PROVISIONAL SPECIFICATION,
A Gelatinous Resilient Composition applicable for Wheel Tyres and
other purposes.
We, DANIEL FORBES, of 29, Victoria Street, Bristol, Art Dealor, and
JAMES SELDON WEYMOUTH, of 34, Alpha Road, Southville, Bristol, Paper
Stock Merchant, do horeby declare the nature of this invention to be as
follows:-
This invention consists in a gelatinous resilient composition which is adapted for
wheel tyres and for other purposes. The composition which constitutes this
invention is made up of the following ingredients, viz.; Glue, collodion, sulphuric
acid, glacial acetic acid, nitric acid, formic acid, alumn, sulphur, and sulphate of
barium.
In compounding the substance, the glue is first melted with water in the same
way as glue is ordinarily dissolved. "The sulphur and sulphate of barium, both
pulverized, aro then added. They may be added either together or separately and
without regard to order. The alum, as a saturated solution, is next added, or it
may be put in prior to the sulphur and sulphate of barium. The acids are added
last and they may be put in either separately or mixed and without regard to
order of addition. They aro put in cold. The ingredients having been thus put
together in a suitable vessel, the whole is stirred until thoroughly incorporated.
The composition will remain for a limited time in a fluid state and, while in this
condition, it is run into moulds or other receptacles in which it assumes its final
shape according to the purposes it is designed to be applied to. If designed for
use in a wheel tyre, the composition is charged into a tube of covering of india
rubber or canvas which, with the contained composition, constitutes the tyre.
Similarly, the composition is adapted for the padding of seats and for various other
purposes where resilience is necessary or desirable.
The composition fiually assumes a solid stato and possesses a high degree of
resilience and is further of a durable nature.
In compounding the substance the following approximate proportions give good
results, viz. Dissolved glue 76 %, and 3% of each of the other eight ingredients,
but these proportions may be somewhat varied without prejudicially affecting the
composition.
The degree of bardness of the composition is capable of regulation; by
reducing the proportion of glue and increasing the proportions of the other
ingredients to balance the reduction, the substanco is rendered harder. In its
harder state it is adapted for use as uncovered tyres and for insertion in the soles
of cricket, tennis, and other shoes, and for other purposes where corresponding
characteristics are required.
Softening the composition is effected by adding to the other ingredients, as
aforesaid, during the process of compounding, about 3% of glycerine or moro
according to the degree of softness required.

A Gelatinous Resilient Composition applicable for Wheel Tyres and
other purposes.
We, DANIEL FORBES, of 29, Victoria Street, Bristol, Art Dealer, and
JAMES SELDON WEYMOUTH, of 34, Alpha Road, Southville, Bristol, Paper
Stock Morchant, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention consists in a composition of a gelatinous nature and resilient
character. It is adapted for use as a cushion tyre for the wheels of cycles and
carriages. It is also adapted for use as a cushion for seats and for chair backs
and for other purposes where resiliency is necessary or desirable.
The composition which constitutes this invention, is composed of gluo, collodion,
sulphuric acid, glacial acetic acid, nitric acid, formic acid, alum, sulphur, and
sulphate of barium.
To produce the composition, the glue is first melted with water in the same way
as glue is ordinarily dissolved, that is to say, glue and water, in proportions varying
with the degree of stiffness or consistency required, are placed in a suitable vessel
and subjected to the action of heat and thus inelted. To the molted glue is then
added the sulphur and sulphate of barium, both having been previously pulverized.
They are added to the melted glue either together or separately, and either may
be put in the mixing vessel before the other. The alum, as a saturated solution, is
next added. It may, however, be added to the melted glue prior to the sulphur
and sulphate of barium. The collodion is then added, or at any prior time. The
acids are added last. They are put into the mixing vessel either separately and
without regard to order of addition, or they may be mixed together in a separate
vessel and added in the mixed condition. They are put in cold. The ingredients
having been thus put together, the whole is stirred until thoroughly mixed.
The composition, when thoroughly mixed, remains for a brief time in a fluid
state during which it is run into moulds or other receptacles in which it assumes its
final shape according to the purpose for which it is required. It finally solidifies,
and in this state it possesses resiliency in a high degree and is of a durable naturo.
When employed as a tyre for cycles and other vehicles, the composition is
preferably run into a tube of india-rubber, canvas, or other suitable material.
In compounding the substances, the following proportions give good results in
practice, viz. Dissolved glue 76 per cent., and 3 per cent. of each of the other
cight ingredients aforesaid. But we do not confine ourselves to these proportions
which may be varied within restricted limits without prejudicially affecting the
composition.
By reducing the proportion of dissolved glue and increasing the proportions of
the other ingredients to balance such reduction, the composition may be hardened
in varying degrees. When sufficiently hardened, the composition is fitted to be
moulded into tyres which can be used without a covering, and it is also fitted for
insertion between the soles of cricket, tennis, and like shoes.
Again, by the addition of glycerine to the other ingredients aforesaid during
the process of mixing, a softening effect is produced upon the composition, varying
with the quantity of glycerine added. About 3 per cent. of glycerine will produce
an appreciable degree of softening.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we deolare that what we
claim is :-
A gelatinons resilient composition for use, either covered or uncovered, to form

page_text: tyres for cycles and other vehicles and for use as seat and other cushions and for
other purposes; said composition consisting of dissolved glue, collodion, sulphurio
acid, glacial acetic acid, nitric acid, formic acid, alum, sulphur, and sulphate of
barium, mixed together in the proportions, approximately, of 76 per cent. of
dissolved glue, and 3 per cent. of each of the other eight ingredients, substantially
as hereinabove set forth.
