Improvements in Wheels for Use on Common Roads.
I, ALEXANDER SPENCER of 77 Cannon Street, in the City of London, Engineer do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct wheels for common roads that shall be
practically noiseless. For this purpose I construct such wheels to receive india rubber
tyres which I form with concentric annular grooves or recesses one at each side of the
tyre each to receive an annular rim or inwardly projecting part of a flange or retaining
ring, the arrangement being such that the tyre can be readily secured in place and
removed when necessary and when in its place on the periphery of the wheel it will
be held either between a flange and a retaining ring, or it may be between two
retaining rings; both being in each case formed as I have above described, or in an
equivalent manner, the arrangement being such that the portion of the elastic tyre
that is next or near to the rim or periphery of the wheel shall be of greater width than
some other portion thereof at a greater distance from the axis of the wheel, and which
is held between the flange and retaining ring or between the retaining rings.
By my invention, an elastic tyre can be fastened to a wheel as securely for all
practical purposes as though moulded thereon or cemented thereto.
Dated this 14th day of December 1888.

COMPLETE SPECIFICATION.
Improvements in Wheels for Use on Common Roads.
I, ALEXANDER SPENCER, of 77, Cannon Street, in the City of London, Engineer,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to construct wheels for common roads that shall
be practically noiseless. For this purpose I construct such wheels to receive india
rubber tyres which 1 form with concentric annular grooves or recesses one at
each side of the tyre each to receive an annular rim or inwardly projecting part of a
flange or retaining ring, the arrangement being such that the tyre can be readily
secured in place and removed when necessary and when in its place on the periphery
of the wheel will be held either between a flange and a retaining ring, or it may be
between two retaining rings; both being in each case formed as I have above
described, or in an equivalent manner the arrangement being such that the portion of
the elastic tyre that is next or near to the rim or periphery of the wheel shall be of
greater width than some other portion thereof at a greater distance from the axis
of the wheel and which is held between the flange and retaining ring or between the
retaining rings.
In the accompanying sheet of illustrative drawings
Fig. 1 is a central vertical section of a wheel constructed according to this
invention.
Fig. 2 is an elevation of one half of such a wheel as seen from the inner side with
the bolts 8 removed.
1 is an india rubber tyre arranged to encircle the wheel rim 2. This tyre is
formed at each side with an annular groove or recess 3. 4 is a flange forming
part of the wheel body, and made with an annular inwardly projecting rim or
part 5; the rim or part 5 is arranged to be received in one of the grooves or recesses 3
5 Price Gil

page_text: in the tyre. 6 is a retaining ring formed with an annular inwardly projecting rim or
part 7 that enters the other groove or recess 3 in the tyre. This retaining ring is
made removable and may for this purpose be secured by bolts 8 and nuts, as shown,
to that side of the wheel which, when the wheel is in use, becomes the outer side.
The width of that part of the elastic tyre that is to be clamped between the flange 5
and retaining ring may advantageously be such that when fastened in place this part
of the tyre will be slightly compressed.
By the arrangement described and shown an elastic tyre can be fastened to a
wheel as securely for all practical purposes as though moulded thereon or cemented
thereto, and it can, moreover, be readily and quickly removed when worn and
replaced by a new tyre.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. A wheel for use on common roads, constructed with an elastic tyre secured in
place between a flange on the wheel rim and a removable retaining ring, or between
two retaining rings, the flange and ring, or the rings as the case may be, being
constructed with inwardly projecting parts and the arrangement being such that the
portion of the elastic tyre that is next or near to the rim or periphery of the wheel is
of greater width than a portion thereof at a greater distance from the axis of the
wheel and which is held between the flange and retaining ring, or between the
retaining rings, substantially as herein before described for the purpose specified.
2. My improved wheel with elastic tyre as described and shewn.
