Improvements in Hot Coke Conveyors.
MAURICE GRAILAM, Black Bull Street, Leeds, Engineer, do hereby declare
the nature of this invention to be as follows:-
The improvements are as follows:-I have a cast iron trough built up in
sections having two sides of suitable shape with deflecting plates attached also
a renewable bottom plate with raised roller paths cast on the same. The moveable
chain to work in this trough consists of one or more strands of steel links, pins,
rollers, or wheels and attached to this chain are moveable steel ploughs for
drawing the coke along the trough. One of the many advantages gained by
this improvement is the protection of the chain from the falling hot coke. The
chain after completing its travel can return either above or below the trough.

MAURICE GRAHAM.
I, MAURICE GRAHAM, of Black Bull Street, Leeds, in the County of York,
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:-
My invention relates to conveyors or conveying apparatus for use in con-
veying hot coke direct from the retorts in gasworks."
DESCRIPTION OF DRAWINGS.
Fig. 1 is a transverse section of my improved conveyor with built-up trough.
Fig. 2 is a partial longitudinal section of same.
Fig. 3 is a plan of one side of moveable chain detached.
Fig. 4 is a transverse section of my improved solid trough.
Fig. 5 is a partial side elevation of same.
Like parts are indicated by like reference letters throughout the several
views.
According to my said invention I employ (see Figs. 1, 2, and 3) a cast-iron
trough made in sections of suitable length, width, and depth, each section being
preferably built up with sides A A and renewable bottom plate B having raised
roller paths C C cast thereon.
Upon these raised paths C C runs a double endless steel chain, each side of
which consists preferably of double links D D, E E, rollers or runners F, and

page_text: pins G. The chain carries, at suitable intervals, detachable and renewable
steel ploughs H (preferably of T-section) for drawing the coke along the trough,
the said ploughs being attached by pins or rivets K in slotted brackets L
formed on the links D).
Overhanging deflecting plates M M are provided to protect the chain from the
falling hot coke, the said deflecting plates being also renewable as required, and
being attachable either to the sides of the trough (as shown in Figs. 1, 2, and 4)
or to the top flanges of the trough (as shown by dotted lines at M in Fig. 4).
The chain, after delivering the coke at the end of the trough, may be returned
either above or below the trough.
In lieu of the built-up trough I may employ if desired (see Figs. 4 and 5) a
trough made in solid cast sections, with the raised roller paths CC, deflecting
plates M M, and double roller chain as before described.
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. In a hot coke conveyor, the employment of a double roller chain running
on suitable paths within a suitable conveying trough and carrying transverse
detachable ploughs, substantially as and for the purpose described, and as illus-
trated at Figs. 1, 2, and 3 of the accompanying drawings.
2. In a hot coke conveyor, the employment of a built-up trough consisting of
sides A A, renewable bottom plate B having raised roller paths CC, and deflect-
ing plates M M, substantially as and for the purposes described, and as illustrated
at Figs. 1 and 2 of the accompanying drawings.
