IMPROVEMENTS IN BICYCLE TRICYCLE AND OTHER WHEELS AND, IN THE INDIA-RUBBER TYRES AND METAL RIMS OR FELLOES OF THE SAME
Year: 1884

page_text: I THOMAS CLARKE of 180 Stockport Road Ardwick Manchester in the County
of Lancaster Bicycle and Tricycle Manufacturer, do hereby declare the nature of
my invention for IMPROVEMENTS IN BICYCLE TRICYCLE AND OTHER WHEELS
AND, IN THE INDIA-RUBBER TYRES AND METAL RIMS OR FELLOES OF THE SAME
to be as follows:-
The first part of this invention relates to a novel method of securing the spokes
in position and whereby it is rendered possible to take out a spoke and replace it
by a new one without disturbing or removing the india rubber tyre-This is
effected by arranging the spokes to pass loosely through the flange on the hub and
there to be formed with a screwed portion with a head at that extremity of the
spoke The other extremity of the spoke is screwed into a fixed nut secured
to the metal rim and so that when tightened up so as to bring the heal against
the inside of the flange the same can be locked in position by a Lock-nut screwed
onto the lower extremity of the spokes herein before mentioned.
This invention also consists in forming a groove with straight parallel sides
slightly widened out at the mouth and with a curved base in the metal rim or
felloe of Bicycles Tricycles and other wheels and in felloe of Bicycles Tricycles and
other wheels and in forming the india-rubber of a similar corresponding cross
section to such groove so that the same can be cemented in position along the
curved base whilst the straight parallel sides afford a protection to effectually
prevent the tyre coming out of the groove.
Dated this fourteenth day of March 1884.

page_text: I THOMAS CLARKE of 180 Stockport Road Ardwick, Manchester, in the County
of Lancaster, Bicyle and Tricyle Manufacturer do hereby declare the nature of
my invention of "IMPROVEMENTS IN BICYLE, TRICYLE AND. OTHER WHEELS, AND
IN THE INDIA-RUBBER TYRES AND METAL RIMS OR FELLOES OF THE SAME and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
"
The first part of this invention relates to a novel method of securing the spokes
in position and whereby it, is rendered possible to take out a spoke and replace it
by a new one without disturbing or removing the india-rubber tyre.
On the accompanying drawing Fig 1-represents a sectional view of part of a rim
and hub of a bicyle, or other wheel with a spoke applied thereto in accordance
with my invention. I arrange the spoke a to pass freely through the flange b on
the hub c and there to be formed with a screwed portion d and with a countersunk
head e at that extremity of the spoke.
The other extremity f of the spoke a is screwed into a fixed nut g secured to
the metal rin g¹ by a set screw halso, with a countersunk head and so that when
tightened up so as to bring the head e against the inside of the flange b the same
can be locked in position by a lock nut screwed on to the screwed portion c. In
this manner of fixing the spokes it will be apparent that it is rendered possible to
remove one or more spokes or to tighten the spokes in position without disturbing
or removing the india-rubber tyre. Fig 2 represents a sectional view of my
improved rim or felloe and Fig 3 a similar view of the india-rubber tyre for the
same Fig 4 represents the same india-rubber tyre in position in the rim or felloe.
This part of my, invention consists in forming the groove.j in the rim or felloe of
Bicyle, Tricyle and other wheels with straight parallel side k and with a curved
base and in forming the india-rubber tyre n of a similar corresponding cross
section so that the same can be cemented in position along the curved base whilst
the straight parallel sides of the groove and thus such tyre is effectually prevented
coming out of the groove whilst running."
Having thus particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I claim as my
improvements in Bicyle, Tricyle and other wheels and in the india-rubber tyres
and metal rims or felloes of the same,
1 The improved, method of mounting and securing the spokes in position
substantially as and for the purposes, hereinbefore described and illustrated on the
accompanying drawing.
2nd Constructing the groove in the rim or felloe with straight parallel sides and
with a curved base and the india-rubber tyre of a similar cross-section substantially
as and for the purpose hereinbefore described and illustrated on the accompanying
drawing.
Dated this 13th day of December 1884.
