Improvements in Fastenings and Fittings for Tyres of Cycle and
other Wheels.
I, GEORGE THOMPSON, of Glendale, Church Road, Moseley, in the County of
Worcester, Chartered Accountant, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the manner in which I construct and arrange the
fastening appliances and fittings for use in securing pneumatic and other tyres to
the rims of wheels for bicycles, tricycles and other vehicles, whereby 1 am enabled
to more readily attach or remove the tyre, to or from the rim of a wheel than is at
present possible with the existing systems of securing such tyres to the wheel
rims.
In carrying my invention into effect in one manner I provide and arrange upon
the pneumatic tyre a number of projecting bosses or hollow pins of india rubber,
which hollow pins or bosses I preferably vulcanise in order the more effectually to
receive and hold the connecting pins or screws which I employ for passing through
the rim of the wheel. These projecting bosses or pins I cause to enter and fit into
suitable holes which I provide within the rim of the wheel in such a manner that
when the holes are thus entered, the metal screws or studs may pass right through
the inner edge of the tyre rim to a sufficient extent to permit of the attachment of
a washer and nut for rigidly securing the tyre to the rim..
The screws or studs I form with a flat surface on one side in order that a washer
with a similarly shaped hole may be placed over each stud to prevent its turning
when the nut is being tightened up; the underside of the washer I shape to suit
the configuration of the tyre.
I provide any desired number of bosses, and screws upon the rubber tyre in order
that a rigid connection and binding attachment may be obtained between the tyre
and the rim.
Sometimes I connect the projecting screws or studs to the rubber bosses of the
tyre by forming a rough thread or a series of rings upon the circumference of the
lower end of the studs, and on passing the studs into the bosses of rubber I wind
fine binding wire around the outside of the rubber bosses in order to make a secure
connection between the metal studs and the rubber bosses or projections.
cause
By another method I secure the tyres to the rims of the wheels by employing a
number of metal screws or studs which I attach to the tyres by means of projecting
flanges or heads formed upon the ends of the studs or pins, and these flanges
to enter into the tyre through holes in such a manner that the pin portions only
project through the tyre to pass through the holes in the rim of the wheel, while
the flanges remain within the tyre. I place nuts and washers on the projecting
screws inside the rim in the manner hereinbefore described.
I also employ my flanged pins or screws for the same purpose but instead of
passing flanges into the tyre I cause them to rest upon and be secured to the
rubber by means of a sheet of rubber which I preferably vulcanise to the main
portion or body of the tyre; or I pass a strip of linen or other suitable material
over the pins to cover the flanges, the strip of material being secured to the rubber
in any well known manner.
By my improved systems of connecting tyres to the wheel rim of velocipedes and
other vehicles, am also enabled to very effectually and permanently maintain the

COMPLETE SPECIFICATION.
Improvements in Fastenings and Fittings for Tyres of Cycle and
other Wheels.
I, GEORGE THOMPSON, of Glendale, Church Road, Moseley, in the County of
Worcester, Chartered Accountant, 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 the manner in which I construct and arrange the
fastening appliances and fittings for use in securing pneumatic and other tyres to
the rims of wheels for bicycles, tricycles and other vehicles, whereby I am enabled
to more readily attach or remove the tyre, to or from the rim of a wheel than is at
present possible with the existing systems of securing such tyres to the wheel
rims.
In the two accompanying sheets of explanatory drawings
Figure 1 is a sectional clevation of one method of attachment and Figure 2 is a
part elevation of the same.
Figure 3 is a sectional elevation of a modification of my improved attachment.
Figure 4 is a section and Figure 5 a plan of the cap or washer cup which I
employ to protect the projecting boss A of my attachment.
Figure 6 is a detail elevation of my improved bolt or screw, and Figure 7 is
a plan.
Figure 8 is a sectional elevation of a wheel with my improved tyre shown in
position, and Figure 9 is a part elevation of the same.
