in ball bearing axle boxes
Year: 1898

page_text: I, CHARLES BINGLEY HOBRON, of Boerne, in the County of Kendall and State of
Texas, United States of America, Farmer, 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 improvements in ball bearing axle boxes.
The object of the present invention is to improve the construction of ball bearing
axle boxes and to provide a simple and inexpensive one which will be dustproof and
in which friction will be reduced to a minimum. A further object of the invention
is to remove the wear from the spindle so that the latter will not become worn and
require renewing or altering.
The invention consists in the construction and novel combination and arrangement
of parts, as hereinafter fully described, illustrated in the accompanying drawings and
pointed out in the claims hereto appended.
In the drawings,
Figure 1 is a longitudinal sectional view of a ball bearing axle box constructed in
accordance with this invention and shown applied to a spindle.
Figure 2 is a transverse sectional view.
Figure 3 is a perspective view of the spindle.
Figure 4 is a similar view of the bearing sleeve.
Figure 5 is a detail view of one of the bearing rings.
Figure 6 is a detail view of the nut.
Like numerals of reference designate corresponding parts in all the figures of the
drawings.
designates a bearing sleeve arranged on and interlocked with a spindle 2, and
provided with a series of annular channels or grooves 3, forming ball races and
receiving balls 4, which are interposed between the bearing sleeve 1 and an axle
box 5, forming an outer casing for the balls. The inner end of the bearing sleeve 1
is extended and provided with lugs 6, arranged at intervals and fitting in
corresponding recesses 7, which are formed in a shoulder 8, at the inner end of the
spindle. By this construction, the bearing sleeve is firmly interlocked with the
spindle and is held rigid therewith, so that the spindle is prevented from being worn
and does not require renewing.
The ends 9 and 10 of the axle box are provided with interior annular recesses and
are threaded to receive end bearing rings 11 and 12, which are threaded and
provided with outwardly extending flanges which fit against the edges of the axle
The end rings, which close the ends of the axle box and exclude dust from the
balls, fit on smooth extensions 13 and 14 of the bearing sleeve and are each provided
with an annular series of bearing balls 15, projecting from their outer faces in order
box.

axle nut 16. The bearing balls 15 are arranged in openings 17, extending entirely
through the end rings and having their inner portions threaded and receiving screw
plugs 18, which retain the balls in the openings. The outer ends of the openings are
of less diameter than the diameter of the balls, so that the balls are retained in the
openings while projecting therefrom. The space between the outer end ring 12 and
the inner face of the nut is designed to be covered by a band or washer of any
suitable material, to exclude dust from the bearing faces."
The outer end of the spindle is threaded to receive the nut 16 which retains the
wheel on the axle in the usual manner. The axle box, which is fixed to a wheel,
rotates with the same and the bearing sleeve, which is fixed to the spindle, is
stationary and the wear, which is reduced to a minimum, is borne by the bearing
sleeve, the balls and the axle box.
The invention has the following advantages:-
The ball bearing axle box, which is exceedingly simple and inexpensive in
construction, is dust proof and adapted to reduce friction to a minimum. The
device is also adapted to relieve the spindle of wear, so that it is unnecessary to renew
or alter the same.
Changes in the form, proportion and minor details of construction may be resorted
to without departing from the spirit or sacrificing any of the advantages of
this invention, such as varying the number and arrangement of the balls of the end
bearing rings.
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. In a device of the class described, the combination with a spindle, of a bearing
sleeve arranged thereon and interlocked therewith and provided with a series of
annular grooves or channels forming ball races, an axle box arranged over the
bearing sleeve, balls arranged in the races of the bearing sleeve and extended
from one end of the axle box to the other, and the end rings closing the ends of the 3
axle box, substantially as and for the purposes described.
2. In a device of the class described, the combination of a spindle provided at its
inner end with a shoulder having a series of recesses, a bearing sleeve provided with
a series of annular ball races and having at its inner end a series of projecting lugs
fitting in the recesses of the spindle and interlocking the bearing sleeve with the 3
same, an axle box, and balls arranged in the ball races and interposed between the
bearing sleeve and the axle box, substantially as described.
3. In a device of the class described, the combination of a bearing sleeve designed
to be arranged on a spindle and provided with a series of annular channels forining
ball races, said sleeve having smooth extensions at its ends, an axle box provided 4
at its ends with recesses and having the same threaded, balls interposed between the
bearing sleeve and the axle box, and the threaded end rings arranged on the
smooth extensions of the bearing sleeve and fitting in and closing the ends of
the axle box and engaging the threads of the recesses, substantially as described.
4. In a device of the class described, the combination of an axle box, balls 4
arranged within the same, and an end ring secured to the axle box and provided
at its outer face with a series of balls arranged in openings or sockets and
projecting beyond the face of the ring, substantially as described.
5. In a device of the class described, the combination of an axle box, balls
arranged within the same, an end ring secured to the axle box and provided with 5
openings threaded at their inner portions, balls arranged within the openings and
projecting beyond the outer face of the ring, and threaded plugs closing the inner
ends of the openings, substantially as described.
6. In a device of the class described, the combination of a bearing sleeve, an
axle box, balls interposed between the bearing sleeve and the axle box, and the 5

their faces with projecting balls arranged in sockets or openings, substantially as
and for the purpose described.
