Improvements in Apparatus for Delivering Coal or other Materials
into Trucks or other Receptacles.
I, CUTHBERT BURNETT, of Fallowfield, South Hetton, in the County of Durham,
Engineer, do hereby declare the nature of this invention to be as follows:-
These improvements in apparatus for delivering coal or other materials into
trucks or other receptacles are of special value in connection with delivery from
belts for cleaning coal or other minerals, and therefore the nature of the present
invention will be described in connection with such a cleaning belt.
Heretofore in such cleaning belts as have been made with a movable jib end
as described in the Patent Specification No. 18763 of 1891, the upper side of the
said belt carried the coal down to the truck and discharged it into it over the
jib end so that the coal had to fall from a height at least equal to the belt
drum at the jib end. Now according to this present invention and in order to
minimise the breakage of coal, I construct a jib end with an endless belt or a
chain having equidistant upstanding plates boards tines or fingers and combine
the said jib end with an open shoot or gutter underneath it which shoot at its
bottom end can be placed in the bottom of the truck to be loaded while its other
or upper end forms a continuation of the upper side of the cleaning belt. This
jib end is capable of being raised at its lower end by a winch or other suitable
means. In one form of the apparatus the jib end is at its upper end jointed to
a short link frame that can turn on the drum spindle of the cleaning belt. The
cleaning belt may be constructed of canvas, wire, or made of curved plates all of
which would present a rounded and true.surface on the drum.
The effect of the above arrangement is that the coal passes from the end of
the upper side of the cleaning belt, on to the shoot, and is, by the boards on the
lower part of the jib end belt, conveyed down the shoot when the latter with the
jib end is placed at the required inclination. The coal will thus practically have
only a few inches of fall.
In belts with flat trays and polygonal pulleys as ordinarily constructed in order
to secure the advantage afforded by belts of the before mentioned class described.
the said belts are made as follows:-The cleaning belt having been continued for
the greater part of its length in a straight. direction is at its delivery end made
with a slanting dip and upon this slanting part rests the upper end of the aforesaid
shoot of the jib end belt some distance above or clear of the polygonal drum at
this end of the cleaning belt so that the coal can with ease pass from the cleaning
belt on to the shoot and be conveyed down the latter by the boards on the lower
side of the jib belt.

I, CUTHBERT BURNETT, formerly of Fallowfield, South Hetton, in the County of
Durham, but now of The Grange, near 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:-
These improvements in apparatus for delivering coal or other materials into
trucks or other receptacles are of special value in connection with belts
for cleaning coal or other minerals, and therefore the nature of the present
invention will be described in connection with such a cleaning belt.
Heretofore in such cleaning belts as have been made with a movable jib end
as described in the Patent Specification No. 18763 of 1891, the upper end of the
said belt carried the coal down towards the truck and discharged it over the jib end
so that the coal had to fall from a height at least equal to the diameter of the belt
drum at the jib end. Now according to this present invention and in order to
minimise the breakage of coal I construct a jib end, with an endless belt or
chain having equidistant upstanding plates, boards, tines or fingers, and I combine
the said jib end with an open shoot or gutter underneath it which shoot at its
bottom end can be placed in the bottom of the truck to be loaded, while its other
or upper end forms a continuation of the upper side of the cleaning belt.
jib end is capable of being raised at its lower end by a winch or other suitable
The effect of the above arrangement is that the coal passes from the
end of the upper side of the cleaning belt on to the shoot, and is by the boards
on the lower part of the jib end belt conveyed down the shoot when the latter with
the jib end is placed at the required inclination. The coal will thus practically
have only a few inches of fall.
means.
This
Fig. 1 of the drawings illustrates one form of the apparatus being a sectional
side view in which the jib end is constructed with an endless belt or chain A
having equidistant upstanding plates, boards tines or fingers A' and passing
around cylindrical drums A2 A2; underneath this jib end and hung on its upper
drum spindle G is arranged a shoot B the bottom end of which is placed in the
bottom of the truck C that is to be loaded while its upper end forms a continuation
of the upper side of the cleaning belt "D. This jib end is capable of being raised
at its lower end by chains or cords K¹ from a winch or other suitable means.
The upper end of the jib is jointed to short arms or a link frame E that turns on
the drum spindle F of the cleaning belt D).
The effect of the above arrangement is that the coal passes from the end of
the upper side of the cleaning belt D on to the shoot B, and is by the boards A¹
on the lower part of the jib end belt A conveyed down the shoot when the latter
with the jib end is placed at the required inclination. The coal will thus
practically have a few inches of fall.
The cleaning belt may be constructed of canvas or woven wire or made of
curved plates turned up at the ends and united by clips which enter recessed parts
formed at equal intervals in the belt pulleys as is well known. The curved
plates then have angle flanges which pass over supporting pulleys at the bottom
and supporting pulleys at the top.
Fig. 2, in two parts Sheets 2 and 3, is a side elevation showing the invention
applied to a jib end with endless belt or chain passing over polygonal drums and
Fig. 3 is an end view of the raising and lowering gear. The cleaning belt D is
here intended to be of canvas or woven wire or other suitable material for passing
around a circular drum D¹ against which comes the upper end of the shoot B

