PROVISIONAL SPECIFICATION.
Improvements in and connected with Elastic Tyres.
I, THOMAS GARE, of Red House, Warren Drive, New Brighton, in the County
of Chester, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in and connected with elastic tyres
whereby resiliency, durability and cheapness are combined and existing solid
rubber tyres whether worn or not may be utilized.
To this end I employ as actual wearing surface a ring which I seat upon a
rubber or other elastic bed employed in a channel or similarly sectioned rim
which may form the felloe itself or be secured upon an ordinary felloe.
The said ring I may form of any suitable section, say tubular and round and
thicker at its outer periphery than at its inner or internally with a web so as to
render the ring strong and yet light, or I may form same in vertical sections,
say in three, the side sections being of metal and the inner section of some elastic
or yielding material, say rubber, leather or the like or of hard wood to render
the ring silent which sections are suitably secured together, or I may have a
channel in the outer periphery of the said ring filled with some elastic or yielding
material or wood.
The said elastic bed I may form with a V groove in which I press the said ring
by gradual cramping. The ends of the said ring when tubular I secure together
by a tongue having one end braized and the other after insertion pinned to the
ring.
To prevent the said ring from creeping on the said bed I may suitably pin it
to the rim or felloe of the wheel.
According to another form of my invention I may form any of the said con-
structions of ring in segments and when tubular I secure same upon the said
elastic bed to the felloe of the wheel by T or similar shaped bolts, the heads of
which are adapted to engage in the ends of the said tubular segments and the
shank in a hole formed wholly or partly through the felloe between the tube ends,
so that when screwing the nut of the bolt against the felloe the segments are
drawn tight against their beds, a suitable space being provided between the
tube ends to allow of depression of the segments.
If desirable the said tubular ring or segments may be be filled with some light
material, say rope, rendered water-proof, to prevent the accumulation of moisture
therein and provide a secondary wearing surface for use when the ordinary
surface has been worn through.
The said or similarly shaped bolts may be formed in one or two parts as may
be found most convenient and their shanks covered by rubber, leather, woven
tubing or the like for the purpose of rendering the tyre silent and protecting the
bolt against the influence of the weather. For the same purpose I also employ
between the felloe and nut and the head of the said bolt and segment ends rubber
or other elastic washers or pads.

page_text: Ordinary solid rubber tyres which hitherto when worn formed waste rubber
may be readily converted to any of the forms of my improved tyre without re-
moval from the iron channel by simply turning a groove into the same and
afterwards securing therein the ring or sections as described, or by reversing the
rubber in the iron channel.

Improvements in and connected with Elastic Tyres.
I, THOMAS GARE, late of Red House, now of Bramble Beach, Warren Drive,
New Brighton, in the County of Cheshire, Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to improvements in and connected with elastic tyres
whereby resiliency, durability and cheapness are combined and existing solid
rubber tyres whether worn or not may be utilized.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1, 4, 5 & 6 are various cross sections and Figs. 2 & 3 side views partly
in section of my improved elastic tyre.
In carrying out my invention and referring to Figs. 1 & 2, I employ as actual
wearing surface a ring a which I seat upon a rubber or other elastic bed bem-
ployed in a channel or similarly sectioned rim c which may form the felloe itself
or be secured upon an ordinary felloe d, as shown in the present instance.
The said ring may have any suitable section, say round or preferably oval and
when tubular thicker at its outer periphery than at its inner, or internally with
a web e, see dotted lines Fig. 1, so as to render it strong and yet light; or I
may form the same in vertical sections or layers, say three, as shown in Fig. 4,
the side sections f, f being of metal and the inner section 9 of some elastic or
yielding material, say rubber, leather, hard wood or other material which causes
the ring to run silent, which sections are suitably secured together, say by
rivets h; or again I may have a channel in the outer periphery of the said ring,
as shown in Fig. 5, filled with a strip of rubber, leather or other materiali
which will cause the tyre to run silent, partly folded and secured therein by a
metal insertion of taper section, as shown in Fig. 5.
The said ring I seat in a V or similar groove m formed in the said elastic bed
which supports the ring mainly at the sides and thus not only holds it much
firmer. in every direction, but will also give it more resiliency than what would
be the case, if the whole surface of the groove would be in contact with the ring.
The said ring I secure into the said elastic bed, by powerful gradual cramping,
say from spoke to spoke in such a manner that the said groove will mainly sup-
port the ring at the sides and its inner periphery will remain clear of the bottom
of the groove whilst the wheel is running under weight.
When the ring is used in a tubular form the ends I secure together whilst in
the cramp by a tongue n, see Fig. 2, having one end braized and the other after
insertion pinned to the ring, or as in the present instance made secure therein

