Improvements in Means for Lubricating Bearings.
I, CARL DIETRICH, of 245, Bahnhofstrasse, Elsterwerda, in the Empire of
Germany, Manufacturer, 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:-
-
My invention relates to bearings and has for its object to provide a regular and
efficient lubrication of the surfaces, in a bearing, and consists essentially of an
endless chain or its equivalent hung upon the shaft or rotating part within a
chamber which chain is caused by the rotation of the shaft or part upon which it
is applied, to move continuously and so take up the lubricant which is deposited
in the lower part of the chamber and is applied thereby to the surface of the shaft
or part upon which it is provided so that thereby the lubricant may obtain access
to the bearing surfaces uniformly and regularly.
My invention is illustrated in the accompanying drawings in which Figure 1
is a sectional elevation of a lubricating chamber made in accordance with the
present invention, while Figure 2 is a corresponding longitudinal sectional elevation
transverse to that of Figure 1.
In carrying my invention into effect according to the accompanying drawings,
a lubricating chamber b, b, is made into two parts divided at a line coincident with
an axial line of the shaft and such parts are secured one to the other by means
of bolts or pins as indicated.
The lubricating chamber dis applied to the bearing parts such as a and is
secured in position by such means as a screw c and the parts b b are applied upon
the shaft and bolted together. A continuous chain or its equivalent is provided
to hang upon the shaft in such a manner that its lower pendant portion may come
into contact with the lubricant contained in the lower portion of the lubricating
chamber d so that upon each rotation of the shaft a corresponding movement of
the chain is effected with the result that the lubricant which adheres to the chain
from its passage through the lower part of the chamber is applied to the surface
of the shaft and thereby finds access to the bearing parts and surfaces. An
annular space is provided in the parts which lies around the surface of the
shaft, into which packing material is introduced for the purpose of precluding the
oil leaking from the chamber or passing along the shaft.
It is obvious that the lubricating chamber may be applied to one or both sides
of the bearing and any modification in its application or design may be effected
without departing from an essential feature of the invention which consists in a
chain applied to the shaft or upon a rotating part and within a chamber to the
effect of continuously applying lubricant which is conveyed on the movement of
the chain.
It is also obvious that I do not confine myself to any particular form of chain
as I may employ any suitable vehicle of the kind and may also in some cases
provide cup like recesses in the chain links so that the lubricant may be conveyed
to the surface of the shaft in adequate quantity.

page_text: 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. Means for effecting the lubrication of bearing surfaces consisting of a chain
or its equivalent such as e hung upon and rotating with the shaft or rotating part
and provided within a lubricating chamber such as d, such chamber being axially
divided, and provided with a small annular chamber in which packing is inserted
for the purpose of precluding the leakage of oil from the lubricating chamber
substantially as described.
2. Means for effecting lubrication of bearing surfaces substantially as herein-
before described, and as illustrated in the accompanying drawings.
