Improvements relating to Compound Tyres for Wheels of
Road Vehicles.
I, HENRY SOMERVILLE FEARON, of 6 Great Winchester Street, City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for object certain improvements relating to compound Tyres
for wheels of Road Vehicles.
For the purpose of my invention, I construct Tyres from a combination of gutter
shaped rims with inwardly bent flanges, a rubber cushion, and an outward tread,
both of which are in sections and shaped to fit loosely into the inwardly flanged
gutter shaped rim at a gap provided, and then be pushed round therein, in successive
order and crowded into contact to make the tread sections as nearly in touch with
each other as is possible without destroying the independent compression of each
section of rubber brought to bear under the weight of the load carried by the Vehicle
to which such wheels and compound Tyres are fitted.
If desired, the sections of rubbers and treads can be moulded to each other as
distinct blocks, in which case the moulding of the rubber can be so arranged that it
alone engages under the inwardly formed flanges of the otherwise gutter shaped
rim.
The faces of the treads may be flat or be rounded but are preferably of less width
than that of the rim to protect them from contact with the kerbs of paths when the
Vehicle is drawn up alongside on the road.
The treads can be so shaped that they have a holding on the rubber. even if from
rough usage they separate or disintegrate from each other.

Improvements relating to Compound Tyres for Wheels of
Road Vehicles.
I, HENRY SOMERVILLE FEARON, of 6 Great Winchester Street, City of London,
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 object certain improvements relating to compound Tyres
for wheels of Road Vehicles.
For the purpose of my invention and as I show at Figure 1 of the annexed
Price 8d 1

page_text: drawings, I construct Tyres from a combination of gutter shaped rims A with
inwardly bent flanges B, B, a rubber cushion C and an outward tread D both of
which are in segments and shaped to fit loosely into the inwardly flanged gutter
shaped rim at a gap provided and then be pushed round therein in successive order
and crowded into contact to make the tread sections as nearly in touch with each
other as is possible without destroying the independent compression of each section
of rubber brought to bear under the weight of the load carried by the Vehicle to
which such wheels and compound Tyres are fitted, the gap being afterwards closed up
by a plate E shaped to correspond to the outline or coufiguration of the other parts
and secured to the felloe F by bolts or screws G.
If desired, the sections of rubbers C and treads D can be moulded to each other
as distinct blocks, as in the section Figures 2 3, 4 and 5, in which case the moulding
of the rubber C can be so arranged that it alone engages under the inwardly formed
flanges B, B, of the otherwise gutter shaped rim A.
Figure 2 is a longitudinal section of a square exterior build of Tyre D with inner
lips a, a, for einbracing the rubber C which is moulded in it, the portions b, b, of
which form ledges for the base of the lips a, a, to rest on. Figure 3 is a transverse
section of a rounded faced Tyre segment with the rubber moulded in it, the ends
of said segment having depending prongs d at the ends, as seen at Figures 4 and 5,
(which are end elevations of one of the segments or Tyre blocks) to prevent the
rubber bulging outwardly, one of which shows a hollow in the rubber block to
allow for compression, the latter being solid so that the part next the rim A can be
bulged at the ends and so form a cushion against the next or adjoining segments.
These segment blocks are preferably of less width than that of the rim A to
protect them from contact with the kerbs of paths when the Vehicle is drawn up
alongside on the road.
The treads D are so shaped that they have a holding on the rubber C even if
from rough usage they separate or disintegrate from each other.
Figure 6 represents a part side elevation in which the sections of tread and
rubber are of less length than those shown at Figure 1, the sections being slid or
pushed along after their entry at the gap, as before stated, the gap being then
closed by the plate E and secured by a bolt or screw G.
Figure 7 indicates a section of the rim A where the gap exists, E being the
plate with a curled in lip B to correspond to that of the rim.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improvements in compound Tyres for Road Vehicles, consisting of a
plain inwardly lipped rim A, sectional or segmental rubber blocks C, sectional or
segmental treads D which are built up by sliding them end on into position from
a gap in the rim, this being afterwards closed by a plate E affixed to the felloe F,
as set forth.
2. Constructing Tyres of wheels for Road Vehicles from a combination of
segmental rubber blocks, segmental metal treads D, as separate articles or moulded,
each as single articles and sliding them into position within a doubie lipped rim from
a side gap therein, as described with reference to the annexed drawings.
