I, GUSTAVUS ADOLPHUS JOHN SCHOTT, of West End Mills, Richmond Road,
Bradford, in the County of York, Manufacturer do hereby declare the nature of my
invention for "IMPROVEMENTS IN PUMPING APPARATUS USED FOR TRANSFERRING
OILS AND OTHER LIQUIDS FROM ONE VESSEL TO ANOTHER, to be as follows:-
U
The first part of my invention consists of an apparatus the main features of
which are illustrated by the accompanying drawing Fig. 1. which represents a
vertical section through the centre of my apparatus. I wish it however to be
understood that I do not confine myself to the precise details shewn as they are
susceptible of variation.
A is a Rotary Reversible Pump standing upright provided with the openings C & D
and containing, the toothed wheels F & G which gear with each other and are fixed
on and revolving with the axles I & H.
Either of these axles. may be turned by means of a winch or other mechanism
fixed on one end of it which projects from the interior of the case A, when the
wheel mounted con such axle. revolves with it and gearing into the other wheel,
imparts a rotary motion to the latter also.
2.
According as one or other of the axles I & H is turned by means of the winch,
one of the openings D & C will be the inlet and the other the outlet of the pump.
Into these openings the hollow spouts or arms D' and C¹ are screwed, each of
which forks into two mouths M, N. & K, L, all provided with screwthreads, so that
hose can be attached to them by means of a screw-coupling.or they can be closed by
screw-caps when not required.

The Pump is mounted on the stand B which is fixed upon the centre of the top X
of the rectangular tank Q, which, in order to be more readily moveable from place to
place may be mounted on wheels.
The tank Q thus serves for a stand or pedestal to the Pump, which might how-
ever also be mounted on. an ordinary bench. or other, stand, but the tank serves
some, further uses which render it preferable to a stand or support, which serves no
other purpose but that of a support.
The two side-portions of the top X are each surrounded by a raised rim and
sloping towards a central opening (T & U) in the manner indicated in the drawing,
over which the mouths N & L of the Pump are placed at a convenient distance to
admit of vessels being placed on the top X and under these mouths.

The central. openings T & U are so arranged that perforated metal-discs (see W
Fig. 1.) may be placed over them or they may be closed by covers (not shewn)
fitted to them which can be locked to the Pump when not in use, or a conical plug
(R Fig. 1.) having an aperture through its vertical centre may be fitted into them
which serves for holding in position the metal-tube S which can be moved up and
down in the said plug and fixed thereto by a thumbscrew.
In the drawing Fig. 1. the aperture T is thus shewn covered by the perforated
disc W and the aperture U has the plug R inserted into it serving as support to the
metal-tube S which reaches to the bottom of the tank; its lower end being serrated
for the passage of liquid. A length of hose V is connected by screw-couplings P & O
to the upper end of the tube S and to the pumpmouth L the pumpmouths K & M
are closed by screwcaps whilst the mouth N is open.
Supposing the tank Q to contain liquid and the wheel G to be turned in the
direction of the arrow g¹, the liquid contained in the tank Q will be drawn up into
the pump and passing round between the teeth of the wheels G & F will be expelled
from the pump through the aperture D and flow from the outlet N into any vessel
placed underneath it and any overflow or droppings falling upon the top of the tank
will return into the tank through the central opening T and the perforated plate W
placed over it. But by attaching suitable hose to the mouths N or M, as may be
most convenient (the mouth not used being closed by the screwcap) the liquid may
be guided to any tank cask or vessel placed at a distance from the Pumping Appa-
ratus illustrated in Fig. 1. Likewise if what in this case are the inlets L & K are
connected by hose with some other tank cask or vessel containing liquid at a distance
from the apparatus instead of with the tank Q the liquid will be drawn from such
tank cask or vessel instead of from the tank Q
The cone of the plug R is provided with a screwthread and is constructed in this
form so that it may be inserted together with the tube S into the bunghole of a cask
and fixed therein by a turn or two of the. screw whereby the tube S is held in
position reaching to. the bottom of the cask, and the cask may be either filled or
emptied by these means when connected with the pump.
