page_text: I JOSEPH CROSS of No 67 Franchise Street Wednesbury in the County of
Stafford Pattern Maker do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF WHEELS FOR RAILWAY AND TRAMWAY
CARRIAGES AND FOR OTHER PURPOSES to be as follows:-
"
My invention has for its object to manufacture a strong wheel which produces
but little noise in use and in which the accidental fracture of the tyre is not
attended with the serious consequences which commonly follow the breaking of the
tyre of a railway or other wheel of the ordinary manufacture.
My improvements are especially applicable to the manufacture of wheels for
railway and tramway carriages but are also applicable to the manufacture, of
wheels for other purposes such for example as the wheels of traction engines and
wheels or pulleys for driving machinery.
I will describe my invention in connection with the manufacture of a railway
carriage wheel.
I form the tyre separate from the middle part of the wheel and preferably of enst
steel. On the inner face of the tyre is a slightly projecting rib extending all round.
This rib has six or other number of equi distant projections or snugs in each of
which snugs a hole is made through which holes the screw bolts pass which connect
the parts of the wheel together as hereinafter explained.
The middle part of the wheel is made of two nearly similar parts fixed to the
tyre by screw bolts. These middle parts consist of a rin with spokes and a central
boss for the axle. The spokes are not radial but are inclined the spokes of one of
the parts being inclined in the opposite direction to those of the other part.
These two parts are placed respectively on opposite sides of the tyre and bear
upon the rib on the inner face of the tyre The said parts have the same number
of equidistant holes as the tyre and the said two parts are fixed to the tyre by
screw bolts passed through holes in the said parts and in the tyre. The bolts are
fixed by screw nuts.
In order to reduce to a minimum the noise produced in the working of the
wheels I put a ring or washer of india rubber or other elastic or flexible material
between each of the rings of the side parts and the rib on the inner face of the
tyre on which rib the said rims bear. And I also fill the middle of the tyre with
wood cut to fit the interior of the tyre and of a thickness equal to the combined
thicknesses of the rib and the two washers of india rubber.
In place of wood for filling the middle of the tyre felt or papier-mâché or other
fibrous material may be employed.

page_text: I JOSEPH CROSS of No 67 Franchise Street Wednesbury in the County of
Stafford, Pattern Maker, do hereby declare the nature of my Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF WHEELS FOR RAILWAY AND TRAMWAY
CARRIAGES AND FOR OTHER PURPOSES " and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention has for its object to manufacture a strong wheel which produces
but little noise in use and in which the accidental fracture of the tyre is not
attended with the serious consequences which commonly follow the breaking of the
tyre of a railway or other wheel of the ordinary manufacture.
My improvements are especially applicable to the manufacture of wheels for
railway and tramway carriages but are also applicable to the manufacture of wheels
for other purposes such for example as the wheels of traction engines and wheels or
pulleys for driving machinery.
I will describe my invention in connection with the manufacture of a railway
carriago wheel.
I form the tyre separate from the middle part of the wheel and preferably of
cast steel. On the inner face of the tyre is a projecting rib extending all round.
This rib has six or other number of equidistant projections or snugs in each of
which snugs a bole is made through which holes the screw bolts pass which connect
the parts of the wheel together as berein-after explained.
The middle part of the wheel is made of two nearly similar parts fixed to the
tyre by screw bolts. These middle parts consist of a rim with spokes and a central
boss for the axle. The spokes are not radial but are inclined the spokes of one of
the parts being inclined in the opposite direction to those of the other part.
These two parts are placed respectively on opposite sides of the tyre and bear
upon the rib on the inner face of the tyre. The said parts have the same number
of equidistant holes as the tyre and the said two parts are fixed to the tyre by
screw bolts passed through holes in the said parts and in the tyre. The bolts are
fixed by screw nuts.
In order to reduce to a minimum the noise produced in the working of the
wheels I put a ring or washer of india rubber or other elastic or flexible material
between each of the rims of the side parts and the rib on the inner face of the tyre
on which rib the said rims bear. And I also fill the middle of the tyre with wood
cut to fit the interior of the tyre and of a thickness equal to the combined
thicknesses of the rib and the two washers of india rubber.
In place of wood for filling the middle of the tyro, felt or papier-mâché or other
fibrous material may be employed.
Figure 1 of the accompanying Drawings represents in side elevation and
Figure 2 in vertical section a railway carriage wheel constructed according to
my invention; Figure 3 represents in vertical section the tyro separately and
Figure 4 in vertical section and Figure 5 in front elevation one of the two parts
of which the side or middle parts of the wheel are composed.
The same letters of reference indicate the same parts.
a is the separate tyre of the wheel made by preference of cast steel the said tyre
having on its inner face a projecting rib b extending all round. In the said rib
and at equal distances apart six (or other number of) holes o, c are made for
receiving the scrow bolts d d. The said internal rib b, may be made of the same

page_text: breadth throughout or projections or snugs of the kind represented in the side parts
of the wheel (see Figures 1 and 5) may be made on the internal rib b, in which case
the holes for the screw bolts are made in the said projections or snugs. Each of
the said side or middle parts of the wheel consists of a rim e with inclined or non-
radial spokes fand a central boss g for receiving the axle. The said side or middle
parts efg; e, fg are connected to the tyre a by the screw bolts and nuts d, d.
It will be seen by an examination of Figure 2 that the boss of one of the side or
middle parts e, f, g is longer than that on the other side or middle part. It will
also be seen by an examination of Figure 1 that the spokes of one of the side parts
are inclined in the opposite direction to those of the other part. In the snug parts
of the rims e of the side pieces holes, h h are made similar in number and position
to the holes c c in the tyre a for the fixing screw bolts d, d to pass through; i is a
piece of wood papier-mâché, felt or other non-metallic material for filling the
interior of the tyre a the said filling piece i having the same thickness as tho
projecting rib 6 of the tyre.
In building up the wheel the wooden filling piece i is first placed in the interior
of the tyre a and the side or middle parts efg; e f g of the wheel are then
respectively placed on opposite sides of the tyre and made to bear upon or against
the internal rib b of the tyre in the manner represented in Figure 2, the said side
parts being so arranged with respect to the tyre that the holes h h in them coincide
with the holes c, c in the internal rib b of the tyre. The snugs of the two side
parts e, f, g slightly overhang the wooden filling piece i and the bosses g, g of the
said side parts embrace or enclose the inner edge of the said filling piece i (see
Figure 2). After the four parts of which the wheel is composed have been thus
arranged they are connected together by passing the scrow bolts d, & through the
holes h, h and c in the side pieces and tyre and fixing the said bolts by scrow
nuts as represented. A ring or washer of india rubber or other clastic or flexible
material may be placed between each of the rims e of the side parts e, f, g and the
rib b of the tyre for further reducing the noise produced in the working of the
wheels. These washers are not represented in the drawing.
I construct wheels for tramway carriages, wheels for traction engines and wheels
or pulleys for driving machinery and for other purposes substantially in the
manner herein before described and illustrated with respect to a railway carriage
wheel.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
Manufacturing wheels for railway and tramway carriages and for other purposes
of a separate tyre having an internal rib with a filling piece of wood or other
non-metallic material, and two side or middle parts, each side or middle part
consisting of a rim, spokes and boss, the said tyre and the side or middle parts,
with the filling piece of the tyre, being connected together by screw bolts and
nuts substantially as herein before described and illustrated in the accompanying
Drawing.
