A Tool for Moulding Bottle Necks.
We, WILLIAM HENRY WATTS of 54 Marshall Street, Golden Square,
London Gunsmith HORACE YNYR EVEREST 381 Goldhawk Road Hammersmith
London Clerk and JOHN CREASY of 9 Mermaid Court Borough Southwark,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
"
Our invention consists of a pair of " tongs or glass bottle makers tools for
finishing off bottle necks. We provide the tongs with a bow spring, the stalk of
the tool is hollow and attached to the end of the stalk we provide a hollow box.
This hollow box has a female screw cut in it, and a screw nut to fit into the same.
We also provide and place in the box a plug, which enters the bottle neck, this
plug, with the levers (hereafter described) attached, revolves with the bottle in
the process of finishing. To agitate or expand the levers, which move through
the plug, we provide a cross bar to the tongs, and while the workman is closing the
tongs, he moves a piston:-rod (automatically) that is inserted in the barrel of the
stalk. The end of the piston-rod (being tapered) will thereby force the levers
outward from the plug, thus projecting them into the glass, and so make the
required indentations in the neck while the bottle and plug are revolving in the
making of the bottle. These indentations are rectangular, or of any configuration
to match a stopper having suitable projections to fit under the shoulders of the
indentations.
By the automatic expansion of the spring tongs (after the making of the
indentations) the levers are made to retire back into the plug, so as to free
the bottle from the tool.
By means of this tool we effect our object of forming in the process of bottle
making, grooves rims or indentations of any configuration, internal or external,
in place of a screw neck, and designed to securely lock a bottle stopper,
hermetically sealing the contents of the bottle, and so, forming by one half turn
of the stopper, an easier and readier mode of attachment and detachment to
and from the bottle.

page_text: 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 invention relates to a tool for moulding bottle necks with internal recesses
and it is primarily designed to produce a bottle neck of the character referred to
in the Specification of Letters Patent granted to William Henry Watts and
Horace Everest dated the 29th day of March 1895 No. 6478, and the present
invention consists of a specially constructed too! for finishing the bottle necks.
In carrying the invention into effect the tool is formed like a pair of tongs
united by a bow spring which exercises a tendency to force the tongs apart.
The tool is furnished with a "stalk" which is at its lower end fixed with the
bow part thereof and this "stalk' is formed hollow for the purpose hereinafter
described.
"
Upon the upper end of the "stalk" is provided a box or hollow boss which is
formed with a female screw to receive a correspondingly threaded plug or nut
which carries with capability of revolving a plug or nozzle adapted to enter the
bottle neck and revolve therewith in the process of finishing.
The plug or nozzle which passes through the nut is formed hollow and interiorly
furnished with two levers mounted upon axes of motion and these levers at their
upper ends are shaped to form the required recesses in the bottle-neck and the
nozzle or plug is formed with corresponding slots or openings so that the levers
may be projected beyond the surface thereof at the times desired.
In order to give this motion to the levers the upper and lower ends thereof are
formed with internal projections and a vertically moveable rod is mounted in the
hollow "stalk" and is formed with an inclined or rounded enlargement or head
which in the upward movement of the rod acts upon the upper ends of the levers
to project them from the nozzle or plug whilst it is furnished with a second
enlargement which in the downward movement thereof retracts the levers within
the area of the nozzle.
The required vertical movements are given to the vertical rod by means of a
cross-bar which is centrally connected with the vertical rod by means of a pin
passing through slots in the "stalk" and the outer ends of the cross-bar are formed
with cam slots which engage studs upon the tongs so that as the workman closes
the tongs to form the bottle neck, the vertical rod will be raised and will thereby
force the levers outward and project them through the slots in the nozzle or plug
and into the glass and thus make the required indentations in the bottle neck
whilst the bottle and nozzle or plug are together revolving during the making of
the bottle.
Upon the workman after the formation of the indentations relaxing his grip
upon the tongs the latter will by reason, of the bow-spring automatically open or
expand and by this reverse movement the cross-bar will be depressed carrying
with it the vertical rod and thereby retracting the levers within the nozzle or plug
so as to free the finished bottle from the tool.
The indentations may be of rectangular or other suitable shape according to
the particular construction of stopper to be employed in connection with the
bottle.
And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully
to describe the same.

