der f cuts into the packing material k as the
locking and packing nut q is screwed onto
the packing sleeve h and into the hub cas-
ing rm at p, thereby compressing the packing
5 material k between the said nut q, the. annu-
lar head or flange j of packing sleeve h and
the cylindrical end t of spindle box forcing
the compressed packing material to fit
closely against the extended annular knife
10 edged flange g of spindle shoulder f, thus
preventing the entrance of dust or water into
the interior of the assembled wheel hub, and
preventing the lubricating oil from leaking
out.
15 The spindle box, spindle and packing
sleeve may be fitted to other forms of wheels,
thereby preventing the entrance of dust or
water and the leaking out of lubricating oil,
and with similar constructions, any wheel-
20 hub bearings may be made absolutely self-
lubricating and dust-tight.
My invention is assembled in the follow-
ing manner :-The packing sleeve h is placed
around the portion a of the axle and secured
25 in stationary position by the screw 9 or any
auxiliary coupling. The spindle box shown
in Fig. 3 is then slipped onto the spindle b
and the spindle nut d is screwed home and
fastened with the set screw e. The wheel
30 hub is then slipped on over said spindle box
and the cap nut r screwed home, thereby
locking said spindle box securely in the hub.
The packing k is then placed around the
sleeve h and forced into the interior of the
35 hub casing im, the spring S is placed over the
sleeve h, and the locking and packing nut q
is then placed around the packing sleeve ht
and turned with a wrench so as to travel
along the screw-threads i and into the hub
40 casing m, engaging also the screw-threads p,
thereby compressing the packing material k
between the flange or head j of the packing
sleeve I, the end t of the spindle box, and
the spring S engaged by the locking and
45 packing nut q, thereby forcing the com-
pressed packing material k against the an-
nular extended knife edged flange g of the
spindle shoulder f and to also cover over and
securely close the joints between the end t
50 of spindle box and the interior of hub cas-
ing rn, and between the end t of the spindle
box, and the spindle shoulder f. The pack-
ing sleeve h is then released by removing
or loosening the screw 9 or other auxiliary
55 fastening, and the whole wheel hub, together
with its packing sleeve h, its compressed
packing k, and spindle box, is free to revolve
or rotate on the spindle and axle. Before
using the vehicle on which such wheel hubs
60 are mounted, however, the screw 1 should
be removed and the interior filled with lu-
bricating oil and the screw then replaced.
By this means the interior of the wheel hub
will be thoroughly lubricated, the spaces be-
65 tween the flanges or ribs y being filled withoil which enters through the grooves x. And
the compressed packing material covering
and pressing over the joints between the in-
terior of the hub casing m and the end t of
the spindle box and the bearing joint be- 70
tween the end t of the spindle box and the
spindle shoulder f, aided by the knife edged
flange g protruding and cutting into the
compressed packing material k, absolutely
prevents the oil from leaking out, or dust or 75
water from entering therein. And since the
screw 9, or any auxiliary fastening, holds
and secures the packing sleeve h in position
until the packing k is compressed and said
packing sleeve h, together with the packing 80
k, and the flange or head j is securely locked
to the hub casing m by the locking and pack-
ing nut q, and the packing sleeve h is thus
prevented from touching any portion of the
axle a or spindle b; and the compressed 85
packing material Jo is prevented by the an-
nular flange or head j of the packing sleeve
h from touching any portion of the spindle
shoulder f except the sharp annular knife-
edged portion of flange g, there is absolutely 90
no friction engendered by the use of the
packing material k, except the very small
portion caused by the sharp circular edge of
said flange g cutting into the compressed
packing material, which is comparatively 95
negligible. And since the packing material
k is compressed between the flange or head
j of the packing sleeve, the end t of the spin-
dle box and the spring 8 engaged by the
locking and packing nut q, thereby securely 100
closing and guarding the joints between the
end t of spindle box, the interior of hub
casing m and the bearing joints between the
end t of spindle box and the spindle shoulder
f, it is-absolutely impossible for lubricating 105
oil to escape from the inner bearings, or for
dust or water to enter therein through said
compressed packing material k. Hence it is
only necessary that the extended, annular
sharp knife-edged portion of flange g of the 110
spindle shoulder f be made to extend out
even or flush with the end t of the spindle
box and the flange or head j of the packing
sleeve, in order to exclude dust and water
and prevent the escape of lubricating oil, 115
from the inner bearings of the assembled
wheel hub by way of said compressed pack-
ing material. But in order to compensate
for any play or lateral motion given to the
wheel hub on the spindle, I prefer the ex- 120
tended annular sharp knife-edged portion
of said flange g of the spindle shoulder f to
cut and extend into the compressed packing
Jo about one-sixteenth of an inch beyond the
end t of the spindle box and the flange or 125
head j of the packing sleeve, as represented
in Fig. 1. Hence the packing material (as
represented by k) is one of the very impor-
tant parts of my invention, when thus in-
stalled, in the capacity of excluding dust 130a
