AN IMPROVED OF WHEELS, CHIEFLY APPLICABLE TO VELOCIPEDES
Year: 1884

page_text: I'NAHUM SALAMON of 27 Holborn Viaduct in the City of London, Velocipede
Manufacturer, do hereby declare the nature of my invention for "AN IMPROVED
OF WHEELS, CHIEFLY APPLICABLE TO VELOCIPEDES," to be as
_MANUFACTURE
follows:-
+
The object of this invention is to produce in an economical manner a strong
and light wheel suitable for Velocipedes.
To this end I use for the felloe a weldless steel tube circular in cross section, and
instead of compressing it, as under my Patent of October 3rd 1877 N° 3689 to
form a bed for the elastic tyre, I retain the circular cross section of the felloo,
and surround the felloe with a tyre of vulcanized india-rubber of peculiar
shape.
I am aware that it has already been proposed to apply vulcanized india rubber
to wheels having a tubular felloe, but in such case the india rubber compound was
applied in a green or soft state and formed an envelope to the felloe. This mode
of applying the india-rubber compound necessitated the subjecting of the covered
wheel to the curing process, and thus rendered the use of the invention, through
the attendant expenses, impracticable.
My tyre I form of a suitable section, moulding it so as to embrace somewhat.
more than half the diameter of the tubular felloe, and the inner face of this tyre
I make either smooth or with fine ribs, as may be found most convenient.
The moulded material I submit to the curing process, and I am thus enabled, at
comparatively little cost, to produce tyres ready for use by the Velocipede
Manufacturer.
In applying the tyre to the tubular felloe, the inner surface of the tyre is
coated with suitable cement, and the tyre is sprung into its place on the felloe.
The tension of the cured rubber will produce a close contact of the parts, but to
ensure a firm adhesion of the india rubber compound to the tubular metal I apply
thereto a circular contracting clamp and thereby obtain equal pressure on the whole
periphery of the tyre, maintaining that pressure until the cement has hardened and
the junction of the parts is secured. The hub and spokes of the wheel I propose
to connect with the felloe in any well known or approved manner before the
application of the tyre thereto.

page_text: I NAHUM SALAMON of 27 Holborn Viaduct, in the City of London, Velocipedo
Manufacturer 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 this invention is to produce in an economical manner a strong and
light wheel suitable for Velocipedes.
To this end I use for the felloe a weldless steel tube circular in cross section,
and instead of compressing it, as under my Patent of October 3rd 1877 N° 3689,
to form a bed for the reception of the elastic tyre, I retain the circular cross section
of the felloe, and surround the fellce with a tyre of vulcanized india rubber of
peculiar shape.
I am aware that it has already been proposed to apply vulcanized india rubber
to wheels having a tubular felloe, but in such case the india-rubber compound was
applied in a green or soft state, and formed a complete envelope to the felloe.-
This mode of applying the india rubber compound necessitated the subjecting of
the covered wheel to the curing process, and thus rendered the use of the invention,
through the attendant expenses, impracticable.
My tyre I mould of such a section as will enable it to embrace some half, or less
or more, of the section of the tubular felloe, and the inner face of this tyre I make
either smooth or with fine ribs, as may be found most convenient.
The moulded material I submit to the curing process, and I am thus enabled,
at comparatively little cost, to produce tyres ready for use by the Velocipede
manufacturer.
In the accompanying Drawing,
Fig. 1 shows in side elevation my improved construction of velocipede wheel;
and
Fig. 2 is a cross section of the same.
The tubular felloe A, it will be seen, is overlaid by the elastic tyre B, which
extends over one half the periphery of the tube.
In applying the tyre to the tubular felloe, the inner surface of the tyre is coated
with suitable cement, and the tyre is sprung into its place on the felloe. The
tension of the cured rubber will produce a close contact of the parts.
In some cases I may find it desirable to omit the use of cement for securing the
tyre in place. This I am enabled to do by providing a compound tyre composed of
Boft and hard rubber, the hollow base being formed of hard rubber, and joined
before curing to a cushion of soft rubber, after the manner described in the
specification of Robert Offord, Patent dated 29th November 1860, No 2932.
This compound tyre I soften by heat to provide for its expansion, and I
apply it in its softened state to the felloe, relying upon the contraction of the
vulcanite base, while cooling, to obtain a firm junction between the tyre and the
felloe.

page_text: If desired, cement may be employed in this case also, the further to ensure a firm
union between the tyre and the felloe.
The hub and spokes of the wheel I propose to connect with the felloe in any
well known or approved manner before the application of the tyre thereto.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The combination with a weldless steel tubular felloe, of an india rubber vul-
canized or cured tyre so formed as to seat itself upon the convex surface of the
felloe, as above described, and retain its place thereon with or without the
assistance of cement.
