PROVISIONAL SPECIFICATION.
Improvements in Engine Lubricators.
We JOHN ALFRED MORRIS and WILLIAM THOMAS HATCH, Engineers, .
both of The EmpireiWorks, 78 Great Bridgewater Street Manchester Lancashire,
do hereby declare the nature of this invention to be as follows:-
The object of our invention is to manufacture lubricators applicable to steam
and other engine cylinders, valve chests and analogous purposes in an improved
manner.
Our lubricator consists essentially of a reservoir to contain the lubricant; a
valve or plug cock for regulating the amount of lubricant supplied, and at the same
time shutting off the steam or other pressure from the aforesaid reservoir; and a
stand placed under the reservoir to support the whole combination.
This stand is arranged to contain a sight glass through which the quantity of
lubricant supplied can be seen, falling drop by drop on its way to the engine, thus
enabling the supply to be checked or accelerated to suit the requirements of each
individual case.
When the lubricator is fitted to any portion of an engine, where the pressure is
constant, we arrange that there shall be two passages connected with the reservoir
containing the lubricant; one for the admission of steam or other fluid pressure,
and the other to allow the lubricant to escape. The former passage is carried up
as high as possible in the reservoir, to prevent any escape of lubricant through it,
whilst the latter passage is kept as low as possible to facilitate a ready flow of
lubricant through it.
In our lubricator, both of these passages are regulated by the same valve or
plug cock.

Improvements in Engine Lubricators.
JOHN ALFRED MORRIS and WILLIAM THOMAS HATCH, Engineers, both of
The Empire Works, 78, Great Bridgewater Street Manchester, Lancashire 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:-
The object of our invention is to manufacture lubricators applicable to steam
and other engine cylinders, valve chests and analogous purposes in an improved
manner.
In the following description its application to steam engine cylinders is shewn,
from which description its application to analogous purposes will be understood,
reference being made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of the lubricator complete ready for insertion into the
steam pipe or chest of an engine. Fig. 2 is a sectional elevation of same.
A is a reservoir for containing the lubricant, filled through aperture closed by
plug B; C is an internal tube introduced to allow the steam or other pressure to
enter the reservoir; D is a hole in plug E for allowing the lubricant to escape;
E is a valve or plug having two holes or passages made in it, the one (M) for

admitting pressure into the reservoir, and the other (D) for allowing the lubricant
G is a screwed bush for compressing packing against top of plug E and
keeping same, tight and in position. H is a sight glass tube through which the
lubricant can be seen falling from the nozzle J on its way to the engine, convenient
holes being left in the hollow stand surrounding the glass tube, for this purpose.
K is a small screwed washer or bush, used for compressing the packing against
sight glass tube to keep it steam tight; or the glass might be made steam tight in
other ways such as by having the whole of the hollow stand loose from reservoir,
and screwing it to same, the latter action being utilised to form a pressure through
suitable packings, on end of glass tube to make it steam tight. L is a handle by
which the plug E is moved, so as to completely or partially shut off the escape of
lubricant and the ingress of fluid pressure.
The action of the lubricator is as follows, The handle L being placed in a
horizontal position, so as to close both inlet and outlet passages, plug B is removed
and the reservoir A filled with lubricant, after which B is replaced. The handle L
is then turned into a vertical position, thus opening a thoroughfare through both
inlet and outlet passages, & is kept in this position until the lubricant begins to
flow from the nozzle J, when L is gradually moved towards the horizontal position
until the outlet passage is sufficiently contracted, so as to only supply the requisite
quantity of lubricant. It will be noticed that if both holes or passages J and M
were equal in size, that when the outlet J is contracted, the inlet M would be
similarly contracted, so, to prevent this and always ensure the same pressure in
reservoir as in engine, we make the passage M of a larger diameter than J, or
else elongate it, so that a much greater travel of the lever L is required to close M
than J.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is
1. The combination of a sight feed lubricator with a single plug for regulating.
and shutting off both inlet and outlet passages, constructed, arranged, and operating
in the manner and for the purpose substantially as hereinbefore described and
shewn on the drawings.
2. The combination of a lubricator of the drop feed or gravity type, having the
sight glass underneath the oil reservoir, as applied in the lubrication of steam engine
cylinders, substantially as hereinbefore described and shewn on the drawings.
3. The general construction, arrangement and combination of the several and
respective parts together forming our improvements in lubricators, substantially
as hereinbefore described and shewn on the drawings.
