I, JEAN HOCHGESAND, Mechanical Engineer, of 117 Boulevard de la Villette, Paris,
in the Republic of France, do hereby declare the nature of this invention to be as
follows:-
The present application relates to a lubricating apparatus having a constant level
and a multiple distribution, in which the supply, which is regulated at will, is
perfectly visible; the apparatus also permits of a distribution, to the various parts
of the machine to which is applied, of a certain regulated quantity of petroleum or
other analogous liquid for cleansing purposes.
In order that the invention may be readily understood I have represented in the
accompanying drawings an example of the method of carrying my invention into
effect.
Fig. 1 is an elevation of the apparatus.
Fig. 2 is a horizontal section on the line 1-2 of Fig 1.
Figs. 3 and 4 are two vertical transverse sections drawn respectively on the
lines 3-4 and 5-6 also of Fig. 1.
In all the figs. like letters of reference indicate the same parts.
My improved apparatus is composed in principle of a reservoir of any convenient
form and size comprising two compartments a b, the one a for the lubricant, the
other 6 for the liquid to be distributed to various parts of the machine where it is
desired to avoid clogging or incrustation.
The reservoir a is provided with a level indicating tube c and with a variable
number of drop feeders d, the supply from which is regulated at will; these drop
feeders communicate with chambers e, which may be vertical or horizontal according
to requirements and on which are branched the conduit pipes f intended to conduct
the oil to the parts to be lubricated.
The introduction of oil into the compartment a can be effected after the removal
of the stopper g by unscrewing.
The delivery of each drop feeder d is regulated by a rod terminated by a
swivelling handle h¹ which rests on a milled button i screwed to the upper part
of the oil reservoir; as soon as the delivery is regulated the position of this
button is fixed by means of a lock-nut j.
The regulating rod his constantly acted upon by a coiled spring k which tends
constantly to press it to its seat in such manner that it stops the flow of lubricant
as soon as the swivelling handle h is placed horizontally.
The milled button i is attached to a tube l, the interior diameter of which is
slightly larger than the diameter of the rod h, so as to be capable of receiving the
coiled spring and of leaving a certain play for the passage of air, which cannot
enter into the reservoir a except through the space comprised between this rod h
and the tube l, in such manner that the feed is only subjected to the influence of
the height comprised between the lower extremity of the tube l and the extremity of
the rod h.
The glass tube m intended to prevent dust from entering, and at the same to

page_text: allow the supply to be seen, rests at its lower part on a stopper n screwed on the
body of the apparatus and presenting a rectangular space n¹, in which engages the
key for screwing up or unscrewing the stopper.
In the interior of this latter are formed channels n2, which allow the oil to pass to
the interior of the chamber e.
The stopper n is covered with a cap o, as shown in Fig. 3.
This arrangement allows the stopper n to be screwed up so as to rigidly fix the
glass tube m.
Following this method of mounting, a glass tube m may be easily withdrawn by
simply unscrewing the stopper n and the cap o, without it being necessary to remove
the conduit pipes f.
The same arrangement may be applied to the upper part of the level indicating
tube c.
The chamber e encloses a valve p which, when the lubricator is applied for
example to a gas motor, prevents the entrance of gas into the body of the lubricator.
This valve is characterized by the special arrangement of its cylindro-conical
spring.
The rod p¹ of this valve has at its upper end a screw threaded part, on which is
wound the cylindrical portion of the spring, each spiral of which fits into the screw
threads of this rod.
This arrangement permits not only of assuring the preservation of the spring, but
also of regulating the same.
In effect, by turning the rod p in the direction of screwing, the spirals of the
spring will be compressed and consequently the strength of the spring will be
increased; on the contrary by turning in the reverse direction, the spring will be
distended and the latter will be rendered much more sensitive..
In order to allow the flow of the oil falling from the drop feeder d, an air supply q is
arranged in the interior of each of them; each channel q communicates with
the conduit q', which has connected with it two vertical tubes qq, each opening
into the upper part of the compartments a b.
The conduit pipes f connected with the different chambers e enable the lubricant
to be delivered to the various parts to be lubricated.
In order to enable these various parts to be cleaned at will, the tubes f may also
convey at will either petroleum or any other liquid answering the same purpose.
For this purpose the chambers e corresponding with these conduit tubes will
communicate, as shown in the drawings, with the interior of the reservoir b by
means of a canalisation r.
The supply of the petroleum will be regulated by a rod 8 terminated at its
upper part by a screw threaded part t screwing into the reservoir b and furnished
with a milled button..
This part t, which is hollow, is provided with different orifices opening into the
interior of the reservoir b and is closed by the stopper u.
The filling with petroleum is effected by unscrewing this stopper u, without
it being necessary to touch the regulating rod s.
My arrangement of lubricator therefore allows of lubricating and cleansing the
various parts of a machine and consequently may be applied with advantage to
petroleum motors, for then the different parts of the motor will be lubricated
during the working of the motor and when it stops all supply of lubricant may
be stopped and petroleum may be sent through the lubricator to clean all the parts.
It is well understood that my arrangement of lubricator may be constructed
in various forms and dimensions, and I reserve the right of modifying the
arrangements of the details according to the different applications.