When the wheel F is turned in the direction of the arrow f1 the flow of liquid
through the Pump takes the reverse direction, the opening D is made the inlet and
C the outlet and it will thus be clear that if a tank or vessel say No 1 containing
liquid is connected with D and another No 2 is connected with C if the wheel G be
turned by the winch the liquid will flow from tank No 2 through the pump into
tank No 1 and the opposite will take place when the wheel F is turned by the
winch.
E is a cup and tap inserted into the pump case A by which the interior of the
pump can be lubricated,
E is an outlet closed or opened by a tap by means of which the portion of the
pump case below the level of the openings D & C can be emptied of liquid when
required.
The second part of my invention relates to an arrangement of valve in pumps
constructed according to my herein before described improvements which said valve
arrangement may also be applied to Rotary pumps of ordinary construction. It
also relates to means or apparatus whereby my improved or other form of Rotary
pump may be more readily attached to barrels or tanks for holding mineral or other
oils or liquids, more particularly for the vessel commercially known as Richters
Economiser for which letters patent dated the 25th day of August 1880 and
numbered 3449 were granted in lieu of the pumps hitherto used in the said vessel;
The said improvements consist firstly in fitting the lower end of the suction
pipe of a Rotary Barrel pump with a metal valve which allows the liquid on the
pump being worked, freely to enter the suction pipe, but not to flow therefrom on
the pump being stopped; the valve is arranged in such a manner and position, that
it can be lifted up and opened by the operator applying one of his fingers thereto
by which means the pump and suction pipe are emptied of liquid when desired;
The advantage attained by the use of the valve is to keep the pump and suction

page_text: pipe filled with liquid when desired, whereby a ready and immediate flow from the
pump is obtained as soon as its handle is turned instead of several revolutions being
necessary for the purpose of drawing up the liquid and before the same will begin
flowing from the discharge pipe of the pump.
The necessity for an occasional priming is also diminished in consequence of the
pump being kept lubricated. The pump is mounted in the Economiser or other
vessel by means of a conical plug provided with a collar; the plug is pierced
lengthways by an aperture through its centre through which the suction-pipe of
the pump is passed. The collar of the plug fits into a corresponding aperture in
the top of the tank and can be fastened therein by screws. The pump is thereby
held in a vertical position in the tank, the suction-pipe resting on the bottoni
thereof and being fastened to the plug by a thumbscrew.
The pump together with the conical plug can be lifted out of the tank after the
screws fastening the plug to the top of the tank have been removed, and inserted
in the bunghole of a cask, in which case the conical plug which has a screwthread
running down the outside of its cone, can be screwed fast in the bunghole holding
the pump firmly in position. The pump may then be used as an ordinary Barrel
pump for filling the Economiser or any other vessel, and hose may be attached to
its outflow opening for the purpose of delivering the liquid at a distance.
The pump can also be made reversible in the same manner as the pump described
in the first part of my invention but in that case the metal valve at the end of the
suction-pipe as before-mentioned must be dispensed with, as it acts only one way
and would therefore impede the flow of the liquid in the opposite direction.

page_text: I, GUSTAVUS ADOLPHUS JOHN SCHOTT Manufacturer, of West End Mills
Richmond Road, Bradford in the county of York do hereby declare the nature
of my invention for IMPROVEMENTS IN PUMPING APPARATUS USED FOR TRANS-
FERRING OILS AND OTHER LIQUIDS FROM ONE VESSEL TO ANOTHER and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
The first part of my Invention consists of an apparatus, the main features of
which are illustrated by the accompanying Drawing Fig 1 which represents a
vertical section through the centre of my apparatus, I wish it however to be under-
stood that I do not confine myself to the precise details shewn, as they are susceptible
of variation. A is a Rotary Reversible Pump standing upright, provided with the
openings, C & D and containing the toothed wheels F & G, which gear with each
other and are fixed on and revolving with the axles I & H; either of these axles
may be turned by means of a winch or other mechanism fixed on one end of it
which projects from the interior of the case A, when the wheel mounted on such
axle revolves with it and gearing into the other wheel, imparts a rotary motion to
the latter also. According, as one or other of the axles I & H is turned by means
of the winch, one of the openings D & C will be the Inlet and the other the Outlet
of the Pump. Into these openings the hollow spouts or arms D¹ & C¹ are screwed,
cach of which forks into two mouths M N & KL, all provided with screwthreads,
so that hose can be attached to them by means of a screwcoupling, or they can be
closed by screwcaps when not required.
