Year: 1876

page_text: LETTERS PATENT to James Greene Hatton, of Manchester, in the County of
Lancaster, for the Invention of "AN IMPROVED PACKING MATERIAL."
PROVISIONAL SPECIFICATION left by the said James Greene Hatton at the
Office of the Commissioners of Patents on the 29th January 1876.
JAMES GREENE HATTON, of Manchester, in the County of Lancaster.
IMPROVED PACKING MATERIAL."
" AN
The object of this Invention is to form an improved packing material which is at
the same time strong and flexible and also impervious to water, oil, or other liquids,
and to tar and other similar fluid and semi-fluid substances.
The Invention consists principally in combining a certain substance known as
vegetable parchment" with cotton or other cloth, or other fibrous woven or textile
inaterial, or with ordinary brown or other paper, by. means of paste or other
adhesive substance or compound, for the purpose of strengthening the same and
rendering it more supple and pliable.
Vegetable parchment is a preparation of paper made from vegetable fibre and
submitted to the action of a dilute solution of alum and oil of vitriol and other
chemical processes which render the paper insoluble, impervious to water, oil, or tar,
and cause it to resemble parchment in its appearance and toughness.
The improved packing material made by the combination of this substance with
cloth or with other fibrous material in a woven or unwoven state by means of paste
or other adhesive material may be used for all kinds of packing purposes, but it is
especially applicable for lining cases, bales, boxes, or bags for exportation of goods
of all kinds, and if the joints are made with a waterproof cement or mixture the
said cases, bales, boxes, or bags will be found to be perfectly impervious to oil,
water, tar, and other fluid or semi-fluid substances, which is a very great desideratum
on ship board.
The improved packing material will also protect goods from being discolored or
impregnated by the use externally for packing purposes of tarpauling or other such
articles of which oil or tar form the chief protecting ingredients.

IMPROVED PACKING MATERIAL."

The object of this Invention is to form an improved packing material which is at
the same time strong and flexible, and also impervious to water, oil, and other
liquids, to damp or moisture, and to tar and other similar fluids and semi-fluid

The Invention consists principally in combining a certain substance known as
vegetable parchment" with Hessian canvas, cotton, or other cloth, or with other
fibrous woven or textile material, or with ordinary brown or other paper, by means
of paste or other adhesive substance or compound, for the purpose of strengthening
the same and rendering it more supplé and pliable.
«
Vegetable parchment" is a preparation of paper made from vegetable fibre and
submitted to the action of a dilute solution of alum and oil of vitriol and other
chemical processes, which render the article insoluble, impervious to water, moisture,
oil,, or tar, and cause it to resemble parchment in its appearance and toughness.
The improved material for packing made by the combination of this substance
with cloth or other fibrous material in a woven or uneven state, or with brown or
other paper, by means of paste or other adhesive material, thay be used for all kinds
of packing purposes, but it is especially applicable for lining cases, bales, boxes, tea
chests, coffee, sugar, or other bags, for exportation or importation of goods or
produce of all kinds, and if the joints of the said linings, bags, &c. are made with a
waterproof cement or mixture the said cases, bales, boxes, chests, or bags will be
found to be perfectly impervious to water, oil, or other fluid and seini-fluid
substances (which is a very great desideratuin on ship board), and may be used with
advantage in lieu of the tin or zinc linings or cases hitherto employed for such
purposes.
The improved packing material will also protect goods from being discolored,
stained, or impregnated by the use externally for packing purposes of tarpauling or
other such articles, of which oil, pitch, or tar form the chief protecting ingredients.
It may also be used for lining damp walls, for lining hats, caps, and bonnets, to
prevent the passage of grease, for making dress preservers, to prevent the discolora-
tion of dresses by the effects of perspiration, also for making waterproof postage
envelopes, luggage labels, and for a variety of other useful purposes where
imperineability combined with pliability and toughness is desired.
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 would remark in conclusion that I claim as my Invention, the manufacture
and use for the above named purposes of a packing material formed by the com-
bination of a substance known as vegetable parchment with Hessian canvas,
cotton or other cloth, or other fibrous woven or textile material, or with ordinary
brown or other paper, by means of a paste or other adhesive substance or compound,
substantially as herein-before described.
In witness whereof, I, the said James Green Hatton, have hereunto set my
hand and seal, this Twenty-eighth day of July, in the year of our Lord One
thousand eight hundred and seventy-six.
