PROVISIONAL SPECIFICATION.
Improvements in and relating to Elastic Tyres for the Wheels of
Cycles, Motor-cars, and other Vehicles.
We, EDWARD HENRY TAYLOR, of 35, Lower Gardiner Street, and MICHAEL
DUNNE, of 6, Queens Square, both in Dublin, Ireland, Mineral Water Manu-
facturer, and Hackney Carriage Proprietor, respectively, do hereby declare the
nature of this invention to be as follows:
Our invention relates to resilient solid or cushion tyres for the wheels of
cycles, motor-cars, and other road vehicles, the rims or felloes of which are of
concave formation upon their outer surfaces, the salient feature of our said
invention consisting of an improved means whereby such tyres may be fixed in
position upon the rims or felloes of such wheels without the aid of cement in any
form, the object of our said invention being to provide a tyre having all the
resiliency of a pneumatic tyre without the accompanying hazard of rupture
through punctures and otherwise.
In carrying our invention into effect we provide of rubber, rubber-composition
or other resilient material a tyre of any desired formation in cross section, according
to the particular cross sectional formation of the outer surface of the rim or
felloes of the wheel upon which it is to be mounted, the said tyre having an
internal longitudinal passage formed therein for the reception of a steel or other
metallic or other rod, wire or cord.
For the purposes of our invention the said tyre would be arranged slightly
less in length than the circumferential measurement of the said rim or felloes,
so that a suitable space exists between the meeting ends of the said tyre, the said
rod, wire or the like extending for a suitable distance beyond each end of the
tyre, such extending portions having right and left handed threads formed thereon
for the reception of a right and left hand threaded collar or socket, which by being
screwed thereon, tightens the said rod or the like and so binds the said tyre firmly
upon the wheel, the existing space between the ends of the tyre after such
fixation being filled up by a section of the said tyre arranged to pass over the said
collar or socket and be connected to each end of the tyre by any convenient means.
We may provide means other than the said collar or socket for connecting the
ends of the said wire or rod, and we prefer, but do not confine ourselves to provide
a tyre of such formation in cross section that a longitudinal space or spaces exists
between the said tyre and the rim or felloes of the wheel to enhance the resilient
properties of the former.

Cycles, Motor-cars, and other Vehicles.
We, EDWARD HENRY TAYLOR, of 35, Lower Gardiner Street, and MICHAEL
DUNNE, of 6, Queens Square, both in Dublin, Ireland, Mineral Water Manu-
facturer, and Hackney Carriage Proprietor, respectively, 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:
Our invention relates to resilient solid or cushion tyres for the wheels of
cycles, motor-cars, and other road vehicles, the rims or felloes of which are of
concave formation upon their outer surfaces, the salient features of our said
invention consisting of our improved means, whereby such tyres may be fixed in
position upon the rims or felloes of such wheels without the aid of cement in any
form, the object of our said invention being to provide a tyre having all the
resiliency of a pneumatic tyre without the accompanying hazard of rupture
through punctures and otherwise.
In order that our said invention and the various methods employed by us of
carrying the same into effect may be fully understood, we have hereunto appended
two sheets of drawings of which.
Fig. 1 Sheet 1 is an elevational view of the primary and final ends of a tyre
and the manner of connecting the same together according to our invention.
Fig. 2 is a like view shewing the said ends when brought together as near as
allowed by the intervening universal collar, and also shewing the section or filling
intended to occupy the space between the said primary and final ends.
Figs. 3, and 5 are sectional views of some of the many cross sectional
formations our said clastic tyre may assume.
Fig. 6 is a cross sectional view of the said section or filling shewn detached in
Fig. 2.
Fig. 7 is a section of a spider wheel rim with our elastic tyre in position thereon,
an arrangement more especially applicable in connection with cycles and motor
cars.
Figs. 8 and 9 Sheet 2 are views similar to Figs. 1 and 2, but illustrating an
alternative method of connecting the ends of the binding rod, and its adaptability
for use upon the ordinary felloed wheels of road vehicles.
Fig. 10 is an enlarged plan view of the coupling collar bolt, with the two ends
of the binding rod in position therein, while Fig. 11 is an enlarged cross section
upon the line A B Fig. 9, when the said section or filling is in position thereon.
In carrying our invention into effect we provide of rubber, rubber-composition,
or other resilient material an elastic tyre A, any desired shape or configuration
in cross section according to its intended use, and the particular cross sectional
formation of the outer surface of the rim or felloes of the wheel upon which it
is to be mounted, and in Figs. 3, 4 and 5 we illustrate, merely as examples, some
of the many forms the said tyres may take in cross section to adapt them for the
purposes of our invention.
In the illustrations given in Sheet 1 it is assumed that our improved tyre is
employed upon spider wheels, the rims of which are concave upon their outer
surface such a rim being shewn by B in Fig. 7.
For the purposes of our invention we form in the tyre A, and for the whole of its
length, a longitudinal passage C, this being for the reception of a steel or other
metallic rod, wire, or cord D, the ends of which are provided with right and left
hand male threads a respectively, the length of the tyre A being slightly less

