Improvements relating to Apparatus for Washing Coke
and other Materials.
We, JAMES EDWARD JOSELIN, of 81, Bennerly Road, New Wandsworth, London,
S.W., EDWARD LIVINGSTONE JOSELIN, Engineer, of 298, Albert Road, Aston, in
the County of Warwick, and MATTHEW BROWN WILD, of 7 York Road Erdington,
in the County of Warwick, do hereby declare the nature of this invention to be
as follows;-
This invention consists of improvements relating to apparatus for washing coke
and other materials, our object being to construct simple and convenient machines
for passing the coke or other material through the washing box and rapidly and
efficiently cleansing the same.
In carrying our invention into effect we employ a continuous band or conveyor
provided with vanes or bucket like projections, the band being so arranged that
when it is driven or set in motion the vanes or buckets passing along with the
under side of the belt draw the coke or other material through the washing box
and carry it out at the discharge side or end. The coke or other material is fed
into one side or end of the washing box either continuously or intermittently
and as it floats on the surface of the separating liquid it is conveyed towards the
opposite side or end by the band or conveyor hereinbefore described, and is
carried up an inclined plane or trough and caused to pass over the top of the
washing box into the delivery shoot.
The dirt or non-floating material accumulating at the bottom of the washing
box is removed by means of a suitably arranged elevator or worm, or discharge
apertures with trap doors are provided for such purpose.
Instead of employing a continuous belt or conveyor as hereinbefore described
we sometimes arrange that the coke or other material shall be lifted from the
washing box by an Archimedean screw or worm by scoops or buckets fitted at the
outer ends of radial arms which are revolved with their central supporting shaft.
During their revolution the arms dip into the washing box and after propelling
the coke or other material through the separating liquid, lift it clear of the box,
and by a lateral motion which is imparted to the arms in any convenient manner
as they leave the box the coke or other material is discharged, on the continued
rotary movement of the arms, at the required position.

We, JAMES EDWARD JOSELIN, Engineer, of 81, Bennerly Road, New Wands-
worth, London, S.W., EDWARD LIVINGSTONE JOSELIN, Engineer, of 298, Albert
Road, Aston, in the County of Warwick, and MATTHEW BROWN WILD, Engineer,
of 7, York Road, Erdington, in the County of Warwick, 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:-

In the accompanying sheet of explanatory drawings to be hereinafter referred
Figure 1 is a side elevation, Figure 2 a plan, and Figure 3 an end view of a
coke washing machine constructed in accordance with our invention.
The same reference letters in the different views indicate the same parts.
At Figure 3.a portion of one of the side plates of the washing box extension is
removed to show its interior.

In carrying our, invention, into effect we employ continuous chains, bands, or
conveyors, as A having vanes or propellers as B pivotted thereto, the chains
being so arranged that, when driven or set in motion, (in the direction indicated
by the arrows at Figure 1), the vanes or propellers passing along with the under-
side of the chains drop, into the vertical position as illustrated and draw the coke
or other material through the washing box C and carry it out at the discharge
side or end. The coke or other material is fed over the shoot D into the washing
box either continuously or intermittently, and as it floats on the surface of the
separating liquid it is conveyed towards the opposite side or end of the box by
the propellers B and discharged on to the delivery shoot E. The bottom plate C
of, the portion of the washing box along which the vanes or propellers travel is
inclined as indicated at Figure 1.
The dirt or non-floating material accumulating at the bottom of the washing
hox gravitates to the sump or extended portion C2 of the box, and is removed
therefrom preferably by means of the chain of elevating buckets, such as illus-
trated, and discharged down a shoot as F. The bottom plate C3 at the coke
admission end of the washing box is inclined towards the sump C2 as shown at
Figure 3.
We sometimes arrange for the introduction of a stream or jets of water or
other, liquid, into the washing box C beneath the shoot D for the purpose of
varying the extent of the washing or separation of the coke from the dirt or other
matter. For this purpose we preferably employ a perforated pipe as H into
which water is admitted at one end as hand is discharged through the perfora-
tions as indicated by the arrows at Figure 2. If the coke is to be washed or
separated in the most effective manner we so turn or rotate the pipe H as to bring
the perforations to the underside, and we vary the direction of discharge of the
jets between such position and the position indicated in the drawings according
to the extent of washing or separation required. "On a portion of the outer end
of the pipe. H we attach a pointer or indicator as J to show the direction of
discharge.
Both the coke propeller chains A and the chains of clevating buckets are driven

pulleys G G.
Instead of employing a continuous chain conveyor as hereinbefore described,
we sometimes arrange that the coke or other material shall be lifted from the
washing box by an Archimedean screw or worm, or by scoops or buckets fitted at
the outer ends of radial arms which are revolved with their central supporting
shaft. During their revolution the arms dip into the washing box and after pro-
pelling the coke or other material through the separating liquid, lift it clear of
the box, and by a lateral motion which is imparted to the arms in any ordinary
manner as they leave the box the coke or other material is discharged on the
continued rotary movement of the arms, at the required position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
Machines for washing coke and other material constructed substantially in the
manner described and as illustrated.
