Improvements in Lubricators for Steam Cylinders and the like.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
sex, Patent Agent, do hereby declare the nature of this invention and in what manner
the same is to be performed, as communicated to me by Franz Siegel, of Altwasser,
District of Waldenburg, Silesia, Manufacturer, to be particularly described and
ascertained in and by the following statement:-
Lubricators as hitherto used of the kind which are provided with an oil reservoir
between the oil-inlet cock and the steam-cut-off, have but one passage for the oil
which consequently flows very slowly into the reservoir, when this is to be filled.
Also when the steam-cock leaks and steam enters the reservoir the flow of the oil
thereinto ceases entirely. Moreover, when the oil is to be introduced into the
steam cylinder or the like, only a small quantity passes thereinto because of the
steam pressure. The lubrication, therefore, is very difficult and the loss of oil is
considerable.
The object of the present invention is to avoid these inconveniences by pro-
viding the two cocks with double bores.
The invention is illustrated in the accompanying drawing.
The oil-inlet-cock a and the steam-cock bare each provided with double bores.
One of these bores corresponds to the ordinary passages for filling the reservoir c
with oil and for introducing same into the steam cylinder or the like.
The other bore of the upper cock corresponds to a special passage e, which
serves the purpose of putting the reservoir c in communication with the surround-
ing atmosphere, when the reservoir is to be filled. Also in the case of leaking of
the steam-cock b the steam entering passes off by this passage e.
The second bore of the lower cock 6 corresponds to a passage d in which is fitted
a small pipe forming a prolongation of said passage, and which puts the steam
cylinder or the like into communication with the upper part of the reservoir c.
Therefore when the steam-cock b is opened, the reservoir c is under the pressure of
the steam in the steam cylinder or the like and consequently the oil can flow into
the cylinder or the like without any difficulty.
Of course, this device may be employed not only for cylinders, but for any reser-
voir under pressure. It may be of any suitable material, the reservoir c being
preferably of glass.
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:-
A lubricator for steam-cylinders and the like comprising an oil-inlet-cock a and
a steam-cock beach provided with double bores, in order on the one hand to put
the reservoir c between the two cocks by a special passage e into communication
with the surrounding atmosphere, when the reservoir is to be filled, and in case of
leakage to allow the steam to escape by this passage, and on the other hand to

substantially as described and illustrated in the accompanying drawings.
