Improvements in or relating to the Bearings of Vehicle Wheels.
1, FRANCIS DAY of York Lodge, Kennington Park, in the County of Surrey,
Gentleman do hereby declare the nature of this invention to be as follows:-
This invention relates to the bearings of vehicle wheels.
In constructing the bearings I may employ an axle and box much as usual, but
instead of placing these two in direct contact as at present I place between them
sleeves or equivalent which may at their inner faces bear upon the axle and at
their outer faces fit against the interior of the box of the wheel. I prefer to cone
these on their exterior surfaces so that only the central band upon each sleeve will
engage with the box of the wheel in such a manner that the wheel may turn upon
the sleeves and the sleeves remain fixed upon the axle, or the sleeves may,
turn with the box upon the axle, or partly one and partly the other.
Instead of two separate sleeves a single one may be employed, and the
bearing bands instead of being continous may be divided into segments or
cogs if preferred. The wheel may be retained in position upon the axle in the
usual manner.
The sleeves may be perforated with holes to receive balls so as to form ball-
bearings, the sleeves in this case acting as cages to retain the balls in their proper
places. Or rollers may be inserted upon the underside of the axle in spaces
provided for the purpose and carried upon an axle or axles or merely turning
in the recesses provided for them. Where the rollers are intended to touch
each other I prefer to form the ends conical so that they may merely touch at
the centre.
Dated this 6th day of September 1895.

Improvements in or relating to the Bearings of Vehicle Wheels.
I, FRANCIS DAY, formerly of York Lodge, Kennington Park, but now residing
at 13 Cormont Road, Camberwell, 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 :-
This invention relates to the hearings of vehicle wheels.
The invention will be best understood by reference to the accompanying
drawings in which
Figs. 1, 2, 3 and 4 are longitudinal sections of different forms of the bearing
constructed according to my invention.
Fig. 4 is drawn to a larger scale than Figs. 1, 2 and 3.
Like letters indicate like parts throughout the drawings.
In carrying my invention into practice I employ an axle A and axle box B of
substantially the usual construction, but instead of placing these two in direct
Pin11

page_text: contact, as at present, I place between them sleeves or equivalents C which at
their inner faces, bear upon the axle A and at their outer faces fit against the
interior of the box B which latter may be fitted in the wheel-hub D in the usual
manner. I prefer to cone the sleeves C on their exterior surfaces as shown in
Fig. 1, so that only the central part or band C¹ of each sleeve will engage with
the box B in such a manner that the wheel may turn upon the sleeves and the
sleeves remain fixed upon the axle, or the sleeves may turn with the box upon the
axle, or partly one and partly the other.
Instead of making the sleeves C conical externally as shown in Fig. 1, I may
as shown in Fig. 2, cone them on their interior surfaces so that only the central
part C' of each sleeve will bear on the axle A.
Instead of two separate sleeves C a single sleeve may be employed, and the
bearing bands C' instead of being continuous may, if preferred, be divided into
The axle box B and
segments so as to bear only at parts of their circumference.
the wheel may be retained in position upon the axle A in the usual manner, that
is to say, by a nut E screwed on the end of the axle, and this nut may be covered
in by a cap F screwed on the end of the axle box B also in the usual manner.
As shown in Fig. 3 the sleeves C may be perforated with holes to receive
balls C 2 so as to form ball-bearings, the sleeves in this case acting as cages to
retain the balls in their proper.places.
In the arrangement shown in Fig. 4, I provide recesses A' in the axle A to
receive rollers G which are adapted to rotate on a spindle H inserted endwise into
the axle A as shown in the drawing. These recesses would be in the under or
upper part of the axle according as the wheel supported the weight of the axle,
or vice versa. The rollers G and spindle H are of such dimension and are so
arranged that the former project beyond the periphery of the axle at the lower
part so that they may bear directly upon the inner surface of the axle box B.
The spindle H may be secured against rotation by a screw H¹ inserted into it
from the underside of the axle A and against longitudinal displacement by the
nut E which is adapted to bear against a shoulder H 2 on the spindle. A
portion of the spindle H may complete the screw of the axle A, if inutilated to
accommodate the spindle.
Instead of the rollers being adapted to rotate on a spindle as shown in Fig. 4
they may be solid and be arranged to rotate in contact with the walls of the
recesses A¹; where two or more rollers are employed and no spindle is provided,
the rollers at their ends may rotate in contact with each other, under which
circumstances the ends may be coned or bevelled so that they may merely touch
at the centre and reduce friction.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In a journal bearing reducing the surfaces in frictional contact by the
employment of rollers in the manner described.
2. In a vehicle-wheel bearing the combination with an axle and axle box of one
or more sleeves between them whether capable or not of independent rotation,
substantially as described and illustrated in the accompanying drawings.
3. In a vehicle-wheel bearing the combination with an axle and axle box of one
or more sleeves or cages capable of rotating between them and balls capable of
rotating in the sleeves substantially as described.
4. In a vehicle-wheel bearing the combination with an axle having one or more
recesses and an axle box capable of rotating around it of one or more rollers such
as G capable of rotating within the recesses substantially as described and illustrated
in the accompanying drawings.
5. In a vehicle-wheel bearing the combination with an axle having one or
more recesses and one or more rollers such as G rotating within the said recesses
and an axle box capable of rotating around the axle of a spindle fitted in the

page_text: axle and upon which the rollers rotate substantially as described and illustrated
in the accompanying drawings.
6. The combination and arrangement of parts constituting the complete vehicle-
wheel bearing substantially as described and illustrated in Figures 1 2 3 or 4 of the
accompanying drawings.