The Pump is mounted on the stand B, which is fixed upon the centre of the
top X of the rectangular tank Q, which in order to be more readily movable from
place to place may be mounted on wheels. The tank Q thus serves as a stand or
pedestal to the pump, which might however also be mounted on an ordinary bench,
or other stand, but the tank serves some further uses, which render it preferrable
to a stand or support, which serves no other purpose but that of a support. The
two side portions of the top X are each surrounded by a raised rim, and sloping
towards a central opening (T & U) in the manner indicated in the Drawing, over
which the mouths N & L of the Pump are placed at a convenient distance to
admit of vessels being placed on the top X and under these mouths.
The central openings T & U are so arranged that perforated metal discs (see W
Fig. 1) may be placed over them or they may be closed by covers (not shewn) fitted
to them, which can be locked to the Pump when not in use or a conical plug
(R Fig. 1) having an aperture through its vertical centre may be fitted into them,
which serves for holding in position the metal tube S. which can be moved up and
down in the said plug and fixed thereto by a thumbscrew,
In the Drawing Fig. 1 the aperture T is thus shewn covered by the perforated
dise W and the aperture U has the plug R inserted into it, serving as support to

page_text: the metal tube S. which reaches to the bottom of the tank, its lower end being
serrated for the passage of liquid.
A length of hose V is connected by screw couplings P & O to the upper end of
the tube S and to the Pumpmouth L, the Pumpmouths K & M are closed by screw>
caps whilst the mouth N is open.
Supposing the tank Q to contain liquid and the wheel G to be turned in the
direction of the arrow g', the liquid contained in the tank Q will be drawn up into
the pump and passing round between the teeth of the wheels G & F, will be
expelled from the pump through the aperture D and flow from the outlet N into
any vessel placed under it and any overflow or droppings falling upon the top of
the tank, will return into the tank through the central opening T and the perforated
plate W placed over it. But by attaching suitable hose to the mouths Ñ or. M, as
may be most convenient (the mouth not used being closed by the screw cap) the
liquid may be guided to any tank cask or vessel placed at a distance from the
pumping apparatus illustrated in Fig. 1. Likewise if what in this case are the
inlets L or K are connected by hose with some other tank, cask, or vessel containing
liquid at a distance from the apparatus, instead of with the tank Q, the liquid will
be drawn from such tank, cask or vessel instead of from the tank Q.
The cone of the plug R is provided with a screwthread and is constructed in
this form, so that it may be inserted together with the tube S into the bunghole of
a cask and fixed therein by a turn or two of the screw, whereby the tube S is
held in position, reaching to the bottom of the cask, and the cask may be either
filled or emptied by these means when connected with the pump.
When the wheel F is turned in the direction of the arrow F¹ the flow of liquid
through the pump takes the reverse direction, the opening D is made the inlet,
and the outlet and it will thus be clear, that if a tank or vessel say No 1,
containing liquid, is connected with D, and another No 2. is connected with Ĕ, if the
wheel G is turned by the winch, the liquid will flow from tank No 2 through the
pump into tank No 1, and the opposite will take place when the wheel F is turned
by the winch.
E is a cup & tap inserted into the pump case A by which the interior of the
pump can be lubricated.
E is an outlet closed or opened by a tap, by means of which the portion of the
pump case below the level of the openings D & C can be emptied of liquid when
required.
Fig. 2 represents a simplified arrangement of the apparatus, in which a number
of the minor parts are left out, or simpler forms are substituted for them, those
parts common to both constructions are enumerated below and in so far as they
are visible, are indicated by the same letters, whilst the altered parts are indicated
by figures.
The apparatus illustrated by Fig. 2 is less costly in construction, but of course
can only serve that portion of the purposes to which the apparatus Fig. 1 can be put,
for which the corresponding parts have been retained in the simplified construction.
The following are the parts which have been retained in both arrangements,
some being slightly altered in form for convenience of construction.
