Improvements in Flanged Wheels for Railway and Tramway
Locomotives and Vehicles.
1, WILLIAM EDWIN HEYS of 70 Market Street, Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to flanged wheels for railway and tramway locomotives
and vehicles, and consists in improved means for connecting the flanged tyres with
the rims of the wheels.
→
According to this invention, the rim of the wheel is constructed with an internal
flange upon one side, which may or may not be continuous. The tyre is constructed
to fit upon the wheel rim, and is provided, on that side of the tyre which will be.
nearer to the annular flange on the rim, with an internal continuous or discontinuous
flange or projection. When the tyre has been placed upon the rim of the wheel
the tyre flange or projection is clasped or beut over the flange of the rim. In .
ordinary cases both the rim and the tyre flanges would be interrupted at the.
spokes, and the tyre flange, being bent over between the spokes, would thus prevent:
the movement, in the direction of rotation, of either the rim or the tyre relatively
to the other. Since also the tyre flange is bent over the rim flange, movement of
one relatively to the other in the direction of the axis of rotation is prevented.
-That
Other advantages following from the adoption of these improvements are:-
the rim may be about as wide as the tyre, thereby ensuring a better gripping
surface. That no set screws, rings, or other separate parts are required with a
consequent increase of simplicity of construction, and greater immunity from risk.
And, that adhesion tyres cannot possibly slip on the rims of their wheels.

Improvements in Flanged Wheels for Railway and Tramway
Locomotives and Vehicles.
1, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Chartered Patent Agent, 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 :-
This invention relates to flanged wheels for railway, tramway and other like
locomotives and vehicles, and consists in improved means for connecting the flanged
tyres with the rims of the wheels.
According to this invention, the rim of the wheel is constructed with an internal
flange upon one side, which may or may not be continuous. The tyre is constructed
to fit upon the wheel rim, and is provided, on that side of the tyre which will be

page_text: nearer to the annular flange on the rim, with an internal continuous or discontinuous
flange or projecting part. When the tyre has been placed upon the rim, of the
wheel, the tyre flange or projecting part is clasped or bent over the flange of
the rim. In ordinary cases, both the rim and the tyre flanges would be interrupted
at the spokes, and the tyre flange, being bent over between the spokes, would thus
prevent the movement in the direction of rotation, of either the rim or the tyre
relatively to the other. Since also the tyre flange is bent over the rim flange,
movement of one relatively to the other in the direction of the axis of rotation is
prevented.
:-That
Other advantages following from the adoption of these improvements are:-
the rim may be about as wide as the tyre, thus ensuring a better gripping surface.
That no set screws, rings or other separate parts are required, with a consequent
increase in simplicity of construction, and greater immunity from risk. Aud, that
adhesion tyres cannot possibly slip upon the rims of their wheels.
The accompanying drawings illustrate in what manner my said invention,
communicated to me from abroad, may be carried into effect, and will be hereinafter
referred to.
Figure 1 is a sectional view of a wheel rim and tyre constructed and connected
according to these improvements.
Figure 2 represents in side elevation, a part of a wheel and its tyre in process of
structural connection.
Figure 3 and Figure 4 represent sections taken through the tyre alone.
R indicates the wheel rim, S its spokes, H its hub, F the annular flange ou the
rim, T the tyre, and P the flange or projecting part or parts on the tyre, which is
or are turned over so as to grasp the flange F.
As indicated by Figures 1 and 2, the flange F is discontinuous, being interrupted
by each spoke at its junction with the rim. The tyre flange P must therefore be
similarly interrupted by vacancies, as indicated by Figure 2, corresponding with
the spokes. In connecting the tyre with the wheel, the tyre is heated and placed
upon the rim with the projections P opposite the spaces between the spokes. The
projecting parts P are then bent down and clasped over the flange of the rim as
shewn by Figure 1, and the two parts are thereby firmly connected together. The
preliminary heating of the tyre may in some cases be omitted.
Ordinarily, the part P would be produced originally in the tyre as indicated by
Figure 4, by rolling or otherwise, and the parts opposite to the spokes would be cut
out. This method of construction may however be varied, as shewn for example
by Figure 3. In this case the projecting part P is produced much thicker and
shorter, and the part p bounded by the dotted line is machined out. This machined
out recess receives the flange of the rim, over which the point p¹ is bent as shewn
by Figure 1.
Usually it will be found advantageous to make the rim and tyre respectively with
continuous flanges F and P, not interrupted by the spokes, so that the interlocking
also is continuous. This is effected by making the flange F wholly on one side of
the spoke ends, and renders the separation of a part of the tyre owing to a double
fracture, less probable. As an additional precaution to obviate the same result
there may be employed in addition to the means and appliances hereinbefore
described and constituting the essential features of this invention additional means
and appliances of known or suitable character and construction for connecting the
tyre and rim on the side opposite to that on which the flanges F P are arranged.
Such an addition however constitutes no part of this invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A flanged wheel in which the tyre is secured upon the rim without the aid of
screws rings and other separate appliances, constructed substantially as hereinbefore
described with reference to the accompanying drawings.

page_text: 2. The herein before described means for securing flanged tyres upon wheels, and
which consist of a continuous or discontinuous flange upon the wheel rim and a
corresponding flange or projection upon the tyre capable of being bent over the rim
Aange, substantially as set forth and as illustrated by the accompanying drawings.
