PROVISIONAL SPECIFICATION.
Improvements in Rim Brakes for Bicycles, Tricycles, and the like.
HERBERT PICKLES, 19, Victor Road, Manningham, Bradford, Yorks, Architect,
do hereby declare the nature of this invention to be as follows:-
Fixed to the ordinary plunger of a bicycle brake, I have an oval shaped ring
or loop, passing over & down each side of the tyre (through a looped clip fixed
on each fork in the form of a foot rest) the ends of the loop turn under the rim,
& on the ends are fixed cross pieces, for bolting or rivetting pieces of leather,
rubber, or any other suitable material for pressing against the rim. The plunger
is connected to the brake lever in usual way, & the brake lever is connected to
the handle bar, in excentric, that is one end is hinged to the handlebar, on one
side of the centre, & the pull of the lever is on the other side, thus pulling the
brake up against the rim. On the plunger is fixed a spiral spring, working
against the lamp bracket or clip, thus pulling the brake back, above lamp bracket
is another small clip on plunger, to prevent plunger going down to far, I also
have a feather spring, between brake lever & handlebar. By means of bell
cranks & levers & rods I fix the brake on back wheel also.

Improvements in Rim Brakes for Bicycles, Tricycles, and the like.
HERBERT PICKLES, 19, Victor Road, Manningham, Bradford, Yorks, Architect,
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;-
-
These improvements relate to front wheel rim brakes for cycles & the like.
And in order that this my invention may be more readily carried into practical
effect, I have hereunto appended a sheet of drawings marked with letters of
reference, similar letters denoting similar parts in the various figures. The
brake as illustrated may be described in six portions. Fig. 1, shews front eleva-
tion of brake complete as when fixed on front of machine. Fig. 2 is a side eleva-
tion of brake as fixed on machine, shewing section of lever E & elevation of
top jaw as on ordinary plunger brake Fig. 3 is a plan & elevation of fork
clips J, for the oval ring or loop shaped spoon H, to slide up & down in loop L.
Fig. 4 is an elevation of feather spring which clips around handle bar G & fits
on lever E. Fig. 5, is a section of the usual clip for hingeing the brake lever

to handle bar. Fig. 6, is a plan of the looped brake spoon or oval shaped
ring H, shewing the projecting pieces or prongs M in full with the leather or
vulcanite covering K in dotted lines, & section of plunger tube A.-A, A, is
the usual plunger brake rod & tube. B is a clip for adjusting the tube & rod to
any length & locking the two together. C, is a clip fixed on plunger rod for
adjusting the plunger from going too far down, when the brake is not in use,
this is done by fixing the clip C, above the ordinary lamp bracket, which pre-
vents the plunger from going lower than required. D) is the usual jaw, fixed on
top of plunger rod A, for fixing the brake lever E in, in the usual way. N is
the usual hinge clip for fixing the end of brake lever E, to handlebar G.
the bottom of plunger A is fixed a loop or oval shaped ring H, better known as
a brake spoon, this loop passes thro' the ends of the side clips J at L which are
fixed on each side of the front wheel on the front forks as shewn in Fig. 1. The
clips J, act as slides at L for loop H to work up & down in. At the bottom of loop H
on each side of wheel is a cross piece or prong shewn in dotted lines M Fig. 2
& strong lines M, Fig. 6. These prongs are slightly tilted to a radius with the
wheel, to allow even fitting on the rim. Fixed on these cross pieces or prongs
are leather or vulcanite bobbins or cylinders K, these can be made of any suit-
able matérial. In practice it is found that these bobbins or cylinders K, will
fix themselves on without nuts or bolts, with the pressure of the prongs M
against the underside of the rim. In explaining the working of the brake,
pull up lever E which is fixed on the handlebar in eccentric that is one end of
lever E is hinged to handlebar by clip N on one side of centre, & the pull up
motion is on the other side of centre. When the lever is pulled up towards the
bar, this draws the loop H, H, up through the clips J, J; thus pulling the
cross pieces or prongs M, M, shielded with bobbins or cylinders K, K, up against
the rim of cycle wheel, & thus retarding its progress. When the upwards pull
is taken off lever E, the spring F which is fixed between lever E & handlebar
pushes down the lever, thus taking brake off the wheel. A spiral spring under
lamp bracket can be used also if desired as in the ordinary plunger tyre brake.
Having now particularly described and ascertained the nature of my said in-
vention & in what manner the same is to be performed, I declare that what I
claim is:
-
1. Manner of fixing oval loop or spoon, with side clips to front forks.
2. Manner of fixing bobbins or cylinders of leather or vulcanite to cross pieces
or prongs for friction against rim of cycle wheel.