I, JEAN HOCHGESAND, Mechanical Engineer, of 117 Boulevard de la Villette,
Paris, in the Republic of France, 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 present application relates to a lubricating apparatus having a constant level
and a multiple distribution, in which the supply is capable of regulation at will
and is perfectly visible; the apparatus also permits of a distribution, to the
various parts of the machine to which it is applied, of a certain adjustably
regulated quantity of petroleum or other analogous liquid for cleansing purposes.
In order that the invention may be readily understood I have represented in the
drawing accompanying my Provisional Specification and in the accompanying
drawing two methods of carrying my invention into effect.
Fig. 1 is an elevation of one form of the apparatus.
Fig. 2 is a horizontal section on the line 1-2 of Fig. 1.
Figures 3 and 4 are two vertical transverse sections drawn respectively on the
lines 3-4 and 5-6 also of Fig. 1. and Fig. 5 is a vertical section of another or
modified form of the apparatus.
In all the figures like letters of reference indicate the same parts.
My improved apparatus is composed, in principle, of a reservoir of any convenient
form and size, comprising two compartments a, b, the one a for the lubricant, the
other 6 for the liquid to be distributed to various parts of the machine where it is
desired to avoid clogging or incrustation.
The reservoir a is provided with a level indicating tube c and with a variable
number of drop feeders d, the supply from which is capable of regulation at will;
these drop feeders communicate with chambers e which may be vertical or horizontal
according to requirements and to which are connected the conduit pipes f intended to
conduct the oil to the parts to be lubricated.
The introduction of oil into the compartment a can be effected after the removal
of the stopper g by unscrewing.
The delivery of each drop feeder d is regulated by a rod h terminated by a
swivelling handle h¹ which rests on a milled button i screwed to the upper part of
the oil reservoir; as soon as the delivery is regulated, the position of this button is
fixed by means of a lock nut j.
The regulating rod h is acted upon by a coiled spring which tends constantly to
press it to its seat, in such manner that it stops the flow of lubricant, as soon as the
Swivelling handle h' is placed horizontally.
The milled button i is attached to a descending tube the interior diameter of
which is slightly larger than the diameter of the rod h, so as to be capable of
receiving the coiled spring k, and of leaving a certain play for the passage of air
which cannot enter the reservoir a except through the space comprised between this
rod h and the tube l, in such manner that the feed is only subjected to the influence
of the height comprised between the lower extremity of the tube and the extremity
of the rod h.
The glass tube m intended to prevent dust from entering and at the same time
to allow the supply to be seen, rests at its lower part on a stopper n screwed into the
body of the apparatus and provided with a rectangular space u¹, to receive the key
for screwing up or unscrewing the stopper.

