PROVISIONAL SPECIFICATION.
Improvements in Brakes for Bicycles, Tricycles, Motor Cycles,
and the like.
GEORGE FREDERICK CADDEN, of 36 Adelaide Street Coventry, Fitter do hereby
declare the nature of this invention to be as follows:-
In the place of the brake as at present applied to bicycles, tricycles, motor cycles
and the like which is worked by a lever and is liable in the case of the tyre being
punctured not to act in consequence of the tyre losing the air which has been
pumped into it and therefore becomes practically flat the reason it is ineffective
is because the lever can only be drawn up as far as the handle bar. It is proposed
therefore in the place of the brake as before described & which is worked from the
outside, to work it from the inside & in a more effectual manner as appears from
the following particulars. It will be seen that the drawing represents the handle
bar & fork, and their respective tubes, when out of the frame. The tube "F. T."
is attached to the fork crown and at its top end the handle bar tube "H. T" is
inserted; it is of course understood, that the handle bar th. H" is fixed to the
top of the tube "h. T." and these three parts "H. H" "H T." and "FT." work
together as though they were one and the same. My improvements is as follows,
At the bottom of the tube "F. T." is to be inserted the nut "N," which of course
has threads on its inside to enable the screw "s" to which is attached the tube "T"
to work, and this screw "S" with the tube "T" attached is worked by the
square rod "S. R" fitted in the square "A" of the tube "T"; the rod "S. R"
then passes through the handle bar "H. H" as shown by the drawing and it has
fastened at its top the Wheel "W" which is kept in its place by the screw "m"
and nut "K" and their joint action is as follows;-To raise or lower the brake,
turn the Wheel "W" either to the right or left for which-ever action is required.
The advantages claimed are (1) That it is more effectual and powerful
in its working and is practically out of sight. (2) That the handle bars of the
machine may be raised or lowered without the brake requiring readjustment, as
is the case at the present time. (3) That it may be applied to any shape of handle
bar without requiring any alteration.

I, GEORGE FREDERICK CADDEN 36 Adelaide Street Coventry, Fitter, do hereby

page_text: performed, to be particularly described and ascertained in and by the following
statement:-
In the place of the brake as at present applied to bicycles, tricycles, motor cycles
and the like which is worked by a lever and is liable in the case of the tyre being
punctured not to act in consequence of the tyre losing the air which has been
pumped into it and therefore becomes practically flat the reason it is ineffective
is because the lever can only be drawn up as far as the handle bar. It is proposed
therefore in the place of the brake as before described and which is worked from
the outside, to work it from the inside and in a more effectual manner as appears
from the following particulars. It will be seen that the drawing represents the
handle bar and fork, and their respective tubes, when out of the frame.
This invention relates to improvements in-brakes for velocipedes, the object
being to simplify the construction of the brake and at the same time conceal the
working parts from view which are carried in the hollow tube carrying the forks
in which the front wheel has its bearings.
In order that my invention may be fully understood, I will now refer to the
annexed drawing in which:-
Figure 1. Is a sectional front elevation shewing my brake attached to a
velocipede.
a. is the brake surface which is carried in the place b which is movable attached
to the hollow tube chaving a screw thread upon same and which engages in the
socket piece e. f. is a rod of square or other suitable section which engages in
the tube which is provided with a socket g of similar section. h. is a thumb piece
or wheel secured to the top of the rod f so that on rotating same the brake surface
is caused to engage upon the tyre of the wheel . j. is a disc or shoulder upon
the rod f and which maintains same in position rotating between the screwed
cap and the bearing formed in the top of the fork rod or handle bar.
great advantage of this brake is that in the event of the tyre becoming deflated
through being punctured the brake may be powerfully applied and thus prevent
an accident in the case of the tyre becoming punctured when riding down hill, as
in the lever brake now commonly used the brake surface has not sufficient
movement to enable it to engage with the tyre in the event of it becoming
deflated.

Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is:-
1. The combined construction & arrangement of the various parts substantially
as described.
2. In brakes for velocipedes, a hollow screwed tube working in a socket carrying
a movable brake surface, a rod of suitable section engaging in said hollow tube
through the medium of a socket; a thumb piece or wheel for rotating said rod
so that the brake may be applied to the surface of tyre of wheel and shoulder
upon said rod in order that the same may be retained in position between the
bearing and the screwed cap formed upon the hollow tube carrying the forks
or handle bar, said hollow tube carrying the forks enclosing the rod and screwed 4
hollow tube aforesaid.
