Improvements in and relating to a Composition for Use when
Making Moulded Articles.
I, GEORGE RAPER, of 219, Mare Street, Hackney, in the County of Middlesex,
Boot Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a novel method of combining & forming into a hard
& solid composition such materials as:-Cotton waste, leather waste, paper scrap,
wood dust, wool scrap, & the like, with a liquid compound of:-albumin, alum,
caseine, copperas, flour, glue, gluten, and water, and is carried out as follows:-
I first dissolve, by boiling, the albumin, alum, caseine, copperas, flour, glue,
gluten, and water, thus forming a liquid.
I then proceed to add one or more of the aforesaid materials such as, cotton
waste, leather scrap, paper scrap, wood dust, wool scrap, and the like.
I then work the whole into a stiff paste or composition and proceed by any
well known and suitable means, to mould the said composition into any desired
shape. The said moulded articles are next dried, by any well-known and suit-
able means, until hard.
I also claim to vary the aforesaid method of proceedure by boiling a part only
of the liquid aforesaid and using a part raw or unboiled.

Improvements in and relating to a Composition for Use when
Making Moulded Articles.
I, GEORGE RAPER, of 219, Mare Street, Hackney, in the County of Middlesex,
Boot Manufacturer, 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 improvements in and relating to a composition for use
when making moulded articles and consists in the combination of certain
materials, such as cotton waste, leather dust, paper pulp, wood dust, wool scrap,
and the like with a liquid compound of albumen, alum, caseine, copperas, flour,
glue, gluten and water to form a hard and solid composition.
In carrying out the invention the albumen, alum, caseine, copperas, flour,
glue, gluten and water are first dissolved by boiling so as to form a liquid. One

stiff paste which can be moulded to any desired shape by any well known suit-
able means. The moulded articles are afterwards dried until they are hard.
I have found in practice that good results are obtained when the liquid and
solid compositions are formed with the materials in the following proportion,
that is to say:-
For the liquid
About

"
-19
pint of a saturated solution of alum.
ounce of copperas.
2 pounds of glue.
4 quarts of milk (albumen, caseine) and water as required.
For the solid-
2 pounds of flour and
4 ounces of dextrine (gluten) and one or more of the above mentioned waste
materials.
The quantity and nature of the waste material used will be varied to suit the
article it is 'desired to manufacture; for example, where I desire to manufacturo
boot heels I advantageously employ a quantity of leather dust and where I desire
to manufacture a substitute for wood handles, for instance, I may use dust of a
hard wood such as mahogany.
Instead of boiling the whole of the constituents forming the liquid I may
employ a portion thereof in the raw or unboiled state.
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
1. The described process for the manufacture of a composition for making
moulded articles, such process consisting in combining and working into a stiff
paste which can be moulded a liquid composed of albumen, alum, caseine,
copperas, flour, glue, gluten and water and a solid formed of one or more materials
such as cotton waste, leather dust, paper pulp, wood dust, wool scrap and the like,
substantially as hereinbefore described.
2. A composition for making moulded articles, such composition being manu-
factured from the ingredients in the manner and substantially in the proportions
herein before described.
3. Moulded articles manufactured substantially as hereinbefore described.
