PROVISIONAL SPECIFICATION.
Improved Method of Removing and Discharging the Material
Used in Gas Purifiers.
I WILLIAM SMITH MORLAND Gas Engineer Gas Works Hempstead Gloucester do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of removing and discharging the
material used in Gas Purifiers, by which manual labour is largely dispensed
with.
In carrying this invention into practice I provide a machine preferably portable
running upon a suitable gantry and rails placed on each side of the purifiers. The
machine consists of a framework having formed in it suitable bearings to carry the
necessary shafts, upon one of these latter is keyed a drum or tumbler which drives the
chains of a bucket ladder similar to those used in dredgers and elevators, the ladder
being suspended in such a manner as to permit its lower end being raised and lowered
at will to suit the depth of purifiers. The buckets deliver their contents into a box or
trough fitted with a worm creeper or its equivalent which then delivers the material
by a spout at the side of machine. Suitable means are provided to enable the bucket
ladder to be traversed across from one side of the purifier to the other and also to
travel the entire machine upon the rails of gantry and to force the buckets against the
material. The machine may be driven either by hand or by power derived from a
steam or other engine. When driven by power it is preferably arranged to receive
motion from an endless rope running alongside of gantry in the manner commonly
used to drive power travelling cranes.

Used in Gas Purifiers.
I WILLIAM SMITH MORLAND, Gas Engineer Gas Works Hempstead, Gloucester, do
hereby declare the nature of this invention for REMOVING AND DISCHARGING THE
MATERIAL USED IN GAS PURIFIERS and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement
My invention has for its object the construction of apparatus for removing, and
discharging the material used in gas purifiers. For this purpose I provide a machine
which is portable, running upon rails placed on each side of the purifiers.
The machine consists of a framework, having formed in it suitable bearings to carry
the necessary shafts. Upon a shaft is keyed a drum, or tumbler, which drives the
chain of a bucket ladder, the ladder being suspended by a chain and blocks; so as
to permit its lower end being raised or lowered at will to suit the depth of material in
the purifier. The buckets deliver their contents into a box, or trough, fitted with a
worm creeper, or its equivalent, which then delivers the material by a spout at the
side of the machine.
The bucket ladder is fixed on a stand sliding on a bed, and is traversed from one
side of the purifier to the other by means of right, and left handed worms, having
feathers within them, the worms work on a shaft with a keyway cut to correspond to
the size of the feathers in them, the keyway being cut the entire length of the shaft.
The worms work into worm wheels of the same pitch on seperate shafts each of the
shafts having a pinion wheel fixed on them, which works into a rack between the bed
of the stand, clutch couplings are fitted to the worm wheels and when these are put in
gear in the right handed worm wheel, gives the ladder a motion towards one side, and
when in the left towards the other.
The machine is kept up to the face of the material by a rope, or clain, fastened on a
crab, or winch, so that it can be drawn up when required. The machine may be
driven either by hand, or power derived from a steam, or other engine, when driven by
power, it is driven by an endless rope running alongside of rails.
In order that my invention and the means by which the same is to be carried into
effect, may be thoroughly understood, I will proceed to describe the same in detail,
referring in so doing to the accompanying drawings which are to be taken as part of
this specification and read therewith, and in which like parts are marked throughout
with the same reference letter.
Fig. 1 is an end elevation.
Fig. 2 is a vertical section.
Fig. 3 is a plan.
A and A2 are frameworks, having formed in them bearings to carry the necessary
shafts. On the shaft B is keyed the driving wheel (the spur wheel and the worm
creeper E which revolves in the trough F discharging the material at the spout 3, the
spur wheel D works into the wheels and H which are keyed on the shafts I and J,
on the shaft the worms K and I, which are fitted with feathers working in a keyway

page_text: cut the entire length of the shaft. I, these worms work into the worm wheels M and N
which revolve loosely on the shafts O and P and are put in gear by the clutch couplings
Qand R which are fitted with feathers to suit the keyways cut on the shafts O and I'
and slide backwards and forwards. On the shafts O and Pare keyed the pinion wheels
S and T represented by the dotted lines in Figs. 1 and 3, and work into the rack U
giving a traverse motion to the bucket ladder V from one side to the other when
geared up properly. The letters B1 and B2 represent the bed on which the stand C
slides that carries the bucket ladder V. On the shaft J is carried the wheel W fitted
with a feather to correspond to a keyway cut the entire length of the shaft J, to enable
the wheel W between the frames C to slide along the shaft, when the bucket ladder is
traversing, the wheel W works into the wheel X revolving the wheel X which works
into the wheel Y and revolves the tumbler Z and the buckets 4 on the endless chain 5.
6 represents the chain, and blocks, by which the ladder V can be raised, or lowered, to
suit the depth of material in purifier. 7 represents a sectional view of the purifier.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is,
The combination of a bucket ladder, the traverse motion, the worm creeper or its
equivalent, and the method of driving the machine, substantially as described with
reference to the accompanying figures.
