WILLIAM HENRY KITSON, of Beechgrove, Oulton, Leeds, in the County of York,
Civil Engineer. "IMPROVEMENTS IN RAILWAY WHEELS."
My improvements in railway wheels consist of certain modes of fixing a cushion
between the tyre and inner frame or centre of the wheel.
The annexed Drawing shows some means of effecting this, but I do not confine
myself to the precise forins shown.
A is the tyre; a, the flange on the inner circumference of the tyre; B, the wheel
centre; C, the cushion of wood, paper, or other suitable material; D, the loose ring
or rings; and E, the bolts.

IMPROVEMENTS IN RAILWAY WHEELS."
"
My improvements in railway wheels refers to the fixing a cushion between the
tyre and inner frame or centre of the wheel, and consists in the combination with a
metallic wheel centre somewhat less in diameter than the tyre, and of a tyre flanged
at one side of its inner circumference and grooved at or near the other side of its
inner circumference, and a cushion of wood, paper, or other similar material inter-
posed between the outer circumference of the wheel centre and the inner circumn-
ference of the tyre, and a ring let into the groove or recess in the tyre and overlapping
the side of the wheel centre, the whole so arranged as to securely hold the cushion
in place between the wheel centre and tyre, and to keep the wheel centre free from
the tyre so as to throw all the weight on the cushion.
Wheel centres, tyres, and rings of various sections may be employed in carrying
out my Invention as above set forth. The rings may be formed with one or more
lips, and in some cases bolts or rivets may be passed through the ring, cushion, and
flange, and the inner circumference of the tyre. Sometimes a ring may be applied
at each side of the wheels.
Referring to the accompanying Drawings, Fig. 1 shows in section a tyre A with
a flange a round the inner circumference at or near the outside edge of the tyre,
which flange is made with a groove or lip, as shown.
Having placed the iron centre B and cushion C (which is made of wood, paper,
or other suitable material) inside the tyre, I secure thein by a loose ring D fitting
into a groove in the tyre and having a lip overlapping the wheel centre, as shown.
I then hammer down the inner edge of the tyre, so as to secure the ring in position ;
or I proceed as described above, but instead of hammering down the tyre to secure
the ring in position I pass a sufficient number of bolts or rivets through the inner
flange of the tyre, the cushion, and the loose ring.
In Figs. 2, 3, 4, 5, 6, 7, and 8 of the accompanying Drawings I have shown some
modifications of the above mode of carrying out my Invention in each of these
views. A is the tyre; a, the Hange round the inner circumference of the tyre;
B, the iron frame or centre; C, the cushion of wood, paper, or other inaterial; D, the
loose ring, made either plain, or with a lip or dovetail, or both.
In Figs. 6 and 7 bolts or rivets E are used for securing the whole together.
What I claim is, the combination in a railway wheel of a tyre formed with a
flange round the inner circumference, a metallic wheel centre, a cushion of wood,
paper, or other suitable material interposed between the said tyre and wheel centre,
and a loose ring (or rings), the whole secured in position, substantially as and for
the purpose specified.
In witness whereof, I, the said William Henry Kitson, have hereunto set
my hand and seal, this Tenth day of May, in the year of our Lord One thou-
sand eight hundred and seventy nine.
WILLIAM HENRY KITSON. (L.S.)
