Improvements in Apparatus for Pumping, Raising, or Elevating
Liquids, Semi-solid Substances, Grain, or the like.
We, HENRY CLAUGHTON, of 20, Milroy Street, Liverpool, in the County of
Lancaster, Naval Architect, and MAZZINI STUART, of 20, Castle Street,
Liverpool, in the County of Lancaster, Shipowner, do hereby declare the nature
of this invention to be as follows:-
This invention has for its object a rotary pump or elevator for raising or
elevating liquids, semi-solid substances (e.g. palm oil, lard and treacle) grain or
the like.
In carrying the invention into effect, the plan we prefer is to form the pump or
elevator of a cylindrical drum or flanged disc having transverse slots at intervals
in its periphery or rim, and a series of blades or arms radiating from a shaft or
axis on which each one capable of rotating independently. A portion of these
blades projects through the transverse slots in the periphery or rim, and the result
is that when the drum is rotated it will also rotate the arms, but these arms, being
mounted and rotating eccentrically to the drum, will alternately be projected from
the periphery of the drum and then be retracted as the drum and arms rotate.
The drum together with its sliding arms are enclosed in a casing or shell, this
casing fitting pretty closely the side faces of the drum but leaving a circum-
ferential channel part way round the periphery of the drum through which the
substances to be raised are passed. One part of the casing is however left open,
so that the periphery of the drum and the projecting arms are exposed, and are
enabled to come directly in contact with the substances to be raised or elevated.
The axes of the drum and arms are so arranged that the arms project furthest at
the part where the substance enters the channel at the point where the casing is
left open, and the casing is so formed that the blades practically fill the said
channel for some little distance, and then retract into the drum so as to leave a
clear space for the substance to be moved forward. The driving shaft on which
the drum is fixed is preferably mounted in bearings on one side of the casing and
provided with a pulley or other suitable means for driving from any suitable source
of power. The arms are mounted on an axis preferably on the opposite side of
the casing to that on which the axis of the drum is located.
The mode of action is as follows:-
The apparatus is placed in such a position that the substance which is to be
raised, comes directly in contact with the blades or arms at that part where the
casing is left open. Each successive blade which at this part protrudes from the
drum, scoops or forces along the substance into the circumferential channel formed
by the casing and the periphery of the drum, whence it is driven onward through
a length of pipe to the required height or distance. The blades as the drum
rotates gradually retreat into the drum, the blades behind feeding in fresh
material, and raising the material in front of it forward, then gradually
retracting into the drum so as to leave a clear space for the forward passage of
the material. The blades if desired may be somewhat curved or bent at or near
their ends so as to better. scoop or accumulate the material and force it into the
channel. It will be obvious that the channel along which the substance is raised
may be fitted with a valve, if so desired, so as to prevent the substance flowing

page_text: back if the elevator is stopped working. It is obvious that the apparatus will
not only pump up liquids, but is specially adapted for working semi-solid
substances such as palm oil, lard, and treacle. It can also be adapted for
elevating grain, in which case we propose to introduce a worm or spiral for
feeding the grain forward after the blades or arms have raised it a given distance.

Improvements in Apparatus for Pumping, Raising, or Elevating
Liquids, Semi-solid Substances, Grain, or the like.
We, HENRY CLAUGHTON of 20 Milroy Street, Liverpool, in the County of
Lancaster, Naval Architect and MAZZINI STUART of 20 Castle Street, Liverpool
in the County of Lancaster, Shipowner, 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:-
This invention has for its object a rotary pump or elevator for raising or
elevating liquids, semi-solid substances (e.g. palm oil, lard and treacle) grain or
the like.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which
Figure 1 is a sectional front elevation of our apparatus arranged vertically
with a horizontal shaft ;
Figure 2 a cross section on the line a b;
Figure 3 another arrangement of the drum and arms;
Figure 4 a sectional elevation on the line cd of our apparatus fitted with a
vertical driving shaft ;
Figure a sectional plan.
Referring to Figures 1 and 2, A is a cylindrical drum or flanged disc having
transverse slots at intervals in its periphery or rim, and B a series of blades or
arms radiating from the shaft or axis C, on which each one is capable of rotating
independently. A portion of these blades B projects through the transverse slots
in the periphery of the rim A, and the result is that when the drum A is rotated,
it will rotate the arms B, but as the drum rotates concentrically in the casing and
the arms are mounted and rotate eccentrically thereto, the arms will alternately
be projected from the periphery of the drum A, and then be retracted as the drum
and arms rotate. The drum A together with the arms B are enclosed in a casing
or shell D, this casing fitting pretty closely to the side faces of the drum A, but
leaving a circumferential channel É round the periphery of the drum A, through
which the substances to be raised are passed. One part of the casing at E is
however left open, so that the periphery of the drum and the projecting arms are
exposed and are enabled to come directly in contact with the substances to be
raised or elevated. The axis A' of the drum and the axis C of the arms, are so
arranged that the arms project farthest at or about the part where the substances
enter the channel E, namely at E', and the casing is so formed that the blades
practically fill the said channel E for some little distance, and then retract into
the drum A so as to leave a clear space for the substance to be moved forward.
The driving shaft A' on which the drum is fixed is mounted in bearings F on one
side of the casing, and provided with a pulley G or other suitable means for
driving from any suitable source of power. The arms B are mounted on the
shaft which is secured at H on the opposite side of the casing to that on which

