page_text: I, HENRY HAMELLE, of 21, Quay Valmy, Paris, in the. Republic of France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for lubricating with oil whereby one or more
tubes, as desired, for conducting the oil to the surface to be lubricated can be fed
with oil without loss.
According to the invention I provide a pump actuated by any suitable means
and immersed in a bath or reservoir of oil. The pump sucks in the oil from the
bath and forces it into a distributor from which branch the drop-tubes for dis-
tributing the oil, in predetermined quantities to the surfaces to be lubricated.
The distributor is also provided with a spring-controlled valve for returning the
excess of oil to the bath when the pressure, determined in advance by the tension
of the spring, is exceeded.
A suitable arrangement for carrying out my invention comprises a closed bath
or reservoir containing the lubricant and two pumps, the said pumps being
operated by a lever which is actuated in any suitable manner and is keyed upon
a spindle carrying arms connected by links to the pistons of the pumps.
The lubricant forced out from the two pumps passes through nozzles to a com- -
mon neck which conducts it to the distributor.
The lubricant contained in the pumping apparatus is heated by means of a
steam coil or the apparatus could be arranged with a double bottom. The lubri-
cant forced out by the pumps passes to the drop apparatus through a suitable
neck and then through a number of small passages the openings of which into
drop-tubes are adjusted by cones fitted to screws. The lubricant escapes drop by
drop through the drop-tubes into glass tubes filled with water and provided with
tubes which convey the lubricant to the surfaces to be oiled.
The collecting distributor is provided with a valve comprising a ball plugging
the orifice of the collector under the action of a spring, the tension of which is
adjusted in advance for a given pressure. When this pressure is exceeded from
any cause, for instance, by the closure of one or more of the drop-tubes the valve
opens and allows the excess of oil to return to the bath or reservoir through a
tube provided therefor until the pressure again becomes normal, this operation
proceeding without interfering with the feeding of the drop-tubes which have
remained open.
The collecting distributor is also provided with a tube in which steam is caused -
to circulate for heating the lubricant.

page_text: I, HENRY HAMELLE, of 21, Quay 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 ascertained in and
by the following statement: -
This invention relates to apparatus for lubricating with oil whereby one or more
tubes, as desired, for conducting the oil to the surfaces to be lubricated can be fed
with oil without loss.
According to the invention I provide a pump actuated by any suitable means
and immersed in a bath or reservoir of oil. The pump sucks in the oil from the
bath and forces it into a distributor from which branch the drop-tubes for dis-
tributing the oil in predetermined quantities to the surfaces to be lubricated.
The distributor is also provided with a spring controlled valve for returning the
excess of oil to the bath when the pressure, determined in advance by the tension
of the spring, is exceeded.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which
Figure 1 is an elevation of lubricating apparatus made according to my inven-
tion :
Figure 2 is a longitudinal section of the pumping apparatus:
Figure 3 is a transverse section; and,
Figure 4 is a plan thereof:
Figure 5 is a front elevation of the distributing device; and
Figure 6 a vertical section thereof.
The pumping apparatus comprises a closed bath or reservoir R containing the
lubricant and two pumps P, P¹ which may or may not be provided with pump
gear (preferably without) and are operated by a lever L which is actuated in any
suitable manner. This lever L is keyed upon a spindle O carrying arms & con-
nected by links J J to the pistons of the pumps P, P¹.
The lubricant forced out from the two pumps passes through nozzles a, a¹ to
the common neck c which conducts it to the distributor A.
The lubricant contained in the pumping apparatus is heated by means of a
steam coil V; or the apparatus could be arranged with a double bottom. The
lubricant forced out by the pumps passes to the drop apparatus A through a neck d
and then, through the small passages e, the openings of which into the drop-
tubes g, g are adjusted by cones f fitted to screws . The lubricant escapes drop
by drop through the drop-tubes into the glass tubes K which are filled with
water and provided with necks adapted to place them in connection with the sur-
faces to be lubricated.
The collecting distributor is provided with a valve comprising a ball h plugging
the orifice i of the collector under the action of the spring, the tension of which
is adjusted in advance for a given pressure. When this pressure is exceeded from
any cause, for instance, by the closure of one or more of the drop-tubes the valve h
opens and allows the excess of oil to return to the bath or reservoir R through the
tube until the pressure again becomes normal, this operation proceeding without
interfering with the feeding of the drop-tubes which have remained open.
The collecting distributor is also provided with a tube Q in which steam is
caused to circulate for heating the lubricant.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. Lubricating apparatus comprising a pump arranged to suck in oil from a
reservoir and force it into a collecting distributor provided with drop-tubes and
with a valve enabling the oil to flow back to the reservoir when a predetermined
pressure is exceeded in the collector, substantially as described.
2. In apparatus of the kind described in Claim 1 heating the vessel containing
the pumps either by means of a steam coil immersed in the lubricant or by means
of a double bottom as described.
3. In apparatus of the kind described in Claim 1 heating the collecting dis-
tributor by the circulation of steam, substantially as described.
4. The combination and arrangement of parts forming the improved lubricating
apparatus hereinbefore described and illustrated in the accompanying drawing.
