PROVISIONAL SPECIFICATION.
Improvements in Wheels for Carriages.
We, WILLIAM ROBERT WALKER of 97 Mount Street Grosvenor Square
Ironmonger and MILLS GOODEY of 79 Pentonville Road Carriage Builder both
in the County of London, do hereby declare the nature of this invention to be as
follows
The object of our invention is to provide a means for securing rubber or like
tyres upon or to the rims, metallic tyres, or peripheries of the wheels of road
vehicles, and of such a nature as to be equally applicable to wheels having specially
constructed felloes and metallic tyres or rims or to existing wheels in ordinary use
such as those of cabs, carriages, omnibuses and the like, and in carrying out our
invention we provide a rubber or like tyre of semicircular or any convenient section
but having its flat or internal face extended somewhat so as to form a small flange
on each side and this rubber or like tyre may be either endless, i.e., made in one
piece or continuous circumference of predetermined length to fit a wheel of
ascertained diameter or may be made in a continuous length of rubber or like
material and cut off to suit the diameter of various wheels. The rubber tyre
is first sprung upon the metallic tyre if the said rubber tyre be an endless one
or if continuous is temporarily secured thereto (or either may be solutioned on).
For the purpose of permanently securing the rubber tyre we provide metallic
segmental plates formed to fit the outer circumference of the felloes and of sufficient
depth to embrace the flange of the rubber or like tyre and extend downwards to
near the centre of the felloe. These plates are of L or similar section at their
outer extremities being bent inwardly or otherwise formed so as to embrace and
firmly hold the flanges of the rubber. At intervals in these plates we drill or form
countersunk holes for the heads and nuts of bolts and also form corresponding
holes through the feiloes in which bolts or like devices are inserted. These
segmental plates are fitted on each side of the felloes and cramped in position
whilst the bolts or like devices are passed through both opposite plates and the
felloe and the whole drawn closely together by keyed nuts or the like.
In some
cases we may use angle shaped circular plates in one piece, one for each side of
the wheel secured to the felloes as before described, and in making wheels specially
to be fitted with our invention the felloes may have their upper or outer portions
sunk to receive the clamps or plates so that they may be flush with the lower or
inner portion when fixed, and in place of the usual metallic tyre a thin rim or plate
may be used.
Instead of shaped plates and rubber tyres with rectangular flanges we may
find it desirable to use a section of plate having rounded internal and external
angles and a correspondingly shaped rubber or like tyre, and we may form pins
studs, or teeth on the internal face of the head of the plates so as to grip or bite
the rubber or we may form holes in the heads of the plates at intervals through
which pins or other devices may pass into or through the rubber or through both
plates and rubber being secured by nuts or the like on opposite side.

Improvements in Wheels for Carriages.
We WILLIAM ROBERT WALKER of 97 Mount Street Grosvenor Square.
Ironmonger and MILLS GOODEY of 79 Pentonville Road Carriage Builder both.
in the County of London 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 our invention is to provide a ready means for securing rubber or
like tyres upon or to the rims, metallic tyres, or peripheries of the wheels of road
vehicles and so as to be equally applicable to wheels having specially constructed
felloes and metallic tyres or rims or to existing wheels in ordinary use such as
those of cabs, carriages, omnibuses, and the like, and for the purpose of fully
explaining the nature of our said invention we have attached to this Specification a
sheet of drawings to which with the figures and letters of reference thereon we
shall hereinafter refer.
Figure 1 is a view of part of the felloe of a wheel fitted with an india rubber
tyre secured by one form of our improved means,
Figure 2 is a section through same showing the bolt or pin which secures
the plates,
Figure 3 is a section of the rubber or like tyre,
Figure 4 is a section showing another form of retaining plates and
Figure a section of rubber tyre corresponding thereto.
In carrying out our invention we provide a rubber or like tyre of convenient
section to suit the form of securing plates hereafter described and preferably such
as shown by A Figures 1, 2, 3, or B Figures 4 and 5, having flanges A¹ or B', and
this tyre may be endless, i.e., made in one piece to fit a wheel of ascertained
diameter or it may be manufactured in a continuous length so that portions may
be cut off so as to fit any wheel if found desirable. In securing the rubber tyre by
our improved means it is first sprung upon or over the metallic rim if the said
rubber tyre be an endless one, or secured temporarily thereon by means of cramps
if part of a continuous length, (or either may be solutioned on) when it is
permanently fastened by means of our invention as follows.
We provide metallic segmental or continuous plates either of section as shown
by C C in Figures 1 and 2 or as D D Figure 4 or of any equivalent section formed
to fit the outer circumference of the felloes E and of sufficient depth to embrace the
flanges of the rubber tyre and extend upwardly to near the centre of the felloe the
edges being splayed or chamfered as in Figures 1 and 2 or sunk into the felloe as
shown in Figure 4.
Countersunk holes are formed in the plates at intervals and bolts, screws, or
pins F passed through and through the felloe and secured by a nut or other device
after passing also through the opposite plate and in some cases we may pass a
second pin or its equivalent G as shown in Figure 4 through the heels of the
plates and the rubber so as to further secure the whole.
The segmental or continuous plates are placed on each side of the felloes and
cramped in position whilst the bolts or like devices F are passed through the felloes
and both opposite plates when the whole are drawn closely together by keyed
nuts H.
In applying our invention to new wheels a light thin steel or like rim may be used
in place of the ordinary heavier metallic tyre.
The metallic plates as well as securing the rubber tyres will protect the
wooden felloes and tend to keep their different sections or segments closer and more
firmly together and it will be seen that by the use of our invention ordinary wheels
may be speedily fitted with rubber tyres and without injury to them.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. For securing double flanged india rubber tyres such as A or B to the wheels
of carriages the use of 7 snaped metallic segmental or circular plates such as C
or D, or any mere equivalents therefor, substantially as herein before described and
as illustrated by the accompanying drawings.
2. In wheels of carriages the combination of india rubber or like tyres of sections
such as A or B with segmental or circular metallic plates of sections such as C
or D or any mere equivalents therefor substantially as illustrated by the
accompanying drawings.
