PROVISIONAL SPECIFICATION.
Improvements in Sight Feed Lubricators.
I HENRY JOHN FREETH BECKWITH Brewery Engineer of 58 Malmesbury Road
Bow in the County of Middlesex do hereby declare the nature of this invention to be
as follows:-
My said Invention has for its object to Improve the construction and action of
visible feed lubricators and consists in forming the condensing chamber or chambers
in or part of the body of the lubricator itself by a cylindrical or other partition so
that the oil being heated by the steam and hot liquor surrounding it is rendered more
fluid and only one connection is necessary in the steam pipe or valve chamber to
which the lubricator is fixed. Also the number of valves are less than usual and
easily controlled. The body of the lubricator being placed above the outlet to steam
pipe and above the glass sight-tube sufficient head of condensed water or pressure
to work the lubricator is obtained without the necessity of separate vessels or
attachments.

HENRY JOHN FREETH BECKWITH of 58 Malmesbury Road Bow in the County of
Middlesex, Brewers Engineer, do hereby declare the nature of my said 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 consists in forming the condensing chamber or chambers in or
part of the body of the lubricator itself by a cylindrical or other partition so that the
oil being heated by the steam and hot liquor under and around it, is rendered more
fluid and only one connection is necessary in the steam pipe or valve chamber to
which the lubricator is fixed.
Also the number of valves are less than usual and easily controlled. Sufficient-head
of condensed water or pressure to work the lubricator is obtained without the necessity
of a separate connection to the steam pipe.
In carrying out this Invention I make the body of the lubricator rather larger than
is usual and cast a small chamber in it as shewn, this chamber is fed from a similar
chamber or condenser placed higher than the outlet of the lubricator to the steam
pipe, and the water contained in same is led by a pipe to the bottom of the body
of the lubricator so that the oil may be pressed to the top part of the body and
flowing over the feed tube it is led to the valve which regulates the feed or supply
at the base of the sight glass.
The water being trapped in the sight glass the globules of oil float up same and
into the mainsteam pipe at the outlet.
The heating chamber may be placed in the body of any Sight Feed Lubricator as
shewn for example in the Figures 3 and 4, the water as before being led by a pipe
to the bottom of the body and pressing the oil upwards it is regulated by the small
valve in such quantities as may be desired and then the oil floating up the tube
passes out into the steam pipe.
Thus only one connection is made in the steam pipe or valve chest to which it is
attached also the oil in the body of the lubricator if found sluggish is rendered suitable
to work freely in small globules and the number of valves is reduced.
Figure 1. Shews a side section of a lubricator constructed according to this
Invention.
.
Figure 2. Is a front section of same.
Figure 3. Shews the heating chamber placed at base of sight glass.
Figure 4. Is a side view of same.
When this lubricator is attached to the steam pipe or valve chest, in starting to work
same, the plug A is removed and the body of the lubricator filled with oil, water is
then poured in at B and flowing down the pipe C, fills same, also the inner heating
chamber C³ and the pipe leading to the bottom of the body. Water also flows down

page_text: pipe D, to fill the sight glass, steam being now turned on at E an equal pressure is
obtained throughout and by adjusting the regulating valve F, the globules of oil are
allowed to pass up the sight glass and out into the main steam pipe or chest.
Having now particularly described and ascertained the nature and object of my
Invention and in what manner the same is or may be performed I declare that what
I claim is.
The combination and arrangement of the heating chamber in the body of sight
feed lubricators substantially as described and shewn in the accompanying drawings.
Dated this 25th day of January 1888.
