We, the company MÜHLENBAUANSTALT und MASCHINENFABRIK VOorm. GEBRÜDER
SECK, at Dresden, Germany, and I, HANS KRUSEMARK, Engineer, at Dresden,
Germany, do hereby declare the nature of this invention to be as follows;―
The invention relates to a lubricating ring for eccentric bearings, being
specially adapted in such cases, where, on account of the high number of revolu-
tions of the shaft, or from other reasons, the usual lubricating hole upon the
sliding rod head, or upon the eccentric body, respectively, offers no safety for a
sufficient supply of lubricating material to the eccentric pivot.
The arrangement is shown in the accompanying drawing.
Fig. 1 represents a longitudinal section.
Fig. 2 shows a cross section through the bearing.
Figs. 3 and 4 are modifications of the arrangement of the eccentric pivot, on a
reduced scale.
a is the eccentric pivot of a revolving shaft b. In the middle (Fig. 1) or near
the middle (Fig. 3) or at the ends of this pivot (Fig. 4) is a shoulder e, arranged
concentrically to the shaft b, but not to the pivot a
Upon this shoulder rests the usual ring, which, in this case, is considerably
larger than the pivot. This ring is so arranged that its inner edge is supported
by the highest point of the shoulder and that it projects on both sides of the
entire bearing body, dipping with its lower end into an oil box, which serves,
at the same time, as protecting case e of the eccentric bearing, as shown in
Figs. 1 and 2.
In its middle, the bearing socket f upon the eccentric head has the form of
a ring-shaped chamber f¹, in which the shoulder c, arranged eccentrically to
the pivot a can freely move. The ring-shaped chamber is provided with the
openings f, through which the divided lubricating ring is put when mounting
the bearing.
In accordince with the above-described arrangement of the bearing socket f,
the sliding rod head is provided with openings, so as to provide a passage for
the lubricating ring g (Fig. 2).
At the upper end of the bearing socket f, and projecting from the highest
point of the shoulder c, are two longitudinal grooves g. These two grooves may
extend to another groove, having the form of a semi circle, arranged upon the
inner surface of the bearing socket, as shown by the dotted lines in Fig. 1.
If the shaft is made to rotate, the shoulder c in the chamber f¹ will likewise
rotate around the shaft, in opposite direction to the pivot a. The lubricating
ring. resting upon it, will rotate in the usual way, so as to partly carry the oil,
sticking to it by dipping into the oil box, up to the highest point of the shoulder.
The outer edges h in the chamber f¹ will then strip off the oil and carry it

tion towards two longitudinal sides of the bearing.

Improvements in Eccentric Bearings with Ring Lubrication.
We, the company MÜHLENBAUANSTALT und MASCHINENFABRIK vormals GEBRÜDER
SECK, at Dresden, Germany, and I, HANS KRUSEMARK, Engineer, at Dresden,
Germany, 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:-
:—
The invention relates to a lubricating ring for excentric bearings, being
specially adapted in such cases, where, on account of the high number of revolu-
tions of the shaft, or from other reasons, the usual lubricating hole upon the
sliding rod head, or upon the eccentric body, respectively, offers no safety for a
sufficient supply of lubricating material to the eccentric pivot.
The arrangement is shown in the drawing, filed with our Provisional Speci-
fication.
Fig. 1 represents a longitudinal section.
Fig. 2 shows a cross section through the bearing.
Fig. 3 and 4 are modifications of the arrangement of the eccentric pivot, on a
reduced scale.
a is the eccentric pivot of a revolving shaft b. In the middle (Fig. 1) or near
the middle (Fig. 3) or at the ends of this pivot (Fig. 4) is a shoulder e, arranged
concentrically to the shaft b, but not to the pivot a.
Upon this shoulder rests the usual ring, which in this case, is considerably
larger than the pivot. This ring is so arranged that its inner edge is supported
by the highest point of the shoulder and that projects on both sides of the
entire bearing body, dipping with its lower end into an oil box, which serves,
at the same time, as protecting case c of the eccentric bearing, as shown in
Figs. 1 and 2.
In its middle, the bearing socket f upon the eccentric head has the form of
a ring-shaped chamber f¹, in which the shoulder e arranged eccentrically to
the pivot a, can freely move. The ring-shaped chamber is provided with the
openings through which the divided lubricating ring is put when mounting
the bearing.
In accordance with the above described arrangement of the bearing socket f,
the sliding rod head is provided with openings as to provide the passage for
the lubricating ring (Fig. 2).
At the upper end of the bearing socket f, and projecting from the highest
point of the shoulder c, are two longitudinal grooves g. These two grooves may
extend to another groove, having the form of a semi-circle, arranged upon the
inner surface of the bearing socket, as shown by the dotted lines in Fig. 1.
If the shaft is made to rotate, the shoulder in the chamber f¹ will likewise
rotate around the shaft. The lubricating ring, resting upon it, will rotate in the
usual way, so as to partly carry the oil, sticking to it by dipping into the oil-
box, up to the highest point of the shoulder.
The outer edges h in the chamber f¹ will then strip off the oil and carry it

page_text: into the grooves 9 connected with the pivot a, thus effecting a uniform distribu-
tion towards two longitudinal sides of the bearing.
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. Excentric bearing with ring-lubrication, characterised by one от more
shoulders e arranged eccentrically to the pivot a and concentrically to the shaft b,
upon which shoulders rests the lubrication ring y, for the purpose as described.
2. In an eccentric bearing with ring-lubrication in combination with the
shoulder e, arranged at the middle of the pivot a, the longitudinal grooves g¹
in the bearing socket f, the chamber f¹, and the outer edges h, for the purpose
as described.
