PROVISIONAL OF MOIFICATION
A New and Improved Wheel Tyre for Road Vehicles
I, AUSTIN STRANGE, Wheelwright Ponnsylvania Wheel Works, Cold Ashton,
near Chippenham, in the County of Gloucester, do hereby declare the nature of this
invention to be as follows.—
My invention relates to an unprovement in wheel tyres for road vehicles, and
more particularly in the dispensing with nailing and similar methods commonly
adopted after the tyre has been expanded and shiunk on to the wooden felloes.
The invention consists of the use of recesses in the inner face of the iron or
steel tyre, of any convenient shape or dimensions, and spaced at any suitable
distance apart in a straight line, or "zig-zag," as may be desired.
Another feature in iny improved tyle is the special form of section, which

15 of the same outline as the two bonds before mentioned when they are in position
upon the wheel. the narrower one of the two being at a small angle ieferied to the
large one. That is to say; the section of my new tyre is such, that the innei
edge, referred to the wheel when on the vehicle, is slightly bevelled toward the
centre of the tyre circle.
The manner in which the before mentioned recesses come into position is as
follows.

When the tyre has been heated and placed over the felloe, the contraction in
cooling compresses the wood to such extent, that portions of the felloe surface are
forced into the shallow recesses; this holds the tyre in position, and is an efficient
aubstitute for nails or bolts. The object of that portion of the tyre which is
bevelled, or at an angle with the other pait is; that when the wheel is on hard
ground, one portion only of the tyre is in contact; and when the wheel is on soft
ground, the full width including the bevelled portion comes into operation to prevent
Sinking of the wheel

1 AUSTIN STRANGE of Pennsylvania Wheel Works Cold Ashton near
Chippenham in the County of Gloucester, Wheelwright, 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 :-
My invention as herein descubed is an improved wheel tyle for road vehicles,
and is specially arranged in such manner as to dispense with nails, spikes, screws
and the like, for fastening the tyre to the wooden felloes of the wheel. My new
tye is formed of non or steel bats rolled to a special cicss section, and the said

travelling on hand and soft ground it is usual to fix upon the wheels a secondary
tyre beside the normal tyre and bevelled at various angles upon the wooden felloe

page_text: in such a manner that, when traversing hard ground, the normal tyre alone is 10
contact with the ground, but upon entering on and traversing soft ground the
bes elled tyre comes into use as an auxiliary; and the two tyres together present a
broad surface and thus prevent the wheel sinking into the soft ground.
In my invention the before mentioned combination of flat and bevelled tyres ale
formed in one bar of special and suitable cross section, and for the purpose before
named.
My improved tyre is fitted to the wooden felloes of road vehicles without nails,
screws, or spikes, and in the following manner
Upon the inner surface of the bar from which the tyres are made, shallow
recesses are formed of any desired outline, and spaced at suitable intervals along
the bar as hereinafter shewn; or in any other suitable manner as may be desued.
The tyre is made in the usual manner from the bar, and is expanded by heating
before being placed upon the wooden felloes.
The contraction of the tyre in cooling compresses the wood of the felloes
sufficiently to form plugs or projections upon the circumference, and, compressed
within the shallow recesses before mentioned; and prevents the slipping of the tyre
from the wooden felloc.
Having reference to the accompanying drawings,
Figure 1. 1opresents the cross section of a bar from which the improved tyle 15
made, and shews the auxiliary bevelled portion at A. The normal ty re face at B aud
the shallow recesses at C. C.-D represents the wooden felloe upon which the plugs
or projections are formed by the compression of the tyre in cooling. The plugs or
projections are shewn at d d.
Figure 2. represents a portion of the special bar from which the tyres are made,
and indicates that face of the bar which comes into contact with the wooden felloe,
the shallow recesses are shewn at C. and the bevelled part at A.
Figure 3. shews the new tyre in position on a wheel, the bevelled portion being
nearest the vehicle as at A.
Sumila lotters of reference indicate the same parts in all the figure.
It is intended to make these improved tyres from special steel and iron bars of
various weights and strengths, and to fit them upon any class of road vehicle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 do declare that what I
claim is
1. A combination in one bar of iron or steel of special section, of two tyres as
described nud for the pun pose named, that is to say -One part of the new tyre
section is used in traversing hard ground, and both parts of the said tyre come into
use when traversing soft ground substantially as described
2. The combination described and a series of recesses formed upon the inner
surface of the tyre or upon that face of the bar which comes into contact with the
wooden telloe
3 The combination described and the recesses as described to receive wooden
plugs on excressences formed on the surface of the wooden fellnes by the contraction
upon the said felloes of the iron or steel tyres as herembefore described.
4. I especially claim for the compressed projectious and shallow slots as described
for holding any kind of tyle for road vehicles.
