Improved Belting for Conveying and Cleaning Coal and other
Goods.
I, WILLIAM EDWARD KOCHS, Engineer and Machinery Agent, of No. 11,
The Parade, Tredegarville Cardiff, in the Principality of Wales, England do
hereby declare the nature of this invention to be as follows:-
The purpose of this invention is to introduce improved steel or iron link and
plate beltings for the conveying of coal or other goods and articles to a distance,
or of spreading them over their travelling surface for examination or cleaning,
the belting having in their peculiar construction the distinguishing feature of
preventing coals or other goods from falling through, that is, between the plates
or elsewhere, and also of combining great strength, (which permits of heavy
weights being placed on them, and of the pick being used for cleaning stones from
lump coal) with lightness and simplicity. construct the belting plates which have
hitherto been made with flat surfaces, convex, with the round side up, the
curvature being made to the outer circular line of the end drums, or the so called,
revolving, toothed propeller sheaves, the plates laying over the outer edges of the
rounded off link ends. The width of each plate is exactly equal to the length of
the links, measured from centre to centre of the bolts or the link pins, which join
them, the plates being rivetted to the flanges of the links. The length of the
links is equal to the side of an hexagonal or other regular figure, into which the
circumference of the propelling sheave is divided. The edges of these plates are
planed to the correct width and it will be seen, that these, in their horizontal
course or position, butt closely against each other and that they unitedly carry
the weights upon them, the neighbouring plates assisting in supporting the load
resting on the one between them. The plates form tight joints, the closeness of
which is increased by the weight placed on them. The outer ends of each belt
plate have upright or outwardly inclined plates rivetted to them, either by means
of angle bars curved to the belt plates, or by the plates themselves being bent to
fit under them. These upright or inclined plates are again of the same width as
the curved plates, that is, equal to the length of the links, and in their horizontal
course or position they fit close against the edges of their neighbouring plates,
thus forming a close boundary, by which coal or other articles are prevented from
falling off or between them. Upon a plate changing its horizontal course, or
position when it approaches the propeller sheave, its edge nearest the sheave
descends gradually and departs from the neighbouring edges of the other plates,
leaving openings all the way between them. These openings are however held
closed by narrow plates which are rivetted longitudinally one under the edge of the
preceeding plate, and the portion of this narrow plate, which is free, is curved to
suit the outer curvature of the link end over which it lays, so that the edge of the
succeeding plate follows the top curve of the closing plate, keeping the opening
tightly closed during the whole time when it revolves round the. propelling
tumblers, until it again enters the straight course, when the plates again butt close.
All the links have flanges, by which they are fixed to the plates, and are by
preference, made of cast steel or of suitable cast iron. The double links receive
the tooth of the revolving propeller between them and the single links are the
bearers, each of one or two pairs of travelling rollers or sheaves, the spindles of
which finding supports in the middle of such links. These sheaves or rollers

page_text: travel on suitable rails and angle irons, which are fixed on transverse bearers or
direct on the framework.

Improved Belting for Conveying and Cleaning Coal and other
Goods.
I, WILLIAM EDWARD KOCHS, Engineer and Machinery Agent of No. 11
The Parade, Tredegarville, Cardiff, in the Principality of Wales, England, 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:-
The purpose of this invention is to introduce improved steel or iron link and
plate beltings for the conveying of coal or other goods and articles to a distance,
or of spreading them over their travelling surface for examination or cleaning, the
belting having in their peculiar construction the distinguishing feature of
preventing coals or other goods from falling through, that is, between the plates or
elsewhere and also of combining great strength, which permits of heavy weights
being placed on them, and of the pick being used for cleaning stones from lump
coal, with lightness and simplicity. I construct the belt plates, which have
hitherto been made with flat surfaces, convex, with the round side up, the
curvature being made to the outer circular line of the end drums, or the revolving,
so called toothed propeller sheaves, the plates laying over the outer edges of the
rounded off link ends. The width of each plate is exactly equal to the length of
the links, measured from centre to centre of the bolts or the link pins, which join
them, the plates being rivetted to the flanges of the links. The length of the
links is equal to the side of an hexagonal or other regular figure into which the
circumference of the propelling sheave is divided. The edges of these plates are
planed or made to the correct width and in their horizontal position butt closely
against each other, thus assisting each other in carrying the load resting over them
and forming at the same time tight joints. The outer ends of each belt-plate have
upright or outwardly inclined plates rivetted to them, either by means of angle
bars curved to the belt plates or by the plates themselves being bent to fit under
them. These upright or inclined plates are again of the same length equal to the
width of the curved belt plates, that is equal to the length of the links, and in
their horizontal course or position they fit close against the ends of their neigh-
bouring plates, thus forming a close boundary, by which coal or other articles are
prevented from falling off, or between them. Upon a plate changing its horizontal
course or position when it approaches the propeller sheave, its edge nearest the
sheave descends gradually and departs from the neighbouring edge of the
preceeding plate, leaving an opening all the way between them. This opening is
however held closed by a narrow plate which is rivetted longitudinally under the
edge of the preceeding plate and the portion of this narrow plate, which is free, is
curved to suit the outer curvature of the link end over which it lays, so that the
...edge of the succeeding plate follows the top curve of the closing plate, keeping
the opening tightly closed during the whole time when it revolves round the
propelling tumblers, until it again enters the straight course, when the plates again
butt close. All the links have flanges, by which they are fixed to the plates and
are by preference made of cast steel or of suitable cast iron. The double links
receive the tooth of the revolving propeller between them and the single links are
the bearers of travelling rollers or wheels, the spindles of which finding their

page_text: support in or about the middle of such links. These wheels travel on suitable
rails and angle irons, which are fixed on transverse bearers or direct to the frame
work.
With reference to the by following plan Figs. 1, 2, 3, 4 a, a a are the belt plates,
curved to the circular line described by their position on the links passing over the
end propellors. ce are the flanges of the links to which the plates are fixed or
rivetted. d, d are the joint protecting plates, either rivetted under one edge of
the curved plate as shewn in Fig. 1 or at once rolled on the plate as shewn in
Fig. 4. These joint protecting plates are curved to the outer circle of the link
ends. ff are the travelling wheels by preference under every 3rd link or plate
and g the guide rails, 7 is the angle iron fixed to the lower part of the frame. i is
the toothed propelling wheel with by preference 3 teeth KKK. I are the flanges
on which the links place themselves; m. m are the angle irons rivetted to the ends
of the curved belt plates and n the shoot which is fitted close to the cylindrical
curves of the plates on the propeller sheave, the upper edge of which being slanted,
so as not to meet the parallel edges of the plates. This plate receives the coal or
other goods from the belt and prevents their falling.
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. Constructing the belting substantially as described in the foregoing
Specification, that is to say, making the belt plates convex, curved to the exact
circle or cylinder formed, when they lay over the propelling wheels or drums at
the ends of the belt.
2. Making the curved belt plates to butt against each other and rivetting
under one edge of them, or rolling, in making the plates, joint protecting plates on
them, curved to lay exactly over the outer curve of the link ends.
3. Placing the sharp edge of the shoot plate against the outer circle of the
revolving cylindrical plates, thus taking the coal or other goods off the belt
surface without their falling.
4. Placing the travelling wheels under, or near the middle of the belt plates
and closing the sides of the belting by fixing angle irons or plates at the ends of
the belt plates butting close against each other.
