Improvements in and relating to Elastic Tyres.
1, JOHN LIDDLE, of 154, St. Vincent Street, in the County of the City of Glasgow,
North Britain, Patent Agent, do hereby declare the nature of this Invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement: -
The object of this Invention is to provide a tubular tyre which is noiseless and
elastic, cheap and durable, easily constructed and light as to weight, which will
avoid the inconveniences attending puncture, incident to the present pneumatic
tyres, reference being had to the accompanying drawings in which;
Figure 1 is a broken elevation of a tyre with a portion of the rim.
Figure 2 is an enlarged transverse section, taken on line 2 Figure 1
Figure 3 is a broken sectional elevation taken on line 3 Figure 2.
Figure 4 is a perspective view, showing the manner of fastening the ends of the
strips.
A is the outer rubber tyre or casing.
B is the rim of the wheel.
C is a felt cushion under covering.
Dis the canvas enclosing the core.
E is a longitudinal layer of thin wood slats.
e is the open space between the slats or strips of wood.
Fis a felt or wood cushion in spaces between the slats.
G is a metal ferrule for fastening the ends of the slats or strips of wood.
Similar letters refer to similar parts throughout the drawings.
In the construction of this improved tyre, I use either the ordinary rubber outer
casing A or a similar casing of other material as canvas with an outer covering of
rubber or paint or I may use a casing in which the part next to the rim or felly of
the wheel is flat should I prefer it. Instead of the inner tube or core of inflated
rubber as now used in the construction of the present pneumatic tyre, I construct
a tube composed of long thin slats or strips of wood E of the width of an ordinary
tyre, and about one sixteenth of an inch in thickness, and wind it on the circum-
ference of the rim B of the wheel loosely, five, six, or more times as may be required
for the purpose until the proper space or thickness of the tyre is obtained as in
When the slats or strips are

so wound or arranged the ends are secured by means of the metal ferrule G. As
the slats or strips are not wound tightly I place between the interstices e, at intervals
cushions or strips of felt or wood F. Having thus arranged the slats or strips of
woou in proper shape for the tyre and secured compactly, the outer edges of the
wooden strips are then rounded so as to partake a tubular form to be readily in-
serted into the outer casing, as shown in Figure 1. I then take a narrow strip of
canvas and wind it around the tube or core of wood and felt and completely enclose
it, making it compact yet elastic; as shown by D Figure 3. The tube or core thus

tween the outer covering A and the inner tube as above constructed I place another
strip of felt C to serve as a cushion between the inner tube or core and the outer
casing A. In the construction of the wheel the tubular tyre is then secured to the
rim B by means of screws b at intervals, or if I prefer I may secure the tyre by
means of transverse bolts with washers thereon embracing tyre and rim to prevent
displacement of the tyre sidewise or by means of a clasp as may best suit my pur-
pose. The tyre thus constructed is elastic, light and durable and requires no
inflation.
Having now particularly described-and- ascertained the nature of my Invention
and in what manner the same is to be performed, I declare that what I claim is:
1. In the construction of an elastic tubular tyre the combination of an outer
covering of rubber or canvas having a coating of rubber or paint an inner cushion
of felt an inner tube or core, composed alternately of thin wooden slats or strips
and short strips of felt or wood and firmly enclosed in canvas, as and for the purpose
above described.
2. In the construction of an elastic tubular tyre, the combination of an inner
tube, composed of one or more ribbons of tough elastic wood wound on the circum-
ference of the rim with cushions of felt or wood and wrapped with canvas as and
for the purpose above described.
3. In the construction of an elastic tubular tyre an inner cushion of felt, an
inner tube or core composed of thin strips of elastic wood separated at intervals by
cushions of felt and enclosed in canvas, the whole being secured to the rim by
screws, or by bolts fitted in the rim transversely with washers embracing the rim
and tyre, or by a clasp as and-for the purpose above described.
4. In the construction of an elastic tubular tyre an inner tube or core composed
of thin strips or ribbons of wood, the ends secured by a metal ferrule, the inter-
stices cushioned with strips of felt or wood; said tube or core wrapped in canvas,
with a felt cushion between the tube or core and outer casing as and for the purpose
specified.
'
5. The combination of a rim having a flat tread a tyre with a flat web which fits
squarely on the flat tread, the bolts which pass transversely through the rim and
washers on the ends of the bolts and embracing the tyre and rim closely to hold the
tyre against sidewise displacement on the rim as and for the purpose described.
