IMPROVEMENTS IN VARNISH OR COMPOSITION FOR COATING OINTMENT BOXES AND OTHER ARTICLES AND BODIES
Year: 1884

page_text: I WILLIAM CHARLESON of number 17 Chapel Street Bedford Leigh, in the
County of Lancaster Chemist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN VARNISH OR COMPOSITION FOR COATING OINTMENT BOXES
AND OTHER ARTICLES AND BODIES "to be as follows:-
My Invention has for its principal object to produce at a suitably low cost a
varnish or coating which will resist the solvent and penetrative actions of grease
and which will be suitable for coating the interiors of chip, turned wood and
cardboard boxes so that ointments, furniture polish, pomade and other greasy or
oleaginous matters or compositions can be kept and sold in such boxes, but
compositions prepared in accordance with my Invention can also be used for other
similar or diverse purposes as. for example for coating boxes, cases, canisters or
receptacles, bobbins used in spinning, packing paper or material and corks and for
capsuling bottles containing oleaginous, volatile, gaseous or other liquids, pickles
or other matters.
The composition is prepared from glue, resin, litharge, glycerine, chalk and water
with or without the. addition of colouring matter. China clay, pipe clay or other
suitable earthy matter may be substituted for the chalk or for some purposes may
be used in addition to the chalk to increase the substance of the composition. For
some purposes colouring matters or colours in powder are added. The glue is
soaked in the water and melted in a water bath or in a suitable apparatus and the
other ingredients or some of them are by preference ground together before being
added to the size. Fish glue is preferred.

I WILLIAM CHARLESON of number 17.Chapel Street Bedford Leigh, in the
County of Lancaster Chemist do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN. VARNISH OR COMPOSITION FOR COATING OINTMENT BOXES
AND OTHER ARTICLES AND BODIES " and in what manner the same is to be
performed to be particularly described' and ascertained in and by the following
statement:
My Invention has for its principal object to produce at a suitably low cost a
varnish or coating which will resist the solvent and penetrative action of grease
and which will be suitable for coating the interiors of chip, turned wood, and
cardboard boxes, so that ointments, furniture polish, pomade and other greasy or
oleaginous matters or compositions can be kept and sold in such boxes but
compositions prepared in accordance with my Invention can also be used for other
similar or diverse purposes as for example for coating boxes, cases, canisters or
receptacles, bobbins used in spinning, packing paper or material and corks for
capsuling bottles containing oleaginous, volatile, gaseous, or other liquids, pickles
or other matters and as a preservative from the effects of damp.
The Composition is prepared from glue, resin, litharge, glycerine, chalk and water.
with or without the addition of colouring matter.
The proportions of materials which I have found to be suitable are as follows
.namely:
Fish glue, one pound
Pale Resin, one quarter of an ounce
Litharge, one half ounce
White Chalk, one half ounce
Glycerine, one half fluid ounce
Water, forty fluid ounces.

I soak the glue in the bulk of the water for an hour or more to render it more
readily soluble when subsequently heated. The Resin, Litharge, Chalk, and
Glycerine with the addition of about half an ounce of water grind in a
suitable mill until finely reduced and intimately mixed and blended together.
I melt the glue in the water in which it has soaked by means of a water bath
preferring not to use a higher temperature than is actually needed to obtain
solution. When the solution of glue is obtained I mix all together. In all these
operations prefer to use earthenware or enamelled vessels as tin or iron vessels
are not suitable. When the preparation is to be used it is warmed sufficiently to
render it fluid and is applied by ineans of a brush to the interiors of the boxes or
receptacles or to the exteriors of the articles to be coated or the boxes or receptacles
are filled or partly filled with the preparation so that when they are emptied a
coating is left, or the boxes, receptacles or articles are dipped or soaked in the
preparation as preferred. China clay, pipe clay or other suitable earthy matter
may be substituted or for some purposes may be used in addition to the chalk to
increase the substance of the composition. The addition of other substances is
especially advisable when the composition is to be used in lieu of bottle wax
or resin to coat or capsule the corks and necks of bottles. For such purposes
I prepare a composition by adding colouring matters in powder to the aforesaid
preparation. The composition is used warm and the bottle necks are dipped into
it. If bright colours are used the composition imparts a neat and finished
appearance to the bottles or packages. Wines, spirits, ether, chloroform and other

page_text: volatile fluids may by this means be protected from excessive loss by evaporation
and the loss of gas from bottles of champagne and other aerated liquids may be
checked. The composition is well adapted to resist the attacks of the insects
which in some cases perforate the corks of liquid packages.
Colouring matter may be added to the preparation when it is to be used for any
of the other purposes for which it is adapted. I do not confine myself to the exact
proportions herein given by way of example.
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 compositions composed and prepared substantially as and for the uses
herein before set forth and indicated.
2. A composition prepared from glue, Resin, Litharge, Glycerine, Chalk or earthy
matter and water substantially as and for the purposes set forth and indicated.
3. An aqueous composition for the indicated uses containing Glue, Litharge,
Glycerine and Chalk or earthy matter or colouring matter with or without other
matters.
