PROVISIONAL SPECIFICATION.
Improved Apparatus for Supplying Lubricants to Journal Bearings
in Regulated Quantity.
I, THOMAS MUNRO of 25 Ardgowan Street, Port Glasgow, Renfrewshire,
Millwright do hereby declare the nature of this Invention to be as follows:-
This Invention has for its object to provide simple and inexpensive apparatus for
supplying or regulating the supply of lubricants such as viscous or liquified oils to
journal bearings of shafts.
The improved apparatus comprises an oil box which is placed over the bearing or
bearings to be lubricated and is provided with one or more tubes or orifices through
which the lubricant passes from the box to the bearing. In each tube or orifice is
fitted a needle connected to a plunger which is situated over the orifice and has a
reciprocating motion communicated to it whereby the lubricant is pressed into and
through the tube or orifice to the bearing. The motion of the plunger or plungers
is communicated from the shaft to be lubricated preferably by means of a lever arm
acted on by a cam or wyper on the shaft and fixed to a rock shaft on which are short
lever arms or eccentrics to which the plungers are connected.
An adjustable bracket on the bearing blocks is or may be provided to regulate
the extent of motion of the lever arm and plungers. The lubricant is thus fed by
positive action and the supply can be regulated to suit the requirements of the
bearings.

COMPLETE SPECIFICATION.
Improved Apparatus for Supplying Lubricants to Journal Bearings
in Regulated Quantity.
I, THOMAS MUNRO of 25 Ardgowan Street, Port-Glasgow, Renfrewshire,
Millwright, 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 has for its object to provide simple and inexpensive apparatus for
supplying or regulating the supply of lubricants such as viscous or liquified oils to
journal bearings of shafts.
As represented in the accompanying drawings in vertical section at figure 1 and in
end elevation at figure 2, and in modified forms in vertical section and plan at
figures 3, 4 and 5, 6, the improved apparatus comprises an oil box A, which is placed
on the cap or cover C, over the bearing or bearings B, to be lubricated and is provided
with one or more tubes or orifices D, D, through which the lubricant passes from the
box to the bearing. In each tube or orifice D, is fitted a needle E, connected to a
plunger F, preferably of helical form which is situated over the orifice and has a
reciprocating motion communicated to it whereby the lubricant is pressed into and
through the tube or orifice to the bearing. In the modification shown in figures 1,
and 2, the motion of the plunger or plungers F, is communicated from the shaft G,
to be lubricated by means of a lever arm H, acted on by a cam or wyper I, on the
shaft and fixed to a rock shaft J, on which are short lever arms K, or eccentrics to
which the plungers F, are connected. An adjustable bracket or stop-piece L, on
the bearing blocks M, is or may be provided to regulate the extent of motion of the

page_text: lever arm H, and plungers F. The lubricant is thus fed by positive action and the
supply can be regulated to suit the requirements of the bearings.
In the modification shown in figures 3 and 4 and which is adapted to be applied
to a moving bearing block, such as a crank pin bearing, the plunger F, is actuated by
an arm, fixed to it coming in contact with a stationary stop, whilst in the modification
shown in figures 5, and 6, the plunger F, is attached to a lever arm N, carrying a
plate N', which is acted on by the air in the movement of the bearing block and thus
effects réciprocation of the planger, stops L; being provided to regulate the extent of
movement.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The combination of parts constituting the improved lubricating apparatus herein-
before described.
2. In a lubricator of the kind set forth the provision of a feeding plunger and
needle actuated from the movement of the shaft in the bearing to be lubricated sub-
stantially as described.
Dated this Nineteenth day of November 1889.
