PROVISIONAL SPECIFICATION.
Improvements in and Apparatus for Charging Inclined Gas Retorts.
1, MAURICE GRAHAM, of 88A Leadenhall Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the improvements in and apparatus for charging
inclined gas retorts.
Over the beds or bench of inclined retorts settings large coal storage tanks or
hoppers are usually, fixed and underneath these tanks are measuring chambers.
These latter are either fixed or movable, as occasion requires. Sometimes trucks
are used for the same purpose, i.e., of holding or measuring the charges of coal.
These measuring chambers which form part of the charging apparatus are divided
into three classes and have top and bottom doors, slides or valves provided which
are as follows:-
1. Connected together by means of a lever or levers and travel in opposite
directions, i.e., when the top door is open the bottom one is shut or vice versa.
2. They are not connected, but are worked independently of one another by
means of two or more handles or levers.
3. It is found necessary sometimes, especially when movable trucks or waggons
are used, to only have one door, slide valve or the like at the lower end.
My improvement consists of inserting one or more movable plates or arms in
the lower half of this measuring chamber, and just above the bottom slide. This
plate or plates, work on a hinge or hinges fixed to one or more of the sides of the
tank in any convenient manner, and is provided with a weighted lever or spring
balance. The object of this is to prevent the coal from falling from the chamber
before the slide is full open; at the same time, to prevent the slide being shut
before the whole of the coal has fallen from the chamber, this is effected in the
following manner:- -When the coal is deposited in the aforesaid chamber, the
weight of it resting on the movable plate or plates presses the same down upon
the slide or valve underneath; at the same time covering up the full opening.
Directly the door is full open, this plate or the like falls and allows the coal to flow
out of the chamber; the plate also acting as a stop prevents the slide from being
shut while the coal is dropping.
Directly the coal has run out of the chamber the weighted lever, or the spring,
which may be both attached directly or indirectly to the centre axle upon which
this movable plate works, immediately raises the latter; the slide then can be
pushed back and the bottom of the chamber is again closed. A fresh supply of
coal is then run in ready for the next charge..
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials, and parts, or combination of parts of the levers, locking gear
or the like, may be varied in many ways within the scope of my invention.
Dated this 10th day of February 1894.

page_text: Improvements in and Apparatus for Charging Inclined Gas Retorts.
I, MAURICE GRAHAM, of 88A Leadenhall Street, in the City of London,
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 particularly relates to the improvements in and apparatus for
charging gas retorts.
Over the beds or bench of retort settings large coal storage tanks or hoppers are
usually fixed and underneath these tanks are measuring chambers. These latter
are either fixed or movable, as occasion requires. Sometimes tracks are used for
the same purpose, i.e., of holding or measuring the charges of coal.
The measuring chambers which form part of the charging apparatus are divided
into three or more classes and have top and bottom doors, slides or valves provided
which work as follows:-
1. The latter may be connected together by means of a lever or levers and travel
in opposite directions, i.e., when the top door is open the bottom one is shut or
vice versa.
2. The slides &c. are not connected but are worked independently of one another
by means of two or more handles or levers.
3. It is found necessary sometimes, especially when movable trucks or waggons are
used, to only have one door, slide, valve or the like at the lower end.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing, reference being had to letters and figures
marked thereon.
Fig. 1, is a longitudinal section of a single falling flap apparatus.
Fig. 2, is a part in transverse section and part in elevation of Fig. 1.
Fig. 3, is a longitudinal section of a double falling flap apparatus.
Fig. 4, is a part in transverse section and part in elevation of Fig. 3.
Parts of the figs. are broken off for want of space.
or
My improvement consists of inserting one or more movable plates or falling
flaps e in the lower half of this measuring chamber b below the storage tank a just
above the bottom slide f. This plate or falling flaps e, work on a pivot, hinge
hinges fixed to one or more of the falling flaps e of the tank or chamber b in any
convenient manner, and is provided with a weighted lever d and weight c or spring
balance. The object of this is to prevent the coal or other material from falling
from the chamber 6 before the slide fis full open; at the same time, to prevent the
slide being shut before the whole of the material has fallen from the chamber b,
this is effected in the following manner :- -When the material is deposited in the
aforesaid chamber b, the weight of it resting on the movable plate or falling flap e
as in Figs. 1, and 2, or flaps e, e, as in Figs. 3, and 4, presses the same down upon
the slide or valve funderneath; at the same time covering up the full opening.
Directly the door is full open, this flap e or flaps e, e, falls and allows the material
to flow out of the chamber 6; the flap e also acting as a stop prevents the slide from
being shut while the material is dropping.
'
In Fig. 4, I adopt a spiral spring 9 on an axle h or bar with or without a weight c
or lever d.
g
The hereinbefore described apparatus may be constructed of any well known
shape and form for ensuring the measurement of any class of material into various
given quantities.
Directly the material has run out of the chamber the weighted lever d, or the
spring 9, which may be both attached directly or indirectly to the centre axle h

page_text: upon which this movable plate works; immediately raises the latter; the slide f
then can be pushed back and the bottom of the chamber is again closed, and a fresh
supply of material is then run in ready for the next charge.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials and parts, or combination of parts of the levers, locking gear
or the like, may be varied in many ways within the
scope of my invention.
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. In an apparatus for charging retorts, the combination of a falling flap e or
flaps e, e, working on a pivot, hinge or hinges, with a weight c attached thereto by
a lever d for raising the flap to its original position within a measuring chamber,
substantially as herein described and according to the accompanying drawing.
2. In an apparatus for charging retorts, the combination of a flap e or flaps e, e,
with a spiral spring g wound round the axle / or attached to same directly or
indirectly with or without a weighted lever for the purpose of raising the flap or
flaps to its original position within a measuring chamber, substantially as herein
described and according to the accompanying drawing.
3. In an apparatus for charging retorts, the combination of the various parts as
illustrated in Figs. 1, and 2, substantially as described.
4. In an apparatus for charging retorts, the combination of the various parts as
illustrated in Fig. 3, substantially as described.
5. In an apparatus for charging retorts, the combination of the various parts
as illustrated in Fig. 4, substantially as described.
6. In any apparatus for measuring given quantities of any material, the com-
bination of the various parts as illustrated in Figs. 1, 2, 3 & 4, substantially as
described.
