PROVISIONAL SPECIFICATION.
Improvements in and connected with Tyres for Cycles and
other Vehicles.
I, JOSEPH TAYLOR, of 101 St. Vincent Street, Glasgow, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to tyres for cycles and other vehicles and it has for its
object to improve their construction.
In carrying out my present invention which is a further development of my prior
invention No. 10,334 of 1893. I so mould or make the rubber tyre that the tread
is supported or suspended on spring supports.
Under one arrangement the tyre is preferably moulded of thick rubber and is
formed with a flat or round tread which is either hollow or solid. The body of the
tyre, in section, is of O shape and the tread is supported on the jaws or edges of
the body and bridges over the gap or space between them. The tyre is, preferably,
moulded all in one piece.
If desired the body may be made 1", 1", 2" or 21" in breadth and the tread
only "," or 1" according as it is desired to give greater or less rigidity to the
tyre. If the body is made broad in proportion to the tread then the spring action
is not so strong and the tyre is softer and more liable to yield readily with a heavy
pressure, but, if the body is comparatively narrow, the tyre is very strong atid will
not yield so readily. In some cases, I prefer, with broad bodied tyres, to inflate or
partially inflate them with air. It is to be understood that I do not confine
myself to the sizes above given as the body and tread may be made any suitable
breadth.
The rim of the wheel should be so made as to support the sides of the body and
thereby strengthen the action of the spring parts of said body.
The body may be made of any desired conformation so as to suit different rims
but I prefer to make it rounded so as to fit into a hollow rim like the "Seddon"
"Dunlop" or "Clincher." The tyre is or may be cemented or otherwise secured
in place.
Under another arrangement the tyre may be formed from a strip of rubber which
is moulded with a flat or round tread in the centre and with curved sides made,
preferably, of O-G shape in section. In this case the tyre is formed by merely
compressing the sides together and inserting the doubled up or bent strip into a
hollow rim. The rim would be of such conformation as to grip and hold the tyre
tightly in place.
The tyres are suitable for cycles, cabs, and other vehicles.
As the rubber of the tyre is thick there is very little danger of puncture in the
case of the inflated arrangement, and with the others it is immaterial whether they
are punctured or not as the spring formation of the tyre is sufficient to give it the
necessary resiliency.
The tyre may be covered if necessary.
In some cases I may use the usual inflated tube and cover it with a cover forined
with a hollow raised tread in the same manner as with the tyre hereinbefore
described. When the tube is inflated it shapes itself to the form of the cover and
thereby supports the tread. The cover may be secured to the rim by means of
wires or in other well-known manner.

page_text: For narrow rims the tyre may be compressed until the body assumes, in section,
an oval or egg shape, with the tread on the top. If desired the tyre may be
moulded into this shape.

COMPLETE SPECIFICATION.
Improvements in and connected with Tyres for Cycles and
other Vehicles.
I, JOSEPH TAYLOR of 101 St. Vincent Street, Glasgow, 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 relates to tyres for cycles and other vehicles and it has for its
object to improve their construction.
In carrying out my present invention which is a further development of my prior
invention No. 10,334 of 1893. I so mould or make the rubber tyre that the tread
is supported or suspended on spring supports.
The tyre is formed of a thick rubber tread, either solid or hollow, which is
supported on the jaws or end parts of a O shaped or somewhat shaped body
and bridges over the gap or space between said parts. The bent sides of the body
form spring supports for the tread.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Figs. 1 to 4 show, in section, different forms of the tyre suitable for cabs, or
carriages.
Figs. 5 and 6 show, in section, forms of the tyre suitable for cycles and other
light vehicles.
Figs. 7 to 10 show, in section, heavier constructions of the tyre suitable for
omnibuses and other heavy vehicles.
Figs. 11 and 12 show, in section, and Fig. 13 in inverted plan an armoured cover
which may be used with the tyre.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same or similar parts.
נן
The tyre illustrated at Fig. 1 consists of a solid rubber tread a which is either
moulded in one piece with or is joined to a rubber body b. This body b, as shown,
is of shape and its upper parts or jaws support the tread. The body may be
made throughout of the same thickness or it may be thickened at the parts ², as
shown, so as to give additional strength and support to the tread.
c is an air space of semi-circular shape which is inflated through a valve d
indicated in dotted lines.
As will be seen the body of the tyre is enclosed in a channel rim e the sides of
which are curved or bent inwards so as to support the sides of the body and at the
same time retain the tyre in place.
fis the wood felloe of a cab or carriage wheel.
If desired the tyre may be made in two separate pieces a, b, the body part
being first made in the flat and thereafter bent to the O shape so that the lines of
its curvature will appear as shown on the drawing. After the body has been bent
to the proper shape the tread a is joined to its end parts b', .
Fig. 2 shows a slightly different form of the tyre which is preferably moulded
in one piece and has an enlarged air chamber c for pneumatic action. As will be
seen the body is in this case made somewhat flatter and lower than the body

