IMPROVEMENTS IN LUBRICATING JOURNALS OF RAILWAY CARRIAGES
Year: 1885

page_text: I, JOHN MCGILL, Railway Station Ayr, in the county of Ayr, Station Master, do
hereby declare the nature of my invention for "IMPROVEMENTS IN LUBRICATING
JOURNALS OF RAILWAY CARRIAGES" to be as follows:-
A Lubricator made of Iron, Tin, Brass Copper or other metals, and consisting of
two or more compartments communicating by a central pan or box at the bottom.
The side compartments are arranged to allow the journals of axle to revolve
between them. The bottom pan or box is divided horizontally into two com-
partments, the upper being in direct communication with the side compartments.
space is left between the ends of the upper division & the ends of Lubricator,
& this forms a communication between the tray on the top of this upper compart-
ment, and the bottom one, hereafter described. Inside this upper division a small
box or tube is fitted with an opening upwards to supply the pads with oil. The
under compartment extends the whole length of Lubricator & communicates with
the tray on the top of the upper compartment by means of a tube, and by the
spaces left at the ends of the upper pan, which are perforated at the tray. Above
these compartments and between the sides of Lubricator, there is an open tray or
pan, in which the pads to lubricate the journal are placed. These pads which may
be made of any suitable material for distributing oil, are fed from the upper or
feed pan through the before described box, which may be filled with wick to feed
the oil. The pads are kept in constant contact with the journal, by means of
springs attached to the underside of Lubricator. Any superfluous oil, that may be
supplied to the Pads escapes through the holes at the ends of the tray into the
under or overflow pan, already described, from whence it is again fed to the pads,
through the tube, filled with wick, that communicates with the pad tray, thus
preventing waste. The Lubricator is filled through a hole fitted with a screw
stopper, in the top of one or both sides, the end of either or both sides being glass,
to shown readily the amount of oil in Lubricator. A drain hole fitted with a
screw stopper is placed as far down as possible in the end of overflow pan to
enable same to be emptied or cleaned. The space available for holding oil consists
of the sides & upper division of the bottom. The Lubricator is fixed on an iron
frame to the underside of which springs are fitted to adjust it, to the journal, it is
lubricating.

I, JOHN MCGILL Railway Station Ayr, in the County of Ayr, Station Master do
hereby declare the nature of my invention for "IMPROVEMENTS IN LUBRICATING
JOURNALS OF RAILWAY CARRIAGES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
A Lubricator made of Iron, Tin, Brass, Copper or other metals, and consisting of
two or more compartments communicating by a central pan or box at the bottom.
The side compartments are arranged to allow the journal of axle to revolve
between them. The bottom pan or box is divided horizontally into two com-
partments, the upper being in direct communication with the side compartments.
A space is left between the ends of the upper division and the ends of the
Lubricator and this forms a communication between the tray on the top of this
upper compartment and the bottom one hereafter described. Inside this upper
division a small box or tube is fitted with an opening upwards to supply the
pads with oil. The under compartment extends the whole length of Lubricator
and communicates with the tray on the top of the upper compartment by means
of a tube, and by the spaces left at the ends of the upper pan, which are perforated
at the tray. Above these compartments and between the sides of Lubricator there
is an open tray, or pan, in which the pads to lubricate the journal are placed:
These pads which may be made of any suitable material for distributing oil are
fed from the upper or feed pan through the before described box, which may be
filled with wick to feed the oil. The pads are kept in constant contact with the
journal, by means of springs attached to the underside of Lubricator. Any
superfluous oil that may be supplied to the pads escapes through the holes at the
end of tray into the under or overflow pan, already described, from whence it is
again fed to the pads through the tube filled with wick, that communicates with
the pad tray. The Lubricator is filled through a hole fitted with a screw stopper
near the top of one side, the end of one side being fitted with a glass tube to
show readily the amount of oil in Lubricator. A drain hole fitted with a screw
stopper is placed as far down as possible in the end of overflow pan to enable same
to be emptied or cleaned. The space available for holding oil consists of the sides
and upper division of the bottom. The Lubricator is fixed on an iron frame to the
underside of which springs are fitted to adjust it to the journal it is lubricating.
A. A. B, are compartments made to contain the oil for lubricating the journal,
and are all communicating. C is a small box or tube with open end inserted in B
and fitted with wick to feed oil to the pads P, P, in upper tray L which com-
municates with B through the aperture D. E is a second compartiment extending
the whole length of the sides A A. F. F. are holes perforated at ends of.com-
partment E and open to tray L for the purpose of relieving the pads P. P of any
superfluous oil that may be taken into them. This superfluous oil runs into the
box E through the holes F F. From E a tube G is led through B and opens into
tray L. G is fitted with wick to feed oil collected in E back into P, as required.
His a hole fitted with screw stopper in the end of E for cleaning or emptying

page_text: that compartment. A hole I also fitted with screw stopper is placed near
the top of side compartment and through this the Lubricator is filled with oil.
The end of one side is fitted with a glass tube X to show the quantity of oil in
Lubricator. The Lubricator is fixed on an iron frame M and to the underside of
this, springs N, are attached to adjust the Lubricator and pads to the journal of
the axle. The form of the Lubricator is of course modified by the shape of the
box it has to fit, as is shown in the case of the recesses K'K which are required to
enable it to fit a particular box.
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,
1st That the Lubricator will prevent all loss of oil.
2nd That it will keep the oil entirely free from dust.
3rd That it will give a continuous and uniform supply of oil to the journal.
