do hereby declare the nature of said invention for IMPROVEMENTS IN THE
MANUFACTURE OF ELASTIC COMPOUNDS " to be as follows:-
My invention relates to the manufacture of elastic, compounds designed to be
used for most of the purposes to which India rubber or India rubber compounds is
or are applied; also as a substitute, in many cases, for gutta percha.
My invention consists essentially in the employment of sulphur and linseed or
other vegetable oil, and in causing the same to combine, under the influence of
a high degree of heat; but other substances are added' thereto with considerable
advantage as hereinafter indicated to adapt the compounds to the particular uses
for which they may be required.

A compound of considerable elasticity, and suitable for a variety of purposes, is

Cotton, Rape, or Poppy, oil may be used instead of Linseed oil, but I prefer the
latter; and gum kowrie, or copal, or any other resinous gum may be used instead
of ordinary resin, if preferred.
I employ resin in the compound for the purpose of increasing elasticity and
facilitating the combination; and slate for preventing stickiness and for reducing
the cost. When I desire to make a specially hard compound I add to the above
ingredients: coal pitch, or sand, chalk, or some other similar or suitable earthy
substance which will have the desired. effect, the proportion varying according to
the degree of hardness required.
In making my compounds I take the sulphur and oil and place them together in
a suitable vessel and subject them to heat, therein. They should be heated to
a temperature of from 300° to 500° Fahrenheit and kept at this temperature until
the mass has become of the desired consistency which will vary according to the

It is to be understood that although certain approximate proportions have
been given above they must necessarily vary within considerable limits according

I, JOHN JEYES, of Richmond House, Plaistow, in the County of Essex,
Chemist, do hereby declare the nature of my invention for "IMPROVEMENTS, IN
THE MANUFACTURE OF ELASTIC COMPOUNDS." and in what manner the same is
to be performed; to be particularly described and ascertained in and by the
following statement:-
2.3.
My invention relates to the 'manufacture of elastic compounds, which can
be advantageously used for most of the purposes to which india-rubber or
compounds thereof are usually applied, and which will, in some cases, serve
as a substitute for gutta-percha.
In carrying my invention into practice, I combine sulphur, linseed or other oil
or any suitable fat, and resin, or a resinous gum or compound. In some cases,
I add slate or other substances to this mixture, with considerable advantage,
as hereinafter specified to adapt my compounds to the particular uses for which
they may be required.
"
I make my compounds in the following manner, viz:-I take the sulphur and
the oil or fat and place them together in a suitable vessel, in which I subject them
to a high degree of heat, say from 300° to 500° Fahrenheit. They should be kept
at this temperature until the mass has become of the desired consistency, which
will vary according to the uses to which the compound is to be applied. When the
mass is in a perfectly liquid state, I add the resin and the slate or other ingredients
if such are desirable or necessary.
A compound of considerable elasticity and suitable for a variety of purposes
is manufactured, according to my invention, by combining the following ingredients
in, or about in, the proportions named, that is to say :-
Sulphur (preferably in the form of powder)
Linseed or other vegetable oil
Resin
75 parts by weight..
->
200 parts by weight:
-
50 parts by weight.
Slate or French chalk (reduced to a fine powder) 100 parts by weight.
Cotton, rape, poppy or other oil or any suitable fat may, as above stated, be used
instead of the linseed oil, but I prefer the latter; moreover, gum kawrie or copal
or any other resinous gum or compound may be used instead of ordinary resin if
preferred.

page_text: I employ resin in the compound for the purpose of increasing its elasticity, and
facilitating the combination of the ingredients, and I use slate or French chalk to
prevent stickiness of the product and to reduce its cost. -
When I desire to make a specially hard compound, I add to the above named
ingredients coal-tar or sand, chalk or some other similar or suitable earthy substance
which will produce the desired effect, the proportions varying according to the
degree of hardness required.
I wish it to be understood that, although I have stated approximately the
proportions which I employ, yet I do not limit myself to such proportions, as they
must necessarily vary within considerable limits according to the desired result.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The manufacture of elastic compounds by the combination of sulphur, linseed or
other oil or fat, and resin or a resinous gum or compound, with or without slate,
French chalk, or other substances, for the purposes above specified.
