FREDERICK JOHN BROUGHAM of 46 Lincolns Inn Fields in the County of
Middlesex, "IMPROVEMENTS IN APPARATUS FOR TRANSFERRING LIQUID FROM ONE
VESSEL OR PLACE TO ANOTHER (a communication from Messieurs Hazard et Cie"
of Rue de Vauvillers, Paris in the Republic of France)
"
This invention relates to apparatus for transferring liquid from one vessel or
place to another.
For this purpose there is provided a flexible pipe of material such as caoutchouc,
arranged in U form, and resting in a frame or bed of similar form which serves as
a support. The lower part of the said pipe situated below the horizontal diameter
of the circle described by the axes of rollers mentioned below is circular. The
upper ends are curved outward from the said diameter and are supported in
collars or bearings by clip joints. Lengthening tubes connect to these joints.
Concentric with the curved lower part of the pipe is the axis of a wheel or shaft
carrying arms. Anti frictional pressure rollers having their axes at equal distances
from this centre, and each able to turn freely on its own axis, roll on the upper
part of the curved pipe so as to flatten it. The spindle of each pressure roller is
fixed to the wheel or to one of the arms before mentioned.
Two wedges are provided and are so arranged in relation to the bent pipe and
its bed or frame that when the wedges are in place the rollers will act as aforesaid
on the pipe but when the wedges are withdrawn the pipe will enter recesses in the

page_text: frame as the rollers pass and will thus not be flattened where these recesses occur.
It will thus be seen that if the rollers are brought into positions opposite these
recesses (the wedges being withdrawn) the pipe will serve as a simple passage
between its two extremities.
The communication between the supplying vessel and the receiving vessel being
established through the apparatus above described the arms or wheel carrying the
pressure rollers are or is caused to turn, then the pressure rollers expel the air from
the pipe and the apparatus becomes primed. The wedges are then removed.
When there is not a sufficient difference of level to maintain the flow of liquid
through the apparatus if the wheel be again rotated after replacing the wedges the
pressure rollers will expel the liquid from the pipe as they previously expelled the
air and the apparatus thus works as a simple pump.
The whole is mounted on a frame with shafts and can be easily travelled on two
wheels.

FREDERICK JOHN BROUGHAM, of 46 Lincolns Inn Fields, in the County of
Middlesex, "IMPROVEMENTS IN APPARATUS FOR TRANSFERRING LIQUID FROM ONE
VESSEL OR PLACE TO ANOTHER,” A communication from Messieurs Hazard et Cie.,
of Rue de Vauvillers, Paris, in the republic of France
This invention has for its object to transfer or remove liquid by means of a
specially constructed syphon adapted to serve also as a pump, if required.
In describing this invention reference will be made to the accompanying drawings
of which Fig. 1 is partly an elevation and partly a section of the apparatus,
Fig. 2 a cross section along line A B. of Fig. 1, and Fig. 3 a cross section of one
of the movable wedges C.
The apparatus, which may be called a syphon-pump, comprises chiefly a U shaped
tube A made of indiarubber or any other suitable elastic material and representing
an inverted syphon.
The lower part of the syphon, namely that which is situated below the horizontal
diameter passing through O, is circular. The two extremities, which are situated
at the same height, are held in suitable bearings or bushes, and are connected with
extension pipes by means of screw joints. The syphon rests in the channel
bearing B.
In the centre of the eircle formed by the lower part of the syphon tube is placed
a shaft O carrying a fly-wheel adapted to be turned by hand.
On two arms of the flywheel, diametrically opposite each other, and at equal
distances from the centre, are secured 2 friction rollers G G which turn loosely on
their axles and are arranged in such a manner as to pass over the upper surface of
the syphon so as to compress and flatten the same when the fly wheel is turned.
At the extremities of the horizontal diameter passing through O are situated the
wedges C C, which may be removed for the purpose of allowing the syphon to
expand in such a manner, as to prevent a sensible diminution of the sectional area,
when the friction rollers pass over the portion of the syphon formerly backed by
the wedges.
The apparatus thus constructed works in the following manner.
After the distributing and receiving vessels have been connected through the
apparatus, the fly-wheel carrying the friction rollers G G is turned. Owing to the
pressure of the friction rollers G G the air is forced out of the syphon which
presently commences to suck in liquid.
After the syphon has been thus filled, the friction rollers are replaced in their
horizontal position by turning the fly-wheel, care being taken to first remove the
wedges, so as to prevent the compression of the tubes by the friction rollers, which
would arrest the circulation of the liquid. The apparatus then works like an
ordinary syphon as long as there is a difference in the level of the inflowing and
outflowing liquid.
When the syphon ceases to work, the fly wheel is turned, and the friction rollers
force out the liquid in the same manner as they had previously forced out the air,
whereby the syphon is transformed into a pump.
The apparatus may be fixed or movable, and mounted on any suitable frame.
In the accompanying drawing the apparatus is mounted on wheels.
Having now described the invention as communicated to me by my foreign
correspondents, I wish it to be understood, that I claim :

page_text: 1. The combination of an inverted syphon A of indiarubber or other suitable
elastic material, with two compressing rollers G G adapted to roll along the
said syphon so as to flatten the same and drive out the air, and two removable
wedges C, substantially as and for the purpose described.
2. The combination of inverted syphon A, with channel-bearing B, removable
wedges, C, compressing rollers G, and mechanism for carrying said rollers
along the said syphon, substantially as and for the purpose described.
In witness whereof I, the said Frederick John Brougham, have hereunto set
y hand and seal this twenty fifth day of August A D 1883.
