in the County of Stafford, Chairman and Managing Director of the said Company,
do hereby declare the nature of this invention to be as follows:
This invention has reference to coke conveyors for use in gas works or at bat-
teries of coke ovens to receive the coke as it is discharged from the inclined or
other retorts or furnaces and convey the same outside the retort house to the coke
screening apparatus or to any other place required. Heretofore coke conveyors
have not worked satisfactorily as owing to the fine coke dust working into the
joints of the chains and into other rubbing parts these have soon worn away and
had to be renewed.
My invention enables me to overcome these defects and to simplify the manu-
facture of the conveyor.
In carrying out my invention I provide an open topped cast iron or other suit-
able trough made in lengths as usual and fixed conveniently below the outlet
mouths of the retorts. The bottom of this trough has a raised part running all
along leaving a gutter at each side for the purpose hereinafter described. The
ends of the trough are raised so as to contain a certain depth of water at the
bottom of the trough to receive the coke dust and for the chain to work in. The
raised central part of the trough has or may have boards or iron or steel strips
fixed to it to form a path for the endless chain which extends all along the
bottom of the trough and round the driving wheels or drums as usual at the ends
of the trough and back over rollers under the trough carried by slings from the
same. I make the said chain of a series of ordinary oblong links and flat section
bar links. Each of the oblong links is made from a bar of round iron or steel
bent into the required oblong form and welded, the link being formed with
straight ends to joint with the flat bar links each of which consists of a flat
section bar equal in length to nearly twice the length of the link and of the
proper width to pass through the oblong links the end portions of this flat section
bar being bent over towards each other and about parallel with the bottom of the
link leaving at the top an opening through which the oblong links can be
threaded. This opening is closed over by a cover plate and on the top of the
cover plate there is fixed to each of the Hat links another plate which is of the
proper width to work easily along the trough and is rather longer than two links
so that these plates overlap or abut together. These plates thus form a moving
bottom to the trough on which the coke falls and by which the coke is conveyed
along. Any dust which falls between the sides of the plates and the sides of the
trough falls into the water and into the channels at the bottom of the trough from
whence it is removed by angle iron or other scrapers which at certain intervals
are fixed to the underside of the plates so that as the conveyor is at work con-

page_text: veying the coke along the trough the scrapers also scrape the coke dust along
the channels and deliver the same out of the end of the trough.

I, GILBERT LITTLE, of The New Conveyor Co. Ltd., Brook Street, Smethwick,
in the County of Stafford, Chairman and Managing Director of the said Company,
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 fol-
lowing statement:-
This invention has reference to coke conveyors for use in gas works or at bat-
teries of coke ovens to receive the coke as it is discharged from the inclined or
other retorts or furnaces and convey the same outside the retort house to the coke
screening apparatus or to any other place required. Heretofore coke conveyors
have not worked satisfactorily as owing to the fine coke dust working into the
joints of the chains and into other rubbing parts these have soon worn away and
had to be renewed.
My invention enables me to overcome these defects and to simplify the manu-
facture of the conveyor.
I will describe my invention by referring to the accompanying drawings on
which Fig. 1 is a sectional side elevation of the delivery end portion of a coke
conveyor constructed according to this invention; Fig. 2 is a sectional
side elevation shewing the other end of the same; Fig. 3 is ย
elevation of the same onl line X X of Fig. 1;
Fig. 4 is an end elevation of that end of the coke conveyor represented by Fig. 2;
Fig. 5 is a cross sectional elevation on line YY of Fig. 1 and Fig. 6 shews some
parts of the chain of the coke conveyor on an enlarged scale.

