Engineer do hereby declare the nature of this invention to be as follows:-
The tee piece is fixed as usual in front wheel. I cut the top of tee piece in half
and fix a stud long enough to take the diameter of handle bar drill a hole in handle
drop over the stud screw down tight with nut. The down part of brake has a stop
to adjust pressure & slotted to keep break straight with wheel. By taking nut off
top of tee piece you lift handle bar part of brake away in half a minute, take it with
you and they cannot steal your machine while away or you move a ferule which
cover a joint each side of tee piece, on handle bar there is a nuckle joint in brake
handle you can drop handle bar and brake lever down for packing. It is most
simple in construction from in working and out of gear.

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 consists firstly an improved construction of detachable handle bar
and part of brake.
The tee piece of handle bar is fixed. I cut the level top of tee piece a in half
braze a plug in exposed hole of down piece drill tap & put in a stud long enough to
take diameter of handle bar drill a hole in handle bar fix by brazeing or otherwise
top half of tee piece a. I cut off, on handle bar, drop the handle bar over stud and
serew down tight with nut B with pin through it to turn nat so do away with
spanner. The down part of brake rod that goes in brake tube has an adjusting stop
fixed on the down piece and is stepped and the tube it goes in is stepped to fit.
The down piece is not fixed on tube but only droped in, the stepping is to keep the
brake wheel straight in contact with tyre.
My invention consists secondly in an improved construction of drop handle bar
and drop brake lever. I cut the handle bar about 4 in. from centre on each side

page_text: make joints F finished level with diameter of handle bar. The joints are kept in
working position by ferules g covering joints which ferules are fastened by screwing
on or by a pin or otherwise also a male & female joint H in brake handle rounded on
the underside of male part of joint so that the handle bars and brake handle drop
after moveing the ferules along the handle bars to about 8 in. wide.
I also square the hole I in guide for brake tube just above the shoe of
brake.
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 detachable handle bar & Brake handle bar as above described.
2 droped handle bars & Brake handle bar and steping for brake as above
described.
