Sealed the 10th May 1878, and dated the 12th March 1878.
PROVISIONAL SPECIFICATION left by the said Thomas Hugh Bell, William

the 12th March 1878.
THOMAS HUGH BELL, of Middlesbro', in the County of York, and WILLIAM
HARLE and ROBERT CLOUGH, both of South Brancepeth Colliery, in the County of
Durham. "IMPROVEMENTS IN APPARATUS FOR CONVEYING COKE FROM THE COKE
OVENS, AND LOADING IT INTO TRUCKS."
This Invention has for its object improvements in apparatus for conveying coke
from the coke ovens, and loading it into trucks. In front of the range of coke
ovens and about on a level with the bottom of the door openings, we arrange an
endless belt consisting of iron plates attached to chains passing over rollers at either
end.
As the coke is drawn out of the ovens by means of rakes in the usual way it fulls
on to this endless belt (in place of on to the ground as heretofore), and it is auto-
matically carried away.
As the belt passes over the roller at one extremity of the course the coke falls
into a shoot which delivers it on to another similar belt set at an inclination, such
that it may carry the coke up to the top of the screen.
The large coke slides down the face of the screen and falls into a railway truck
which stands beneath to receive it, or into a hopper or other receptacle, from which
it may subsequently be loaded into a railway truck or a barrow, whilst the small

page_text: coke or breeze passes through the screen and is received into another truck. The
trucks stand upon parallel lines of rails.
For a long range of coke ovens we arrange two endless belts in front of the
ovens, both delivering the coke from opposite directions to the same transverse
elevating belt.
In order that the coke may not slip back along the face of the elevating belt we
provide ledges or ridges, upon the transverse plates of which the face of this belt is
composed. In this way without any manual labour being expended the coke is
conveyed direct from the mouth of the oven into the railway truck, and much of
the breakage involved in handling is avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Hugh Bell, William Harle, and Robert Clough in the Great
Seal Patent Office on the 11th September 1878.

OVENS, AND LOADING IT INTO TRUCKS."
This Invention has for its object improvements in apparatus for conveying coke
from the coke ovens, and loading it into trucks. In front of the range of coke
ovens and about on a level with the bottom of the door openings, we arrange an
endless belt consisting it may be of iron plates attached to chains passing over
rollers at either end, or otherwise conveniently constructed.
As the coke is drawn out of the ovens by means of rakes in the usual way it falls
on to this endless belt (in place of on to the ground as heretofore), and it is auto-
matically carried away.
As the belt passes over the roller at one extremity of the course, the coke falls
into a shoot which delivers it on to another similar belt set at an inclination, such
that it may carry the coke up to the top of a screen, or it may deliver it at once
into a wagon or truck.
Whero a screen is employed the large coke slides down the face of the screen and
falls into a railway truck which stands beneath to receive it, or into a hopper or
other receptacle, from which it may subsequently be loaded into a railway truck or
a barrow, whilst the small coke or breeze passes through the screen, and is received
into another truck, or is otherwise disposed of. These trucks stand upon parallel
lines of rails.
For a long range of coke ovens we arrange two endless belts in front of the ovens,
both delivering the coke from opposite directions to the same transverse elevating
belt.
In order that the coke may not slip back along the face of the elevating belt, we
prefer to provide ledges or ridges, upon the transverse plates of which the face of

page_text: this belt is composed. In this way without any manual labour being expended the
coke is conveyed direct from the mouth of the oven into the railway track, and
much of the breakage involved in handling is avoided.
In order that our said Invention may be most fully understood and readily
carried into effect, we will proceed to describe the Drawings hereunto annexed.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation, and Figure 2 is a plan of a range of coke ovens
having apparatus for conveying away the coke combined with them in accordance
with our Invention; Figure 3 is a section taken on the line A, B, in Figures 1
and 2.
a, a, a, are the coke ovens; and a¹, a¹, a¹, are the doors or openings from which
the coke is extracted by the workmen; b, b, are endless travelling belts running
along the fronts of the ovens, their upper surfaces being about on a level with the
bottoms of the doors or openings. These belts pass around rollers at their ends,
and one roller for each belt receives motion from a driving shaft c, which by gear
wheels, pulleys, and driving bands, as the Drawings indicate, gives a slow movement
to the belts.
The workman when drawing the coke out of the oven in place of throwing it out
on to the ground as at present, draws it out of the oven on to the belt b, and this
belt carries it slowly along until it reaches the elevating belt d; the belts b in
passing around the rollers at their ends in proximity to the elevating belt deliver
the coke on to this belt, which is similar to the belts b, except that the plates upon
it are provided with ledges or ridges to prevent the coke slipping back, which it
might otherwise do in consequence of the inclined position of the belt.
The upper roller of the belt d receives motion from the driving shaft c by means
of shafting and gear, the nature of which is clearly indicated in the Drawings.
The coke falling off from the belt d at its upper end descends over the surface of
the screen e, and the small or breeze passing through the screen is received into the
truck f, whilst the large coke passes into the trough-like feceiver g.
The receiver g retains the coke until there is a sufficient quantity accumulated to
raise the counterpoise weights h, h, and then the receiver by moving around its axis
g delivers the coke into the truck i beneath.
By the application of the receiver g (which however forms no part of our In-
vention) the coke is less broken than it would be were it allowed to fall direct
from the screen into the truck i.
Having thus described the nature of our said Invention and the manner of per-
forming the same, we would have it understood that we claim,-
First. The combination with coke ovens of travelling belts suitably arranged to
receive the coke as it is drawn from the ovens, and convey it away automatically
into trucks or receivers, substantially as described.
Second. The arrangement of apparatus for conveying coke from coke ovens, sub-
stantially as berein described, and represented in the annexed Drawings.
In witness whereof, we, the said Thomas Hugh Bell, William Harle, and
Robert Clough, have hereunto set our hands and seals, this Twenty-second
day of August, in the year of our Lord One thousand eight hundred and
seventy-eight