Upright pump A, Stand B, Openings C & D Oil cup & taps E & E¹, toothed
wheels F & G, Axles H & I, Hose couplings O & P, Hose V Tube S. for
Arms C & D and mouths K. L. M & N Fig. 1 have been substituted, two
ordinary Hose couplings (see 1 Fig. 2) of the same kind as O & P. Fig. 1; the
place of the tank Q,Fig. 1. together with its minor fittings RTU W & X has
been taken by the woodstand 2. Fig 2.
The toothed wheels 3 & 4 & Shaft 5 Fig. 2, upon the end of which the driving
wheel 6 is mounted, are an ordinary arrangement for increasing the leverage and
power for turning the Pump axle H, in cases where the liquid has to be forced
to à considerable height or distance.
When this extra leverage is not required, the shaft 5 can be pulled back, after
loosening the Bolt & nut 7, whereby the toothed wheels 3 & 4 are thrown out of

page_text: gear, and the driving wheel 6 is then taken off the shaft 5, and placed upon the
Pump axle H or I, which are then actuated in the same manner as described in
connection with fig. 1. Of course the whole arrangement for gaining leverage,
consisting of the toothed wheels 3 & 4 and driving shaft: 5 together with its
support and bolt and nut 7 for holding it in position, may also be left away
altogether in cases, where it is not likely to be of use.
The second part of my Invention relates to Improvements in what are known as
Rotary Barrel Pumps, and to adapting the said Pumps for the additional purpose
of being used for tanks, more particularly for the vessel comercially known as
Richter's Economiser, for which Letters Patent dated the 25th day of August 1880
and numbered 3449 were granted, in lieu of the pumps hitherto used in the said
vessel.
The said improved Pump may however also be applied to other vessels used for
holding mineral and other Oils and liquids.
The said improvements consist firstly in fitting the the lower end of the suction
pipe of a Rotary Barrel Pump. with a metal valve which allows the liquid, on the
pump being worked freely to enter the suction pipe, but not to flow out therefrom
on the pump being stopped; the valve is arranged in such a manner and position,
that it can be lifted up and opened by the operator applying one of his fingers
thereto, by which means the pump and suction pipe are emptied of liquid when
desired. The advantage attained by the use of the valve is to keep the pump and
suction pipe filled with liquid when desired, whereby a ready and immediate flow
from the pump is obtained as soon as its handle is turned, instead of several
revolutions being necessary for the purpose of drawing up the liquid and before
the same will begin flowing from the discharge pipe of the pump.
The necessity for an occasional priming is also diminished in consequence of the
pump being kept lubricated.
Fig. 3 is a vertical section of this valve to illustrate its construction, (a) is the
valve cup which is screwed on to the end of the suction pipe of the pump; (b) is
a bridge for carrying the valve (c), which is connected to the bridge by the vertical
valve spindle (d); the latter is provided with a button at its lower end, to prevent
the valve being lifted up too high.
The pump is mounted in the Economiser or other vessel as illustrated in Fig. 4,
by means of a conical plug (a) provided with a collar (b), the plug is pierced
lengthways by an aperture through its centre, through which the suction pipe (c)
of the pump is passed.
The collar of the plug fits into a corresponding aperture (d) in the top of the
tank and can be fastened therein by screws (e & f). The pump is thereby held in
a vertical position in the tank, the suction pipe resting on the bottom thereof and
being fastened to the plug by a thumbscrew (g)..
The pump together with the conical plug (a) can be lifted out of the tank, after
the screws (e & f), fastening the plug to the top of the tank, have been removed,
and inserted in the bunghole of a cask, in which case the conical plug, which has
a screwthread (h) running down the outside of its cone can be screwed fast in the
bunghole, holding the pump firmly in position. The pump may than be used as
an ordinary Barrel pump for filling the Economiser or any other vessel, and hose
may be attached to its outflow opening for the purpose of delivering the liquid at
a distance.
The pump can also be made reversible in the same manner as the pump described
in the first part of my invention, but in that case the metal valve at the end of
the suction pipe as before mentioned and illustrated in Fig. 3 must be dispensed
with, as it acts only one way and would therefore impede the flow of the liquid in
the opposite direction.
I would have it understood however, that I do not confine myself to the precise
mechanical details of construction as herein before specified as such details admit
