Year: 1871

page_text: LETTERS PATENT to William Brooke, of Leeds, in the County of
York, for the Invention of "AN IMPROVED METHOD OF FORMING OR
MAKING IN THE NECK OF BOTTLES A GROOVE OR SOCKET FOR THE
RECEPTION OF WASHERS, AND IN MACHINERY OR APPARATUS
THEREFOR."
EMPLOYED
Sealed the 8th March 1872, and dated the 16th September 1871.
PROVISIONAL SPECIFICATION left by the said William Brooke at the
Office of the Commissioners of Patents, with his Petition, on the
16th September 1871.
I, WILLIAM BROOKE, of Leeds, in the County of York, do hereby
declare the nature of the said Invention for "AN IMPROVED METHOD OF
FORMING OR MAKING IN THE NECK OF BOTTLES A GROOVE OR SOCKET FOR THE
RECEPTION OF WASHERS, AND IN MACHINERY OR APPARATUS
THEREFOR," to be as follows:-
EMPLOYED
My Invention consists in the method of forming or making in the
neck a groove or socket for the reception of washers formed of cork or
other suitable elastic material, and in the machinery or apparatus

page_text: employed therefor; it is particularly applicable to the manufacture of
glass bottles, but may also be employed for a like purpose in the
manufacture of bottles formed of clay or other plastic substances. For
the purpose of forming the internal socket or groove I employ the
forming tool which has hitherto been used in forming the necks, and
which consists of a pair of spring tongs having the dies for forming
the exterior at the extremity of the legs. Mounted and fixed centrally
between the legs there is a rod or carrier, to the end of which is
attached a taper mandril of suitable dimensions. The mandril works as
a pivot during the operation of the dies on the exterior.
In combination with the above-mentioned tool I attach to the legs
another pair of dies which are formed so as to pass into the mandril
(which is made hollow for their reception) and through side holes to the
exterior. These dies are brought into operation simultaneously with
the exterior dies, that is to say, when the exterior dies are closed
(by pressure from the hand of the attendant) on to the neck of the
bottle the interior dies are forced outwards through the side holes in
the side of the mandril to any length, according to the depth required
for the groove or socket.
Previous to the operation being performed, the required portion of
the neck is brought to a molten or soft state, and the operator
proceeds in the same manner as when forming the exterior part of
the neck.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Brooke in the Great Seal Patent Office 2
on the 16th March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROOKE, of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of September, in the 3
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Brooke, Her
special licence that I, . the said William Brooke, my executors,
administrators, and assigns, or such others as I, the said William 3

Brooke, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED METHOD OF FORMING OR MAKING IN THE NECK
OP BOTTLES & GROOVE OR SOCKET FOR THE RECEPTION OF WASHERS, AND IN
MACHINERY OR APPARATUS EMPLOYED THEREFOR," upon the condition
(amongst others) that I, the said William Brooke, my executors or
administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Brooke, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the
accompanying Drawings, and to the letters of reference marked
thereon, that is to say :-
.

'
My Invention consists in the method of forming or making in the
neck a groove or socket for the reception of washers formed of cork or
other suitable clastic material, and in the machinery or apparatus
employed therefor; it is particularly applicable to the manufacture of
glass bottles, but may also be employed for a like purpose in the
manufacture of bottles formed of clay or other plastic substances.
For the purpose of forming the internal socket or groove I employ the
forming tool which has hitherto been used in forming the necks, and
which consists of a pair of spring tongs having the dies for forming the
exterior at the extremity of the legs. Mounted and fixed centrally
between the legs there is a rod or carrier, to the end of which is
attached a taper mandril of suitable dimensions. The mandril works
as a pivot during the operation of the dies on the exterior.
In combination with the above-mentioned tool I attach to the legs
another pair of dies which are formed so as to pass into the mandril
(which is made hollow for their reception) and through side holes to

page_text: the exterior. These dies are brought into operation simultaneously
with the exterior dics, that is to say, when the exterior dies are closed
(by pressure from the hand of the attendant) on to the neck of the
bottle the interior dies are forced outwards through the side holes in
the side of the mandril to any length, according to the depth required
for the groove or socket.
Previous to the operation being performed, the required portion of
the neck is brought to a molten or soft state, and the operator
proceeds in the same manner as when forming the exterior part
of the neck.
.
The manner in which this Invention is or may be performed or
carried into practice, will be more readily understood by reference to the
accompanying Sheet of Drawings.
Fig. 1 is a front elevation, Fig. 2 a side clevation, and Fig. 3 a plan
of the forming tool constructed according to my Invention.
Fig. 4 is a section of a bottle showing the internal groove or
socket in the neck of the same. For the purpose of forming the
internal groove or socket a (Fig. 4), I employ the forming tool as shown
in Figs. 1, 2, and 3, which in its simple form has heretofore been used
in forming the exterior part of the necks of bottles, and consists of a
pair of spring tongs e, e, having the dies b. Now, according to my
Invention I construct these tongs with a rod or carrier f, to the end of
which is attached a hollow taper mandril g of suitable dimensions. The
mandril g works as a pivot during the operation of the dies on the
exterior of the bottle; h, h, are another pair of dies which are secured
thereto by the nuts i. The dies h are bent as shewn so as to pass into
the mandril 9 and through holes in the sides thereof to the exterior.
These dies h are brought into operation simultaneously with the exterior
dies b, that is to say, when the exterior dies 6 are closed (by the
pressure from the hand of the attendant) on to the neck of the bottle,
the interior dies h are forced outwards through the side holes in the
mandril g to any required distance, as shown by dotted lines at 1 when
not in use, and no pressure is put on the dies h return into position 2
within the mandril g.
Having now described the nature of my said Invention, and the
manner in which the same is to be performed, I would remark in
conclusion, that I do not limit myself to the exact details, limits, and.

page_text: configuration of parts I have explained and shown, as the same may of
course be varied or modified without in any way departing from the
nature and principle of my Invention; but what I do claim and desire
to be secured to me by Letters Patent is,―
Firstly. The herein-before described mode or method of forming the
grooved interior of bottle necks simultaneously with the exterior of
bottle necks, by the employment of internal expanding dies in
combination with the present tongs for forming the exterior of
bottle necks.
Secondly. The combination of the exterior forming tool or tongs
and the internal expanding die arrangement substantially as described.
In witness whereof, I, the said William Brooke, have hereunto set
my hand and seal, this Fourteenth day of March, in the year of
our Lord One thousand eight hundred and seventy-two.
WILLIAM BROOKE. (L.S.)
