York, Machine Maker, for the Invention of "IMPROVEMENTS IN BEARINGS FOR
ROTARY SHAFTS AND AXLES." A communication from abroad by Julius Lange
and Alwin Eisenbraun, of Lodz, in the Kingdom of Poland.
Scaled the 15th September 1877, and dated the 27th March 1877
PROVISIONAL SPECIFICATION left by the said William Speakman Yates at
the Office of the Commissioners of Patents on the 27th March 1877.

"IMPROVEMENTS IN BEARINGS FOR ROTARY SHAFTS AND AXLES." A communication
from abroad by Julius Lange and Alwin Eisenbraun, of Lodz, in the Kingdom of
Poland.
The object of this Invention is, by an improved arrangement and combination of
"E runners or antifriction pulleys and supporting rings, to construct bearings for
shafting axles of railway carriages, tram cars, and other rotary axles, in such manner
as to reduce friction and the use of oil or lubricants to a minimum.
#t
The axis or shaft is supported within and by four antifriction pulleys or
'runners;" the spindles or gudgeons of the latter support an internal ring which
is free to rotate. The antifriction pulleys or "runners are prevented from coming
in contact with each other, and so causing friction, by four smaller runners or rollers
placed within the four spaces between the antifriction rollers or runners which
support the shaft or axle. The smaller rollers also serve to support upon their
outer periphery an external ring, which is likewise free to rotate; the internal
and external rings are connected by means of a disc at each side thereof, and the
bracket, hanger, standard, or pedestal at its extremity is circular, and recessed or
forked to admit the introduction and free working of the improved bearing above
described.
Although in the foregoing description I have described the use of four anti-
friction rollers, spindles, and smaller rollers, it will be understood that other number
of such appliances may be used in like manner in the construction of my improved
hearings

The object of this Invention is, by an improved arrangement and combination of
"
runners or antifriction pulleys and supporting rings, to construct bearings for
shafting axles of railway carriages, tram cars, and other rotary axles, in such manner
as to reduce friction and the use of oil or lubricants to a minimum.
The axis or shaft is supported within and by four antifriction pulleys or
'runners;" the spindles or gudgeons of the latter support an internal ring which
is free to rotate. The antifriction pulleys or
" runners are prevented from coming
in contact with each other (and so causing friction) by four smaller runners or rollers
placed within the four spaces between the antifriction rollers or runners which
support the shaft or axle. The smaller rollers also serve to support upon their
outer periphery an external ring, which is likewise free to rotate; the internal and
external rings are connected by means of a disc at each side thereof, and the
bracket, hanger, standard, or pedestal at its extremity is circular, and recessed or
forked to admit the introduction and free working of the improved bearing above
described.
Although in the foregoing description we have described the use of four anti-
friction rollers, spindles, and smaller rollers, it will be understood that other number
of such appliances may be used in like manner in the construction of our improved
bearings.
Such being the nature and object of the said Invention, in order that the same
may be fully understood a Sheet of Drawings is annexed hercto, shewing the con-
struction of an improved bearing according to this Invention, and the following is a
full description of the Drawings.
Fig. 1 is a front elevation of a bearing constructed according to this Invention;
Fig. 2 is a plan partly in section of Fig. 1, on the line
ს.
Fig. 3, section of shaft or axle and its supporting rollers.
Fig. 4 is an elevation of the supporting ring; Fig. 5 is section of Fig. 4.
Fig. 6 and Fig. 7 are details shewing rollers and runners detached.
Fig. 8, wall box and ball for preventing lateral or endwise movement of the shaft
or axles.
A is the shaft or axle supported by the rollers B, B, B, B, and to which it com-
municates rotation. The rollers B, B, B, B, run on the antifriction runners C, C, C, C,
the latter rolling upon the inner flange C¹ of the rings F, F, and also rotate with the
rollers and axle.
The rollers B, B, B, B, are spaced or retained at distances apart by the four
intervening rollers H, H, H, H, the ends of which also roll upon the outer flange E
of the rings F, F. The rollers B, B, B, B, and H, H, H, H, are recessed or cut to
less diameter near each end, as shewn at m, in order, by the projecting rims n, to
prevent lateral or endwise motion of the rollers B, B, B, B, and H, I, H, H, and
to retain the rings F, F, in position; P is the neck and R the cap which are recessed,
as shown. At L is shewn a ball partly enclosed within a box M, which, in case of
free end shafts having tendency to lateral or endwise motion, will be fixed in the
wall or carried by brackets, so that the ball L is free to roll along with the motion
of the axle or shaft A. When from use one or more of the rollers become worn it
will be necessary only to replace one larger roller, as accuracy of relativo diameter
is not necessary to efficiency; or when the rollers B, B, B, B, are worn larger,
antifriction runners C, C, C, C, may be applied to the gudgeons; in lieu of replacing

page_text: any of the rollers the rings F, E, and C1, may be made in parts or sections, as shown
by Drawings at Fig. 9, to admit of application to shaft, without having to pass the
rings from the ends thereof.
It will be understood that other number or diameter of rollers B or rollers H
may be employed.
No claim is made to the supporting and running of an axle or shaft upon rollers,
per se; what I claim is the combination of the rollers B, B, B, B, and H, H, H, H,
and ring F, F, E¹, and C¹, substantially as and for the purpose herein set forth.
In witness whereof, I, the said William Speakman Yates, have hereunto set
my hand and seal, this Twenty-second day of September, in the year of our
Lord One thousand eight hundred and seventy-seven.
