PROVISIONAL SPECIFICATION.
Improvements in and connected with the Tyres of Cycles, Carriages,
and other Vehicles.
I, WILLIAM HERBERT SEWELL, of Harbour View, Port-Stewart, Ireland, General
Produce Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in and connected with the tyres of
cycles, carriages, and other vehicles, and is a further development of my prior
Patent bearing No. 27086 A.D. 1897, and has for its object the providing of a
somewhat simplified form of section and a more effective form of attachment to
that referred to in my prior Patents.
In carrying out my invention I propose to have sections or segments, which,
instead of being supported or depending from the rim by a flange and neck attach-
ment, will be clamped or latched to the rim face by a suitable spring clamp
or clamps, which will pass through suitable openings and engage with or upon
ground face of rim of wheel.
Dated this 19th day of December 1898.
Improvements in and connected with the Tyres of Cycles, Carriages,
and other Vehicles.
I, WILLIAM HERBERT SEWELL, of Harbour View, Port-Stewart, Ireland, General
Produce Merchant, 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:-
-
My invention relates to improvements in and connected with the tyres of cycles,
carriages, and other wheeled vehicles and is a following-up or improvement upon
my previous Patent No. 27086 A.D. 1897, the essential differences consisting in
some modifications of the separate sections of which the tyre is composed, and
improved methods of attaching or affixing same to, on, or within the wheel rim.
My proposition now is that the tyre be composed of a series of hollow chambered
rubber sections or balls similar to those described and claimed in my said prior
patent (or I may use solid rubber sections the construction of which latter will
hereafter be explained) in combination with a wheel rim similar to that described
in the said prior patent, riz., a rim so constructed as to provide for a sympathetic
upward or backward expansion of the top or background of the sections or balls

page_text: when the running face or apex of latter is deformed or compressed by being
brought into ground contact. In my previous Patent No. 27086 A.D. 1897 it was
provided that the sections were moulded or made with a neck and a tangential or
flattened head and the attachment to rim was by said head being forced or pressed
through an orifice in ground face of rim equal in diameter to the neck. As an
alternative I now propose that the balls or sections be made without a neck and
head out with an elongated flange or base and that the attachment shall be by a
circumferential metal ring encircling the ball or section and resting against flange
or base of same. The whole is then attached to the rim by spring clips or arms
with barbed or broadened heads which bestride or depend from the ring, pass
through the flange of section and latch, hook, or button themselves upon or within
rim face.
In order that my invention may be properly understood and readily carried into
effect, I have hereunto appended one sheet of drawings, of which,
Figure 1 is a longitudinal section of part of rim of wheel and tyre of cycle
showing my improvements.
Figure 1 is separate view shewing more clearly the barbed head of clip bearing
within rim.
Figure 2 is a plan.
Figure 2 is section shewing construction of ball.
Figure 3 is a detached view in plan of part of rim of wheel with tyre removed
and attachment ring in position.
Figure 4 is a detached view in plan and side elevation of attachment ring, which
encircles the ball and bears against the elongated buffer flanges.
Figure 5 is separate view in front and side elevation of the spring clip with
barbed and arrow head, which fitting over the ring passes through the flange of
ball and suitable openings on rim face and latches on latter.
Figures 6 and 7-8 and 9-10 and 11 are views of different modifications of a
spring or catch attachment engaging with, on, or within rim in a suitable manner.
A is the rim of the wheel, (wood or metal) having the ground face B provided
with circular openings C at suitable distances apart, to provide for an upward
expansion of segment when ground tread is under pressure, thereby suspending
and absorbing vibration, and D are the small holes through which the spring
clips E pass, E¹ are the elongated buffer flanges of the balls F which latter are
made open and afterwards closed by a lid with a dovetailed joint. This enables
the ball to be moulded under compression both inside and out so that the wall is
uniform and free from imperfections. G is the ring which encircles the ball
and bears against the elongated buffer flanges E, and E are the spring clips which
have a barbed and arrow head a (Figure 5) and which pass over or bestride the
ring G and thence through the small holes D in the flanges E¹ and engage with the
ground face B of rim of wheel thereby firmly latching or clamping the sections or
balls of the tyre to the rim of the wheel.
In Figures 6 and 7, 8 and 9, and 10 and 11, I have shewn different modifications
of the spring clips or arms for latching or clamping the sections or segments to
the rim of the wheel. Referring to Figures 6 and 7, the holes D in the ground
face B are made of keyhole construction and the ring G has rigidly secured to
and depending from it four arms or projections J having button heads K. These
heads pass through the openings D and a slight lateral push forward of the sections
will ensure the button heads being locked in the narrow end of the keyhole open-
ings D. Figures 8 and 9 show a ring with depending arms having springy
ends J¹ so that after passing through the openings D the ends spring apart or
astride and engage with the under surface of the ground face B. In Figures 10
and 11, in place of the holes D I have a slot K on each side of the circular
openings C and the clip in this case passes through the slots when the springy
piece m springs out and engages or bears upon the underside of the ground face
of the rim and so clamps or latches the sections or segments to the rim of the wheel.
This latter form of attachment may be more properly styled a buckle,

page_text: Of course there may be other forms of spring or latch attachments which might
equally serve the same purpose.
Figures 2 and 2° are respectively cross section and longitudinal section of a
solid rubber ball which I may use, the attachments being similar to those already
described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
1. In the tyres of cycles, carriages, and other vehicles constructing the sections
substantially as described and illustrated on the accompanying sheet of drawings.
2. The method of clamping, latching, or attaching the sections to the rim face
spring clips, substantially as described and
of wheel by means of rings
and
or
illustrated on the accompanying drawings.
