Improvements in Automatic Lubricators for Engine Cylinders and
the like.
We HARRY INGREY and GEORGE DEANS, Engineers, both of Baldock,.
Hertfordshire, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in automatic lubricators for engine cylinders
and the like has for its object to provide a simple and exceedingly cheap lubricator
that shall be thoroughly efficient in its action, not liable to get out of order and
that can readily be regulated to deliver the required amount of lubricant and shall
not leak when out of action.
.
The lubricator consists essentially of a double ended ball or other similar valve
working between two seats in a small chamber communicating with the bottom of a
lubricant reservoir and with the interior of the engine cylinder. When steam is
admitted to the engine cylinder it acts on the valve and forces it against its upper
seat and thus prevents any more lubricant entering the small chamber. When the
exhaust takes place the valve drops on to its lower seat but before it seats itself a
certain amount of lubricant has passed beyond the valve and into the cylinder.
In order to make the chamber adjustable so as to increase or diminish the escape
of lubricant, one valve seat is formed on a plug that can be screwed into or other-
wise adjusted in the small chamber.
The valve apparatus may be formed in a separate piece of metal that can be
secured to the engine cylinder at one end and to the lubricant reservoir at
the other.

Improvements in Automatic Lubricators for Engine Cylinders and
the like.
We HARRY INGREY and GEORGE DEANS, Engineers, both of Baldock,.
Hertfordshire, 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 :-
This invention for improvements in automatic lubricators for engine cylinders
and the like has for its object to provide a simple and exceedingly cheap lubricator
that shall be thoroughly efficient in its action, not liable to get out of order and
that can readily be regulated to deliver the required amount of lubricant and shall
not leak when out of action.
The lubricator consists essentially of a double ended ball or other similar valve

a lubricant reservoir and with the interior of the engine cylinder. When steam is

seat and thus prevents any more lubricant entering the small chamber.
the exhaust takes place the valve drops on to its lower seat but before it seats
itself a certain amount of lubricant has passed beyond the valve and into the
cylinder.
In order to make the chamber adjustable so as to increase or diminish the escape
of lubricant, one valve seat is formel on a plug that can be screwed into or other-
wise adjusted in the small chamber.
The valve apparatus may be formed in a separate piece of metal that can
be secured to the engine cylinder at one end and to the lubricant reservoir at
the other.
The accompanying drawing is a vertical section of a lubricator constructed
according to this invention.
The lubricator casing a provided with a short barrel or hollow plug screwing
into the cylinder to be lubricated is provided in the interior with a small chamber b
having a fixed valve seat g at its upper end and a removable valve seat f at its
lower end formed on the end of the nozzle k that screws into the casing a.
The chamber communicates by the passage c in the nozzle k with the interior of
the cylinder and by the passage e in the casing a with the lubricator reservoir d.
A double ended valve h works in the valve chamber, the size of which is adjusted
by screwing up or down the nozzle k.
Normally the valve h rests on its lower seat g and the chamber is full of
lubricant but none can pass through the passage c into the engine cylinder.
When steam is admitted to the engine cylinder it acts on the valve h and forces
it against its upper seat g thus preventing the entrance of more lubricant from the
reservoir into the chamber b. When the exhaust takes place the valve / drops
on to its lower seat f closing the passage c, but during its period of lift, a certain
amount of lubricant has passed through the passage into the cylinder for
lubricating purposes.
The amount of lubricant supplied at each operation is regulated by adjusting
the distance between the valve seats fand 9, and therefore the lift of the valve h,
as described above.
The double ended valve may be replaced by a ball.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1. An automatic lubricator for engine cylinders and the like consisting of a
lubricator casing having a small chamber, valve seats at opposite ends of the casing
governing the inlet from the lubricant reservoir, and the outlet to the cylinder, a
double ended or ball valve within the chamber, and a reservoir for the lubricant.
2. An automatic lubricator for engine cylinders and the like consisting of a
double ended valve working between two seats in a chamber supplied with lubricant
from the lubricant reservoir past one seat and admitting the lubricant past the
other seat to the cylinder.
3. An automatic lubricator for engine cylinders and the like substantially as
described and illustrated in the accompanying drawing.
