PROVISIONAL SPECIFICATION.
'An Improvement in the Manufacture of Black-lead Blocks.
We WILLIAM BURTON LAWSON of Penny Street Lancaster, Draper and
HOULDSWORTH SCHOFIELD of 56 Bishop Street Moss Side Manchester Com-
mercial Traveller, both in the County of Lancaster do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improvement in the manufacture of black-lead
blocks such as are used for polishing stoves and for other similar polishing purposes,
the object of the invention being to obtain a much blacker and more brilliant
looking polish than can be obtained by the use of the ordinary black-lead blocks
as hitherto manufactured.
For this purpose we manufacture our improved blocks in the following manner.
We take about equal quantities in bulk (not weight) of powdered black lead
and of the best lamp vegetable black, and mix and grind them together into a fine
powder.
We then add thereto sufficient water or other suitable liquid to bind or agglomerate
the powder together, and then press the same into blocks of a convenient and
suitable size and form for use.
The combination of the vegetable black with the black-lead will not only greatly
improve the color and appearance of the polish but will also economize the cost
of manufacture.
