PROVISIONAL SPECIFICATION.
An Improved Lubricator.
I, JOSEF WILDEMANN Jr. of Kronprinzen Ufer, Berlin, in the German Empire,
Merchant do hereby declare the nature of this invention to be as follows:-
This invention relates to a lubricator which is more especially adapted for use on
locomotives. It is designed to allow of the lubricant being distributed from one
central position, say that of the engine driver, to the several parts of the engine which
require lubrication, namely, the slide, cylinders, axles, air brake, etcetera.
It consists
in the combination of an oil presser or pump by which oil is drawn from a reservoir
and forced through passages 6tted with check valves into drop feed apparatus, in the
form of a casing within which is an oil receiver fitted with a piston cylinder. Both
the receiver and its inner cylinder are provided with orifices and the inner cylinder
also with a valve opening downwards against the resistance of a spring. According
to the position of the piston cylinder induced by the oil pressure the oil pumped from
the reservoir may either enter through the orifices of both parts simultaneously, or the
oil pressure may force down the piston cylinder so as to open the valve and allow the
oil to pass into it more freely, whence it passes through a small orifice to the part to
be lubricated.
The oil may also be supplied from the pump to the drop feed through a nozzlǝ
delivering into a pipe baving at the end a fine orifice, from which with the aid of
steam pressure it is caused to pass drop by drop, the pipe in connection with the
nozzle being placed within a casing so as to leave a vacant space between the
two.

COMPLETE SPECIFICATION.
An Improved Lubricator.
I, JOSEF WILDEMANN Jr. of Kronprinzen Ufer, Berlin, in the German Empire,
Merchant, 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 a lubricator which is more especially adapted for use ön
locomotives. It is designed to allow of the distribution of the lubricant from a central
position say, that of the engine driver-in necessary quantities as desired to the
several parts of the engine requiring lubrication, namely the slides, cylinders,
elcetera.
The invention consists substantially in the combination of an oil forcing apparatus
or pump, with a distributing cock or slide and oil drop feed appliance.
In the accompanying drawing Fig. 1 is a vertical section of the lubricating apparatus
of this invention with the oil drop feed appliance removed. Fig. 2 a section of the
part carrying the distributing cock and in which the oil passages in any desirable
number are formed. Fig. 3 a section of the oil drop feed appliance and Figs. 4 and 5
modifications thereof.
A is the oil reservoir, B a pump cylinder, C piston in connection through rod at c
with hand lever at D for working the same. The piston C may be fitted with a
suction valve. E is a cock for distributing the oil to the several passages F these
being provided with check valves f which also serve as pressure valves for the
Prins S11

page_text: pump. Gare tubes leading from passages F to a similar number of oil drop feed
appliances which are each fixed on or near the part it has to lubricate.
It will suffice to describe the apparatus with reference to a single oil drop feed
appliance. A tube G leads from a passage F into a vessel I, in which is fixed a small
hollow cylinder K at one end of which is formed the seating of a valve g.
Within the
cylinder K is a slide cylinder L. K is provided with orifices x, v, whilst L has
orifices w.
In the position shewn in Fig. 3 the oil coming from a tube G will charge the inside
of slide cylinder L and the end space between this and K. From I the oil will pass
gradually in the form of a drop feed through fine orifice y of valve g which is kopt
normally pressed against its seating by a spring between it and the bottom cover of
the vessel.
If it is desired to supply the part to be lubricated with more oil than passes through y
the hand pump is operated to supply oil to the particular tube G. By the pressure
thus occasioned in the space above the end of cylinder L this is pressed down so as to
open valve g against the resistance of the spring previously referred to, when the oil
pumped in will pass away through the opened valve, which afterwards closes again
the oil then passing as before in drops through fine orifice y.
In Fig. the valve g is somewhat modified.
In Fig. 5 the oil is forced through a nozzle g¹ into a cylinder H located within
vessel G whence it falls in drops through fine orifice y, the feed being much assisted
by the rising or diminishing steam pressure ruling at the time in vessel G¹. If the
quantity of oil passing through y is insufficient, so much of the same is forced through
the nozzle that it overflows from H into and out of the vessel G. In this case the
valve may be placed above in the manner shown in dotted lines but it has the same
effect as the other arrangements.
It is obvious that the plug of cock E must be so set by means of handle N that the
way of the same shall communicate with that one of the passages F into which oil is
to be forced.
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 1
claim is:
A lubricator for lubricating from a central position consisting of an oil reservoir,.
pump, distributing cock or slide in connection with oil passages fitted with valves
and in connection with tubes leading to the parts to be lubricated in combination
with means for the delivery of the lubricating oil generally in the form of a drop
by drop feed through the orifice of a valve (Figs. 3 and 4) pressed to its seating by a
spring but which upon increase of the oil supply is opened by reason of the oil
pressure; or through the orifice of a cylinder or vessel H (Fig. 5) when upon increase
of the oil supply the said vessel H overflows so as to deliver an increased quantity of
oil to the part to be lubricated, substantially as described and shewn.
