page_text: I GUSTAVUS ADOLPHUS JOHN SCHOTT of West End Mills Richmond Road
Bradford Yorkshire; Managing Director of the Corporation of Schott Brothers,
Limited, of West End Mills aforesaid do hereby declare the nature of this invention
to be as follows:-
This Invention relates more particularly to improvements in portable pumping
apparatus and has for its object to afford increased facilities for drawing off liquids
from barrels and other vessels and to prevent waste.
My first improvement consists in fitting a rotary or other pump with a receiver
provided with a funnel and also if desired with a strainer and lid―The pump shaft
passes through the funnel of the receiver and has a metal boss secured thereto by a
clamp, thumb screw or other equivalent means-This boss is mounted on standards
attached to a base plate having an aperture therein to permit the pump shaft and
funnel, and likewise the chain presently mentioned to be introduced there-
through into the barrel or other vessel to which the apparatus is to be applied.
Fitted in the boss is a screw jack which works up and down therein―This
screw jack is fitted at its lower end with a chain carrying a cross bar slotted or
perforated at one end to allow of a cord or string being attached thereto.
The operation of this part of my invention is as follows:-The pump together
with the chain, cross bar and funnel are introduced into the barrel or other vessel
through the bung hole or other outlet opening therein the base plate resting on
the top of the vessel The chain is then drawn up until the cross bar comes in
contact with and lodges against the underside of the top of the barrel or other
vessel The chain is then attached to the base of the screw jack and tightened up
thereby thus holding the apparatus in position and rendering it sufficiently rigid
to allow of the pump being worked-The pump is then operated and any overflow
of the oil or other liquid is caught in the receiver and conducted back into the
barrel jar or other vessel through the funnel fitted thereto.
The cord or string attached to the slotted or perforated end of the cross bar
allows of the easy withdrawal of the apparatus from the barrel or other vessel.
My second improvement consists in fitting a rotary or other pump with an
auxiliary pump so as to prime such rotary or other pump mechanically instead of
Duin 77

page_text: by hand thus materially economising labor and providing a more certain and
regular means of raising the oil or other liquid The auxiliary pump may be worked
either by mechanical or manual power as preferred-In order to obtain increased
suction the discharge pipe of the main pump may be fitted with a valve so arranged
as to be raised by the liquid when being pumped out-This valve when down
closes the discharge pipe and prevents the ingress of the air therethrough.
An alternative arrangement consists in elongating the suction pipe of the main
pump so that it extends above the pump and then bends downwards while the
mouth of the discharge pipe is placed at a higher level than the pump by which
sufficient liquid will remain in the pump after use to keep it primed.
Either of the two last mentioned methods may be applied to a rotary or other
pump either when used independently or in conjunction with an auxiliary force
pump as herein before mentioned.
My improvements may either be used as a whole or the economising and self-
priming arrangements may each or both be dispensed with as desired.
My invention combines the advantages of safety economy, cleanliness and
facility.

I GUSTAVUS ADOLPHUS JOHN SCHOTT of West End Mills Richmond Road
Bradford Yorkshire Managing Director of the Corporation of Schott Brothers
Limited of West End Mills aforesaid, 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 relates more particularly to improvements in portable pumping
apparatus and has for its object to afford increased facilities for drawing off liquids
from barrels and other vessels and to prevent waste.
The letters of reference in the following description refer to corresponding letters
in the accompanying drawings.
My first improvement consists in fitting a rotary or other pump with a receiver A.
provided with a funnel C and also (if desired) with a strainer B and lid L-The
pump shaft D passes through the funnel of the receiver and has a metal boss E
secured thereto by a clamp, thumb screw or other equivalent means-This boss is
mounted on standards F attached to a base plate G having an aperture therein to
permit the pump shaft and funnel and likewise a chain H-presently more particu-
larly mentioned to be introduced therethrough into the barrel or other vessel to
which the apparatus is to be applied.
Fitted in the boss is a screw jack I which works up and down therein―This
screw jack is fitted at its lower end with a chain H carrying a cross bar K slotted
or perforated at one end to allow of a cord or string being attached thereto.
The operation of this part of my invention is as follows-The pump together
with the chain cross bar and funnel are introduced into the barrel or other vessel
through the bung hole or other outlet opening therein-the base plate resting on
the top of the vessel-The chain is then drawn up until the cross bar comes in
contact with and lodges against the underside of the top of the barrel or other
vessel-The chain is then attached to the base of the screw jack and tightened up
thereby; thus holding the apparatus in position and rendering it sufficiently rigid
to allow of the pump being worked-The pump is then operated and any overflow
of the oil or other liquid is caught in the receiver and conducted back into the
barrel jar or other vessel through the funnel fitted thereto.
The cord or string attached to the slotted or perforated end of the cross bar
allows of the easy withdrawal of the apparatus from the barrel or other vessel.
Figures 1 and 2 of the accompanying drawings illustrate the improved con-
struction and arrangement herein before described. The improved economising and
fastening apparatus above described may be fitted separately if desired.
My second improvement consists in fitting a rotary or other pump with an
auxiliary pump so as to prime such rotary or other pump mechanically instead
of by hand thus materially economising labor and providing a more certain and

