PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Charging Gas Producers and Gas or
Shale-oil Retort Furnaces with Hot Residual Coke.
I, GEORGE ROBERTSON HISLOP, Engineer and Manager, Corporation Gas Works,
Paisley, Renfrewshire, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide simple and efficient means for directly
charging gas producers and gas or shale-oil retort furnaces with hot residual coke
from the retorts heated by such furnaces in lieu of as is usual transferring the hot
coke into bogies and charging the furnaces therefrom.
This
To that end I cast or otherwise form a mouthpiece upon a crown plate which is
placed and bolted on top of the projecting brick breastwork of the retort oven and
over the ordinary cleaning and charging doors and form therefrom a shoot extending
downwards and rearwards through the upper front wall of the furnace at such an
inclination as to discharge the fuel at or near the middle of the furnace.
mouthpiece is furnished with a self sealing door operated by levers and has hinged
or jointed to it a hopper which may be raised and held by a catch close up against
the front of the retorts or lowered and retained by the same or a separate catch
in a position in which it forms an inclined plane over which and through the
mouthpiece the hot residual coke drawn from one or more of the retorts is dis-
charged directly into the producer or furnace. In order to bind the projecting
breastwork there are bolted to the crown plate on either side down to the floor
line cast iron plates with flanges at front going over and bolted to the front plate
of the producer or furnace.

Improvements in Apparatus for Charging Gas Producers and Gas or
Shale-oil Retort Furnaces with Hot Residual Coke.
I, GEORGE ROBERTSON HISLOP Engineer and Manager, Corporation Gas Works,
Paisley, Renfrewshire, 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 :—
The object of my invention is to provide simple and efficient means for directly
charging gas producers and gas or shale-oil retort furnaces with hot residual coke
from the retorts heated by such furnaces in lieu of as is usual transferring the hot
coke into bogies and charging the furnaces therefrom.
To that end I cast or otherwise form a mouthpiece upon a crown plate which is
placed and bolted on top of the projecting brick breastwork of the retort oven and
over the ordinary cleaning and charging doors and form therefrom a shoot extending
downwards and rearwards through the upper front wall of the furnace at such an
inclination as to discharge the fuel at or near the middle of the furnace. This mouth-
piece is furnished with a self sealing door operated by levers and has hinged or jointed
to it a hopper which may be raised and held by a catch close up against the front of
the retorts or lowered and retained by the same or a separate catch in a position in
which it forms an inclined plane over which and through the mouthpiece the hot
residual coke drawn from one or more of the retorts is discharged directly into the
producer or furnace. In order to bind the projecting breastwork there are bolted to
[DC

page_text: the crown plate on either side down to the floor line cast iron plates with flanges at
front going over and bolted to the front plate of the producer or furnace.
The producer charging arrangement is placed in front of and attached to any oven
of gas or shale-oil retorts, but more particularly to ovens heated by means of a
producer placed immediately under the retorts such as in the settings on the
Regenerative system described in the Specification of Letters Patent No. 2207
of 1884, and in order to its more convenient application the front portion of the
producer is preferably built in projection beyond the front line of the oven as
represented in the accompanying drawings in which figure 1 is a front elevation and
figure 2 a side elevation showing the hopper and part of the front of the retort oven
figure 3 being a detailed view of the door covering the shoot leading from the hopper.
The crown of the producer is terminated preferably in an arch of brickwork A and
through the top a suitable port or shoot B is formed for the passage of the coke into
the producer. The upper or arched portion is bound together by metal jacket plates C
securely bolted to front plate I) of producer and front of oven E respectively the said
front plate being furnished with an upper door F to facilitate the cleaning of and a
lower one not shown for withdrawing the ashes from the producer. On the top of
said jacket plates and over the opening B for the passage of the coke a cast iron crown
plate G with doorway H preferably oval in form is fixed on and at a suitable angle or
inclination from the face of the oven. The doorway H is furnished with ears and
stop snugs and is planed on its face and fitted with a corresponding door or disc I
hinged on a pin i passing through the one ear and held by a jamming lever J on the
other. The disc I at back passes under pocket plates j fixed on snugs to define the
travel and fix the position of the disc. On top of the pins i passing through the ears
and hinging the disc and jamming lever adjustable journals K are formed to receive
and carry the axis pin 7 of the charging hopper L. The latter is preferably ovular in
form and expanded at the mouth to the width of the retort or retorts above. The
hopper is placed preferably immediately under the central retorts of the oven, and by
casting the hinged oscillating disc I sufficiently thick on lower edge so as to reduce
the angle of inclination it, when shut, holds the outer edge of the hopper up to or
within the line of the retort mouth pieces, and simultaneously with allowing the disc I
to fall out of position by reversing the jamming lever J the hopper L also falls to the
necessary angle to receive the contents of the retorts above it which are shot into the
producer and at such an angle as to deposit the same in the centre thereof.
This arrangement may be applied to any ordinary setting of gas or shale-oil retorts
and be so modified as to suit same.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The combination of parts constituting the improved apparatus for charging gas
producers or heating furnaces of gas and other retorts with hot residual coke
substantially as described with reference to the accompanying drawings.
2. In gas and other retort ovens the combination of a charging shoot provided with
a door and a hopper pivotted thereover and operating substantially as hereinbefore
described.
