page_text: I, GUSTAV BUCHHOLZ, Engineer, of
German Empire, do hereby declare the
Berlin in the Kingdom of Prussia and
nature of the said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
.
In the annexed Drawings which make a part of this Specification
Figure 1 shows a front elevation of a bearing according to this Invention.
Figure 2 shows a longitudinal section of same.
Figure 3 shows a front elevation of a modified bearing.
Figure 4 shows a side view of Figure 3, the bearing shell partly broken away.
Figure 5 shows the connection of two rollers.
The bearings used hitherto for railway cars and carriages, shafts and the like,
have the disadvantage of two large a friction surface. This entails a heavy loss
of power and a great quantity of lubricant is wanted to prevent the heating of
the bearings, axles and shafts. Nevertheless such heating happens very often and
causes rapid destruction of the parts above mentioned. Even though a great
number of kinds of devices are now used as lubricating boxes, they possess this
adhering deficiency. Besides this a very extensive attention is wanted to examine
and control the temperature of axles.
To remove this inconvenience I emply a system of cylinders and balls round the
axle as shown in the Drawings. The axle A is surrounded with a set of short
rollers B, these rollers being encircled by a bearing shell C. In order to prevent
the rollers being dislodged and for the purpose of facilitating the operation of this
mechanism, balls D are placed between the bearing shell C and the rollers B. The
effect obtained by this mechanism consists in offering to the shafts, or axles only
a very small friction surface which will not be liable to heat and in saving working
power of nearly 75 per cent. The balls D run within grooves a cut in the rollers B
and the bearing shell C. The groove within the bearing shell is provided with a
metal ring E which can be easily changed if worn. The ring E has a form which
allows a small space at E¹ for expansion. Another device but of the same system
is shown by Figures 3. 4 and 5. The axle A is turned out to a smaller diameter
and the rollers B¹ partly move within it. Instead of balls a set of smaller rollers Fi
s applied, the rollers B¹ and rollers F¹ being held in position together by grooves c²

between this ring and the bearing shell and work in perforations in the ring r.
The exchange of damaged parts is easily effected, the bearing shell consisting of
two parts held together by screws. If one half of the bearing has become defective
it is only necessary to change its position.
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
First. A bearing for axles and shafts consisting of two semi cylindrical shells C
with a communicating groove and a ring E in combination with short rollers B and
balls D rotating in the grooves between the ring E and the rollers B. --
Second. A bearing for axles and shafts consisting of two semi cylindrical shells-0
with a communicating groove E¹ and a ring d moveable on balls K in combination
with the rollers B¹ and rollers F¹ having collars c moving in grooves o¹.
