We, RICHARD WILLIAMS THOMAS of 121 Cheapside in the City of London Artist
and THOMAS' PATENT BOTTLE AND STOPPER COMPANY LIMITED of 10 & 11 Cursitor
Street Chancery Lane in the County of Middlesex Bottle Stopper and Tap
Manufacturers do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of an improved apparatus for forming
grooved or partially grooved necks or recesses inside bottles, jars and the like of
glass or other material capable of similar treatment, where screwed, ball or other
special stoppers are employed.
According to this invention we mount the stem or rod carrying the mandrel on
a pivot or centre on the end of the springs carrying the clamping jaws or otherwise
so that the jaws may be brought together by the grasp of the hand.
Between and near the crank portion or the upper end of the springs carrying the
clamping jaws we place a bolt free to slide and adjusted by nuts against the sides
of the springs, it carrying a guide through which the pivotted stem or rod passes.
Above this bolt we arrange a pair of bolts oppositely facing and working in tubes or
sleeves attached to each side of the springs, and capable of lateral adjustment by screws
and nuts or otherwise. These screws carry segmental plates or collars carrying lugs
through which passes a guiding rod fixed to one lug and sliding in the other and
which can be brought to and fro by the movement of the springs carrying the
clamping jaws.
The aforesaid stem or rod carries a plate to which are pivotted a pair of levers one
end of which controls the cutting dies or edges which are made to protrude from the
mandrel when operated, and the other end advantageously carrying anti-frictional
rollers or bearings working against the segmental plates or collars aforesaid.
Suitable springs tend to press the levers outwardly so as to bear towards or against
the segmental plates or collars when the spring jaws clamp the bottle or like
receptacle neck.
In using the apparatus the workman places (say) the heated bottle neck on the
mandrel and clamps the springs together so approaching the clamping jaws. The
segmental plates or collars approach each other to guide the anti-frictional Follers or
bearings carried by the rod or stem, and the workman so now holding the bottle or
the like can roll the same over a table or like surface provided for the purpose, the
mandrel rotating with the bottle or the like, while the dies or cutting edges are
protruding from the mandrel.
By this means the inner portions of the necks of bottles or the like can be formed
in any desired shape and the risk of breakage in forming such necks for bottles or
like receptacles is decreased.

Pin1

page_text: 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:
screw
This invention has for its object the construction of an improved apparatus for
forming grooved or partially grooved necks or recesses inside bottles jars or like
receptacles formed of glass or other material capable of being operated upon by such
apparatus, such grooved or recessed necks being applicable where "
""ball" or
other analogous stoppers are used to close such bottles jars or like receptacles.
Reference may now be had to the accompanying sheet of drawings which shew the
application of the apparatus for making a "bayonet-joint" stopper though such
apparatus may have its details modified to operate on necks or recesses of different
pattern.
"
In Figure 1 A represents a bottle neck made for a bayonet-joint" stopper B. B¹
are the vertical grooves and C. C' the horizontal grooves as will be well understood.
This figure is shewn in vertical section simply as an index to the hereinafter
described tool and its operation.
Figure 2 is a front elevation of the tool or apparatus, with the clamping jaws
open.
Figure 3 is a similar view but with the jaws set for clamping a bottle neck between
them.
Figure 4 is a sectional side elevation of the last. recited figure shewing the
protruding dies in the act of cutting into the softened glass or other material to be
operated upon.
Figure 5 is a plan view of the tool or apparatus, shewing the clamping jaws
distended.
According to this invention we mount the stem or rod A carrying the mandrel B
on a pivot or centre from or on the clamping jaws C. C¹ or otherwise so that the
jaws may be brought together by the grasp of the hand or hands.
These jaws C. Care carried on cranked stems D. D¹ as shewn, or may be made
integral therewith.
In the method delineated such as clamping the jaws C. C₁ to the stems D. D'
differently formed jaws may be adjusted and used on the same tool by slackening
the nuts a. a on the screwed ends b. 6' of the stems D. D¹ screwing them off and
slipping the lugs c. c¹ of the jaws off the stems D. D' and replacing them with fresh
ones and adjusting the same.
Between and near the cranked portion of the stems D. D' (or which really act as
springs as they are united by their lower ends being thinned out and tempered to
form a uniting spring E.) we place a bolt or stem A secured to the uniting spring E
by nut or otherwise.
This bolt or stem passes through a boss G carried by a yoke H. This yoke has a
pair of converging slots e. e¹ formed therein and which slots ride on studs f,f¹,
fixed to each stem D. D¹ carrying the clamping jaws C. C. The yoke H also carries
a tongue or bolt I free to advance and retreat with the yoke. The bolt or stem A
secured to the uniting spring E is locked or secured to a bracket J. This bracket
carries a table or bed plate K forming a bed or stop for the end of the bottle neck
to rest upon or against, while manipulating the tool.
On this table or bed plate rotates a mandrel L prevented from leaving the same
by a flange g fitting a recess in the lower side of the table or bed plate.
This mandrel is adapted to fit the required bore of the neck of the bottle jar or
like receptacle to be operated upon. Slots h. h are formed in the sides of the
mandrel as shewn and through these protrude (or can be retracted) a pair of cutting
dies, M. M'. These dies are normally drawn inwardly by a spring or springs N SO
that they may come flush with, or slightly project from the outer surface of the
maudrel L.
Their inner surfaces are coned bevelled or sloped so that the tongue or bolt I can
introduce itself between them as the yoke advances and cause the pair of dies M M¹
to protrude from the mandrel and bite into the heated bottle neck or the neck of

page_text: the jar or analagous article being treated due to the clamping jaws C. C¹ being forced
together. Those jaws C. C¹ are moulded to form the exterior of the neck.
On grasping the instrument by one or both hands firmly the heated bottle or
receptacle can now be rolled to and fro on the table or surface provided and the
dies M M cut the required grooves recesses or forms necessary on the interior of
the aforesaid neck the mandrel rotating with the body of the bottle or receptacle.
When finished the bottle or receptacle can be released by allowing the clamping
jaws C. C to open and so setting the bottle or receptacle free ready for annealing
and subsequently cooling.
0.0' are guides to prevent the bottle neck slipping on the table.
By this means we are enabled to produce mechanically stoppered bottles jars or
"articles in a cheap simple
like receptacles as distinguished from "cork-stoppered
and effective manner.
We make no claim to the form of bottle or stopper claimed but 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 :—
I. In a tool or instrument for forming grooves or recesses in the necks of bottles,
jars or like receptacles to receive specially adapted internal stoppers, the combination
of a pair of shaped clamping jaws to receive the neck of the bottle or like receptacle
and operated so as to approach or recede from each other-spring united levers-
a rotating mandrel carried by the frame of the tool and having cutting or moulding
dies arranged to operate from the same, and a yoke or device worked from the said
spring levers so that the said yoke or device may in turn force on the said cutting
or moulding dies when the bottle or like receptacle is placed on the mandrel and
the same be rotated to cut or form the grooves or recesses in the heated or softened
article as described.
II. The general construction and arrangement of tool or apparatus substantially
as and for the purposes hereinbefore specified and illustrated in the accompanying
drawings.