Figure 10 is a sectional front elevation and Figure 11 a sectional side elevation
showing a method of attachment sometimes employ having a tee or plate headed
bolt resting inside one portion of the tyre and with the screwed portion or pin
projecting through and beneath the wheel rim.
Figure 12 is a sectional elevation of my improved attachment with the tee or
plate headed bolt outside the tyre but resting on a sheet of rubber H on the rim
of the wheel.
Figure 13 is a sectional elevation showing a double screw attachment I employ,
the screws by preference being arranged in a "zig zag" around the wheel rim:
Figure 14 is a side clevation of the same.
Figure 15 is a detail front elevation, Figure 16 a side elevation and Figure 17 a
reverse plan of my improved tee or plate headed bolt or pin G, G¹.
In carrying my invention into effect in one manner I provide and arrange upon
the pneumatic tyre a number of projecting bosses or hollow pins A of india-rubber
shown in Figures 1, 2, 8 and 9, which hollow pins or bosses I preferably vulcanize
in order the more effectually to receive and hold the connecting pins or screws B
which I employ for passing through the rim C of the wheel. These projecting
bosses or pins AI cause to enter and fit into suitable holes « which I provide
within the rim of the wheel in such a manner that when the holes are thus entered,
the metal screws or studs may pass right through the inner edge of the tyre rim C
to a sufficient extent to permit of the attachment of a washer or cap D and nut E
for rigidly securing the tyre F to the rim.
The screws or studs B I form with a square neck or with a flat surface b on one
side in order that a washer with a similarly shaped hole d may be placed over each
stud to prevent its turning when the nut is being tightened up; the underside of
the washer D I shape to suit the configuration of the tyre...

page_text: I provide any desired number of bosses and screws upon the rubber tyre in order
that a rigid connection and binding attachment may be obtained between the tyre
and the rim. Sometimes I connect the projecting screws or studs to the rubber
bosses of the tyre by forming a rough thread or a series of rings upon the circum-
ference of the lower ends of the studs as shown in Figure 3, and on passing the
studs B into the bosses of rubber I wind fine binding wire around the outside of
the rubber bosses in order to make a secure connection between the metal studs
and the rubber bosses or projections.
il
By another method I secure the tyres to the rims of the wheels by employing
number of metal screws or studs which I attach to the tyres by means of projecting
flanges or heads formed upon the ends of the studs or pins G as shown on Sheet 2
Figures 10, 11, 15 and 17, and these flanges GI cause to enter into the tyre F
through holes in such a manner that the pin portions G only project through the
tyre to pass through the holes in the rim of the wheel, while the flanges G reinain
within the tyre. I place nuts and washers on the projecting screws inside the rim
in the manner hereinbefore described.
I also employ my flanged pins or screws for the same purpose but, as shown in
Figures 12 and 13, instead of passing flanges into the tyre cause them to rest
upon and be secured to the rubber by means of a sheet of rubber which I
preferably vulcanize to the main portion or body of the tyre F; or I pass a strip
of linen or other suitable material over the pins to cover the flanges, the strip of
material being secured to the rubber in any well known manner.
By my improved systems of connecting tyres to the wheel rim of velocipedes
and other vehicles, I am also enabled to very effectually and permanently maintain
the tyres upon the wheels in hot countries where the ordinary solution connection
between the rim and the tyre is liable to fail under the influence of the heat.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction and arrangement of cycle wheel and like tyre fittings and
attachments for securing the pneumatic or hollow tyre to the rim of the wheel,
substantially as and for the purposes hereinbefore described.
2. The construction of india-rubber tyres for wheels having projecting bosses of
rubber such as A. for receiving pins or studs to be employed for attaching the tyre
to the rim of the wheel.
3. In a cycle or like wheel, the method of attaching india-rubber tyres to the
rims by means of enlarged tee or plate headed bolts and nuts, the heads passing
either inside or being connected to the outside of the tyre, substantially as herein-
before described and as illustrated in Figures 10, 11, 12, and 13 of the accompanying
drawings.
