page_text: LETTERS PATENT to John Septimus Ayton Civil Engineer of Stoke-upon-
Trent and Thomas Floyd Civil Engineer of 3 Victoria Mansions Westminster
for an Invention of AN IMPROVED WHEEL
PROVISIONAL SPECIFICATION left by the said John Septimus Ayton and
Thomas Floyd at the Office of the Commissioners of Patents on the 21st June
1882.
JOHN SEPTIMUS AYTON, Civil Engineer, of Stoke-upon-Trent, and THOMAS
FLOYD, Civil Engineer, of 3, Victoria Mansions, Westminster, "AN IMPROVED
WHEEL."
The improved wheel which forms the subject of this application for Letters
Patent is specially suited for tramways or railways.
The invention consists in forming the body portion of the wheel separate and
distinct from the outer or peripheral portion.
The latter portion of the wheel is provided on its outside with a flange, while on
the inner side it is provided with a ledge or shelf, on which the outer rim of the
body portion rests, and to which it is fastened by screws held by nuts, or in any
other suitable manner.
Between the ledge or shelf of the peripheral portion of the wheel and the outer
rim of the body portion, a washer of india-rubber or other suitable material may be
placed, for the purpose of deadening sound, tightening up, and lessening wear
and tear.
The body portion of the wheel may be solid, or formed of spokes, as found
convenient.
The wheel may either be keyed to the axle, or revolve upon it.

FLOYD Civil Engineer of 3 Victoria Mansions in the County of Middlesex AN
IMPROVED WHEEL
The Improved Wheel which forms the subject of this application for Letters
Patent is specially suited for Tramways or Railways as will be fully understood
from the following description in connection with the accompanying drawings
The Invention consists in forming the body portion a of the wheel separate and
distinct from the outer portion or tyre b
The former or body portion a of the wheel (which can be made of any material
and of either the "Dise" pattern as shown in the drawing or of the spoke pattern,
and keyed or allowed to run loose on the axle as may be found necessary) has at
its outer portion a facing c to receive the outer or tyre portion b of the wheel,
which portion can be made of Chilled Cast Iron or Steel
This outer portion or tyre is made with a projection or shelf d by which it is
fastened by means of bolts or rivets c to the body portion of the wheel
The body portion of the wheel is turned slightly less in diameter than the inside
diameter of the outer portion or tyre so as to allow the insertion of a washer
which washers can be made of India Rubber Felt or any other suitable material
The object of the washer is to prevent any jarring and also to enable the outer
portion of the body of the wheel to be re-tyred without being "bored" or "turned'
and it also answers the purpose of deadening the sound altogether making a much
more suitable wheel for running purposes
One advantage of this invention is that when any portion of the tyre of the
wheel becomes broken or damaged in such a way as to be of no further use instead
of pulling the entire wheel off the axle as at present by moving the bolts or rivets
it is merely necessary to take the tyre or outer portion of body of wheel off the
axle and rivet or bolt another one on
Another advantage of this improved wheel is that it prevents to a great
degree if not entirely the unpleasant ringing noise which is always heard when
cast iron or chilled "Disc" wheels are used
And having now described the nature of our said Invention and in what manner
the same is to be performed we declare that we claim The Improved Wheel
herein before described and substantially as shewn in the annexed drawings
In Witness Whereof we the said John Septimus Ayton and Thomas Floyd
have hereunto set our hands and seals this Twentyfirst day of December
1000