The same letters of reference indicate the same parts in all the figures of the
drawings.
In carrying out my invention I provide an open topped cast iron or other suit-
able trough A made in lengths as usual and fixed conveniently below the outlet
mouths of the retorts. The bottom of this trough has a raised part a¹ (see Fig. 3)
running all along from end to end leaving the gutter a at one side of the raised
part and a similar gutter at the other side of the raised part for the purpose
hereinafter described. The end portions of the trough are raised in an inclined
direction as usual so that the trough will contain a certain depth of water at the
bottom of the trough to receive the coke dust and for the chain to work in. The
water lever is marked B in Figs. 1 and 2. The lower parts of the sides of the
trough A are made vertical at ata to about the level of the plates or moving
bottom C of the conveyor hereinafter described and from this level the sides of
the trough are inclined outwardly at (see Fig. 3). The ends (Fig. 1)
(Fig. 2) of the trough A are open as usual. The raised central part al of the
trough A has or may have boards or iron or steel strips D) fixed to it to form a
path for the endless chain which I will now describe and which extends all along
the bottom of the trough A and round the driving wheels or drums E¹ E² as usual
at the ends of the trough and back over the usual rollers F under the trough A
which are carried by slings from the same (not shewn on the drawing) or other-
wise suitably supported. I make the said conveyor chain of a series of ordinary

page_text: oblong links G alternating with flat section bar links H. Each of the oblong
links G is made from a bar of iron or steel bent into the required form and
welded the link being formed with straight ends g¹ g² to joint with the flat bar
links H. The construction of these flat section bar links H will be clearly under-
stood by an examination of Fig. 6 by which it will be seen that each of them
consists of a flat section bar of iron or steel equal in length to nearly twice the
length of the link and of the proper width to pass through the oblong links G.
The end portions ¹² of this flat section bar are bent over towards each other and
about parallel with the bottom 3 of the link leaving at the top an opening h
through which the oblong links G can be threaded. This opening h* is closed
over by a cover plate I and on the top of the cover plate I there is rivetted to each
of the flat links H another plate J which is of the proper width to work easily
along the trough A and is rather longer than two of the links H so that these
plates Joverlap or they may abut together. Each of the plates J is by prefer-
ence rebated at jl at that edge which is nearer to the link H to which the plate J
is fixed so that the edge of the next plate J will fit on to the rebated edge j¹ and
thus form a continuous bottom to the trough A as shewn in Figs. 1 and 2. The
plates A thus form a moving bottom to the trough A on which the coke falls and
by which the coke is conveyed along the trough. Any dust which falls between
the sides of the plates J and the sides a of the trough A falls into the water and
into the channels a²a, at the bottom of the trough from whence it is removed by
angle iron scrapers K which at certain intervals apart are fixed to the underside
of the plates J so that as the conveyor is at work conveying the coke along the
trough A the scrapers K also scrape the coke dust along the channels a² a³, and
deliver the same out of the end of the trough or into the breeze tank L (see
Figs. 1 and 5) which may be provided so as to form a water well in the bottom of
the trough near the delivery end of the same. The breeze tank L is as shewn in
Fig. 5 made inclined to one side so as to clear the returning conveyor chain
which passes underneath. At the bottom of the breeze tank L there is a water
with a water valve M. It is to be understood that I make no claim in
respect of the breeze tank L and water valve M as part of my invention.
It will be understood that the shaft e¹ on which the drum is fixed is mounted
in the usual bearings and receives rotary motion by gearing from any convenient
source but this gearing forms no part of my invention and therefore no descrip-
tion is necessary.
Also the shaft e² which carries the other drum E2 revolves in
suitable bearings which as usual are provided with screws n to adjust the tension
of the conveyor chain and take up the wear.
The cover plates I may if desired be omitted and the flat section links H be
rivetted directly to the underside of the plates L.
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. The improved coke conveyor chain consisting essentially of alternate round
section links G and flat section bar links H engaging together in combination
with the plates J fixed to and above the flat section links and arranged to abut
or overlap and form a continuous moving bottom to the conveyor trough when in
use therewith, substantially as described.
2. In a coke conveyor the combination of the trough A made substantially of
the cross section described and shewn with upwardly inclined ends, and a coke
conveyor chain consisting essentially of alternate round section links G and flat
section bar links H engaging together, plates J fixed to and above the flat section
links and arranged to abut or overlap and means for moving the chain along the
trough so that the plates will form a continuous moving bottom to the trough,
substantially as described.
3. In a coke conveyor the employment of the conveyor frough A made with
inclined ends and sides and with a raised central path a for the conveyor chain

page_text: to run along and grooves a² a³ at the sides of said path to receive the small coke
dust in combination with scrapers on the conveyor chain arranged to scrape the
coke dust along the channels substantially as described.
4. The improved coke conveyor constructed and arranged substantially as set
forth.
