I, JARRATT LIVERSIDGE, 196, Old Street, London, Coach Builder, do hereby
declare the nature of this invention to be as follows:-
-
My improvements consist in forming the nave or stock of wheels for road or
other vehicles with a built up wooden centre which is constructed in the following
manner. I employ a series of double wedge shaped segments, which when.
pressed together and secured by flange plates screwed or bolted together, form
a solid nave, stock, or hub into which the spokes can be driven or removed with-
out however disturbing in any way the component parts of the hub, or the other
spokes. These segments are so made as that their innermost or central portions wedge
tightly against each other thus forming practically a solid centre suitable for
boxing, the foot of each spoke being so tapered as to form a perfect fit with the
outer portion of the wedges on either side of it. In same cases I may use a cross
tenon at the foot of each spoke, which engages with a suitable mortice or slot
so formed in the shoulder of the wedge on either side of it as that it tends to key
or lock them together.
When the wedges and spokes are fitted together and the felloes placed in posi-
tion the wheel is consolidated by pressure, the nave or hub being rigidly secured
by two metallic flange plates which are bolted or screwed together, the bolts in
preference passing through each segment. By altering the angle of one or both
of the flange plates a wheel thus constructed may be dished. By tapering the
horizontal portion of the inside of the flange plates and filling with wood the
wheel can be made suitable for boxing with an ordinary axle box.
Dated this 2nd day of June 1899.

I, JARRATT LIVERSIDGE, 196, Old Street, London, E.C., Coachbuilder, do hereby
declare the nature of this invention and in what manner the same is to be per-.
formed to be particularly described and ascertained in and by the following
statement:-
My improvements consist in forming the nave or stock of wheels for road or

page_text: other vehicles with a built-up wooden centre which is constructed in the follow-
ing manner: I employ a series of double wedge shaped segments which when
pressed together and secured by flange plates screwed or bolted together form a
solid nave, stock, or hub into which the spokes can be driven or removed without
however disturbing in any way the component parts of the hub, or the other
spokes. These segments are so made as that their innermost or central portions
wedge tightly against each other thus forming practically a solid centre suitable
for boxing, the foot of each spoke being so tapered as to form a perfect fit with
the outer portion of the wedges on either side of it. In some cases I may use a
cross tenon at the foot of each spoke which engages with a suitable mortice or
slot so formed in the shoulder of the wedge on either side of it as that it tends
to key or lock them together.
:
When the wedges and spokes are fitted together and the felloes placed in
position the wheel is consolidated by pressure, the nave or hub being rigidly
secured by two metallic flange plates which are bolted or screwed together the
bolts in preference passing through each segment. By altering the angle of one
or both of the flange plates a wheel thus constructed may be dished. By tapering
the horizontal portion of the inside of the flange plates and filling with wood
the wheel can be made suitable for boxing with an ordinary axle box.
I will now describe my invention more particularly by means of the accom-
panying drawings in which:
Fig. 1, is a front elevation of the wheel with flange plate removed.
Fig. 2, is a perspective view of segment.
Fig. 3, is a perspective view of spoke.
Fig. 4, is a sectional plan on line A B Fig. 1.
Fig. 5, is a section of flange plates.
Similar figures refer to similar parts in all the views.
1, is one of the double wedge-shaped segments which is grooved or recessed
on either side of each shoulder as at 2, and bored for the bolt as at 3.
The exterior of each segment is slightly rounded as at 4, so as to preserve the
external contour of the stock or nave. 5, Fig. 3, shews a spoke; this is turned
or otherwise tooled to the usual rounded or other shape 6, at its outer end so as
to fit a corresponding hole or mortice 6 in the felloe. The inner end of each
spoke is wedge shaped as at 7, on either side, the taper being the same as that
formed upon the outer part of each segment as at 71, and at the foot I may form
a cross tenon 2¹, which exactly fits the half mortice or recess 2, formed on
either side of each segment.
Each flange plate 8, which is usually a casting in malleable iron, gunmetal,
steel, or other suitable metal, or may be stamped welded up or otherwise formed
is drilled with a series of holes 3', so as to exactly correspond with those formed
in the segments, the horizontal portion of each plate being tapered as at 81 and
filled in with wood 9. The wheel is built up as follows:-A series of segments
and spokes are ranged in order. The rounded or other shaped end of each spoke
is next inserted in the corresponding hole formed in the felloe, the whole of
which as well as the spokes are then forced inward by pressure. The plates are
then bolted, as at 10, or riveted on. If the wheel is to be built with straight
spokes, the flanges of both plates will be square with their horizontal axis.
If however the spokes are to be dished the flange of the outer plate 11, is
bevelled as at 81, to the dish of the spoke and that part of the segment against
which the flange plate comes is shaped so as to be flush with the spoke. The
hinder portion of foot of spoke being cut to bevel of dish.
It will be seen that by means of my invention as old spoke can be taken out
and replaced, as in the case of an ordinary wheel without however destroying the
solidarity of the hub. Moreover as the segmental tapering is radial it follows
that the central portion of the nave, stock, or hub although built up in the
manner described is wedged by the pressure so tightly together as to form practi-
eally a solid wooden centre.

page_text: For a similar reason it is obvious that the spokes are firmly keyed in position,
but as no bolt passes through them the strength of their whole section is secured.
The horizontal portion of the metal flange plates is tapered and fitted with wood,
when any ordinary form of axle box is employed. The usual forms of metal hub,
flange, or flange and hub combined, or metal hub and box combined, or metal
Hange and box combined can be used so long as part of any one of the above
forms the necessary Hange to cover the feet of the spokes and the wedging of
the spokes and segments is not interfered with.
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. The combination in or with a wheel for road vehicles of a stock nave or
hub composed of double wedge-shaped segments recessed or grooved on either side
of the shoulder and the spokes tapering as shewn and having a cross tenon at
foot which engages with grooves in said segments, with flange plates having
the inner diameters of their horizontal portion greater than the outer for the
purpose of securely retaining a wood core, said flange plates being fastened by
bolts or rivets passing through holes formed in them and the segments in the
manner herein set forth.
2. The combination in or with a wheel for road vehicles having a stock nave
or hub as described in the foregoing specification and claimed in Claim 1, of a
flange plate the inner rim or flange of which is bevelled to dish of spokes.
3. In a wheel for road vehicles the combination of parts herein described co-
operating for effecting the purpose specified.
