PROVISIONAL SPECIFICATION.
An Improvement in Iron or Steel Tyres of Carriage Wheels of
every description.
JOHN COLE, 22, Avenue Terrace, Turnham Green, London, W., Carriage
Builder, do hereby declare the nature of this invention to be as follows:-
An improvement in iron or steel tyres of carriage wheels of every description.
The novelty of this invention consists in the shape or pattern of the tyre, the
object of which is to prevent the wheels of carriages from skidding or sliding
upon or against tram lines or metals while the carriage is passing over them,
and to protect the felloes or rim of the wheel from the kerb of the pavement.
This tyre is made with projections on the sides to grip the tram lines and called
a lever to lift the vehicle, and pass it over in safety.
1st. These projections are 2 or 3 inches long (more or less) and about the same
thickness of the tyre standing out about an inch and comes up to a point or
almost so
in order to get a firm hold of the tram line. So that instead
of the front of the tyre being smooth, and straight, that goes next to the tram-
line, (when the road is worn down) these projections, all round the wheel back,
& front, being rough will not allow the wheel to slip
.or skid.
2nd. The steel or iron tyres that will be used as channels for india rubber are
made or so constructed that when the weight of the vehicle & passengers are
upon it, the projecting parts of the tyre will take the bearing when running in
the metals instead of the rubber being squeezed into the hollow of the tram line
or into the different points or junctions of the metals, & will prevent the rubber
from being pulled out, or cut by the sharp edges of the tram lines.

I, JOHN COLE, 22, Avenue Terrace, Turnham Green, London, W., Carriage
Builder, 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:-
An improvement in iron or steel tyres of carriage wheels of every description.
The novelty of this invention consists in the shape or pattern of the tyre, the
object of which is to prevent the wheels of carriages from skidding or sliding
upon or against tram lines or metals while the carriage is passing over them

page_text: and to protect the felloe or rim of the wheel from the kerb of the pavement.
This tyre is made with projections on the sides to bear upon the tram lines and
called a lever to lift the vehicle and pass it over in safety."
These projections are two or three inches long (more or less) and about the
thickness of the tyre standing out about half an inch and comes up to a point, or
almost so, in order to get a firm bearing upon the tram line. So that instead
of the front of the tyre being smooth and straight that goes next to the tram-
line (when the road is worn down) these projections all round the wheel back
and front, being rouwill not allow the wheel to slip or skid.
The steel or iron tyres that will be used as channels for india rubber are
made or so constructed that when the weight of the vehicle and passengers are
upon it the projecting part of the tyre will take the bearing when running in the
metals, instead of the rubber being squeezed into the hollow of the tram line or
into the different points or junctions of the metals and will prevent the rubber
from being pulled out or cut by the sharp edges of the tram line.
For purposes of illustration I will now refer to the annexed drawings, in
which:
Figure 1 is a plan view shewing my construction of tyre.
Figure 2 perspective view of tyre constructed according to my invention in
position upon a wheel.
Figure 3 cross section of modified form of tyre.
Referring to Figures 1 and 2, the tyre a which may be of iron or steel is provided
with projections b. These projections may be caused in any convenient manner
upon the tyre. The action of these projections is as follows. In the event of the
wheel running into the tramlines the tyre is prevented from sinking therein, and
when the vehicle is turned so as to remove the wheels from the tramlines the pro-
jections will engage upon the edges of the tramlines, and lift or lever the tyre
from same. The same will apply to roads in which rough stones are employed,
as this lifting or levering action will take place and so protect the felloe or rim
of the wheel, this protection being particularly noticeable when a wheel is being
driven up to the kerb.
Referring to Figure 3, in this case the tyre is provided with the projections b
upon each side. These projections are of such a shape and size that in the event
of the tyre dropping into a tramline the projections & will engage upon the tramline
or metal and prevent the rubber c from being squeezed and when it is required to
turn off the tramlines this can be easily done owing to the supporting or lifting
action of the projections. By this arrangement the rubber tyre is protected from
injury, and also the ease with which the vehicle may be turned is increased,
and skidding to a great extent prevented.
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. The tyre for wheels substantially as described and illustrated herein and
for the purpose set forth.
2. In tyres for wheels: the employment of projections formed upon the tyre
substantially as described and illustrated herein and for the purpose set forth.
3. In tyres having a channel for carrying the rubber bearing surface: the
employment of projections upon the sides of said tyre substantially as described
and illustrated herein and for the purpose set forth.
