Improvements in Tyres and Rims for Cycles and other Vehicles.
I, BENJAMIN LOVELL, of 67, Kennington Park Road, Kennington, Agent,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved means for fixing the outer cover of
pneumatic tyres on cycles, and other vehicles, and consists of a special form of
rim with loose bands which grip the edges of the cover on the rim. The rim is
formed according to one arrangement, with turned over edges projecting inwardly.
The edges of the cover are laid over these parts, and are furnished with eyelet or
other holes, through which a number of screwed pins on the said rim edges project,
the pins being preferably fixed to the rim in any well known manner.
Around the edge of the cover so placed on each side, I place a strip of metal,
preferably of spring steel, bent round to the form of the rim, and consisting of a
single ring of required size, or of sections, which together form the ring. These
strips are also formed with holes corresponding to the positions of the screwed
pins, which project through them. After the strips are in place, they are secured
by means of small nuts screwed tightly on the pins, causing the retaining strips
and the rim to grip the edges of the cover tightly between them, all around the
circumference.
The outer edges of the said strips are preferably bent outward or formed with a
small beading to obviate any danger of cutting the cover. The extreme edges of:
the cover may also be formed thicker or having a fine wire embedded in them, the
edges extending just beyond the retaining strips, and rendering the fixing still
more secure, the thicker edges taking part of strain, and bearing against the edges
of the strips and rim.
Instead of bending the edges of the rim inwards, they may project outwards
slightly, the pins projecting from the inside of the rim, and the cover and retaining
strips fixed in a corresponding manner.
The method of fixing is identical with that above described, the form only being
slightly altered. The fixing strips may in some cases, be formed in one with the
rim, which is doubled over at the edge, forming a deep channel, the cover being
fixed as above described. These arrangements are applicable not only to rubber
covers, but could be used with a leather cover, should that be desired for heavier
vehicles than cycles.

COMPLETE SPECIFICATION.
Improvements in Tyres and Rims for Cycles and other Vehicles.
I, BENJAMIN LOVELL of 67 Kennington Park Road Kennington Agent 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 an improved means for fixing the outer cover of
pneumatic tyres on cycles, and other vehicles, also applicable to the fixing of
hollow non-inflated and solid tyres, and consists of a special form of rim with
loose bands which grip the edges of the cover or tyre on the rim. The rim is

