do hereby declare the nature of this invention to be as follows:-
According to this invention a bucket is raised, emptied and lowered automatically
by the continuous rotation of a shaft.
Preferably two buckets are employed suspended by a chain from the same barrel
in such manner that one is lowered whilst the other is being raised.
The apparatus can very conveniently be actuated by a horse walk in which
case the motor shaft is vertical and has fixed to it a bevel wheel gearing with
two pinions running loose on a horizontal shaft on which is a sleeve free to
slide longitudinally but not to rotate relatively to it. At the ends of the sleeve
are ratchet teeth engaging alternately with similar teeth on the pinions. The
sleeve is automatically moved longitudinally after a certain number of revolutions
by a lever (actuated as hereinafter described) so reversing the direction of rotation
of the horizontal shaft. The barrel is driven by chain or other gear from the
horizontal shaft.
Projecting over the edge of the well or shaft up which the material is being
raised are two horizontal bars carried by arms, pivotted at the edge of the well.
The bars should be as near as possible to without touching the chain. The
buckets carry trunnions just above their centres of gravity which work in bearings
at the lower ends of straps attached to the ends of the chain. These straps
are so formed that when one of them comes up to the horizontal bar it is turned
so that the vertical plane in which it lies is parallel to the bar. Each bucket
has a pair of hooks on its edges at the ends of the diameter at right angles to
the trunnions. Each branch of the rope passes through a forked lever connected
by links to the lever of the reversing clutch and near each end of the chain is
a bulb or stop of such size that it cannot be drawn through the fork.
The action of the apparatus is as follows:-
As the motor shaft is turned one of the buckets is raised and the other lowered.
After a time the strap from which the rising bucket is suspended comes against
the horizontal bar turning the bucket into the proper position, the bar lying
across its upper edge. As the bucket continues to rise the hook at one side
engages with the bar which is lifted turning about its pivot thus drawing the
bucket towards the edge of the well and tilting it, causing it to discharge its
contents into a shoot or other receptacle. The bulb on the chain has also
engaged with the fork of the lever raising the latter and it is so placed that
immediately the bucket has been emptied the lever is sufficiently raised to throw
over the clutch reversing the motion of the barrel so that the bucket is lowered
again and the other raised.

page_text: I, GAVIN SIBBALD JONES, of 20 South Street, South Kensington, S.W.,
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 :-
According to this invention a bucket is raised, emptied and lowered automatically
by the continuous rotation of a shaft.
Preferably two buckets are employed suspended by a chain from the same barrel
in such manner that one is lowered whilst the other is being raised.
The apparatus can very conveniently be actuated by a horse walk as shown in
the drawings Figure 1 being a side elevation, Figure 2 an end elevation and
Figure 3 a plan.
The motor shaft a is vertical and has fixed to it a bevel wheel b gearing with
two pinions ce running loose on a horizontal shaft d on which is a sleeve e free to
slide longitudinally but not to rotate relatively to it. At the ends of the sleeve
are ratchet teeth (or a clutch) engaging alternately with similar teeth on the
pinions c c. The sleeve e is automatically moved longitudinally after a certain
number of revolutions by a leverf (actuated as hereinafter described) so reversing
the direction of rotation of the horizontal shalt d. The barrel g is driven by a
chain or other gear from the horizontal shaft d.
Projecting over the edge of the well or shaft up which the material is being
raised are two horizontal bars jj carried by arms j pivotted at the edge of the
well. The bars j should be as near as possible to without touching the chain k.
The buckets carry trunnions just above their centres of gravity which work in
bearings at the lower ends of straps m attached to the ends of the chain k. These
straps are so formed that when one of them comes up to the horizontal bar; it is
turned so that the vertical plane in which it lies becomes parallel to the bar.
Each bucket has a pair of hooks on its edges at the ends of the diameter
at right angles to the trunnions. Each branch of the rope k passes through a
forked lever n connected by links o to the lever f of the reversing clutch and near
each end of the chain is a bulb or stop k of such size that it cannot be drawn
through the fork n.
The action of the apparatus is as follows:-As the motor shaft a is turned
one of the buckets is raised and the other lowered.
After a time the strap m from which the rising bucket is suspended comes
against the horizontal bar j turning the bucket into the proper position, the bar
lying across its upper edge. As the bucket continues to rise the hook at one
side engages with the bar which is lifted turning about its pivot thus drawing
the bucket towards the edge of the well and tilting it, causing it to discharge
its contents into a shoot p or other receptacle. The bulb k¹ on the chain k has
also engaged with the fork of the lever n raising the latter and it is so placed
that immediately the bucket has been emptied the lever n is sufficiently raised
to throw over the clutch lever reversing the motion of the barrel g so that
the bucket is lowered again and the other raised.
In some cases it is desirable that the shoots p should be thrust inwards over the
well and below the bucket which is being tilted in this case the shoots are suspended
from links which are prolonged downwards and connected to the bottoms of the
tail ends of the arms j which are longer than shown in the drawings.
In order to prevent the vertical shaft reversing by the weight of the bucket
when stopping or in case of accident, a suitable pawl or friction stop may be
applied.

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. The method substantially as described whereby a bucket is automatically
raised emptied and lowered by the continuous rotation of a shaft.
2. The combination of the hooks on the bucket and the horizontal bar pivotted
to the edge of the well substantially as described.
3. The combination of the reversing gear with the lever operated by parts
moving with the bucket substantially as described.
4. Apparatus for raising water and other materials substantially as described
and shown in the drawings.
