PROVISIONAL SPECIFICATION.
Improved Means for Fastening Tyres for Velocipedes and other
Road Carriages.
I, EDWARD HENRY SEDDON of Marsland Road, Brooklands in the County of
Chester Commercial Traveller do hereby declare the nature of this invention to be
as follows:
This invention relates to hollow tyres for velocipedes and other road carriages,
fixed to the rims of the wheels by means of wires or bands surrounding the rim
and held in grooves of the same, and consists in improved means for tightening and
locking said wires or bands, the improvements being more particularly intended for
tyres open on the underside or of horseshoe section.
My improvements consist firstly in the employment of bridge-pieces or plates of
metal or other inflexible substance having bosses turned up from the plate or
formed as swellings at each end for the extremities of the wire or band to pass
through, and cut out on the underside between the swellings or formed with slots
therein for the use of nuts nipples or their equivalents and vulcanised or cemented
to the sides of the tyre. Or, the plates may be formed and secured in a manner to
support or suspend a lap or turnover of the material of the tyre through which lap
the band may pass, the object of the employment of the plates being to tie down
the portion of the tyre at the joint or break of the band equally with the remaining
portion. The ends of the wires or metal pieces connected to the bands may be
screwed with a screw thread and the two extremities of the band may be drawn
together by means of a suitable coupling or a right and left hand tapped nut or
nipple, or in the case of the bossed or swelled bridges or slotted plates the
extremities of the band may be secured with nuts or heads formed thereon in any
convenient manner inside the bridge or slotted plate. In place of nuts or nipples
screwed upon the ends of the band I may employ plates or attached heads thereto
as hereinafter described.
My further improvement relates to the employment of plates or equivalent pieces
for tightening and securing the wires or bands. These plates are formed with a boss
or swelling or equivalent thereof at one side which is tapped and screwed or
otherwise secured to the extremities of the band under the bridge-piece or in the
slotted plate. The plates preferably project to the outside of the rim through a
slot cut in the side or turned up edge of the same, when V sectioned rims are used,
or through the bottom of the rim when flat in section or solid in other forms. The
plates are formed outside the rim with slots or their equivalents and are drawn
together by a special tool hereinafter described and when drawn together are
secured by a cramp or made to overlap and be secured by a cotter or equivalent
fastening passed through both, or by other suitable means. Instead of being passed
through the rim the plates may be bent over the edge of the same or may lie in
the rim in such a manner that the special tool aforesaid may by passing into the slot
in the rim or into the channel therein otherwise, grasp the plates and draw them
together.
My further improvement consists in the construction of tools for drawing said
plates together. These tools may be constructed similarly to an adjustable screw
spanner or in combination with the same, or after the manner of a pair of pliers
having a screw for closing the same, the jaws being formed with projections or in a
manner to fit into the slots or their equivalents in the plates, or with equivalent
means for gripping the plates in such a manner that the tool cannot slip its

page_text: hold and the plates be not deflected inwards by the action of the tool upon
them.

page_text: piece is attached to the envelope by cementing it thereto but preferably secured
thereto as shewn by Figs. 1 and 2, or Figs. 8 and 9. In the arrangement shewn by
Figs. 1 and 2 the wire g is embedded in the edge of the envelope a or in a loop
formed by the canvas lining a' thereof and turned over on the inside and cemented
to the body of the lining. The bridge piece is in that case cemented to the inside
of the canvas lining and the latter turned over the luge at the ends and the middle
bar towards the inside and cemented to the body of the lining. In the arrangement!
shewn by Figs. 8 and 9 the edge of the envelope is turned up on the outside and
the wire g passed round the bottom of the fold, as shewn by Fig. 9. The bridge
piece is in that case preferably cemented to the lining a¹ on the outside, the rubber
part of the envelope being cut away, and' the lining folded round the lugs and
middle bar and cemented to the envelope on the outside, as shewn by Fig. 8. The
plates may also be formed without bosses at their ends and be secured to or support.
a lap or turnover of the tyre through which lap the band or wire passes, the object
of the bridge piece being as herein before stated to tie down or hold the portion y z
of the tyre at the joint or coupling of the wire or band equally with the remaining-
portion and prevent its being bulged out as aforesaid, and to allow room for and
access to the fastenings underneath the bridge piece.
Instead of the bridge pieces or plates being cut out on the underside, they may
be formed with longitudinal slots for giving access to the ends of the wire or
bands.
The ends of the wires or of pieces connected to the bands may be screwed with a
screw thread and the two extremities of the band or wire drawn together by a right.
and left hand tapped long nut or. nipple, or in the case of bossed swelled bridge
pieces as shown on the drawings the ends of the wire may be secured by nuts at.
both ends or a head at one end and a nut at the other screwed up against the
bosses or . Instead of these arrangements I preferably use a coupling or
connection that can readily be drawn together by means of a handy special tool and
locked in position. Such an arrangement is shewn on the drawings. Upon one
end of the wire is screwed a nipple i formed with a hook and upon the other end a
nipple having a shackle k¹ connected to it. The ends of the wire are drawn
together by means of a tool, which may have the form of a pair of plyers or tongs.
as shewn by Fig. 10 on a reduced scale, the jaws m m of which have slots m² m²
into which the wire can enter when the jaws are opened and placed behind the
nipples ik. When these are drawn together the shackle can be slipped over the
hook and the coupling locked thereby; for unfastening the same the nipples need
only be drawn together sufficiently to remove the shackle from the hook. The
nipples prevent the ends of the wire from being withdrawn into the loops or edge of
the envelope a when the latter is distended for passing it over the edge of the
rim c.
Instead of a coupling as described, the nipples ik or their equivalents may be
formed with projections either inside of the rim c or extending through slots of the
rim to the outside of the same, which when the nipples are drawn together can be
secured by a clamp, or said projections may be made to overlap each other and be
fastened by means of a cotter or bolt passed through both or by equivalent
means. For the purpose of drawing the nipples together a tool constructed
similarly to a coach wrench or adjustable spanner with slotted jaws may be used
instead of the plyers or tongs shewn by Fig. 10, but I make no special claim for
said tools.
Both sides of the envelope a of the tyre may be fastened by the means herein-
before described, but preferably I divide the envelope on one side of its sectional
circumference as shewn in Fig. 2, so that one edge & rests on the bottom of the rim
and covers the holes made for the insertion of the spokes and protects the air tube
against abrasion by them, and bind this edge to the rim by means of a wire d
passed round the same inside the envelope, the edge being formed with a beading b
as shown to prevent its being drawn outwards from under the wire d by the inflation
of the air tube.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The use for fastening the envelopes of hollow flexible wheel tyres to the rims of
wires or bands and bridge pieces and attachments arranged substantially as herein-
before described and for the purposes set forth.
