LETTERS PATENT to James Quin, of Leyland, in the County of Lan-
caster, for the Invention of “IMPROVEMENTS IN THE MANUFacture of
BELTING FOR DRIVING MACHINERY."
PROVISIONAL SPECIFICATION left by the said James Quin at the
Office of the Commissioners of Patents, with his Petition, on the
27th December 1872.
I, JAMES QUIN, of Leyland, in the County of Lancaster, do hereby
declaro the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF BELTING FOR DRIVING MACHINERY," to be as follows:-
This Invention relates to the manufacture of that class of belting made
from a combination of woven fabric (cotton duck) and india-rubber, and
consists principally of a method of manufacture whereby such belting
may be made and vulcanized in any required length, say from one foot
to six hundred feet at a time, such belting being thereby formed square
at the edges and smooth on the surface. In the ordinary method such

page_text: belting is made only in lengths from nine to twelve feet long at a time,
by taking pieces of "duck" of suitable length and width, saturating
them with the rubber, and folding to about the width required, after
which a piece of sheet rubber is folded round outside and joined at the
edges. It is then placed in a metal mould, and pressed and vulcanized,
the length of the piece of belting capable of being produced being
limited to the length of the metal mould.
According to my improved method the "duck," saturated with india-
rubber as before, is only cut into strips of sufficient breadth when folded
to make a belt of the required width, but is left the whole length of
the piece of "duck." This is folded by hand and covered with sheet
rubber as before, and it is then passed through a metal die, which is kept
well supplied with a suitable lubricant, and which smooths and polishes
the surface, and forms the edges square at the same time. As it issues
from this die it is coiled on to a revolving cast-iron drum a strip of thin
metal (zinc by preference) being at the same time coiled up therewith,
so as to separate the folds and prevent the surfaces from adhering, and at
the same time to conduct the heat to the centre of the belting during
the subsequent operation of vulcanizing. This cast-iron drum with the
belting coiled thereon, and the zinc laid between each coil, as above-
described, is then removed and put into the boiler or vessel, and vul-
canized in the usual manner, after which it is taken and uncoiled, when
it will be found to be quite smooth on the surface and square at the
edges, besides being more pliable than the ordinary pressed belting.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 21
filed by the said James Quin in the Great Seal Patent Office on
the 27th June 1873.
TO ALL TO WHOM THESE PRESENTS' SHALL COME, I, James ¨¦
QUIN, of Leyland, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 8
Letters Patent, bearing date the Twenty-seventh day of December, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said James Quin, Her special
license that I, the said James Quin, my executors, administrators, 38

and assigns, or such others as I, the said James Quin, 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
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF BELTING FOR DRIVING MACHINERY,' upon the condition (amongst
others) that I, the said James Quin, my executors or administrators,
by an instrument in writing under my hand and seal, should par-
ticularly 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 James Quin, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say):—
This Invention relates to the manufacture of that class of belting made
from a combination of woven fabric (cotton duck) and india-rubber, and
consists principally of a method of manufacture, whereby such belting
may be made and vulcanized in any required length, say from one foot
to six hundred feet at a time, such belting 'being thereby formed square
at the edges and smooth on the surface. In the ordinary method such
belting is made only in lengths from nine to twelve feet long at a time
by taking pieces of "duck" of suitable length and width, saturating
them with the rubber, and folding to about the width required, after
which a piece of sheet rubber is folded round outside, and joined at the
edges. It is then placed in a metal mould, and pressed and vulcanized,
the length of the piece of belting capable of being produced being
limited to the length of the metal mould.
According to my improved method, the "duck" saturated with the india-
rubber as before, is only cut into strips of sufficient breadth when folded
to make a belt of the required width, but is left the whole length of the
piece of "duck." This is folded by hand, and covered with sheet rubber
as before, and it is then passed through a metal die which is kept well
supplied with a suitable lubricant, and which smoothes and polishes the
surface, and forms the edges square at the same time. As it issues

page_text: from this dic it is coiled on to a revolving cast-iron drum, a strip of thin
metal (zinc by preference) being at the same time coiled up therewith,
so as to separate the folds and prevent the surfaces from adhering, and
at the same time to conduct the heat to the centre of the belting during
the subsequent operation of vulcanizing. This cast-iron drum with the'
belting coiled thereon, and the zinc laid between each coil, as above-
described, is then removed and put into the boiler or vessel, and vul-
canized in the usual manner, after which it is taken and uncoiled, when
it will be found to be quite smooth on the surface and square at the
edges, besides being more pliable than the ordinary pressed belting.
Such being the nature and object of my said Invention, I will now
proceed to describe more in detail the manner in which the same is to
be or may be performed or carried into practical effect; and in order that
the same may be clearly understood I have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures
and letters of reference corresponding with those in the following
explanation thereof.
In the annexed Drawing Fig. 1 is a vertical section of the whole
apparatus; Fig. 2 is a side elevation; and Fig. 3, a front view of the
pressing part of the apparatus; Fig. 4 is an end view, and Fig. 5, a
front view of the coiling on drum.
a, a, represents the coil of belting made as above-described, of duck
saturated with india-rubber, and coated with sheet rubber on the outside.
The belting thus formed, instead of being pressed in a metal mould is
drawn through a die which may be either a fixed metal die kept well
supplied with a suitable lubricant, or (which is preferable) may be
formed of two rollers b, b, and c, c, mounted in suitable bearings in a
frame d, d. The upper roller b, b, (to which the requisite pressure is
given by means of screws e, e,) is provided with a boss f, f, (see detached
views, Fig. 6), and the lower roller c, c, is furnished with a fixed
collar g, g, and a movable collar h, h, to accommodate the die rollers to
different widths of belting. On leaving the die or die rollers the
belting a, a, proceeds to the cast-iron coiling drum i, i, which is mounted
in a suitable carriage k, k, running upon rails 1, 1. This drum is
provided with a fixed flange m, m, and two movable flanges n, n, so as
to suit different widths of belting, and above it is mounted a drum o, o,
carrying a coil of thin metal p, p, (zinc or brass) which is coiled up

page_text: therewith, so as to separate the folds of the belting, and prevent the
adhesion of the surfaces. As soon as one length of belting a, a, with its
metal strip p, p, has been coiled on to this drum, the latter is shifted
laterally, and another length drawn through the die or rollers, and coiled
on to the drum on the other side of the fixed flange m, m. The
drum o, o, with its shaft and standards q, q, is then removed, and the
drum m, m, with its two lengths of belting and metal coiled as above-
described, is pushed forward into the boiler and vulcanized in the usual
manner, the metal coils not only serving to prevent the surfaces of the
rubber from adhering, but also to conduct the heat equally through the
whole mass or coil.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I wish it to be understood that I
claim as my Invention the manufacture of belting for driving machinery
in the manner and by means of the apparatus herein-before particularly
described, and more especially I claim the manner of coiling the lengths
of belting on to drums with thin metal between cach layer, and vul-
canizing the same, as described.
In witness whereof, I, the said James Quin, have hereunto set my
hand and seal, this Twenty-sixth day of June, in the year of our
Lord One thousand cight hundred and seventy-three.
