Improvements in Lubricators.
I, WALTER JOHN HUBERT JONES, of 21, New King Street, Deptford, in the County
of Kent, Engineer, do hereby declare the nature of this invention to be as
follows: ་
L'
This invention has reference to a construction of lubricator in which liquid
lubricant is fed from a reservoir through a small or capillary hole to a cylinder or
vessel that is fitted with a movable piston plunger or equivalent and is adapted to be
connected at one or each end to the part or parts to be lubricated, the arrangement
being such that when the piston or equivalent is at rest, the lubricant will be
prevented by capillary action from flowing through the said hole into the cylinder or
vessel and thence to the part or parts to be lubricated but upon movement of the
piston or equivalent, a partial vacuum or reduction of pressure will be produced in one
or each end of the cylinder or vessel whereby lubricant will be intermittently fed
thereto, in small quantities at a time. By reciprocating the piston or equivalent from
the engine or other apparatus to be lubricated, the supply of lubricant to such engine
or other apparatus can be made practically proportional to the speed, and consequently
to the requirements, of such engine or apparatus.
A lubricator to act in the manner described can be constructed in various forms.
In one arrangement, the lubricant reservoir is carried by a tube in the form of a
cylinder that has its axis at right angles, or approximately so, to that of the reservoir
and is connected to the reservoir by a small capillary hole extending from the upper
part of the cylinder through the bottom of the reservoir. The cylinder is fitted with
a piston consisting of a ball and is provided at each end with an exit pipe by which.
oil can be supplied to any desired place. The reservoir and cylinder are carried by
a bar or support by which they can be oscillated and the ball thereby caused to
reciprocate in the cylinder so as to cause lubricant to be fed alternately to each end
thereof as herein before described whence it will escape by the corresponding exit
pipe.
My lubricator may advantageously be applied to the oscillating cylinder of a motor
or to other oscillating bodies requiring to be lubricated. In this case the bar or
support may be fixed to the oscillating body. The bar or support may however be
pivoted and be oscillated from a moving part of the apparatus to be lubricated or
otherwise through any suitable mechanism.
Instead of using a straight tube or cylinder a curved tube with ball piston may be
used. Also instead of oscillating the reservoir and cylindrical or other tube or vessel,
these parts may be fixed and the latter be fitted with a piston, plunger or diaphragm
arranged to be directly reciprocated by suitable mechanism."

I, WALTER JOHN HUBERT JONES, formerly of 21, New King Street, Deptford, in
the County of Kent, but now of 134, Gladstone Road, Sparkbrook, Birmingham, in
the County of Warwick, 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:—
This invention has reference to a construction of lubricator in which liquid lubri-
cant is fed from a reservoir through a small or capillary hole to a cylinder or vessel
that is fitted with a movable piston plunger or equivalent and is adapted to be connected
at one or at each end to the part or parts to be lubricated, the arrangement being such
that when the piston or equivalent is at rest, lubricant will be prevented by capillary
action from flowing through the said hole into the cylinder or vessel and thence to
the part or parts to be lubricated but upon movement of the piston or equivalent
relatively to the cylinder or vessel, a partial vacuum or reduction of pressure will be
produced in one or in each end of the latter whereby lubricant will be intermittently
fed thereto in small quantities at a time. By reciprocating the piston or equivalent
from the engine or other apparatus to be lubricated, the supply of lubricant to such
engine or other apparatus can be made practically proportional to the speed, and
consequently to the requirements, of such engine or apparatus.
A lubricator to act in the manner described can be constructed in various
forms.
Fig. 1 of the accompanying drawings shows in longitudinal section one construc-
tion of lubricator according to this invention.
In this arrangement, 1 is a lubricant reservoir carried by a tube 2 in the form of a
cylinder that has its axis at right angles, or approximately so, to that of the reservoir
and is connected to the reservoir by a small capillary hole 3 extending from the
upper part of the cylinder through the bottom of the reservoir. The cylinder is
fitted with a piston 4 consisting of a ball, and is provided at each end with an exit
pipe 5 by which oil can be supplied to any desired place. The reservoir and cylinder
are carried by a bar or support 6 by which they can be oscillated about a shaft or
centre 6* and the ball thereby caused to reciprocate in the cylinder below the
capillary hole so as to produce a partial vacuum or reduction of pressure alternately
in each end of the cylinder and cause lubricant to be fed alternately to each end of
the cylinder whence it will escape by the corresponding exit pipe 5.
My lubricator may advantageously be applied to the oscillating cylinder of a motor
or to other oscillating bodies requiring to be lubricated.
Fig. 2 shows in elevation a lubricator of the kind illustrated in Fig. 1 fixed to the
oscillating cylinders 7, shown in longitudinal section, of a motor of the kind described
in the specification of another application for Letters Patent filed by_me No. 29610
of 1896.
The bar or support may however be pivoted as at 6ª (Fig. 1) and be oscillated
from a moving part of the apparatus to be lubricated, or other moving part, through
any suitable mechanism as through a rod 8 jointed to it, or by fixing it to the
shaft 6 and making the latter a rock shaft.
Instead of using a straight tube or cylinder 2, a curved tube with ball piston 3,
may be used as shown in Fig. 3. Also instead of oscillating the reservoir 1, and
cylindrical or other tube or vessel 2, these parts may be fixed and the latter be fitted,
as shown in longitudinal section in Fig. 4, with a piston 3 or equivalent arranged to
be reciprocated by a rod 9 extending in a fluid tight manner through one end of the
tube or vessel and worked by suitable mechanism.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. A lubricator in which liquid lubricant is fed from a reservoir through a small or
capillary hole to a cylinder or vessel that is fitted with a movable piston, plunger
or equivalent, and is adapted to be connected at one or at each end to a part or parts
to be lubricated, the arrangement being such that when the piston or equivalent is at
rest, lubricant will be prevented by capillary action from flowing through the said
hole into the cylinder or vessel and thence to the part or parts to be lubricated, but
upon movement of the piston or equivalent, a partial vacuum or reduction of
will be produced in one or in each end of the cylinder or vessel whereby lubricant will
be intermittently fed thereto in small quantities at a time, as set forth.
