Improvements in or relating to Elastic Tyres for Carriage Wheels.
CHARLES CHALLINER, of 15, Plymouth Avenue, Longsight, near Manchester,
in the County of Lancaster, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object a more mechanical method of constructing such
tyres known as flexible steel coil tyres such as described in Willoughby &
Horsfield's Patent, No. 4064, 1890.
I first mount upon the felloe of the wheel a suitable trough shaped section rim
which may be of any convenient section, or the felloe may form the rim, or I may
dispense with the felloe and mount the rim direct upon the spokes of the wheel.
I then place in the trough shaped rim a cushion of india-rubber, or other suitable
elastic substance which will be of a suitable section and may be in one or more
pieces, placed into the rim until filled up. I then make a flexible coil of steel or
other suitable material which will be in segments of any convenient length and
built up and fixed upon the periphery of the elastic cushion until the wheel is
made complete, I then provide a number of suitably formed bolts, screws, or their
equivalent which will be attached to the flexible coil segments. The bolts may
have tee heads or other convenient shape; one part of the head of the bolt or
screw will be attached to one segment of the flexible steel coil whilst the other
part of the head will be attached to the adjoining segment, thus holding the two
ends of each segment whilst the shank of the bolt or screw will pass radially
through holes provided in the elastic cushion through the rim and felloe. The
aforementioned bolt or screw will be provided with a suitably formed nut or screw
bush for the purpose of holding the segment flexible steel coil firmly around the
reriphery of the elastic cushion, or I may reverse the bolt or screw and make a
suitably formed uut or screwed bush, attached to the flexible steel coil whilst the
bolt or screw will pass upwards from the under-side of the felloe or rim and engage
with the nut or screwed bush in the flexible steel coil.
I may, if necessary, have the coil in one continuous piece and attach bolts or
screws at any convenient part of the elastic flexible steel coil or I may also attach
bolts or screws to the segment steel coil at any part or in any numbers, or I may
dispense with the steel coil and use tubes or their equivalent of any length and in
any numbers.
This invention is also applicable to such wheels known as trolley wheels.

I, CHARLES CHALLINER, of 15, Plymouth Avenue Longsight, near Manchester,
in the County of Lancaster, 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:-
This invention has for its object a more mechanical method of constructing such
tyres known as flexible steel coil tyres, such as described in Willoughby and
Horsfield's Patent, No. 4064, 1890.
I first mount upon the felloe of the wheel of a suitably trough shaped section
rim, which may be of any convenient section or the felloe may form the rim, or
I may dispense with the felloe and mount the rim direct upon the spokes of the
wheel.
I then place in the trough shaped rim a cushion of india-rubber or other suitable
elastic substance which will be of a suitable section and may be in one or more
pieces placed into the rim until filled up. I then make a flexible coil of steel or
other suitable material which will be in segments of any convenient length and
built up and fixed upon the periphery of the elastic cushion until the wheel is
made complete, I then provide a number of suitably formed bolts, screws, or their
equivalent, which will be attached to the flexible coil segments, the bolts may have
tee heads or other convenient shape, one part of the head of the bolt or screw
will be attached to one segment of the flexible steel coil, whilst the other part of
the head will be attached to the adjoining segment thus holding the two ends of
each segment whilst the shank of the bolt or screw will pass radially through holes
provided in the elastic cushion through the rim and felloe. The aforementioned
bolt or screw will be provided with a suitably formed nut or screwed bush for the
purpose of holding the segment flexible steel coil firmly round the periphery of
the elastic cushion, or I may reverse the bolt or screw and make a suitably formed
nut or Ecrewed bush attached to the flexible steel coil whilst the bolt or screw will
pass upwards from the underside of the felloe or rim and engage with the nut or
screwed bush on the flexible steel coil. I may if necessary have the coil in one
continuous piece and attach bolts or screws at any convenient part of the elastic
flexible steel coil, or. I may also attach bolts or screws to the segment steel coil at
any part or in any numbers, or I may dispense with the steel coil and use tubes or
their equivalent of any length and in any numbers.
In the accompanying drawings I have shewn how my invention may be
conveniently carried into practice.
Fig. 1. is part side view of wheel and section.
Figure 1. "A"is the felloe of the wheel. "B" is the trough shaped section
rim. "C" cushion of india-rubber or other suitable elastic substance. "E" is a
bolt or screw with a suitably formed head of which one part may be attached to
one segment of D (which is the flexible coil) and the other part of E may be
attached to the adjoining segment D' E' is the bolt shank passing radially through
rim B and felloe A. E is a suitably formed nut or bush which in conjunction
with E and E' is for the purpose of holding the flexible steel coil D firmly round
the periphery of the elastic cushion C.
By my invention it will be readily seen that I get a more mechanical method of
securing flexible steel tyres or their equivalent and in no way interfering with the
tyre as regards its flexibility, and also it can be attached or loosened and removed
from the wheel much more easily and expeditiously than has hitherto before been
possible.

page_text: Having now particularly described and ascertained the nature of my inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1. Securing flexible steel coil tyres or their equivalent to the rims of wheels in
the manner described in combination with a rubber or elastic cushion & a trough
shaped section rim as described in the drawings annexed.
2. The application of the aforesaid tyre to trolley, carriage, or common road
wheels, also motor or other power vehicles.
