Year: 1876

page_text: LETTERS PATENT to Samuel Gee, George Gibbs, and Frederick John Garnett,
all of Leeds, in the County of York, for the Invention of " IMPROVEMENTS IN
APPARATUS FOR FORMING INTERNAL SCREW THREADS IN THE NECKS OF
BOTTLES JARS, OR OTHER VESSELS."
Sealed the 29th December 1876, and dated the 26th July 1876.
PROVISIONAL SPECIFICATION left by the said Samuel Gee, George Gibbs,
and Frederick John Garnett at the Office of the Commissioners of Patents on
the 26th July 1876.
SAMUEL GEE, GEORGE GIBBS, and FREDERICK JOHN GARNETT, all of Leeds, in
the County of York. "IMPROVEMENTS IN APPARATUS FOR FORMING INTERNAL
SCREW THREADS IN THE NECKS OF BOTTLES, JARS, OR OTHER VESSELS."
Our improvements refer to tongs for forming within the neck or top of bottles,
jars, and other vessels a screw thread or twist.
The tools or tongs are provided with a screw plug or core which works loosely or
independently of the dies used in the ordinary process of forming the lips or necks
of bottles, jars, or other vessels.
By a convenient catch arrangement applied to the ordinary spring tongs the screw
plug or core may be allowed to revolve either with the tongs or independently, and
that in such a way that when the plug is inserted in the neck and the tongs are
compressed thereon in the workman's hand the plug shall then be free to revolve,
but when the tongs are opened the plug is held fast.
When the bottle neck has thus been formed the plug is screwed out of the neck,
the tongs being theu open or released and the plug fixed in the tongs.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Samuel Gee, George Gibbs, and Frederick John Garnett in the Creat
Seal Patent Office on the 26th January 1877.
SAMUEL GEE, GEORGE GIBBS, and FREDERICK JOHN GARNETT, all of Leccis, in
the County of York. "IMPROVEMENTS IN APPARATUS FOR FORMING INTERNAL
SCREW THREADS IN THE NECKS OF BOTTLES, JARS, OR OTHER VESSELS."
Our improvements refer to tongs for forming within the neck or top of hottles
jars, and other vessels a screw thread or twist.

page_text: The tools or tongs are provided with a screw plug or core which works loosely or
independtly of the dies used in the ordinary process of forming the lips or necks
of bottles, jars, or other vessels.
By a convenient catch arrangement applied to the ordinary spring tongs the
scrow plug or core may be allowed to revolve either with the tongs or independently,.
and that in such a way that when the plug is inserted in the neck and the
tongs are compressed thercon in the workman's hand the plug shall then be free
to revolve, but when the tongs are opened the plug is held fast.
When the bottle neck has thus been formed the plug is screwed out of the neck,
the tongs being then opened or released and the plug fixed in the tongs.
And in order that our Invention may be more completely understood reference is
given to the accompanying Sheet of Drawings and to the letters of reference
marked theroon
Figure 1 is a front elevation; Figure 2, a side elevation; Figure 3, a plan looking
at the bottom of the tool employed for constructing the bottle neck; Figure 4, a
sectional plan of the same through A, B; Figures 5 and 6, 7 and 8, are respectively
modifications of the tool.
a are the legs of the tongs, which are here shewn of ordinary construction, and
b the dies which are for forming the lip of the exterior of the bottle or other vessel.
The tools or tongs are provided with a plug or core c having a portion of its
length screwed, as shewn at d. This core or plug works loosely or independently
of the dies b, but by some convenient catch arrangement so that it can be allowed
when required to revolve with them. Some such catch arrangements are shewn
in the various Figures representing the tongs or tools. A portion of the plug or
corc c passes through the plate e and is made square, as shewn at f; a cross piece
is provided which passes through one side of the tongs at 7, and is fixed to the other
side at i; in the cross piece g is provided a slot hole J, one end of which fits the
square end of the plug or core c, and the other end is so large that the square part
of the plug or core c may turn round in it. When the bottle or other vessel neck
is being formed it is necessary that the screw plug or core should turn round in
the bottle. In order to effect this wo so construct the slot holo J that by closing
the tool on to the bottle or other vessel the square end ƒ of the core or plug c passes
from that part of the slot hole J which fits it into the part in which it can turn
round; by this means the plunger or core c can rotate with the bottle. It is also
necessary, in order to free the screw from the bottle after the neck is completed,
that the plug or core c should be prevented from revolving, for this purpose we so
arrange the slot hole J in the cross piece g that when the tougs are open the square
part of the plug or core C passes into that part of the slot hole J which is made to
fit it, whereby the plug or core c is prevented turning round. It will be understood
in this case that by causing the bottle or other vessel to revolve the screw is
readily extricated. The cross piece K is used as a stay guide or bearing to the plug
or core c.
Figures 5 and 6 illustrate other catch arrangements.
Instead of having the square f on the end of the plug or core c, as described in
the former arrangement, we provide clutch teeth on the end of the plug or core c,
as shewn at l, and for the purpose of fixing the same imposition when the bottle
or other vessel neck is being formed we provide the toothed block m, which when
thrown into gear with the plug or core c prevents it from turning round, and when
thrown out of gear allows the plug to revolve with the bottle or other vessel; this
operation is effected in the same manner as in the herein-before described arrange-
ment, the required motion being transmitted through the rods or links n.
centre piece o is used as a carrier for the block, and also for the plug end.
The
Figure 7 is precisely the same as that represented at Figures 5. and 6, except that
instead of the teeth we make the end of the plug or core c square, and provide

page_text: a block
P' in which is a square hole 7 which by passing on to the square prevents
the plug or core c from turning round.
In some cases a vertical channel is required to he formed through the threads
in the bottle or other vessel, for this purpose we provide special dies which pass into
the bottle or other vessel neck as the tongs are closed, this arrangement gives the
required formation. These dies are, as shewn at Figure 8, attached to a sliding
pieces through which the required motion is imparted by means of the rods t. The
arrangement for preventing the plug or core c from turning round is precisely the
same as that shewn at Figures 1 and 2.
Having now described the nature of our said Invention and shewn by Drawings
how the same may be carried into practice, we would have it understood that we
do not limit ourselves to the exact details or configuration of the various parts we
have explained and shewn, as the same may of course be varied or modified without
in any way departing from the nature of our said Invention, but what we do claim
and desire to be secured to us by Letters Patent is,―
Firstly. Fitting tongs substantially of the ordinary construction for forming the
outside of bottle necks with a central plug for forming screw thread in the bottle
neck, the said plug being by suitable catch appliance so arranged that it may as
required be held fast with the tongs proper, or be free of them as set forth.
Secondly. The construction of the appliances for forming screw thread with or
without channel in bottle necks as herein more particularly described and illustrated
in the accompanying Drawings.
In witness whereof, we, the said Samuel Gee, George Gibbs and Frederick
John Garnett, have hereunto set our hands and seals, this Twenty-fifth day
of January, in the year of our Lord One thousand eight hundred and
seventy-seven
