PROVISIONAL SPECIFICATION.
Improvements in Axles or Shafts and their Bearings.
I EDWARD WILLIAM GOUGH PомROI of 137 Great Dover Street in the County
of Surrey Gentleman do hereby declare the nature of this invention to be as
follows:
The object of this invention is to reduce the friction between axles and wheels and
also between shafts and their bearings.
According to this invention I form either in the axle or bearing three or more
recesses whereof one is at the bottom of the said axle or bearing and two at least
between the bottom and the horizontal centre line and in the recesses I insert loosely
hardened steel rollers of the same length as the bearing. The recesses are nearly
cylindrical so that the rollers when inserted therein project slightly beyond the
cylindrical surface of the axle or bearing and the recess being more than semicircular
the rollers will not fall out. The said rollers are inserted from one end of the axle or
bearing and are kept in position endwise by means of a suitable collar at the end from
which the rollers are inserted the other end of the axle or bearing being provided
with a shoulder.

COMPLETE SPECIFICATION.
Improvements in Axles or Shafts and their Bearings.
I EDWARD WILLIAM GOUGH POMROI of 137 Great Dover Street in the County of
Surrey Gentleman 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 object of this invention is to reduce the friction between axles and wheels and
also between shafts and their bearings.
According to this invention I form either in the axle or bearing three or more
recesses whereof one is at the bottom of the said axle or bearing and two at least
between the bottom and the horizontal centre line and in the recesses I insert loosely
hardened steel rollers of the same length as the bearing.
The recesses are nearly cylindrical so that the rollers when inserted therein
project slightly beyond the cylindrical surface of the axle or bearing and the recesses
being more than semicircular the rollers will not fall out. The said rollers are inserted
from one end of the axle or bearing and are kept in position endwise by means of a
suitable collar at the end from which the rollers are inserted the other end of the axle
or bearing being provided with a shoulder.

Figure 1. represents side elevation of carriage axle constructed according to this
invention.
Figure 2. cross section of same.
Figure 3. end view of same.
Figure 4. end view of same with collar and rollers removed.
Figure 5. is end view of a bearing or step for a rotating shaft constructed according

page_text: a. is the axle b. the rollers c. the recesses in the axle to contain the rollers, d. the
collar to keep the rollers in position e. e. pins to prevent collar from rotating f. nut to
secure collar to axle, g. screw.
In Figures 5, 6 and 7. h. is step i. rollers k. collar to keep rollers i. in place
1. screws to secure collar k. to step.
The rollers b. and i. may be made in short lengths as shewn instead of in one piece,
the number of rollers in each recess being sufficient to extend the whole length of the
axle or bearing.
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
I. In axles and bearings the use of hardened steel rollers rotating in longitudinal
grooves in the axle or bearing substantially as described for the purpose stated.
II. The improvements in axles or shafts and bearings substantially as described
and shewn.