page_text: regular means of raising the oil or other liquid-Such auxiliary pump may be
worked either by mechanical or manual power as preferred.
This improved construction and arrangement is illustrated at Fig. 3 of the
accompanying drawings A¹ is a rotary pump the axle a whereof is operated by a
crank handle B fitted to one end of such axle and having an eccentric disc C¹
mounted upon its other end.
An auxiliary lift and force pump D¹ is fitted inside the shaft E' of the rotary
pump This auxiliary pump is provided with a suitable valve at its lower extremity
while its piston F' (which is pierced and is likewise provided with a suitable valve)
is worked up and down by nicans of the before mentioned eccentric disc alternately
acting upon two collars G¹ and G which are fixed on the piston rod H' of such
auxiliary pump Such piston rod passes through a stuffing box I which closes the
upper extremity of the pump shaft of the auxiliary pump whilst the liquid lifted
by such auxiliary pump after passing through the piston and filling the portion
of the pump shaft above such piston flows through the bend or branch pipe K and
round the rotary pump A¹ entering such pump at the top and thus keeping it
primed whilst the pump is being worked-At the same time the rotary pump also
comes into action the liquid entering through the suction pipe E-L is a discharge
pipe fitted to the combined pumps A¹ and D¹-In order to obtain increased suction
such discharge pipe may be fitted with a valve M so arranged as to be raised by the
liquid when being pumped out-This valve when down closes the discharge pipe
and prevents the ingress of the air therethrough.
An alternative arrangement consists in elongating the suction pipe of the main
pump so that it extends above the pump and then bends downwards while the
mouth of the discharge pipe is placed at a higher level than the pump by which
sufficient liquid will remain in the pump after use to keep it primed-This modified
construction and arrangement is illustrated at Fig. 4 of the accompanying drawings
wherein A is the rotary pump-B2 the suction pipe-and C² the discharge pipe.
Either of the two last mentioned methods may be applied to a rotary or other
pump either when used independently or in conjunction with an auxiliary force
pump as herein before mentioned.
My improvements may either be used as a whole or the economizing and self
priming arrangements may each or both be dispensed with as desired.
My invention combines the advantages of safety economy, cleanliness and
facility.
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° Fitting a rotary or other pump with an economising apparatus, consisting of
a receiver A and funnel C and providing the same when desired with a strainer B
and lid L all constructed arranged combined and fitted substantially in the manner
and for the purposes hereinbefore described and shewn at Fig. 1 of the accom-
panying drawings.
2° Fitting a rotary or other pump (either separately or in combination with
the economising apparatus hereinbefore described and claimed) with a fastening
apparatus consisting of a bess E-standards F base plate G-chain H screw jack I
and cross bar K all constructed arranged combined and fitted substantially in the
manner and for the purposes hereinbefore described and shewn at Figs. 1 and 2 of
the accompanying drawings.
3° Fitting a rotary or other pump with an auxiliary pump worked either by
mechanical or manual power substantially in the manner and for the purposes
herein before described and shewn at Fig. 3 of the accompanying drawings.
4° Fitting the discharge pipe of a rotary or other pump with a shut off valve
substantially in the manner and for the purposes herein before described and shewn
at Fig. 3 of the accompanying drawings.

page_text: 5° The alternative construction and arrangement herein before described and shewn
at Fig. 4 of the accompanying drawings.
6° The application of the various improvements hereinbefore described and
claimed either combined as a whole or separately and in part only to a rotary or
other pump either when used independently or in conjunction with an auxiliary
force pump substantially in the manner herein before described.
