PROVISIONAL SPECIFICATION.
Improvements connected with Apparatus for the Manufacture of
Bleaching Powder (Chloride of Lime) or similar Commodities.
We, JAMES MORRIS MILNES, of 1 Hardshaw Street, St. Helens, Lancashire,
Chemical and Mechanical Engineer, and ALFRED MILNES, of 22 Goldhurst
Terrace, South Hampstead, London, M.A. and F.S.S. do hereby declare the nature
of this invention to be as follows:-
According to the usual appliances employed in our previously patented apparatus
for making bleaching powder (chloride of lime) the rakes for stirring and turning
the material over for impregnation by chlorine gas, a pasty substance clings or
adheres to the rakes, which causes unsaturated lumps to form requiring a certain
amount of manual labour to keep them clear, so that every particle of lime shall
have the same amount of exposure for imbibing or taking up the chlorine.
We have found in practice that by employing spear heads or conical tips as
rakes, the difficulty is overcome, and it is for the use or employment of such heads
or tips that we seek protection by Letters Patent, in combination with the other
appliances, or apparatus which constitute our previous Patent rights, and which
are numbered respectively 15833 September 18th 1891, and 19180 25th October
1892.

particularly described and ascertained in and by the following statement :-
According to the usual appliances employed in our previously patented apparatus
for making bleaching powder (chloride of lime) the rakes for stirring and turning
the material over for impregnation by chlorine gas, cause a pasty substance to
cling or adhere to them and unsaturated lumps to form which require a certain
amount of manual labour to keep the rakes clear, so that every particle of lime
sball have the same amount of exposure for absorbing or taking up the chlorine.
We have found in practice that by employing spear heads or conical tips as
rakes the difficulty is overcome when employed in combination with the other
appliances, or apparatus which constitute our previous Patent rights, and which
are numbered respectively 15833 September 18th 1891, and 19180 25th October
1892.
