Improvements in Sorting or Picking Belts for Minerals and the like.
I, REGINALD HEBER SILCOCK, of King Street Wire Works, Warrington, in the
County of Lancaster, Wire Manufacturer, do hereby declare the nature of this
invention to be as follows;-
This invention relates to sorting and picking belts for the conveyance of coal,
ores and other like substances. I have found in belts in which the transverse
wires are extended and each wound round, the previous or succeeding one at each
end, and a strong edge is formed on which the belt can travel, that the life of the
belt depends practically on this edge, as it is the first to wear out, and that the
ends of the transverse wires which are bent or hooked round the previous or
succeeding one are very liable to straighten themselves, and become unfastened,
and that repeated bending them back, is liable. in course of time to break the
wires.

-
Now my invention is designed to avoid this defect, and to greatly strengthen
the construction, thereby very greatly extending the life of the belt.
The simplest plan is to mount on the transverse wires near the ends or some of
them, rotary discs so arranged that the belt travels on these discs, which thus take
the wear and tear off the belt, besides reducing friction very considerably and
the power required to drive the belt. I also couple the transverse wires together
at the ends by longitudinal links, which take a considerable part of the strain
off the wires where they are hooked, or are wound round the previous or succeeding
ones at each end, and thus the life of the belt will be very greatly extended.
My invention is not restricted to any particular kind of sorting or picking belt.
It may be applied to sorting and picking belts of almost any make. Furthermore
the links may be used without the anti-friction discs, or the anti-friction discs may
be used without the links or both may be used in conjunction whichever is pre-
ferred.

I, REGINALD HEBER SILCOCK, of King Street Wire Works, Warrington, in the
County of Lancaster, Wire Manufacturer, 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 sorting and picking belts for the conveyance of coal,

page_text: ores and other like substances. I have found in belts in which the transverse
wires are extended and each wound round the previous or succeeding one at each
end, and a strong edge is formed on which the belt can travel, that the life of the
belt depends practically on this edge, as it is the first to wear out, and that the
ends of the transverse wires which are bent or hooked round the previous or
succeeding one are very liable to straighten themselves and become unfastened,
and that repeated bending them back is liable in course of time to break the
wires.
Now my invention is designed to avoid this defect, and to greatly strengthen
the construction, thereby, very greatly extending the life of the belt.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which :-
Figure 1 is a plan, and
Figure 2 a front elevation of a belt which in a very simple manner fulfils the
object of the invention.
I mount on the transverse wires A near the ends of some or all of them, rotary
discs B, so arranged that the belt travels on these discs which thus take the wear
and tear off the belt besides reducing friction very considerably, and the power
required to drive the belt. I also couple the transverse wires A together near the
ends by longitudinal links C which take a considerable part of the strain off the
wires where they are hooked at D), or are wound round the previous or succeeding
one in each end, and thus the life of the belt will be very greatly extended.
These links are not arranged as selvedge links to protect the ends or heads of the
transverse wires, this object being secured by the use of the wire coils E described
in my prior Patent, No. 20614 of 1893, but are employed purely for the purpose
of taking off the wires, where they are hooked at D, a considerable part of the
strain.
My invention of rotary discs is not restricted to any particular kind of sorting
or picking belt, as it may be applied to sorting or picking belts of almost any
kind. Furthermore the links may be used without the antifriction discs, or the
anti-riction discs may be used without the links, or both may be used in con-
junction whichever is preferred.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The improvement in sorting or picking belts which consists in providing
them with rotary discs so arranged that the belt travels on these discs which thus
takes the wear and tear off the belt, besides reducing friction very considerably
and the power to drive the belt substantially as described.
2. In sorting or picking belts of the kind described in my prior Patent
No. 20614 of 1893 coupling the transverse wires together near the ends by
longitudinal links which take a considerable part of the strain off the wires,
these links being arranged on the inner side of the wire coils where they are
not subjected to much side wear, substantially as described.
