PROVISIONAL SPECIFICATION.
Improvements in Sight Feed Lubricators.
I FRED WATMOUGH of 151 Round Street, West Bowling, Bradford in the
County of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to apply lubricators on the displacement principle,
so as to supply oil from one reservoir to any number of cylinders, steam chests or
other machinery of equal or varying pressures.
I employ an ordinary tube connected to the sight feed tube; at one end of the
tube is a spring valve which can be regulated from the outside to suit any required
pressure; at the other end of the said tube is a set valve, to keep the tube charged
with lubricant; this apparatus is attached to the cylinders or valve chests and
connected by tubes to a lubricant reservoir; from the bottom of the said reservoir
is a tube passing upwards and having an enlarged condenser chamber with suitable
air valve and connected by another tube to the main steam pipe, by this means
with one reservoir any number of cylinders or valve chests working at different
pressures can be lubricated efficiently; or the regulating valve at the top of the
tube may take the place of the set valve at the bottom of the tube, and the pressure
regulated by it from the bottom.
In this arrangement there are no working parts required such as pumps and
the like.
My invention can be applied to an ordinary self contained sight feed displace-
ment lubricator so as to work on a low pressure steam chest or cylinder.

COMPLETE SPECIFICATION.
Improvements in Sight Feed Lubricators.
I FRED WATMOUGH, of 151 Round Street, West Bowling, Bradford in the
County of York, 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:—
The object of this invention is to apply lubricators on the displacement principle
so as to supply oil from one reservoir to any number of cylinders, steam chests, or
other machinery of equal or varying pressures.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side view of part of a sight feed lubricator with part of my
improvements applied.
Fig. 2 shows my improved sight feed tube applied to high and low pressure
cylinders of steam engine.
I employ an ordinary tube A connected to the sight feed tube B, at one end of
the tube is a spring valve C, which can be regulated from the outside to suit any
-required pressure; at the other end of the said tube is a set valve D to keep the
tube charged with lubricant, this apparatus is attached to the cylinders or valve
chests E, and connected by tubes F, to a lubricant reservoir G, from the bottom
[Price 8d.1

page_text: of the said reservoir is a tube H, passing upwards and having an enlarged con-
denser chamber J, with suitable air valve J', and connected by another tube K to
the main steam pipe L ; (by this means, with one reservoir any number of cylinders
or valve chests working at different pressures can be lubricated efficiently; or the
regulating valve C at the top of the tube, may take the place of the set valve D
at the bottom of the tube, and the pressure regulated by it from the bottom.
In a suitable position upon the pipe or tube F, I fix or attach a reducing
valve M for reducing or regulating the pressure for low pressure cylinders.
In this arrangement there are no working parts required such as pumps and
the like.
My invention can be applied to an ordinary self contained sight feed displace-
ment lubricator so as to work on a low pressure steam chest or cylinder.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In sight feed lubricators the use and employment of spring regulating valve C,
with or without the set valve D, tubes F and I, lubricant vessel G, condenser
chamber J, with air valve J¹ and tube K with or without reducing valve M, as
and for the purposes such as shown and described.
2. The use and employment of sight feed displacement lubricators applied to low
pressure cylinders, or high and low pressure cylinders together, as and for the
purposes such as shown and described.
