PROVISIONAL SPECIFICATION.
An Improved Apparatus for Facilitating the Transfer of Oil or other
Liquids from one Vessel to another.
I, JOHN CHARLES MEYERS, of 106 Rathgar Road, in the County of Dublin, Ireland,
General Merchant, do hereby declare the nature of this invention to be as follows:-
This invention has reference to an new or improved apparatus for facilitating the
transfer of oil, or other liquids from one vessel to another and is especially designed
for charging or supplying oil to lamps for domestic or other purposes in a convenient,
safe, and simple manner, and without waste of the liquid.
The construction and action of my invention will be readily understood on
reference to the accompanying drawings.
Fig. 1 is an elevation and Fig. 2 a vertical cross-section of the apparatus complete.
A, is a cylinder, or other suitable shaped vessel closed at both ends. The top is
slightly recessed and dished towards the centre and is provided with an aperture,
through which the pump device is inserted. This pump device consists of an outer
tube b, provided at the top with a dished flange e to which is attached an india
rubber or other flexible cap d, and is provided at its lower end with an aperture in
which rests a marble e, as shown. Within this tube is arranged an inner tube f,
having an exit at the top to which is attached the flexible tube g.
In the lower end of this tube is an expanded chamber h, containing a marble i, and
aperture as shown. An outer case k, is arranged around the upper portion of the
pump in which are pierced the apertures 1, 1 for the purpose of admitting air to the
cylinder or receptacle.
Now the action of the apparatus is briefly as follows.
The cylinder, or receptacle having been filled through the aperture in which rests
the pump, the end of the flexible tube f, is introduced to the lamp or other vessel to
be charged whereupon the india rubber capd, is pressed down and on its re-expansion
the marble e, at the hottom of the tube is drawn from its seat and a certain quantity
of liquid enters and rises in the annular space between the outer and inner tubes.
Upon the next pressure of the india rubber cap the marble e, is driven to its normal
seat, while the marble i, is driven from its seat and the liquid in the annular space
between the outer and inner tubes, caused to mount the inner tube, and flow through
the flexible tube g.
The india rubber cap is again pressed, and the same result is repeated so long as it
is desired to continue the flow of liquid.

COMPLETE SPECIFICATION.
An Improved Apparatus for Facilitating the Transfer of Oil or other
Liquids from one Vessel to another.
I, JOHN CHARLES MEYERS, of 106 Rathgar Road, in the County of Dublin,
Ireland, General Merchant, 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 reference to a new or improved apparatus for facilitating the
transfer of oil or other liquids from one vessel to another, and is especially designed

page_text: for charging or supplying oil to lamps for domestic or other purposes in a convenient,
safe, and simple manner.
The nature, construction, and operation of my invention will be readily understood
on reference to the accompanying drawings.
Fig. 1, is an elevation, and Fig. 2, a vertical section of the apparatus per se, and
Figs. 3, and 4, show examples of its application as hereinafter more fully described.
In my Provisional Specification I described the apparatus in combination with a
cylindrical vassel in a general way; I now prefer to describe the apparatus which
constitutes the essential feature of my invention in the first instance, and afterwards
its application and operation.
In the several figures b, is an outer tube provided at the top with n dished flange c,
to which is attached an india-rubber or other flexible cap d. This cap is hold securely
in position by a ring d', which is first placed in the cap before the latter is pressed
into the dished flange. By this means the cap can be readily removed, or ronewed
when required.
In the lower end of the tube is an aperture closed by a marblo e, as shown.
Within this tubo, is arranged an inner tube provided with an exit pipo g, at the
top, to which may be attached a flexible tube when required. At the lower end
of this tube is an elongated chamber, in the bottom of which is an aperture closed by
a marble i, as in the case of the outer tube. A casing k, is placed around the upper
portion of the outer tube for strengthening purposes.
The lines shown at s, and t, indicate cross wires in the tubes to provent the marbles
rising unnecessarily high.
As thus constructed the apparatus may be introduced to any vessel from which it
is desired to draw off liquids, and its action is as follows.
Upon pressing the indin-rubber cap an impulse of air will pass down the annular
spaco, and escape through the inner tube by lifting the marble i, which will
immediately resume its sent. As the cap re-expands, the liquid in the vessel will bo
caused by suction to rush through the valve e, rising in the annular space, until the
next pressure of the cap, which acting on the liquid thus recoived in the annular
space, causes it to ascend the inner tube through the valve i, (it cannot return to the
vessel owing to the closing of the valve e, meantimo) and escape through the exit pipe.
On the second re-expansion of the cap the operation is repeated, and thus the flow
of liquid is maintained.
Fig. 3, represents the application of the apparatus to an ordinary cistern, for
example a domestic oil vessel, as illustrated in my Provisional Specification.
The top of the vessel is slightly inclined towards the centre, and the apparatus may
be turned half round so as to enable drops which may fall from the exit pipe to return
to the cistern through the filling aperture 1.
Fig. 4, shows the apparatus in combination with a device for measuring purposes.
Between the exit pipe g, and an arm g', is mounted a glass cylinder which is
graduated according to pleasure, and is provided at its lower and with an ordinary
бар.
By this arrangement certain quantities of liquid can be pumped into and measured
in the cylinder, whereupon an empty vessel is applied to the tap, and the measured
quantity thus drained off.
The pump apparatus in this case may also be turned half round as indicated in
dotted lines, so as to allow drops to return to the original vessel, and thus obviate
waste or dropping of liquids on the floor.
It is obvious that my invention may be used on the syphon principle whon dis
charging liquid from one vessel to another at a lower level. For this purpose it is
only necessary to prolong the length of the exit pipe, by the addition of a flexible or
other tube, and once the current is established in the manner above described the
liquid will flow continuously. To arrost the flow, air may be admitted through a
suitable valve formed in the exit pipe. In this respect the apparatus may be used
with advantage for discharging casks, barrels, and such like vessels.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1st. The use and application of an apparatus for the purpose of facilitating the
transfer of liquids, from one vessel to another, constructed, arranged, and operated as
herein described and illustrated.
2nd. The use and application of a measuring cylinder as described and illustrated
in Fig. 4, in combination with the pumping apparatus, in the manner herein described
and set forth.
