PROVISIONAL SPECIFICATION left by the said John Keil Tullis at the Office
of the Commissioners of Patents on the 25th July 1883.
JOHN KEIL TULLIS, of Glasgow, in the County of Lanark, North Britain,
"IMPROVEMENTS IN VALVES OR BUCKETS AND ANALOGOUS APPARATUS SUITABLE
FOR PUMPS OR OTHER MECHANISM
"
This Invention relates to Improvements in valves or buckets and analogous
apparatus suitable for pumps or other mechanism.-The Invention consists in
constructing the said valves or buckets of cotton canvas, fabric, solid cotton woven
fabric, camel-hair woven fabric, ör fabric of linen, hemp or jute, either in plies or
solid woven, or of fabric of woollen, hair, textile or animal fibres or of tough grass
with Gutta Percha or gum or India rubber; or of India rubber and cloth or India
rubber with cloth and leather or felted material or paper and cloth.-Any of these
materials either singly or mixed with any one or more of the others herein before
mentioned are or may be further treated by being soaked in boiled linseed oil
or other equivalent material, and may be either formed in one thick ply or of
several plies sewn together with thread of cotton or other equivalent material or
they may be sewn with metallic wire or held together with studs of metal or other
suitable material,

IMPROVEMENTS IN VALVES OR BUCKETS AND ANALOGOUS APPARATUS SUITABLE
FOR PUMPS OR OTHER MECHANISM"
My said Invention relates to improvements in valves or buckets and analogous
apparatus suitable for pumps or other mechanism.-My said improvements consist
in constructing the said valves or buckets. of the fabrics and in the manner herein-
after described.-These fabrics may either be worked up in one thick ply or of
several plies sewn together with thread of cotton, flax or other equivalent material
or they may be sewn with metallic wire or held together with studs of metal or
other suitable material.
And in order that my said Invention may be properly understood I now
proceed more particularly to set forth the system, mode or manner in or under
which the same is or may be used or practically carried into effect that is to
say:
3> <
In carrying out my present improvements I construct the said valves or buckets
of either of the fabrics known as "cotton canvas fabric," "solid cotton woven
fabric," camel hair woven fabric," or fabric of linen, hemp or jute either in plies
or solid woven, or of fabric of woollen, hair, textile or animal fibres or of tough
grass with gutta percha or gum or India rubber; or of India rubber and cloth,
or India rubber with cloth and leather or felted material or paper and cloth.-
Any of these materials either singly or mixed, that is to say, constructed of any
combination of the fibres comprising the said fabrics separately, are or may be
further treated by being soaked in boiled linseed oil or any other oil having
equivalent properties, and may be either formed in one thick ply or of several
plies sewn together with thread of cotton, flax, or other equivalent material or
they may be sewn with metallic wire or held together with studs of metal or
other suitable material.
In applying these Improvements to pump buckets or valves which in working
undergo much flexure I insert into the said material plies of wire-gauze or thin
metallic plates or strips of thin sheet metal, or wires so as to toughen the said
inaterial and ensure it against fracture at or about its points or lines of flexure.
Having now described and particularly ascertained the nature of my said
Invention and the system, mode or manner in or under which the same is or may
be used or practically carried into effect, I would observe in conclusion that what
I consider to be novel and original and therefore claim as the invention secured
to me by the hereinbefore in part recited Letters Patent is :-
First. The construction of valves or pump buckets and other analogous apparatus
of the fabrics known as "cotton canvas fabric," "solid cotton woven fabric,".
"camel hair woven fabric," or fabric of linen, hemp or jute either in plies or solid
woven, or of fabric of woollen, hair, textile or animal fibres, or of tough grass
with gutta percha or gum or India rubber, or of India rubber with cloth and
leather or felted material or paper and cloth substantially as hereinbefore set
forth.

Clause with layers of wire gauze, thin metallic plates or strips of thin sheet metal
or wires substantially as and for the purposes herein before set forth.
In Witness Whereof I, the said John Keil Tullis have hereunto set my hand
and seal this seventeenth day of January in the year of our Lord One thousand
eight hundred and eighty four.
