Improvements in the Construction of Vessels for Holding, Distri-
buting, and, if desired, Straining or Filtering Cylinder Oil or
other Oils or Liquids.
I, GUSTAVUS ADOLPHUS JOIN SCHOTT, of No. 48, Richmond Road, Bradford,
in the County of York, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates more particularly to improvements in vessels for holding
and distributing thick oils and liquids of a viscous nature, such as cylinder oil,
varnish and the like, but the said vessels may also be used for ordinary thin
liquids, and they may be constructed with arrangements for straining or filtering
the liquids. If thick liquids are withdrawn from holders by a tap the process
is very slow and otherwise unsatisfactory: if a piston pump is used the valves
of the pump cannot work freely in the thick liquid and are liable to be clogged;
if an ordinary rotary pump provided with a suction pipe is inserted into the
vessel, the liquid on account of its viscosity ascends the suction pipe with difficulty
and only when a comparatively perfect vacuum is created, and the work of
passing the liquid through the pump is correspondingly uncertain and heavy.
To obviate these difficulties I place a rotary pump of an ordinary construction
at the bottom of the vessel in such a position that the turning axle of the pump
stands upright vertically. The turning axle I elongate by attaching to it a
vertical rod, which I term the pumprod, and which reaches upwards to above
the top or well of the vessel, where it bears one of a pair of bevel wheels, the
corresponding wheel being mounted on one end of a horizontal shaft, which
projects over the outer rim of the vessel and is turned by hand by means of a
handle permanently or temporarily fixed on its free outer end.
By these mechanical arrangements I gain the power necessary for overcoming
the resistance of the viscous liquid and turning the pump and forcing the liquid
through it and the outflow pipe with comparative case. The outflow pipe is
connected to the outlet of the pump and proceeds upwards to a convenient height
above the top or well of the vessel, where the liquid is discharged into any can
or vessel placed under the outflow aperture. As the pump is placed at the bottom
of the vessel as beforementioned, the liquid has not to ascend to reach the pump,
but flows partly by its own gravity, partly by the sucking action of the pump,
when turned, into the inlet of the pump. This arrangement I find to answer
satisfactorily in the case of cylinder oils and similar liquids, but it is not
sufficient for varnish, because this liquid, besides being viscous, has the property
of hardening by exposure to the atmosphere and forming a skin at its surface,
where exposed to the air, whereby the delivery pipe, unless kept continually filled
with liquid in all its parts, which is impracticable, is gradually made up, so that
the liquid cannot freely and in sufficient quantity pass through it. To overcome
this further difficulty I construct the delivery pipe of a larger diameter, than
what would otherwise be necessary, and mount the pump rod before mentioned,

page_text: inside the delivery pipe, the whole interior space of which must however not be
occupied by the said pumprod, but only the centre, as there must be also room
for the liquid to pass up the delivery pipe at the top of which an outflow is con-
veniently arranged of such form that it can be conveniently cleaned. On the
pump rod I arrange or fix suitably wings of flat or sheet iron or other material,
which without obstructing the passage of the liquid up the delivery pipe scrape
the interior surface of the pipe when the pump rod is turned and thus prevent
the formation of a skin or deposit of hardened varnish on the interior surface of
the delivery pipe to a sufficient degree to leave a passage open for the liquid
varnish. The pump rod 1 arange to pass out of the delivery pipe through a
stuffing box which closes the top of the delivery pipe, and the outflow I may
provide with a suitable tap so that the air is sufficiently excluded from the
interior of the delivery pipe, when the aparatus is not being worked.
When the apparatus is to be used for filtering it is advisable to take the
delivery pipe of a still larger diameter than in the case of varnish, so as to obtain
a good filtering surface.
The filter is formed of one or more layers of cotton waste or other filtering
materials suitably compressed by springs or screwing between two circular metal
sieves of a diameter corresponding to the interior diameter of the delivery pipe,
and placed therein in such manner that the liquid must pass through the filtering
material in ascending the delivery pipe. The centre of the filter may be pierced
vertically by a hollow metal tube through which the pump rod passes, so that the
latter, when revolving, cannot disturb the filtering material or process. The
delivery pipe need not necessarily be circular but may be of other shape.
The vessels into which the above described fittings are placed may also vary
in form, size and other details of construction according to requirements.

