COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, Alfred Lutze, of No. 58, Emilienstrasse, Halle on the Saale, in the Empire
of Germany, Manufacturer, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
The present invention consists of a lubricator which is particularly adapted for
use in connection with receptacles containing fluid pressure, steam, gas or air
under pressure, such as steam chests, steam cylinders and the like, the construction
of the lubricator being such that a compensation of pressure is attained all round
the oil as soon as the cock leading to the pressure receptacle is opened, so that the
lubricating material falls by gravity into the said receptacle.
In order to render the present specification easily intelligible reference is had
to the accompanying drawing in which similar letters of reference denote similar
parts throughout the several views:-
Fig. 1 is a vertical section through the lubricator, Fig. 2 a horizontal section
on line 0-0 of Figure 1 and Fig. 3 a similar section on line P-P of Figure 1.
According to the invention the outer receptacle or housing A is air tightly
closed at the top, and fitted with a tubular outlet opening B at the bottom, the
said tubular extension being provided with a stop cock as shown. This tubular
extension is provided with a glass tube H at some suitable part, so that the
Within the
passage of the oil down through the tube may be observed.
housing A is supported on suitable feet, an oil reservoir G, open at the top and
having a fine oil outlet tube or nozzle Fat the bottom, having its lower end
flared at L for a purpose herein after set forth. The tube F is in communication
with the interior of the reservoir G by means of small lateral openings as shown.
The top of the housing A is provided with an oil inlet, which may be closed by a
plug J, through which extends a stem K ending in a conical valve adapted to
close on to the top of the outlet tube F below the lateral openings from the same
to the interior of the reservoir G. The sleeve into which the plug J is screwed
extends downwardly somewhat into the top of the receptacle or reservoir G so that
in filling, the same it may not he overfilled and the space between its outer walls
and the housing A filled up with oil. In filling the reservoir with oil, the latter
should not be allowed to rise above the lower edge of the plug flange, and then
the reservoir G will not be overfilled. The flared lower edge L of the outlet F
serves to keep the water of condensation running down the walls of the housing,
from the oil outlet.
The device operates in the following manner:
Assuming it to be screwed to a steam chest or steam or other cylinder, as soon
as the stop cock is opened, the fluid pressure in the said cylinder encircles entirely
the oil reservoir G having free access to all sides of the same, and thus equal
pressure existing all around the oil reservoir G and also in the receptacle into
which the oil is to be fed, on raising the valve K, the oil or other lubricating
material will fall by gravity into the said receptacle.

page_text: The valve K serves to regulate the quantity of lubricating material allowed to
flow to the cylinder and the same may be adjusted to any desired position by
means of its screw thread, fitting a sleeve arranged at the lower part of the
reservoir G above the outlet tube F.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1: In a lubricator for use in connection with receptacles containing fluid
pressure, the combination of a housing A having lower tubular extension with
stop cock, an oil receptacle therein open at the top and having oil outlet at the
bottom with regulating valve therein, a space being left all round the said oil
reservoir between it and the interior of the housing A, in the manner and for
the purpose substantially as described.
2: In a lubricator of the class covered by Claim 1, the combination of an inlet
opening for the lubricating material, to the housing A, said opening having an
annular downwardly extending flange, adapted to extend into the top of the oil
reservoir G, in the manner and for the purpose substantially as described.
3: In a lubricator, the construction and arrangement of parts in the manner
substantially as described and illustrated in the accompanying drawings and for
the purpose set forth.
