IMPROVEMENTS IN TOOLS FOR FORMING GROOVES IN BOTTLE MOUTHS
Year: 1885

page_text: We DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley, Glass Bottle
Manufacturer, and BENJAMIN STONER, of Bridge Street, Stairfoot, near Barnsley,
Mechanic, do hereby declare the nature of our said invention for "IMPROVEMENTS
IN TOOLS FOR FORMING GROOVES IN BOTTLE MOUTHS, to be as follows:
According to our present invention we form the plug or mandril (which enters
the bottle mouth) in two portions. The bottom portion consists of the swiller and
that part of the plug which forms the part of orifice or mouth of the bottle above
the groove. Through this bottom portion we hore or form a hole vertically but
somewhat out of centre with it. We then form the top portion of plug solid and
having a projection for cutting groove and also having a pin or spindle such pin or
spindle being however out of centre with it, and which pin or spindle works
through the eccentric vertical hole in bottom portion of plug. A portion of this
pin or spindle is screwed and a locknut is attached for better keeping it in its
place. Below this locknut we fix tightly on this spindle a small pinion wheel.
The bottom end of spindle works in a hole formed in a crossbar. To one handle
of the tongs we attach firmly by any suitable means a rack the other end of which
rack has a suitable slot which works in another setscrew attached to the other
handle of the tongs. The toothed portion of this rack engages the small pinion
wheel attached to spindle connected with top half of plug. The handles of tongs
are fitted with the usual dies for forming the outside of the bottle mouth. When
the bottlemaker closes these tongs to form the bottle mouth he causes the rack
attached to one handle to engage the pinion fixed on spindle and this so turns the
top portion of plug as to bring the projection for cutting groove into proper position
for doing this. Soon as this is done the bottlemaker releases his pressure on the
handles of tongs, thus causing the top portion of plug (by the reverse operation of
the pinion and rack as above referred to) to come clear of the groove and so that
the plug may be withdrawn from the bottle. The projection on top part of plug
may be varied in shape according to the class of groove that is required, and where
it is desired to form two grooves, two projections may be formed on top part of
plug. As will be well understood any other suitable mechanical equivalent may
be substituted for the rack and pinion motion. The top part of plug or mandril
may (where it can be suitably arranged) be made to work in two halves each half
carrying a separate projection and a separate eccentric spindle and these projections
may be so arranged as to work exactly opposite each other in the bottle mouth.

We DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley, Glass Bottle
Manufacturer, and BENJAMIN STONER of Bridge-street, Stairfoot near Barnsley,
Mechanic, do hereby declare the nature of our invention for IMPROVEMENTS IN
TOOLS FOR FORMING GROOVES IN BOTTLE MOUTHS, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:---
According to our present invention we form the plug or mandril (which enters
the bottle mouth) in two portions. The bottom portion consists of the swiller and
that part of plug which forms the top part of orifice or mouth of bottle above the
groove. Through this bottom portion we bore or form a hole vertically but
somewhat out of centre with it. We then form the top portion of plug solid and
having a projection for cutting groove, and also having a pin or spindle, such pin
or spindle being however out of centre with it; and which pin or spindle works
through the eccentric vertical hole in bottom portion of plug. A portion of the
pin or spindle is screwed and a locknut is attached for better keeping it in its
place. Below this locknut we fix tightly on this spindle a small pinion wheel.
The bottom end of spindle works in a hole formed in a crossbar. To one handle
of the tongs we attach firmly by any suitable means a rack, the other end of which
rack has a suitable slot which works in another set-screw attached to the other
handle of the tongs. The toothed portion of this rack engages the small pinion
wheel attached to the spindle connected with the half of plug. The handles of
tongs are fitted with the usual dies for forming the outside of the bottle mouth.
When the bottle maker closes the tongs to form the bottle mouth he causes the
rack attached to one handle to engage the pinion fixed on spindle, and this so
turns the top portion of plug as to bring the projection for cutting the groove into
proper position for doing this. Soon as this is done the bottle maker releases his
pressure on the handles of the tongs, thus causing the top portion of plug (by the
reverse operation of the pinion and rack as before referred to) to come clear of the
groove and so that the plug may be withdrawn from the bottle.
The projection on the top part of plug may be varied in shape according to the
class of groove that is required, and where it is desired to form two grooves, two
projections may be formed on top part of plug.
As will be well understood any suitable mechanical equivalent may be substituted
for the rack and pinion motion.
The top part of plug or mandril may (where it can be suitably arranged) be made
to work in two halves, each half carrying a separate projection and a separate
eccentric spindle, and these projections may be so arranged as to work exactly
opposite each other in the bottle mouth.

