page_text: I GEORGE FAIROLOUGH, of Green Lane Oil Works Princoss Street Manchester in
the County of Lancaster Oil Refiner and Manufacturer 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 construction of an improved lubricator for supplying
solidified oil tallow, or other semi-solid lubricant to bearings of shafts or axles, slide
valves and such other parts of machinery as require lubrication.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the drawing hereunto annexed and the following explanation thereof.
The drawing represents a vertical section taken through about the centre of an
improved lubricator made according to my invention, the screwed disc or "follower"
hereinafter mentioned being shown solid or in elevation.
The body or cup a of the improved lubricator for containing the solidified oil,
tallow, or other semi-solid lubricant is made of a cylindrical form, having, projecting
from the central part of the bottom, a neck b, the lower portion of which is partly
screwed for attaching it to the axle bearing or other part to which it is to be applied,
and the intervening part 6" is formed square, hexagonal or otherwise, for the reception
of a screw key or wrench for tightening or releasing the same.
A small hole c for the passage of the solidified oil or grease is drilled through the
neck and screw.
The inside of the cylindrical cup a from the top to the bottom is forined with un
internal screw thread, and into this fits an external screw thread formed around the
periphery of a disc or "follower" d which (although not packed) acts in the manner
of a piston above the solidified oil or grease and as the disc ог "follower" is screwed
down, it forces the same out through the hole c above mentioned.
In order to enable the screwed disc or "follower" d to be turned round from time
to time as the lubricant may be required, it is made or fitted with a plain rod or stem e

page_text: which passes upwards through a hole in the centre of the lid and is provided at the
top with a head or thumb piece or a button y having a milled edge.
The lid is also made with a milled edge all round and it is furnished beneath with
a shallow Hange which is chased with an external screw thread fitting into the upper
part of the internal screw of the body or cup a.
It will be seen that this improved lubricator requires no packing and occupies
much less space in depth than the lubricators of this class as ordinarily constructed.
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:
The combination of a cylindrical oil cup screwed internally with a disc or "follower"
screwed externally, the said disc or "follower" being fitted with a stem passing
through the lid and provided with a milled head or thumb piece whereby it may be
turned round as required, substantially in the manner and for the purpose hereinbefore
particularly described and illustrated by the drawing annexed.
