the Office of the Commissioners of Patents on the 28th June 1883.
WILLIAM AUBERT, Junior, of Crossgates House Balham in the county of Surrey
Engineer IMPROVEMENTS CONNECTED WITH PORTABLE OR TABLE FOUNTAINS AND
IN THE CONSTRUCTION OF PUMPS TO BE USED THEREWITII
The object of this invention is to construct or arrange a portable or table
fountain in such a manner that the jet is maintained by the compression of air
acted on by a column of water
The pump which is of special construction has no valves but the liquid after
flowing into the centre portion is forced by a piston capable of being moved to
either end for forcing the water through the tube provided for it. The movement
of the piston in either direction withdraws the air from the opposite tube. The
opposite ends of the tubes terminate in a close vessel which receives the water
from the pump and from which vessel the water is expelled from a nozzle by the
pressure of the air which has been compressed by the water falling from the open
bason into the lower portion or base which also forms a close vessel.
The water in its turn on leaving the nozzlo serves to compress the air in the
base until it becomes full and the top vessel empty the piston is then moved to and
fro to recharge the upper close vessel and to empty the lower one Sufficient water
being left in the open bason to recommence the action which continues until the
lower bason is again full and so on

WILLIAM—AUBERT-Junior-of-Crossgate's House Balham in the county of
IMPROVEMENTS CONNECTED WITH PORTABLE OR TABLE
FOUNTAINS AND IN THE CONSTRUCTION OF PUMPS TO BE USED THEREWITH
Surrey Engineer
The object of this invention is to construct or arrange a portable or table
fountain in such a manner that the jet is maintained by the compression of air
acted on by a column of water
The pump which is of special construction or adaptation has no valves but the
liquid after flowing into the centro portion of the cylinder is forced by a piston or
pistons capable of being moved to either end for forcing the water through the
tube or tubes provided for it. The movement of the piston in either direction
withdraws the air from the opposite tube. The opposite ends of the tubes
terminate in the upper part of a close vessel which receives the water from the
pump and from which vessel the water is expelled from a nozzle by the pressure of
the air which has been compressed by the water falling from the open bason into
the lower portion or base which also forms a closo vessel.
The water in its turn on leaving the nozzle serves to force the air from the
lower vessel in the base into the upper vessel by a-connecting pipe so that the air
becomes compressed therein. As the lower vessel fills with water the piston or
pistons is or are then moved to and fro to recharge the upper close vessel with
the water from the lower one. Sufficient water is left in the open bason to
recommence the action which continues until the lower bason is again full
and so on.
The annexed drawings represent the fountain at Figure 1 in section and with
the upper vessel empty Figure 2 being also in section at right angles. A is
the lower vessel at the lower part of which is the pump cylinder or barrel B
provided with apertures at about its central upper part for the passage of tho
water from the lower vessel into it. CCare pistons in the barrel Band connected
by the rod D so that they can be moved to and fro by hand or by clockwork as
and when desired. E E are pipes connected at either end to the pump barrel and
terminating within the upper vessel F so that the water can be forced up into
that vessel at each traverse of the pistons the air that is within said vessel F
being compressed thereby. G is a pipe connecting the two vessels A, F, to enable
a portion of the air to pass into the lower vessel A during the pumping oporation.
His the nozzle or jet tube whose lower end terminates just above the bottom of
the vessel F so that the jet under the internal pressure of air within the upper
vessel F and of its dome I may issue and fall as a spray into the bason J. Kis
the flow back pipe from the bason to the lower vessel A which back flow is in
proportion to the gradual decroase of pressure through the gradual increase of air
space within the vessel A consequent of the change in the quantity of water in the
same. The lower end of the back flow pipe terminates near the bottom of the lower
vessel A
It will be observed that both vessels A and F are hermetically sealod except by
the connecting pipes which permits of the water being changed in the nanner
above explained and when equilibrium is effected it will be necessary for the
pump pistons to be again worked to restart the jet which continues until the next
equilibrium and so on.

page_text: I have shown two pistons on the same rod but one long piston will suffice the
piston being of such a longth as to pass the perforations by which the two ends of
the barrel become alternately charged with water during the motion to enable the
required quantity to be forced up the pipes E. E¹.
.
I do not limit myself to the shape of the fountain nor to the position of
the several pipes or pump because they can be arranged in any other suitable
manner,
Having now described the nature of my said invention and in what manner
the same is to be perforined I declare that I claim
The portable or table fountain arranged and acting in the manner described and
substantially as shown in the annexed drawings.
Secondly I claim In connection with a portable or table fountain the centrally
perforated pump barrel (without valves) by which the water can charge
the same from the lower vessel said barrel having pipes attached
communicating with a separate vessel as and for the purposes described
and substantially as shown in the annexed drawings.
In witness whereof I the said William Aubert Junior have hereunto set my
hand and seal this twenty seventh day of December in the year of our Lord
One thousand eight hundred and eighty three
