Improvements in Apparatus for Injecting Liquids into Gas
Retorts.
1, ROBERT GOOD, Manager of the Gas Works, Carshalton, in the County of Surrey,
do hereby declare the nature of this invention to be as follows:
It is a difficult and somewhat dangerous operation to introduce with ordinary
apparatus liquids such as crude petroleum or shale oil into a hot gas retort.
According to this invention employ a syringe or single acting force pump. The
nozzle of this pump is provided with an india rubber or other surface which when
pressed against a cock in the retort lid forms a tight joint. The mouth of the cock is
made to a knife edge to form a tight joint on the surface. The piston of the pump is
provided with an india rubber or other surface which at the end of the stroke
comes against a ring inside the pump barrel surrounding the opening to the
nozzle.
The pump is filled with the liquid it is desired to inject into the retort and its nozzle
is pressed against the cock in the retort lid. The cock is then opened and the liquid
forced in. At the end of the stroke of the pump the surface on the piston
comes against the ring surrounding the nozzle and makes a tight joint thus
preventing any back flow until the cock is shut and the pump can be removed.

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:
It is a difficult and somewhat dangerous operation to introduce with ordinary
apparatus liquids such as crude petroleum or shale oil into a hot gas retort.
According to this invention I employ a syringe or single acting force pump. The
nozzle of this syringe or pump is provided with an india rubber or other surface
which when pressed against a cock in the retort lid forms a tight joint. The mouth of
the cock is made to a knife edge or other form to make a tight joint on the surface.
The piston of the syringe or pump may be provided with an india rubber or other
surface which at the end of the stroke comes against a ring inside the barrel surrounding
the opening to the nozzle.
The syringe or pump is filled with the liquid it is desired to inject into the retort
and its nozzle is pressed against the cock in the retort lid. The cock is then opened
and the liquid forced in. At the end of the stroke of the syringe pump the surface
on the piston comes against the ring surrounding the nozzle and makes a tight joint
thus preventing any back flow until the cock is shut and the syringe pump can be
removed.
Figure 1 is a longitudinal section of a retort with the syringe I employ-a is the
nozzle of the syringe, it carries an india rubber ring b-c is a cock fixed in the lid of
the retort, its mouth is made to a knife edge as shown-d is the piston of the syringe
and e is a sheet of india rubber carried by it.
Figure 2 is a section of my single acting force pump. The nozzle carries an
india rubber ring g which as before comes against the mouth of the cock in the lid of
the retort. This however in place of being a knife edge is flat and has a recess in the
middle as shown in Figure 3 to receive the nozzle. The pump is inside the vessel /
which contains the liquid to be pumped. The piston k is perforated and carries on its
top a flap valve l.

page_text: 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
1. Apparatus for injecting liquids into gas retorts consisting of a syringe or pump
whose nozzle is adapted to make a tight joint against the mouth of a cock in the retort
substantially as described.
2. Apparatus substantially as described and shown in Figure 1.
3. Apparatus substantially as described and shown in Figures 2 and 3.
