Improved Appliance for Scraping the Insides of Retorts in which
Gas is Produced from Steam and Hydro-carbon and the Simul-
taneous Removal of the Deposit therefrom.
1, FREDERICK POOL, of Tonbridge Road, Maidstone, in the county of Kent, Manu-
facturer do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct or arrange a series of skeleton spikes
and with scraper ends to a bar or rod, by which said scraper spikes can be operated
from outside the retort, to not only scrape off the incrustation or carbonacious deposit
but to creep it to the front or to the back of the retort so as to keep the passage
clear for the heat of the retort for converting the agents into a gas, the spikes or
legs of the apparatus acting as checks or baffles to the direct passage of the mixture
which obstruction causes the agents to commingle or mix and become atomized so
that vapour or gas so formed can be led into a storage vessel or gasometer for
after use.
The feet or bottom of the spikes are set to angles, which as the apparatus is rotated,
gradually force the powder or scale to one end of the retort tube.

Gas is Produced from Steam and Hydro-carbon and the Simul-

I, FREDERICK POOL, of Tonbridge Road, Maidstone, in the county of Kent, Manu-
facturer, do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
he following statenient :--
The object of this invention is to construct or arrange a series of skeleton spikes
and with scraper ends to a bar or rod by which said scraper spikes can be operated
from outside the retort to not only scrape off the incrustation or carbonaceous
deposit but to creep it to the front or to the back of the retort so as to keep the
passage clear for the heat of the retort for converting the agents into a gas, the spikes
or legs of the apparatus acting as checks or baffles, to the direct passage of the
mixture which obstructions cause the agents to commingle or mix and become
atomized so that vapour or gas so formed can be led into a storage vessel or gasometer
for after use.
The feet or bottom of the spikes are set to angles which as the apparatus is rotated
gradually force the powder or scale to one end of the retort tube.
An apparatus such as above described is shown in the annexed drawing in which is
a retort A set in Brickwork B and enclosed in a furnace C and flue way D.
E is the hydrocarbon inlet and F the steam inlet which agents commingle in the
retort A and is converted into a gas which is led away by the pipe G to a gasometer
or other receiver.
Within the retort A is a shaft H worked from the outside by a pulley I said shaft H
having a series of skeleton spikes J with scraper ends for scraping the inside of the
retort and prevent the adhesion of incrustation, which as formed is caused to travel to
the front of the apparatus for the powdery particles to be discharged into a receiver K
from which they can be removed on opening the door L at any convenient time.
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 I
claim is
Scraping the insides of retorts, in which gas is produced from a combination of
steam and hydrocarbon, by a skeleton frame scraper, which also moves the deposit or
refuse to one end as and for the purpose described.