page_text: In the interior of this latter are formed channels which atow the on to pass to
the interior of the chamber e.
The stopper n is covered with a cap o, as shown in Fig. 3.
This arrangement allows the stopper n to be screwed up so as to securely fix
the glass tube m.
By this method of mounting, a glass tube m may be easily withdrawn, by
simply unscrewing the stopper n and the cap o, without it being necessary to
remove the conduit pipes f.
The same arrangement may be applied. as shown to the upper part of the level
indicating tube c.
The chamber e encloses a valve p, which when the lubricator is applied for
example, to a gas motor, prevents the entrance of gas into the body of the
lubricator.
This valve is characterized by the special arrangement of its cylindro-conical
spring.
The rod p' of this valve has at its upper end a screw threaded part on which is
wound the cylindrical portion of the spring, each spiral of which fits into the screw
threads of this rod.
This arrangement permits not only of assuring the preservation of the spring
but also of regulating the same.
In effect, by turning the rod pl, in the direction for screwing up, the spirals of
the spring will be compressed and consequently the strength of the spring will be
increased; on the contrary by turning in the reverse direction, the spring will be
distended and the latter will be rendered much more sensitive.
In order to allow the flow of the oil falling from the drop feeders d, an air supply q is
arranged in the interior of each of them, each channel q communicates with the
conduit q¹ which has connected with it two vertical tubes qq, each opening into the
upper part of the compartments a, b.
The conduit pipes f connected with the different chambers e enable the lubricant
to be delivered to the various parts to be lubricated.
In order to enable these various parts to be cleaned at will the tubes f may also
convey at will, either petroleum or any other liquid answering the same purpose.
For this purpose the chambers e corresponding with these conduit tubes will
communicate as shown in the drawings, with the interior of the reservoir 6 by means
of a canalisation r.
The supply of the petroleum will be regulated by a rod s terminated at its upper
part by a screw threaded part t screwing into the reservoir and furnished with a
milled button i.
This part t which is hollow is provided with different orifices opening into the
interior of the reservoir b and is closed by the stopper u.
The filling with petroleum is effected by unscrewing this stopper u, without it
being necessary to touch the regulating rod s.
My arrangement of lubricator therefore allows of lubricating and cleansing the various
parts of a machine and consequently may be applied with advantage to petroleum
motors, for then the different parts of the inotor will be lubricated during the
working of the motor, and when it stops, all supply of lubricant may be stopped and
petroleum may be sent through the lubricator to clean all the parts.
In the modification shown at Fig. 5 the apparatus is provided with an independent
air supply for each drop feeder and with a removable compartment for containing
the petroleum or other cleansing fluid.
According to this modification the flow of oil, falling from the various drop feeders,
is ensured by a special air duct arranged in each of them and taking its supply of the
air from the atmosphere without any direct communication with the exterior.
For this purpose in front of each drop feeder there is provided in the body of the
apparatus a small channel 1 communicating externally with the atmosphere and
internally with the interior of a tube 2 rising to the upper part of the reservoir a and

page_text: opening into the interior of a second tube 3 closed at its upper end and terminating
at its lower end in the channel q.
In these conditions whatever may be the quantity delivered by a drop feeder, it
will have no influence on the working of the others and, further, the oil can never
run away through the air holes, because the space into which the oil falls does not
communicate directly with the exterior.
In order to facilitate the cleansing of the apparatus, the reservoir b containing the
petroleum or other cleasing liquid is rendered removable.
For this purpose, this reservoir b is fixed to a head 4 provided with a mouth piece 5
for the adinission of the petroleum and an ajutage 6 to which is attached the
canalization 7 which communicates with the chamber e.
The delivery of the petroleum or other cleansing liquid into this canalization is
regulated by a rod 8 screwing into the ajutage 6.
The head 4 fits into a rebate 7 formed in the thickness of the compartment a and
is held in position by the rod 8.
This rod, which is screwed into a boss formned for this purpose on the inner face of
the head 4, passes through the compartment a and has at its end a screw threaded
part on to which a nut 9 is screwed.
In these conditions, in order to remove the compartment b, it is only necessary to
unscrew the nut 9 and the union 10 which connects the tuber with the ajutage 6.
The reservoir 6 has an ajutage 11 which enables the air contained in the reservoir a
to act on the surface of the petroleum or other liquid, and thus permit of the flow
of the latter.
It will be well understood that my arrangements of lubricator may be constructed
in various forms and dimensions, and I reserve the right of modifying the arrange-
ments of the details according to the different applications.
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
1. In sight feed lubricators, the arrangement of apparatus for distributing to
various parts of a machine, either lubricant, or a liquid such for instance as petroleum,
capable of cleansing these parts and comprising two reservoirs a. b communicating
at will with various chambers e, upon which the different conduit tubes are fixed
substantially as herein set forth.

independent of each other, substantially as herein set forth.
5. In sight feed lubricators of the character herein described the arrangement of
valve with cylindro-conical coiled spring, substantially as herein set forth.
