PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Indexes.
HARRY NUNN, of Kidsgrove, Stoke-upon-Trent, Solicitor, and ALBERT GEORGE
Fox, of St. Catharine's College, in the University of Cambridge, Undergraduate,
do hereby declare the nature of this invention to be as follows:--
The application of a thin transparent lamina of an artificial substance of the
nature of celluloid or xylonite to the indexes (alphabetical or otherwise) of ledgers
letter files & other books or files lists or contrivances where indexes of any kind
are used. The substance to be fixed over the letter or other denoting device to
preserve the same from the effects of rough usage and consequent obliteration.
The substance can be used in any shade or in more than one shade if desired.
Coaguline being transparent is suitable for fixing the lamina. The application
of this invention to indexes would not interfere with the present system of pasting
canvass or calico on the underside of the sheet marked with the denoting device
for the purpose of strengthening. Where this invention is used the index cannot
become grimy as a damp cloth would remove any accretions neither will the index
curl up, a common thing for existing indexes to do. Double leaves may be used
and pasted together with the lamina between them, a portion having first been
cut from the upper leaf of sufficient size to expose the letter or other denoting
device employed."
