page_text: Improvements in Bucket Water Lifts.
I, CHARLES THOMAS BURGESS, of Victoria Works, Brentwood, in the County of
Essex, Engineer, do hereby declare the nature of this invention to be as follows:-
The improvements relate especially to water lifts in which water is raised in
buckets situated between and secured to a pair of endless chains which pass
around revolving sprocket wheels and which hang down from them to a depth
sufficient to enter the water to be raised and in which the water delivered from
the buckets as they pass over the top of the wheels falls down directly between
the wheels into a trough below-the trough being about at the level of the axis
of the wheels and made to extend outwards to one side whilst the wheels are
driven by gearing from the opposite side. The improvements are also applicable
to similar lifts in which a single wheel and chain is used.
According to my present invention I affix to the wheel or wheels shields or
guard plates to come just in front of the buckets and at a short distance from
them at the time when they are emptying and so cause the water as it issues
from the buckets to be deflected and directed downwards towards the centre of the
trough and prevent its being thrown forwards and beyond the side edge of the
trough should the wheels be driven quickly.
By these means not only may the wheels be driven at a greater speed than
hitherto and the lifting capacity of the lifts be so correspondingly increased but
the shields or guards serve in addition as wind guards and prevent the water
being blown over the side or the closed end of the trough.
By these means the efficiency of the pumps at times when high winds are
blowing is also increased.
The shields or guard plates may be fixed to cross bars which tie together the
two wheels if two wheels are used or to similar bars which extend from the outer
ends of the spokes and carry a single wheel if a single wheel is used.

I, CHARLES THOMAS BURGESS, of Victoria Works, Brentwood, in the County of
Essex, 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:—
The improvements relate to water lifts in which water is raised in buckets

page_text: usually situated between and secured to a pair of endless chains which pass
around revolving sprocket wheels and which hang down from them to a depth
sufficient to enter the water to be raised and in which the water delivered from
the buckets as they pass over the top of the wheels falls down directly between
the wheels into a trough below-the trough being about at the level of the axis
of the wheels and made to extend outwards to one side whilst the wheels are
driven by gearing from the opposite side.
My invention is also applicable to water lifts in which a single chain and
single sprocket wheel are used and in which the water similarly falls down
directly into a trough below.
According to my present invention I affix to the wheel or wheels shields or
guard plates to come just in front of the buckets and at a short distance from
them at the time when they are emptying and so cause the water as it issues from
the buckets to be deflected and directed downwards towards the centre of the
trough and prevent its being thrown forwards and beyond the side edge of the
trough should the wheels be driven quickly.
By these means not only may the wheels be driven at a greater speed than
hitherto and the lifting capacity of the lifts be so, correspondingly increased but
the shields or guards serve in addition as wind guards and prevent the water
being blown over the side or the closed end of the trough..
By these means the efficiency of the pumps at times when high winds are
blowing is also increased.
When two sprocket wheels are used the shields or guard plates may be fixed
to cross bars which tie together the two wheels.
In the case of water lifts with a single sprocket wheel the shields or guard
plates may be fixed to similar bars which form continuations of the spokes and
carry the sprocket wheel.
The drawings annexed illustrate constructions in which two sprocket wheels
are used.
Figure 1 is a front view of a construction in which the shields or guards are
fixed to cross bars so placed as to pass near the edges of the trough-the trough
is shewn in section.
Figure 2 is a vertical section of the same.
Figures 3 and 4 are corresponding views of a construction in which the shields
or guards are fixed to cross bars connecting the outer rings of the sprocket wheels.
In these figures a a are two endless chains passing around two sprocket
wheels b b. cc are the buckets situated between the chains and secured to them.
d is the trough and e a bevil wheel on the boss to which the wheels are secured
and by which the wheels are driven-f f are the shields or guards which are
bolted to cross bars 9 which extend across from one wheel to the other. fis
a side flange at one or both ends of each shield to restrain water from escaping
sidewise and dropping down outside the closed end of the trough.
The guard plates might if desired be made in one piece with the cross bars
either by using iron or steel rolled to a suitable section, or they might be cast
in one.
In the case of rolled iron or steel, the side flange or flanges fl might be bolted
or rivetted on, or the flange at the gearing end might be formed upon the central
boss to which the cross bars are bolted.
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: In water lifts of the kind herein before set forth the affixing shields or guards
to the wheels to come in front of the buckets as water is being discharged from
them and prevent its being thrown forwards beyond the trough substantially as
herein before described.

herein before set forth and illustrated in the drawings annexed.
