PROVISIONAL SPECIFICATION.
Improvements in Axles and Bearings, such Improvements being
also applicable to Shafts, Spindles, and analogous Machinery.
I JOHN STONE, of 168 High Street, Stoke Newington, in the County of
Middlesex, Perambulator Manufacturer, do hereby declare the nature of my said
invention to be as follows:—
The object of my invention is to effect improvements in the construction of the arms
of axles and the boxes or bearings for the same; such improvements being also
applicable to shafts and spindles and analogous machinery.
In carrying out my invention, I form the outer end of the axle arm conical, and at
the shoulder of the arm, I form or fit a double conical flange or collar. The axle box
is closed entirely at its outer end, a small central countersunk socket being inade
inside the outer end, to receive the conical end of the axle arm.
The axle box is also provided with a broad flange near its inner end, next to the
shoulder, such flange having a circle of small holes, near its periphery, to receive the
end of a spring bolt or a set screw.
The inner end of the axle box is coned to correspond with the conical collar on the
axle arm. Externally, the inner end of the box is screw threaded, to receive a nut
with a corresponding internal screw thread. This nut is coned to fit the conical
collar on the arm. A spring bolt or a set screw is fitted to the nut for setting the
sane when adjusted.
When the axle arm has been inserted in the box, the nut is screwed on to the box,
thus enclosing the double coned flange, and securing the box in position on the arm,
and, when properly adjusted, the spring bolt (or the set screw) is cansed to enter one
of the holes in the flange of the box, whereby the nut is set, and is rendered
incapable of working loose.
My invention is applicable to wheels and axles and all kinds of revolving spindles
and other machinery.
COMPLETE SPECIFICATION.
Improvements in Axles and Bearings, such Improvements being
also applicable to Shafts, Spindles, and analogous Machinery.
1, JOHN STONE, of 168 High Street, Stoke Newington, in the County of
Middlesex, 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 :-
The object of my invention is to effect improvements in the construction of the
arms of axles, and the boxes or bearings for the same; such improvements being also
applicable to shafts and spindles and analogous machinery.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a sectional elevation showing an axle arm and box fitted in accordance
with my invention.
Fig. 2 is a back view of the same.
a is the axle, b the axle arm, b' is the conical end, and 6 is the double coned
shoulder or collar. c is the axle box, which may be made solid at its outer end as

page_text: shown, or a screw plug may be inserted.
A small central countersunk socket c' is
made in the outer end as shown, to receive the conical end of the axle arm.
Tho
axle box is also provided with a broad flange d near its inner end, next to the
shoulder, this flange has a number of holes ee near its periphery, to receive the end
of the spring bolt f, or a set screw. The inner end of the axle box is coned to
correspond with the conical collar 6. This portion of the axle box is screw threaded
externally, to receive the nut g. This nut is also screw threaded and coned to fit the
collar 6. In the drawings a spring bolt is shown, for setting and locking the nut
the holes ee being provided in the flange d for receiving the end of the bolt f
A set screw may be fitted in a similar manner.
When the axle arm has been inserted in the box, the nut is screwed on, thus
enclosing the double coned flange, and securing the box in position on the arm,
and, when proporly adjustod, the spring bolt (or the set screw) is caused to enter one
of the holes in the flange of the box, whereby the nut is set, and is rendered incapable
of working loose.
My invention is not only applicable to wheels and axles, but also to all kinds of
revolving spindles and other inachinery.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what mannor the same is to be performed, I declare that what I
claim is
In the construction of axles and bearings, the combination of an axle arm b, having
a conical end, and double coned collar ³, with an axle box c closed at its outer
end and coned at its inner end, and fitted with an adjustable coned nut, having a
spring bolt for a set screw for adjusting the nut 9, substantially as hereinbefore
described and illustrated by the drawings.
