PROVISIONAL SPECIFICATION.
An Improved Wheel Hub for General Purpose Carts and other
Vehicles.
་.
I, LEONARD MADGEN, of 64, Salisbury Terrace, Darlington, in the County of.
Durham, Joiner and Wheelwright, do hereby declare the nature of this inven-
tion to be as follows:
The hub may be made in cast iron, cast steel, or cast annealed iron, and
cast in one piece only, and is ready for the wheelwright when it leaves the foundry,
no fitting work being required. The shape of the hub (as shown in the accom-
panying drawings) is the same as an ordinary wooden hub, and is hollowed
out to reduce the weight of metal and to receive a ring of wood. (L and L')
Fig. 3, 4, 5, 8, at each end, in which an axlebox Z Fig. 5 is fixed. The lip N
Figure 5, secures the rings L and L¹, Fig. 3, 4, 5, 8, from working outwards after
the box is fixed, with wooden wedges M, Fig. 4, 5, 8. The projecting ribs U
Fig. 3, 8, are to prevent the rings of wood rotating in the hub, and the ring L'.
Fig. 3, 5, 8, is groved to fit the ribs of axle box and is continued through the
metal at X Fig. 5. to prevent the box rotating in the hub.
The box when badly wore may be replaced with a new one without injury to
the hub.
The two holes O Fig. 1, 2, 5, are convenient for removing and replacing the
linch pins when required:
The recesses T Fig. 2, 5, 6, are for 12 wooden spokes and the metal between
spokes is reduced as shown at P Fig. 5, 7, which also forms a key to the spokes
by slightly expanding into the cavity P, Fig. 5, 7.
The face of the spoke recess T Fig. 2, 5, 6 is tapered to suit the dish of
the wheel.
The four brackets R Fig. 4, 5, are to strengthen the rim, S, Fig. 4, 5.
The four holes V Fig. 3, provide air for the core in casting and the sand core W,
Fig. 5, 8, can be cleared from them.
The cavity Y Fig. 5, protects the end of axle and brass cap if any.
The spoke recesses T Fig. 2, 5, 6, may be made to suit various sections and
number of spokes, and the hub may be made larger or smaller than shown in the
accompanying drawings.

page_text: tion 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 an improved wheel hub for general purpose carts
and other vehicles, I make the hub in cast iron, cast steel, or cast annealed iron,
in one casting and in order that my invention may be fully understood I illustrate
it by means of two sheets of drawings left with my Provisional Specification.
Fig. 1, is a front elevation. Fig. 2 is a side elevation, Fig. 3 is a back
elevation.
Fig. 8, is a section at GH.
The form of the hub is about the same as an ordinary wooden one, and it is
made hollow to reduce the weight of metal, and to receive a ring of wood (L
and L Fig. 3, 4 and 5.) at each end which may be in one or more pieces and in
which an axle box is fixed.
In Fig. 5, the projecting circular lip N, makes the rings of wood secure, and
prevents them working outwards after the box is fixed with wooden wedges M.
(Fig. 4, 5 and 8).
In Fig. 3, and 8 the ribs U prevent the rings of wood rotating in the hub.
In Fig. 3, 5 and 8, the ring of wood L' is grooved to fit the ribs of an axle box,
and the groove is continued through the metal at X (Fig. 5) to prevent the box
rotating in the hub.
In Fig. 1, 2 and 5, the two holes O are convenient for removing and replacing
the axle pins when required.
In Fig. 2, 5 and 6, are recesses T for twelve spokes and the metal between
spokes is reduced as shewn at P, (Fig. 5 and 7), which also form a key to the
spokes by slightly expanding into the cavity P and the faces of the spoke
recesses T are made to suit the dish of the wheel, and the recesses T may also
be made to suit various sections and number of spokes.
In Fig. 4 and 5, the four brackets R are cast on to strengthen the rim S.
In Fig. 3, the four holes V provide air to the core W, (Fig. 5 and 8,) in casting,
and the core is cleared out from them.
In Fig. 5 the cavity Y protects the end of axle and brass cap if any.
The hub may be large or small according to the kind of vehicle required.
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. Casting a wheel hub in one piece of metal, with spaces provided for the
reception of rings of wood in which an axlebox is fitted and held secure by a
projecting circular lip N (Fig. 5) after being wedged with wooden wedges M,
as shown and described with reference to Fig. 4, 5 and 8.
2. Forming a cavity P in which the spokes slightly expand, and which will
prevent the spokes lifting and becoming loose, after being driven or pressed into
place, as shewn and described with reference to Fig. 5 and 7.
Dated this 28th day of May 1900.
