Improvements in or in the Construction of Sight Feed Lubricators
for Gas Exhausters or other purposes.
We, THOMAS JOHN BASS of 95 Albion Street, Rotherhithe in the County of
London, Engineer, and GEORGE FREDERICK SKUDDER of Holly Lodge,
Lewisham, Mill Furnisher, do hereby declare the nature of this invention to be
as follows:-
This invention relates to sight feed lubricators for gas exhausters or for feeding
oil in other cases either under pressure or vacuum such as compressed air engines
gas and oil engines etc. or same may be used as an ordinary sight feed lubricator
i.e. where neither vacuum nor pressure have to be considered.
The present invention is as follows :-
The usual or any suitable connection to the part to be lubricated contains a
passage or separate communication leading to above the top of the oil in the oil
reservoir which latter may be of any suitable size and shape and the filling orifice
of which is hermetically or sufficiently tightly closed in any well known or suitable
manner.
A regulating stop cock or valve or equivalent serves to close this ascending pipe
or passage when desired for instance when filling the reservoir with oil.
A descending pipe or passage leads from the lower part of said oil reservoir and
terminates in (advantageously within the glass part of) the main connection or
connecting passage leading to the part to be lubricated and in this said descending
pipe or passage a needle or regulating device is arranged to close said passage
very gradually this being advantageously a long tapering or conical needle point
(the lower end of the said pipe being if desired correspondingly internally tapered
or coned) and at its- upper end carries a vertical rack adapted to slide in said
descending pipe or passage the raising and lowering being effected by a pinion on
a shaft or pin which passes through a gland or stuffing box or other packing or
tight fitting to the exterior of the casing or apparatus and terminates in a knob or
other suitable appliance by which same can be revolved to thus raise or lower the
aforesaid needle and thus the feed can be very finely regulated or graduated.
Or the aforesaid needle may be raised and lowered by any mechanical equivalent
or other suitable means instead of the said rack and pinion for instance by
prolonging the needle or shank thereof through the top of the oil reservoir and
having an adjusting nut to screw thereon or by a worm gear etc.
In the lower part of the aforesaid main connection or connecting passage
leading to the part to be lubricated i.e. between the latter and the outlet of the
said regulating passage any suitable spongy or porous or filtering medium or other
suitable material may be used for the purpose of preventing or intercepting
(especially in gas exhausters) tarry or other matter passing up to or depositing on
the glass through which the feed is seen and thus by the present invention the
said glass in such lubricators is kept cleaner or receives less deposit on the inside
than heretofore.
Also this said filtering etc. material (which for instance may be worsted-linen or
muslin or the like stretched on a ring or frame so that same can be easily removed
or replaced or may be worsted waste cotton wool etc. held in a removable wirework

page_text: or openwork cage or receptacle built in to or adapted to fit in said passage) will
serve to arrest any impurities (i.e. filter) the oil as it is fed through same.
In addition to the above-if desired we may also use a device of cylindrical or
other suitable shape adapted to fit or to be fitted within the main casing between
the sight feed and the aforesaid filtering etc. material across the open ends of which
device we stretch or arrange or mount in any suitable manner wire gauze. muslin
or other suitable material to further prevent or reduce deposit on the inside of the
glass.

