PROVISIONAL SPECIFICATION.
Improvements relating to Lubricators.
1, THEODOR KAHLE of 37 Sebastian Bach Strasse, Leipzig, in the Empire of
Germany Mechanical Engineer do hereby declare the nature of this invention to
be as follows:-
Heretofore lubricating cups in which the oil holder or cup, usually of glass, is
held upon a base by the pressure of a cover; the cover is connected to the base.
by a small tube rising in the centre of the cup, and the cup is filled through this
tube which has perforations in its walls and is usually closed by a small cap at the
upper end over the cover. .
The difficulty of pouring oil into such a small orifice causes often overflow and
waste of oil and a soiling of the machinery, and the object of the present invention
is to avoid this disadvantage.
For this purpose the invention consists in widening the upper part of the afore-
said tube into the shape of a funnel or hopper, that is to say usually of an inverted
cone, this part being in one with, or screwed on, or otherwise fixed on the aforesaid
tube which is made shorter so that the outer flange of the cone may rest and press
upon the upper edge of the cup and retain the latter in place without the
intervention of the cover.
The cone may be perforated. The cover being now no longer required to be
used to hold down the cup, may be wholly removable for filling the cup with oil
through the said inverted conical funnel.
The enlargement of orifice thus attained renders the lubricator more convenient
for filling without detracting from its capacity and the invention is applicable
to drop feed, wick feed or needle feed lubricators and generally to lubricator
oil cups.
Dated this 17th day of April 1894.

Improvements relating to Lubricators.
I, THEODOR KAHLE, of 37 Sebastian Bach Strasse, Leipzig, in the Empire of
Germany, Mechanical 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:—
Heretofore Jubricating cups in which the oil holder or cup, usually of glass, is
held upon a base-by the pressure of a cover, the cover is connected to the base by
a small tube rising in the centre of the cup, and the cup is filled through this tube
which has perforations in its walls and is usually closed by a small cap at the upper
end over the cover.
The difficulty of pouring oil into such a small orifice often causes overflow and
waste of oil and a soiling of the machinery and the object of the present invention
is to avoid this disadvantage.

page_text: For this purpose the invention consists in widening the upper part of the
aforesaid tube into the shape of a funnel or hopper, that is to say usually of an
inverted cone, this part being in one with, or screwed on, or otherwise fixed on the
aforesaid tube which is made shorter so that the outer flange of the cone may rest
and press upon the upper edge of the cup and retain the latter in place without the
intervention of the cover.
The cone may be perforated. The cover being now no longer required to be used
to hold down the cup, may be wholly removable for filling the cup with oil through
the said inverted conical funnel.
The enlargement of orifice thus attained renders the lubricator more convenient
for filling without detracting from its capacity and the invention is applicable
to drop feed, wick feed or needle feed lubricators and generally to lubricator
oil cups.
In the annexed drawings
Fig. 1 is a vertical section through a drop feed lubricator. Fig. 2 a similar
section through a wick feed lubricator.
Fig. 3 is a section through a pin or needle feed lubricator.
Fig. 4 shows for sake of comparison the known construction of lubricator which
this invention is designed to replace.
Fig. 5 is a plan view of Fig. 3 with the cover removed.
Fig. 6 is a plan view of Fig. 4 with the screw plug removed.
a is the cup, c the cover and d the base. Reference to Fig. 4 will indicate that
formerly the cup a was secured on the base by the counter-pressure between the
cover c and based due to uniting these parts by means of the tube b, which also
formed both inlet and outlet, the inlet being closed by plug or a suitable cap.
According to this invention the cover e fulfils no purpose of holding down the
cup a so that it may be loose or simply hinged or screwed on, the latter method
being indicated in the drawings. The tube is shortened to receive screwed on
its upper end the sleeve at the apex of the inverted cone b. This cone is of
sufficient diameter at its upper part to extend to the walls of the cup a over which
the flange on the cone engages. The cone may be perforated at o to permit oil
poured therein to easily enter the cup a
These holes serve also for passage of
the wick of wick feed lubricators as in Fig. 2. indicates holes in the pipe b'.
The cone and pipe it is obvious may also be made in one piece, and the shape
is not material so long as ample space is left within the cup a outside the parts or
part and the flange engages the upper edge of the cup a without intervention
of the cover c.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
A lubricator having for the fixing of its removable body a an interior tubular
part connected with the base and terminating above in a perforated Haring portion b
having a flange engaging over the body a, the whole being covered by the removable
cap e substantially as and for the purpose set forth.
Dated this 22nd day of January 1895.
