ADOLPHE MICHAEL LEVY Mining engineer 37 Bassett Road Ladbroke Grove
Road London W. in the County of Middlesex 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:-
The invention has for it's object, a new system of automatic lubricator, consuming
solid or semi liquid grease, and applicable to connecting rod bearings, excentric
collars, and in general, to all such parts of machines, in which, the lubricator
participates in a movement of rotation, or of oscillation.
And, so that my invention should be thoroughly understood, I will refer to the
annexed sheet of drawings, in which can be seen, a plan and a vertical section of the
apparatus.
The drawings are simply chosen as examples, to show the construction of the
apparatus. It may vary in shape so as to suit any special application.
M is a plan of part of the connecting rod of a locomotive;
N is a vertical section by the line OP;
L is a section by the line Q R.
24 is the cover of the vessel containing the grease.
25 is a movable plug, for introducing the grease into the reservoir; 28 is a screw
for regulating the flow of lubricant, according to it's state of liquidity, which may be
variable, with the temperature of the atmosphere, and the velocity communicated to
the apparatus; this screw has a conical point, preventing the lubricant from passing
through the opposite holes, and guiding it, so that it should descend by the tube 29
down to the axle, or bearing, which is to be lubricated: 30 is a lock nut, for securing
the screw in an invariable position, when adjusted for the delivery of the required
quantity of grease. The action of the lubricator, is entirely automatic and will be
easily understood.

page_text: It begins to operate, as soon as the engine, to which it is attached, is set in motion.
As the crank of the locomotive revolves, the grease is thrown by the centrifugal
impetus, against the cover 24. The inside surface of this cover, is concave, so that
the lubricant is forced up to it's highest part, and is thus made to flow through the
small apertures 27 drilled in the sides of the tube, and which may be circular, oval or
rectangular, at will.
As soon as the engine is brought to a standstill, the flow of lubricant ceases.
The reservoir has sufficient capacity, to enable an engine to run for ten days,
without requiring a fresh supply of lubricant.
The shape and size of the apparatus, as well as the metal, of which it is made, may
he varied, as also the composition of the grease or oil used.
My invention consists in the combination of the improvements described above,
whether they are entirely or only partly carried out in the actual application.
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 :-
1st) The hemispherical shape given to the cover 24 of grease reservoir, having for
it's object to force the lubricant towards the centre of cover, and against the
porforated tube.
2d) The openings 27 drilled in the central tube.
3d) The conical screw, for regulating the flow of grease, and preventing it from
passing through the hole on the opposite side, by guiding it towards the axis of the
tube.
4th) The movable plug 25, which allows the reservoir to be refilled, without
disturbing the adjustment of the screw.
5th) The combination of the whole of the above improvements.
