page_text: LETTERS PATENT to James Quin, of Leyland, in the County of Lan-
caster, for the Invention of "PROTECTING INDIA-RUBBER VALVES, TUBES,
AND OTHER LIKE ARTICLES FROM CHEMICAL ACTION.”
AND OTHER LIKE ARTICLES FROM CHEMICAL ACTION.”
Sealed the 16th March 1875, and dated the 12th November 1874.
PROVISIONAL SPECIFICATION left by the said James Quin at the
-
Office of the Commissioners of Patents, with his Petition, on the
12th November 1874.
I, JAMES QUIN, of Leyland, in the County of Lancaster, do hereby
declare the nature of the said Invention for "PROTECTING INDIA-RUBBER
VALVES, TUBES, AND OTHER LIKE ARTICLES FROM CHEMICAL ACTION," to be as
follows:-
On the 6th day of January in this present year I obtained protection
for an Invention with this same title and for the same object, but could
not, within the time given for notice to proceed, satisfactorily develope
and test the durability and consequent value of my Invention.

page_text: There is a spirit or other chemical matter in most lubricating oils
which in a short time proves a solvent to india-rubber valves, and india-
rubber pipes or tubes may not be used for chemical purposes, because
all acids are antagonistic to it, as before used, and would destroy it in a
short time. My object therefore is to make the surfaces of these
articles impervious to such action without in the least injuring the
clasticity.
For valves and such-like articles I provide as required by the shape
and size an inside shape or groundwork of either "red" or "A floating
rubber," which is light and durable. These I coat or case with a mixture
of mineral and vegetable (same as used in my before-mentioned Inven-
tion), and in some instances with ground metal mixture in such
proportons as the nature and future use of the article may require.
I do not use cloth, as in my before-mentioned Invention, for the reason
of its non-elasticity and absorbent nature. I then place them in moulds,
and subject them to the usual heat for vulcanizing.
For pipes, tubes, and other such-like articles I provide an inside casing
of the same material, cased again inside with an inner case of chemical
resisting material, composed of foil or ground metal mixed with the
vegetable and mineral mixture, as before named.
The outer surface may or not be coated with the same, or with the
same material as the valves.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Quin in the Great Seal Patent Office on
the 9th April 1875.
○ TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
QUIN, of Leyland, in the County of Lancaster, send greeting.

For pipes, tubes, and such-like articles I provide similar groundwork
of red or floating A, cased with and by a similar material and in a
'similar manner, after which they are vulcanised in the usual way.
Having described my Invention and the way in which it is applied
with the several articles so used and applied, I desire it to be distinctly
understood that I do not confine myself to any particular method of
coating or casing, nor to the exact mixtures of casing, as many variations
may be made in detail without deviating from the principle or main
features of my Invention, which consists of coating good elastic india-
rubber valves, pipes, or tubes, and other like articles with a material
rendering them impervious to chemical action, substantialy as and for
the purposes herein-before set forth.
In witness wherefore, I, the said James Quin, have hereunto set.
my hand and seal, this Sixth day of April, in the year of our
Lord One thousand eight hundred and seventy-five.

Engineer and. Patent Agent,
