PROVISIONAL SPECIFICATION.
A New and Improved Vehicle Wheel Bearing.
I, JOHN PETTINGER of 132, Santa Barbara Street, Santa Barbara, in the
County of Santa Barbara and State of California, United States of America,
Gentleman, do hereby declare the nature of this invention to be as follows:-
According to my invention the hub of the vehicle wheel is provided with a hub
box made cylindrical at its inner end and solid near the forward end with a spindle
projecting from the solid end rearwardly through the cylindrical part. This spindle
extends into the tubular end of the axle and is reduced at the end to engage in a
bearing secured in the tubular part of the said axle. The outer end of the spindle
is formed with an enlargement which is received in a counter enlargement formed
at the adjacent end of the axle.
The spindle is about eighteen inches long so as to afford a good connection
between the spindle and the axle. A collar or nut screws on the inner end of the
hub box which abuts at its inner end on a shoulder formed by an enlargement
shrunk or otherwise secured to the end of the axle. The inner end of the hub box is
preferably provided with a flange engaging with a shoulder formed in the inner
recessed end of the hub. If desired an axle stock may be attached to the axle by
a clip in the usual manner. The forward solid end of the hub box is provided with
the usual threaded reduced portion on which screws a nut abutting on a collar
resting on a shoulder in the outer recessed end of the hub. A dust cap is secured
on the outer end of the hub to prevent dust from passing to the hub box and a
similar dust cap is secured to the axle to extend with its flange over the collar
screwing on the inner end of the hub box.

A New and Improved Vehicle Wheel Bearing.
I, JOHN PETTINGER of 132, Santa Barbara Street, Santa Barbara, in the
County of Santa Barbara, and State of California, United States of America,
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 :-
The invention consists principally of a hub box having an integral spindle
adapted to engage a tubular axle.
The invention also consists of certain parts and details and combinations of the
same as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar characters of reference indicate corresponding
parts in both the figures.
Figure 1 is a sectional side elevation of the improvement;
Figure 2 is a sectional view of a modified form of dust cap.

page_text: The hub A of the vehicle wheel is provided with a hub box B, made cylindrical,
and solid at the outer end, and has a spindle B' projecting from the solid end
rearwardly through the cylindrical part, as plainly illustrated in the drawings.
This spindle B' extends into the tubular part C¹ of an axle C, and the end of the
said spindle is reduced as at C, to turn in a hearing D secured in the tubular part
of the said axle C. The outer end of the spindle is formed with an enlargement
which is received in a counter enlargement y formed at the adjacent end of the
axle C.
The spindle B' is preferably about eighteen inches long, so as to afford a good
connection between the spindle and the axle. A collar or nut E screws into the
end of the hub box B, and engages with shoulder formed by an enlargement C³
shrunk or otherwise secured upon the end of the hollow axle C. The hub box B,
is preferably provided with a flange B3 engaging with a shoulder A' of the hub A.
If desired, an axle stock F may be attached to the axle C by a clip G in the
usual manner.
The solid end of the hub box B is provided with the usual threaded reduced
portion B', to receive a nut G¹ and washer Gabutting against a shoulder A³ at the
outer recessed end of the hub A. A cap H is secured on the end of the hub A to
exclude dust from the hub box, and a similar dust cap H¹ may be secured to the
axle C so as to enclose the collar E as shown in Figure 2.
A considerable quantity of lubricant can be received in the space between the
spindle B¹ and the tubular part C' of the axle, so that the wheel can be run for a
long time without requiring a re-application of the lubricant.
By means of the arrangement described, the friction of the bearing parts is
reduced to a minimum and the wheel hub A by reason of the long spindle B¹ will
always maintain a proper relation to the axle C, so that the wheel will run
perfectly at all times, and consequently, wabbling of the wheel is prevented. It
will further be seen that by the arrangement described, the axles can be very
easily set and are less liable to get out of the true set.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
1. A vehicle bearing, comprising a hub having a hub box therein, the same
being hollow, a centrally located spindle projecting from the outer end of the hub
box inwardly and beyond the hub and having at its inner extremity a reduced
portiou and having an enlargement at its outer extremity, a hollow axle fitting in
the hub box and receiving the spindle and having at its inner portion a bearing
receiving the inner end of the spindle, the axle also having a counter enlargement
at its outer extremity receiving the enlargement at the outer portion of the spindle,
and an exteriorly threaded collar embracing the hollow axle and screwing into the
inner end of the hub box, substantially as described.
2. A vehicle bearing, comprising a hub, a hub box therein, the same having an
axially coincident recess, a spindle centrally within said recess and projecting
inwardly and beyond the hub and having its inner end reduced, a hollow axle
fitting within the recess and embracing the spindle and having near its outer end
an exterior shoulder, and a nut operating with the hub box and having its inner end
directly adjacent to the shoulder, substantially as described.
Dated this 14th day of December 1896.