Improvements in or in the Construction of Sight Feed Lubricators
for Gas Exhausters or other purposes.
We, THOMAS JOHN BASS of 95 Albion Street, Rotherhithe, in the County of
London, Engineer, and GEORGE FREDERICK SKUDDER of Holly Lodge,
Lewisham, Mill Furnisher, 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 to sight feed lubricators for gas exhausters or for feeding
oil for other lubricating purposes either under pressure or vacuum for instance for
compressed air engines gas and oil engines etc. or same may be used as an
ordinary sight feed lubricator i.e. where neither vacuum nor pressure has to be
considered.
The accompanying drawing shows a vertical section of a sight feed lubricator
according to our present invention which we will now proceed to fully describe
with reference to said drawing.
A is the oil reservoir which may be of any suitable size and shape.
B is passage or communication between the top of the oil reservoir and the
lower part of the appliance.
C is closely fitting cap in the filling orifice or the latter may be closed
hermetically or sufficiently tightly in any other suitable manner.
A regulating stop cock or valve D or equivalent serves to close this ascending
pipe or passage B when desired for instance when filling the reservoir A
with oil.
A straight through descending pipe or passage E leads from the lower part of said
oil reservoir A and terminates at E' in (advantageously within the glass part X of)
the main connection or connecting passage leading to the part to be lubricated and in
this said descending pipe or passage E a needle or regulating device is arranged to
close said passage very gradually this being advantageously a long tapering or
conical needle point F1 (the lower end E¹ of the said pipe or passage E being if
desired correspondingly internally tapered or coned for instance as shown at E')
this needle point F1 at its upper end carries a vertical rack F adapted to slide in
said descending pipe or passage E the raising and lowering being effected by a
pinion G on a shaft G₁ which passes through a gland or stuffing box or other
packing or tight fitting (not shown) to the exterior of the casing or apparatus and
terminates in a milled head or other suitable appliance on said shaft G¹ by which
same can be revolved to thus raise or lower the aforesaid needle F¹ and thus the
feed can be very finely regulated or graduated..
Or the aforesaid needle F¹ may be raised and lowered by any mechanical

page_text: equivalent or other suitable means instead of the said rack F and pinion G for
instance by prolonging the needle F' or shank thereof right up through the top of
the oil reservoir A and having an adjusting nut to screw thereon or by a worm
gear etc.
In the lower part Y of the aforesaid main connection or connecting passage
leading through the passage Z-to the part to be lubricated i.e. between the
latter and the outlet E¹ of the said regulating passage E any suitable spongy or
porous or filtering medium H or other suitable material may be used for the
purpose of preventing or intercepting (especially in gas exhausters) tarry or other
matter passing up to and depositing on the inside of the glass X through which
the feed is seen and thus by the present invention the said glass X in such
Jubricators is kept clean of deposit or receives less deposit on the inside than
heretofore.
Also this said filtering etc. material (which for instance may be worsted linen or
muslin or the like stretched on a ring or frame so that same can be easily removed
or replaced or may be worsted waste cotton-wool etc. such as H held in a removable
wirework or openwork cage or receptacle built in to or adapted to fit in said
passage or contained loosely in the part of the main passage) will serve to
arrest any impurities (i.e. filter) the oil as it is fed through same.
In addition to the above-if desired we may also use a device I of cylindrical
or other suitable shape adapted to fit or to be fitted within the main casing
between the sight feed E' and the aforesaid filtering etc. material H across the open
ends of which device I we stretch or arrange or mount in any suitable manner
wire gauze muslin or other suitable material to further prevent or reduce deposit
on the inside of the glass X.
If desired the device I may be formed as a reticulated cage (or have horizontal
reticulated ends thereto) within which a little wool or other absorbent material may
be placed.
The various parts are made of any suitable material or materials and are
constructed or arranged to fit or be fitted together in any suitable manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. In sight feed lubricators for gas exhausters or other purposes-the combination
with the oil reservoir and main passage leading to the part to be lubricated of a
passage or communication such as B between the latter and the top of the oil
reservoir a stop cock or valve such as D to control said passage B a straight
through passage such as E for the oil feed a coned point or needle such as F1
controlling the outlet E¹ of said passage E and means such as the filtering"
medium H or I or both interposed below the glass X in the passage leading to
the part to be lubricated to arrest impurities and prevent tarry or other matter
passing up to the inside of the glass ✗ substantially in the manner and for the
purposes hereinbefore described.
2. The combination with a sight feed lubricator of any suitable construction of
filtering material or medium arranged in the passage leading to the part to be
lubricated and between the latter and the sight feed glass to arrest impurities and
prevent tarry or other matter passing up to the inside of the said glass substantially
as described.