;
Referring to Figs. 1, 2, 3, and 4 the plug or mandril A which enters the bottle.
mouth is made in two portions c and d; the bottom portion d consists of the
swiller and the part d of plug A which forms the top part of orifice or interior
of mouth of bottle above the groove. Through the portion d of plug A a hole is;
formed and is situated a suitable distance from the centre or out of the centre of
the part d² of portion d. The top portion c of plug A is solid and has a suitable
cutter or projection f for cutting or forming the groove in the bottle mouth. This.
top portion c of plug A has also a pin or spindle g which is situated at a suitable
distance from the centre or out of centre of said portion of plug A. The said
spindle g works through or has a bearing in 'the hole e formed in portion d of
plug A.
The pin or spindle g is threaded at i and a locknut J is screwed thereon so as
to firmly secure and keep the rotating portion c with its spindle g from falling.
or moving away from portion d.. On the spindle g is also firmly fixed a small
pinion wheel K. The bottom end of the spindle g rests in a hole formed in the.
crossbar l.
j
To the handle mɩ of the tongs B one end of the rack O is firmly secured by
means of the set-screw n; the other end of said rack O works in or passes through
a slot formed by means of a fixing h, which is attached to the bandle q of the;
tongs B.
The toothed portion o¹ of the rack O engages the small pinion wheel K. The
part d' or swiller of plug A is attached to the bridge R by means of the screws
and the bridge R is connected to the tongs B by means of the standard S and
nuts t; t', t. The dies U U are secured to the ends of the handles m. and q by means
of the nuts v. v.
:
In forming the mouth of a bottle with a groove therein by means of our herein-
before described improved tool, the bottle maker places the portion c and part d² of
plug A into the unformed mouth of bottle; he then presses to the handles m and q of
the tongs B in the usual manner until they obtain the position shown at Fig. 3, during
which operation the movement of the handles m has caused the rack O to revolve.
the pinion K, and the pinion K being secured to the spindle the said spindle g
with the portion c of plug A has turned and so brought the cutter or projection f.
into a suitable position for forming the groove in the bottle mouth. (See Fig. 3.).
Then after the bottle maker has revolved the bottle in the ordinary manner a.

page_text: requisite number of times so as to form a satisfactory mouth, he releases his
pressure on the handles m and q and they spring apart, and the toothed portion o¹
of the rack O turns the pinion K in the reverse direction and thus brings the
portion c of plug A with its cutter f into position shown at Fig. 1 so that the
cutter and portion c of plug A becomes clear of groove formed in the bottle
mouth, in which position the said plug A may with facility be withdrawn from the
bottle mouth.
..:
1.
It will be easily understood that by means of the hole e being out of the centre
of the part d', and the stem or spindle g being also out of the centre of the
portion c, that the portion c with its cutter frotates eccentrically with the part d³,
so that when the handles m and q are pressed to and the rack and pinion motion
herein before described turns the portion ca suitable distance round the said
portion c with its cutter f obtains the position shown at Figs. 3 and 4; but when
the handles m and q are released they spring apart and the portion c with its
cutter turns back to the position shown at Figs. 1 and 2.
The projection or cutter f may be varied in shape so as to cut any desired form
of groove.
* 提
When it is required to form two or more grooves the number of cutters ƒ may
be increased accordingly.
As will be well understood, any suitable mechanical equivalent may be substi-
tuted for the rack and pinion motion for the purpose of rotating the portion c of
plug A simultaneously with the pressing to and releasing of the handles m and q
of the tongs B, for instance a similar arrangement of levers may be used as
hereinafter described.
:
Referring to Figs. 5, 6, 7 and 8 the top portion c of plug A is made in halves c¹
and c²; the half c¹ has a spindle g³, and the half c has a spindle g². The holes e¹ e²
through. which the spindles g¹ g³ pass are arranged opposite each other and at a
suitable distance from the centre of the part d' of portion d. A small lever w¹ is
secured to the spindle g¹ by means of the set-screw x¹, and a similar small lever wa
is secured to the spindle g2 by means of the set-screw x². The rods y¹ y³ connect
the levers ww³ to the handles m and q in manner shown at Figs. 6 and 7. The
guard or stay Z which passes through the slots h¹ h¹ prevents lateral oscillation of
the bridge R and the standard.
When the handles m and q are apart as shown at Fig. 6, the halves c¹ and c³ of
the plug A are closed as shown at Figs. 6 and 8, in which position the said
halves c¹ and c₁ together with the part d' of the plug A are pressed into the
unformed mouth of bottle; then the handles m and g of the tongs B are pressed
to until they obtain the position shown at Fig. 7.
•
The pressing to of the handles m and q causes the rods y¹ y² to turn the small
levers wwwhich being secured to the spindles g¹ g₁ turn said spindles also, and
the spindles g¹ g² being part of or made with the halves c¹ c², the said halves c¹ ca
necessarily turn as well; in thus turning, the said halves c¹ c with their
cutters fif obtain the position shown at Fig. 7. The tongs are held in this
position during the time the mouth of bottle is being formed in the ordinary.
manner.
After the mouth of bottle has been thus satisfactorily formed, the handles m
and q are released and the rods y¹ y pull back the levers w¹ w² and so turn the
halves cc with their cutters or projections f¹ f' back to position shown at Figs. 6
and 8 in which position the plug A may be easily withdrawn from the mouth of
bottle.
.
The holes ee being situated at a suitable distance from the centre of the part d'
of portion d and the spindles g1 92 being also placed out of the centres of the
halves cc, the said halves cle with their cutters f¹ f necessarily rotate eccen-
trically with the part d² of portion d of plug A so that they open (see Figs. 5 and 7)
and close (see Figs. 6 and 8) simultaneously with the pressing to and releasing of
the handles m and q of the tongs B.
