Improvements in Picking Band, Elevating, and Carrying Band
Chains for Coal, Ore, or other Minerals.
JOHN QUALTER, and EDWARD HALL Engineers, Railway Foundry Midland Street,
Barnsley, Yorkshire do hereby declare the nature of this invention to be as follows:-
Picking Band, Elevating, and carrying Band Chains as at present constructed are
mostly expensive forgings or maleable castings. In these improvements we provide
a section of iron rolled expressly for the purpose and cut in lengths to forin links
revitted together with a steel or iron revit at suitable centres to pass over flat sided
drums, each link is cut semicircular at each end and on the top side of each link is
secured a steel or iron plate, revited to flange of link by ordinary steel or iron revits,
or by a specially prepared U revit and gibb to form extra bearing for Carrying
plate.
It is obvious that we may considerably vary the details of our invention without
departing from the principle thereof; For instance in using the chain as an elevating
chain we shall only use the section of L iron for every alternate link for securing
elevating buckets thereto.

JOHN QUALTER and EDWARD HALL, Engineers, Railway Foundry Midland Street,
Barnsley, 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:--
Picking Band, Elevating, and carrying band chains as at present constructed, are
mostly expensive, forgings, or malleable castings. In these improvements we provide
a section of L-iron or steel rolled expressly for the purpose, and cut in lengths to form
single & double links, which is revitted together with steel or iron revits at suitable
centres to pass over flat sided drums, each link is cut semicircular at each end, and on
the top side of each link is secured a steel or iron plate revitted to flange of link by
ordinary steel or iron revits or by a specially prepared U revit and gilb to form extra
bearing for carrying plate. It is obvious that we may considerably vary the details
of our invention without departing from the principle thereof. For instance in using
the chain, as an elevating chain we shall only use the section of L iron for every
alternate link for securing buckets thereto.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of the single and double links shewing carrying plate
revitted thereto.
Fig. 2 is a plan of the same.
Fig. 3 is an end section of thick link.
Fig. 4 is an end section of thin or double links.
A is the thick link B B is the thin links, C, C is the steel or iron plate revitted to
links with the revit D. D, E E is the steel or iron revit for revitting links together to
form chain.
Having now particulary described and ascertained the nature of our said
invention and in what manner the same is to be performed, we wish it to be
understood that we do not confine or limit ourselves to the precise details of our
improvements as herein described and illustrated on the accompanying sheet of
drawings, because numerous modifications or variations, it will be evident may be
made therein without departing from the principle or main features of our invention
and in conclusion we declare that what we claim is :-
The manufacture or construction of improved Picking Band, elevating, or carrying
band chains made from specially rolled iron or steel for the purpose as herein
described and as illustrated on the accompanying sheet of drawings.