page_text: Fig. 1 and the sides of the rim e are also reduced in height thereby saving
weight.
Fig. 3 shows another form of the tyre wherein the shaped body is made
with an extended base so as to fit into the rim e. As will be seen the body is
thickened at the sides 62 and reduced in thickness at the bottom 63. The rim e
is bent inwards so as to grip the side walls of the body and retain the tyre firmly
and securely in position.
In
Fig. 4 shows a tyre of much the same form as that illustrated at Fig. 3.
this case, however, the air chamber is made longer and narrower and an inner
inflatable tube g is inserted in its interior. The parts of the tyre are also made
thicker in proportion to the parts b².
Figs. 5 and 6 show tyres suitable for cycles and other light vehicles. In this
case the rim e is made of light thin metal and is of a V or nearly V shape with
bent over edges e'. The body of the tyre is thickened at so as to increase the
spring and supporting action at these parts and to thereby prevent a complete
collapse of the tyre in the event of puncture. The tyre is thinned at the lower
side 6. This form of tyre provides a large air chamber c so as to give great
resiliency. The walls of the tyre are made, in this case, much thinner than in the
previous forms in order to reduce the weight as much as possible. Fig. 5 differs
inserted in the air chamber c.
from Fig. 6 in having an inflatable pneumatic tube
In Fig. 6 the chamber is itself inflated.
The bus tyre shown at Fig. 7 differs from that at Fig. 4 in that it is of a
heavier construction and has a Ŏ shaped inflatable air tube g' instead of a round one.
The bus tyre Fig. 8 is, as shown, of a slightly different form from that illustrated
at Fig. 7; the sides of its body b are also bulged at in order to catch in the bent
over edges of the rim e. The air chamber is, in this case, of a D shape and is
without an inner air tube. When the tyre is inflated the parts 6° are pressed
tightly into the recesses e¹ on the inside of the rim.
The cover
When the
The bus tyre shown at Fig. 9 is similar to that shown at Figs. 1 and 2 but in
this case the tyre is provided with a cover i. This cover, which has a thickened
tread, is lined on the inside with canvass or like suitable material .
is secured by means of bolts j or screws and metal strips or rings k.
bolts are tightened up the rings k grip and hold the edges of the cover tight
against the wheel felloe f.
The
The bus tyre shown at Fig. 10 differs from the one shown at Fig. 9 in that
the body b is moulded to the same shape as the interior of the metal rim e.
cover, in this case, has longitudinal ribs or pieces of hardened rubber l. These
ribs are, preferably, partially embedded in the softer rubber of the cover and form
a hard running surface or tread. In this case the rings k are secured by screws 1
to the metal rim e.
Figs. 11, 12 and 13 show an armoured cover. The armour consists of metal
plates m having spikes m¹ at their underside. These spikes are inserted in the
inaterial, preferably canvass and rubber, constituting the cover, as shown at
Fig. 12 and are then clinched or bent over as shown at Figs. 11 and 13. If
desired the spikes, instead of being bent over, may be hammered down so as to
rivet the plates to the cover.
The air tubes at Figs. 4, 5 and 7 are shown as partially inflated.
With my improved tyre for vehicles, the load is supported by the joint spring
action of the parts or jaws 6, of the shaped body and the pneumatic cushion
in the chamber c. The parts are made sufficiently strong and resilient to carry
the load and prevent running on the rim. even though the air chamber c be
punctured.
The tread a may be flat instead of round.
In the case of tyres having air tubes within them the outer tyre can be joined
together at any suitable part in its length by means of a dovetail or equivalent

page_text: 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
consider novel and desire to claim'is :-
1. A tyre for vehicles consisting of a tread which is supported. on the jaws or
upper parts of a shaped, or somewhat shaped rubber body and bridges
over the gap or space between said jaws or upper parts, substantially as herein-
before described with reference to the drawings annexed.
2. The several forms and. constructions of tyre for vehicles substantially as
hereinbefore described. and shown on the drawings: annexed.
