Improvements in and relating to Elastic Tyres for Oycles, Carriages,
and like Vehicles.
FRANCIS BEAUCHAMP, Sunny Side, The Green, South Tottenham, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in cycles carriages and like vehicles.
For this purpose I provide a wire spring of two or three coils more or less as may
be required which passes round the periphery of the wheel and is covered or bound
with horsehair or any other fibrous material and enveloped in the ordinary rubber
covering or any other covering for enclosing the spring or hair. The rim of the
wheel has a convenient number of longitudinal apertures or any suitable shape cut
therein for the purpose of ramming the hair or fibrous material round the periphery
of the wheel after the envelope or covering is placed in its proper position. When
the envelope or covering is rammed out to its proper tension the apertures which
are provided with shutters are closed and fastened. As the horsehair is being
rammed through the said apertures it forces the sides of the envelope out into a
convenient fastening for the purpose of holding the envelope or covering secure
thereon.
I sometimes dispense with the spring and ram the envelope with the horsehair
or fibrous material sufficiently tight to give it the proper tension or elasticity. I
fasten the said envelope with pieces of metal or hard substance across the rim to
bear or press against several segments of wire round the inside of the envelope
for the purpose of fixing the same.

Improvements in and relating to Elastic Tyres for Cycles, Carriages
and like Vehicles.
I, FRANCIS BEAUCHAMP, of Sunny Side, The Green, South Tottenham, in the
County of Middlesex, 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 improvements in elastic tyres for cycles, carriages,
and like vehicles, and consists in the employment of horse-hair, or other suitable
fibrous material, within an ordinary cover of indiarubber or other suitable material,

page_text: for the purpose of rendering such cover elastic or resilient when the wheel is in
use.
In order to increase the resiliency of the tyre I sometimes employ springs
of various kinds in combination with the horse-hair or other filling material.
And in order that my invention may be clearly understood I will now proceed
to describe the same in connection with the accompanying sheet of drawings,
in which Figure 1 illustrates the transverse section of a tyre, a being the metal
rim, b the indiarubber or other cover, c the horse-hair or other fibrous filling
material, which is introduced into the interior of the tyre, after the cover b is placed
in position, through suitable openings a formed in the rim a at convenient dis-
tances apart round the circumference, and rammed home by suitably shaped tools
or instruments, which are also introduced through the holes a¹. These holes are
preferably closed by a cover-plated in the manner shewn, d¹ being on internal bar
having a screwed pin in the middle of its length. The hole a¹ is made of
sufficient length in one direction to enable the internal bar d to be inserted, when
it is turned into the position shewn in Figure 1, its ends bearing upon the edges b¹
of the indiarubber or other cover b. The cover-plate is then threaded on to
the screwed pin da and the thumb-nut d³ is screwed on to the pin, thus holding the
cover-plate firmly in place.
In Figure 2 is shewn a ring e of steel or other suitable metal in the interior of
the cover b, the ends of which ring may be jointed as shewn in Figure 3, in which e¹
is a cover-plate screwed or rivetted at eto one end of the ring e and provided with
Blotted holes ate through which pass pins or studs e which are screwed or rivetted
to the other end of the ring e as shewn. The edges of the ring e are preferably
beaded or rounded so as to prevent any damage to the cover b, and the ring itself
perforated as shewn at e, and if desired the ring may be bound round with horse-
hair, or horse-hair may be inserted between the ring and the cover.
In Figure 4 is shown a spring f wound helically in four or other convenient
number of convolutions and placed in the interior of the cover as shewn, the
helical convolutions being circumferential to the centre of the wheel. The con-
volutions of this spring f may also be clothed in horse-hair or other fibrous material
as explained with reference to the rim e Figure 2, and the two ends of the spring
may be turned inwards in order to avoid the possibility of damage to the cover b.
In this figure the plate d¹ is shewn flat, and adapted to receive the end of the
screw, the underside of the head of which serves to hold the cover plate & firmly
in place. It will be seen that the plate besides forming a means for securing
the cover plate d in place, also serves to prevent the inner edges b¹ of the cover b
from being forced out of position, and this is still more effectually provided for in
Figure 5, in which the edges b₁ of the cover b are beaded, and the ends of the
plate are correspondingly turned over so as to engage with the said beaded edges
of the cover.
In order to ensure a more or less continuous binding effect on the edges b¹ of the
cover 6 in the intermediate spaces between the holes d in the rim a, I sometimes
employ wires 9 as shewn in Figures 6 and 7 the latter figure being a section on
linex of Figure 6, looking towards the interior of the rim a. It will be seen
that the two wires 9 are continuous round the rim, and are locked in position at
intervals by the plates d¹. Or in some cases I employ separate plates such as
shewn in Figure 8, which plates h have holes d at either end to receive the screw-
pin (Figures 1, 2, 4, 5, 6 and 7) the intermediate portions 5 lying on the
edges b¹ of the cover b in the spaces between the holes d. It will be understood
that in this case each screw will pass through the holes in two adjacent
plates, the end of one plate overlapping the other.
Similar letters relate to like parts in all of the figures of the drawings.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
claim is:-
First. In elastic tyres for cycles and other vehicles, the employment of horse-

page_text: hair or other fibrous material introduced through openings formed in the rim, of
the wheel, which openings are fitted with closing devices, substantially as
described with reference to the drawings.
Second. In elastic tyres for cycles and other vehicles, the employment of a
resilient ring e, in combination, with a filling of horse-hair or other fibrous
material, substantially as described with reference to Figures 2 and 3 of the
drawings.
Third. In elastic tyres for cycles and other vehicles, the employment of a helical
spring formed of any convenient number of convolutions, in combination, with a
filling of horse-hair or other fibrous material, substantially as described with
reference to Figures 4 and 6 of the drawings.
Fourth. In elastic tyres for cycles and other vehicles, the employment of the
plate for securing the edges b¹ of the cover 6 in position, in combination with
the device for closing the opening a¹ in the rim a, substantially as described with
reference to the drawings.
Fifth. In elastic tyres for cycles and other vehicles, the employment of the
plate d and wires g, or plate h, for securing the edges b' of the cover b in position,
in combination with the device for closing the opening a¹ in the rim a, substan-
tially as described with reference to Figures 6, 7 and 8 of the drawings.
Sixth. The improvements in elastic tyres for cycles and other vehicles, substan-
tially as described with reference to the drawings.
