Improvements in and relating to the Handles of Cycles.
I, JOHN DODSON of 54, Church Road, Richmond, in the County of Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved device for fixing the handles of cycles
to the tubular bars intended to receive them, and it consists essentially of a
tapered bolt provided both with a drawing up nut also with a nut for attaching
the handle, and of a bush adapted to fit within the tubular handle bar and to be
expanded by drawing up the tapered bolt.
The bush is preferably made of wood but it may be made of any other suitable
material, durability, cheapness, and light weight being the essential points.
The tapered bolt may be made of any suitable metal and its tapered part is prefer-
ably fluted longitudinally or otherwise roughened to prevent it turning on being
drawn up by the nut screwed on its threaded end for the purpose.
By drawing up the tapered bolt it expands the split bush and thus firmly fixes
them both in the tubular handle bar. The handle which may be of any suitable
type and construction is then pushed on to the tubular handle bar and is made fast
to the end of the tapered bolt fixed therein by means of a suitably shaped nut
screwed on to the threaded end of the said bolt and engaging with the outer end
of the said handle.

Improvements in and relating to the Handles of Cycles.
I, JOHN DODSON of 54, Church Road, Richmond, in the County of Surrey,
Gentleman, 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 device for fixing the handles of cycles
to the tubular bars intended to receive them, and it consists essentially of a
tapered Jolt provided both with a drawing up nut and also with a nut for attaching
the handle, and of a bush adapted to fit within the tubular handle bar and to be
expanded by drawing up the tapered bolt.

page_text: In the accompanying drawing which illustrates a convenient method of carry-
ing my invention into effect:-
Figure 1 is a broken view-partly in section--of a handle and handle bar fitted
with my invention, and
Figure 2 is a view in section on line - of Figure 1.
Throughout both views similar parts are marked with like letters of reference.
A bolt A having a tapered or coned portion a is provided with a drawing up nut a¹
and with a nut a³ for attaching the handle X. The bolt A is passed through and
its tapered or coned portion a is adapted to engage with the walls of a hole in a
bush B in such a manner as to expand the said bush on screwing up the nut a!.
The bush B is preferably made of wood, but it may be made of any other
suitable material, durability, cheapness and lightness being the essential points,
and although it is shown split on the drawing to allow it to be readily expanded,
it may be inserted within the handle bar Y unsplit and caused to split by the
wedge like action of the tapered bolt, provided always that the wood is not too
close grained or tenacious.
To prevent the bolt A from turning within the bush B when the nut a¹ is being
screwed up to expand the said bush, the tapered or coned portion a is preferably
provided with longitudinal flutings or their equivalents.
After the bush B has been firmly fixed within the handle bar by screwing up
the nut a', the handle X which may be of any suitable shape and construction
is then pushed on over the handle bar and made fast to the bolt A. by means of
the nut a screwed on to the threaded end of the said bolt and engaging with the
outer end or cap al of the said handle.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. An improved device for fixing handles to the tubular handle bars of cycles
consisting essentially of a threaded bolt carrying two nuts and having a coned or
tapered part, and of a bush adapted to fit within the hollow handle bar and to be
expanded therein by the longitudinal movement of the said tapered bolt so as to
firmly fix both the bush and bolt within the said handle bar, the one nut on the
bolt being adapted to draw the tapered bolt into the bush and the second nut to
engage with the outer end or cap of the handle, as set forth.
2. An improved device for fixing the handles to the tubular handle bar of
cycles constructed arranged and adapted to operate, substantially as hereinbefore
described and shown.
