the inner ends fit between the flanges y
hereinafter described. The inner end of the
hub-casing is screw-threaded, as shown at p,
and the locking and packing nut q, engages
5 the screw-threaded portion p and also the
screw-threaded portion' i of the sleeve h.
The outer end of the hub casing is screw-
threaded and closed by a. cap nut r, which
cap nut screws into the interior of the outer
10 end of said casing. This cap nut r also
screws over the screw-threaded end of the
spindle box hereinafter described.
A side view of the spindle box is shown in
Fig. 3, and it consists of a hollow cylindrical
15 portion t, which surrounds the cylindrical
spindle shoulder f of the spindle b. One
end of the hollow cylindrical portion t is
partially closed, by a portion i, centrally
perforated, as shown at v. This spindle box
20 is also provided with a cylindrical extension
'iL, centrally perforated, and adapted to fit
over the spindle b. The said cylindrical.
portion w is provided with annular oil
grooves x, which grooves x are cut through
25 the cylindrical surface of the portion w, in-
tersecting the oil pockets that are situated
between the radial ribs or flanges y, which
flanges y extend outwardly from the cylin-
drical portion w, and are fitted into the inner
30 tubular surface of the hub casing, thereby
providing pockets for lubricating oil be-
tween said ribs or flanges y, the inner tubu-
lar surface of the hub-casing and said cy-
lindrical portion w of the spindle box.
35 These pockets may be occasionally filled
with lubricating oil, thus insuring constant
lubrication. The outer ends of the horizon-
tal ribs y are reduced and screw-threaded, as
shown at :, to engage with the screw-threads
to on the inner part of the cap nut r, which cap
nut r thus screwing into the casing and onto
the ribbed end of the spindle box, at the
same time, secures the spindle box in posi-
tion in the assembled wheel hub. Through
45 the hub casing pass bolts or screws 1 and 2,
which firmly lock the casing and the cylin-
drical part w of the spindle box together.
3 and 4 represent screws or bolts that ex-
tend through the hub casing and into the
,0 cylindrical portion of the spindle box, but
since the cap nut r secures the spindle box
in position in the assembled wheel hub, the
screws or bolts 2, 3 and 4 may be omitted
and the pockets between the ribs y and the
55 interior portion of the assembled wheel, hub
may be supplied or filled with lubricating
oil by pouring the oil through the opening
made by the removal of the screw or bolt 1,
which screw or bolt 1 may be replaced after
60 the assembled wheel hub is filled with lubri-
cating oil.
9 represents a removable screw which is
used in the assemblage of my invention, and
is only intended for temporary use, and any
65 desirable screw-threaded device, lock orcoupling may be substituted therefor or
used in connection therewith.
Referring to Figs. 1 and 6, the locking
and packing nut q is split, as shown, and is
composed of two parts mounted on the rod 70
or pin 7, and the parts of said nut are also
provided with indentations 6, into which a
spanner wrench may be inserted, but if pre-
ferred the locking and packing nut q may
not be split as shown in Fig. 6, but it ina.y 75
be made in one integral annular nut and
slipped onto the axle a before the spindle b
is secured thereto. The nut q in Fig. 5 is
the same as that in Figs. 1 and 6, but in the
modified form shown in Fig. 5 the spring S 80
is omitted.
The locking and packing nut i may be
screwed onto the packing sleeve h, thereby
compressing the packing ic between said
spring 8 engaged by the nut q and the flange 85
or head j of the packing sleeve It, before the
parts are screwed into the hub casing m,
and by thus assembling them and securing
the packing nut q and the sleeve A to-
gether-with the packing le and spring be- go
tween them-they may be screwed into the
end of hub casing m, engaging the screw-
threads p and thereby press the packing
1e against the end t of spindle box and the
sharp annular flange g of the spindle shoul- 95
der, to exclude dust and prevent the escape
of lubricating oil from the inner bearings,
just the same as when the packing sleeve It
is secured in stationary position with the
screw and coupling 9. Therefore if it is 100
preferred to make the locking and packing
nut q integral (or not split) and it is pre-
ferred to assemble and secure said integral
nut q, sleeve t, spring 8 and packing k to-
gether, before screwing them into the hub 105
casing m, against the end t of spindle box
and the extended flange g of spindle shoul-
der, the screw and coupling 9 may be omit-
ted. Hence it is obvious that the packing 1
may be compressed against the end t of the 110
spindle box and the flange q of the spindle
shoulder, either with or without the aid of
the screw 9. This locking and packing nut
q is adapted to engage with the screw-
threaded portion i of the packing sleeve A, 115
and the internally screw-threaded portion of
the inner end of the assembled wheel-hub at
p, thereby locking the packing sleeve A to-
gether with its flange or head j, and the
compressed packing k, firmly to hub-casing 120
nm, while the screw 9 and any auxiliary cou-
pling holds and secures the said packing
sleeve A and its flange or head j in station-
ary position, while the said locking and
packing nut q compresses the packing I; by 125
being screwed onto the packing sleeve aind
into the hub casing m engaging the screw-
threads i and p.
It should be noted that the extended annu-
lar knife edged flange g of the spindle shoul- i3n
