page_text: LETTERS PATENT to Albert Stanislas Fleutelot, of Boulevard de Strasbourg,
No. 23, Commercial Agent, for the Invention of "AN IMPROVED APPARATUS
FOR OILING OR GREASING AXLES, PISTONS, CRANKS, SLIDES, AND OTHER
MOTIVE PARTS OF MACHINERY."
Sealed the 15th November 1878, and dated the 11th June 1878.
PROVISIONAL SPECIFICATION left by the said Albert Stanislas Fleutelot
at the Office of the Commissioners of Patents on the 11th June 1878.
ALBERT STANISLAS FLEUTELOT, of Boulevard de Strasbourg, No. 23, Commercial
Agent. "AN IMPROVED APPARATUS FOR OILING OR GREASING AXLES, PISTONS,
CRANKS, SLIDES, AND OTHER MOTIVE PARTS OF MACHINERY."
The system of lubricator which forms the object of my Invention is arranged so
as to determine or regulate the introduction of the oil into the parts to be lubricated,
and especially into cylinders, slides, and steam ports.
The cock which regulates the flow of the oil is provided with a differential annular
groove of gradually diminishing section so that it is exceedingly easy to regulate
the lubrication at will.
A. controlling box is placed between the oil reservoir and the ejector tube for the
purpose of examination of the working of the apparatus, which may be arranged
beneath the controlling box either by a valve joint or by a steam injector ensuring
the flow of the oil.
I will now describe two arrangements of my lubricating apparatus.
According to the first arrangement it is composed of a reservoir closed by a screw
plug pierced with an air hole, which is left open whilst at work. A top basin
surrounding the reservoir is provided with holes in the bottom for lubricating when
at work. I employ a level indicator for estimating the quantity of oil remaining
in the reservoir, composed of two floating balls, rods, or circular pieces of light
material, such as cork, wood, or hollow metal joined together by a thread; one of
these balls is in the interior, and floats on the surface of the oil, the other is outside,

The extreme points of the scale correspond to the bottom of the reservoir and the
maximum height of the oil. The oil descends from the reservoir by a conduit to
the box of a cock, which latter is provided with a differential annular groove with
variable section both in depth and in width, by which the flow of oil may be
regulated at will and within extensive limits. The oil then falls to the bottom of a
lower chamber, which has two pieces of glass at the sides, held in place by screw;
plugs and washers of india-rubber, felt, or other material are placed against the
openings for the glass to rest upon, thus forming a hermetical joint. This visiting
box allows the action of the apparatus to be controlled.
The bottom of the controlling box is formed of a double screw plug, which is
fixed to the cylinder or slide box to be lubricated.
Above the oil outlet hole is a perforated grating or plate covered over with
cotton or other material, and a little bell-shaped piece and a valve slide freely on a
rod, the pressure of the steam raises the bell, causes the rod and the valve to ascend,
and allows the oil to escape through the orifice provided for it.
The second arrangement differs from the preceding in the lower plug; this
plug is pierced with two conduits; one of these conduits being larger the pressure
of steam in this tube drives off the steam which may have penetrated into the
smaller conduit, producing through a bent tube with tapered end a real injection
of steam. The oil drawn or sucked in enters a chamber, and thence passes into
the cylinder, carried through by the steam in the smaller tube.
A piece of cotton, wool, sponge, or other material is placed in the chamber for the
purpose of avoiding the inconvenience of the entrance of air by suction.
The cock may be formed of two parts, with a screw between the differential
groove cock and the controlling box, so that the upper part only may, if necessary,
be adapted to a plumber block bearing or other part requiring lubrication.

"
ALBERT STANISLAS FLEUTELOT, of Boulevard de Strasbourg, No. 23, Commercial
Agent. AN IMPROVED APPARATUS FOR OILING OR GREASING AXLES, PISTONS,
CRANKS, SLIDES, AND OTHER MOTIVE PARTS OF MACHINERY."
The system of lubricator which forms the object of my Invention is arranged so
as to determine or regulate the introduction of the oil, especially into cylinders,
slide valve boxes, steam ports, and all steam or air capacities requiring lubrication.
In the case of a cylinder oil will be introduced at each stroke of the piston, and in
the case of a slide valve box at each movement of the slide.
The cock which regulates the flow of the oil is provided with a differential
auxiliary groove of gradually diminishing section, so that it is exceedingly easy to
regulate the lubrication at will.
A control box is placed between the oil reservoir and the part to be lubricated
for the purpose of examination of the working of the apparatus. At the entrance
of the channel leading from this control box to the apparatus for lubricating
cylinders or slide valve boxes, is interposed a small movable piece, valve, or clack,
closing the orifice of the discharge pipe and opening it at each stroke of the piston,
or at each movement of the slide under the influence of the vacuum or of pressure
produced in those parts.
I will now describe, with reference to the annexed Drawing, my apparatus
devised for lubricating a cylinder or a slide valve box at the moment when these are
in communication with the exhaust, Figure 1 being a vertical section; and Figure
2, a vertical section of the cock showing the differential groove permitting the
regulation of the introduction of the oil. It is composed of a reservoir A, in the
form of a basin or well closed by a screw plug a; this latter is pierced with an air
hole b, which is left open whilst at work.
I employ a level indicator for ascertaining the quantity of oil remaining in the
reservoir, composed of two floating balls, rods, or circular pieces e, of light material,
such as cork, wood, or hollow metal joined together by a thread f; one of these
balls is in the interior, and floats on the surface of the oil, the other is outside, and
ascends or descends in front of the graduated scale 3, marked on the reservoir.
The extreme points of the scale correspond respectively to the bottom of the reser-
voir and the maximum height of the oil. The oil descends from the reservoir A by
the conduit to the box B of the cock C. The cock (shown in elevation, Figure
1, and cross section, Figure 2) is provided with a differential annular groover, of
variable section, both in depth and in width, by which the flow of oil may be
regulated at will, and within extensive limits. The oil then falls by the tube i to
the bottom of the chamber D, which chamber has two pieces of glass E, held in
place by screw caps ; and washers q, of india-rubber, felt, or other material, are
placed against the openings for the glass to rest upon, forming a hermetical joint.
This visiting box allows the action of the apparatus to be controlled.
The control box D is screwed on to a double screw plug F, which is fixed to the
cylinder, or the slide valve box to be lubricated. A small valve 8 is placed in a
space reserved between the bottom of the box D and the piece F.
The steam from the cylinder or the slide presses the valve 8 against the discharge
orifice o of the oil. As regards each stroke of the piston the lower face of tho
valves is in communication with that part of the cylinder where the exhaust takes
place; the valve s falls by its own weight; the atmospheric pressure acting through
the holes & causes the oil to flow by the orifice o. It may then pass by the grooves
u, of the valve & coming into contact with the parts to be lubricated by the
orifice y.

page_text: And having now described the nature of my said Invention, and in what manner
the same is to be performed I declare that I claim,-
First. The arrangement of the cock-key with annular differential groove of
decreasing section, as shown, for regulating the introduction of the oil, as herein-
before described.
Secondly. The control box with lateral plates of glass, as herein-before described,
and as shown.
Thirdly. The level indicator when employed in combination with my apparatus
for the purposes set forth.
Fourthly. The arrangement of the valve for the regulation of the flow of oil
according to the conditions described.
Fifthly. The general arrangement and combination of parts constituting the
improved lubricator, as herein-before described and shown.
In witness whereof, I, the said Albert Stanislas Fleutelot, have hereunto
set my hand and seal, this Thirteenth day of November, One thousand
eight hundred and seventy-eight.
