page_text: I, WILLIAM EDMUND SIMPSON, of 28, Victoria Street, Westminster, in the
County of London, Engineer, do hereby declare the nature of this invention to
be as follows:.
This invention relates to improvements in lubricators particularly adapted for
the hot cylinders of high speed internal combustion motors, and for lubricating
under similarly adverse conditions.
It is found that in such motors the trouble experienced in lubrication is practi-
cally overcome by adding about ten per cent. of Hake graphite to the usual lubri-
cating oil or grease, but if the amount of graphite be excessive the working parts
become clogged. The graphite and grease is sometimes mixed in the required
proportions and applied as a paste by a lubricator of the "Stauffer" type, but
for many purposes it is essential that a sight-feed lubricator be employed.
According to the said invention a sight-feed lubricator is so constructed that
graphite and oil may be supplied in constant proportions, though the supply of
mixture may be varied, or shut off altogether when not required. In one arrange-
ment of such a lubricator, a single cup may be divided by a vertical partition into
two reservoirs, one for the graphite and one for the oil, each having the usual
filling devices, regulating valves, and also glass portions through which the
quantities of lubricants in the reservoirs and also the quantities passing through
the valves may be always visible. The valves are preferably of the screw-down or
needle type having screwed stems on which are fixed pinions gearing with a
central pinion having a milled head, and the dimensions of the valves, or the
pitches of the screws, may be so varied that the rotation of the milled head in
one direction or the other produces an increase or a reduction of the amount of
lubricant supplied, while maintaining constantly the same proportions of oil and
graphite.
The two lubricants preferably pass through a single externally screwed portion
or shank, by which the lubricator is attached to the cylinder, and the lower portion
of the lubricator may be provided with plugs or cocks for inspection and cleaning
of the outlets.
The feeding of the lubricants may be assisted by the pressure in the cylinder
or in the crank-chamber, or other means, and in some cases rotary buckets or
other mechanical devices driven from the motor shaft may be employed instead of
the drop-by-drop arrangement above described, such devices in all cases being so
proportioned and operated as to maintain a predetermined proportion of oil to
graphite.

I, WILLIAM EDMUND SIMPSON, of 28, Victoria Street, Westminster, in the
County of London, 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 :-
This invention relates to improvements in lubricators, particularly adapted
for the hot cylinders of high speed internal combustion motors, and for lubri-
cating under similarly adverse conditions. It is found that in such motors the
trouble experienced in lubrication is practically overcome by adding about
10% of flake graphite to the usual lubricating oil or grease, but if the amount of
graphite be excessive the working parts become clogged. The graphite and
grease are sometimes mixed in the required proportion, and applied as a paste
by a lubricator of the Stauffer" type, but for many purposes it is essential
that a sight feed lubricator be employed.
According to the present invention a sight feed lubricator is so constructed
that graphite and oil may be supplied in constant proportion, although the supply
of mixture may be varied or shut off altogether when not required.
The invention is illustrated in the accompanying drawing, in which
Fig. 1 is a vertical section of a lubricator, and
Fig. 2 a plan corresponding thereto.
In one arrangement of such a lubricator, as illustrated in the accompanying
drawing, a single cup a may be divided by a vertical partition b into two reser-
voirs e and d, one d for the graphite, and one for the oil, each having the usual
filling devices, regulation valves, and also glass portions through which the
quantities of lubricants in the reservoirs, and also the quantities passing through
the valves may be always visible. The valves e and f are preferably of the screw-
down or needle type, having screwed stems on which are fixed pinions g, h, gearing
with a central pinion having a milled head j; and the dimensions of the
valves e and for the pitches of the screws may be so varied that the rotation of the
milled head in one direction or the other produces an increase or reduction of
the amount of lubricant supplied, while maintaining constantly the same pro-
portion of oil and graphite. The two lubricants preferably pass through a single
external screwed portion or shank k by which the lubricator is attached to the
cylinder, and the lower portion of the lubricator may be provided with plugs or
cocks such as for inspection and clearing of the outlets.
The feeding of the lubricants may be assisted by the pressure in the cylinder
or in the crank chamber, or by other means, and in some cases rotary buckets or
other mechanical devices driven from the motor shaft may be employed, instead
of the drop by drop arrangement before described.
Such devices in all cases are so proportioned and operated as to maintain a
determined proportion of oil and graphite.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
A lubricator in which separate revervoirs for oil and graphite are employed,

page_text: with valves or controlling devices, and which is constructed and operates sub-
stantially as and for the purpose hereinbefore described.