page_text: formed, according to one arrangement, with turned over edges projecting inwardly.
The edges of the tyre are laid over these parts, and are furnished with eyelet or
other holes, through which a number of screwed pins on the said rim edges project.
the pins being preferably fixed to the rim in any well known manner.
Around
the edge of the cover so placed, on each side, I place a strip of metal, preferably
of spring steel, bent round to the form of the rim, and consisting of a single ring
of required size or of sections, which together form the ring. These strips are
also formed with holes corresponding to the positions of the screwed pins, which
project through them. After the strips are in place, they are secured by means of
small nuts screwed tightly on the pins, causing the retaining strips and the rim to
grip the edges of the cover tightly between them all around the circumference.
The outer edges of the said strips are preferably bent outward or formed with a
small beading to obviate any danger of cutting the cover. The extreme edges of
the cover may also be formed thicker or having a fine wire embedded in them, the
edges extending just beyond the retaining strips and rendering the fixing still more
secure, the thicker edges taking part of strain, and bearing against the edges of
the strips and rim. Instead of bending the edges of the rim inwards, they may
project outwards slightly, the pins projecting from the inside of the rim, and the
cover and retaining strips fixed in a corresponding manner. The method of fixing
is identical with that above described, the form only being slightly altered. The
fixing strips may in some cases be formed in one with the rim, which is doubled
over at the edges, forming a deep channel, the cover being fixed as above described.
These arrangements are applicable not only to rubber covers, but could be used
with a leather cover, should that be desired, for heavier vehicles than cycles.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which Fig. 1 is a cross section and Fig. 2
an elevation of one form of pneumatic tyre constructed according to my invention,
Figs. 3 and 4 are cross sections of slightly modified arrangements, Figs. 5 and 6
similar views of non-inflated hollow or cushion tyres, Fig. 5 showing one applied to
an ordinary cycle or similar rim, and Fig. 6 to a cab or like vehicle wheel, and
Fig. 7 a carriage tyre having a special form of rim, which can be fixed to the
felloes.
•
Referring to Figs. 1 to 4, A is the rim having edges a bent over according to
Figs. 1, 2 and 4 at an angle to the body of the rim. These edges are furnished
with screwed pins B, either fixed to them or loose and passing through them with
a retaining head at the back. The cover C, enclosing the inner air tube D is
pierced with a number of holes close to its edges which allow it to be placed over
the pins B, lying on the edges a of the rim. Over this is laid the narrow metal
strip E, formed with a beading around its edge to prevent any cutting of the
cover, fastened by means of the nuts screwing tightly on the pins B and causing
the strip to bind tightly on the cover all around the edge, thus gripping it firmly at
all points. To render the fixing more secure and even the edges of the cover are
made with a beading c preferably formed by means of a thin wire imbedded in the
edges in the usual manner. When the tyre is inflated this beading will be drawn
against the edge of the rim and the fixing strip unless the grip of the latter is
sufficiently strong to resist the force, and prevent any undue strain being thrown
on the pins or the canvas at those points. The nuts can be immediately applied
and detached by means of a small key.
In Fig. 1 the strip is fixed on the outside of the bent over edge of the rim, in
Fig. 3 on the underside, the edges not being bent over, and in Fig. 4 the strip is
formed in one piece with the rim, the edges of the cover lying in the channel so
formed.
According to the arrangement shown in Fig. 5 a cushion tyre is formed by a
thick strip C¹ of rubber bent or shaped into semicircular form in cross section,
with extended edges which are fixed in the same manner as those of the pneumatic
cover above described. The inside of the tyre forms shoulders which rest upon
the rim, the edges being of thinner material. The tyre C shown in Fig. 6, applied

page_text: to the rim A' of a cab or like wheel, is much after the same form as that shown in
Fig. 5, the rubber being formed with shoulders which rest on the rim, but it is
obvious that a solid tyre with projecting strips at the edges could be fixed in the
same manner. The rim or felloe A', with iron tyre a¹ around it, is perforated to
allow a bolt B' to pass through it from side to side, the two side fixing strips E
being applied in the manner above described and fixed by the nut b. The rim A'
in Fig. 7 is placed on the outside of the carriage wheel, the part a being employed
in the same manner as in the other views.
Having now particularly described and ascertained the nature of my said iuven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) A device for fixing tyres to cycles and other vehicles in which a metal strip
is employed around the edge of the rim, gripping the edge of the tyre between it
and the edge of rim by means of screwed pins and nuts or similar means,
substantially as described and for the purposes specified.
-
(2) In a means for fixing tyres to the rims of cycle and other wheels, a metal
strip at each side of the rim gripping the edge of the tyre between it and the bent
over edge of the rim by means of screwed pins and nuts substantially as described
and shown.
(3) In a means for fixing the outer cover of pneumatic tyres to rims, the
combination of a metal strip gripping the edge of the said cover between it and
the edge of the rim, with screwed pins and nut fixing the strip and a beading on
the edge of the cover substantially as and for the purposes specified.
(4) In a means for fixing the outer cover of pneumatic tyres the combination of
a rim with bent over edges on the outside of which the edges of the cover are laid,
each of the latter being provided with a beading, with strips placed on the edges
of the cover and fixed firmly by means of screwed pins attached to the rim and
passing through the cover and nuts on the said pins, substantially as described and
illustrated in Figs. 1 and 2 of the drawings.
(5) The modified arrangement in which the fixing strip E is formed continuous
with the rim, the tyres being fixed as claimed above, and the whole constructed
substantially as described and shown in Fig. 4 of the drawings.
