"
I, EMMA ANNETTE VOILE, of Bidborough Street, St. Pancras, in the
5 County of Middlesex, do hereby declare the nature of the said Invention
for "AN IMPROVED MACHINE OR APPARATUS TO BE EMPLOYED IN THE MANUFACTURE
OF PONTEFRACT PIPES," to be as follows (that is to say)
My Invention has reference to the improved construction of the
machinery or apparatus for facilitating the manufacture of Pontefract
pipes or sticks from the saccharine cake or substance, whereby double
the number of the said Pontefract pipes are enabled to be produced at

page_text: one operation than by the system at present in use, at the same time
delivered direct from the machine in equal lengths and of uniform size,
and consists in employing for the above purpose two rows of dies or
holes in the forcing box or chamber arranged horizontally one above
the other in the outer end of the box, consisting of about sixteen dies or
countersunk holes in the lower row and fourteen in the upper one, placed
at a short distance apart from each other, in connection with which a
series of flat take-away boards are used to receive the Pontefract pipes
as they are forced through the dies by the action of the plunger within
the box worked by screw and hand wheel gear in the ordinary manner,
whereby each number of the said pipes carried forward upon the boards
are cut into equal lengths by a knife or otherwise and maintained in
continuous working order upon an endless cloth moving on rollers in the
bed or table, upon which the forcing box is mounted and secured in the
usual manner.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Emma Annette Voile in the Great Seal Patent
Office on the 18th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EMMA
ANNETTE VOILE, of Bidborough Street, St. Pancras, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of May, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Emma Annette Voile, Her
special licence that I, the said Emma Annette Voile, my executors,
administrators, and assigns, or such others as I, the said Emma
Annette Voile, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter 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 MACHINE OR APPARATUS TO BE EMPLOYED IN THE
MANUFACTURE OF PONTEFRACT PIPES," upon the condition (amongst others)

page_text: that I, the said Emma Annette Voile, 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 Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Emma Annette Voile, do hereby
declare the nature of my said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement and the Drawings therein referred to (that is
to say):
My Invention has reference to the improved construction of the
machinery or apparatus for facilitating the manufacture of Pontefract
pipe from licorice or other saccharine ingredients or compound sub-
stances, whereby double the number of the said Pontefract pipes are
enabled to be produced at one operation than by the system at present
in use, at the same time delivered direct from the machine in equal
lengths and of uniform size, and consists in employing for the above
purpose two rows of dies or holes in the forcing box or chamber arranged
horizontally one abové another in the front or closed end of the said box,
consisting of about sixteen dies or countersunk holes in the lower row
and fourteen in the upper one, placed at a short distance apart from each
other, in connection with which a series of flat take-away boards are
used to receive the Pontefract pipes as they are forced through the dies
by the action of the plunger within the box worked by screw and hand
wheel gear in the ordinary manner. Thus the said pipes are carried
forward upon the boards and cut into equal lengths at the intersections
by a knife worked by hand or otherwise and the whole operation main-
tained in continuous working order by means of an endless cloth moving
on rollers within the bed or table, upon which the forcing box is mounted
and secured.
And in order that my said Invention may be more fully understood
and readily carried into effect, I now proceed to describe the same by the
aid of the accompanying Drawings, reference being had to the letters
and figures thereon marked (that is to say)
:-
Fig. 1 represents a vertical front view of my improved machinery to
be worked by land for manufacturing Pontefract pipe into uniform

page_text: lengths of about ten inches through the medium of a double set of
countersunk circular dies formed in the face of the pressing box; Fig. 2,
a side elevation thereof; Fig. 3, a top or plan view; and Figures 4, 5,
and 6, enlarged detail portions of the same. In each Figure the same
letters of reference denote similar corresponding parts.
A, A, bed or table; B, B, pressing box, bolted or otherwise secured to
the said bed or table in manner shown; C, C, forcing plate or plunger
of rectangular form, fitting closely without packing within the said box
so as to powerfully compress the Pontefract paste or substance under
operation and force it out through the dies aforesaid; D, D, screw arm
working through a fixed nut or collar D' within suitable bearings in the
outer end of the box for actuating the plunger; E, E, hand wheel.
secured to the boss-head of the screw arm for giving revolving motion
to the nut; F, F, Pontefract paste or ordinary saccharine compound;
G, G, countersunk dies or holes arranged horizontally in the face plate-
of the box, through which the Pontefract substance is pressed out in the
form of pipes, as seen at H, H, in the accompanying Drawings; I, I,
flat ten-inch boards upon which the Pontefract pipe is received and
carried forward upon an endless cloth J, J, over rollers J¹ direct from
the pressing box to the end of the table for being subsequently removed
and again replaced by others in continuous succession; K, K, winch
handle for turning the rollers and enabling the speed to be suitably
adjusted to the discharging action of the machine; L, L, intersections in
the boards through which a knife is run so as to cut the pipes into ten-
inch lengths for being removed and finally dipped in a surface coating of
licorice and dried under heat as required.
In manufacturing Pontefract pipe by my improved machinery the
saccharine paste or compound in a plastic state is first placed in the com-
pressing box and then forced through the several dies by the screw action
of the plunger so as to form thereby thirty-two lengths of the said pipe-
and deposit each of them longitudinally upon the boards or trays to be
carried forward on the travelling cloth, and finally cut into ten-inch
lengths for. removal upon the boards and again replaced by others in
succession during the operation of the machine. Thus by the combined:
arrangement and employment of the double system of dies and mode of
filling the boards and removing the same a greater number of the said
pipes of uniform length and size can be manufactured with less labour
and expense than by the method at present in use,
*

page_text: In conclusion to the foregoing description, I would here briefly note
that the machinery instead of being worked by hand; as above described,
may be driven by steam power or otherwise modified and arranged so as
to unite and render the compressing, cutting, and other working parts of
the machinery self-acting.
Having now fully described and ascertained the nature of this my
said Invention, and the manner in which the same is to be performed
and carried into effect, I would have it clearly understood that I do not
by any means intend to confine myself to the precise details herein-
before set forth and described, as the same may be otherwise varied
without departing from the general principle of this my said Invention,
nor do I claim as new and of my said Invention the exclusive use of the
several parts, combinations, and processes herein-before described, except
when the same are employed in and for the purposes of my said Inven-
tion, which I hereby declare to consist in employing in the construction
of Pontefract pipe compressing machinery, a double set of dies in con-
nection with traversing boards or trays for producing and receiving the
Pontefract pipe, and facilitating the removal of the same from the
apparatus during the process of manufacture, in the manner and for the
purposes herein-before set forth and described.
In witness whereof, I, the said Emma Annette Voilc, have here-
unto set my hand and scal, this Sixteenth day of November,
in the year of our Lord One thousand eight hundred and seventy-
four.
