PROVISIONAL SPECIFICATION.
An Improvement in Coal Screening and Breaking Apparatus.
I, HENRY SIMON of No. 20 Mount Street Manchester in the County of Lancaster
Civil Engineer do hereby declare the nature of this invention to be as follows :-
This invention relates to an arrangement of apparatus employed for the screening
and breaking preparatory to coal washing in such a manner as to economise time
and labour.
Trucks conveying the crude coal are run on to a tipping stage, and, being there
tipped, deliver their contents upon a slightly sloping oscillating screen. The smaller
fragments fall through the meshes of the screen into the washing pit, the larger pieces
are delivered over the lower end of the screen on to a shoot whence they pass to a
stone breaker. From the stone breaker the crushed coal drops into the washing pit
and from the washing pit the washed coal is raised by an elevator to be farther dealt
with if necessary or to be delivered into trucks for transport.
Dated this 15th day of February 1889.

COMPLETE SPECIFICATION.
An Improvement in Coal Screening and Breaking Apparatus.
I, HENRY SIMON, of No. 20 Mount Street, Manchester, in the County of Lancaster,
Civil Engineer, 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 an arrangement of apparatus employed for the screening
and breaking preparatory to coal washing in such a manner as to economise time and
labour, as I shall describe referring to the accompanying drawing which is a
vertical section shewing the arrangement of the apparatus according to the present
invention.
Trucks T conveying the crude coal are run on to a tipping stage G, and, being
there tipped, deliver their contents upon an inclined oscillating screen M. The
smaller fragments fall through the meshes of the screen into a pit P, the larger
pieces are delivered over the lower end of the screen and an inclined shoot N to a
stone breaker S by which they are crushed. From the stone breaker the crushed
coal is delivered into the pit P, or is conveyed upwards by an elevator and dropped
into the pit. From this pit the crushed coals along with the smaller fragments that
had passed through the screen are raised by an elevation F and are delivered to
washing apparatus which may be arranged and operated as described in the
Specification No. 6341 of 1888.
The apparatus which I have above described is intended chiefly to deal with
dirty intergrown lump coal, which often under ordinary circumstances is thrown
away as waste. This intergrown coal is usually accumulated near the screens,
inconveniently occupying space. I dispose of it by loading it into the trucks T
along with the coal that has to be washed, and by the screening and crushing
as above described, I bring it to a condition such that when it is washed along
with the other coal the carbonaceous portions which are available as fuel are
saved.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of a tipping platform, an oscillating screen and shoot and a stone
breaker, substantially as and for the purpose set forth.
Dated this 15th day of November 1889.
