Improvements in and connected with Lubricators for Motor Vehicles
and High Speed Machines.
I, HENRY HAMELLE, of 21, Quai Valmy, Paris, in the Republic of France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and connected with lubricators for
motor vehicles and high speed machines.
Amongst the improvements effected in mechanical construction one of the
most recent consists in the distribution of lubricants by means of a single device,
to the different parts of a machine which require oiling. Hitherto such apparatus
has been more particularly applied to steam engines, steam being employed as the
main agent or means for forcing the oil into the feed tubes.
Now my invention comprises improvements in apparatus of this class the object
being to provide simple and strong apparatus which can be easily regulated.
In carrying out the invention I provide a rectangular casing filled with oil
and hermetically closed. To the outside of the casing there are fitted the oil
outlets or exits and a grooved pulley serving to operate the interior mechanism.
This pulley is rotated from the machine through the medium of a cord of leather,
gut or other suitable material.
Each of the oil outlets is supplied by a separate pump, the cylinder of which
is provided at its upper part with a moulded leather and at its lower part with
a valve. The upper part serves as a piston guide and is formed with slots and
with two lateral holes which serve as the oil inlets; the lower part of the guide
holds the leather upon the pump body and at the same time secures the pump
in position. The valve box also serves as a fixing nut and its free end is
extended for receiving a nut and socket designed to hold the oil distributing tube.
The piston is provided at its upper end with a cross-piece limiting its movement
and sliding freely in the slotted part of the guide, the said cross-piece being
acted upon by a spring which maintains the piston at the top of its stroke and
gives the oil free access to the pump body. A metal gauze jacket enclosing the
guide prevents impurities passing into the pump.
The spindle or shaft which is rotated by the grooved pulley revolves an endless
screw gearing with a toothed wheel keyed to an eccentric shaft which transmits
its movement through the medium of small connecting rods to as many levers as
there are pumps. Each of these levers is provided with a screw having a notched
head, and the lower end of which at each revolution of the main shaft comes in
contact with the piston corresponding to it. The movement of each screw is
limited when unscrewed to its full extent the maximum supply is obtained,
when screwed up to its greatest extent, minimum supply is obtained, the inter-
mediate positions being obtainable by means of a spring which can engage as
desired in any one of the notches of the head.
For packing the opening in the casing through which the main spindle passes
I advantageously provide two washers of felt which are held in position by a

page_text: ring and an oval flange, arranged so that the washers press against the two faces
of a collar or flange on the said spindle thereby preventing all loss of oil.
The operation of the apparatus is extremely simple. The main spindle
operates the eccentric shaft which in its turn actuates the levers, the movement
of which is partially transmitted by the screw stops, according to their position,
to the heads of the pistons. During their downward stroke, the stops push the
pistons downwards which in their turn force the oil through each escape valve.
During their upward stroke, the pistons, which are forced back by their
springs, return to the end of their stroke and oil again flows into the pump
cylinder.
It is to be noted that the lubricator commences to operate as soon as the
vehicle starts and that it ceases to operate, when the vehicle stops, without the
intervention of, the attendant.
Although the lubricator has been designed without a drop or sight-feed (for
its special application to motor vehicles) its operation would be in no wise inter-
fered with by the combination therewith of this device which can be independent
of it or form a part thereof.

Improvements in and connected with Lubricators for Motor Vehicles
and High Speed Machines.
I, HENRY HAMELLE, of 21, Quai Valmy, Paris, in the Republic of France,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertamed in and
by the following statement:-
-
This invention relates to improvements in and connected with lubricators for
motor vehicles and high speed machines.
Amongst the improvements effected in mechanical construction one of the
most recent consists in the distribution of lubricants, by means of a single device,
to the different parts of a machine which require oiling. Hitherto such apparatus
has been more particularly applied to steam engines, steam being employed as the
main agent or means for forcing the oil into the feed tubes.
Now my invention comprises improvements in apparatus of this class the object
being to provide simple and strong apparatus which can be easily regulated.
In the accompanying drawing:
Figure 1 is a sectional elevation of apparatus made according to the invention;
Figure 2 is a section on the line 2-2 Figure 1:
Figure 3 is a partial plan; and,
Figures 4 and 5 are views of details.
In carrying out the invention I provide a rectangular casing Z filled with oil
and hermetically closed. To the outside of the casing there are fitted the oil
outlets or exits h and a grooved pulley P serving to operate the interior
mechanism. This pulley is rotated from the machine through the medium of a
cord of leather, gut or other suitable material.
Each of the oil outlets is supplied by a separate pump M, N, K, the cylinder N
of which is provided at its upper part. with a moulded leather a and at its lower
part with a valve c. The upper part M. serves as a piston guide and is formed

page_text: with slots b, b and with two lateral holes d which serve as the oil inlets: the
lower part of the guide M holds the leather upon the pump body N and at the
same time secures the pump in position. The valve box F also serves as a fixing
nut and its free end is extended for receiving a nut and socket designed to hold
the oil distributing tube h. The piston K is provided at its upper end with a
cross-piece limiting its movement and sliding freely in the slotted parts 6 of
the guide, the said cross-piece k being acted upon by a spring which maintains
the piston K at the top of its stroke and gives the oil free access to the pump
body N. A wire gauze jacket t enclosing the guide M prevents impurities passing
into the pump.
The spindle or shaft A which is rotated by the grooved pulley P revolves an
endless screw B gearing with a toothed wheel C keyed to an eccentric shaft 1)
which transmits its movement, through the medium of small connecting rods E
to as many levers H as there are pumps. Each of these levers H is provided
with a screw J having a notched head a, and the lower end of which at each
revolution of the shaft comes in contact with the piston K corresponding to
it. The movement of each screw J is limited; when unscrewed to its full extent
the maximum supply is obtained, when screwed up to its greatest extent, the
minimum supply is obtained, the intermediate positions being obtainable by
means of a spring g which can engage as desired in any one of the notches of
the head r.
For packing the opening in the casing through which the main spindle A
passes I advantageously provide two washers S, S₁ (Figure 4) of felt which are
held in position by a ring R and an oval flange T, arranged so that the washers
press against the two faces of a collar or flange on the said spindle A thereby
preventing all loss of oil.
The main spindle A
The operation of the apparatus is extremely simple.
operates the eccentric shaft I which in its turn actuates the levers H. the move-
ment of which is partially transmitted by the screw stops J, according to their
position, to the heads of the pistons K. During their downward stroke, the
stops push the pistons K downwards which in their turn force the oil through
each escape valve.
During their upward stroke, the pistons, which are forced back by their
springs, return to the end of their stroke and oil again flows into the pump
cylinders.
It is to be noted that the lubricator commences to operate as soon as the
vehicle starts and that it ceases to operate, when the vehicle stops, without the
intervention of the attendant.
Although the lubricator has been designed without a drop or sight-feed (for
its special application to motor vehicles) its operation would be in no wise inter-
fered with by the combination therewith of this device which can be independent
of it or form a part thereof.
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: -
Apparatus for lubricating motor vehicles, high speed machines etc., combined,
arranged and operating substantially as hereinbefore described and illustrated in
the accompanying drawing.
