I, JEAN EWALD, of 10, Mauritius Steinweg, Koln, Germany, Gentleman, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a non-dripping oil chamber bearing, illustrated in
Figs. 1, 2, 3, and 4, in which the oil therein is, on the rotation of the shaft, caused
by means of an annular disc fixed thereto or by a brush or pin, to circulate over
the running surfaces of the bearing without the oil being able to pass out of the
bearing.
Below the shaft there is arranged in the centre of the bearing a chamber A
for the reception of the lubricating oil. Upon the shaft there is fixed a two-part
disc B (Fig. 4) which is of such size that it extends almost down to the bottom
of the chamber A. In the cover of the bearing above the oil chamber A there
are provided four troughs C for the reception of oil. Each pair of adjacent
troughs is connected together by the channels I). The four troughs are con-
nected by means of passages E with the lubricating grooves F in the running
surfaces of the bearing. The lubricating grooves open into chambers G pro-
vided in the ends of the bearing, and which communicate through the passages H
with the oil chamber A. The oil is introduced through the opening S (which
can be closed) into the oil chamber A.
On the rotation of the shaft, the oil is, by the action of the disc B fixed on
the shaft, thrown by centrifugal action out of the chamber A, it is then caught

troughs, the oil flows through the passages E into the lubricating grooves F
and passes thence into the two chambers G, whence it returns through the
passages H into the oil chamber A.
Instead of one lubricating apparatus in the centre of the bearing, several of
such apparatus may be arranged side by side and at both ends. For slowly
revolving shafts the discs B are provided with bucket or trough-like blades by
which oil is raised into the channels D). Instead of using discs the oil can be
raised into the channel D by means of brushes fixed to the shaft, said brushes
brushing away the oil on the edges of the channels.

This invention relates to a non-dripping oil chamber bearing illustrated in
Figs. 1, 2, 3 and 4 of the drawings accompanying my Provisional Specification
in which the oil is, on the rotation of the shaft, caused, by means of an annular
disc fixed thereto, or by a brush or pin, to circulate over the running surfaces of
the bearing without the oil being able to pass out of the bearing.
Below the shaft there is arranged in the centre of the bearing a chamber A
for the reception of the lubricating oil. Upon the shaft there is fixed a two-part
disc B (Fig. 4) which is of such size that it extends almost down to the bottom
of the chamber A. In the cover of the bearing above the oil chamber A there
are provided four troughs C for the reception of oil. Each pair of adjacent
troughs is connected together by a channel D. The four troughs are con-
nected by means of passages E with the lubricating grooves F in the running
surfaces of the bearing. The lubricating grooves open into chambers G pro-
vided in the ends of the bearing, and which communicate through the passages H
with the oil chamber A. The oil is introduced through the opening S (which
can be closed) into the oil chamber A.
On the rotation of the shaft, the oil is, by the action of the disc B fixed on
the shaft, thrown by centrifugal action out of the chamber A; it is then caught
by the channels D along which it flows into the four troughs C. From the
troughs, the oil flows through the passages E into the lubricating grooves F
and passes thence into the two chambers G, whence it returns through the
passages H into the oil chamber A.
Instead of one lubricating apparatus in the centre of the bearing, several of
such apparatus may be arranged side by side and at both ends. For slowly
revolving shafts the discs B are provided with bucket or trough-like .ades by
which oil is raised into the channels 1). Instead of using discs the oil can be
raised into the channel D by means of brushes fixed to the shaft, said brushes
brushing away the oil on the edges of the channels.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. An oil chamber bearing provided with one or more oil chambers in the
lower part of the body thereof, and with troughs below the cover of the bearing
and at the upper part of the shaft, the rotatory shaft having fixed thereon one or more
discs, pins or brushes that enter the lower oil chamber or chambers during the rota-
tion of the shaft, and the arrangement being such that the oil is conveyed from the
lower chamber or chambers as the shaft rotates and thrown into the upper
troughs from which it flows through passages into the lubricating grooves in the
running surfaces of the bearing substantially as described.
2. Bearings provided with lubricating means substantially as herein before
described with reference to and shown in the drawings annexed.
