Apparatus applicable for Levelling Coal in Coke Ovens.
We, THOMAS HUGH BELL, of Middlesbrough, in the County of York, Iron
Master, ADDISON LANGHORN STEAVENSON, of Holywell Hall, near the City of
Durham, Mining Engineer, and ROBERT CLOUGH, of Page Bank Colliery,
Willington, in the County of Durham, Engineer, do hereby declare the nature of
this invention to be as follows:-
At the present time coal is filled into coke ovens through an aperture in the roof
and it is levelled by hand labour.
To avoid or lessen the requirement for hand labour, we provide an apparatus
constructed as follows:-A cylindrical lining is inserted into the mouth of the
aperture in the top of the oven; it is open for the coal to pass down through it
and by means of arms radiating inwards it supports a vertical axis in such manner
that the same is free to revolve. The axis carries at its lower end within the coke
oven a conical frame so jointed together that it can fold together, fan like, to
admit of its being passed down into the oven through the aperture at the top, and
then expanded for use. Upon the exterior of the cone are inclined ridges or
flanges and the coal as it falls down comes against these and causes the cone with
its axis to turn round. The lower edge of the cone is fashioned obliquely so that
in some parts the coal gets free from the cone sooner than in other parts; hence
it is not conveyed so far from the entrance or centre and it falls more directly
downwards.
Thus by the form given to the cone aided by its rotation, a sufficiently
uniform distribution of the coal in the over the area beneath the cone is
obtained.

We, THOMAS HUGH BELL, of Middlesbrough, in the County of York, Iron
Master, ADDISON LANGHORN STEAVENSON, of Holywell Hall, near the City of
Durham, Mining Engineer, and ROBERT CLOUGH of Page Bank Colliery,
Willington, in the County of Durham, Engineer, 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 :-
At the present time coal is filled into coke ovens through an aperture in the roof
and it is levelled by hand labour.
To avoid or lessen the requirement for hand labour we provide an apparatus
constructed as is indicated by the drawings annexed.
Figure 1 is an elevation partly in section and Figure 2 is a plan.
A cylindrical lining a is inserted into the mouth or aperture in the top of the
ven; it is open for the coal to pass down through it and by means of arms a¹
radiating inwards it supports a vertical axis c in such manner that the same is free
to revolve. The axis carries at its lower end within the coke oven a conical
frame so jointed together that it can fold together, fan or umbrella like, to admit

The frame consists of a disc d fixed to the hollow axis c at its lower end and
wings e which are hinged at their upper ends to the periphery of the disc.
sheet iron guide or shield covering the disc d. and forming the apex of the cone.
The wings are supported in the position shown by a ring 9 against which they
rest, this ring is carried upon the lower cnd of a rod contained within the
axis c. The sectional form of the wings e is shown in Figure 3. Upon the
exterior of the cone are inclined ridges or flanges and the coal as it falls down
through the mouth in the top of the oven comes against these and causes the cone
with its axis to turn round. The axis c is suspended from a ball bearing consisting
of a part which is fixed to the axis by set screws and another part which rests
on the upper cross bars a. kk are hard steel balls introduced between, the
parts i and j. The lower edge of the cone is fashioned obliquely so that in .some
parts the coal gets free from the cone sooner than in other parts; hence it is
not conveyed so far from the entrance or centre and it falls more directly
downwards.
Thus by the form given to the cone aided by its rotation, a sufficiently uniform
distribution of the coal in the oven over the arca beneath the cone is obtained.
When it is desired to remove the apparatus from the coke oven the pin at
which supports the rod is removed and the rod is lowered until the wings e can
hang vertically downwards.
The whole apparatus may then be lifted out and conveyed away to another oven
to be again used.
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. Apparatus for levelling coal in coke ovens such that the coal thrown in at
the mouth of the oven falls upon a cone which is free to revolve and is put into
motion by the falling coal and which operates to produce a more or less uniform
distribution of the coal within the oven.
2. Apparatus substantially as herein described for levelling coal in coke
ovens..
