Improvements in Lubricating Apparatus or Appliances.
I, EDOUARD BOURDON of 16 Rue Drouot, Paris, in the Republic of France,
Inventor and Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object a novel construction of lubricating apparatus or
appliances which acts under pressure, and is intended to be used for introducing
oil into steam engines, either making use, for this purpose, of the condensed steam
coming from the engine itself or using water under pressure for effecting the move-
ment of the oil.
I employ an elastic constant force as the medium for effecting the expulsion of
the oil from the lubricator.
The construction of lubricator which I have invented, is formed by the new com-
bination of known means and consists essentially of
1. A cylinder or container in which a piston is submitted on both its faces to a
pressure under which it is necessary to introduce the oil.
2. An elastic medium forming the motor, or serving as an intermediary between
a motor of any kind and the apparatus.
Given these conditions it will be seen that the piston, being in equilibrium, on
both its faces under pressure of the steam, will be independent of that pressure,
and that the entire action of the spring will be used for actuating the piston and
producing in one direction the necessary repulsion so that the oil may be introduced
into the apparatus.
The invention will be best understood by aid of the accompanying sheet of
illustrative drawings, on which
Figures 1 and 2 are plan and side elevation views respectively of a lubricator
made according to my invention.
Figure 3 is a sectional elevation, to an enlarged scale, of one of the elements
hereinafter particularly specified, of my invention.
Figures 4 and 5 are sectional plan views of varieties of my lubricator but which
are yet constructed on the same principle.
The improved apparatus is provided with a base or pedestal B which carries at
one part a cylindrical or other container C and at the other part a support S which
sustains an arrangement of a fixed actuating screw V and a trussed guide G G, on
which slides a duplex winged screw T engaging the piston rod under the action
of a pulley D which causes the fixed screw V to move in its bearings.
The piston P which moves in the cylinder C has two diaphragms or membranes ;
it is carried by a rod not shown on the drawings, and which forms part of the
duplex winged screw T.
The cylindrical container C has a cup A by which the oil is introduced, a
cock R by which either the water or condensed steam can be introduced, another
cock R' by which the oil may pass away and a further cock R for drawing off the
water or condensed steam. The cock R for the introduction of the medium for
effecting the propulsion & cock R' for the withdrawal of the oil may be controlled
from one and the same point Z. The apparatus may also act without either the
water or condensed steam being regularly introduced. The cock R can be closed
to water and be put if required in communication with the steam at a pressure
imilar to that under which the oil escapes from its cock R'.
A pulley D is provided and this pulley contains the elastic medium above
referred to. The pulley being loosely mounted on the end of the screw V of the
cylinder aforesaid with which it can be connected by the intermediation of an

page_text: elastic spring O. "This spring maintained in a state of friction on the internal
cylindrical surface of the pulley D is fixed at its other extremity to the central
ring F of the pulley.
This ring is furnished with a seating and is made solid with a face plate L by
means of a pin E; the face plate L has a handle Q by which the plate can be
actuated by hand. The apparatus acts in the following manner.
Owing to the continuous movement of the pulley D by means of a belt or strap,
the elastic spring O is placed in a state of tension until owing to this tension the
force no longer acts, there being no adherence. This spring O will then correspond
to a clock spring which is kept constantly wound up, it has then always an even
power which is the one employed for actuating the piston P. This spring arrange-
ment has already been employed in other apparatus but its application to lubricators
is new.
When the container C is full of water and has no oil in it, it will be sufficient
then to empty out and to fill it afresh, for that purpose it is necessary to bring the
-piston into an inverse position, which is effected by withdrawing the pin E which is
in the face plate L and turning the face plate in an inverse direction by means of
its handle Q.
.
In two modifications of this apparatus shown in Figures 4 and 5 the spring O
which is in the pulley may be entirely the motor. This spring enclosed in the body
of the apparatus acts on the poised piston either by a rack and pinion Figure 4 or
by a screw and nut Figure 5.
In the first case M is the racked piston rod, N is the shaft with pinion engaging
the rack.
In the second case P is the piston with two diaphragms or membranes, its rod is
screw threaded on the interior, K is the actuating screw.
In these two cases the spring acts in the same manner as in the case of horological
instruments it being wound by means of a key.
The different figures of the drawings show the apparatus without any accessory
working parts.
The lubricators may be used in connection with sight feeds by which the amount
of oil used may be ascertained.
These feeds may be placed either directly on the apparatus or at any point of
the tube which leads the oil to the machine.

