IMPROVEMENTS IN TOOLS OR APPARATUS EMPLOYED IN THE MANUFACTURE OF BOTTLES
Year: 1879

page_text: LETTERS PATENT to Charles James Wade and John William Dobson, both of
Barnsley, in the County of York, for the Invention of "IMPROVEMENTS IN
TOOLS OR APPARATUS EMPLOYED IN THE MANUFACTURE OF BOTTLES."
PROVISIONAL SPECIFICATION left by the said Charles James Wade and
John William Dobson at the Office of the Commissioners of Patents on the
8th November 1879.
CHARLES JAMES WADE and JOHN WILLIAM DOBSON, both of Barnsley, in the
County of York. "IMPROVEMENTS IN TOOLS OR APPARATUS EMPLOYED IN THE
MANUFACTURE OF BOTTLES."
Our Invention relates to tools or apparatus for forming an annular groove or
grooves or recesses in the interior of the necks of bottles simultaneously with the
formation of the exterior of the said necks, and it has reference to that description
of tools or apparatus for this purpose in which the annular groove or grooves or
recesses is or are produced by means of expanding dogs or dies working in and
through a slotted plug which is carried on a central rod or bar attached to the
spring tongs, the exterior of the neck being formed by the said spring tongs in the
usual manner.
In carrying out our Invention we employ two bell crank levers mounted
respectively upon two centres or fulcra in arms formed on or attached to the
central rod or bar; one arm of each of these levers carries one of the dogs or dies
whilst the other arm of each lever is formed with an inclined or cam slot with
which engages one of two pins on the shanks of the spring tongs, so that by the
act of closing the spring tongs the dogs or dies are protruded, and by releasing the
spring tongs the dogs or dies are withdrawn within the plug.
By means of our Invention great simplicity and economy of construction are
obtained, whilst the efficiency of the apparatus remains unimpaired.

by the said Charles James Wade and John William Dobson in the Great Seal
Patent Office on the 7th May 1880.
CHARLES JAMES WADE and JOHN WILLIAM DOBSON, both of Barnsley, in the
County of York. "IMPROVEMENTS IN TOOLS OR APPARATUS EMPLOYED IN THE
MANUFACTURE OF BOTTLES."
Our said Invention relates to tools or apparatus for forming an annular groove
or grooves or recesses in the interior of the necks of bottles simultaneously with the
formation of the exterior of the said necks, and it has reference to that description
of tools or apparatus for this purpose in which the annular groove or grooves or
recesses is or are produced by means of expanding dogs or dies working in and
through a slotted plug which is carried on a central rod or bar attached to the
spring tongs, the exterior of the neck being formed by the said spring tongs in the
usual manner.
In carrying out our said Invention we employ two bell crank levers mounted
respectively upon two centres or fulcra in arms formed on or attached to the
central rod or bar; one arm of each of these levers carries one of the dogs or dies,
whilst the other, arm of each lever is formed with an inclined or cam slot or
groove with which engages one of the two pins on the shanks of the spring tongs,
so that by the act of closing the spring tongs the dogs or dies are protruded, and
by releasing the spring tongs the dogs or dies are withdrawn within the plug.
By means of our said Invention great simplicity and economy of construction are
obtained, whilst the efficiency of the apparatus remains unimpaired.
And in order that the said Invention may be fully understood we shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the several Figures on the annexed Sheet of Drawings, the same letters of reference
indicating corresponding parts in all the Figures.
Figure 1 of the accompanying Drawings represents an elevation of a bottle tool
constructed according to our said Invention, the spring tongs being represented as
in their open position with the expanding dogs or dies withdrawn within the
plugs; Figure 2 is an elevation taken at right angles to Figure 1, a portion of the
near shank of the tongs being assumed to have been broken away or removed so
as to render the expanding dogs or dies visible; Figure 3 is a sectional elevation
taken in the same direction as the elevation Figure 1, but with the spring tongs
represented as in their closed position, and the expanding dogs or dies protruded.
A is the central rod or bar connected at one end to the bow a of the spring
tongs B, B, and carrying at its opposite end the plug C for forming the interior of
the neck of the bottle, the said plug being slotted at b for reception and operation
of the expanding dogs or dies D, D, by the aid of which the annular groove in the
neck is produced, whilst the extremities of the shanks b¹, b¹, of the tongs B, B, are
Buitably constructed at c, c, for the formation of the exterior of the neck, all as in
the usual manner.
According to our said Invention we employ two bell crank levers E, E, mounted
respectively upon two centres or fulcra d, d, in arms F, F, formed on or attached to
the central rod or bar A; one arm e of each of the bell crank levers E, E, carries one
of the dogs or dies D, D, whilst the other arm e¹ of each lever E is formed with an
inclined or cam slot f, with which slots respectively engage pins g on the
shanks b', b', of the tongs B. In the act of closing the spring tongs B the
levers E, E, under the action of the pins g, g, and slots f. f, are turned upon their
centres or fulcra d, d, and the dogs or dies D, D, are protruded. This position of
the parts is represented in Figure 3. By releasing the spring tongs B the levers E, E,
are returned to their original position, and the dogs or dies D, D, are withdrawn
within the plug C, as indicated in Figure 1.

page_text: It will be understood that the dogs or dies should be made of a form corre-
sponding to the number, shape, and nature of the grooves or recesses to be produced
in the interior of the neck of the bottle.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and original,
and therefore claim as the Invention secured to us by the herein before in part
recited Letters Patent is,-
In tools or apparatus of the description herein set forth employed in the manu-
facture of bottles, carrying the expanding dogs or dies on bell crank levers which
are mounted on centres or fulcra on the central rod or bar or on an attachment
thereto, and are provided with inclined or cam slots or grooves, with which engage
pins carried by the shanks of the spring tongs, all substantially as and for the
purpose herein before described.
In witness whereof we, the said Charles James Wade and John William
Dobson, have to this our Specification set our hands and seals, this Fifth
day of May, One thousand eight hundred and eighty.
