Improvements in Lubricators.
WILLIAM BOBY of 16, Union Court, Old Broad Street, London, E.C., Engineer
and HENRY WHITE BOWDEN of 46 Werter Road, Putney, Engineer do hereby
declare the nature of this invention to be as follows:-
Our invention relates to an improved arrangement of the parts of lubricators
such as are used for lubricating the bearings and external moving parts of engines
and machinery, and its objects relate principally to the maintaining of the adjusting
screws which regulate the flow of the oil, in the position into which they may be
turned by the attendant so that such position shall not be changed by the vibration
of the machinery; and to the provision of a means of stirring or disturbing the
oil so that any thicker part of the oil which may tend to settle at the bottom of
the lubricator will be from time to time moved & distributed amongst the oil in
the lubricator and the fresh oil as it is filled into the lubricator. The lubricator
is constructed of any convenient form usually rectangular having a lid and may be
provided with a number of regulating screws each of which consists of a nozzle or
socket held to the bottom or side of the lubricator by a nut or other device, and
communicating with the inside, or it may be placed inside the lubricator. The
bore of the nozzle is tapered & into it fits a spindle the end of which is tapered
to suit the bore of the nozzle. Above its tapered end the spindle has a screw cut
upon it, and the spindle is continued to a convenient height and provided with a
suitable head or wheel for enabling the attendant to turn it. On the upper side
of the nozzle is formed a tube with two or more longitudinal slots in it on the top
of the tube is formed a nut which fits the screw upon the spindle of the regulating
screw. The outside of the nut is preferably cylindrical with a flange or projection
at each end. The nut is divided into two or more portions preferably being cut
by a fine saw. On the outside of the nut is placed a spiral spring, the normal
inside diameter of the coil of which is less than the outside diameter of the nut
and compresses it so that it grasps the screw of the spindle and prevents it from
turning from the effects of vibration. The oil as it drops from the end of the
spindle falls into a small funnel provided with a strainer of fine wire gauze and
from thence it is conducted by a tube or any convenient method to the part to be
lubricated.
In the lubricator is placed a tray extending nearly its whole length and width
pivotted at a point preferably not in the centre of its length and preferably at its
fonger end having a rod pivotted to it which passes through the lid of the lubricator
and is attached at its upper end to a lid which covers the hole in the lid of the
lubricator through which it is filled with oil. The rod is guided so that the lid
may always shut in the proper position for covering the hole. The tray is made
preferably of such a form that when the lid of the lubricator is closed and the
fonger end of the tray is in its lowest position a considerable portion of the tray
lies along the bottom of the lubricator, when it is raised for opening the lid of the
filling hole it lifts a quantity of the oil from the bottom of the lubricator and
causes it to run to the other end of the lubricator disturbing and mixing it by so
doing. Similarly when the lid of the filling hole is again closed the oil will be
disturbed and mixed. The oil can at any time be agitated, and mixed by the
attendant operating the tray but its agitation is a matter of necessity and cannot
fail to be effected when filling the lubricator. The attachments of the tray are
preferably connected to the lid of the lubricator so that no holes for this purpose

cause leakage.

Improvements in Lubricators.
WILLIAM BOBY of 16 Union Court, Old Broad Street London E.C. Engineer
and HENRY WHITE BOWDEN of 46 Werter Road Putney Engineer 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 ---
Our invention relates to an improved arrangement of the parts of lubricators
such as are used for lubricating the bearings and external moving parts of engines
and machinery and its objects relate principally to the maintaining of the adjusting
screws which regulate the flow of the oil in the position into which they may be
turned by the attendant so that such position shall not be changed by the vibration
of the machinery; and to the provision of a means of stirring or disturbing the
oil so that any thicker part of the oil which may tend to settle at the bottom of
the lubricator will be from time to time moved and distributed amongst the oil in
the lubricator, and the fresh oil as it is filled into the lubricator. The lubricator
may be constructed of any convenient form usually rectangular having a lid and
may be provided with a number of regulating screws each of which may consist of
a nozzle or socket held to the bottom or side of the lubricator by a nut or other
device and communicating with the inside or it may be placed inside the lubricator.
The bore of the nozzle is tapered and into it fits a spindle the end of which is
tapered to suit the bore of the nozzle. Above its tapered end the spindle has a
screw cut upon it, and the spindle is continued to a convenient height and provided
with a suitable head or wheel for enabling the attendant to turn it. On the upper
side of the nozzle, or separately from the nozzle and fixed to any convenient part
of the lubricator is formed a tube with two or more longitudinal slots in it, on
the top of the tube is formed a nut which fits the screw upon the spindle of the
regulating screw.
The outside of the nut is preferably cylindrical with a flange or projection at
each end. The nut is divided into two or more portions preferably being cut by a
fine saw.
On the outside of the nut is placed a spiral spring the normal inside
diameter of the coil of which is less than the outside diameter of the nut and
compresses it so that it grasps the screw of the spindle and prevents it from
turning from the effects of vibration. The oil drops visibly from the end of the
spindle and falls into a small funnell provided with a strainer of fine wire gauze
and from thence it is conducted by a tube or any convenient method to the part
to be lubricated. In the lubricator is placed a tray extending nearly its whole
length and width pivotted at a point preferably not in the centre of its length and
preferably at its longer end having a rod pivotted to it which passes through the
lid of the lubricator and is attached at its upper end to a lid which covers the
hole in the lid of the lubricator through which it is filled with oil.
The rod is guided so that the lid may always shut in the proper position for
covering the hole.
The tray is made preferably of such a form that when the lid of the lubricator
is closed and the longer end of the tray is in its lowest position a considerable
portion of the tray lies along the bottom of the lubricator, when it is raised for
opening the lid of the filling hole it lifts a quantity of the oil from the bottom of
the lubricator and causes it to run to the other end of the lubricator disturbing
and mixing it by so doing.

page_text: Similarly when the lid of the filling hole is again closed the oil will be
disturbed and mixed. The oil can at any time be agitated and mixed by the
attendant operating the tray but its agitation is a matter of necessity and cannot
fail to be effected when filling the lubricator. The attachments of the tray are
preferably connected to the lid of the lubricator so that no holes for this purpose
are made in the sides or bottom of the lubricator where they might be liable to
cause leakage. The tray may be moved by any suitable moving part of the
machinery to which the lubricator is attached by means of a lever connecting rod
or other suitable connection.
