Improvements in and relating to Conveying Belts for Minerals
and the like.
We, NATHANIEL GREENING and N. GREENING AND SONS LIMITED of Crown
Street Warrington in the County of Lancaster, Wire Manufacturers, 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 belts or bands for conveying minerals and the like and
more particularly to the links of which such belts are constructed, its objects being
to increase their strength and durability and to simplify their construction.
Each link consists essentially of two side plates joined together at their ends by
two tubes. The side plates are slotted or otherwise perforated for the reception of
blinding bars. A belt or band is built up by placing the links together in such a
manner that the ends of the links in one row across the belt come between and
alternate with the ends of the links in the adjacent row, the two rows being secured
together by a bolt or pin passing through the tubes which join together the side
plates of each link. Different kinds of blinding bars may be employed with the
links or with the belt; in one form a lath or straight bar extends from side to side
of the band passing through the slots in the side plates of the links, while in another
form each link and each of the spaces between links in each row across the belt
may be provided with a separate bar section. In the first form the movement of
the bar across the belt and its accidental removal are prevented by bolting solid
plates along the edge of the band, some of the plates if desired being arched or
otherwise provided with a projection which extends laterally to a greater extent
than the ends or heads of the bolts or pins which connect the links and thus
protect them from wear, as described in the Specification of Letters Patent
No. 10728 of 1893.
In some bands it is desirable to form the edges with flanges or the like to keep
the conveyed material in its proper position on the belt. We may achieve this by
bolting larger plates to the edges of the belt or by forming some of the links with
one side plate larger than the other and using these links for the edges.
In order that our invention may be more readily understood we have hereto
appeuded drawings to which we refer hereinafter. Similar letters of reference
are used to indicate similar parts where they occur in the different figures.
Figure 1 illustrates in plan part of a belt constructed according to .this
invention.
Figure 2 shows in plan and side elevation one of the improved links.
Figure 3 illustrates in plan one of the links fitted with a separate blinding. bar
section.
Figure 4 is a representation of a few such links fitted together to form part of
a belt.
Figure 5 represents two different blinding bar sections employed.
Figure 6 shews in end elevation and in side elevation one of the links formed
with a flange and adapted for use at the edge of the belt.
Figure 7 is an edge view of part of a belt fitted with large plates to form
a flange.
The links each consist of two side plates A and A' joined together at their ends
by the tubes B and B which are riveted or otherwise securely held in place.
Each of the side plates is slotted or perforated as at C. In the formation of a belt

page_text: or band the links are placed together in such a manner that the ends of the links
in one row fit between and alternate with the ends of the links in the next row as
is plainly shewn in Figure 1. Bolts, pins, or the like D, are then passed through
the tubes B and B and hold the links firmly together while at the same time
permitting limited independent movement. In the method of blinding adopted in
the belt shewn in Figure 1 a lath or bar E is passed through the slots C in cach
row of links from side to side of the belt and is prevented from being withdrawn
by a plate For F1 secured to the edge of the belt. Additional plates G are used
to support the ends of the bars which come into spaces between links. Some, and
preferably alternate ones, of the side plates may be arched or otherwise suitably
formed to project further than the ends of the bolts or pins D and thus protect
them from wear, as already herein before described.
With the blinding bars and the method of blinding illustrated in from Figures 3
to 5, each link and each space between links is provided with a separate plate E
these plates being of two different sizes as shewn in Figure 5, and each forming a
section of a blinding bar. They are arranged to completely blind all spaces in the
belt and are formed with reduced ends e which overlap each other within the
slots C of the side plates of the links. The two sizes of plate are of course necessary
as there is a greater space between links than there is contained within the links.
The bars or plates contained within the links are placed there during construction
before the two side plates of each link are finally secured together; the plates
contained in the spaces between the links are placed in position as the belt is built
up from the links. When the plates at the edges of the belt are contained between
links additional plates may be employed to support and retain them as previously
described and as illustrated at G Figure 1 with reference to the ends of the blinding
bars there shewn.
The link represented in Figure 6 is intended for use at the edge of a belt and is
formed with one side plate A of an increased height so that a series of them form
a flange along the belt edge. The plates extending across the spaces between the
edge links may be similarly increased in height. As an alternative instead of
increasing the side plates of the links, the edge plates F F Figure 1 may all be
enlarged to form a flange as illustrated by Figure 6.
Belts constructed as hereinbefore described may be driven or operated by being
passed around polygonal drums the flat edges of the links abutting against the
plane surfaces, or the transverse fastening bolts may be extended beyond the edges
of the belt to engage with toothed wheels, or any other suitable or known method
of driving may be adopted.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In conveying belts, links constructed of slotted side plates, and end connecting
tubes, substantially as herein before described and as illustrated by the accompanying
drawings.
2. In conveying belts, blinding bars constructed in sections and adapted to be
fitted in and between the links, substantially as herein before described and as
illustrated by the accompanying drawings.
3. In conveying belts, side links each having its outer edge deeper than the
inner edge, substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
4. Conveying belts constructed substantially as herein before described and a
illustrated by the accompanying drawings.
