PROVISIONAL SPECIFICATION.
Improvements in Wheels for Vehicles.
We, JOHN HARRINGTON of the Enamel and Cradle Spring Works, Coventry, in
the County of Warwick, Manufacturer, and JOHN HOPPER of 398 Fulham Road, in
the County of Middlesex, Manager, do hereby declare the nature of this invention to
be as follows:-
The invention has for its object improvements in wheels fitted with rubber tyres.
For this purpose we employ a hollow felloe of D section, the flanges of which stand
in a vertical direction and, combined with the cross bar or plate, form a recess to
receive the tyre. We form the tyre preferably of two kinds of rubber, the part lying
within the recess being of hard rubber, and the exterior part of comparatively soft
rubber. We form the said rubber tyre with a continuous dovetailed or T shaped
recess or space opening on the underside of the tyre and forming a continuous
Darrow slot or opening therein. In this recess or space we place either a continuous
strip of metal of corresponding section or a number of short sections of such metal,
from which, according to one arrangement, screwed pins project through the before
mentioned slot.
The tyre thus fitted, and formed either in one continuous piece or in several sections,
is placed in position within the groove in the felloe, and, when the metal strips
within the recess or space in the tyre carry screwed pins, these latter are passed
through holes previously formed in the outer and inner peripheries of the felloe.
Nuts applied to the screwed pins, and bearing against the inner periphery of the
felloe, securely hold the tyre in position in the recess in the felloe of the wheel.
According to another arrangement, we place a plain strip or sections of metal in
the groove of the tyre, and we drill holes through the inner and outer peripheries of
the felloe into the metal strip or sections, which latter we form with tapped holes to
receive screws passed into the same through the holes in the felloe.
By these means the tyre is held much more securely in the felloe than by the
means heretofore adopted, and we are enabled to produce a wheel with a rubber
tyre at a cheaper rate than when employing a felloe with a deeper recess to receive
the tyre.

We, JOHN HARRINGTON of the Enamel and Cradle Spring Works, Coventry, in
the County of Warwick, Manufacturer, and JOHN HOPPER, of 398 Fulham Road, in
the County of Middlesex, Manager, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and

page_text: For this purpose we employ a felloe of D section, the flanges of which stand in a
vertical direction and, combined with the cross bar or plate, form a shallow recess to
receive the tyre. We form the tyre preferably of two kinds of rubber, the part lying
within the recess being of hard rubber, and the exterior part of comparatively soft
rubber. We form the said rubber tyre with a continuous dovetailed or T shaped
recess or space opening on the underside of the tyre and forming a continuous
narrow slot or opening therein. In this recess or space, we place either a continuous
strip of metal of corresponding section, or a number of short sections of such metal,
from which, according to one arrangement, screwed pins project through the before-
mentioned slot.
The tyre thus fitted, and formed either in one continuous piece or in several sections,
is placed in position within the groove in the felloe, and when the metal strips within
the recess or space in the tyre carry screwed pins, these latter are passed through
holes previously formed in the cross bar or periphery of the felloe. Nuts applied
to the screwed pins and bearing against the inner periphery of the felloe securely hold
the tyre in position in the recess in the felloe of the wheel.
According to another arrangement, we place a plain strip or sections of metal in
the groove of the tyre, and we drill holes through the periphery of the felloe into
the metal strip or sections, which latter we form with tapped holes to receive screws
passed into the same through the holes in the felloe.
By these means the tyre is held much more securely in the felloe than by the means
heretofore adopted, and we are enabled to produce a wheel with a rubber tyre at a
cheaper rate than when employing a felloe with a deeper recess to receive the tyre.
And in order that our said invention may be more clearly understood and readily
carried into effect, we will proceed, aided by the accompanying drawings, more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a cross section through the felloe and tyre of a wheel showing our
invention applied thereto, Figure 2 is a section through the tyre separately, Figure 3
is a section through the metal strip c, and Figure 4 represents a slight modification.
a is the felloe, which is made of D or trough shaped iron or steel, and has the flanges
thereof standing in a vertical direction. b is a rubber tyre, the part b¹ of which is
made of comparatively soft rubber, and the part 63 occupying the recess in the felloe
of harder rubber. Within the part 6 we form a T shaped, or it may be a dovetailed,
recess or space 63, which opens on the underside of the tyre, and there forms a con-
tinuous narrow slot or opening 6* therein.
In this recess or space ³, we place either a continuous strip of metal c of corre-
sponding section, or a number of short sections of such metal, from which, according
to the arrangement shown at figure 1, screwed pins c¹ project through the slot or
opening 6. The tyre 6 thus fitted and formed in one continuous piece or in several
sections, is placed in position within the groove or recess in the felloe a, and the
screwed pins c¹ are passed through holes a¹ previously formed in the felloe a, after
which nuts d screwed on to the pins c¹ and bearing against the inner periphery of
of the felloe securely hold the tyre 6 in position in the recess in the felloe. The
screwed pins c are formed with square necks just below their heads to fit square
holes in the strip c, by which means, the screwed pins are prevented from rotating
in the said strip c.
According to the modification represented at Figure 4, we place a plain metal strip
or sections c in the recess or space 6 in the tyre, and we drill holes through the felloe
from the inner periphery thereof into the metal strip or sections c, which latter we
form with tapped holes to receive screws c¹* passed into the same through the holes
in the felloe.
By the method of construction herein shown and described, we are enabled to
employ a rubber tyre, either complete in one piece or formed in sections and securely
to fasten the same to the felloe. If desired, instead of employing a solid D shaped
felloe, the same may be made hollow, as referred to in our Provisional Specification.

page_text: We are aware that it has been proposed to use in elastic tyres a continuous band
or strips of metal embedded therein during the process of manufacture and that
such a construction of tyre forms no part of our invention.
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. In wheels for vehicles, the combination with a D or trough shaped metal felloe,
of a rubber tyre formed with a space or recess to receive a metal strip or sections,
which are fastened securely to the felloe by means of screws passing through holes in
the latter, substantially as herein shown and described.
2. In wheels for vehicles, the combination with a D or trough shaped metal felloe,
of a rubber tyre, a dovetailed or T shaped recess in such tyre, a metal strip or sections
placed in said space or recess, and screws by which the tyre is securely held in
position in the felloe, substantially as herein shown and described.
