COMPLETE SPECIFICATION.
Improved Apparatus for Regulating the Supply of Lubricating OiI.
to Gas Exhausters, Pumps, and Rotary Engines.
I WILLIAM REGINALD CHESTER, The Woodlands, Mapperley Hill, Nottingham,
Civil 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 :-
Ounications of apparatus,
sectional view of the apparatus to be used when the specific gravity of the lubricant
is less than water.
The second modification shows at Figure 2 a vertical sectional view of the
apparatus used when the specific gravity of the lubricant is greater than water.
Figure 3 a vertical sectional view of a sight feed lubricator which may be
attached to either apparatus.
The corresponding parts in each figure are indicated by the same numbers.
where necessary.
The first modification of apparatus consists of a cylinder 1 of cast iron or other
suitable material provided with a piston 2 and piston rod 3 working through a
gland 4 at the top of the cylinder which has a duct or oil passage 5 cast in the side
with a boss at the bottom attached to a stop cock 6 for shutting off or regulating
the flow of the lubricant, at the bottom of the cylinder is a steam or water supply
pipe 7 provided with a stop valve or cock 8 to regulate the supply of steam or
water under pressure.
The cylinder rests on a pedestal 9.
Before putting the apparatus into action the piston 2 is pushed to the bottom of
the cylinder, and the space above it is filled with the lubricant through a hole
afterwards closed with a plug 10.
Steam or water under pressure is turned on at the stop valve 8 attached to a
steam supply pipe 11 at a slightly greater height than the top of the cylinder thus
ensuring a supply of condensed water only to the cylinder, which acting on the
underside of the piston subjects the lubricant to a similar pressure to that in the
supply pipe 11. If the pipe 11 be coupled to a water supply pipe under pressure
then the pressure of the water acts in a similar manner on the underside of the
piston thus subjecting the lubricant to a similar pressure to that of the water.
The second modification of improved apparatus shown at Figure 2 used when
the specific gravity of the lubricant is greater than water consists of a cylinder 1
resting on a pedestal 9.
When empty the cylinder is filled with the lubricant through a hole at the top
afterwards closed with a plug 10, the steam or condensed water is admitted through
a pipe 12 passing through the bottom of the cylinder and connected to a stop
valve 8 to regulate the supply of steam or water from the pipe as described in
the first mudification, the pressure being on the top of the lubricant, the lubricant
is forced through a pipe 13 into a sight feed lubricator shown in vertical section at
Figure 3. The bottom of the pipe 13 is attached to a stop cock 6 connected to
the bottom of the cylinder.
The sight feed lubricator is an apparatus for regulating the flow of the lubricant
to the exhauster, pump or rotary engine, and is common to both forms of cylinder
shown at Figures 1 and 2, it is attached to either of the stop cocks 6.

page_text: The lubricant is regulated by a valve 14 shown at Figure 3 and admitted to a
glass tube 15 at any reasonable speed through a nozzle 16. Below the glass tube a
duct 17 is arranged to form a seal in order to prevent any of the tarry gases,
vapors, or liquids escaping from the exhauster into the glass tube which would
discolour it and destroy its usefulness as a sight feed.
The lubricant is admitted to the exhauster pump or rotary engine, by a valve 18
which also serves to shut off the gas in case the apparatus should require to be
taken to pieces for cleaning or repairs. The apparatus is attached to the exhauster
by a screw 19.
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 :-
The construction and employment of improved apparatus for regulating the
supply of lubricating oil to gas exhausters, pumps and rotary engines, substantially
as described and illustrated in the drawings annexed.
Dated this Thirteenth day of October 1894.
