Improvements in Means or Apparatus for Effecting the Turning or
Stirring of Oxide of Iron, Lime, or other matters.
We,
FREDERICK DEACON MARSHALL of Copenhagen in the Kingdom of
Denmark, and of 3 Storeys Gate, in the City of Westminster, Civil Engineer, and
EMIL BLUM of Martinikenfelde, Berlin, in the German Empire, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to obviate the necessity for hand labour in
gasworks in revivifying and turning oxide of iron, turning lime during the process
of slacking, or for turning granulated or pulverised material, as applied to other
industries.
Generally speaking the machine consists of framing at either end of a platform
carrying toothed gearing and other parts around the toothed gearing of which
passes an endless chain, this chain is also attached to a travelling carriage which
is thus made to traverse the platform on a line or lines of rails, from end to end.
This travelling carriage may consist of a hollow shaft carrying the revolving
shovels or scoops and an internal shaft, to the ends of this shaft are attached the
revolving, travelling and reversing arrangements, to be more particularly
described.
The machinery is set in motion by any suitable engine or motor having attach-
ment to one of the standards.
The material to be turned is spread upon the platform or other surface and the
machine set in motion. The centre shaft moves forward, the shovels revolving at.
the same time, so as to deliver material clear of and behind the carriage; by this
means the whole mass is thoroughly and equally turned. On reaching the end of
the platform the direction of rotation, and at the same time the relative position
for scooping, of the shovels is reversed, and the traveller caused to move in the
opposite direction. The progress of the traveller forwards and backwards and the
revolving of the shovels in either direction is rendered automatic, and the machine
needs no attention beyond regulating the motive power.
This action is brought about as follows:-
Inside a hollow shaft carrying the working shovels, there is another shaft. On
this inner shaft parts are applied so that they pass through a corresponding slot in
the outer shaft, and are attached to reversible shovels. An endless chain and
ratchet arrangement grips the inner shaft, and the motive power is transferred to
the outer shaft by means of the parts or arms fixed on to the inner shaft. The
shovels revolve in one direction as long as the motion of the carriage continues in
the one direction, from right to left for example.
When however the motion is reversed by the traveller reaching the end of the
platform or surface traversed on the left, the hollow outer shaft, and the internal
shaft, become disconnected, the outer shaft is brought to a standstill, the reversing
gear is set in motion, and the shovels are reversed and work in the direction from
left to right.
This action brings the opposite slot in the outer shaft in connection with the
inner shaft, causing the shovels to work in the desired direction.
The reversal of the operating edges of the shovels or scoops is attained by
means of levers and lost motion párts which cause the tilting of these scoops as the
reversal of direction of motion of the carriage takes place.

Improvements in Means or Apparatus for Effecting the Turning or
Stirring of Oxide of Iron, Lime, or other matters.
We FREDERICK DEACON MARSHALL of Copenhagen in the Kingdom of
Denmark, and 3 Storeys Gate in the City of Westminster, Civil Engineer, and
EMIL BLUM of Martinikenfelde, Berlin, in the German Empire, Civil Engineer
do hereby declare the nature of this invention and in what manner the same
to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of this invention is to obviate the necessity for hand labour in gas
works in revivifying and turning oxide of iron, turning lime during the process of
slacking or for turning granulated or pulverized material, as applied to other
industries and to provide means or apparatus for mechanically turning and
revivifying such materials used in gas works, or for turning and mixing pulverized
or granulated material used in other industries.
Generally speaking the machinery consists of two standards with toothed gearing
fixed at either end of the platform. Round the toothed gearing of the standards
an endless chain passes conveying motion to a travelling carriage, which is thus
made to traverse the platform on a line of rails from end to end. This travelling
carriage consists of a hollow shaft carrying revolving shovels, and an internal
shaft. To the ends of this shaft are attached the revolving and travelling
arrangements and the reversing arrangements to be more particularly described.
The machinery is set in motion by any suitable engine or motor having
attachment to one of the standards.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a side view Fig. 2 a plan view Fig. 3 is a portion (to left hand) in
section Fig. 4 is a portion (to right hand) externally of an end view of an
arrangement of mechanism according to the invention.
Fig. 5 is a side view partly in section of a set of shovels and their gear
separately.
Fig. 6 is a similar view to the last, of a modification of the parts thereby
shewn.
The material to be turned or mixed is spread upon the platform and the machine
set in motion.
The centre shaft moves in the direction of the arrow
4), the shovels
revolving at the same time, by this means the whole mass of material spread on the
platform is thoroughly mixed and turned. On reaching the end of the platform
the revolution of the shovels is reversed and the travelling shaft caused to move
in a contrary direction. On reaching the further end of the platform, the reversing
gear is again automatically set in motion, and the revolving shovels made to move
forward again, their action at the same time being reversed.
This reversing action is brought about as follows. Inside the hollow shaft a,
carrying the working shovels there is another shaft b. On this shaft the parts c
and d Figs. 4 and 6, and f Figs. 3 and 5 are fixed, so that c, f, pass through a
corresponding slot in shaft a and are attached to the reversible shovels s.
The motive power tiz.:-the endless chain and ratchet arrangement grips the
inner shaft and the motive power is by means of the parts c, f, transferred to
tube a aud to the shovels-which remain in position as long as the motion of the
carriage continues in the direction of
→ 1.
When however the motion is reversed the hollow shaft a and the internal shaft b
are brought to a standstill the reversing gear is set in motion and the shovels are
so reversed as to work in the direction of arrow 2 (>
2).

page_text: This action brings the opposite side of the slot in shaft a in connection with
the parts c, fon tube shaft thus causing the shovels to move in the desired
direction.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what.
we claim is :-
1. The arrangement or combination and use of reversible travelling and
shovelling gear as means or apparatus for effecting the turning or stirring of
oxide of iron, lime or other similarly granular or pulverized materials used in gas.
works or other places by machinery substantially as and in the manner herein
described and shewn.
2. The arrangement or combination and use of parts of apparatus for use in
shovelling, turning or stirring oxide of iron or other similarly constituted materials.
used in gas works and other places so that said parts may be reversible and capable
of co-operating substantially as and for the purposes set forth.
3. In the revivifying and turning of oxide of iron and other such materials
used in gas works the employment of reversible travelling and shovelling gear
substantially as set forth.
