Improvements in or relating to Oiling Apparatus.
I, ALEX FRIEDMANN, of Am Tabor 6, Vienna, in the Empire of Austria,
Engineer, 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: -
Existing oiling apparatus such as Mollerups and others, do not supply oil to
several oiling chambers or parts to be oiled having different pressures prevailing
in them because the lubricant pressed out of the apparatus takes the course where
it finds the least resistance, consequently the chamber which is under higher
Where it is desirable for instance to oil the
pressure does not receive any oil.
steam cylinder and the cover on the exhaust, double apparatus is used with two
oil cylinders entirely separated one from the other.
The present invention relates to an improved oiling apparatus which renders
it possible to supply a number of chambers with oil by means of single oiling press
or pump, each of these chambers receives a fixed quantity of oil independent from
the pressure in the same.
The annexed drawing shows the apparatus in connection with an oiling press,
Figs. 14 and with an oil pump (Fig. 5-13). In Fig. 14 is the plunger piston
of an oiling press by the descending movement of which the oil contained in the
cylinder a leaves through a passing from there into the chamber wherein a
valve is arranged on the shaft c, this valve is arranged so that it can slide on
a square head of the shaft c and is revolved by the movement of the same; this
shaft c works the plunger piston.
The valve is held down on its valve face by a spring e and is provided, as
shown in Fig. 4 with an opening f in form of a slot which passes during the
rotary movement of the valve over the openings g g² 9° g³g g² arranged in the
valve face shown in Fig. 3 which is a section on the line A B of Fig. 1 whereby
the channels hhhh³°³ which are connected to these openings, are respectively
The distance between the several

openings must be such that one opening only at a time is in connection with
the valve room bby means of the slot f but such distance must not be greater
than the breadth of slot f so that there always remains an exit for the oil forced
out by the plunger piston, otherwise the oil cylinder or the valve box might burst.
According to the distance of the openings gg from the turning point of the valve
or according to their size more or less oil goes through these openings into the
respective pipes h to h³.
In Fig. 5 instead of an oiling press an oil pump is shown provided with the
distributing valve. The valve d is here similarly mounted on shaft c which drives
the piston a by means of the eccentric k represented in Fig. 6 in section which
is taken on the line EF of Fig. 5. The valve is also provided with a slot f
Fig. 7.
By the arrangement of the valve d it is independent of any possible irregularity
of movement caused by wear or other causes of the shaft c and is always held flat

page_text: The valve face (shown in Fig. 8 in section on the line CD of Fig. 5) is provided
in this case with an opening g in the form of an arc of nearly 180° communicating
with the oil vessel by the pipe h. During the ascending movement of the
piston a the slot f slides upon the opening thus putting the valve chamber b
into communication with the oil vessel 7 so that the oil can pass under the stroke
of the piston. When the piston descends the oil is forced through the channel a³
into the valve room band from there in the manner already mentioned through
the openings g¹g²g and channels h² successively, into the chambers or parts
to be oiled.
The Figs. 9, 10, 11 and 12 show the respective positions of the sliding valve
during the eccentric positions 1, 2, 3, 4 represented in Fig. 14. The bearing face
for the valve need not be flat but can as shown in Fig. 13 be ball or cone shaped.
Instead of the rotary valve described a flat valve shown in Fig. 15 can be used
which is worked by an eccentric p arranged on the shaft c giving a to and fro
movement to the valve.
The eccentric arranged at a right angle to the eccentric driving the plunger
piston moves the slot r of the valve during the ascending movement of the plunger
across the oil entrance opening g and during its descending movement the slot l
across the outlet opening g' of which several can be arranged in succession.
Possibly only one slot need be used as represented in Fig. 16 but then g¹ must be
arranged beside g.
This form of construction gives the desired purpose in a more difficult and less
advisable manner and is only mentioned for more fully explaining the principle
of the invention. If the oil pump is used in engines and other machines working
under high steam pressure, for oiling the valves or pistons it is advisable to
connect the oil vessel by a pipe m (Fig. 5) with the steam chamber of the boiler
or the piston box in order to give a high pressure in l. By this means any loose
ness of the sliding valve d does not hinder the oil distribution because the
differences of pressure between the parts principally to be oiled (as piston box
cylinder) and the oil vessel is thereby not so great as when the oil of the pump is
not delivered under pressure.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
1. An improved oiling apparatus enabling the delivery of any quantity of oil
independent from the pressure in the chambers to be oiled by means on only one
oiling press, or oil pump in which a sliding valve d provided with an opening f
is arranged displaceably but not turnably on the shaft c driving the plunger a
by the rotary movement of which always one of the openings g g³ g² g³g' g² arranged
one beside the other in the valve face is put into connection with the chamber b
and thereby with the cylinder a of the oiling press or oil pump.
2. A form of construction of the improved oiling apparatus described in Claim 1
for machines or engines working at a high steam pressure in which an oil vessel
connected with the oiling apparatus is put into communication with the steam
chamber of the machine or a boiler.
