Improvement in Lubricators,
I, HERMANN AUGUST THEODOR GÖNNEL, Manufacturer of Vetschau in the
Province of Silesia and Kingdom of Prussia 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 :-
In the lubricators with glass oil-reservoir hitherto used for lubricating bearings
etc., the reservoir has the shape of a cylinder rigidly connected with the metal
parts of the apparatus.
These apparatus are not only very easily broken and on account of it not being
possible immediately to replace the broken glass cylinder by another, very dear,
but they also have the disadvantage, that in case of the glass breaking and no
other lubricator being at hand an interruption of the work must take place.
My new invention does away entirely with these drawbacks.
The apparatus is shown in two different forms in the Figures 1 and 2 of the-
annexed drawing.
It consists of a tube d containing the valve c, the opening of which can be
regulated by the valve-cone g situated at the lower end of a pin C, capable of being
screwed up and down in f.
The tube d is provided with a thread by means of which it is screwed into the
cover of the bearing.
It is furthermore, as will be seen from Figure 2 partly punctured at m in order.
to enable the falling of the drops to be observed.
The upper end of the tube is provided with an inner thread (Fig. 1) for the
reception of valve c. This valve is provided with a ring a. On the latter there
stands the body f, which serves to guide the pin C. On the outer side of fis
attached the catch i. This catch catches in the ratchet-wheel h, arranged on the
pin C for the purpose of accurately adjusting the valve. The upper end of the
pin C is either fitted with a knob k (Fig. 1) or with an eye 1 (Fig. 2) in order to.
make it possible for the pin to turn.
The piece made in this way is placed with the help of packing-rings b, n, (Fig. 2).
in the neck of any kind of bottle-shaped vessel, and forms with it an easily
regulated lubricator, which besides possesses the advantage of it being able to
observe the lubrication in a twofold manner, firstly by the falling of the oil in the-
bottle and then by the falling of the drops inside the perforated tube d.
As oil-vessel, as has been already stated, any kind of vessel may be used; thus
for instance one can use the ball-shaped bottle A₁, represented in Fig. 2, with
projection for putting a cover B, on, or an ordinary glass-bottle, A. (Fig. 1.) of
which the bottom has been knocked out. The latter is then also closed by a
cover B.
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. Lubricator, consisting of a bottle-shaped vessel without bottom of any kind
of shape and a part inserted in it and capable of being removed.
2. In the lubricator the arrangement of the inserted niece distinguished by the

page_text: perforated tube d and the adjustable valve cg connected with it in such a manner,
that by means of suitable packing-rings n b an oil-tight closing towards the outside
is made possible.
Dated this 12th day of May 1895.
