PROVISIONAL SPECIFICATION.
An Improved Elastic Filling more especially applicable for Cycle
Tyres, Cycle-handles, Cushions, and the like, and in the Method
of Manufacturing the same.
I, JULIUS DEBORDE, of 9 Hallesches Ufer, Berlin, S.W., in the Empire of Germany,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved filling or padding more especially intended
for use in tyres, saddle-cushious, and handles of velocipedes, but also for use in cushions
generally.
This filling substantially consists of a gelatinous or glutinous substance which has
been transformed into a spongy state.
In order to produce a filling material of this kind, a gelatinous substance consisting
of glue, a glutinous mixture, gelatine or similar matter, is liquefied by heating and is
in its liquid state converted into froth by beating stirring, by centrifugal action or the
like. This froth is filled into tubes, hollow cushions or the like consisting of leather,
indiarubber, oilcloth or similar substance and is solidified by cooling. After solidification,
this gelatinous or glutinous substance, presents an infinite number of hollow spaces
filled with air, whereby the elasticity of the substance, which in itself is already of an
elastic nature, is very considerably increased, while its weight is greatly reduced.
In order to prevent this gelatinous matter from hardening, glycerine is added in
case the same consists of glue or gelatine. Further to protect the product from
putrefaction, antiseptical substances may be added.
Instead of the product being directly pumped into the tubes, hollow-cushions or the
like, it may also be cast into appropriate moulds, and the cooled down and solidified
mass obtained may be subsequently provided with a suitable, tightly closing cover of
indiarubber, leather or the like.
The elasticity and the lightness of the articles thus stuffed or filled with frothy
gelatinous substances may be still further increased by means of small hollow india
rubber balls, india rubber tubes or other light and elastic bodies.
This frothy gelatinous substance produced in the manner described is especially
suitable as a filling for tyres, saddles and handles of velocipedes and more generally
for cushions of any kind. Such cushions are durable, will never harden and can be
produced at a comparatively small cost. A great advantage inherent in cushions of
this kind consists in their being good conductors of heat and that they will therefore,
by rapidly discharging the heat, received, be kept at a low temperature when used.

I, JULIUS DEBORDE, of 9 Hallesches Ufer, Berlin, S.W., in the Empire of Germany,
Merchant, 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 relates to an improved filling or padding more especially intended
for use in tyres, saddle-cushions, and handle bars of velocipedes, but also for use in
cushions generally.
This filling substantially consists of a gelatinous or glutinous substance which has
been transformed into a spongy or foamy condition by mechanical or other treatment.
In order to produce a filling material of this kind, a gelatinous substance consisting
of glue, a glutinous mixture, gelatine or similar matter, is liquefied by heating and is
in its liquid state converted into froth by beating, stirring, by centrifugal action or the
like. This froth is filled into tubes, hollow cushions or the like consisting of leather,
indiarubber, oilcloth or similar substance and is solidified by cooling. After
solidification, this gelatinous or glutinous substance presents an infinite number of
hollow spaces or small cavities filled with air or gas, whereby the elasticity of the
substance, which in itself is already of an elastic nature is very considerably increased,
while its weight is greatly reduced.
In order to prevent this gelatinous matter from hardening, glycerine is added in
case the same consists of glue or gelatine by which fermentation can be aided.
Further to protect the product from putrefaction, antiseptical substances may be
added such for example as formaldehyde.
This substance offers the further advantage that formaldehyde enables the mass to
resist heat.
The proportions of the ingredients which I preferably use are as follows:-
25 parts by weight of gelatine
25 parts by weight of glycerine and
1/5 (one fifth) part by weight of formaldehyde.
Instead of the product being directly pumped into the tubes hollow-cushions or the
like, it may also be east into appropriate moulds, and the cooled down and solidified
mass obtained may be subsequently provided with a suitable, tightly closing cover of
indiarubber, leather or the like.
The elasticity and the lightness of the articles thus stuffed or filled with frothy
gelatinous substance may be still further increased by means of small hollow india
rubber balls, india rubber tubes or other light and elastic bodies introduced into the
mass before the cooling of the same.
This frothy gelatinous substance produced in the manner described is especially
suitable as a filling for tyres, saddles and handle bars of velocipedes and more generally
for cushions of any kind. Such cushions are durable, will never harden and can be
produced at a comparatively small cost. A great advantage inherent in cushions of
this kind consists in their being good conductors of heat and that they will therefore
by rapidly discharging the heat, received, be kept at a low temperature when used.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An improved filling for cushions and pads of all kinds and more especially for

page_text: tyres, saddles, handles of velocipedes and the like, consisting of a spongy gelatinous
substance substantially as set forth.
2. An improved filling for cycle-tyres, saddles, cycle handles, cushions and pads
generally, consisting of a spongy gelatinous substance, in which for the purpose of
increasing the elasticity and of reducing the weight, hollow indiarubber balls, tubes
or other elastic bodies are embedded.
3. A method of producing a spongy kind of gelatinous substance, having the
characteristic feature that the gelatinous substance, obtained from glue, glue
mixtures or similar ingredients, to which glycerine and antiseptic substances are
preferably added, is liquefied by heating and is in its liquid state converted into a
froth or foam by mechanical treatment, such as beating, stirring, centrifugal action
or the like; the froth thus produced being subsequently pumped into tubes or
cushions and solidified therein, or cast into moulds and enclosed in suitable covers or
receptacles after the solidification has been completed.
4. The employment, in the above described elastic filling for cycle tyres, cycle
handles, cushions and the like of antiseptical substances such as formaldehyde for the
purpose of preventing putrefaction of the mass, the said formaldehyde also acting to
enable the mass to resist heat.