Improvements in the Construction of Vessels for Holding, Distri-
buting, and, if desired, Straining or Filtering Cylinder Oil or
other Oils or Liquids.
I, GUSTAVUS ADOLPHT'S JOHN SCHOTT, of No. 48, Richmond Road, Bradford,
in the County of York, Manufacturer, 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 vessels for holding
and distributing thick oils and liquids of a viscous nature, such as cylinder oil,
varnish and the like, but the said vessels may also be used for ordinary thin
liquids, and they may be constructed with arrangements for straining or filtering
the liquids. If thick liquids are withdrawn from holders by a tap the process
is very slow and otherwise unsatisfactory; if a piston-pump is used the valves
of the pump cannot work freely in the thick liquid and are liable to be clogged ;
if an ordinary rotary-pump provided with a suction pipe is inserted into the
vessel, the liquid on account of its viscosity ascends the suction pipe with
difficulty and only when a comparatively perfect vacuum is created, and the work
of passing the liquid through the pump is correspondingley uncertain and
heary.
To obviate these difficulties I have devised the arangement illustrated in Fig. 1.
I place a rotary pump A" of an ordinary construction at the bottom of the
$6

page_text: vessel "B" in such a position that the turning axle "C" of the pump stands
upright vertically. The turning axle I elongate by attaching to it a vertical
rod "D," which I term the pumprod, and which reaches upwards to above the
top or well "E" of the vessel "B," where it bears one of a pair of bevel
wheels "F & "," the corresponding wheel being mounted on one end of a
horizontal shaft "G," which projects over the outer rim of the vessel and is
turned by hand by means of a handle "H," permanently or temporarily fixed on
its free outer end.
By these mechanical arrangements I gain the power necessary for overcoming
the resistance of the viscous liquid and turning the pump and forcing the liquid
through it and the outflow pipe with comparative ease. The outflow pipe "I"
is connected to the outlet of the pump and proceeds upwards to a convenient
height above the top or well of the vessel, where the liquid is discharged into
any can or vessel placed under the outflow aperture. As the pump is placed at
the bottom of the vessel as before mentioned, the liquid has not to ascend to
reach the pump, but flows partly by is own gravity, partly by the sucking action
of the pump, when turneu, into the inlet of the pump. This arrangement I find to
answer satisfactorily in the case of cylinder oils and similar liquids, but it is not
sufficient for varnish, because this liquid, besides being viscous, has the property
of hardening by exposure to the atmosphere and forming a skin at its surface,
where exposed to the air, whereby the delivery pipe, unless kept continually filled
with liquid in all its parts, which is impracticable, is gradually made up, so that
the liquid cannot freely and in sufficient quantity pass through it. To overcome
this further difficulty I have devised the apparatus illustrated in Fig. 2. I con-
struct the delivery pipe "I" of a larger diameter, than what would otherwise be
necessary, and mount the pump rod "K" inside the delivery pipe "I," the whole
interior space of which must however not be occupied by the said pumprod, but
only the centre, as there must be also room for the liquid to pass up the delivery
pipe, at the top of which an outflow "L" is conveniently arranged of such form
that it can be conveniently cleaned. On the pump rod "K" I arrange or fix
suitably wings "M" of Hat or sheet iron or other material, which, without
obstructing the passage of the liquid up the delivery pipe "I," scrape the interior
surface of the said pipe when the pumprod is turned and thus prevent the forma-
tion of a skin or deposit of hardened varnish on the interior surface of the
delivery pipe to a sufficient degree to leave a passage open for the liquid varnish.
The pumprod "K" I arrange to pass out of the delivery pipe "I" through a
stuffing box "N," which closes the top of the delivery pipe, and the outflow"L"
I may provide with a suitable stopper so that the air is sufficiently excluded
from the interior of the delivery pipe "I," when the apparatus is not being
worked.