· Improvements in Lubricating Apparatus or Appliances.
I; EDOUARD BOURDON of 16 Rue Drouot, Paris in the Republic of France,
Inventor, 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:
My invention has for its object a novel construction of lubricating apparatus or
appliances which acts under pressure, and is intended to be used for introducing oil
into steam or other engines either making use, for this purpose, of the condensed
steam coming from the engine itself or using water under pressure for effecting the
movement of the oil.
I employ an elastic constant force as the medium for effecting the expulsion of
the oil from the lubricator.
The construction of lubricator which I have invented is formed by the new
combination of known means and consists essentially of
1. A cylinder or container in which a piston is submitted on both its faces to the
pressure under which it is necessary to introduce the oil.

page_text: 2. An elastic medium forming the motor, or serving as an intermediary between
motor of any kind and the apparatus.
Given these conditions it will be seen that the piston, being in equilibrium, on
ooth its faces under pressure of the steam, will be independent of that pressure,
and that the entire action of the spring will be used for actuating the piston and
producing in one direction the necessary repulsion so that the oil may be introduced.
into the apparatus.
The invention will be best understood by aid of the accompanying five sheets of
illustrative drawings, on which
Figures 1 and 2 are sectional elevation and plan views respectively of a lubricator
made according to my invention.
Figures 3 and 4 are vertical sectional elevations on planes perpendicular to one
another of one of the modifications of a lubricator constructed according to my
invention.
Figures 5, 6 and 7 are sectional plan views of varieties of my lubricator which
are constructed on the same principle but in which the motive spring is simply
replaced by the action of a weight which may be returned to its original position
by various means.
The improved apparatus, Figures 1 and 2, is provided with a base or pedestal B
which carries at one part a cylindrical or other container C and at the other part a
support M which sustains an arrangement of a fixed actuating screw V and a
trussed guide GG, on which slides a duplex winged nut U engaging the piston rod
under the action of a pulley K which causes the fixed screw V to move in its
bearings.
The piston P which moves in the cylinder C is tightly packed; it is carried by a
rod T and which forms part of the duplex winged nut U.
The cylindrical container C has a cup or stopper A by which the oil is introduced,
a plugged opening D for inserting water, a cock E by which either the water or
condensed steam can be introduced, another cock H by which the oil may pass
The
away and a further cock N for drawing off the water or condensed steam.
cocks E&H for the introduction of the medium for effecting the propulsion and.
cock H for the withdrawal of the oil may be controlled by one and the same :
handle. The apparatus may also act without either the water or condensed steam
being regularly introduced. The cock E can be closed to water and put if required
in communication with the steam at a pressure similar to that under which the oil
escapes from its cock H.
A pulley K is provided and this pulley contains the elastic medium above referred
to, the pulley being loosely mounted on the end of the screw V of the cylinder
aforesaid with which it can be connected by the intermediation of an elastic
spring O. This spring maintained in a state of friction on the internal cylindrical
surface of the pulley K is fixed at its other extremity to the central ring F of the
pulley.
This ring is furnished with a seating and is made solid with a face plate L by
means of a screw nut S; the face plate L is fitted on a square socket of the screw V
and has a handle Q by which the plate can be actuated by hand. The apparatus
acts in the following manner :-
Owing to the continuous movement of the pulley K by means of a belt or strap,
the elastic spring O is placed in a state of tension until owing to this tension the
force no longer acts there being no adherence. This spring O will then correspond
to a clock spring which is kept constantly wound up, it has then always an even
power which is the one employed for actuating the piston P. This spring arrange-
ment has already been employed in other apparatus but its application to lubricators
is new.
When the container C is full of water and has no oil in it, it will be sufficient
then to empty out and fill it afresh, for that purpose it is necessary to bring the
piston into an inverse position, which is effected by withdrawing the nut S which

