IMPROVEMENTS IN LUBRICATORS
Year: 1884

I, DAVID JONES of Inverness, in the County of Inverness, Locomotive Engineer
to the Highland Railway Company, do hereby declare the nature of my invention
for "IMPROVEMENTS IN LUBRICATORS 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 of the kind shown and
described in the specification of former Letters Patent granted to me dated the 24th
day of April A.D. 1874 N° 1429 such lubricators being for lubricating the cylinders
and valves of steam and other engines. In that specification there was shown and
described a lubricator without either valve or cock, the flow of lubricant from
which was regulated by a pad or retarder, the pressure whereof on a perforated
plate beneath it, was adjusted to requirements by a screw arrangement.
In a lubricator according to the present invention the outflow of lubricant is
regulated by a screwed spindle the end of which is so formed as to more or less
close the outflow opening.
In the accompanying sheet of illustrative drawings Fig 1 is an elevation, Fig 2 a
vertical section and Fig 3 a plan or top view of a lubricator according to my
invention.
A is the lubricator cup or reservoir for holding lubricant such as oil, tallow, and
the like which is supplied to it when desired from the supply chamber C through
the hole C¹ in the partition B. D is a screwed spindle passing through the top of
the supply chamber C. This spindle forms a valve that normally closes the hole C¹.
E is a second spindle whose lower end constitutes a regulator or retarder for
regulating the overflow of lubricant from the reservoir A to the steam cylinder or
part to be lubricated. This spindle E passes through the spindle D and is formed
at its lower end with an extension or part E* of smaller diameter than the main
portion of the spindle. A² is a partition in the lower part of the cup A, it is formed
with a hole of stepped form to receive the lower portion of spindle E. The area of
opening between the spindle E and the partition A² may be regulated to any desired
extent by adjusting the spindle E. For this purpose it is shewn with a screw thread E'
formed on it, and taking into a corresponding screwed nut F, carried by the
spindle D, but other means of adjusting spindle E may be used. It will usually
be advantageous to leave only a small opening for escape of lubricant between

When the spindle D is raised to admit lubricant from the chamber C to the cup or
reservoir A the spindle E is raised with it, this spindle E again taking its proper

handles for operating the spindles D and E respectively. The lubricant is caused
to pass from the cup or reservoir A to the cylinder or valve to be lubricated by the
production of a partial vacuum or unequal pressures at each stroke of the piston as
will be well understood.
In the improved lubricator as above described the steam tight and other faces
may be flat or at an angle.
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 :-
1. In a lubricator of the kind hereinabove referred to the use for regulating the
outflow of lubricant of a spindle such as E extending through the top of the
lubricator and able to be adjusted to regulate the outflow opening without removing
the cover of the lubricator substantially as described.
2. The lubricator constructed arranged and operating substantially as hereinbefore
described and shown in the drawings.
