page_text: I, THOMAS GREAVES, of 45, Hauden Road, Lee, in the County of Kent, do
hereby declare the
this invention to be as follows:
The composition is made from a mixture of gelatine or glue, glycerine, golden
syrup and a liquid known as formalin which contains about 40% of formaldehyde
and 60% of water.
The composition may advantageously be made with the materials in the follow-
ing proportions

The gelatine or glue should be soaked in cold water from 3 to 7 hours and should
then be strained for from 12 to 24 hours.
30 units of the glycerine and the 10 of golden syrup should be then boiled
in the melting pot and the gelatine or glue added gradually until the whole is
melted, and then be allowed to boil for about half an hour, the whole being con-
tinually stirred. The remaining 20 units of glycerine should be boiled in another
pot with the unit of formalin, and when the mixture of gelatine or glue,
glycerine, and golden syrup has been boiling for half an hour, the boiling
glycerine and formalin should be added to it and the whole thoroughly stirred for
a minute or two, when the composition is ready for clothing rollers.
The advantages derived from forming a printer's roller composition in the above
way are:-
(1) That the composition is much more lasting than any other roller com-
position as yet discovered.
(2) That with this mixture I get a much tougher and more tenacious face on
the rollers that will not tear.
(3) That it is not affected by climate or changes of temperature of printing
offices, and will not swell or contract.
(4) That it can be washed with hot or cold water without detriment.

claim is:-
1. The manufacture of a composition for clothing printers' rollers substantially
in the manner hereinbefore described.
2. A composition for clothing printers' rollers composed of a mixture of gelatine
or glue, glycerine, golden syrup, and formalin.
