PROVISIONAL SPECIFICATION.
Improvements in Cylinder Sight Feed Lubricators.
I, JOHN WILLIAM HOLDEN of 12 Vincent Avenue Chorlton cum Hardy near
Manchester in the County of Lancaster, Engineer do hereby declare the nature of
this invention to be as follows:-
My said invention has for its object to improve the construction & action of
visible feed lubricators, & to feed solid grease-preferably that known as
"Asbestoline"-& other lubricants into cylinders. In carrying out my invention
I employ a lubricator cup or vessel having two through & separate communications,
one of which is a separate steamway, preferably taken up through the stem or
base of the lubricator which is screwed into the cylinder, but being, or branching
off, apart or separate from the sight glass, & carried up through & close to the top
of the cup or vessel of the lubricator.
The other communication being by means of a sight glass, placed preferably
beneath the cup or vessel of the lubricator & having communication with the cup
or vessel through an opening or aperture, & being fitted at its lower end into the
stem or base of the lubricator, the communication being completed by means of a
separate hole or aperture through the stem or base & opening into the cylinder &
the feed of the lubricant & effect from the cylinder being controlled by suitable
valves at convenient places.

COMPLETE SPECIFICATION.
Improvements in Cylinder Sight Feed Lubricators.
I, JOHN WILLIAM HOLDEN, of 12 Vincent Avenue, Chorlton cum Hardy, near
Manchester, in the County of Lancaster, 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:-
My said invention has for its object to improve the construction and action
of visible feed lubricators, and to feed solid grease, such preferably as that known
as Asbestoline," and other lubricants into cylinders.

In carrying out my invention I employ a lubricator cup or vessel having two
separate communications with the cylinder, one of which is a steamway, preferably
carried up through and close to the top of the cup or vessel of the lubricator.
The other communication through a sight glass placed beneath the cup or
vessel of the lubricator the communication being completed by means of a separate
hole or aperture through the stem or base opening into the cylinder. The two
communications are controlled by suitable valves at convenient places.
And, in order that this my invention may be better understood, I proceed to
describe it with reference to the accompanying drawings in which
Fig. 1 is a view in elevation of an improved cylinder sight feed lubricator
constructed in accordance with this invention, Fig. 2 being a similar view but in
section.
Fig. 3 is a sectional plan through the line A. B. Figs. 1 and 2.
Similar letters of reference indicate like parts in each of the figures.
a is the lubricator cup or vessel hereinbefore referred to which may be wholly
of metal to suit very high pressures; or may consist, as shewn, of a metal casing
cut away in portions and containing a cylinder of glass b to enable the contents to

c and d are the two separate communications leading from the cup or
vessel a to the cylinder. The former of these (c) forms a separate steam way
preferably taken up through the stem or base e of the lubricator (which latter
at is screwed into the cylinder) and is continued upwards as indicated at g
through and close to the top of the cup or vessel a. As will be seen more
particularly on reference to Figs. 2 and 3 a convenient manner of effecting the
separate steam communication from the cylinder to the grease cup is to drill in
the stem or base e the connecting aperture with branch communicating
with the tube c.
wheel k.
The steam passage is controlled by the valve i actuated by
The other communication or grease passage, is through the sight glass d leading
from the bottom of the cup a to the stem or base e, which latter is suitably bored
as at 7 so as to complete the communication with the cylinder. m m are valves for
controlling the lubricant conduit, operated by the hand wheels n n.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
1. A cylinder sight feed lubricator constructed substantially as and for the
purposes hereinbefore described and shewn in the accompanying drawings.
2. In a cylinder sight feed lubricator the combination with cup a and stem or
base e of the two separate communications e d, conduits gh¹l and controlling
valves i m; all arranged and operating substantially as described and shewn.
