GUSTAVE DELETTREZ of 7 and 9 Rue Gide, Levallois-Perret (Seine) in the
Republic of France IMPROVEMENTS IN SELF-ACTING OR AUTOMATIC LUBRICATORS
(Partly communicated to me by Isidore Duballe of Paris, France and partly
invented by myself).
The object of this Invention is improvements in self-acting or automatic
lubricators.
The improved apparatus is constructed so as to be applied to steam ports or
inlets, the lubrication being effected by means of the condensation of the steam in
the chamber or receiver containing the lubricant.
The apparatus is composed of a chamber or receiver fixed to the engine cylinder
in any convenient manner.
The shell of the tap or cock on the lubricator is screwed to the upper part of
the receiver.
The tap or cock is turned so as to put the receiver into communication with the
funnel of the lubricator by an orifice, that is to say, when the tap handle is turned
upwards the receiver is in communication with the outer air by a conduit which
permits the filling of the receiver with the lubricant.
When the tap or cock is in a horizontal position the apparatus is in working
order and the lubrication is being effected because a hollowed part in the tap puts
two conduits into communication so that the steam entering through the steam
conduit passes into the receiver through the other conduit and condenses in the
Din 21

page_text: receiver causing the lubricant to flow in the reverse direction through the same
conduits.
The lubricator may be emptied instantaneously by putting the conduits into
communication. In this case the tap handle is turned down when the steam enters
one conduit and immediately forces out all the contents of the receiver.
In another form of lubricator the receiver is fed in the same way by turning
the tap handle upwards whilst another handle at the lower part is also turned
upwards to shut off the entry of the steam. The receiver then fills itself.
The lower part of the receiver is closed by the lower tap or cock which establishes
or intercepts communication with the steam entry.
On the sides of the receiver are arranged gauge glasses fixed in metal boxes by
soldering.

GUSTAVE DELETTREZ of 7 and 9 Rue Gide, Levallois-Perret (Seine) in the
Republic of France IMPROVEMENTS IN SELF-ACTING OR AUTOMATIC LUBRICATORS
(Partly communicated to me by Isidore Duballe of Paris France and partly invented
by myself)
The object of this Invention is improvements in self-acting or automatic
lubricators and will be clearly understood by the following description with referenco
to the annexed drawings in which I have shown two forms (as examples only) of
this improved automatic lubricator.
Figures 1 and 2 show one form of the improved lubricator in vertical section
made at right angles to each other.
Figures 3 and 4 show a second form of lubricator in vertical section and exterior
elevation.
The improved apparatus is constructed so as to be applied to steain ports or inlets
the lubrication being effected by means of the condensation of the steam in the
chamber or receiver containing the lubricant.
:
The apparatus shown in Figures 1 and 2 is composed of a chamber or receiver a
fixed to the engine cylinder in any convenient manner. The shell b of the tap or
cock on the lubricator is screwed to the upper part of the receiver a. The tap or
cock c is turned so as to put the receiver a into communication with the funnel d
by an orifice e that is to say when the tap handle is turned upwards the receiver
is in communication with the outer air by a conduit f which permits the filling of
the receiver with the lubricant. When the tap or cock is in a horizontal position
as at Figure 1 the apparatus is put in action and the lubrication is being effected
because a hollowed part g in the tap puts two conduits h and i into communi-
cation so that the steam entering through the steam conduit at passes into the
receiver a through the other conduit i and condenses in the receiver causing the
lubricant to flow in the reverse direction through the same conduits.
The lubricator may be emptied instantaneously by putting the conduits h and i
into communication. In this case the tap handle is turned down, when the steam
enters the conduit i and immediately forces out all the contents of the receiver.
In another form of lubricator shown in Figures 3 and 4 the receiver a is fed in
the same way by turning the tap handle c upwards whilst the lower handle d is
also turned upwards to shut off the entry of the steam. The receiver a then fills
itself
The lower part of the receiver a is closed by the lower tap or cock d which
establishes or intercepts communication with the steam entry e.
On the sides of the receiver a are arranged gauge glasses f' fixed in metal
boxes g' by soldering (see Figure 5).
To put the apparatus into action the tap handles c and d are turned horizontally,
the steam then rises into the receiver a through the conduits h and condenses,
causing the lubricant to rise and pass along the same path as the steam but in the
reverse direction. The lubricant is thus drawn with the steam into the slide valve
and from there into the cylinder in such manner that the steam being constantly
charged or mixed with small particles of lubricant all the parts work with ease and
freedom, and at the same time with great economy of the lubricating material.
By turning the handle of the lower cock d in a horizontal direction the conduits

page_text: h and i are put in communication by the channel k in the tap and the lubricator
rapidly empties itself.
Having now described the nature of the said Invention and in what manner the
same is to be performed I declare that I claim :-
The improvements in self-acting or automatic lubricators as hereinbefore
described and substantially as shown in the annexed drawings.
In witness whereof I the said Gustave Delettrez have hereunto set my hand
and seal this Twenty third day of April in the year of our Lord, One
thousand eight hundred and eighty three.
