Improvements in Lime Cartridges for Breaking-down Coal, Rock,
and other Minerals.
I MILES SETTLE of Darcy Lever in the County of Lancaster, Colliery
Proprietor, do hereby declare the nature of this 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 relates to improvements upon the subject matter of an application
for Letters Patent No. 23268 dated December 4th 1893 the Complete Specification
of which has been duly filed.
The nature and object of the present improvements and the manner in which the
same is to be performed or carried into practical effect will be readily understood
on reference to the annexed sheet of drawings and the following explanation
thereof.
Fig. 1 is a transverse section and Fig. 2 a longitudinal section of my improved
lime cartridge in its simplest form.
Fig. 3 is an end view and Fig. 4 a partial sectional elevation of a modification
thereof hereinafter more particularly described.
With reference to Figs. 1 and 2, in addition to making the compressed lime
cylinder a with a central hole 6 as described in the Complete Specification above
referred to, I provide the same with longitudinal passages or flattened spaces d
radiating outwards from the central hole 6 and extending from end to end of the
cylinder a or nearly so. The object of these additional radiating spaces is to
facilitate the rapid distribution of the water or acidulated water to the whole mass
of the lime when it is forced into the central hole 6 by the pump.
In the modification shown at Figs. 3 and 4, in addition to the central hole b I
make several auxiliary holes b' surrounding the central hole, and I connect them
therewith by longitudinal flattened spaces d radiating from the central hole 6 to the
auxiliary holes 61, and at the ends of the cartridge I make shallow channels e
connecting the holes b and 62 together, and with the longitudinal channels or
grooves c outside the cylinder a.
By these two methods the water or acidulated water is more evenly distributed,
as regards Figs. 1 and 2, longitudinally through the centre of the cartridge and
radially into the interior of the mass; and as regards Figs. 3 and 4, it is distributed
first centrally into the hole b then radially along the passages d to the auxiliary
holes and thence at the ends along the shallow connecting channels e to the
longitudinal grooves c outside the cylinder, so that the water or acidulated water
acts simultaneously on a great surface of the lime cylinder, the effect of this being
to hasten the operation of breaking-down the coal or other mineral.
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 I
claim is :-
The improvements in lime cartridges hereinbefore described and illustrated by
the drawings annexed and more particularly I claim the use of the internal radiating
passages d in combination with the central hole b, either with or without the

page_text: auxiliary holes 6¹, and either with or without the external shallow channels e and
longitudinal grooves c, substantially as hereinbefore described and illustrated by
the annexed drawings.
Dated this 23rd day of August 1894.
