I, HEINRICH LUDWIG GUSTAV MEYER, Manufacturer, of Bolkerstrasse,
Düsseldorf, in the German Empire, do hereby declare the nature of this invention
to be as follows:-
This invention relates to ball-bearings suitable for small and large shafts or axles
and will be described with the aid of the accompanying drawings, of which
•
Fig. 1 is a front view of a ball-bearing embodying my invention,
Fig. 2 is a diagram showing the whole length of the ball race laid out in a
plane.
Fig. 3 is a vertical section corresponding to Fig. 1.
I provide a continuous or endless ball race in the manner indicated by Figs. 2
and 3, so that the balls are not subject to wear always on the same side, but
must turn on their respective axes every time they have travelled the length of
the ball race.
The ball race is formed in a semi-annular lining H held in the body L of the
bearing or plummer block by the cover L¹ and made of any suitable hard metal
usually employed for bearings.
The ball race is composed of two annular grooves R, and R¹ which may be
parallel, and are joined together at the ends by short curves, as shown by Fig. 2.
One of the grooves R¹ is deeper than the other R, as shown by Fig. 3, where the
difference in depth is indicated with a.
As the shaft W revolves, the balls are caused to roll forward on one side R
of the ball race, and when they reach the end, they enter the other race R', and
return in the same to the starting point, but without touching the shaft, owing to
the greater depth of the groove R¹.
The semi-circular connecting grooves B, which guide the balls from the forward
race into the return race, are formed in the cover L' of the bearing.
In the case of large axle bearings two or more independent ball races may be
arranged side by side, and parallel to each other, so that the shaft is supported in
two or more planes or circles. The connecting grooves B may be placed higher up
or lower down in the bearings, according to requirements.

Improvement in Ball-bearings.
EINRICH LUDWIG GUSTAV MEYER, Manufacturer, of Bolkerstrasse,
dorf, in the German Empire, do hereby declare the nature of this invention
n what manner the same is to be performed, to be particularly described and
ertained in and by the following statement:-
This invention, relates to ball-bearings suitable for small and large shafts or axles,
and will be described with the aid of the accompanying drawings, of which
Fig. 1 is a front view of a ball-bearing embodying my invention,

page_text: Fig. 2 is a diagram showing the whole length of the ball-race laid out in a
plane, and
Fig. 3 is a vertical section corresponding to Fig. 1.
I provide a continuous or endless ball race in the manner indicated by Figs. 2
and 3, so that the balls are not subject to wear always on the same side, but must
turn on their respective axes every time they have travelled the length of the ball
race.
The ball race is formed in a semi-annular lining H held in the body L of the
bearing or plummer block by the cover L', and made of any suitable hard metal
usually employed for bearings.
The ball-race is chiefly composed of two semi-annular grooves R and R' which
are preferably parallel and joined together at the ends by short semicircular curves,
as shown by Fig. 2.
One of the grooves, R', is deeper than the other, R, as shown by Fig. 3, where
the difference in depth is designated by A.
As the shaft S revolves, the balls are caused to roll forward on one side R of the
ball-race, as indicated in Fig. 2 by dotted lines, and when they reach the end, they
enter the other race R', and return in the same to the starting point, but without
touching the shaft, owing to the greater depth of the groove R₁.
The semicircular connecting grooves B, which guide the balls from the forward
race into the return race, are formed in the cover L' of the bearing or plummer
block.
In the case of large axle bearings, two or more independent ball races may be
arranged side by side and parallel to each other, so that the shaft is supported in
two or more planes or circles. Each shaft should be supported by at least two
independent bearings, or by two sets of balls. The connecting grooves B may be
placed higher up or lower down in the bearings, according to requirements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A horizontal axle bearing or plummer block having an endless or oval ball
race chiefly formed in a semi-annular lining, said ball race being composed of a
forward race, a return race deeper than the forward race, and a pair of semicircular
recesses formed in the cover so as to connect the forward and backward race,
substantially as described.
2. A horizontal axle bearing or pair of bearings having two endless or oval ball
races, each of which contains a semicircular forward race, a semicircular return
race deeper than the forward race, and a pair of connecting curves, substantially as
described.
