Improvements in or relating to Detachable Tyres for Cycle
and like Wheels.
We, HERMANN LOOG, of 36, Newgate Street, London, Manager, and RICHARD
RUSSELL GUBBINS, of 95, Pelton Road, East Greenwich, London, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention has for object, a novel construction and combination wheel
rim and side rings for locking thereto to constitute a tyre of a pneumatic or
other character for cycle and like wheels.
For the purpose of our invention, we use a rim to which the spokes of a wheel
are connected in any usual manner. The rim has a turned in flange wholly or
partially around it from both edges. In conjunction with the rim thus specially
made, we employ two hollow or outwardly flanged rings, each having one flange
or lip curled over towards the centre of the annular channel formed by said
flanges.
The flat or comparatively flat flange of each ring is intended to engage within
the inwardly flanged portion of the rim, the channel under the curled lip or
flange forming the space for the edge of the cover of the tyre, whether it be
pneumatic, solid, or of any other kind.
The invention is chiefly intended for pneumatic tyres of cycle and like vehicle
wheels, over which air tube the cover can be bound on in any desired manner.
such as by wire or cord wrappings or lacings, or by beaded edges to be rolled
or forced into the channels.
The rim and one side ring constructed as before explained may be in one
piece, or as fixtures to each other in which case only one side ring would be
affixable.
We purpose leaving a gap at one or more parts of the rim flange or flanges
to enable the rings to be sprung into position with facility and for easy removal
when required.

This invention has for object a novel construction and combination wheel

For the purpose of our invention "We use a rim to which the spokes of a
wheel are connected in any usual manner: The rim has a turned in flange,
wholly or partially around it from one or from both edges. In conjunction with
the rim thus specially made, we employ two hollow, or outwardly flanged rings,
each having one lip curled over to engage the Hange of the rim and another
which is curled inwardly towards the centre, forming an annular channel formed
for the location of the edges of the cover or of edges to a solid or cushion-tyre.
The invention is chiefly intended for pneumatic tyres of cycles and like vehi-
cles over which air tube the cover can he bound on in any desired manner, such
as by wire or cord wrappings or lacings, or by beaded edges to be rolled or forced
into the channels.

The rim and one side ring constructed as before explained, may be in one
piece. or as fixtures to each other, in which case only one side ring would be
affixable.
We purpose leaving a gap at one or more parts of the ring flange or 'flanges
to enable the rings to be sprung into position with facility, and for easy removal
when required. The gap is coverable by a hinged strip, or by a separate strip
held to the inner tube by the valve fixings.
Our invention will be understood by reference to the annexed drawings.
Fig. 1 is a transverse section of a rim A and tyre and in which the rim has
flanges B, B¹, turned inwardly towards each other, and Fig. 2 a transverse sec-
tion of a pneumatic tyre with rim A, having two flanges B, B¹ turned inwardly
towards the centre of the rim, for the greater part of the circumference as shown
at Fig. 3, which is a face view of a rim A with spokes C and hub D.
E is the gap or unflanged portion of rim A, as at Fig. 3, and coverable by a
hinged strip E shown in dotted lines. F, F, Figs. 1 & 2, are detachable rings
of about the same circumference as the flanges B, B', within or under which the
ribs G. G₁ are capable of being pushed or sprung so that the curled over por-
tions H, H', project and form annular pockets into which the edges,I, I, of
the tyre cover J can be located when pushed in. K is the inflated or pneumatic
tube. La liner strip for the pneumatic tube to lie upon, and be protected from
direct contact with the metal of the rim A or of the spoke heads or other pro-
jections.
Fig. 4, represents the rim A. with one curled edge ring as part of same, the
other ring F, alone being detachable.
In Fig. 1, the hinged strip E¹ is dispensed with and a loose piece of metal
may be sprung under the flanges B, B1, to cover the valve or be secured by the
valve fixings but, when making up the wheel as at Fig. 2, any part of the rings
flanges or ribs G, G¹, can be inserted into the gap or opening E and under the
rim flange B, or B, and then by a continued pressure on the ring, and a slight
guidance by the hand the ribs G or G¹ can be gradually inserted to complete
the attachment, or by placing any part of the ring lip G or G¹, over the flange B
or B, nearest the ground and by slightly closing the other part of the ring by
pressure towards the centre the lip G or GI can be caused to engage within the
rim flange B or B¹, until it reaches the gap E and then can be sprung in to form
a perfect bite circumference and become part of the tyre with the additional
means of fastening the edges I, II, of the cover J to the wheel, the fixture
being by inflation of the pneumatic tube K or by doubling plain edges of the
cover into the channel and binding with wire or cord..
The invention is only shown as applied to a pneumatic tyre, but if a solid

page_text: rubber of cushion tyre be used, said tyre can be moulded with beaded or plain
edges for insertion into the annular channels.
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:-
1. A wheel rim A with flanges B, B', turned inwards as at Fig. 1 & 2, hollow
rings F, F, one lip G or G¹, engaging with the rim flange B or B', the other
lip or lips H or H by the curl forming a channel within which the edges of
the cover J can be secured as specified.
2. Constructing pneumatic tyre rims A having turned in flanges B, B¹, each
with a recess or gap E, in the circumference, as and for the purpose specified
said gap being coverable by a strip El.
