County of Lanark, North Britain, Engineer, for the Invention of
T
.
Sealed the 30th December 1873, and dated the 2nd July 1873.
PROVISIONAL SPECIFICATION left by the said William Thomas
Wheatley at the Office of the Commissioners of Patents, with his
Petition, on the 2nd July 1873.
I, WILLIAM THOMAS WHEATLEY, of Glasgow, in the County of
Lanark, North Britain, Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN FASTENING TIRES ON WHEELS," to be
as follows, that is to say:-
This Invention has for its object the fastening of tires on wheels in an
improved manner, and so that a tire will not fly off even when broken in
several places.
In carrying out the Invention the tire is formed with a flange pro-
jecting inwards at one of its inner corners, and the inside face of this
flange is grooved or checked to fit on a counterpart rib formed round the

page_text: rim of the wheel frame. At the other inner corner of the tire a dove-
tailed rib is formed on it, and a similar dovetailed rib is formed round
the corresponding corner of the rim of the wheel frame. When the tire
is fixed the dovetailed ribs are grasped by flanges on an annular fastener
which may be in any convenient number of segments. This fastener is
in the form of a flat ring with flanges on its inner and outer edges,
so that it presents a channel section when cut radially, and it is applied
in a heated state with the flanges sufficiently open to pass over the
combined dovetailed ribs on the rim and tire. Inclined grooves are
formed in shaping the dovetailed ribs, and in forcing the fastener by
hammering or otherwise into its place, its flanges are made by the outer
sides of the grooves to collapse upon and grasp the sides of the dove-
tailed ribs, and so lock and hold the tire securely on the rim. The tire
and wheel rim may be grooved or indented in forming the dovetailed
ribs sufficiently for the outside of the fastener to be flush with the side
of the tire or rim, or so as to project more or less therefrom.
L
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Thomas Wheatley in the Great Scal
Patent Office on the 31st December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM :
THOMAS WHEATLEY, of Glasgow, in the County of Lanark, North
Britain, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Second day of July, in the year of our Lord
One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Thomas Wheatley, Her special
licence that I, the said William Thomas Wheatley, my executors, ad-
ministrators, and assigns, or such others as I, the said William Thomas
Wheatley, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and. Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN FASTENING TIRES ON WHEELS," upon the condition

page_text: in the form of a flat or nearly flat ring with flanges 8, 9, on its inner
and outer edges, so that it presents a channel section when cut radially.
This fastener ring 10 is applied in a heated state, and with its
flanges 8, 9, in a sufficiently open position to pass over the outer wider
parts of the combined dovetailed ribs 6, 7. Sections of the fastener
rings 10 in the form they have prior to being applied are shown between
the Figures. Inclined grooves are formed (between 6 and 11 and
between 7 and 12) in shaping the dovetailed ribs 6, 7, and in forcing the
fastener ring 10 into its place; its flanges 8, 9, are made by the outer
sides of such grooves to collapse upon and grasp the sides of the dove-
tailed ribs 6, 7, and so lock and hold the tire 1 securely on the rim 2,
the fastener ring 10 being also itself locked in place without any separate
or additional fixing detail. I prefer to force the fastener ring 10 into
its place by a rolling process, but it may in some cases be forced in by
hammering or by other means. For the rolling process there may bc
used a roller, shaped to bear on the outer corners of the fastener ring
and held by a lever or radius bar centred on the axle, or on a shaft or
stud in the position of the axle, so that the roller may be carried round,
the wheel being placed horizontally when being operated on. Tho
tire 1 and wheel rim 2 may be grooved or indented in forming the dove-
tailed ribs 6, 7, sufficiently for the outside of the fastener 10 to be flush
with the tire and rim, as shown in Figures 2 and 5, or so as to project.
more or less therefrom, as shown in Figures 1, 3, and 4.
Instead of forming the tire 1 as herein-before described with the well
known internally checked holding flange 3 at one side, my combined
dovetailed ribs 6, 7, and fastener ring 10 may be applied at both sides, as
-shown in Figures 4 and 5.
It is obvious that with my improved fastening arrangements the tire
could not leave the wheel rim, even if broken across in several places,
and this is a feature completely distinguishing my improved method
from existing plans which may slightly resemble it in other respects.
Having thus particularly described my said Invention, and the
manner of performing the same, I have to state that I do not restrict
myself to the precise details herein described or delineated, but that
what I believe to be novel and original, and claim as the Invention
secured to me by the herein-before in part recited Letters Patent is, the
fastening of tires on wheels by means of flanged rings made to combine

page_text: with dovetailed ribs formed on the tire and wheel frame, as herein-before
described.
In witness whereof, I, the said William Thomas Wheatley, have
hereunto set my hand and seal, this Thirtieth day of December,
in the year of our Lord One thousand eight hundred and seventy-
three.
Witness,
EDMUND HUNT,
