Improvements in Lubricators.
I, CHARLES STILES of Mapperley Park Hall, West Hallam Delivery near Derby
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 certain Improvements in Lubricators applicable to all
mechanical purposes and uses, where it is necessary to give a regular, efficient and
economical form of lubrication.
I form a circular or other form of frame of any suitable shape or material preferably
of brass or gun metal, and insert a glass cylinder so as to fit therein and of any
required or necessary thickness, and permitted to rest within the base of the frame.
At the lower end of the said glass cylinder I place a loose ring or washer of asbestos
by preference and I likewise place a similar or like loose ring or washer of asbestos or
other suitable material for the purpose at and around the top of the glass cylinder,
above which a thin metal washer or disc is provided and takes thereon. A metal cap
having a screw or thread formed thereon is then screwed on to the upper portion of
the circular frame and prosses in the first instance upon the thin metal washer and the
loose ring of asbestos as also upon the glass-cylinder which in turn presses upon
the loose ring or washer of asbestos which is inserted beneath the said glass
cylinder.
A hollow tube is provided and passed through the centre of the frame, from the
upper to the lower portion of same, which has a screw formed thereon to a suitable
extent so as to enable the Lubricator to be screwed into and firmly secured in position
to the necessary portion of the cylinder of the engine, bearing or other part or
portion of the machine to which it has to be applied.
Through the centre of the hollow tube I pass a wire or wires twisted together or
otherwise within same and bent at the end or ends, having a certain quantity of
twisted yarn or other like material having capillary qualities.
An aperture is formed through the top of the case with a thread formed in it, into
which a screw plug fits and works to enable the necessary lubricant to be inserted at
will. The amount of oil contained in the Lubricator can be readily observed by means
of the transparent glass cylinder.
In the accompanying sheet of Drawings Figure 1, represents an elevational view of
my Improved Lubricator, and Figure 2, is a sectional elevation of same. The
following letters of reference indicate like or corresponding parts.
A is the circular frame of metal in which the transparent glass cylinder B, is placed
and held, also well protected from risk of damage. C, is a loose ring or washer of
asbestos or other suitable material upon which the glass cylinder is seated. D, is
another loose ring or washer of like or other suitable material just above and around
the top of the said glass cylinder. E, is a thin metal washer or ring over the asbestos
washer or ring D. F, is a metal cup having a screw or thread for it to screw into a
portion of the frame A, in which it works, upon this being screwed down it presses
upon the thin metal-washer or ring of asbestos as also upon the glass cylinder which
presses upon the lower loose ring or washer just beneath and thus securely gives a
very effective and tight joint so that no leakage can occur and the joints are not
affected by extreme heat or pressure. G, is a small tube inserted in the centre of the
Lubricator passing downward and through the screwed portion H of the metal frame,
and two or more pieces of wire are inserted and protrude through the upper and
ower ends of this tube, and around these pieces of wire the yarn or other suitable
material J, is coiled toward the end and the other end or portion is allowed to fall
over into the inner portion of the glass cylinder containing the oil lubricant and in
P1

removed for feeding the Lubricator.
It will be seen from the form of my Lubricator and arrangement of parts that no
dust or other foreign matter can mix with the lubricant and no waste or loss can take
place.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed what I claim is:
The general construction and arrangement of a Lubricating device substantially as
for the purpose and in manner herein before described and illustrated.
Dated this 28th of January 1890.