page_text: the axis of the drum is rotated, the rotation of the drum causing the arms to
rotate likewise.
The mode of action is as follows:-
The apparatus is placed in such a position that the substance which is to be
raised comes directly in contact with the blades or arms B at E', where the casing
is left open.
Each successive blade which at this part protrudes from the drum A
scoops or forces along the substance into the circumferential channel E formed by
the casing D and the periphery of the drum A, whence it is driven onward
through a length of pipe I to the required height or distance. The blades B, as
the drum A rotates, gradually retreat into the drum A, the blades behind feeding
in the fresh material, raising the material in front of it forward, then gradually
retracting into the drum A so as to leave a clear space for the forward passage of
the material. The blades B are preferably curved or bent somewhat at or near
their ends, so as to better scoop or accumulate the material and force it into the
channel. It will be obvious that the channel I along which the substance is raised
may be fitted with a valve, if so desired, so as to prevent the substance flowing
back if the elevator is stopped working.
The apparatus indicated in Figures 4 and 5 is substantially the same as that
previously described, the only difference being that the drum and blades are
arranged horizontally with a vertical shaft, the same reference letters indicating
like parts in these figures as in the preceding ones. The channel I through which
the substance is raised is curved at right angles passing upwards in the direction
of the driving shaft. It is obvious that instead of leaving the side of the casing
open, as indicated in these figures, it may be formed as shown in dotted lines at J
in Figure 1, and provided with a flange in front of the aperture for coupling to a
suction pipe.
It is obvious that the separate arms may radiate from annular
hubs a, all mounted and rotating separately upon the eccentric disc b forming part
of the drum A as depicted in Figure 3. The result obtained is substantially the
same as when mounted on a shaft C. It is obvious moreover that the apparatus is
well adapted for lifting water for irrigation, for fire-engines or for propelling
liquids any given distance, and that it is also specially well adapted for working
semi-solid substances, such as palm oil, lard and treacle. It can also even be
adapted for elevating grain, in which case we propose to introduce a worm or
spiral for feeding the grain forward after the blades or arms have raised it a given
distance.
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 improvement in rotary pumps or elevators, which consists in mounting
concentrically witbin a circular casing a cylindrical rotary drum or hollow disc
smaller in diameter than the interior diameter of the casing, and having trans-
verse slots at intervals in its periphery or rim, and arranging in combination
therewith a series of blades or arms radiating from a centre eccentric to the said
drum and casing, and projecting through the transverse slots aforesaid, whereby as
the drum rotates in the casing, the arms will be rotated also and be alternately
projected from the drum and retracted into the same for the purpose set forth.
2. In a rotary pump or elevator having a circular casing or shell with inlet and
outlet orifices, a cylindrical rotary drum mounted concentrically within the said
casing, and of smaller diameter so as to leave a circumferential channel between the
periphery of the drum and the inside of the casing, in combination with a series
of arins or blades all rudiating from one common centre and projecting through
transverse peripheral slots in the drum, the centre from which said arms or blades
radiate being eccentric to the axis of the casing and drum, whereby during
rotation each blade will in turn be projected from the drum in such manner as to
scoop or force the liquid or other substance to be elevated into the circumferential
channel aforesaid, whence it is driven onward to the required height or distance

page_text: through the outlet orifice, each of the said blades in turn gradually retreating
into the drum, as those behind feed into the channel fresh material substantially as
described.
3. The general combined arrangement and construction of parts forming our
-compound rotary pump or elevator substantially as set forth.
