Improvements in Lubricators.
I, JOHN WILLIAM HOLDEN, of Piccadilly, Manchester, in the County of
Lancaster, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to that class of lubricator in which a solid lubricant is
forced from a cylinder or container by a descending piston caused to gradually
descend by means of a screw.
This invention is designed to provide improved gearing whereby such screw may
be rotated specially applicable for use in connection with the cranks and crank pins
of steam engines.
The body of the lubricator I construct of cylindrical or other suitable form in
the usual way with a piston capable of being moved to and fro therein by means of
a screw on the piston rod round which a screwed sleeve or wheel boss is caused to
rotate
To the sleeve or boss with which the screw of the piston rod engages I attach a
crown or bevel wheel which can be rotated by a small wheel or single rotating
tooth coming into gear with it.
On the side of the lubricator I attach a bracket which carries on a suitable
spindle or stud a large wheel or pulley which can be driven by a strap or band.
The spindle upon which this wheel is mounted carries at the one end a star or
bevel wheel or the like with one two three or more teeth which engage with the
crown or bevel wheel around the piston spindle and give motion to the same.
The outlet pipe is fitted to the bottom of the cylinder or container by a ball or
other suitable joint so that it may be free to rotate and this outlet pipe is connected
to the crank (or other moving part of the machine) and rotates with it
The outlet pipe is provided with a wharve which is connected with the driving
pulley by a strap or band and conveys motion to it thereby.
Where the invention is applied to a crank pin it is necessary that the outlet pipe
should rotate and I then prefer to fit it with a wharve to dive the apparatus.
Where however the invention is applied to stationary journals the outlet pipe may
be fixed and the band to the driving pulley may come from any rotating part of the
machine that is convenient for the purpose.

COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, JOHN WILLIAM HOLDEN, of Piccadilly, Manchester, in the County of
Lancaster, 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 :-
This invention relates to that class of lubricator in which a solid lubricant is

page_text: forced by a gradually descending piston from a fixed or stationary cylinder or
container to the crank pine of steam engines or the like. And it is designed to
provide improved mechanism for depressing the piston and for connecting the
stationary cylinder or container with the rotating part to be lubricated.
It consists essentially in constructing or arranging the lubricator with the feed
or outlet pipe connected thereto by a ball and socket joint in such a way or ways as
to allow of a movement to one side or the other caused by any eccentricity or
eccentric movement thereof and thus allowing the outlet or feed pipe to be
connected between a fixed lubricator and a crank and the motion of the crank to
bo efficiently utilised for the purpose of depressing the piston of the lubricator.
The invention will be fully described with reference to the accompanying
drawings
Fig. 1. (Sheets 1 and 2. Side elevation partly in section.
Fig. 2. Side elevation partly in section showing a modification. (Sheet 2 serves
as a continuation of this fig. also.)
The body or container A of the lubricator I construct of cylindrical or other
suitable forin in the usual way with a piston capable of being moved to and fro
therein by means of a screw on the piston rod round which a screwed sleeve or
wheel buss B is caused to rotate.
To the sleeve o boss B with which the screw of the piston rod engages I attach
a crown or bevel wheel C which can be rotated by a small wheel Ď coming into
gear with it.
In carrying out my invention I find that in order to reach or ensure a required
minimum speed it is desirable to adopt a train of wheels E of a suitable number
and ratio and I impart notion to such train of wheels E from the feed or outlet
pipe Feither by a pulley G driven by a strap or band from a pulley II aflixed to
the feed or outlet pipe For from a spur wheel H' affixed thereto.
To the side of the lubricator cylinder A. I attach a bracket L which carries on a
suitable spindle g a pulley G which can be driven by a strap or band h from the
pulley H. The spindle g on which the pulley G 19 mounted carries at the other
end a small spur wheel e from which notion is transmitted to the crown wheel C
through the tiain of wheels E. The pulley G is driven by means of a strap / from
the pulley H (having one or more speeds) from the rotating outlet pipe F. The
outlet pipe is fitted to the bottom of the cylinder or container A by a ball
Joint M which leaves the outlet pipe F free to rotate and equalises any eccentricity
of motion in the connecting pipe N. The outlet pipo is in turn connected either
by the connecting pipe or conduit N that has served with or as part of a "hanjo'
lubricator or by any similar connecting pipe to the crank P and rotates with it as
shown in Fig. 1. (Sheet 2.)
""
Referring to Fig. 2 I show a modification in which the train of gearing E and
the crown wheel are driven by a toothed wheel H' on the feed or outlet pipe F
gearing with a sput wheel G₁ ou the spindle g instead of by pulleys G and II and
band h. In gearing from the feed pipe direct it is very essential that the eccentricity
of motion should not throw the geared parts out or momentarily disarrange them
so as to prevent a constant and equal motion, I therefore fit a short length of the
outlet pipe to the bottom of the cylinder or container A by any suitable joint m 80
that it may be free to rotate, and hold it igid or steady by means of a suitable
bracket. At the end of this length of the outlet pipe I arrange a ball joint M and
another length of piping F which is coupled up either to the connecting pipe or
conduit N that has served with or as part of a "banjo" lubricator or by a similar
connecting pipe to the crank from whence it receives its motion (as shewn on Sheet 2).
To transmit the motion between the separate lengths of pipe F and I arrange a
lug for other suitable device on each that they will engage and cause them to
rotate together thus actuating the crown wheel Ċ and depressing the piston of the
lubricator.

page_text: Having pow particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declaro that what I
claim 15.
1. A lubricator of the type referred to constructed with a ball and socket joint
connecting the feed pipe or conduit thereto to allow of a limited movement to one
side or the other to equalise any eccentricity or eccentric movement of the rotating
parts thus permitting a fixed stationary lubiicator to be attached or connected to a
ciank pin and the motion of the crank to be efficiently utilised for the purpose of
depressing the piston substantially as described.
2. In a lubricator of the type referred to the combination with the piston and
cylinder A of a rotating feed pipe or conduit connected thereto by a ball and
socket joint a crown wheel rotating around the piston tod and a wheel or pulley
attached to the rotating feed-pipe from which motion is transferred to the crown
wheel to depress the piston substantially as described
3. A lubiicator of the type referred to having the several parts constructed and
arranged in combination substantially as and for the purposes described and shown
with reference either to Fig. 1 or Fig. 2 of the drawings.