page_text: that receives the coal from the cleaning belt D.
On
The upper end of the jib is
jointed to a short link frame or arms E that can turn on the drum spindle F of
the cleaning belt D. The jib end in this case is made in the form of an endless
link belt A passing round polygonal drums A3 A3 and provided with arms or
boards A which are by preference hinged to the link belt A as shown in dotted
lines as regards the first arm A¹ so that any coal rushing down may not strike
a rigid but a yielding surface and breakage of the coal be thus prevented.
the upper shaft G of the jib end are provided two rollers H one at each end
which are adapted to roll on radial tracks I for the purpose of supporting and
steadying the shoot B.
At the other end of the jib end and shoot at a suitable
distance above the same is placed a raising and lowering apparatus of any suitable
form but here, as an example, shewn as consisting of two wheels or pulleys K
over which passes the rope K with counterweight K². The worm wheel L on
the pulley shaft is in gear with a worm M the shaft of which carries a bevel
wheel N which can be brought into gear with the bevel wheel O or the bevel
wheel O¹ that are loose on their shaft all according as the clutch P is shifted
along a feather on its shaft to one side or the other by means of the clutch
lever P and thus raising or lowering as the case may be the jib end as required.
In cleaning belts with flat trays and polygonal pulleys in order to secure the
advantage afforded by belts with round pulleys, as hereinbefore described or by
a belt constructed with curved plates. I make the belt as follows. The cleaning
belt D having been continued for the greater part of its length in a straight
direction is at its delivery end made with a slanting dip and upon this slanting
part rests the upper end of the aforesaid shoot B of the jib end belt A some
distance above or clear of the polygonal drum at this end of the cleaning belt so
that the coal can with ease pass from the cleaning belt on to the shoot and be
conveyed down the latter by the boards on the lower side of the jib belt.
The
Fig. 4 shews such an arrangement. In this case the plates of the cleaning
belt D are joggled underneath so that the trays are level on the surface upon
which the coal lies, and the belt is constructed with a dip at the delivery end the
angle of the dip being preferably a little greater than the angle of repose for
the coal, so that the latter will fall gently therefrom. Between the two poly-
gonal drums D1 and D2 I may provide two round supporting rollers Q Q and
at a suitable point between them I fix a plate R R¹ to receive the coal.
lower part R of this plate is hinged to the upper part R for the purpose of
yielding with the bottom of the shoot B while the latter is being raised or
lowered. The shoot B with jib end is in this case also provided with arms or a
frame E that is supported on the shaft F of the cleaning belt. The jib end is
adapted to be raised and lowered as in the previously described arrangements.
The arms or boards A¹ on the jib end are also in this case by preference hinged
for the purpose stated.
Fig. 5 shews partly in section another arrangement of cleaning belt with
polygonal drums or rollers, said belt having a dip at the delivery end. This
is especially applicable where a simple shoot is proposed to be used.
The fig.
shews the special arrangement for loading trucks when these are pushed in from
the bottom end of belt. When the trucks are pushed in at the belt end in the
ordinary way the shoot B will be put in the line of the fixed plate R and screen S.
The coal slides down the shoot and screen and thence passes on to the hinged
flap T provided with counter weight T whence it gradually falls on the sliding
shoot B by preference of telescopic form which is lowered into the truck on
commencing to fill the latter, and gradually raised as the truck is being filled.
The trap door U is operated by the lever U¹. The sliding shoot B is pulled up and
down by two chains passing round a barrel the shaft of the latter being provided
with a hand wheel V to operate it. When the trucks are let down in the proper
direction the sliding shoot B is in line with the fixed plate or shoot R.
dotted lines shew the sliding shoot drawn out telescopically in the low position.
The coal instead of passing from the fixed shoot R on to a sliding shoot such
The

shoot by an endless belt such as A. Fig. 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
claim is:
1. In combination with a cleaning belt and an endless belt jib end hinged to
its delivery end the application and use of a shoot arranged underneath the jib
end and having its upper end forming a continuation of the upper side of the
cleaning belt, the lower end of jib end and shoot being adapted to be raised and
lowered as required substantially as set forth and for filling a truck by minimum
breakage of coal.
