Improvements in Sight-feed Lubricators.
Year: 1895

page_text: Improvements in Sight-feed Lubricators.
We, JOHN ALFRED MORRIS and WILLIAM THOMAS HATCH, both of the
Empire Works, Great Bridgewater Street, Manchester, in the County of Lancaster,
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates to lubricators for supplying oil against pressure to the
cylinders or other parts of steam or other engines though it may also be applied
to the lubricating of journals or parts of machinery.
The invention consists essentially in the construction of the lubricator with a
forcing chamber in which works a reciprocating vane and a sight feed or other
feed tube connected to the forcing chamber by a suitable non-return valve and to
the oil reservoir placed above or in other convenient position by a drip valve or
tap through which the oil is admitted in the desired quantity.
The
We construct a metal casing of cylindrical or partly cylindrical shape and in
this we place a reciprocating vane with a rotary or semi rotary movement.
casing is divided into separate chambers by a division plate or diaphragm in which
is placed an outlet valve or valves. The vane is pivoted to one side of the
diaphragin and in the vane chamber is an inlet port through which the oil enters
closed or controlled by a suitable non-return valve of flap or other suitable
construction. The vane is preferably provided with a valve which opens as it
moves in one direction and closes as it moves in the reverse direction.
The vane
is moved to and fro by a crank or arm attached to its spindle outside the chamber
and which is connected either by connecting rod gearing or other means with some
moving part of the engine or machine.
One side of the chamber is made removable so that the internal parts may be
easily accessible for inspection removal or repair.
At present we prefer to make the apparatus single acting with the vane depending
from one side of its spindle but if desired it may be made double acting and the
vane made to extend from side to side of the chamber in this modification the
position of the inlet and outlet valves would be changed and the division plate or
diaphragm would be somewhat of V shape covering or protecting the inlet port.
Above the iulet port and inlet valve is placed a feed tube preferably of glass to
allow of the feed being in sight and in this tube is placed a suitable drip valve
and tap through which the lubricant can be admitted drop by drop at any speed
that may be required.
The oil reservoir is placed above the feed tube or in any suitable position and
the feed tube may be connected thereto by piping thus the oil may be supplied
direct if desired from the original containing vessel.

page_text: We, JOHN ALFRED MORRIS and WILLIAM THOMAS HATCH, both of the
Empire Works, Great Bridgewater Street, Manchester, in the County of Lancaster,
Engineers, 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 relates to lubricators for supplying oil against pressure to the
cylinders or other parts of steam or other engines though it may also be applied
to the lubricating of journals or parts of machinery.
The invention consists essentially in the construction of the lubricator with a
forcing chamber in which works a reciprocating vane and the sight feed or other
feed tube connected to the forcing chamber by a suitable non-return valve and to
the oil reservoir placed above or in other convenient position by a drip valve or
tap through which the oil is admitted in the desired quantity.
It will be fully described with reference to the accompanying drawings.

A metal casing or structure A. of cylindrical or partly cylindrical contour is
constructed with a diaphragm B dividing it into two parts an upper chamber C
and a lower chamber D. The diaphragm B is preferably situated in the centre or
across the diameter but it may be placed in any other convenient position to form
the chambers C and D. The upper chamber C may be of any convenient shape
but the lower chamber D is curved or circular in shape forming the arc of a circle
along its lower surface d.
In the lower chamber D we place a reciprocating vane E the bottom edge of
which fits closely against the curved surface d and the sides of which fit closely
against the back and front sides of the chamber but so as to move to and fro freely
therein. The vane E is pivoted in the chamber and is oscillated therein by a
crank or lever F actuated by any moving part of the engine or machinery upon
which the lubricator is placed. The vane E is fitted with a small valve G
which allows the oil to pass from the inlet side to the delivery side of the vane
opening as the vane moves in one direction and closing as it moves in the reverse
direction.
The diaphragm B is fitted with a valve H through which the oil is forced
by the vane from the lower or vane chamber D to the upper or delivering
chamber C a plug or screw h being provided to control or regulate the lift of the
valve H.
The vane chamber D is provided with an inlet port K through which the oil is
drawn by the vane and is fitted with a valve k which prevents the oil being forced
or splashed back as the vane oscillates and the delivery chamber C is provided
with a delivery pipe L and has attached to it an air chamber c which provides for
the smooth and continuous working of the apparatus and delivery of the oil.
the delivery pipe L is fitted a back pressure or non return valve 1.
In
The inlet port K is connected with the oil cup or reservoir M by a feed tube N
preferably of glass to allow of the feed being in sight. Above the tube N in the
bottom of the oil cup M is fitted a drip valve or regulating valve P with regulating
spindle and knob P for allowing any desired quantity of oil to be supplied to the
chamber D preferably drop by drop at any speed that may be required.
The oil cup or reservoir M is placed above the feed tube N and attached to the
top of the air chamber c or in any other suitable position or instead of an oil
cup such as M the feed tube N may be attached by piping or otherwise with any

page_text: oil reservoir or supply thus the oil may be supplied if desired direct from the
original containing vessel.
One side R of the casing is made removable being affixed by screws or bolts r
so that the internal parts may be easily accessible for inspection removal or
repair.
At present we prefer to make the apparatus single acting as shown but if desired
it may be made double acting by connecting the inlet port with the vane chamber D
at both sides of the vane and providing two delivery valves in the diaphragm in
which case the apparatus may be made of triangular shape with a V shaped
diaphragm above a delivery valve being placed in each arm of the diaphragm.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is;-
1. A sight feed lubricator constructed with a forcing or inlet chamber with an
oscillating vane reciprocating therein connected to the oil reservoir by a sight feed
tube and a delivery chamber to which is attached a delivery pipe substantially as
described.
2. A lubricator for engines and other machines having the several parts constructed
and arranged in combination substantially as described and shown.