In Figure 3, is illustrated the connection of the delivery pipe "I" with the
rotary pump A," of which "a" is the turning axle to which the pump-
rod "K' is attached. Buth a" and "K" are enclosed in the delivery
pipe "I" which is connected by male and female screw threads to the stuffing
box "a" of the pump. To the outlet, of the pump is attached a tee a5" which
communicates by a short pipe "a" with a square "a" which latter is attached
to the inlet of the delivery pipe "I." The liquid therefore passes from the pump
through a5," a³," " and "a" into the delivery pipe "I," which it ascends as
before mentioned. a¹, 2 & 3" are screw plugs which can be removed for the
purpose of giving access to the interior of "a³, 8 & 8" for cleaning purposes.

In Figure 4 is illustrated the construction of a tank of the kind illustrated in
Fig. 1, but arranged for filtering or straining the oil, and fitted for the special
purpose of serving in the continuous lubrication of the shafts and bearings of
steam engines, dynamos and the like. The same letters of reference in Figs. 1 & 4
denote analogous parts, which however are somewhat divergent in form and
details in the two constructions. I will now describe the manner in which the

page_text: lubricating tank illustrated in Fig. 4 is used and in doing so give a description
of its component parts. On the norizontal driving shaft "G," being turned by
means of the pulley "O" and a driving belt placed thereon, the bevel wheel "F1"
fixed on the shaft "G" turns the vertical shaft "D" upon which the corre-
sponding bevel wheel "F" is fixed, and thereby the rotary pump "A," to the
outlet of which is connected the delivery pipe "P", which proceeds outside the
tank "B" and branches off to the various shafts and bearings, over which it
discharges the lubricant. The latter after running over the said shafts and
bearings is caught and collected in dripping pans placed under the said shafts
and bearings and conducted back by pipes to the tank "B", which it re-enters
through the discharge pipe or pipes "Q", of which there may be one or more.
"R" is a perforated tin pan with comparatively few & small perforations, which
serves to spread the oil flowing from "Q" as evenly as possible over a larger
area. Underneath the spreader "R" are placed one or more filtering sieves "S",
upon which cotton waste or other suitable filtering material is placed and the
function of which is to clean and filter the oil on percolating through them,
after which the purified oil collects at the bottom of the tank "B" and is avail-
able for further circulation and lubrication. The discharge pipes "Q" as shown
in Fig. 4 are capable of being turned up into a vertical position by being provided
with the swivel joints "9", so that the sieves "S" and spreader 'R'
" can be
lifted out of the tank, when they require to be cleaned and provided with fresh
filtering material. A lid "T" serves to cover in the tank "13" and its contents.
The vessels into which the above described fittings are placed may vary in
form, size and other details of construction according to requirements.
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 tank or oil holder with a handle "H" horizontal shaft "G", pair
of bevel wheels "F", and vertical shaft "1", for the purpose of working a
rotary pump "A" placed at the bottom of the tank, substantially as herein before
set forth and shown in Fig. 1.
2) Fitting a tank or holder for varnish and similar liquids, in which a rotary
pump placed at the bottom of the tank is used for discharging the said liquids,
with a delivery pipe "I" which encases the pump rod "K" the said pump rod
being fitted with wings or scrapers "M" for the purpose of keeping a way open
through the said delivery pipe for the liquid to flow through substantially as
described and shewn in in Fig. 2.

3.) The combination in a lubricating tank "B" of a horizontal driving
shaft "G", pulley "0", pair of bevel wheels "F", vertical shaft "D", rotary
pump delivery pipe "P", return pipe or pipes "Q", spreader "R", and
filtering sieves or strainers "S", substantially as and for the purposes herein
before set forth, and shewn in Fig. 4.
