I, JAMES LIONEL GRANDISON, of 119, Broughton Lane, Lower Broughton, Man-
chester, in the County of Lancaster, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in sight-feed lubricators of the self
contained condenser type and has for its object to improve the general construc-
tion of and render the same specially applicable for the steam supply pipes of
engines.
To this end I employ an oil reservoir having a sight-feed glass on one side and
a gauge glass on the opposite side and a condenser vessel at the top in continua-
tion of the said oil reservoir.
In the latter I employ a pipe the upper end of which reaches to near the top
thereof and the lower end communicates with the passage leading to the sight-
feed glass. The upper end of the said oil reservoir I form internally with a
passage adapted to link together the upper end of the sight-feed glass and the
oil supply pipe.
The latter is arranged inside another pipe which is screwed into the steam
supply pipe of the engine and communicates with the upper end of the aforesaid
condenser vessel, the said oil supply pipe projecting a suitable distance from the
end of the pipe screwed into the steam supply pipe in order to completely separate
the oil which enters the steam supply pipe from the steam which passes to the
condenser and thus prevent the passage to the latter being blocked up.

I, JAMES LIONEL GRANDISON, of 119, Broughton Lane, Lower Broughton, Man-
chester, in the County of Lancaster, Engineer, do hereby declare the nature of
this invention and in what mauner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to improvements in sight-feed lubricators of the self
contained condenser type and has for its object to improve the general construc-
tion of and render the same specially applicable for the steam supply pipes of
engines.

page_text: And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Figs. 1 & 2 being sectional side
elevations and Figs. 3 & 4 sectional plans at lines A-B and C-D of Figs. 1 & 2
respectively of my improved sight-feed lubricator.
In carrying out my invention and referring to the figures generally, I employ
an oil reservoir a having a sight-feed glass b on one side and a gauge glass c on
the opposite side and a condenser vessel e at the top in continuation of the said
oil reservoir.
In the oil reservoir a I employ a pipe f the upper end of which reaches to near
the top thereof and the lower end communicates with the passage g leading to
the sight-feed glass b. The upper end of the oil reservoir a I form internally with
a segmental passage h adapted to link together the passage i leading to the upper
end of the sight-feed glass band the oil supply pipe k by the medium of the
stop valve l.
The oil supply pipe k is arranged inside another pipe m which is screwed into
the steam supply pipe of the engine (not shown) and communicates through the
pipe with the upper end of the condenser vessel e, the pipe m being connected to
the oil reservoir a by means of the stop valve l.
In order to completely separate the oil whilst entering the steam supply pipe,
from the steam passing to the condenser vessel e and thus prevent the passage
to the latter being blocked up, I form the oil supply pipe k of such a length as to
project a suitable distance from the outer end of the pipe m screwed into the steam
supply pipe.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:.
h
In sight-feed lubricators of the type hereinbefore specified, the passage
formed at the upper end of the oil reservoir a and adapted to link together the
passage i leading to the upper end of the sight-feed glass b and the oil supply
pipe k, all substantially as and for the purpose set forth.
