Improvements in Axles and Bearings, such Improvements being also
Applicable to Shafts and Spindles..
I, JOHN STONE, of 168, High Street, Stoke Newington, London, N., Perambulator
Manufacturer, do hereby declare the nature of my said invention to be as
follows:
-:
My invention relates more particularly to that construction and arrangement of
axles and bearings described in the Specifications of my Letters Patent No. 17,764
of 1889, and consists in an improved method of locking the nut to the axle box or
hub and in the method of fitting the nut to the axle.
According to my invention, I form the edge of the nut with a number of notches
or cuts and provide the axle box or hub with a pivoted catch or pawl arranged to
engage with the notches of the nut and prevent independent rotation of the latter.
The catch or pawl is retained in its locked or unlocked position by a spring acting
on flats formed on the back end of the catch or pawl.
According to my said Patent No 17764 of 1889 it was necessary to make the
axle in two parts in order that the nuts might be placed in position behind the
double coned collar or flange after which the axle was welded or otherwise joined
together. I now form the collar or flange with a single coned surface arranged to
fit the corresponding conical surface in the axle box or hub and cut an annular
groove at the base of the cone. The nut is made of a size that will pass over the
cone, the interior of the nut being screw threaded as before but formed with a
flange instead of a conical surface. A slotted washer or collar is placed in the
groove, and when the nut is screwed on to the axle box or hub, the washer is
enclosed by and in the nut, the washer being thus retained in the groove and
acting as the back cone of the double coned collar or flange, described in my said
former patent, to retain the axle box or hub in position on the axle.

Improvements in Axles and Bearings, such Improvements being also
Applicable to Shafts and Spindles.
I, JOHN STONE, of 168, High Street, Stoke Newington, London, N., Perambulator
Manufacturer, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention relates more particularly to that construction and arrangement of

page_text: axles and bearings described in the Specification of my Letters Patent No. 17,764
of 1889, and consists in an improved method of locking the nut to the axle box or
hub and in the method of fitting the nut to the axle.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a longitudinal section illustrating the application of my invention to
the axle and hub of a baby carriage, and from which its application to other shafts,
spindles and bearings will be readily understood.
Fig. 2 is a cross section of Fig. 1 on the line x, x.
According to my invention, I form the edge or flange a of the nut b with a
number of notches or slots c, and provide the hub d with a lever or pawl e, pivoted
at el, in such a manner that the lever or pawl e is capable of engaging with the
notches or slots c and thus locks the nut 6 on the hub and prevents independent
1otation. The lever or pawl e is retained in either its locked or unlocked position
by a spring which acts on the Hats formed on the back end of the pawl, as
shown in Fig 1.
In order to obviate the necessity of making the axle in two parts to enable the
adjusting nuts to be placed in position (as was necessary with with the arrangement
described in my said former Letters l'atent), I form the axle with a single cone g,
and cut an annular groove h at the base, as shown; a slotted washer or collar i fits
and works in the groove, the nut b being formed with a flange 6 of a sufficient
internal diameter to pass over the cone g and yet be able to engage the washer or
collar i and render the bearing adjustable.
In using my invention, the nut 6 is first passed over the cone g on to the axle ;
the slotted washer or collar i is then placed in position in the groove h, and the
hub d is put on the axle, the lever e being placed vertically. The nut is then
screwed on to the hub (enclosing the collar i) until the bearing is sufficiently
tight, when the lever e is pressed downward into one of the notches c of the
flange a on the nut b.
In some cases the back face of the collar i is formed as a cone fitting a similar
formation of the nut flange b¹, or the collar may be formed conically on either or
both face or faces, and made in two parts arranged to form a complete collar when
in position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved construction and arrangement of axle and bearings, suitable
also for shafts and spindles, substantially as set forth.
2. In axles, shafts, spindles and their bearings or hubs, the combination of a
nut for adjusting the bearing formed with a notched flange, a lever or pawl
engaging the notches of the flange, a spring for controlling the lever, and a detach-
able collar enclosed by the nut, severally arranged and operating, substantially as
set forth.
3. The combination of a nut capable of being locked, a flat or coned collar
formed with a slot or in two parts, to enable it to be placed in a suitable groove
in the axle, and a flange on said nut, substantially as set forth.
