I, HERMANN BUYTEN, Manufacturer, of Wehrhahn 9. Düsseldorf, 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 roller bearing, of which the accompanying drawing represents an example,
contains rollers arranged in one or mcre compartments, without any journal
bearing at the ends, but supported laterally and held apart by revoluble spindles.
The latter are supported by the axle through the intermediary of rings or drums
adapted to turn on the axle of the roller bearing. If several rings are used,
they are preferably connected together by means of tic bars, to prevent them
from being twisted one against the other. Instead of tie bars, a solid or hollow
sleeve may be used for connecting the rings.
If, as shown by the drawing, the rollers are arranged in two compartments
right and left of a drum or ring g, it is practicable to support the spindles i
in the ring g only, instead of resting also in journal bearings formed in the lateral
rings or discs s, as shown by the drawing. The ends of the rollers are rounded,
in order to reduce friction. As indicated by Fig. 2, the rollers and spindles i
are so arranged, that the centre lines of any two consecutive rollers and the axis
of the intervening spindle i can be connected by a straight line, in order that
the pressure exerted on the spindles may be approximately tangential to the axle a,
and not radial to the same.
If desired, the spindle may be arranged in several compartments, like the
rollers.
Owing to the new construction or arrangement of the roller bearing, the rollers
are accurately guided, as they roll around the axle, without requiring any journal
bearings for the rollers; and their friction is reduced to a minimum, because the
spindles i take part in the motion of the rollers, and because the rounded ends
of the rollers are subject to very little friction.
The rings g and s which are mounted on the axle a and capable of turning
on the same, have sufficient clearance, to avoid unnecessary friction.
The bearing is closed at each end by a screw-cap or cover b.
In the drawings, Fig. 1 is a longitudinal or axial section of a roller bearing
embodying my invention, along line C-D of Fig. 2.
Fig. 2 is a transverse section of the same along the broken line A--B of Fig. 1.
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. A roller bearing comprising in its construction rollers r arranged in one
or more compartments, and revoluble spindles i supported by rings or discs
mounted on the axle and adapted to turn on the same, the said spindles being

the same and to keep them at equal distances apart, substantially as described.
2. A roller bearing constructed and adapted to operate as described and shown
by the drawings.
