The Preparation of Ingredients for the Manufacture of Ornamental
and other Tablets.
I ALFRED JOHN PARKER of 20 Walpole Street, New Cross, Surrey, Machine
Printer, do hereby declare the nature of my 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 has for object the preparation of certain ingredients in a special
manner and the employment of the compound made therefrom for the manufacture
of tablets, panels or like articles, for internal or external decoration, but particularly
adapted for advertizing and like purposes.
According to my invention I first soak and melt 4 lbs. best glue in 4 lbs. water
and leave it to simmer until all the water has evaporated. To this glue I add 2 lbs.
crystallized sugar which dissolves by agitation and I pour this combination into a pan
containing 4 lbs. melted resin, the heat of which is somewhat low.
I bake 4 lbs. plaster of Paris and then grind it to a powder sifting the flour there-
from with which I mix 2 lbs. glycerine by a grinding operation and make a paste.
This paste I stir gradually into the combination of ingredients before mentioned until
thoroughly amalgamated, and constitutes the compound which can be moulded.
The compound when required for use is heated and spread upon a polished surface
or bed in or on which the pattern or device is made the compound being squeezed
or rolled to press out any air bubbles that may have been formed, I then lay a sheet
of zinc or other metal, previously sized, on to the composition which will adhere
thereto. The thickness of the composition may be determined by side walls or fillets
around the bed.
When the compound is sufficiently set the bed is turned over and the composition
affixed to the zinc plate will leave it.
The composition made with the ingredients before described would be of a dark
brown colour and any suitable colouring matter can be mixed with the compound
when in a heated state, or where pattern in colour has to be produced parts of the
bed plate may first have colour placed upon it (where desired) which will be absorbed
by the compound when spread upon it.
The compound in its uncoloured state, when set, can be painted, gilded, varnished,
or otherwise coated for bringing out the outline of the device according to taste or
fancy.
The zinc plate forins a backing to the composition and enables it to he suspended in
the ordinary way of tablets or affixed to an article.
The proportions of the several ingredients for the purpose of my invention are
subject to slight variations according to the density of the required composition and
the purpose for which it is intended.
I prefer to use zinc as the backing to my composition because it can easily be
bent to conform to surfaces other than Hat without interfering with, or destroying the
device upon or in the surface of the composition.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
1. The preparation of the ingredients named in the manner and for the purposes
described.