page_text: is in the face plate and turning the race plate in an inverse direction by means
of its handle Q.
In the modification of this apparatus shown in Figures 3 and 4, the spring O
which is in the pulley may be entirely the motor. This spring enclosed in the body
of the apparatus acts on the poised piston either by a rack and pinion, or by a
screw and nut.
In these two cases the spring acts in the same manner as in the case of horological
instruments, it being wound by means of a key which is placed on the square part
of the axis F after removing the knob.
The different figures of the drawings show the apparatus without any accessory
working parts.
The lubricators may be used in connection with sight feeds by which the amount
of oil used may be ascertained.
These feeds may be placed either directly on the apparatus or at any point of
the tube which leads the oil to the machine.
In these two Figures 3 and 4 as in the preceding ones, C represents the cylinder,
R the base forming a water reservoir, A is the filling plug, N the discharge tap,
E the water supply tap, H. the tap for discharging the oil, S is a stop tap and G is
a glass window which allows the respective levels of the liquids in the apparatus
to be ascertained.
Figure 5 represents a sectional elevation of a lubricator with balanced piston in
which the weight acting as motor and enclosed in the pressure chamber may be
lifted by means of a pressure pump which serves to effect the filling of the
apparatus. In this figure, C represents the cylinder, R the base of the apparatus,
P the piston forming the operating weight having a tight packing at its lower part,
K the oil reservoir, J the pump serving to force the oil from the reservoir K into
the cylinder C by the pipe I, A the tap for supplying the oil, N the tap for
discharging the water, E the tap for introducing the water, H the tap for
discharging the oil.
Figure 6 is a sectional elevation of a lubricator with balanced piston, in which
the weight acting as motor is enclosed in the pressure chamber and may be wound
up by means of a screw so that the apparatus may be filled. In this figure, C still
represents the cylinder, R the base forming an oil reservoir, P the piston forming
the weight having a tight packing at its lower part. V is the screw serving to
wind up the weight, and M¹ a stopper capable of acting on the screw, A is the tap
for drawing oil up through the pipe I, N the discharge tap for water, E the arrival
tap for water and H the tap for discharging the oil.
Figure 7 shows a sectional elevation of a lubricator with balanced piston in
which the weight acting as motor and enclosed in the pressure chamber may be
raised by reversing the oscillating cylinder so as to allow of its being filled. In
this figure, C represents the cylinder which may turn on an arrangement of hollow
trunnions T which serve to support it, B is a double frame supporting the bearings
of the trunnions T. JJ are two projections which engage in the stop K. in order
to hold the cylinder in a vertical position, P is the piston forming the weight
having a tight packing at its lower part. A is the filling plug, N the water
discharge tap, E the water arrival tap, and H the oil discharge tap.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that the forms, dimensions, proportions and accessory parts of the apparatus may
be varied without departing from the principle of my invention, and also that I
may employ any suitable elastic parts and any suitable materials for their con-
struction, but that what I claim is-
The improved arrangement of lubricating apparatus or appliances acting by
pressure for introducing oil into steam or other engines characterised by the
combination with a piston forming a tight packing and subjected on both faces to

page_text: the same pressure at which the oil is to be introduced (into the machinery) of an
elastic intermediate medium or an elastic motor, or composed of a suitable weight
whereby the before named piston may operate with a constant pressure for forcing
the oil into the pressure chamber substantially as hereinbefore described and shown
5 as an example on the accompanying drawings.