In the several figures in which like parts are indicated by similar letters of
reference Figures 5 to .22 are drawn to an increased scale with respect to
Figures 1 to 4.
a represents the legs of the tool which are formed like those of a pair of tongs
united by a bow spring a¹ which exercises a constant tendency to force the same
apart and at their upper ends they are provided with jaws a adapted to shape the
exterior of the bottle neck and 6 represents the "stalk" which at its lower end is
adjustably fixed with the bow part al of the tool by means of a screw thread b¹
and binding nuts 62 and this "stalk" b is formed hollow for the purpose hereinafter
described.
Upon the upper end of the "stalk" b is provided a box or hollow boss 6* which is
formed with a female screw to receive a correspondingly threaded plug or nut c
furnished with studs c¹ to facilitate the turning thereof and this plug or nut c
carries with capability of revolving a plug or uozzle c adapted to enter the bottle
neck as shown in Figures 5 and 7 and revolve therewith in the process of
finishing the same.
The plug or nozzle which passes through the nut c and is inserted from below
is at its lower end formed with a flange which through an intervening washer c*
takes a bearing against the underside of the nut o whilst it is held in place by means
of a collar c which bears upon the top surface of the nut c and is interiorly formed
with grooves or slots c to permit of its passing over the heads c of the levers c
hereinafter described after which: it is turned a partial revolution and is then held in
place by such heads c³ but with capability of freely revolving.
is
The nozzle is formed hollow and interiorly furnished with two levers c
mounted upon axes of motion c8 and these levers at their upper ends c are shaped
to form the required recesses f' in the bottle neck fand the nozzle or plug
formed with corresponding slots or openings c* so that the heads may be
projected beyond the surface thereof at the times desired.
To facilitate the construction of the nozzle and the placing in position of the
levers c¹ the nozzle c³ is formed in two parts pin jointed together at the upper ends
thereof and these two parts are held together by a screw c** aided by the nut c and
collar c.
In order to project the heads c of the levers 7 through the slots c* of the
nozzle at the times desired the heads c' of the levers are bevelled or inclined

page_text: upon their inner faces at co and at their lower ends they are formed with bevelled
projections c whilst a vertically moveable rod dis mounted in the hollow "stalk "b
and is formed with an inclined or rounded enlargement or head d which in the
upward movement of the rod acts upon the inclines co upon the upper ends of
the levers c' to project the parts c through the slots c* of the nozzle whilst the
rod d is furnished with a second enlargement & which in the downward movement
thereof acts upon the parts c¹¹ to retract the heads c' of the levers within the area
of the nozzle c³ or approximately so.
The required vertical movements are given to the rod d by means of a cross
bar e which is centrally connected with the vertical rod d by a pin el passing
through the slots in the "stalk" b and through a sleeve e sliding on the
"stalk" 6 to which latter the cross bar e is fixed by screws and the outer ends of
the cross-bar e are formed with cam slots e³ ³ which engage studs a³ upon the
tongs a so that as the workman closes the tongs to form the bottle neck the rod d
will by the parts e³ of the cam slots be raised and will thereby force the heads c
of the levers outward and project them through the slots of the nozzle or
plug and into the glass and thus make the required indentations f₁ in the bottle
neck, whilst the parts or dwells * of the cam slots in the further compression
of the tongs a will permit the jaws a' to close upon and shape the bottle neck f
without imparting any further movement to the rod d and the levers 7 and these
operations take pluce whilst the bottle and nozzle or plug c are together revolving
f
during the making of the bottle f.
Stops a carried by the legs a are employed to come against the box 63 in the
closed position of the tool and thereby limit the extent to which the jaws a
compress the bottle neck whilst the concave formation of the stops a* in conjunction
with the circular shape of the box 6 acts to truly guide the jaws a² into correct
position.
Upon the workman after the formation of the indentations f' relaxing his grip
upon the tongs a the latter will by reason of the bow spring al automatically open
or expand, and by this reverse movement the cross-bar e will be depressed carrying
with it the vertical rod'd and thereby retracting the heads c of the levers c' within
the nozzle or plug so as to free the finished bottle from the tool.
The heads of the levers c may be shaped to form the indentations f¹ of
rectangular or other suitable configuration according to the particular construction
of stopper to be employed in connection with the bottle.
It will be obvious that the details of construction of the tool may be more or less
varied without departing from the principle thereof.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A tool for moulding bottle necks furnished with jaws adapted to form the
exterior of the bottle neck and with a rotative nozzle or plug designed to shape the
