PROVISIONAL SPECIFICATION.
Improvements in or relating to Axle Bearings.
I, FRANCIS ROBERT RICHARD DAY, of 304 East Street, Walworth, in the County
of Surrey, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to axle bearings in which the axle rotates, and the load bears
upon the upper surface of the axle.
In carrying out the invention the axle is carried in slotted bearings or the
equivalent, in which are placed the necessary number of rollers, each provided with
its own rotating axle, or with a fixed axle, upon which itself rotates. In the case
for example of a vehicle wheel I may provide the slotted bearings in the form of
horn-plates, one outside the road wheel and the other inside, and in each of the slotted
horn-plates 1 may place one roller, the periphery of which would engage with the
axle. If desired one or more balls or rollers may be employed behind the rollers
above described.
Or instead of having a single roller I may have two or more over-lapping so as to
provide a necessary bearing. I may also employ rollers to take the horizontal thrust
of the shaft, either in a fore and aft action or transversely, and instead of having
single rollers I may in all cases employ a larger number.
If desired, the springs, should such be used, may be applied to the supporting
rollers or their axles.
Dated this 18th day of November 1895.

1, FRANCIS ROBERT RICHARD DAY, of 304 East Street, Walworth, 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 axle bearings in which the axle rotates, and the load bears
upon the upper surface of the axle.
The invention will be best understood by reference to the accompanying drawings,
in which
Figure 1 is a section on the line 1-1 of Figure 2, and
Figure 2 is a section on the line 2-2 of Figure 1 showing one form of the axle
bearing constructed according to this invention.
Figure 3 is a section on the line 3-3 of Figure 4, and
Figure 4 is a section on the line 4-4 of Figure 3, these two views showing a
modification of the bearing illustrated in Figures 1 and 2 ;
Figures 5 and 6 are-transverse-and- longitudinal sections respectively of another
modification of axle bearing according to this invention, and
Figures 7 and 8 are views similar respectively to Figures 5 and 6 showing a
further alternative construction.
Like letters indicate like parts throughout the drawings.

page_text: In carrying out the invention the axle A is carried in slotted bearings, axle boxes
or equivalent B, in which are placed the necessary rollers C, each provided with an
axle C¹ which either rotates with the roller or is fixed so that the roller rotates upon
it. In the case for example of a vehicle wheel such as the wheel A' shown in
Figure 1 the axle box B may be mounted so that it inoves vertically in horn plates or
guides D as shown, the axle B in this example having one roller Ċ the periphery of
which engages with the axle. If desired one or more rollers E may be employed
behind the roller C as in the modification illustrated in Figures 3 and 4, in which a
series of rollers E pivotted in the axle box support at its upper side the circumference
of the roller C which bears at its lower side upon the axle A. In the modification
illustrated in Figures 5 and 6 three rollers are employed; one of them C² interposes
between the other two, C, as shown, so that the rollers C bear upon the periphery of
the axle at one side of the vertical axial plane thereof, and the other roller bears
upon it at the other side of the plane; in this arrangement the two rollers Care
mounted on the same axle C¹, either both fast or both loose upon it or one may be
loose and the other fast.
In the modification shown in Figures 7 and 8 the axle A is surrounded on three
sides by rollers C parallel with it and each other.
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 an axle-bearing the combination with horn plates or guides D of an axle box
movable therein and containing roller bearings substantially as described and illustrated
in Figures 1 and 2 of the accompanying drawings.
2. In an axle bearing the combination with horn plates or guides D of an axle-box
movable therein containing a roller C and auxiliary rollers E substantially as described
and illustrated in Figures 3 and 4 of the accompanying drawings.
3. The combination and arrangement of parts constituting a complete axle-box
substantially as described and illustrated in Figures 1 and 2 or Figures 3 and 4 or
Figures 5 and 6 or Figures 7 and 8 of the accompanying drawings.
Dated this 17th day of August 1896.
