desired to produce.
As the jaw is closed against the glass with a rotary motion the moveable picce
travels endwise and produces a continuous screw thread around the neck.

I HIRAM CODD of 41 Gracechurch Street in the City of London Bottle
Manufacturer, do hereby declare the nature of my invention for "IMPROVEMENTS IN
THE MANUFACTURE OF BOTTLES AND IN TOOLS TO BE EMPLOYED IN FORMING THE
-SAME" and in what manner the same is to be performed to be particularly
-described-and-ascertained in and by the following statement:-
In forming the necks of bottles tools known as tongs are employed which being
made to close on the neck and at the same time rotated reduce the neck to the
desired form.
For the purpose of forming bottles with a screw thread on the exterior of the
neck I employ tongs having a moveable piece in the-jaw-capable of sliding-in
the jaw in a direction parallel to the axis of the bottle. This moveablo piece in the
part which comes into contact with the glass has inclined grooves in it corresponding
to the threads of the screw-it-is-desired-to-produce..
As the jaw is closed against the glass with a rotary motion the moveable piece
travels endwiso and produces a continuous screw thread around the neck.
The drawing hereunto annexed shows a side elovation of tongs constructed in
the manner I prefer for carrying out my Invention.
In this tool one only of the jaws is fitted with a sliding piece as above described-
the opposite jaw is composed of a cylinder capable of revolving around a pin on the
extremity of the arm which carries it as described in the specification of my
application for a Patent No 10,419 in the year 1884. The cylinder is of a diameter
equal to the exterior diameter of the head of the bottle to be moulded as described
in the specification above mentioned and has a screw thread cut around it corro-
sponding to the screw thread to be cut around the head of the bottle. When the
tongs are closed upon a partially formed head of a bottle the cylinder above
mentioned will be rotated and aid in moulding a screw thread around the head-it
also serves to assist in moving the slide backwards and forwards as the bottle is
retated.
A is the sliding piece having inclined grooves in its face corresponding with the
screw thread to be formed around the head of the bottle-B is the cylinder mounted
upon a pin at the extremity of the other arm of the tongs. C is a pin projecting
from the slide A and entering a slot in one end of a lever D-The lever turns upon
a fulcrum carried by one side of the disc swiller plate E and at its opposite end it
carries a disc or plate which has a long tooth projecting from it which engages with
the screw thread cut around the cylinder so that whenever the cylinder is rotated
by the friction against it of the head of the bottle the lever is turned on its fulcrum
and the slide moved endwise to or fro according to the direction in which the
bottle is being turned. In this way the cylinder and slide are always kept in
proper relative positions to mutually assist one another in forming the screw
thread.
It is not essential to use a rotating cylinder on one side of the tongs as above
described to move the slide on the opposite side to and fro-a slide might be fitted

page_text: in each jaw of the tongs and each have inclined grooves on its face to form the
screw thread, but in this case the slides would have always to be both brought back
against stops before grasping the head of a bottle between them so that the
screw thread formed by one slide may coincide with the screw thread formed by
the other slide.
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
1. The construction and use of tongs employed in the manufacture of bottles
with a slide in one or both of their jaws capable of sliding endwise in a direction
parallel to the axis of the bottle and having inclined grooves cut in their face
substantially as described.
2. The construction and use of tongs employed in the manufacture of bottles
.substantially as herein before described and illustrated in the drawing annexed.
