PROVISIONAL SPECIFICATION.
Improvements relating to the Lubrication of Bearings.
We DAVID HAHN and KARL TREIBER both of Stockerau, near Vienna
Austria Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the lubrication of bearings, and has for its object to
cause the circulation of the lubricant introduced into a bearing and to prevent it
from leaving the latter. For this purpose the top brass of the bearing is
provided with a lubricating hole and an annular inlet groove extending from
this hole.
The bottom brass of the bearing has on one of its edges a longitudinal recess
which is either straight or more or less inclined towards both ends. From the
ends of the said recess branch off return grooves which extend across the bottom
brass and meet on the other side at the point where the above mentioned inlet
groove terminates at the bottom brass. In this manner the communication of the
two ends of the inlet groove in the top brass with the longitudinal recess and the
return grooves is established.
To prevent the lubricant flowing from the bearing at the two ends of the brasses
are formed grooves for the reception of either spring holding rings of metal or
other suitable elastic material such as leather, india-rubber, stuffing-box packing etc.
The brasses must be constructed in such a manner that a tight joint is formed between
them with or without the intervention of packing material.
The mode of lubrication is as follows that is to say the lubricant which enters
the aforesaid inlet groove through the lubricating hole is carried away by adhesion,
by the rotary shaft & is deposited in the longitudinal recess, flows to the two ends
of the latter passes into the return grooves, and being carried away by the rotary
shaft, again enters the inlet groove.
In the case of large bearings two or more of the described arrangements may be
employed side by side.

Improvements relating to the Lubrication of Bearings.
We, DAVID HAHN, and CARL TREIBER, both of Stockerau near Vienna,
Austria, Engineers 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 :-

page_text: The bottom brass of the bearing has on one of its edges a longitudinal recess b
which is either straight or more or less inclined to both ends. From the ends of
the said recess branch off return grooves c and d which extend across the bottom
brass and meet on the other side at the point where the inlet groove a terminates
at the bottom brass. In this manner the communication of the two ends of the
inlet groove a in the top brass with the longitudinal recess and the return
grooves c d is established.
To prevent the lubricant from flowing from the bearing at the two. ends of the
brasses there are formed grooves e for the reception of either spring holding rings
of metal or other suitable elastic material such as leather, india-rubber, stuffing-
box packings &c. The brasses must be constructed in such a manner that a
tight joint is formed between them with or without the intervention of packing
material.
The mode of lubrication is as follows:-The lubricant which enters the aforesaid
inlet groove a through the lubricating hole is carried away by adhesion by the
rotary shaft and is deposited in the longitudinal recess in which it flows to the
two ends thereof, passes into the return grooves c and d, and being carried away by
the rotary shaft, again enters the inlet groove a.
In the case of large bearings two or more of the described arrangements may be
employed side by side.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. An improved means of lubricating bearings consisting in providing the top
brass with a lubricating hole and a semicircular inlet groove a extending from this
hole, while the bottom brass has on one of its edges a longitudinal recess b which is
either straight or more or less inclined and from the ends of which branch off return
grooves c and d which extend across the bottom brass and meet on the other side
at the point where the above mentioned inlet groove a terminates at the bottom
brass, substantially as set forth.
2. In combination with the lubricating device, described in Claim 1 the application
of springy or elastic rings provided in grooves at both ends of the brasses and
embracing the shaft, substantially as described.
