IMPROVEMENTS IN LUBRICATING APPARATUS &
Year: 1885

page_text: I BENJAMIN JOSEPH BARNARD MILLS of the firm of Harris and Mills of
23 Southampton Buildings in the County of Middlesex, Patent Agent do hereby
declare the nature of the said Invention for IMPROVEMENTS IN LUBRICATING
APPARATUS & communication to me from abroad by Louis Dusert of 161 Rue
Rambuteau, Mâcon, in the Republic of France, Mechanician to be as follows:-
This lubricating apparatus is principally intended for the intermittent injection
of determined quantities of oil into the interior of spaces under pressure, such as
cylinders, steam boxes and others.
It can also be applied to the lubrication of mechanism of all kinds and may be
worked either by hand or automatically.
The lubricator consists in principle of a reservoir, of metal or glass, open to
atmospheric pressure and receiving the oil or other lubricating liquid, and of a
cylinder or pump body in which a single acting piston works which is operated by
hand or automatically by the machine which it is required to lubricate.
In its return stroke the piston draws oil from the reservoir either through a
valve, or through a simple opening which is uncovered by the piston at the end of
its stroke and by which the oil passes directly from the reservoir to fill the space
which the piston has created behind it.
In its reverse stroke the piston forces this oil through a valve which separates
the cylinder from the spaces to be lubricated. On the other side of the valve one
or several main tubes provided with branch tubes convey the oil to the desired
points.
.
When working automatically the piston is operated by a connecting rod which
is jointed to a crank-pin on a ratchet wheel operated by a click or driver connected
to any convenient moving part of the machine, the speed of rotation communicated
to the ratchet wheel regulates the speed of the piston and the amount of
lubrication.
When working by hand, the piston is operated by a quick threaded screw or by
a lever or even directly by simple pressure on the rod projecting outside and which
is raised by means of a spring, after each operation.

page_text: With this system, the lubricator can be placed at any convenient point of the
works or of the machine which it is required to lubricate, conduits in any required
* number convey the oil to convenient points, these conduits are provided at their
ends with stop valves and may also be provided at any convenient point with a
cock for the purpose of regulating or stopping their delivery.
This lubricator whatever may be its arrangement presents the advantage of
supplying with certainty the quantity of oil introduced at each stroke of the
piston and consequently effects a considerable economy in lubricating material
whilst at the same time assuring a regular lubrication. It is not liable to any false
working capable of producing injections of oil, and the suppression of cocks avoids
outside leakages and permits of maintaining the apparatus constantly in a clean
condition.

I BENJAMIN JOSEPH BARNARD MILLS of the firm of Harris and Mills of
23 Southampton Buildings in the County of Middlesex, Patent Agent, do hereby
declare the nature of this invention, a communication to me from abroad by
Louis Dusert of 161 Rue Rambuteau Macon in the Republic of France Mechanician,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This lubricating apparatus is principally intended for the intermittent injection
of determined quantities of oil into the interior of spaces under pressure such as
cylinders, steam boxes and others.
It can also be applied to the lubrication of mechanism of all kinds and may be
worked either by hand or automatically.
Figure 1 of the accompanying drawings represents the arrangement of such an
apparatus with automatic action.
The lubricator, properly so called, consists of a reservoir A open to atmospheric
pressure and receiving the lubricating liquid of whatever kind it may be, after it
has passed through a filter J. This reservoir may be made of metal or of glass, in
this latter case it may be provided with a graduated scale.
The oil runs out of the lower part of this reservoir by a channel B, the orifice of
which is more or less obstructed by a pointed screwed rod or valve C operated from
the exterior and intended to regulate or to interrupt the flow as required.
The channel B opens into a horizontal cylinder D, traversed by a piston E. The
bottom of this cylinder communicates by the channel F with the foot of the
lubricator in which is situated a valve Ġ opening from above downwards and
held to its seat by a spring, below this valve are placed one or several coupling
tubes H intended to receive the tubes which lead to the various apparatuses to be
lubricated..
The piston E is operated by a connecting rod I pin-jointed to a crank pin fixed
in the face of the ratchet wheel T which is operated by a driving lever R in con-
nection by any suitable means with the rod of the slide valve or with any other
part of the machine having a reciprocating motion.
Having explained the construction of the lubricator, the operation will be
readily understood. The piston E receives from the engine through the intervention
of the click or driver K and of the connecting rod I a slow to and fro motion;
when it travels towards the bottom of the cylinder D, it drives out the oil con-
tained in the latter, the valve G opens and the oil passes through the coupling
pipes H and is delivered to the parts to be lubricated. In returning, the piston
inakes a vacuum behind it, the valve G closes and the piston in arriving at the end
of its stroke uncovers the orifice B, oil from the reservoir enters the cylinder to be
again driven out therefrom in its turn as soon as the piston in its return motion
shall have again closed the orifice B.
The piston continues thus to force out at regular intervals determined and
variable quantities of oil according to the position of the point of the regulator C.

page_text: The conduits H may be of any required number and a single apparatus placed
at the most convenient point may deliver the oil to all the parts of the machine
closed or not and situated at any points. Each conduit H is furnished at its end
with a retaining valve N see Figure 4 intended to retain the oil in the interior, it
can also at any convenient point of its course be provided with a cock for the
purpose of regulating or stopping its outlet.
Figure 2 represents the arrangement of a lubricator operated by hand, the
piston E acts vertically and is worked by means of a quick threaded screw, the oil
from the reservoir enters the cylinder by the orifice B when the piston rises and is
forced out therefrom as before described through the coupling pipes H below the
valve G, when the piston descends the orifice B is closed by a valve.
Figure 3 is a similar arrangement which is specially applicable to locomotives.
This description of lubricator whatever may be its arrangement presents the
advantage of supplying with certainty the quantity of oil introduced at each stroke
of the piston and consequently effects a considerable economy in lubricating material
whilst at the same time assuring a regular lubrication. It is not liable to any false
working capable of producing injections of oil and the suppression of cocks avoids
outside leakages and permits of maintaining the apparatus constantly in a clean
condition.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The herein described apparatus for lubricating all parts of steam or other engines
whether under pressure or not or closed or open and placed in any position con-
sisting of a piston operated automatically or by hand within a cylinder of which
one of its extremities communicates either directly or by a valve with the reservoir
for the lubricating liquid the other extremity communicating by the aid of one or
several valves, with the space or spaces to be lubricated.
