Improvements in Apparatus to be employed in the Lubrication of
Steam Engines.
I, JAMES BARBOUR, of Falls Foundry, Belfast, County Antrim, Ireland,
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to means of lubricating the crosshead slippers and slides
of steam engines, and consists in the construction and application of improved
appliances operating as a pump, said appliances being so arranged that the
movement of the crosshead or crosshead slipper will by appliances hereafter
described force the oil or other lubricant to the part to be lubricated, thus ensuring
positive automatic lubrication.
According to this invention, in vertical steam engines, I place at the bottom of
the crosshead slide an oil receptacle, having a connection by means of piping,
either to the top of the crosshead slipper or crosshead slide. Attached to the
under side of the crosshead slipper is a plunger, which on the down stroke of the
crosshead, enters the oil and forces the oil or other lubricant up the piping 'to
the top either of the crosshead slipper, or of the slide. Or the plunger attached
to the crosshead slide may be provided with a valve and connection' to the top of
crossbead slide, the plunger in this case fits and works into a recessed chamber
filled with oil, or other lubricant in the oil receptacle, and forces the oil up to the
top of crosshead slipper.
In the oil chamber, a conical valve may be used, which is kept in position by
means of a spiral spring; the recessed chamber is so placed in the oil receptacle,
that when the plunger attached to the crosshead slipper is withdrawn, the oil flows
freely into the chamber, and on the plunger coming down 'the valve is forced
open, and the oil forced through and up to the top of the crosshead slipper or
crosshead slide.

Improvements in Apparatus to be employed in the Lubrication of
Steam Engines.
I JAMES BARBOUR, Engineer of Falls Foundry, Belfast Ireland 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 the method of lubricating the crosshead slippers and
slides of steam engines, and consists in the use and application of a pump, so
arranged that the movement of the crosshead or crosshead slipper will force the oil
or other lubricant to the part to be lubricated, thus obtaining positive automatic
lubrication

page_text: According to this invention in vertical steam engines I place at the bottom of
the crosshead slide an oil receptacle fitted with a pump, having a connection by
means of piping either to the top of the crosshead slipper or crosshead slide,
attached to the under side of the crosshead slipper is a plunger which on the
downstroke of the crosshead enters the punip and forces the oil or other lubricant
up the piping either to the top of the crosshead slipper or slide.
Or the plunger attached to the crosshead slide may be provided with a valve
and connection to the top of the crosshead slide, the plunger in this case fits and
works into a recessed chamber filled with oil or other lubricant in the oil receptacle
and forces the oil up to the top of crosshead slipper.
In the pump a conical valve may be used, which is kept in position by means of
a spiral spring; the pump is so placed in the oil receptacle that when the plunger
attached to the crosshead slipper is withdrawn the oil flows freely into the pump
and on the plunger coming down the valve is forced open and the oil forced
through and up to the top of the crosshead slipper or crosshead slide.
Such being the nature and object of this my said invention, the following is a
complete description of same, reference being had to the accompanying drawings
in which
Fig. I is a front elevation of as much of a vertical engine as will shew the nature
of my invention.
Fig. II is a side elevation of Fig. I.
Fig. III is a plan view of Fig. II.
Fig. IV is a view shewing an alternative method to that shewn in Figs. I
II & III.
Fig. V is a section of the oil receptacle shewing another arrangement of valve
to that shewn in Figs. I II & IV.
a
This method, of lubricating any desired part of the engine is by attaching
plunger to the crosshead slipper 2 and on the down stroke of the engine
this plunger 1 enters a pump 3 in an oil receptacle 4. the oil receptacle being
placed at the bottom of the crosshead slide. The plunger on entering the pump 3
forces open the valve 5 and forces the oil which was on the top side of the
valve 5 to the underside of the valve and up the piping 6 to any desired part.
In Figs. I and II the piping leads to the top of the crosshead slide, on the with-
drawal of the plunger 1 from the pump the spiral spring 7 shuts the valve and
prevents the oil getting back to the oil receptacle.
Fig. IV shews an alternative method of forcing the oil to any desired part.
The plunger 1 in this case is provided with a valve 5 and works into a recessed
chamber 8 in the oil receptacle, filled with oil, on the plunger 1 coming down the
oil forces open the valve 5 and the oil is forced up the piping 6 to any desired part
in Fig. 1V the pipe 6 leads to the top of crosshead slipper, on the plunger being
withdrawn the weight of the valve & the pressure of the oil shuts the valve and
prevents the oil returning.
-
In Fig. V the valve 5 in the oil receptacle 4 is provided with a plunger X.
The action is as follows When the plunger 1 attached to the crosshead slipper 2
on the downstroke comes in contact with the plunger X it forces it down and
opens the valve 5 forcing the oil that was on the top side of the valve 5 through
and up the piping 6 to the part or parts to be lubricated on the upstroke of
the engine the spring 7 shuts the valve and prevents the oil getting back to the
oil receptacle.
It is obvious that in this case the plunger 1 attached to the crosshead slipper
may be dispensed with and the slipper or crosshead become the direct means of
operating the plunger X.
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 combination of a plunger moved and held by a reciprocating part

page_text: of the engine & a recessed chamber fitted with a valve so that when the plunger
enters the recessed chamber the combination forms a pump for the purpose set
forth.
2nd. The combination of plunger and recessed chamber, the plunger being fitted
with a valve for the purpose set forth, and as described.
3rd. A plunger pump as shewn in Fig. 5, operated by a reciprocating part of the
engine for the purpose set forth.