page_text: by set screws o, or when the ring is used in a solid form, as shown in Figs. 4 & 5,
by splicing and pinning the same together as will be readily understood.
The ring seated and secured as described is not liable to creep on its bed or
yield to side thrust caused by skidding nor is it liable to spring or assume an
oval form and friction being thus prevented between the bed and ring, the bed
is not liable to wear nor the ring to break through torture of its fibres which
otherwise would be the case.
According to another form of my invention I may form any of the said con-
structions of rings, in segments and when tubular i secure same upon the said
elastic bed to the felloe of the wheel, as shown in Eig. 3, by T or similar shaped
bolts p, the heads of which are adapted to engage in the ends of the said tubular
segments and the shank in a hole formed wholly or partly through the channel
iron and felloe d between the tube ends, so that when screwing the nut of the
bolt against the felloe the segments are drawn tight against their beds, a suit-
able space being provided between the tube ends to allow of depression of the
segments.
If desirable the said tubular ring or segments may be filled with some light
material, say rope, rendered waterproof, to prevent the accumulation of moisture
therein and provide an auxiliary wearing, surface for use when the ordinary sur-
face has been worn through, as will be readily understood.
When using the ring section in a solid form 1 may also use Ṭ bolts for securing
the same, the heads of which are let into grooves formed in the ring ends as will
be readily understood.
The said Tor similarly shaped bolts may be formed in one or two parts as may
be found most convenient and their shanks covered by rubber, leather, woven
tubing or the like y for the purpose of rendering the tyre silent and protecting
the bolt against the influence of the weather. For the same purpose I also
employ between the felloe and nut and the head of the said bolt and segment ends,
rubber or other elastic washers or pads & s respectively.
Ordinary solid rubber tyres, see Fig. 6, dotted lines t, which hitherto, when
worn down to dotted line u formed waste rubber, may be readily converted to
any of the forms of my improved tyre without removal from the iron channel,
by simply turning a V or similar groove m into the same, see full lines and after-
wards securing therein the said ring or sections as described; or I may cut the
same in two parts, see dotted lines w; or again by taking out the worn rubber
and pressing it reversely into the iron channel which also provides a groove for
the ring or tyre section to rest on, see Fig. 7.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
1st. In elastic tyres, a round, oval or similarly sectioned ring wholly or partly
of metal, forming a wearing surface, in combination with a V or similarly
grooved elastic bed in a channelled sectioned rim, the said groove being so shaped
as to support the said ring or wearing surface mainly at the sides, all substantially
as and for the purpose set forth.
2nd. In a tyre such as specified in the preceding claim, securing the said ring.
or wearing surface into the groove of the said bed by gradual cramping until the
sides thereof become thoroughly imbedded in the said groove without the inner
periphery of the ring touching the bottom thereof and connecting the ends of the
said ring ends together whilst the ring is in the cramp, all substantially as and
for the purpose set forth.
3rd. In a tyre such as specified in the preceding claim, a tubular ring or wear-
ing surface formed in one piece having the ends connected together by a tongue
suitably secured thereto, all substantially as and for the purpose set forth.
4th. In a tyre such as specified in the preceding claim, forming the ring or

page_text: wearing surface tubular or solid in vertical layers suitably secured together and
of round, oval or similar section, all substantially as set forth.
5th. Converting ordinary or worn rubber tyres into such as specified in the pre-
ceding claims, by grooving or reversing the same in the rim of the felloe respec-
tively, all substantially as set forth.
