IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF PACKING MATERIAL, WHICH IS ALSO APPLICABLE FOR OTHER PURPOSES
Year: 1880

page_text: LETTERS PATENT to Edward Quin, of Leyland, near Preston, in the County of
Lancaster, for an Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
WATERPROOF PACKING MATERIAL, WHICH IS ALSO APPLICABLE FOR OTHER
PURPOSES."
PROVISIONAL SPECIFICATION left by the said Edward Quin at the Office of
the Commissioners of Patents on the 18th February 1880.
EDWARD QUIN, of Leyland, near Preston, in the County of Lancaster.
"IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF PACKING MATERIAL,
WHICH IS ALSO APPLICABLE FOR OTHER PURPOSES."
This Invention relates to the manufacture of an improved waterproof material
suitable for packing goods in cases for shipping abroad, but it may also be used as
a lining for ordinary paper on damp walls, or it may be printed upon and used as a
waterproof wall paper, and for a variety of other uses where a thin flexible water-
proof material is required.
The improved material is made by the combination of two layers of paper with
a central layer of cloth or woven fabric; the whole being cemented together with
india rubber solution or cement, and then submitted to a vulcanizing process.
The thickness of the paper and of the cloth or woven fabric will depend upon the
strength required and the particular purpose for which the waterproof material is
to be employed.
In manufacturing this improved waterproof material I employ a pair of calendering
rollers, mounted side by side close together in the same plane in a suitable frame.
On the outside of each of these rollers is supported a roll of paper, and above the
point where the rollers touch each other I mount the roll of clothì.
The paper from each roll passes over the calender roller next to it, and the two
are passed downwards between the nip of the rollers, the cloth passing also through
the centre perpendicularly between the two papers.
A quantity of india rubber solution or cement is now poured on each side of the
cloth, between it and the paper until it is nearly level with the top of the two
calendering rollers, the solution or cement being prevented from running over the
ends by means of two side plates or cheeks cut out to fit the upper circumference
D

page_text: of the rollers, the said side plates being made adjustable by means of screws or
racks to suit different widths of material.
The calendering rollers being now set in motion the cloth with the layer of
paper on each side will be drawn through, and will be perfectly cemented together
into one waterproof fabric as it passes between the rollers.
The pressure of the two calendering rollers may be regulated by means of springs
or screws, or by both combined.
The waterproof material thus formed is now to be submitted to a vulcanizing
process by means of steam or by any other suitable known means, and it is then
ready for use.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Edward Quin in the Great Seal Patent Office on the 18th August
1880.

side plates being made adjustable by means of screws or racks to suit the different
widths of material. The calendering rollers being now set in motion the cloth with

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 performed or carried into
practical effect, I wish it to he understood that I clain as my Invention the
manufacture of waterproof packing material (applicable also for other purposes as
above mentioned) by the combination of two layers of paper with a central layer
of cloth or woven fabric, the whole being cemented together with india rubber
solution or cement, and submitted to a vulcanizing process, substantially as
herein before described.
In witness whereof, I, the said Edward Quin, have hereunto set my hand
and seal, this Seventeenth day of August, in the year of our Lord One
thousand eight hundred and eighty.
