An Automatic Sight Feed Lubricator for Cylinders of Engines which run with the load on and off intermittingly.

page_text: An Automatic Sight Feed Lubricator for Cylinders of Engines which
run with the load on and off intermittingly.
We, EDWIN PARSONS, of Tekoa, Queen's Hill, Pentonville, Newport on Usk, in
the County of Monmouthshire, Mechanical Engineer, and PHILIP HOWARD, of Auck-
land House, Corporation Road, Newport on Usk, Mechanical Engineer, do hereby
declare the nature of this invention to be as follows:-
The lubricator consists of a resevoir for containing oil or the like, furnished
with a regulating valve or tap near the bottom, the said valve or tap being adjust-
able for any number of drops per minute. The oil drops from valve into a cup or
receiver, and is strained through wire gauze or the like. At the underside of this
cup, or in connection therewith a valve is furnished in communication with engine
cylinder, opening outwards from the cup but inwards towards engine cylinder.
The action is as follows, for example in winding engines:-The driver brings his
load up towards the top of the pit, and then shuts steam off; there is afterwards a
vacuum formed in the cylinder, and the oil which has accumulated in the cup
during the winding with steam on is at once drawn into the cylinder thus lubricat-
ing the cylinder piston & valve for the coming wind, & its principle is similar
to that of a man standing by the engine & oiling her ready for each coming wind,
and we claim the addition or application of an automatic lubricator which shall be
furnished with an inlet valve the inlet valve being worked by the partial vacuum
formed in cylinders of intermittent running engines.

An Automatic Sight Feed Lubricator for Cylinders of Engines which
run with the load on and off intermittingly.
We, EDWIN PARSONS, of "Tekoa," Queen's Hill, Pentonville, Newport on Usk,
in the County of Monmouth, Mechanical Engineer, and PHILIP HOWARD,
of Auckland House, Corporation Road, Newport on Usk, in the County
of Monmouth, Mechanical 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 lubricator consists of a reservoir A for containing oil or the like, furnished
with a regulating tap or regulating valve B near the bottom the said tap or valve

page_text: being adjustable for any number of drops per minute. The oil drops into a cup
or receiver C and is strained through wire gauze D or the like. At the underside
of this cup or in connection therewith a valve E is furnished communicating with
engine cylinder opening outwards from the cup but inwards towards engine cylinder.
The action is as follows for example in winding engines. The driver brings his load up
towards the top of the pit and then shuts steam off: there is afterwards a vacuum
formed in the cylinder and the oil which has accumulated in the cup during the
winding with steam on is at once drawn into the cylinder lubricating the cylinder
piston and valve ready for the coming wind, and its principle is similar to that of
a man standing by the engine and oiling her ready for each coming wind. We
append a drawing in order that our invention may be clearly understood.
Having now particularly described the nature of our said invention and the
manner the same is to be performed, we declare that what we claim is:-
1. An automatic lubricator which shall be furnished with an inlet valve E, the
said inlet valve being worked by the partial vacuum formed in cylinders of inter-
mittent running engines.
