pursuance of the conditions of the Letters Patent.)
PROVISIONAL, SPECIFICATION left by the said Richard Condy at the Office
of the Commissioners of Patents on the 9th January 1880.
RICHARD CONDY, of No. 15, Garlick Hill, in the City of London. "A NEW OR
IMPROVED WATERPROOF COMPOUND TO BE USED IN CONJUNCTION WITH OR AS A
SUBSTITUTE FOR LEATHER, AND FOR VARIOUS USEFUL PURPOSES."
The object of this Invention is the production of a compound or material in the
following manner :-
I. I take scrap leather and waste vegetable fibre, such as the spent bark of the
oak, pine, or birch that has been used for tanning purposes, or the waste fibre from
the hemlock that has been similarly used, or fibres from the rind of the walnut,
pomegranate, and similar fruit, or the waste fibre that is left after making infusions
for various purposes; and in some cases I may add a certain quantity of wood
shavings, by preference shavings of wood having a strong fibre or having resinous
properties.
II. I take also the waste of shoddy or mungo, tailors' cuttings, and the sweepings
from wool or cotton factories, or any or some of such substances. When the
vegetable or animal matter requires opening I pass it through a scutcher or similar
machine for that purpose, and I may then, or previously if necessary, subject the
fibrous mass to the action of soda in solution to cleanse it from extraneous matters
and render it more easily capable of being combined with the other materials
hereinafter mentioned. I well mix the whole together.
III. Having now obtained a mass which shall form the body of the compound,
and from its fibre possess the requisite strength, I next take other substances, which
when combined therewith shall cause the fibrous mass to bind together or cohere.

page_text: I take a certain quantity of glue, isinglass, gelatine, or horn shavings, or triturated
horn cuttings, and I take resinous matter, such as coarse unpurified lac, with
artificial or natural asphaltum or bitumen, and I take a mixture formed by
triturating caoutchouc with petroleum until it becomes a creamy adhesive mass.
Of the substances named having made my selection I mix them intimately together
in some suitable vessel, using, if necessary, heat until they form an adhesive liquid
or mixture, into which is introduced the fibrous mass hereinbefore mentioned (I.
and II.), and by stirring I form the whole into a stiff fibrous paste.
IV. The paste thus made is by suitable means passed through or between
rollers, and thereby pressed into sheets of the thickness required, which sheets are
afterwards air or stove dried.
V. Instead of making the mixture into sheets I may press it into any desired
form in moulds. When the articles are formed in this manner I may add to the
mixture some steatite asbestos or talc.
VI. I have not herein stated the quantities of the ingredients used, as they may
be varied according to the purposes for which the compound is required to be
applied, and where much animal fibre or matter is used I propose in some cases to
introduce into the ingredients some tannin or tannic acid.
