Complete Specification Left, 18th Nov., 1895-Accepted, 21st Dec., 1895
I, GERALD HENRY BRETON, of 6 Cambrian Terrace, Beeston Hill, Leeds,
in the County of York, Mill Manager, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to a class of elevators used for lifting wet granular
or granulated substances.
Many of these elevators consist of a series of buckets, attached to travelling
bands of leather, or other pliant substance, which are injuriously effected by the
dampness of the material raised.
These bucket-carrying bands, of leather, hemp, cotton, etc., are run on pulleys;
one such pulley being fixed say at the head, and the other at the foot of the lift
supposing the belt to be kept tight, and one of these pulleys suitably revolved, it
follows that the elevator will do its work in a satisfactory manner.
But since the moisture effects a leather belt, for instance, by lengthening it ;
and a hemp belt, as another instance, by shortening it; it will be seen that a
considerable amount of attention must be paid to such elevators in order to get
them to continue to work satisfactorily without damaging their belting.
The object of this invention is to overcome the difficulties last set out, by
providing a plan of keeping the belts dry or practically so.
I carry out my object as follows:-The belt is carried over pulleys as before;
but, instead of attaching the buckets in close proximity to the belt, they are carried
at the end of an intervening arm in each case. These arms in cross-section are
made narrow so that they may pass through a slot in a neighbouring tube suitably
arranged to receive and encircle the travelling buckets. In this tube the wet
material is lifted and is not allowed to come in contact with the belt.
When the buckets are passing over the top centre, or over any other position in
which there is a tendency for the moisture to run down the intervening carrying
arm, I close the opening of the slot with rubber or other shields, which are pushed
sideway's, temporarily, by the passing arms.
The arms may also have shields to turn the water away from the slots, and so, in
some cases, the rubber or other shield at the edge of the slot may be omitted.
Again, suppose the arms to be provided with special shields, then between arm
and arm protecting sheets of suitable material (trough shaped in cross section)
could be slung, leaving them loose enough to allow the arms to pass round" tlie
pulleys without inconvenience. In some of these latter cases, unless otherwise
required, the tubes themselves need not be provided as the water would drain away
to the bottom in the troughs formed by the arms and these draining sheets.

page_text: Improvements in Elevators.
I, GERALD HENRY BRETON, of 6 Cambrian Terrace, Beeston Hill, Leeds, in
the County of York, Mill Manager, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has reference to a class of elevators used for lifting wet granular
or granulated substances.
Many of these elevators consist of a series of buckets, attached to travelling
bands of leather, or other pliant substances, which are injuriously effected by the
dampness of the material raised.
These bucket-carrying bands of leather, hemp, cotton, etc., are run on pulleys;
one such pulley being fixed say at the head, and the other at the foot of the lift;
supposing the belt to be kept tight, and one of these pulleys suitably revolved, it
follows that the elevator will do its work in a satisfactory manner.
;
But since the moisture effects a leather belt, for instance, by lengthening it;
and a hemp belt, as another instance, by shortening it; it will be seen that a
considerable amount of attention must be paid to such elevators in order to get
them to continue to work satisfactorily without damaging their belting.
The object of the invention is to overcome the difficulties last set out, by
providing a plan of keeping the belts dry or practically se.
In order to fully explain my meaning I have annexed a drawing incorporating
my improvements, on which Fig. 1 is a side sectional elevation of the head of such
an elevator, whilst Fig. 1 is that of the foot; the intermediate portion, broken
away, may be of any length. Fig. 2 is a sectional plan. The other figures I refer
to as I proceed. The same letters refer to the same parts in all the figures.
1 carry out my object as follows:-The belt is carried over pulleys B and B' as
before; but, instead of attaching the buckets C in close proximity to the belt, they
are carried at the end of an intervening arm C' in each case. These arms in cross-
section are made narrow so that they may pass through a slot D in a neighbouring
tube E suitably arranged to receive and encircle the travelling buckets. In this
tube the wet material is lifted and is not allowed to come in contact with the
belt.
When the buckets are passing over the top centre, or over any other position in
which there is a tendency for the wet material or moisture to travel down the inter-
vening carrying arm, I close the opening of the slot with rubber or other shields,
which are pushed sideways, temporarily, by the passing arms. These arms may at
that point be shaped to fill the gap left in the parted rubber.
This is clearly shown in Fig. 3, a sectional elevation at right angles to that in
Fig. 1, where d¹ and d are shields of indiarubber which lap over and close the
slot D. These shields are opened by the arm C¹ of the bucket as it passes along, as
shown in the said figure. Here the gap is shown entirely filled by the section of
the arm.
See also Fig. 34 which shows the filling-up-piece of the arm in the other
view on a somewhat enlarged scale.
The arms may also have shields to turn the water away from the slots, and
so, in some cases, the rubber or other shield at the edge of the slot may be
omitted.
Such an arrangement is shown in sectional elevation in Fig. 4, where C2 is the
shield on the arm C¹. Fig. 5 is a sectional plan and Fig. 6 a side sectional elevation
of this same arrangement. The shield has its sides so formed that water cannot
travel down the arm C¹ without being drained off to one of the four points c, c, c
or . These points drain the water off to the sides of the tube, and as the slot D
is in the centre, and has projecting lips F, F, it follows that all moisture will drain

page_text: to the bottom of the tube leaving the belt dry. The bottom of the elevator must
of course be suitably drained in order to prevent any accumulation of water.
There may also be a second shield C³ with a cup as shown which may be useful
when an arm is passing vertically over the top drum. Also the buckets may have
moisture collecting points C8 at their sides as shown in Figs. 4 and 6.
In some cases a cup-like shield C2 may be arranged say outside the tube E with
a spout (or spouts) C³, to lead the water to one side away from the belt, as shown
in Fig. 7 in plan view.
Belt tightening arrangements should preferably be fitted at the head, as at that
position there will be less water to give trouble at the sliding joints, such as will be
necessary for varying the length of the tube, after the manner shown at G, G
in Fig. 1.
Fig. 8 shows in a plan view how a bucket may be slung on an arm C¹ at the side
of a belt with a view to keeping the water away from the said belt; or, for
balancing the overhanging weight, a bucket may be hung on each side, as shown
by the additional dotted lines in the same figure.
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
1. The improvements in belt-driven elevators, for raising wet substances,
substantially as described herein and shown on the drawing, with the object and
for the purpose set forth.
2. In a belt driven elevator lifting wet substances, the use of a bucket mounted
on a long arm (C¹), working in a drained tube (E) with or without rubber shields
for guarding the slot (D), substantially as described and shown, with the object
and for the purpose set forth.
3. In a belt-driven elevator lifting wet substances, the use of water diverting
shields on the arms C¹ of the buckets C, substantially as described and shown, with
the object and for the purpose set forth.
4. In a belt-driven elevator lifting wet substances, the plan of catching any
moisture that may run down the arm C¹ and piping it off to one side, substantially
as described and shown in Fig. 7, with the object and for the purpose set forth.
5. In a belt-driven elevator the plan of slinging buckets for lifting wet substances
at the side or sides of a belt, the long arm (C¹) allowing the bucket and its
moisture to be kept at a distance on either side, substantially as described and
shown in Fig. 8, with the object and for the purpose set forth.