page_text: than the said rod or the like D, and of the circumferential measurement of the
rim B, so that when the tyre is placed around the wheel a space exists between the
primary and final ends of A, while the threaded ends a of D extend beyond the
said primary and final ends of A and receive a collar or socket E, as shewn in
Fig. 1, the said collar or socket being provided with a right and left handed
female thread adapted to engage with the threaded ends a of D, so that the said
collar or socket when rotated by a suitable tool would draw the ends of the rod D
closer together, as shewn in Fig. 2, and so bind the tyre A firmly down upon the
rim B, and in order that the impact between the ends of the said collar and the
ends of the tyre may not cause rupture of the latter through friction, we provide
upon each end of A, and connected thereto by pins or other suitable means, a
metallic or other washer F, surrounding the ends of the apertures C.
In order to augment the elasticity of the tyre A and render it as nearly as
resilient as a pneumatic tyre, we may, under certain conditions of use, provide in
the said tyre, between the aperture C and its tread, an endless or any number of
short passages, cavities, or recesses G, which may be of any desired shape or size
transversally, and at any desired distance from the passage C, as exampled at
Fig. 5, or in communication therewith as at Fig. 4, and we prefer to arrange that
the under surface 6 of the tyre A shall be slightly wider than that of the rim B,
as shewn in Figs. 3, 4 and 5, so that the said tyre needs a slight compression
laterally to place it upon the rim, such compression having the effect of causing
the portion to become concave, so that a space c exists between 6 and B as
shewn in Fig. 7, which further adds to the resiliency of the wheel.
The space left between the primary and final ends of A, when the collar E is
home as at Fig. 2, we cause to be occupied by a filling H (Figs. 2 and 6) which
may be solid, or provided with a passage or cavities G to match its own particular
tyre, the cross sectional formation of which said filling would be the same as that
of A, while its ends d d would be sloped to correspond with, and be keyed to,
the correspondingly sloped primary and final ends of A when pushed between
them and solutioned or otherwise connected thereto, a space J being formed in
the under surface of H capable of being passed over the collar E, the width of its
lower but broken surface e being equal to that of 6 of A and subject to lateral
compression by the rim B in like manner to A when so arranged thus causing
the two portions of its said lower end to more closely approach the collar E.
In Figs. 8 and 9 we illustrate an alternative method of connecting the ends a of
the rod wire or the like D, and which more readily serves for adapting our
improved tyre to wheels, the rims of which are composed of wooden felloes. For
the purposes of adapting our invention to such wheels we provide upon the outer
periphery of the felloed rim K, a concave metallic tyre L, shrunk upon K and
fixed in position by through bolts in the usual way, and within the said tyre L
would be placed the resilient tyre A, the cross sectional formation of A being
regulated by the cross sectional formation of L, both being preferably that shewn
by Fig. 11. In this arrangement we dispense with the collar E and provide in
lieu thereof a bolt N, adapted to pass through one of the bolt holes in the felloes K
previously mentioned, and be therein retained by a threaded nut P as shewn in
Figs. 8 and 11, or by burring over its end in the usual way of such felloe bolts.
The upper end of the bolt N is arranged to form a collar or shoulder R in which
is provided two parallel and adjacent holes through which are passed the two
ends a a of the rod D as at Fig. 10 when arranging the tyre A upon the rim L,
as at Fig. 8, so that when the two ends a a of D are drawn through the collar or
shoulder R by the means of nuts S as at Fig. 10, the primary or final ends of A would
be drawn towards each other as previously described and illustrated by Fig. 9, the
space between the ends of A being filled in by the section or filling H arranged
to cover the ends a a of D and the collar or shoulder R as previously described
and as shewn by Fig. 11.
Although we have herein stated that the arrangement of our invention
illustrated by Sheet 1 renders it adaptable for use upon cycle or like wheels, and

page_text: that the arrangement illustrated by Sheet 2, renders our invention more adaptable
for wheels having a felloed rim it is obvious, and we wish it understood that we
may arrange, that either method of construction is adaptable for either form of
wheel without altering the principle of the method of fixation in either case.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
1st. The fixation of elastic tyres upon wheel rims by the means of a rod, wire, or
cord passing through a longitudinal passage formed in the said tyre, and having
its ends connected and drawn towards each other by the means of a right and left
hand threaded collar or socket substantially as herein described and shewn.
2nd. The fixation of elastic tyres upon wheel rims by the means of a rod, cord
or wire passing through a longitudinal passage formed in the said tyre, the ends
of the said rod or the like being passed through holes in the specially formed
head of a threaded bolt engaging with the rim of the wheel, and being connected
and drawn towards each other by the means of a nut screwed upon each substan-
tially as herein described and shewn.
3rd. In an improved method of fixing elastic tyres upon the concave rims of
vehicle wheels, the combination of such an elastic tyre A, with or without a passage
or passages, recesses or cavities such as G and having a through passage such as
C. the said tyre being fixed in position upon a wheel rim such as B by the means
of a rod, wire, or cord such as 1), passing through the said passage C, and having
its threaded ends a a, connected and drawn towards each other for tightening and
fixing A upon B, by the means of a two way threaded collar or socket E, the space
between the ends or the said tyre being filled by a cemented section piece such as
1, substantially as herein set forth and shewn by the appended drawings.
4th. In an improved method of fixing elastic tyres upon the concave rims of
vehicle wheels, the combination of such an elastic tyre A, with or without a
passage, recesses, or cavities, such as G, and having a through passage C, the said
elastic tyre being fixed in position upon a metallic tyre such as L, mounted upon
a felloed wheel rim such as K, by the means of a rod, wire, or cord such as D,
passing through the passage C, and having its threaded ends a a, passed through
the head R of a bolt N, engaging with the felloes K, the said ends a a being drawn
towards each other for tightening and fixing A by the means of nuts S screwed
thereon, substantially as herein described and shewn by the appended drawings.
