Improvements in Lubricators.
I, FERDINAND BOSSHARDT of the firm of F. Bosshardt & Co., of 4, Corporation
Street, Manchester in the County of Lancaster, Engineer and Patent Agent, do
hereby declare the nature of this invention which has been communicated to me from
abroad by William Lauke, of 30 Boulevard St. Germain, Paris, France, to be as
follows
This invention relates to improvements in lubricators used for oiling parts of
machinery and has for its object to keep the oil from becoming solid, in cold or frosty
weather.
It consists in the employment of two holders of equal capacity one being filled
with a solution of common salt and the other with lubricating material.
Each one of these holders is provided with one or more sight glasses respectively
serving to indicate when empty of the solution of common salt, as well as to register
the amount of lubricating material drawn up.
These two holders are in connection with each other by means of a pipe through
which the solution of common salt is drawn by means of a pump connected therewith,
from the respective holder, and mixing with the lubricating material, is forced to the
part to be lubricated.
The said pump may be actuated either from a lever or a pulley.

nature of this invention, which has been communicated to me from abroad by
William Lauke of 30 Boulevard St. Germain, Paris, France, 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 improvements in lubricators used for oiling parts of
machinery and has for its object to keep the oil from becoming solid, in cold or frosty
weather.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference, similar
letters indicating like parts throughout the figures.
•
Fig. 1 is a sectional side elevation and Fig. 2 a plan of a part of the same.
The holder A is provided with one or more sight glasses, and filled with lubri-
cating matter, which is introduced by means of the orifice or pipe m, the tap d, and
the latter being in communication with the reservoir B and a pump.
pipe c,
The said reservoir B is filled with a solution of common salt which will not freeze,
and the pump actuated by means of a cord pulley u, or lever.
a, is a suction valve, and ba back pressure valve. sa pipe or valve which admits of
a maximum pressure of 15 atmospheres.
The holder's A and B are of equal contents, the displacement of the lubricating
matter taking place in proportion to the diminution of the liquid.
The partition o of the holder B is partly transparent and registers the progressive
consumption of the lubricating matter.
When all the lubricating matter has left the holder A, the pump draws in the fresh
air which rises in the holder A, and the pipe e and also in the sight glasses h, and
forms bubbles.
These bubbles are clearly distinguishable from the oil bubbles and show when it is
necessary to put fresh lubricating matter into the holder A.
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 :-
-
The combination of holder A containing lubricating matter with a holder B of
equal contents, and a pump for the purpose of forcing the lubricating matter gradually
towards the parts to be lubricated, drawing a solution of common salt from the
holder B & pushing the same towards the holder A in such a manner that the
complete emptying of the holder B can be observed in the sight glasses h, by
means of the air bubbles which rise therein, instead of oil drops, substantially as
set forth.
Dated this 12th day of September 1887.
